In some embodiments, the first heat exchange component 2 includes at least one heat exchange monomer 22. In the examples shown in FIGS. 1 and 20, the first heat exchange component 2 includes a heat exchange monomer 22. 13 and 14, the first heat exchange component 2 includes a plurality of heat exchange cells 22 spaced apart in the left and right direction, that is, on a plane parallel to the left and right direction, the heat exchange cells 22 There is no overlap in the orthographic projection. Therefore, by arranging the first heat exchange part 2 to include a plurality of heat exchange monomers 22, compared to setting the first heat exchange part 2 as a whole heat exchange monomer, the heat exchange monomers can be effectively shortened. The length of 22 in the front-rear direction facilitates the processing of a single heat exchange unit 22.

Wherein, multiple heat exchange monomers 22 are connected in parallel and/or in series: multiple heat exchange monomers 22 are arranged in parallel, at this time, the inlets of multiple heat exchange monomers 22 are connected, and the outlets of multiple heat exchange monomers 22 are connected; Or a plurality of heat exchange monomers 22 are arranged in series, at this time the outlet of one of the two adjacent heat exchange monomers 22 is connected to the inlet of the other; or at least two of the plurality of heat exchange monomers 22 are arranged in series, at least Two heat exchange monomers 22 are arranged in parallel, for example, there are three heat exchange monomers 22, one of the heat exchange monomers 22 is connected in parallel with the other two heat exchange monomers 22, and the other two heat exchange monomers 22 are arranged in series. Therefore, the multiple heat exchange monomers 22 are arranged flexibly, which facilitates the heat exchange device 100 to better meet the differentiated needs of users.

For example, when a user installs and uses the heat exchange device 100, the first wall surface A is the front wall of the housing 1 facing the user, and the second wall surface B is the rear wall of the housing 1. The first air inlet 101 penetrates through the first wall surface A and is formed on the first wall surface A, and the distance L1 between the first heat exchange component 2 and the inner surface of the first wall surface A is smaller than the first heat exchange component 2 and the second wall surface The distance L2 between the inner surfaces of B, that is, in the front-rear direction, the distance L1 between the first heat exchange member 2 and the inner surface of the first wall surface A is smaller than the inner surface of the first heat exchange member 2 and the second wall surface B Compared with the inner surface of the second wall surface B, the first heat exchange component 2 is arranged closer to the inner surface of the first wall surface A, and the inner surface of the first heat exchange component 2 and the second wall surface B An upstream communication chamber 111 may be defined between the surfaces. The upstream communication chamber 111 has a larger volume. When the heat exchange device 100 is used for cooling, the upstream communication chamber 111 stores cold air with a density greater than that of the outside air. Conducive to the convergence of cold air, the cold air accelerates its natural sinking under the action of gravity.

Wherein, since the first air inlet 101 penetrates the first wall surface A, the distance L1 between the first heat exchange component 2 and the inner surface of the first wall surface A refers to the edge of the first heat exchange component 2 and the first air inlet 101 The distance between the planes.

Because the upstream communicating chamber 11111 has a large volume, it is convenient for a large amount of cold air to gather. A large amount of cold air is driven by gravity, which is conducive to the spontaneous drop of cold air. For example, cold air can sink to the first air outlet 102 and be discharged through the first air outlet 102 to realize the refrigeration of the heat exchange device 100; at the same time, due to the sinking of the cold air in the upstream communication chamber 111, the upstream communication The upper part of the chamber 111 forms a low-pressure area. Driven by the pressure difference, the hot air outside the housing 1 (which can be understood as the air with a higher temperature) will continuously flow from the first air inlet 101 to the housing 1 to interact with The first heat exchange component 2 performs heat exchange, so that the circulation of air flow and cold and heat changes can be realized without or with a small amount of active driving device such as the exhaust component 3, and the refrigeration cycle of the heat exchange device 100 is guaranteed to continue. get on.

The first air outlet 102 is indirectly connected, and the upstream communication chamber 111 and the downstream communication chamber 112 together constitute the communication chamber 11, so that the communication chamber 11 has a larger volume, which is conducive to the collection of cold air and further enhances the naturalness of the cold air. Sinking effect.

In other examples, the first heat exchange component 2 is arranged in contact with the inner surface of the second wall surface B. At this time, the upstream communication chamber 111 and the inner surface of the second wall surface B are not defined between the first heat exchange component 2 and the inner surface of the second wall surface B. Or the small space between the first heat exchange component 2 and the inner surface of the second wall surface B forms an upstream communication chamber 111, and the lower side of the first heat exchange component 2 is provided with a downstream communication chamber 112 and a downstream communication chamber 112 Defined by the inner surface of the first wall surface A and the inner surface of the second wall surface B, the downstream communication chamber 112 communicates with the airflow channel of the first heat exchange component 2, so as to ensure the natural sinking effect of the cold air, and at the same time It is beneficial to save the occupied space of the heat exchange device 100.

Due to the large volume of the space Ω2, it is convenient for a large amount of cold air to gather, and a large amount of cold air is driven by gravity, which is conducive to the spontaneous generation of cold air. Sinking, for example, cold air can sink to the first air outlet 102 and be discharged through the first air outlet 102 to realize the cooling of the heat exchange device 100; at the same time, due to the sinking of the cold air in the space Ω2, the upper part of the space Ω2 A low pressure area is formed. Driven by the pressure difference, the hot air outside the housing 1 (which can be understood as higher temperature air) will continuously flow from the first air inlet 101 to the housing 1 to communicate with the first heat exchange component. 2 Perform heat exchange, so that the circulation of air flow and cold and heat changes can be realized without or with a small amount of active driving device such as the exhaust component 3, which ensures that the refrigeration cycle of the heat exchange device 100 continues.

It can be understood that when the first heat exchange component 2 includes a plurality of first single-row heat exchange tube groups 21, the plurality of first single-row heat exchange tube groups 21 are sequentially arranged in the front-to-rear direction, and each first single-row Each of the heat exchange tube groups 21 has a first plane 2a on which a plurality of first heat exchange tubes 211 are arranged, and the outermost two first planes 2a in the front-rear direction are taken, and each point on one of the first planes 2a is summed with A plurality of line segments are formed between points on the other first plane 2a to connect the two first planes 2a, and the plane defined by the centers of the plurality of line segments is the center plane of the first heat exchange component 2. At this time, the orthographic projection of the center surface of the first heat exchange component 2 and the center surface of the first heat exchange component 2 on the first wall surface A along the front-rear direction and the corresponding projection line form a space Ω1, that is, the space Ω1 is defined by the first heat exchange The center surface of the component 2 and the inner surface of the first wall surface A define the orthographic projection and the corresponding projection of the center surface of the first heat exchange component 2 and the center surface of the first heat exchange component 2 on the second wall surface B along the front-rear direction The line forming space Ω2, that is, the space Ω2 is defined by the center surface of the first heat exchange component 2 and the inner surface of the second wall surface B.

In some embodiments, as shown in FIGS. 4, 5 and 7-9, and as shown in FIG. 12, the first heat exchange component 2 includes a first single-row heat exchange tube group 21, and a first single-row heat exchange tube group 21 Including a plurality of first heat exchange tubes 211 with a centerline on the first plane 2a, the included angle α'between the first plane 2a and the up-down direction satisfies -5°≤α'≤5°. Among them, when α'is non-zero, the first plane 2a has an intersection with the vertical direction. If the angle of α'is positive, the straight line parallel to the vertical direction rotates counterclockwise around the intersection until it is parallel to the first plane 2a, and the rotation angle is α ', if the angle of α'is negative, the straight line parallel to the vertical direction rotates clockwise around the intersection point to be parallel to the first plane 2a, and the rotation angle is -α'; when α'is 0°, the first plane 2a is parallel to Set up and down.

In some embodiments, as shown in FIGS. 38 and 12, the first plane 2a is parallel to the first wall surface A, and the first plane 2a is parallel to the first direction. The first direction is the vertical up and down direction. If the wall surface A extends vertically, the first heat exchange component 2 is arranged vertically as a whole, thereby saving the space occupied by the first heat exchange component 2 in the third direction, which is beneficial to reduce the outer profile of the heat exchange device 100 in the third direction. The size, the thin design of the heat exchange device 100 is realized.

The arrangement plane of the first heat exchange component 2 is a plane defined by the arrangement direction of the plurality of first heat exchange tubes 211 of the first heat exchange component 2 and the extension direction of each first heat exchange tube 211 described above. ; The first plane 2a is set parallel to the first wall surface A, which may mean that the arrangement plane of the first single-row heat exchange tube group 21 is parallel to the first wall surface A. When the first heat exchange component 2 includes a first single-row heat exchange tube group 21, for example, the first heat exchange component 2 is a single-row serpentine heat exchanger, and the arrangement plane of the first heat exchange component 2 may be the same as the first plane 2a. Understand as the same plane. In other embodiments, the first heat exchange component 2 includes a plurality of first single-row heat exchange tube groups 21, and the first heat exchange component 2 has a plurality of arrangement planes arranged in parallel and spaced apart.

For example, in the examples shown in FIGS. 38 and 20, the first wall surface A extends in the first direction, and the first heat exchange component 2 includes a first single-row heat exchange tube group 21. The first heat exchange tubes 211 are arranged at intervals along the first direction, and each first heat exchange tube 211 extends in the second direction, so that the first heat exchange component 2 is arranged in the first direction as a whole; but it is not limited to this.

In some embodiments, the first wall surface A extends along the fourth direction, the fourth direction intersects the first direction at a non-zero included angle, and the fourth direction is perpendicular to the second direction. The first heat exchange component 2 includes a first single In the row heat exchange tube group 21, the multiple first heat exchange tubes 211 of the first single-row heat exchange tube group 21 are arranged at intervals along the fourth direction, and each first heat exchange tube 211 extends in the second direction, such that, The first heat exchange component 2 is arranged in the fourth direction as a whole; but it is not limited to this.

In other embodiments, the first plane 2a is arranged non-parallel to the first wall surface A, that is, the arrangement direction of the first single-row heat exchange tube group 21 is inclined with respect to the first wall surface A.

In some embodiments, as shown in Figs. 1, 10-12 and 18, and Figs. 35 and 37, the housing 1 also has a second air inlet 104, and the air outside the housing 1 comes from the second air inlet. 104 flows into the housing 1, so that the heat exchange device 100 has a larger air inlet area, and the heat exchange efficiency of the heat exchange device 100 is improved. The second air inlet 104 and the first air inlet 101 are spaced apart in the vertical direction, and the second air inlet 104 is located on the side of the first air inlet 101 away from the first air outlet 102, and in the vertical direction, the first air inlet 104 101 is located between the second air inlet 104 and the first air outlet 102, that is, on a plane parallel to the up and down direction, the orthographic interval of the first air inlet 101 is located between the orthographic projection of the second air inlet 104 and the first air inlet 104. Between the orthographic projection of the air outlet 102. Therefore, by reasonably setting the position of the second air inlet 104, the heat exchange performance of the heat exchange device 100 can be further improved. For example, in some embodiments, the housing 1 is provided with a first air inlet 101 and a second air inlet. The heat exchange device 100 of 104 can improve the performance of the heat exchange device 100 by about 30% compared to the heat exchange device 100 in which only the first air inlet 101 is provided on the housing 1.

For example, in the examples of FIGS. 1, 10-12 and 18, 35, 37, and 38, the first air inlet 101 is formed on the front wall of the housing 1, and the first air outlet 102 is provided at intervals Below the first air inlet 101, the second air inlet 104 is arranged above the first air inlet 101 at intervals.

In other words, the second air inlet 104 and the first air inlet 101 are formed on the same wall surface of the casing 1 or are formed on different wall surfaces of the casing 1 respectively. The air outside the housing 1 can flow into the housing 1 from the first air inlet 101 and the second air inlet 104 respectively, which is beneficial to increase the air intake volume of the heat exchange device 100, thereby improving the heat exchange performance of the heat exchange device 100.

In some embodiments, as shown in FIGS. 10-14, 35, 38, and 41, the heat exchange device 100 further includes a second heat exchange component 4, and the first heat exchange component 2 includes a first single-row heat exchange The tube group 21, the first single-row heat exchange tube group 21 includes a plurality of first heat exchange tubes 211, the center lines of the plurality of first heat exchange tubes 211 enclose the first plane 2a, and the second heat exchange component 4 includes a second The single-row heat exchange tube group 41. The second single-row heat exchange tube group 41 includes a plurality of second heat exchange tubes 411. The center lines of the plurality of second heat exchange tubes 411 enclose the second plane 4a, and the first plane 2a is connected to The second plane 4a has a non-zero included angle, that is, the included angle between the arrangement plane of the second heat exchange component 4 and the arrangement plane of the first heat exchange component 2 is not equal to 0°.

For example, the first plane 2a is arranged vertically, and the second plane 4a is arranged obliquely along a direction with an angle not equal to 0° with the vertical direction, which is beneficial to realize the second heat exchange component 4 relative to the first heat exchange component 2 Reasonable arrangement makes the arrangement of the second heat exchange component 4 and the first heat exchange component 2 more compact, prevents the second heat exchange component 4 and the first heat exchange component 2 from occupying a large space in a certain direction, and can improve the heat exchange at the same time The heat exchange area of the device 100 improves heat exchange efficiency and enhances the heat exchange effect; when the heat exchange device 100 is used for refrigeration, it further facilitates the gathering of a large amount of cold air, facilitates the spontaneous sinking of cold air, and reduces wind resistance.

Wherein, the arrangement plane of the second heat exchange component 4 is defined by the arrangement direction of the plurality of second heat exchange tubes 411 of the second single-row heat exchange tube group 41 and the extension direction of the second heat exchange tubes 411 described above. flat. When the second heat exchange component 4 includes a second single-row heat exchange tube group 41, for example, the second heat exchange component 4 is a single-row serpentine heat exchanger, and the arrangement plane of the second heat exchange component 4 may be the same as the second plane 4a. Understand as the same plane. In other embodiments, the second heat exchange component 4 includes a plurality of parallel second single-row heat exchange tube groups 41, and the second heat exchange component 4 has a plurality of arrangement planes arranged in parallel and spaced apart.

As shown in Figures 10-12, 38, and 41, at least part of the orthographic projection of the second heat exchange component 4 in the front-rear direction is staggered from the orthographic projection of the first heat exchange component 2 in the front-rear direction, that is, perpendicular to On the plane in the front-to-rear direction, at least part of the orthographic projection of the second heat exchange component 4 is staggered from the orthographic projection of the first heat exchange component 2, that is, on a plane perpendicular to the front-to-rear direction, the second heat exchange component 4 At least part of the orthographic projection of the first heat exchange component 2 does not overlap with the orthographic projection of the first heat exchange component 2. It can also be understood that at least part of the orthographic projection of the second heat exchange component 4 is located in the first heat exchange component on a plane perpendicular to the front-to-rear direction. In addition to the orthographic projection of the component 2, it is further conducive to the rational layout of the first heat exchange component 2 and the second heat exchange component 4, so that the heat exchange device 100 can better take into account the inlet of the first air inlet 101 and the second air inlet 104 at the same time. The wind prevents air from flowing through the first heat exchange component 2 and the second heat exchange component 4 in sequence, and prevents the second heat exchange component 4 from causing a large wind resistance to the air after heat exchange with the first heat exchange component 2.

In the examples shown in Figures 10-12, Figure 38, and Figure 41, the orthographic projection of the second heat exchange component 4 is completely staggered from the orthographic projection of the first heat exchange component 2 on a plane perpendicular to the front-to-rear direction, that is, the first The orthographic projection of the second heat exchange component 4 does not coincide with the orthographic projection of the first heat exchange component 2 at all, that is, the orthographic projection of the second heat exchange component 4 is outside the orthographic projection of the first heat exchange component 2. Of course, in some other examples of this application, the orthographic projection of the second heat exchange component 4 overlaps with the orthographic projection of the first heat exchange component 2 on a plane perpendicular to the front-rear direction, that is, the orthographic projection of the second heat exchange component 4 is partially overlapped. A part of the orthographic projection falls within the orthographic projection of the first heat exchange component 2, and the other part falls outside the orthographic projection of the first heat exchange component 2.

As shown in Figs. 15-17, the second heat exchange component 4 and the first heat exchange component 2 are connected in parallel and/or in series. In some embodiments, as shown in FIG. 15, the second heat exchange component 4 is arranged in parallel with the first heat exchange component 2, and the inlet of the second heat exchange component 4 is connected with the inlet of the first heat exchange component 2, and the second heat exchange component 4 is connected to the inlet of the first heat exchange component 2. The outlet of the part 4 is connected to the outlet of the first heat exchange part 2, a part of the heat exchange medium is distributed to the second heat exchange part 4 and the other part is distributed to the first heat exchange part 2. In other embodiments, as shown in FIG. 16, the second heat exchange component 4 is arranged in series with the first heat exchange component 2, and the heat exchange medium flows through the first heat exchange component 2 and the second heat exchange component 4 in sequence, or It flows through the second heat exchange part 4 and the first heat exchange part 2. In still other embodiments, as shown in FIG. 17, the second heat exchange component 4 is connected in parallel and in series with the first heat exchange component 2. For example, there are multiple first heat exchange components 2, and at least one first heat exchange component 2 is connected to the first heat exchange component 2. Two heat exchange components 4 are connected in series, and at least one first heat exchange component 2 is connected in parallel with the second heat exchange component 4, or there are multiple second heat exchange components 4, and at least one second heat exchange component 4 is connected to the first heat exchange component 2 are connected in series, and at least one second heat exchange component 4 is connected in parallel with the first heat exchange component 2. Therefore, the flexible arrangement between the second heat exchange component 4 and the first heat exchange component 2 is beneficial to improve the structural diversity of the heat exchange device 100. Among them, the heat exchange medium is refrigerant or water. When the heat exchange medium is used for cooling, the heat exchange medium can flow into the first heat exchange part 2 from the lower part of the first heat exchange part 2 and flow out from the upper part of the first heat exchange part 2, and the air can be roughly inside the housing 1. Flowing from top to bottom makes the heat exchange medium and the air generally arranged in a countercurrent flow, which is beneficial to improve the cooling effect of the first heat exchange component 2.

As shown in Figs. 10-12, Figs. 38 and 41, at least part of the second heat exchange component 4 is located on the side of the first heat exchange component 2 close to the second air inlet 104 in the upper and lower direction. That is, the first heat exchange component 2 has a first end 20a and a second end 20b in the up-down direction. The first end 20a is located close to the second air inlet 104, and the second end 20b is located away from the second air inlet 104 and is vertically positioned. On the plane in the up and down direction, the orthographic projection of the second heat exchange component 4 and the orthographic projection of the first end 20a at least partially overlap, so that the air flowing into the housing 1 through the second air inlet 104 facilitates contact with the second heat exchange component 4 The heat exchange is beneficial to reduce the thickness of the heat exchange device 100; the cold air after the heat exchange directly sinks, and there is no need to turn in the flow path of the cold air, so that the resistance of this part of the cold air is small, which is beneficial to enhance the natural fall of the cold air. The sinking effect accelerates the spontaneous flow of airflow. At the same time, the sinking of this part of the cold air creates a negative pressure on the downstream side of the first heat exchange component 2, which is beneficial to drive more outside air into the housing 1 through the first air inlet 101 in the left and right directions. Inside, and after the heat exchange with the first heat exchange component 2, it turns in the up and down direction along with the cold air after the heat exchange with the second heat exchange component 4 sinks to the first air outlet 102 to flow out, which is beneficial to realize the circulation of air flow. , Improve the heat exchange efficiency; when the heat exchange device 100 is used for refrigeration, the condensed water generated by the second heat exchange component 4 can be collected together with the condensed water generated by the first heat exchange component 2, which facilitates the collection and discharge of the condensed water.

For example, in the examples shown in Figs. 10-12, Figs. 38 and 41, the second air inlet 104 is located above the first heat exchange component 2, the second heat exchange component 4 is provided in the housing 1, and the second heat exchange At least part of the component 4 is located above the upper end of the first heat exchange component 2. At this time, along the up and down direction, the orthographic projection of the second heat exchange component 4 can overlap with the orthographic projection of the upper end of the first heat exchange component 2. A part of the second heat exchange part 4 is located directly above the upper end of the first heat exchange part 2, and another part of the second heat exchange part 4 is located obliquely above the upper end of the first heat exchange part 2; or along the up and down direction, the second heat exchange The orthographic projection of the component 4 all falls within the orthographic projection of the upper end of the first heat exchange component 2, and the second heat exchange component 4 is completely located directly above the upper end of the first heat exchange component 2. Thus, the condensed water generated by the second heat exchange component 4 can flow down to the first heat exchange component 2 to be collected together with the condensed water generated by the first heat exchange component 2, which is beneficial to the discharge of the condensed water.

It can be understood that in some other embodiments of the present application, the housing 1 does not have the second air inlet 104. In still other embodiments, the heat exchange device 100 does not have the second air inlet 104 and the second heat exchange component 4 is not provided, so that the number of parts of the heat exchange device 100 is small, the structure is simple, and the reasonable layout of the components of the heat exchange device 100 is facilitated. .

In some embodiments, as shown in FIG. 12, the housing 1 includes a first wall surface A and a second wall surface B opposite to each other in the front-to-rear direction, and the housing 1 is provided with a first heat exchange component 2 and a second heat exchange component. 4. The upstream communication chamber 11 is defined between the first heat exchange component 2 and the second wall surface B. The downstream communication chamber 112 is provided on the lower side of the upstream communication chamber 111, and the downstream communication chamber 112 is defined by the first wall surface A. The inner surface and the inner surface of the second wall surface B are defined so that the upstream communication chamber 111 and the downstream communication chamber 112 together constitute the communication chamber 11, and at least part of the second heat exchange component 4 is located in the first heat exchange component 2 The side close to the second air inlet 104 in the up and down direction; in the up and down direction, the height of the communicating chamber 11 is H', and the sum of the heights of the first heat exchange component 2 and the second heat exchange component 4 is h, then H'and h satisfy 0.2<h/H'≤1, which is beneficial to the actual structural layout of the heat exchange device 100, while ensuring the overall effect of the heat exchange device 100. The smaller the value of h/H', the storage of cold air The larger the space, the more cold air is stored, and the gravity effect of the cold air is enhanced, thereby enhancing the spontaneous sinking effect of the cold air, which is beneficial to improving the performance of the heat exchange device 100.

In some embodiments, as shown in Figs. 10-12, Figs. 38, and 41, the second heat exchange component 4 is along the direction from the first air inlet 101 to the first heat exchange component 2 in the front-to-rear direction. The up and down direction extends obliquely along the direction from the first air inlet 101 to the second air inlet 104. For example, the second heat exchange member 4 extends obliquely from front to back and from bottom to top, which is beneficial to further enhance the heat exchange of the heat exchange device 100. The heat area can better utilize the second air inlet 104, so that the air flowing into the housing 1 through the second air inlet 104 can better exchange heat with the second heat exchange component 4, and improve the heat exchange efficiency; When the heating device 100 is used for refrigeration, the cold air formed after heat exchange with the second heat exchange component 4 and the cold air formed after heat exchange with the first heat exchange component 2 can be gathered in a large amount, which facilitates the spontaneous sinking of the cold air, and Under the action of the inclined arrangement of the second heat exchange component 4, the vertical downward velocity component of the cold air formed after heat exchange with the second heat exchange component 4 is increased, which further improves the sinking effect of the cold air and reduces the cold air The number of changes in the flow direction reduces the wind resistance. At the same time, the condensed water generated by the second heat exchange component 4 can flow downward along the inclined direction of the second heat exchange component 4, which facilitates the collection and collection of the condensed water.

It can be understood that the inclination angle α of the second heat exchange component 4 with respect to the vertical direction can be specifically set according to actual applications, for example, α can satisfy -30°≤α≤30°.

In addition, the arrangement of the second heat exchange component 4 is not limited to this. In some embodiments, the second heat exchange component 4 is arranged parallel to the front-to-rear direction. For example, during installation and use, the second heat exchange component 4 is arranged horizontally.

In some embodiments, as shown in FIG. 18, the heat exchange device 100 further includes an air deflector 6, which is movably arranged at the first air outlet 102 to adjust the direction of the air from the first air outlet 102 And/or opening and closing the first air outlet 102 includes the following situations: (1) the air deflector 6 moves relative to the first air outlet 102 to adjust the direction of the air from the first air outlet 102; (2), the air deflector 6 Move relative to the first air outlet 102 to open and close the first air outlet 102; (3) the air deflector 6 moves relative to the first air outlet 102 to adjust the direction of the first air outlet 102, and the air deflector 6 realizes the first The opening and closing of the air outlet 102.

For example, the air deflector 6 is formed as a deflector, and the movement of the deflector changes the direction of the air from the first air outlet 102. To a certain extent, it is beneficial to further expand the air supply range of the heat exchange device 100, so that the entire The indoor air can form a large-scale circulation; of course, the baffle can also be used to open and close the first air outlet 102. For another example, the air deflector 6 is formed to open and close the door, and the first air outlet 102 is opened and closed by the movement of the opening and closing door, the first air outlet 102 is opened to realize the normal air outlet of the first air outlet 102, and the first air outlet 102 is closed. In order to prevent external dust and the like from entering the housing 1 through the first air outlet 102, to ensure the cleanliness of the heat exchange device 100; of course, the opening and closing of the door can also be used to adjust the air outlet direction of the first air outlet 102.

In some embodiments, as shown in Figures 12, 38 and 41, the heat exchange device 100 further includes an air-inducing structure 7, which is arranged opposite to the first air outlet 102 in the front-to-rear direction, and the air-inducing structure 7 has The guide surface 71 extending toward the first air outlet 102, the guide surface 71 guides the airflow in the housing 1 toward the first air outlet 102, which is beneficial to reduce the flow resistance of the airflow and realize the smooth flow of the airflow to the first air outlet 102.

In the example of FIG. 12, the first air outlet 102 is formed on the front wall surface of the housing 1, the air guide structure 7 is located on the rear side of the first air outlet 102, and at least part of the front wall surface of the air guide structure 7 forms a flow guide. Surface 71; the air guiding structure 7 is formed as a deflector, and the cross section of the deflecting surface 71 is formed as a curve, such as a circular arc, to smoothly guide the heat exchanged air toward the first air outlet 102, which is beneficial to the smooth forward air flow Send out. Among them, the diversion angle of the diversion surface 71 is between 0° and 90° (including the endpoint value) to better meet the requirements of different scenarios.

It can be understood that, in some examples, the outer surface of the air guiding structure 7 is a part of the outer surface 10 of the housing 1; in other examples, the air guiding structure 7 is provided in the housing 1.

In some embodiments, as shown in FIG. 12, the first air outlet 102 is formed on the front wall surface of the housing 1, a water blocking structure 14 is provided at the lower end of the first air outlet 102, and the water blocking structure 14 is formed as a water blocking strip. , The water blocking strip extends vertically upward from the lower end edge of the first air outlet 102, or extends upward obliquely, so as to prevent the condensed water generated on the inner wall of the housing 1 from dripping into the room through the first air outlet 102, ensuring indoor cleanliness . Of course, the water blocking structure 14 may not be provided at the first air outlet 102.

In some embodiments, as shown in Figure 3, Figure 6-Figure 12, Figure 37-Figure 39 and Figure 41, the first heat exchange component 2 is provided with an interface on the side close to the first air outlet 102 in the vertical direction. The water box 5, the water receiving box 5 is used to collect the condensed water generated by the first heat exchange component 2; at least part of the orthographic projection of the water receiving box 5 in the up and down direction falls on the orthographic projection of the first heat exchange component 2 in the up and down direction Inside, that is, on a plane perpendicular to the up and down direction, at least part of the orthographic projection of the water receiving box 5 falls within the orthographic projection of the first heat exchange component 2, and in the up and down direction, the first heat exchange component 2 can block the connection At least part of the water box 5 is convenient to ensure that the water receiving box 5 can effectively collect the condensed water generated by the first heat exchange component 2, and at the same time, it is beneficial to reduce the occupied space of the water receiving box 5 and avoiding the water receiving box 5 in the front-to-rear direction. Excessive length causes greater wind resistance to the air after the heat exchange, thereby reducing the cost of the water receiving box 5, and further conducive to the spontaneous sinking of the cold air.

Among them, most of the orthographic projection of the water receiving box 5 can occupy more than half of the total area of the orthographic projection of the water receiving box 5.

Of course, the application is not limited to this. In some embodiments, as shown in FIG. 9, on a plane perpendicular to the up and down direction, the orthographic projection of the water receiving box 5 all falls within the orthographic projection of the first heat exchange component 2. In the up and down direction, the first heat exchange component 2 can completely shield the water receiving box 5, thereby further reducing the wind resistance of the water receiving box 5, which is conducive to the spontaneous sinking of cold air.

In some embodiments, the water receiving box 5 is arranged on the housing 1, and the water receiving box 5 is arranged below the first heat exchange component 2 at intervals.

In some embodiments shown in Figure 13, Figure 37, the water receiving box 5 extends linearly, and there is an angle β between the extending direction of the water receiving box 5 and the left and right directions, and β may be greater than 0°, so that the water receiving box 5 is opposite to each other. It is arranged obliquely in the left and right directions, so that the condensed water collected in the water receiving box 5 flows spontaneously to the end of the water receiving 5, which facilitates the discharge of the condensed water; among them, β can satisfy 2°≤β≤10°. Of course, the present application is not limited to this. For example, as shown in FIG. 14, the water receiving box 5 includes a first water receiving portion 51 and a second water receiving portion 52. Extending downwards in the direction of each other, the connection between the first water receiving portion 51 and the second water receiving portion 52 is the lowest, which also facilitates the discharge of condensate water. Among them, the first water receiving portion 51 and the second water receiving portion 52 are connected to each other. The connection point can be located at any position of the water receiving box 5 in the left-right direction.

In some embodiments, as shown in Figures 8 and 9, Figure 41 and Figure 42, an inclined portion 20 is formed on a surface of the first heat exchange component 2 close to the water receiving box 5, and at least part of the inclined portion 20 is opposite to each other. Inclined in the up and down direction, at least part of the inclined portion 20 is along the direction from the first heat exchange component 2 to the water receiving box 5 in the up and down direction, and along the front and back direction from the first heat exchange component 2 to the first air inlet The direction 101 extends obliquely. For example, at least part of the inclined portion 20 extends obliquely from top to bottom and from back to front. Then the condensed water generated by the first heat exchange component 2 can flow downward, and the condensed water is flowing to the inclined portion 20. At this time, the condensed water can flow along the above-mentioned at least part of the extension direction of the inclined portion 20 and finally flow to the water receiving box 5. Therefore, the inclined portion 20 can guide the flow of condensed water, so that when the condensed water flows from the first heat exchange component 2 to the water receiving box 5, the space occupied by the condensed water in the front and rear directions is small, which can reduce The width of the water receiving box 5 in the front-to-rear direction further reduces the wind resistance caused by the water receiving box 5.

For example, in the examples of Figures 8 and 9, Figures 41-44, the first heat exchange component 2 is a tube and fin heat exchanger, and the tube and fin heat exchanger includes a plurality of heat exchange fins 212, and a plurality of heat exchange fins 212. The fins 212 are arranged at intervals, and each heat exchange fin 212 extends in the up and down direction. The heat exchange fins 212 can guide the flow of condensed water. The inclined part 20 is formed on the rear side of the lower edge of the heat exchange fin 212, and the inclined part 20 goes from top to bottom. 、Extend obliquely from back to front, so that the width of the lower edge of the heat exchange fin 212 in the front and rear direction is small, and the width of the lower edge of the heat exchange fin 212 is smaller than the width of the upper edge of the heat exchange fin 212, which is convenient for guiding the condensed water to the water receiving box 5. In some embodiments, as shown in FIGS. 8 and 9, the first heat exchange component 2 includes a plurality of first heat exchange tubes 211 and a plurality of heat exchange fins 212, and the plurality of first heat exchange tubes 211 are spaced in the up and down direction. Arrangement, a plurality of heat exchange fins 212 are arranged at intervals in the left and right direction, the distance l between two adjacent first heat exchange tubes 211 satisfies 14mm≤l≤25mm, each heat exchange fin 212 extends in the up and down direction, each A heat exchange tube 211 extends in the left-right direction to sequentially pass through a plurality of heat exchange fins 212, and the front end of the inclined portion 20 extends forward to not exceed the vertical outer tangent line of the rear side of the first heat exchange tube 211; When the front end extends forward to the vertical outer tangent to the rear side of the first heat exchange tube 211, the front end of the inclined portion 20 and the rear side wall of the first heat exchange tube 211 are arranged up and down.

It can be understood that the included angle γ between the inclined portion 20 and the front-rear direction can be specifically set according to actual applications; in some embodiments, γ satisfies 50°≤γ≤85°, for example, γ is 60°.

As shown in Figures 7-9, Figure 43 and Figure 44, the top of the water receiving box 5 is open to form a water receiving port 50. In the left-right direction, the width of the water receiving port 50 is greater than or equal to the width of the lower edge of the heat exchange fin 212; When the width of the water receiving port 50 is equal to the width of the lower edge of the heat exchange fin 212, the water receiving port 50 and the lower edge of the heat exchange fin 212 are aligned up and down, which is beneficial to reduce the wind resistance generated by the water receiving box 5. As shown in Fig. 9, the rear side wall of the water receiving box 5 is arranged obliquely with respect to the front-to-rear direction, and the rear side wall of the water receiving box 5 extends from top to bottom and from back to front to further reduce the water receiving box 5. The generated wind resistance prevents the airflow from forming a large stagnant area under the water receiving box 5, and ensures the smooth flow of the airflow.

Wherein, the angle between the rear side wall of the water receiving box 5 and the vertical direction is 0°<δ≦40°, for example, δ is 20°.

In some embodiments, as shown in FIGS. 20-25, the first heat exchange component 2 includes a plurality of heat exchange fins 212 spaced apart in the left and right direction, and the adjacent heat exchange fins 212 are spaced apart from each other in the left and right direction. If the value range is 2mm-10mm (including the endpoint value), there is an appropriate distance between two adjacent heat exchange fins 212, which is beneficial to reduce the wind resistance generated by the heat exchange fins 212, facilitate air flow, and improve heat exchange efficiency.

In some examples of the present application, as shown in FIGS. 20-25, the first heat exchange component 2 is a tube-fin heat exchanger, and the tube-fin heat exchanger includes a plurality of first heat exchange tubes 211 and a plurality of heat exchange tubes. Heat fins 212, a plurality of first heat exchange tubes 211 are arranged at intervals in the up and down direction, and each first heat exchange tube 211 extends in the left and right direction to sequentially pass through the plurality of heat exchange fins 212; among them, two adjacent first heat exchange tubes 211 The distance l1 between the heat pipes 211 satisfies 14mm≤l1≤25mm, each first heat exchange tube 211 extends along the second direction, and each first heat exchange tube 211 is penetrated through a plurality of heat exchange fins 212, The heat exchange fins 212 are arranged at intervals in the second direction. The distance l2 between two adjacent heat exchange fins 212 can satisfy 2mm≤l2≤10mm. Each heat exchange fin 212 extends in the first direction, which is beneficial to reduce the heat exchange fins. The wind resistance generated by 212 improves heat exchange efficiency. The outer diameter d of the first heat exchange tube 211 satisfies 4mm≤d≤7.5mm, so that the diameter of the first heat exchange tube 211 is smaller, so that the first heat exchange tube 211 is reduced on the premise of meeting the heat exchange demand. At the same time, the number of the first heat exchange tubes 211 can be appropriately increased to a certain extent; the width w of the heat exchange fins 212 in the front and rear direction satisfies 12mm≤w≤30mm, which is beneficial to reduce the wind resistance generated by the heat exchange fins 212 . When at least two of the plurality of first heat exchange tubes 211 are connected in parallel, the flow area of the heat exchange medium can be effectively increased, and the small diameter of the first heat exchange tube 211 can prevent the heat exchange medium from having a large flow resistance, thereby ensuring the exchange rate. The heat medium flows smoothly.

Wherein, a plurality of first heat exchange tubes 211 are connected in series and/or in parallel; for example, two adjacent first heat exchange tubes 211 are connected in series through an elbow (as shown in FIG. 20 and FIG. 21), and one of the first heat exchange tubes 211 is connected in series. The heat pipe 211 is formed as an inlet pipe 2111, and one first heat exchange pipe 211 is formed as an outlet pipe 2112; for another example, the plurality of first heat exchange pipes 211 includes a first group 2113 and a second group 2114, and a first group 2113 and a second group 2113. The two groups 2114 each include a plurality of first heat exchange tubes 211, the plurality of first heat exchange tubes 211 of the first group 2113 are connected in series, the plurality of first heat exchange tubes 211 of the second group 2114 are connected in series, and the first group 2113 and the first group 2113 are connected in series. The two groups 2114 are connected in parallel. The first group 2113 and the second group 2114 each have an inlet pipe 2111 and an outlet pipe 2112. The first group 2113 is located on the upper side of the second group 2114 (as shown in Figure 22 and Figure 23), or the first group 2113 and the second group 2114 have an inlet pipe 2111 and an outlet pipe 2112. The first heat exchange tubes 211 of a group 2113 and the first heat exchange tubes 211 of the second group 2114 are alternately arranged (as shown in FIGS. 24 and 25).

It is understandable that when at least two of the plurality of first heat exchange tubes 211 are connected in parallel, the flow area of the heat exchange medium can be effectively increased, and the small diameter of the first heat exchange tube 211 can be prevented from causing flow resistance of the heat exchange medium. Large, to ensure the smooth flow of the heat exchange medium.

In some embodiments as shown in Figures 48 and 50, the first heat exchange component 2 is a tube-fin heat exchanger, and the first heat exchange component 2 includes a dense fin part 23 and a sparse fin part 24. The dense fin part 23 is Two, and the two dense sheet portions 23 are respectively provided on both sides of the thin sheet portion 24 along the second direction, so that the thin sheet portion 24 is arranged corresponding to the middle of the first air inlet 101 in the second direction; the thin sheet portion 24 includes a plurality of first heat exchange fins 241 arranged at intervals in the second direction, the dense fin portion 23 includes a plurality of second heat exchange fins 211 arranged at intervals in the second direction, and two adjacent first heat exchange fins 211 are arranged at intervals in the second direction. The spacing M1 between the fins 241 is greater than the spacing M2 between the two adjacent second heat exchange fins 211, the arrangement density of the first heat exchange fins 241 may be smaller than the arrangement density of the second heat exchange fins 211, so that When the fin portion 24 is arranged corresponding to the middle portion of the first air inlet 101 in the second direction, it can effectively reduce the air inlet wind resistance of the heat exchange device 100.

For example, in the example of FIGS. 37 and 48, there are two exhaust parts 3, and the two exhaust parts 3 are respectively arranged corresponding to the two second air outlets 103, then the two dense sheet parts 23 are connected to the two exhaust parts respectively. The wind parts 3 are correspondingly arranged; in the second air outlet mode, the two exhaust parts 3 can respectively generate strong forced convection airflow on both sides of the first heat exchange part 2, and the dense sheet part 23 can be forced convectively The air flow has a larger contact area, which is beneficial to increase the heat exchange area of the first heat exchange component 2 to enhance the heat exchange effect. The sparse fin part 24 is far away from the exhaust part 3, and the sparse fin part 24 is forced to correspond to the area. The convection effect is relatively weak, which can reduce the wind resistance of the thinning part 24; in the first air outlet mode, the wind resistance of the thinning part 24 is small, which is conducive to air flow and ensures smooth air flow, thereby ensuring sufficient natural convection heat transfer , It is beneficial to strengthen the heat transfer effect of the self-heated convection of the first heat exchange component 2.

It should be noted that the distance M1 between two adjacent first heat exchange fins 241 can be understood as the minimum value of the multiple distances, that is, the distance between any two adjacent first heat exchange fins 241, respectively M1, m2,..., mn, then M1=min{m1, m2,..., mn}; the distance M2 between two adjacent second heat exchange fins 211 can be understood as the minimum value of multiple distances , That is, the distances between any two adjacent second heat exchange fins 211 are m1', m2',..., mn', then M2=min{m1', m2',..., mn'}. When the plurality of first heat exchange fins 241 are evenly spaced along the second direction, the distance between any two adjacent first heat exchange fins 241 is equal. Similarly, when the plurality of second heat exchange fins 211 are arranged along the second direction When the directions are evenly spaced, the distance between any two adjacent second heat exchange fins 211 is equal; of course, a plurality of first heat exchange fins 241 can also be arranged at non-uniform intervals, and a plurality of second heat exchange fins 211 can also be arranged at non-uniform intervals. Can be set at non-uniform intervals. For example, in the example of FIG. 48, the distance M1 between two adjacent first heat exchange fins 241 may satisfy 2mm≤M1≤10mm, and the distance M2 between two adjacent second heat exchange fins 211 may satisfy 1mm ≤M1≤2mm.

Among them, in the second direction, the length of the sparse fin portion 24 is L3, the length of the dense fin portion 23 is L4, the number of first heat exchange fins 241 is N1, and the number of second heat exchange fins 211 is N2, then the first The arrangement density of the heat exchange fins 241 is smaller than the arrangement density of the second heat exchange fins 211, which is understood as L3/(N1-1)>L4/(N2-1). In the second direction, the lengths of the dense piece portions 23 on both sides of the sparse piece portion 24 are equal or unequal; in the second direction, the length L3 of the sparse piece portion 24 and the length L4 of the dense piece portion 23 satisfy: 1 ＜L3/L4≤10.

It is understandable that the first heat exchange component 2 can be a whole, at this time, the dense sheet part 23 and the thin sheet part 24 can form the above-mentioned first heat exchange component 2 by parameters; the first heat exchange component 2 can also include multiple The heat part, a plurality of heat exchange parts can be spaced apart along the second direction, and a single heat exchange part can be formed into a dense sheet part 23 or a thin sheet part 24 to facilitate the processing of the first heat exchange part 2; the first heat exchange part 2 may also include a plurality of first heat exchange units and a plurality of second heat exchange units, the plurality of first heat exchange units are arranged at intervals to form a dense sheet part 23, and a plurality of second heat exchange units are arranged at intervals to form a sparse sheet part 24.

In some other embodiments, the dense sheet portion 23 and the thin sheet portion 24 are respectively one, and the dense sheet portion 23 and the thin sheet portion 24 are arranged along the second direction, the exhaust member 3 is one, and the exhaust member 3 is arranged at The first heat exchange component 2 corresponds to one side of the dense sheet portion 23.

In still other embodiments, as shown in FIG. 40, the air duct 9 on the downstream side of the first heat exchange component 2 is provided with an air guide mechanism 9 which divides the air duct on the downstream side of the first heat exchange component 2 into multiple A plurality of sub-air ducts are arranged in sequence along the second direction, and the plurality of sub-air ducts are respectively corresponding to the sparse sheet portion 24 and the dense sheet portion 23. The thin sheet portion 24 corresponds to one sub-air channel, and the dense sheet portion corresponds to one sub-air channel. Air duct; when the exhaust component 3 is working, a larger air volume flows from the dense sheet part 23 to the corresponding sub-air channel, and a smaller air volume flows from the sparse sheet part 24 to the corresponding sub-air channel, which is beneficial to further enhance the forced air heat exchange effect. Wherein, the downstream side air passage may be defined by the first heat exchange component 2 and the inner wall surface of the housing 1.

In the example of FIG. 40, the air guide mechanism 9 includes at least one guide plate assembly, the guide plate assembly includes at least one guide plate 91, and the guide plate 91 extends in the third direction. In the second direction, the guide plate assembly is located in the sheet-splitting component. 22 and the dense sheet part 23; when there are multiple guide plate assemblies, the plurality of guide plate assemblies are arranged at intervals along the second direction. For example, the guide plate assembly includes two guide plates 91, and the two guide plates 91 of the guide plate assembly are along the Arranged in the first direction. Wherein, in the third direction, the width of the guide plate 91 is half of the width of the downstream side air duct, and the position of the guide plate 91 in the third direction relative to the first heat exchange component 2 can be specifically set according to actual applications.

In addition, in some embodiments, the housing 1 is also provided with a second heat exchange component 4, the second heat exchange component 4 is a tube-fin heat exchanger, and the arrangement of the heat exchange fins of the second heat exchange component 4 is dense and dense. The rule is the same as that of the first heat exchange component 2, which can simplify the design of the heat exchange device 100; or the arrangement of the heat exchange fins of the second heat exchange component 4 is different from that of the first heat exchange component 2. In other embodiments, the second heat exchange component 4 is another type of heat exchanger, such as an inflation heat exchanger.

As shown in FIG. 48, in some embodiments, the width W1 of the first heat exchange fin 241 in the third direction is greater than the width W2 of the second heat exchange fin 211 in the third direction. The width W1 of the fin 241 is greater than the width W2 of the second heat exchange fin 211. Therefore, since the wind resistance of the sparse fin portion 24 is small, the width of the first heat exchange fin 241 of the sparse fin portion 24 is relatively large, which can effectively increase the heat exchange area between the first heat exchange component 2 and the air, which is beneficial to the first heat exchange area. A heat exchange fin 241 better exchanges heat with the air, and enhances the effect of natural convection heat exchange.

Of course, in other embodiments of the present application, W1 can also be equal to W2, as shown in FIG. 49.

Among them, the axis of the cross flow fan 30 can be understood as the rotation axis of the cross flow fan 30. Wherein, the number of cross-flow fans 30 and the number of second air outlets 103 are equal or not equal.

Of course, the present application is not limited to this. In some other embodiments, the exhaust component 3 is other types of fans, and the number and arrangement of the fans can be specifically set according to actual needs.

For example, in the first air outlet mode, the air in the housing 1 exchanges heat with the first heat exchange component 2, and the heat exchanged air can flow in the first direction to the first air outlet 102 and pass through the first air outlet. 102 is discharged, negative pressure can be formed at the first air inlet 101, and the air outside the housing 1 can flow into the housing 1 through the first air inlet 101, and then exchange heat with the first heat exchange component 2. Therefore, in the first air outlet mode, since the exhaust component 3 does not work, the heat exchange device 100 can be operated without noise, and the air and the first heat exchange component 2 can transfer heat through natural convection to realize the heat exchange device 100 Therefore, the first air outlet mode of the heat exchange device 100 can be applied to light-load application scenarios such as sleep.

In the second air outlet mode, the exhaust component 3 works to generate negative pressure at the first air inlet 101, and the air outside the shell 1 can flow into the shell 1 through the first air inlet 101 to exchange heat with the first air inlet 101. Component 2 exchanges heat. Since the exhaust component 3 is located on the side of the first heat exchange component 2 close to the second air outlet 103, under the driving action of the exhaust component 3, the heat exchanged air can pass through the second air outlet 103 is discharged.

In an embodiment of the present application, as shown in Figure 55, Figure 56, Figure 59 and Figure 60, the heat exchange device 100 includes a housing assembly 1 and a heat exchange component 2, and the housing assembly 1 includes a first housing 11 and The second housing 12, the first housing 11 has a first vent 111, the second housing 12 has a second vent 121, and the second housing 12 penetrates the first housing 11 in the vertical direction, and The union of the inner cavity of the second housing 12 and the inner cavity of the first housing 11 defines a ventilation chamber 10.

For example, the inner cavity of the first housing 11 is the first cavity 110, the inner cavity of the second housing 12 is the second cavity 120, and the first vent 111 penetrates the first housing along the thickness direction of the first housing 11. Body 11, and the first vent 111 communicates with the first chamber 110, the inside of the first chamber 110 communicates with the outside of the first chamber 110 through the first vent 111; the second vent 121 is along the second housing 12 The thickness direction penetrates the second housing 12, and the second vent 121 communicates with the second chamber 120, and the inside of the second chamber 120 communicates with the outside of the second chamber 120 through the second vent 121. When the second housing 12 passes through the first housing 11 in the vertical direction, at least part of the first housing 11 is sleeved on the second housing 12, and at least a part of the second housing 12 is located in the first chamber 110 , The first chamber 110 is in communication with the second chamber 120, and the union of the first chamber 110 and the second chamber 120 forms the ventilation chamber 10, that is, the first chamber 110 and the second chamber 120 are combined The cavity formed together is the ventilation cavity 10. Wherein, the heat exchange component 2 is provided in the ventilation chamber 10, and the air in the ventilation chamber 10 can exchange heat with the heat exchange component 2. In some embodiments, the first vent 111 is formed as an air inlet, and the second vent 121 is formed as an air outlet. The first vent 111 and the second vent 121 are communicated through the ventilation chamber 10, and the outside of the housing assembly 1 The air flows into the ventilating chamber 10 through the first vent 111 and exchanges heat with the heat exchange component 2. The heat exchanged air is discharged through the second vent 121 to achieve cooling or heating of the heat exchange device 100.

In the embodiment shown in FIG. 64, the heat exchange device 100 further includes a driving mechanism 3, which drives one of the first housing 11 and the second housing 12 to move up and down relative to the other to adjust the ventilation cavity. Room 10. The driving mechanism 3 drives the first housing 11 to move up and down relative to the second housing 12. At this time, the first chamber 110 moves up and down relative to the second chamber 120, or the drive mechanism 3 drives the second housing 12 Move in the up and down direction relative to the first housing 11, at this time the second chamber 120 moves in the up and down direction relative to the first chamber 110, wherein the drive mechanism 3 drives the first housing 11 and the second housing 12 During the above-mentioned movement in the up and down direction, as the relative positions of the first chamber 110 and the second chamber 120 change, the union of the first chamber 110 and the second chamber 120 changes, thereby adjusting the ventilation chamber The size of the volume 10, for example, the volume of the ventilation chamber 10 can be increased to ensure that the ventilation chamber 10 has enough space to achieve the convergence of the air after heat exchange. At the same time, the ventilation cavity can be reduced when the heat exchange device 100 is not working. The volume of the chamber 10 saves the space occupied by the heat exchange device 100, and facilitates movement and storage.

At the same time, when the driving mechanism 3 drives the above-mentioned one of the first housing 11 and the second housing 12 to move, the vents on the first housing 11 or the second housing 12 (for example, the first vent 111 or The second vent 121) moves in the up-and-down direction to adjust the height of the above-mentioned vent, so that when the vent is used as an air outlet, it is convenient to make the vent have a suitable air outlet height, which is beneficial to improve the user's comfort and convenience The air outlet height is matched with the operation mode of the heat exchange device 100. For example, when the heat exchange device 100 is used for cooling, the air outlet height can be increased, and when the heat exchange device 100 is used for heating, the air outlet height can be reduced.

The heat exchanged air converges in the ventilation chamber 10 and spontaneously flows to the second vent 121 to be discharged through the second vent 121 to achieve the exchange Cooling or heating of the heating device 100. At the same time, a negative pressure is formed at the first vent 111, and the air outside the housing assembly 1 flows into the ventilating chamber 10 through the first vent 111, and then exchanges heat with the heat exchange component 2. Therefore, the heat exchange device 100 can achieve noiseless operation during the above-mentioned working process, and has good sound quality, and the air and the heat exchange component 2 can transfer heat through natural convection, so that the air output of the heat exchange device 100 is soft and can be The windlessness of the heat exchange device 100 is realized, so that the heat exchange device 100 can be suitable for light load application scenarios such as sleep.

Of course, in other examples, the first vent 111 is formed as an air outlet, and the second vent 121 is formed as an air inlet.

The drive mechanism 31 is provided in the first housing 11, and the transmission mechanism 32 is connected to the drive motor 31 and the second housing. Between the housings 12, the transmission mechanism 32 is formed as a rack and pinion transmission mechanism, and the transmission mechanism 32 includes a gear 321 and a rack 322 that mesh and cooperate. The gear 321 is connected to the motor shaft of the driving motor 31, and the rack 322 is provided in the second rack. In the housing 12, the rack 322 extends in the up and down direction, and the driving motor 31 drives the gear 321 to rotate, driving the rack 322 to move in the up and down direction, thereby driving the second housing 12 to move in the up and down direction relative to the first housing 11. Therefore, the driving mechanism 3 has a simple structure and is easy to implement.

Of course, in other examples, the transmission mechanism 32 is formed as a ball screw mechanism. The transmission mechanism 32 includes a nut and a screw. The nut is provided in the second housing 12. The screw extends in the up and down direction and is connected to the drive motor 31 to be connected to the drive motor 31. The driving motor 31 drives to rotate, and during the rotation of the screw, the nut moves along the extending direction of the screw, which also realizes the movement of the second housing 12 relative to the first housing 11; but it is not limited to this.

In the following description of the present application, the first vent 111 is an air inlet and the second vent 121 is an air outlet as an example. After reading the technical solutions of the present application, those skilled in the art can use the first vent 111 as an air outlet and the second vent 121 as an air inlet.

In some embodiments, as shown in FIGS. 56 and 60, the driving mechanism 3 drives the second housing 12 to move up and down relative to the first housing 11, and the heat exchange component 2 and the first housing 11 are relatively stationary. It is beneficial to reduce the load of the drive mechanism 3 and reduce the power consumption of the drive mechanism 3. At the same time, since the first housing 11 penetrates the second housing 12, at least part of the first housing 11 is sleeved on the second housing 12. , So that the heat exchange device 100 can be easily installed and fixed by the first housing 11, for example, the first housing 11 is hung on a wall to realize the installation of the heat exchange device 100.

Of course, in other embodiments, the driving mechanism 3 drives the first housing 11 to move in the up and down direction relative to the second housing 12, and the heat exchange component 2 and the second housing 12 are relatively stationary; The way in which the mechanism 3 drives the first housing 11 to move, and the way in which the drive mechanism 3 drives the second housing 12 to move facilitates the installation and implementation of the heat exchange device 100, and weakens the restriction on the movement range of the second housing 12. The applicability of the heat exchange device 100 is improved.

As shown in Figure 56, Figure 60, Figure 61 and Figure 63, the first housing 11 has an escape opening 114, the escape opening 114 penetrates the first housing 11 along the thickness direction of the first housing 11, and the escape opening 114 is connected to the The first chamber 110 is in communication; the second housing 12 has an escape slot 123 extending in the up and down direction, the escape slot 123 penetrates the second housing 12 along the thickness direction of the second housing 12, and the escape slot 123 is connected to the The second chamber 120 communicates with each other. The refrigerant pipe 4 connected to the heat exchange component 2 passes through the avoidance slot 123 and the escape opening 114, and one end of the refrigerant pipe 4 is connected to the heat exchange component 2, and the other end of the refrigerant pipe 4 passes through the avoidance slot 123 and the escape opening 114 in turn. The opening 114 extends to the outside of the housing assembly 1. Since the heat exchange component 2 and the first housing 11 are relatively stationary, the refrigerant pipe 4 and the avoiding opening 114 are relatively stationary, and the driving mechanism 3 drives the second housing 12 to be relatively stationary. During the movement of the casing 11 in the up and down direction, the avoiding slot 123 moves in the up and down direction relative to the refrigerant pipe 4 to avoid the refrigerant pipe 4 to ensure the reliable use of the refrigerant pipe 4 and realize the smooth movement of the second housing 12.

In the example of Figure 61 and Figure 64, the heat exchange component 2 has an inlet and an outlet, and the inlet and the outlet are respectively connected with refrigerant pipes 4; when the inlet and outlet are one each, there are two refrigerant pipes 4, and two refrigerant pipes 4 are the refrigerant inlet pipe 41 and the refrigerant outlet pipe 42, respectively. The refrigerant inlet pipe 41 is connected to the inlet, and the refrigerant outlet pipe 42 is connected to the outlet. The refrigerant inlet pipe 41 and the refrigerant outlet pipe 42 are both penetrated through the escape slot 123 and the escape opening 114 ; At this time, the number of avoidance openings 114 is one or more. When the number of avoidance openings 114 is one, the refrigerant inlet pipe 41 and the refrigerant outlet pipe 42 pass through the same avoidance opening 114. When the number of avoidance openings 114 is multiple, the refrigerant inlet pipe 41 and the refrigerant outlet pipe 42 are respectively penetrated through different escape openings 114.

In other examples, at least one of the inlet and the outlet of the heat exchange component 2 is provided in multiples, and at this time, the number of avoiding openings 114 is one or more.

In some embodiments, as shown in FIGS. 56 and 60, the avoiding slot 123 and the avoiding opening 114 are both located on the side of the housing assembly 1 in the left-right direction, and the avoiding slot 123 is located at the left and right of the second housing 12. On the side in the direction, the escape opening 114 is located on the side of the first housing 11 in the left-right direction. Therefore, the avoidance slot 123 and the avoidance opening 114 are arranged reasonably, which effectively ensures the smoothness of the movement of the second housing 12.

For example, in the examples of FIGS. 60 and 61, the escape opening 114 is formed on the side wall of the first housing 11 in the left and right direction, and the escape slot 123 is formed on the side wall of the second housing 12 in the left and right direction. , And the avoiding opening 114 and the avoiding slot 123 are located on the same side of the housing assembly 1, which facilitates the arrangement of the refrigerant pipe 4.

As shown in FIGS. 56 and 60, the avoiding slot 123 penetrates at least one end of the second housing 12 in the vertical direction along the vertical direction, which is beneficial to weaken the restriction on the movement range of the second housing 12. For example, if the avoiding slot 123 penetrates the upper end of the second housing 12 in the up and down direction to form a slot 1230, and the avoiding slot 123 does not penetrate the lower end of the second housing 12, the refrigerant pipe 4 can enter and exit the avoiding slot through the slot 1230. 123. It facilitates the installation of the refrigerant pipe 4, and at the same time, the second housing 12 can move downward to the position where the refrigerant pipe 4 and the escape slot 123 are out of cooperation, which weakens the restriction on the movement range of the second housing 12; In some examples, the avoiding slot 123 penetrates the lower end of the second housing 12 in the up and down direction to form a slot 1230; in some examples, the avoiding slot 123 penetrates the upper and lower ends of the second housing 12 in the up and down direction, respectively.

In some embodiments, as shown in FIG. 58, the height H2 of the second housing 12 in the vertical direction is less than or equal to the height H1 of the first housing 11 in the vertical direction, so that when the heat exchange device 100 is not working, the first At least part of the second housing 12 can be contained in the first chamber 110, which saves the space occupied by the heat exchange device 100 and facilitates storage. At this time, at least most of the outer surface of the housing assembly 1 is covered by the first housing 11 The outer surface is formed to facilitate shielding and sealing of the vents (such as the first vent 111) on the wall of the housing assembly 1 to prevent dust from entering the housing assembly 1, to ensure the cleanliness of the heat exchange device 100, and to facilitate the heat exchange device 100 Maintenance.

Wherein, the height H2 of the second housing 12 in the up and down direction and the height H1 of the first housing 11 in the up and down direction satisfy 1≤H1/H2<6, so that the ventilation chamber 10 has a larger adjustment range, It is convenient to further ensure that the ventilating chamber 10 has enough space to achieve air gathering and enhance the spontaneous flow effect of air.

In the example of FIGS. 55 and 58, the height H1' of the first chamber 110 in the up-down direction is less than or equal to the height H1 of the first housing 11 in the up-down direction, and the height H2 of the second housing 12 in the up-down direction If the height H1 ′ of the first chamber 110 in the vertical direction is less than or equal to, the second housing 12 can be completely contained in the first chamber 110 to save the storage space of the heat exchange device 100.

In some embodiments, as shown in FIGS. 59 and 63, the heat exchange component 2 and the first housing 11 are relatively stationary, and at least part of the heat exchange component 2 is disposed in the first chamber 110, and the heat exchange component 2 The orthographic projection along the front-rear direction falls within the orthographic projection of the first housing 11 along the front-rear direction, that is, on a plane perpendicular to the front-rear direction, the orthographic projection of the heat exchange component 2 falls within the orthographic projection of the first housing 11, The first vent 111 is arranged opposite to the heat exchange component 2 in the front-to-rear direction.

In the example of FIG. 59, the first vent 111 is formed on the front wall surface of the first housing 11, the first vent 111 is formed as an air inlet, and the airflow flows from the front to the back through the first vent 111 to the ventilation chamber 10. The second housing 12 moves up and down relative to the first housing 11, so that the second vent 121 can move to Below or above the first vent 111.

For example, when the heat exchange device 100 is used for cooling, the second housing 12 moves up and down relative to the first housing 11, so that the second vent 121 moves below the first vent 111, and the cold air after heat exchange Converged in the ventilation chamber 10, due to the low temperature and high density of the cold air, the cold air sinks spontaneously and is discharged through the second vent 121 to achieve the air out of the heat exchange device 100. When the heat exchange device 100 is used During heating, the second housing 12 moves up and down relative to the first housing 11, so that the second vent 121 moves below the first vent 111, and the cold air after heat exchange is collected in the ventilation chamber 10 Since the hot air has a higher temperature and a lower density, the hot air rises spontaneously and is discharged through the second vent 121 to achieve air out of the heat exchange device 100.

As shown in Figure 58 and Figure 62, when the drive mechanism drives the second housing 12 to move up and down relative to the first housing 11, and the heat exchange component and the first housing 11 are relatively stationary, the first housing 11 moves in the up and down direction. One end of the upper part is opened as an opening 113, and the second housing 12 moves up and down relative to the first housing 11 through the opening 113, that is, at least part of the second housing 12 can be moved out of the first housing 11 through the opening 113, Thus, the smooth movement of the second housing 12 is ensured, and the relative movement range of the first housing 11 and the second housing 12 is ensured.

The end of the first housing 11 in the up-down direction away from the opening 113 also has a third vent 112. By providing the third vent 112, when the third vent 112 is used as an air inlet, the air intake and heat exchange can be increased. effect. For example, in the example shown in FIGS. 58 and 62, the third vent 112 is formed at the upper end of the first housing 11 for air intake, the opening 113 is formed at the lower end of the first housing 11, and the second housing 11 is 12 passes through the first housing 11 through the opening 113, and the second housing 12 moves in the vertical direction relative to the first housing 11 through the opening 113. When the heat exchange device 100 is used for cooling, the second housing 12 moves relative to the first housing 11 so that the second vent 121 moves below the first vent 111, and the cold formed by the heat exchange with the heat exchange component 2 The air sinks spontaneously and is discharged through the second vent 121.

In other examples, the third vent 112 is formed at the lower end of the first housing 11 for air intake, the opening 113 is formed at the upper end of the first housing 11, and the second housing 12 is penetrated through the opening 113.

When the third vent 112 is formed at the upper end of the first housing 11, in some examples, the third vent 112 is formed on the top wall of the first housing 11; in other examples, the second vent 121 It is formed on the front wall of the upper end of the first housing 11; in still other examples, the third vent 112 is formed on the side wall (for example, the left side wall and/or the right side wall) of the upper end of the first housing 11.

In some embodiments, as shown in FIGS. 58 and 62, the second vent 121 is formed at the upper or lower end of the second housing 12, which reduces the number of changes in the air flow direction after heat exchange to a certain extent. On the premise that the converging space of the heated air is fixed, it is convenient to ensure that the air outlet parameters of the second vent 121 meet the requirements and improve the comfort of the user. At the same time, under the premise that the heat exchange device 100 occupies a certain space, it is convenient for the heat exchange. The air provides a larger gathering space, which is conducive to the spontaneous flow of air.

As shown in FIGS. 58 and 62, the second vent 121 is formed at the lower end of the second housing 12, and the second housing 12 moves downward relative to the first housing 11, so that the second vent 121 is located at the first vent. Below 111, the ventilation chamber 10 has enough space. When the heat exchange device 100 is used for cooling, the ventilation chamber 10 provides a larger gathering space for the cold air after heat exchange, which is beneficial to enhance the spontaneous release of cold air. Shen effect. Among them, in some examples, the second vent 121 is formed on the bottom wall of the second housing 12; in other examples, the second vent 121 is formed on the front wall of the lower end of the second housing 12; In an example, the second vent 121 is formed on the side wall (for example, the left side wall and/or the right side wall) of the lower end of the second housing 12.

In other examples, the second vent 121 is formed at the upper end of the second housing 12, and the second housing 12 moves upward relative to the first housing 11, so that the second vent 121 is located above the first vent 111, Therefore, the ventilation chamber 10 has enough space. When the heat exchange device 100 is used for heating, the ventilation chamber 10 provides a larger gathering space for the hot air after heat exchange, which is beneficial to enhance the spontaneous rise effect of the hot air. Among them, in some examples, the second vent 121 is formed on the top wall of the second housing 12; in other examples, the second vent 121 is formed on the front wall of the upper end of the second housing 12; In an example, the second vent 121 is formed on the side wall (for example, the left side wall and/or the right side wall) of the upper end of the second housing 12.

In some embodiments, as shown in FIGS. 58 and 62, one end of the first housing 11 in the up-down direction has a third vent 112, and the other end of the first housing 11 in the up-down direction is opened as an opening 113. , The second housing 12 is moved up and down relative to the first housing 11 by the third vent 112 and the opening 113, then the second housing 12 is penetrated into the first housing 11 by the third vent 112, the second The housing 12 moves in the up and down direction relative to the first housing 11 through the third vent 112, and the second housing 12 has an opening 113 through the first housing 11, and the second housing 12 is opposite to the first housing 11 through the opening 113. A housing 11 moves in the up and down direction. Thus, the smooth movement of the second housing 12 is ensured, and at the same time, the first housing 11 does not need to open additional vents, and instead of using only the second vent 121 to discharge air, the third vent 112 is provided. When 112 is used as a tuyere, when the heat exchange device 100 needs to meet the same temperature adjustment requirements, it is beneficial to reduce the relative movement range of the first shell 11 and the second shell 12, save the space occupied by the heat exchange device 100, and facilitate The setting of the drive mechanism 3.

The other end of the second housing 12 in the vertical direction (that is, the end far from the second vent 121) is formed with a fourth vent 122, and the fourth vent 122 is in communication with the second chamber 120, which is beneficial to ensure the heat exchange device 100 The spontaneous air flow effect during cooling and heating. In some examples, the second vent 121 is formed at the lower end of the second housing 12, and the fourth vent 122 is formed at the upper end of the second housing 12; in other examples, the second vent 121 is formed at the second At the upper end of the casing 12, a fourth vent 122 is formed at the lower end of the second casing 12.

This facilitates the setting of the housing assembly 1, and further ensures that the ventilation chamber 100 has enough space to achieve air gathering, and is beneficial to the heat exchange device 100 to meet the differentiated needs of different users and different indoor environments, and has a good Practicality and applicability.

It is understandable that when the heat exchange device 100 is used for cooling, the distance between the second vent 121 and the first vent 111 can be adjusted according to actual needs, and the distance between the first housing 11 and the second housing 12 The mating length can be adjusted according to actual requirements; similarly, when the heat exchange device 100 is used for heating, the distance between the fourth vent 122 and the first vent 111 can be adjusted according to actual requirements, then the first housing 11 and The mating length between the second shells 12 can be adjusted according to actual needs.

The door 6 is used to open and close the opening 113. For example, the first opening and closing door 5 is movably arranged at the third vent 112, and the first opening and closing door 5 moves between an open position and a closed position. In the open position, the first opening and closing door 5 opens the third vent 112, In the closed position, the first opening and closing door 5 closes the third vent 112; the second opening and closing door 6 is movably arranged at the opening 113, and the second opening and closing door 6 moves between the open position and the closed position. In the open position, The second opening and closing door 6 opens the opening 113, and in the closed position, the second opening and closing door 6 closes the opening 113. Wherein, the movement modes of the first opening and closing door 5 and the second opening and closing door 6 are not specifically limited here, for example, the first opening and closing door 5 and the second opening and closing door 6 can move and/or rotate relative to the first housing 11.

At this time, the first open and close door 5 The third vent 122 is closed to strengthen the cooling air and prevent the heat exchange device 100 from leaking through the third vent 122; in the example shown in FIGS. 11 and 12, when the heat exchange device 100 is used for heating, the first A door 5 opens the third vent 122, and the second housing 12 moves relative to the first housing 11 through the third vent 122, so that the fourth vent 122 moves above the first vent 111 to exchange heat with The hot air formed after the heat exchange of the component 2 rises spontaneously and is discharged through the fourth vent 122. At this time, the second opening and closing door 6 closes the opening 113 to strengthen the heating air and prevent the heat exchange device 100 from leaking through the opening 113 .

The first heat exchange component of the present application is applied to heat exchange devices with different air volumes at different positions, that is, the first heat exchange component has different heat exchange capabilities for different positions. The first heat exchange component of the present application is composed of a plurality of first heat exchange tubes and heat exchange fin groups, and the heat exchange fin groups are sleeved on the first heat exchange tubes. The heat exchange fin group is divided into a first heat exchange zone and a second heat exchange zone. The first heat exchange zone is provided with a plurality of first heat exchange fins, and the second heat exchange zone is provided with a plurality of second heat exchange fins. The heat exchange fins and the second heat exchange fins are arranged such that the heat exchange capacity of the second heat exchange zone is greater than the heat exchange capacity of the first heat exchange zone. That is, for the same area of the air inlet area, the total surface area formed by the multiple second heat exchange fins is larger than the total surface area formed by the multiple first heat exchange fins. Specifically, the two embodiments shown in Fig. 67 and Fig. 69 are taken as examples for description. The specific arrangement of the first heat exchange fins and the second heat exchange fins is not limited to the two ways of FIG. 67 and FIG. 69, and other conceivable structural designs that meet the above principles are within the scope described in this application.

Referring to FIG. 67 and FIG. 68, the first heat exchange component 2 of this embodiment includes a plurality of first heat exchange tubes 21 and heat exchange fin groups.

Wherein, the plurality of first heat exchange tubes 11 are arranged side by side and spaced apart from each other along the first spacing direction Y. Two adjacent first heat exchange tubes 11 are connected to each other, and the whole is arranged in an S-shape. The first heat exchange tube 11 specifically adopts a copper tube, because copper has a higher heat exchange efficiency. The diameter of the copper tube is 3mm-10mm, and specifically can be 3mm, 5mm, 7mm, 10mm, etc.

The heat exchange fin group is divided into a first heat exchange area 22 and a second heat exchange area 23 along the first spacing direction Y. A plurality of first heat exchange fins 221 are arranged in the first heat exchange zone 22, and a plurality of second heat exchange fins 231 are arranged in the second heat exchange zone 23; The design of the fins 231 makes the heat exchange capacity of the second heat exchange zone 23 greater than that of the first heat exchange zone 22. Therefore, it is suitable for heat exchange devices with different air volumes at different positions.

Specifically, in this embodiment, the plurality of first heat exchange fins 221 are arranged at intervals along the second interval direction X, the second interval direction X crosses the first interval direction Y, and is nested in the first heat exchange zone 22 The first heat exchange tube 21. The plurality of second heat exchange fins 231 are arranged at intervals along the second spacing direction X, and are sleeved on the first heat exchange tube 21 in the second heat exchange zone 23. Further, the first spacing direction Y and the second spacing direction X are perpendicular to each other.

The first heat exchange area 22 is defined by the edges of the plurality of first heat exchange fins 221, and the second heat exchange area 23 is defined by the edges of the plurality of second heat exchange fins 231. The shape formed by the edge is the shape of the heat exchange area.

Corresponding to the square air inlet area, the entire heat exchange fin group in this embodiment is also square, and the upper edges of the first heat exchange fins 221 and the lower edges of the second heat exchange fins 231 are arranged flush. For other shapes of the air inlet area, heat exchange fin groups of corresponding shapes can also be provided. In order to facilitate production, the multiple first heat exchange fins 221 all adopt the same design, and the multiple second heat exchange fins 231 also adopt the same design. That is, the lower edge of the first heat exchange fin 221 and the upper edge of the second heat exchange fin 231 are also arranged flush.

In this embodiment, the first heat exchange area 22 corresponds to the first air inlet area 111, and the second heat exchange area 23 corresponds to the second air inlet area 112. For the same area of the air inlet area, for example, for the same area of the second air inlet area. The partial area 1111 in the wind zone 112 and the first air inlet zone 111 corresponds to a total surface area of the second heat exchange fins 231 which is greater than the total surface area of the first heat exchange fins 221.

Specifically, the first heat exchange fins 221 have a first width W1 along the vertical direction Z of the first spacing direction Y and the second spacing direction X, and the second heat exchange fins 231 have a second width W2 along the vertical direction Z. Wherein, the second width W2 is greater than the first width W1.

Since the plurality of first heat exchange fins 221 may have different designs, and the plurality of second heat exchange fins 231 may also have different designs, the above-mentioned first width W1 may be the average first width, and the second width W2 may be the average second width. width. If the second width W2 is too large, it will cause a certain resistance to the wind flow. Therefore, in this embodiment, the second width W2 is 5%-70% larger than the first width W1.

This embodiment is specifically applied to an indoor unit that achieves cooling and cooling by natural convection. The cold air settles from the first heat exchange zone 22 to the second heat exchange zone 23. Therefore, a larger air volume will be formed in the second heat exchange zone 23. The heat exchange capacity of the second heat exchange zone 23 is relatively high. Generally speaking, the lower 5%-40% of the entire heat exchange zone will have an increase in air volume. Therefore, the first heat exchange zone 22 and the second heat exchange zone 23 are also correspondingly designed.

The first heat exchange area 22 has a first height H1 in the first interval direction Y, and the second heat exchange area 23 has a second height H2 in the first interval direction Y. The second height H2 occupies the first height H1 and the second height H2. 5%-40% of the sum of height H2, that is, H2=(5%-40%)×(H1+H2). If the first heat exchange zone 22 and the second heat exchange zone 23 have multiple heights, the average height shall prevail.

In addition, in this embodiment, the first heat exchange area 22 and the second heat exchange area 23 are arranged at intervals, and the separation distance G between the two heat exchange areas is less than or equal to 5 mm. Wherein, the edges of the plurality of first heat exchange fins 121 constitute the edges of the first heat exchange zone 22, the edges of the plurality of second heat exchange fins 231 constitute the edges of the second heat exchange zone 23, and the lower edge of the first heat exchange zone 22 The distance from the upper edge of the second heat exchange zone 23 is the separation distance; further, if the distance between the lower edge of the first heat exchange zone 22 and the upper edge of the second heat exchange zone 23 is not unique, then The average spacing is the separation distance.

Further, in heat exchange applications, when the first heat exchange area 22 and the second heat exchange area 23 are vertically arranged from top to bottom, the condensed water on the heat exchange fins will drip from the second heat exchange fins 231, so the indoor In the machine, there will be a water collection trough under the second heat exchange fin 231. The width of the water collection trough needs to be greater than the width of the bottom edge 2311 of the second heat exchange fin 231. A too wide water collection trough will affect the discharge flow rate of the settled cold air. Therefore, In this embodiment, the width of the bottom edge 2311 of the second heat exchange fin 231 is reduced.

A beveled edge 2313 is provided between the bottom edge 2311 of the second heat exchange fin 231 away from the first heat exchange fin 221 and the side edge 2312 along the first spacing direction Y to form a diversion angle. The condensed water flows from the diversion angle to the bottom edge 2311 and finally drips into the sump. The angle θ of the diversion angle is set to 95°-175°. In this embodiment, the width W21 of the bottom edge 2311 of the second heat exchange fin 231 is 2 mm-45 mm.

The width W2 of the first heat exchange fin 221 is 5mm-50mm, and the thickness T1 along the X direction is 0.01mm-0.5mm. The thickness T2 of the second heat exchange fin along the X direction can also be 0.01mm-0.5mm. In order to ensure heat exchange efficiency and prevent the first heat exchange component from obstructing the air in the direction of wind flow, the distance between two adjacent first heat exchange fins 221 is 1mm-10mm, and the distance between two adjacent second heat exchange fins 231 The distance between them can also be set to 1mm-10mm.

In this embodiment, the width of the second heat exchange fin is increased to increase the heat exchange capacity of the second heat exchange zone. In the embodiment shown in Figure 69, another method is used to increase the heat exchange of the second heat exchange zone. ability.

For details, please refer to FIGS. 69-71. In the first heat exchange component 2 of this embodiment, a different method is adopted to realize that the heat exchange capacity of the second heat exchange zone 23 is greater than the heat exchange capacity of the first heat exchange zone 22.

The method adopted in this embodiment is that the widths of the first heat exchange fins 221 and the second heat exchange fins 231 in the vertical direction Z are the same, and the average setting density of the second heat exchange fins 231 is greater than that of the first heat exchange fins 221. Set the density. Then, for the air inlet area of the same area, the total surface area formed by the plurality of second heat exchange fins 231 is greater than the total surface area formed by the plurality of first heat exchange fins 221. That is, it is realized that the heat exchange capacity of the second heat exchange zone 23 is greater than the heat exchange capacity of the first heat exchange zone 22.

In this embodiment, part of the second heat exchange fins 231 and the first heat exchange fins 221 are integrally arranged, which is more conducive to reducing air flow resistance, because the average installation density of the second heat exchange fins 231 is greater than that of the first heat exchange fins 221 Therefore, the second heat exchange fins 231 may be staggered from the first heat exchange fins 221. In some applications, when the cold air settles from the first heat exchange zone 22 to the second heat exchange zone At 23 o'clock, the staggered second heat exchange fins 231 will affect the flow of cold air, so try to integrate the first heat exchange fins 221 and the second heat exchange fins 231 to reduce air flow resistance.

Specifically, two adjacent second heat exchange fins 231 integrally provided with the first heat exchange fin 221 include at least one second heat exchange fin 231 that is not integrally provided with the first heat exchange fin 221.
