Detailed Description

Fig. 1 is a schematic diagram of a portion of a liquid-cooled auxiliary heat dissipation system according to the related art. Referring to fig. 1, the related art liquid cooling-assisted heat dissipation system may include a guide case 910, the guide case 910 may have a first opening 911 and a second opening 912 communicating with an inner cavity thereof, a fan 930 may be disposed in the guide case 910, and a heat exchanger 940, a main board 950, a heat generating device 960, and a heat dissipating member 970 may be disposed in the inner cavity of the guide case 910, wherein the heat dissipating member 970 may be adhered to a surface of the heat generating device 960 through a heat conductive interface material and may contact the heat generating device 960 to transfer heat. The open arrows in fig. 1 indicate the direction of air flow, and referring to fig. 1, the fan 930 may direct air into the interior cavity of the guide housing 910 through the first opening 911 and out of the guide housing 910 through the second opening 912 after passing through the heat exchanger 940. The heat of the heat exchanger 940 and the heat in the inner cavity of the guide case 910 may be taken away from the inner cavity of the guide case 910 along with the flow of the air, so that the temperature of the heat exchanger 940 and the inner cavity of the guide case 910 is reduced, thereby reducing the temperature of the cooling medium flowing in the pipeline of the heat exchanger 940, thereby reducing the temperature of the heat dissipation element 970 forming a circulation loop with the heat exchanger 940 through the pipeline 920 and the water pump 980, thereby reducing the temperature of the heat generation element 960 on the motherboard 950 in contact with the heat dissipation element 970 for heat transfer.

It can be appreciated that the heat dissipation capacity of the above-mentioned liquid-cooled auxiliary heat dissipation system is related to the heat exchange efficiency of the heat exchanger 940, and the heat exchange efficiency of the heat exchanger 940 is related to the heat exchange area of the heat exchanger 940. The higher the heat exchange area of the heat exchanger 940, the higher the heat exchange efficiency of the heat exchanger 940, and the higher the heat radiation efficiency of the cold plate to the heating element.

Referring to fig. 1, in order to obtain a large heat exchange area, the outer edge of the heat exchanger 940 is often abutted against the inner wall surface of the guide case 910, i.e., the heat exchange area of the heat exchanger 940 is equal to the cross-sectional area of the inner cavity of the guide case 910. The axis of the heat exchanger 940 and the axis of the guide shell 910 are both parallel to the air flow direction (the direction of the hollow arrow in fig. 1), the heat exchange surface of the heat exchanger 940 can be obtained by cutting the heat exchanger 940 at a plane perpendicular to the axis of the heat exchanger 940, and the cross section of the inner cavity of the guide shell 910 can be obtained by cutting the guide shell 910 at a plane perpendicular to the axis of the guide shell 910.

However, with the above arrangement of the heat exchanger 940 and the guide shell 910, the heat exchange area of the heat exchanger 940 is limited by the inner cavity area of the guide shell 910, resulting in low heat dissipation of the liquid cooling auxiliary system of the related art.

To above-mentioned technical problem, this application embodiment provides a computing equipment, through set up the heat transfer group in the heat transfer chamber of casing, the heat transfer group includes a plurality of heat exchangers, and a plurality of heat exchangers are arranged in the inner chamber of casing along predetermineeing the direction, and the heat transfer area sum of a plurality of heat exchangers is greater than the cross-sectional area in the heat transfer chamber of casing, and then promotes the heat transfer total area of heat transfer group under the heat transfer chamber of limited size's casing, and then improves the radiating efficiency of equipment.

A heat conducting layer may be disposed between the heating element 740 and the corresponding cold plate 510, and two sides of the heat conducting interface layer may be respectively attached to the heating element 740 and the cold plate 510, so that heat of the heating element 740 may be transferred to the cold plate 510 through the heat conducting layer. Wherein the thermally conductive layer may be made of a thermally conductive interface material.

FIG. 3 is a flow chart of liquid cooling of a computing device according to an embodiment of the present application. Referring to fig. 3, the cold plate sets 500 may be multiple sets, and the multiple sets of cold plate sets 500 may be independent from each other. The number of cold plates 510 in each set of cold plates 500 may be one or more, and the number of cold plates 510 in different sets of cold plates 500 may be the same or different.

In addition, the heat exchange group may include a plurality of heat exchangers 200, and the plurality of heat exchangers 200 and the plurality of cold plate groups 500 may be in one-to-one correspondence through the pipe 720, that is, each of the plurality of cold plate groups 500 may be in communication with one heat exchanger 200 through the pipe 720. A circuit for flowing a cooling medium may be formed between the corresponding cold plate group 500 and the corresponding heat exchanger 200. The conduit 720 may be provided with a pump body so that the cooling medium in the circuit may circulate.

It should be noted that the housing 100 may have an air inlet 120 and an air outlet 130. Both the air inlet 120 and the air outlet 130 may be in communication with the interior cavity of the housing 100. The fan 800 may guide air into the inner cavity of the housing 100 through the air inlet 120, and flow out of the air outlet 130 after passing through the heat exchanger 200, so as to achieve air-cooled cooling of the heat exchanger 200. In addition, the fan 800 may also guide air into the inner cavity of the housing 100 through the air inlet 120, and flow out of the air outlet 130 after passing through the heating element 740 or the cold plate 510, so as to achieve air cooling of the heating element 740 or the cold plate 510.

Of course, the heat exchanger 200 and the heating element 740 may also be disposed in different chambers of the housing 100 as shown in fig. 5. Illustratively, in FIG. 5, a laminate 610 may be disposed within the interior cavity of the housing 100. The lamination plate 610 may divide the inner cavity of the case 100 into the heat exchange chamber 110 and the electric chamber 620, that is, the lamination plate 610 and the inner wall surface of the case 100 located at the first side of the lamination plate 610 may form the heat exchange chamber 110, and the lamination plate 610 and the inner wall surface of the case 100 located at the second side of the lamination plate 610 may form the electric chamber 620.

The open arrows in fig. 5 indicate the flow direction of air, and referring to fig. 5, the flow path of air in the heat exchange chamber 110 does not interfere with the flow path of air in the electrical chamber 620 in order to avoid cascade heating effects, i.e., to avoid air flowing through the heat generating element 740 from re-flowing through the heat exchanger 200, or to avoid air flowing through the heat exchanger 200 from re-flowing through the heat generating element 740.

In order to elevate the entire heat exchange area of the device under the heat exchange chamber 110 of a limited size, the sum of the heat exchange areas of the plurality of heat exchangers 200 may be greater than the cross-sectional area of the heat exchange chamber 110.

In addition, the first direction is the air inlet direction of the air, and the first heat exchanger 210 and the second heat exchanger 220 are arranged at intervals along the first direction. The air outlet end of the first heat exchanger 210 is closer to the air inlet of the housing 100 than the air inlet end of the second heat exchanger 220, and a certain distance is provided between the air outlet end of the first heat exchanger 210 and the air inlet end of the second heat exchanger 220 in the first direction.

Wherein, to reduce the flow path of the air, optionally, the air inlet end of the first heat exchanger 210 may be opposite to the air inlet 120. Further, the axis of the air inlet 120 may be parallel or collinear with the normal of the air inlet end of the first heat exchanger 210 as shown in fig. 2, such that the air inlet end of the first heat exchanger 210 is opposite to the air inlet 120, to further reduce the flow path of air.

In addition, in order for air entering the heat exchange chamber 110 through the air intake 120, one portion may pass through the first heat exchanger 210 and another portion may pass through the second heat exchanger 220. The first passage 310 may be formed at the outside of the first heat exchanger 210, the first passage 310 may be connected in parallel with the first heat exchanger 210 downstream of the air intake 120, and air may flow to the second heat exchanger 220 through the first passage 310. Illustratively, the open arrows in fig. 2 indicate the flow direction of air, and referring to fig. 2, air flowing into the heat exchange chamber 110 from the air inlet 120 may partially pass through the first heat exchanger 210 and flow out of the heat exchange chamber 110 through the air outlet 130, and partially may pass through the first channel 310 and through the second heat exchanger 220 and flow out of the heat exchange chamber 110 through the air outlet 130.

The first channel 310 may be formed in the following ways:

referring to fig. 6 and 7, in one possible way of forming the first channel 310, the first channel 310 may be defined by an end surface of the first heat exchanger 210 and a wall surface 119 of the heat exchange cavity 110. As can be appreciated, since the first heat exchanger 210 and the second heat exchanger 220 are spaced apart along the first direction, the first channel 310 cannot be defined by the end surface of the first heat exchanger 210 in the first direction and the wall surface 119 of the heat exchange chamber 110, and the first channel 310 can be defined by at least one of the end surface of the first heat exchanger 210 in the second direction and the end surface of the first heat exchanger 210 in the third direction and the wall surface 119 of the heat exchange chamber 110.

Referring to fig. 7, illustratively, the first heat exchanger 210 abuts the wall 119 of the heat exchange chamber 110 at a first end in the second direction (in the direction of arrow Y), the first heat exchanger 210 having a spacing d1 between the second end in the second direction (in the opposite direction of arrow Y) and the wall 119 of the heat exchange chamber 110 such that the first heat exchanger 210 forms a first channel 310 between the second end in the second direction and the wall 119 of the heat exchange chamber 110; the first heat exchanger 210 is abutted with two wall surfaces 119 of the heat exchange chamber 110 in the third direction at both ends in the third direction (direction of an arrow Z).

Fig. 8 is a schematic diagram of a second arrangement of a first heat exchanger 210 and a second heat exchanger 220 according to an embodiment of the present application. Referring to fig. 8, both ends of the first heat exchanger 210 in the second direction (in the direction of arrow Y) may also have a space with the wall 119 of the heat exchange chamber 110, so that a first channel 310 is formed between both ends of the first heat exchanger 210 in the second direction and the wall 119 of the heat exchange chamber 110.

Fig. 9 is a schematic diagram of a third arrangement of a first heat exchanger 210 and a second heat exchanger 220 according to an embodiment of the present application. Referring to fig. 9, another exemplary embodiment includes the first heat exchanger 210 abutting against the wall 119 of the heat exchange chamber 110 at both ends in the second direction (the direction of arrow Y); the first heat exchanger 210 abuts against the wall 119 of the heat exchange chamber 110 at a first end in the third direction (in the direction indicated by the arrow Z), and the first heat exchanger 210 has a distance d1 between the second end in the third direction (in the direction opposite to the arrow Z) and the wall 119 of the heat exchange chamber 110, so that the second end in the third direction of the first heat exchanger 210 forms a first channel 310 with the wall 119 of the heat exchange chamber 110. Of course, both ends of the first heat exchanger 210 in the third direction may also have a space with the wall 119 of the heat exchange chamber 110, so that both ends of the first heat exchanger 210 in the third direction may form a first channel 310 with the wall 119 of the heat exchange chamber 110.

Fig. 10 is a schematic diagram of a fourth arrangement of a first heat exchanger 210 and a second heat exchanger 220 according to an embodiment of the present application. Referring to fig. 10, still another exemplary embodiment, the first heat exchanger 210 abuts against the wall 119 of the heat exchange chamber 110 at a first end (direction indicated by arrow Y) in the second direction; the first heat exchanger 210 has a distance d1 between the second end in the second direction (the reverse of arrow Y) and the wall 119 of the heat exchange chamber 110 such that the first heat exchanger 210 forms a first channel 310 between the second end in the second direction and the wall 119 of the heat exchange chamber 110. The first heat exchanger 210 has a distance d2 between the first end in the third direction (in the direction indicated by the arrow Z) and the wall 119 of the heat exchange chamber 110, such that the first heat exchanger 210 forms a first channel 310 between the first end in the third direction and the wall 119 of the heat exchange chamber 110; the second end (the direction of arrow Z) of the first heat exchanger 210 in the third direction abuts against the wall surface 119 of the heat exchange chamber 110. Of course, the two ends of the first heat exchanger 210 in the second direction may have a distance from the wall 119 of the heat exchange cavity 110, so that the two ends of the first heat exchanger 210 in the second direction may form a first channel 310 with the wall 119 of the heat exchange cavity 110; the two ends of the first heat exchanger 210 in the third direction may also have a space with the wall 119 of the heat exchange cavity 110, so that the two ends of the first heat exchanger 210 in the third direction may form a first channel 310 with the wall 119 of the heat exchange cavity 110.

Fig. 11 is a schematic diagram of a fifth arrangement of a first heat exchanger 210 and a second heat exchanger 220 according to an embodiment of the present application. Referring to fig. 11, in another possible way of forming the first channel 310, both ends of the first heat exchanger 210 in the second direction (the direction of the arrow Y) are abutted with the wall surface 119 of the heat exchange chamber 110, and both ends of the first heat exchanger 210 in the third direction (the direction of the arrow Z) are abutted with the wall surface 119 of the heat exchange chamber 110. The first heat exchanger 210 may have a through hole in a middle portion thereof, and a first passage 310 may be formed in an inner cavity of the through hole.

Fig. 12 is a schematic diagram of a sixth arrangement of a first heat exchanger 210 and a second heat exchanger 220 according to an embodiment of the present application. Referring to fig. 12, when the number of heat exchangers 200 exceeds two, a plurality of heat exchangers 200 may be spaced apart in the first direction. In the adjacent two heat exchangers 200, a first passage 310 may be formed at the outside of the upstream one, and air may flow to the downstream one of the adjacent two heat exchangers 200 through the first passage 310. That is, one of the adjacent two heat exchangers 200 located upstream may correspond to the first heat exchanger 210 mentioned above, and one located downstream may correspond to the second heat exchanger 220 mentioned above.

In addition, since the number of heat exchangers 200 in the heat exchange chamber 110 is more than two, in order to facilitate the air passing through the last heat exchanger 200 (the heat exchanger 200 near the air outlet 130), the outside of the heat exchanger 200 located before the last heat exchanger 200 may be formed with the first passage. Therefore, when the number of the heat exchangers 200 is more than two, there may be a plurality of first channels 310, and the forming manners of the plurality of first channels 310 may be the same or different, and one of the forming manners of the plurality of first channels 310 may be selected according to circumstances.

Furthermore, the inventors have found that when air passes through two heat exchangers in succession, the heat of the upstream heat exchanger affects the heat of the downstream heat exchanger, i.e. the air passing out of the first heat exchanger 210 is prevented from flowing to the second heat exchanger 220, the cascade heating is prevented from being affected, and referring to fig. 6 to 12, alternatively, the first heat exchanger 210 may be connected with a partition 400, the partition 400 may separate the air outlet end of the first heat exchanger 210 from the air inlet end of the second heat exchanger 220, so that the first heat exchanger 210 and the second heat exchanger 220 are in two mutually independent air ducts, to avoid cascade heating. The separator 400 may be arranged in several possible ways:

For example, when the first passage 310 is formed as shown in fig. 6, 7 and 9, that is, when only one end surface of the first heat exchanger 210 abuts against the wall surface 119 of the heat exchange chamber 110, the separator 400 may have a plate shape. Referring to fig. 6, 7 and 9, a flow guiding space may be limited between the partition 400 and the wall surface 119 of the heat exchange chamber 110, and the flow guiding space may be communicated between the first air outlet portions 131 of the air outlet end of the first heat exchanger 210. The second heat exchanger 220 may be located outside the diversion space and is in communication with the second air outlet 132 of the air outlet. Wherein, in order to increase the heat exchange area, the partition 400 may be optionally connected between the second end of the first heat exchanger 210 in the second direction and the first end of the second heat exchanger 220 in the second direction.

As another example, when the first passage 310 is formed in the manner shown in fig. 8 and 10, that is, when there is a space between at least two end surfaces of the first heat exchanger 210 and the wall surface 119 of the heat exchange chamber 110, the separator 400 may be tubular in shape. Referring to fig. 8 and 10, the inner cavity of the partition 400 may be communicated between the air outlet end of the first heat exchanger 210 and the first air outlet portion 131 of the air outlet. In fig. 8 and 10, the air outlet end of the first heat exchanger 210 is the end of the first heat exchanger 210 indicated by the arrow X, and the first air outlet portion 131 of the air outlet is disposed at the end of the heat exchange cavity 110 indicated by the arrow Y. The axis of the first air outlet 131 of the air outlet may be perpendicular to a plane formed by the first direction and the third direction, i.e. an XZ plane.

That is, the partition 400 may have a first open end and a second open end, the first open end of the partition 400 may communicate with the air outlet end of the first heat exchanger 210, and the second open end of the partition 400 may communicate with the air outlet 130. The second heat exchanger 220 is located at the outer side of the partition 400 and communicates with the second air outlet portion 132 of the air outlet. In fig. 8 and 10, a first open end of the separator 400 is disposed at an end of the separator 400 opposite to the arrow X, and a second open end of the separator 400 is disposed at an end of the separator 400 indicated by the arrow Y.

Still another example, when the first passage 310 is formed as shown in fig. 11, that is, when a through hole is provided in the middle of the first heat exchanger 210, the separator 400 may have a tubular shape. Referring to fig. 11, the inner cavity of the partition 400 may be communicated between the through-hole and the air inlet end of the second heat exchanger 220.

Still further exemplary, referring to fig. 12, when the number of the heat exchangers 200 exceeds two, the number of the separators 400 may be plural, and the arrangement manner of the plurality of separators 400 may be the same or different, and each of the arrangement manners of the separators 400 may be one of the above-mentioned arrangement manners of the plurality of separators 400 according to circumstances.

Referring to fig. 6 to 12, the second heat exchanger 220 may be spaced apart from the first heat exchanger 210 in a first direction (a direction in which an arrow X is located). The second heat exchanger 220 may have an air inlet end and an air outlet end in the first direction, and air may pass through the air inlet end of the second heat exchanger 220 via the first channel 310 to enter the second heat exchanger 220, exchange heat with the cooling medium in the pipeline of the second heat exchanger 220, and flow out of the second heat exchanger 220 via the air outlet end of the second heat exchanger 220. To reduce the flow path of the air, the air intake end of the second heat exchanger 220 may be opposite the first passage 310. Further, referring to fig. 6-12, the axis of the first channel 310 may be parallel or collinear with a normal to the air intake end of the second heat exchanger 220 such that the air intake end of the second heat exchanger 220 is directly opposite the first channel 310.

Alternatively, in order to increase the heat exchange efficiency of the apparatus, the size of the air inlet end of the second heat exchanger 220 may be larger than the size of the first flow channel. In order to maximize the inlet air area of the second heat exchanger while also being able to direct air exiting the first channel 310 to the second heat exchanger 220, at least a portion of the partition 400 may be inclined with respect to the first direction (the direction of arrow X), with reference to fig. 6-12.

Illustratively, in fig. 6 and 7, at least a portion of the partition 400 is connected between the second end of the first heat exchanger 210 in the second direction (the reverse of arrow Y) and the first end of the second heat exchanger 220 in the second direction (the direction of arrow Y). In fig. 5, at least a part of the partition 400 is connected between the second end of the first heat exchanger 210 in the third direction (the direction of arrow Z) and the first end of the second heat exchanger 220 in the second direction (the direction of arrow Z). In fig. 8 and 10, the partition 400 may have a triangular cross section, and the tip of the triangle may be disposed toward the second heat exchanger 220.

Optionally, as shown in fig. 8 and 10, the outer edge of the second heat exchanger 220 may abut against the wall 119 of the heat exchange cavity 110, so as to increase the heat exchange area of the second heat exchanger 220, thereby increasing the efficiency of the second heat exchanger 220. Alternatively, referring to fig. 6, 7, 9 and 11, a second channel 320 may be formed between the outer edge of the second heat exchanger 220 and the wall 119 of the heat exchange cavity 110, and the air outlet end of the first heat exchanger 210, the second channel 320 and the air outlet 130 may be opposite, so that air passing through the first heat exchanger 210 may flow out of the air outlet 130 through the second channel 320, so as to reduce a flow path of the air in the heat exchange cavity 110.

For example, in fig. 6 and 7, the second heat exchanger 220 has a distance d2 between one end (the direction indicated by the arrow Y) in the second direction and the wall 119 of the heat exchange cavity 110, so that a second channel 320 is formed between one end of the second heat exchanger 220 in the second direction and the wall 119 of the heat exchange cavity 110; the second heat exchanger 220 is in contact with the wall 119 of the heat exchange chamber 110 at a second end (the reverse direction of arrow Y) in the second direction; the second heat exchanger 220 abuts against the wall surface 119 of the heat exchange chamber 110 at both ends in the third direction (the direction of the arrow Z). The hollow arrows in fig. 6 indicate the flow direction of the air, and referring to fig. 6, a portion of the air may sequentially pass through the air inlet 120, the first heat exchanger 210, and the first air outlet portion 131 of the air outlet in the first direction (the direction of the arrow X), and another portion of the air may sequentially pass through the air inlet 120, the second heat exchanger 220, and the second air outlet portion 132 of the air outlet in the first direction, so as to reduce the path of the air in the heat exchange cavity 110.

In fig. 9, both ends of the second heat exchanger 220 in the second direction (the direction of the arrow Y) are respectively abutted against the wall surface 119 of the heat exchange chamber 110; the second heat exchanger 220 has a distance d2 between the first end in the third direction (direction indicated by arrow Z) and the wall 119 of the heat exchange chamber 110 such that the second end of the second heat exchanger 220 in the third direction forms a second channel 320 with the wall 119 of the heat exchange chamber 110. The second heat exchanger 220 abuts against the wall 119 of the heat exchange chamber 110 at a second end (the direction of arrow Z) in the third direction. Of course, the second heat exchanger 220 may also have a space between both ends in the third direction and the wall 119 of the heat exchange chamber 110, such that the second heat exchanger 220 may form a second channel 320 between both ends in the third direction and the wall 119 of the heat exchange chamber 110.

In fig. 11, the second heat exchanger 220 has a space between both ends in the second direction (the direction of the arrow Y) and the wall 119 of the heat exchange chamber 110, so that a second passage 320 is formed between both ends of the second heat exchanger 220 in the second direction and the wall 119 of the heat exchange chamber 110.

The above is described by way of example of the arrangement of the plurality of heat exchangers 200 shown in fig. 6 to 12, that is, the plurality of heat exchangers 200 are arranged at intervals in the first direction (the direction in which the arrow X is located) and the first direction is arranged along the intake direction of the air. In addition to the arrangement of the plurality of heat exchangers 200 in fig. 6 to 12, there may be an arrangement of the plurality of heat exchangers 200 as shown in fig. 13 to 17.

Referring to fig. 13-17, the plurality of heat exchangers 200 may include a third heat exchanger 230 and a fourth heat exchanger 240, the third heat exchanger 230 and the fourth heat exchanger 240 being spaced apart in the second direction, and a sum of heat exchanging areas of the third heat exchanger 230 and the fourth heat exchanger 240 being greater than a cross-sectional area of a heat exchanging cavity of the case. In order to increase the heat exchange area, the included angle between the third heat exchanger 230 and the air inlet direction and the included angle between the third heat exchanger 240 and the air inlet direction may be greater than 0 degrees and less than 90 degrees, that is, the extending direction of the air inlet end of the third heat exchanger 230 and the extending direction of the fourth heat exchanger 240 intersect with the air inlet direction, and the intersecting angle is not equal to 90 degrees. Fig. 13 to 17 illustrate that the air intake direction is the direction indicated by the arrow X, the angle between the third heat exchanger 230 and the direction indicated by the arrow X is α, and the angle between the fourth heat exchanger 240 and the direction indicated by the arrow X is β.

In order to avoid the influence of the cascade heating, referring to fig. 13, a partition 400 may be disposed in the heat exchange cavity 110, and the partition 400 may partition the heat exchange cavity 110 into at least two mutually independent air channels, each of which may be connected between the air inlet 120 and the air outlet 130, that is, a plurality of air channels may be connected in parallel between the air inlet 120 and the air outlet 130. The third heat exchanger 230 and the fourth heat exchanger 240 may be distributed in different air channels.

Illustratively, fig. 13 illustrates the heat exchange chamber 110 divided into a first air duct 111 and a second air duct 112 independent of each other by a partition 400, a third heat exchanger 230 is disposed in the first air duct 111, and a fourth heat exchanger 240 is disposed in the second air duct 112. The hollow arrow in fig. 13 indicates the flow direction of the air, referring to fig. 13, the air entering the heat exchange chamber 110 through the air inlet 120 may be divided into two parts by the partition 400, one part of the air may enter the first air duct 111 and may flow out of the third air outlet portion 133 of the air outlet 130 after exchanging heat with the third heat exchanger 230, the other part of the air may enter the second air duct 112 and may flow out of the fourth air outlet portion 134 of the air outlet 130 after exchanging heat with the fourth heat exchanger 240, wherein the third air outlet portion 133 and the fourth part 134 may be independent from each other.

It should be noted that, when the above-mentioned partition 400 is disposed in the heat exchange cavity 110 so that the third heat exchanger 230 and the fourth heat exchanger 240 are distributed in different air channels, the arrangement manner of the third heat exchanger 230 and the fourth heat exchanger 240 is not limited in the embodiment of the present application. Illustratively, at this time, the extension line of the air inlet end of the third heat exchanger 230 and the extension line of the air inlet end of the fourth heat exchanger 240 may intersect; alternatively, the third heat exchanger 230 and the fourth heat exchanger 240 may be arranged in parallel as shown in fig. 13. In addition, when the above-mentioned partition 400 is disposed in the heat exchange cavity 110 so that the third heat exchanger 230 and the fourth heat exchanger 240 are distributed in different air channels, the inclination directions of the third heat exchanger 230 and the fourth heat exchanger 240 are not specifically limited in the embodiment of the present application. For example, at this time, the end of the third heat exchanger 230 close to the air inlet 120 may be higher than the end of the third heat exchanger 230 far from the air inlet 120 as shown in fig. 13; alternatively, the end of the third heat exchanger 240 near the air inlet 120 may be lower than the end of the third heat exchanger 230 far from the air inlet 120.

In addition, in addition to the above-mentioned partition 400 being provided in the heat exchange chamber 110 so that the third heat exchanger 230 and the fourth heat exchanger 240 are distributed in different air channels, the cascade heating effect can be eliminated as follows.

The open arrows in fig. 14 indicate the air flow direction, and referring to fig. 14, in another possible implementation manner of eliminating the cascade heating effect, the air inlet end of the third heat exchanger 230 and the air inlet end of the fourth heat exchanger 240 may be disposed opposite to each other, and an air inlet space 113 communicating with the air inlet 120 may be formed between the air inlet end of the third heat exchanger 230 and the air inlet end of the fourth heat exchanger 240. That is, the air flowing into the heat exchange cavity 110 through the air inlet 120 may all enter the air inlet space 113, a part of the air in the air inlet space 113 may pass through the third heat exchanger 230 and may exchange heat with the third heat exchanger 230, and another part of the air in the air inlet space 113 may pass through the fourth heat exchanger 240 and may exchange heat with the fourth heat exchanger 230; in other words, the air intake space 113 is located upstream of the third heat exchanger 230 and the fourth heat exchanger 240, and the third heat exchanger 230 and the fourth heat exchanger 240 are connected in parallel downstream of the air intake space 113.

With continued reference to fig. 14, the air outlet end of the third heat exchanger 230 and the air outlet end of the fourth heat exchanger 240 may be disposed opposite to each other. The first air outlet space 114 may be formed outside the air outlet end of the third heat exchanger 230, and the first air outlet space 114 may be communicated between the air outlet end of the third heat exchanger 230 and at least a portion of the air outlet 130 (the first air outlet portion 133). The second air outlet space 115 is formed outside the air outlet end of the fourth heat exchanger 240, and the second air outlet space 115 may be communicated between the air outlet end of the fourth heat exchanger 240 and at least a portion of the air outlet 130 (the second air outlet 134). That is, the air flowing out of the third heat exchanger 230 may directly flow out of the air outlet 130 (the first air outlet 133) through the first air outlet space 114, so as to avoid the air flowing out of the third heat exchanger 230 from blowing to the fourth heat exchanger 240, and further avoid cascade heating. The air flowing out of the fourth heat exchanger 240 may directly flow out of the air outlet 130 (the second air outlet 134) through the second air outlet space 115, so as to avoid the air flowing out of the fourth heat exchanger 240 from blowing to the third heat exchanger 230, so as to avoid cascade heating.

The first air outlet space 114 may be formed in the following ways:

the method comprises the following steps: referring to fig. 14, the air outlet 130 may include a third air outlet portion 133 and a fourth air outlet portion 134 that are independent from each other. The third heat exchanger 230 may have a first end and a second end opposite to each other in the extending direction thereof, and the first end of the third heat exchanger 230 is closer to the air inlet 120 than the second end thereof. The first end of the third heat exchanger 230 may abut against the wall 119 of the heat exchange chamber 110, and the second end of the third heat exchanger 230 may have a certain distance from the wall 119 of the heat exchange chamber 110. The heat exchange cavity 110 may be provided with a partition 400, the partition 400 may be plate-shaped, the partition 400 may be disposed between the second end of the third heat exchanger 230 and the wall surface 119 of the heat exchange cavity 110 provided with the third air outlet 133, and the partition 400 may form the first air outlet space 114 with the wall surface 119 of the heat exchange cavity 110 located at the air outlet side of the third heat exchanger 230. The first air outlet space 114 may be connected between an air outlet end of the third heat exchanger 230 and the third air outlet 133.

And two,: referring to fig. 15, the first end of the third heat exchanger 230 and the second end of the third heat exchanger 230 may have a certain distance from the wall 119 of the heat exchange chamber 110. The partition 400 may have a tubular shape, and the first air outlet space 114 may be formed inside the partition 400. The first air outlet space 114 may be connected between an air outlet end of the third heat exchanger 230 and the third air outlet 133.

And thirdly,: referring to fig. 16, when the first end of the third heat exchanger 230 and the second end of the third heat exchanger 230 may both abut against the wall surface 119 of the heat exchange cavity 110, the wall surface 119 of the heat exchange cavity 110 located at the air outlet end side of the third heat exchanger 230 may be formed with a first air outlet space 114, and the first air outlet space 114 may be communicated between the air outlet end of the third heat exchanger 230 and the third air outlet portion 133.

Similarly, the formation of the second air-out space 115 can be simply replaced by referring to the formation of the first air-out space 114, which is described above, and will not be repeated here.

It should be noted that, as shown in fig. 14, the third air outlet portion 133 and the fourth air outlet portion 134 of the air outlet 130 may be disposed at intervals on the same wall 119 of the heat exchange cavity 110; alternatively, the third air outlet portion 133 and the fourth air outlet portion 134 of the air outlet 130 may be disposed on two opposite wall surfaces 119 of the heat exchange cavity 110 as shown in fig. 16; alternatively, the third air outlet portion 133 and the fourth air outlet portion 134 of the air outlet 130 may be disposed on two adjacent or intersecting wall surfaces 119 of the heat exchange cavity 110 as shown in fig. 15.
