Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

Referring to fig. 1, in an embodiment of the present application, an air-cooled cabinet 10 is provided, where the air-cooled cabinet 10 is configured to be installed in a designated area, and is operable to provide air conditioning to the designated area, and optionally, the air conditioning includes, but is not limited to, cooling, dehumidifying, heating, and the like. It should be noted that, the air cooling cabinet 10 provided in this embodiment can improve the technical problem that the air outlet effect is affected due to the uneven air field in the air duct of the air cooling cabinet in the prior art.

In this embodiment, referring to fig. 1 and 2 in combination, an air-cooled cabinet 10 includes a housing 100, a heat exchanger 200, and an air guide assembly 300. An air guide channel 101 is arranged in the shell 100; the casing 100 has a front panel 110 and a back panel 120, and the front panel 110 is provided with an air outlet 111 for the air guide channel 101 to air out; an air inlet 130 is provided at the bottom of the housing 100 to allow air to enter the air guide channel 101. The heat exchanger 200 is disposed in the air guide channel 101 and is disposed between the front panel 110 and the back panel 120 in an inclined manner, so that the air inlet 130 and the air outlet 111 are respectively located at two opposite sides of the heat exchanger 200. The air guide assembly 300 comprises at least one air guide block 301, wherein the air guide block 301 is arranged on the back plate 120; the air guide block 301 is provided with an air guide surface 310 biased toward the heat exchanger 200 on a side facing the air inlet 130, and is used for guiding the air flow guided from the air inlet 130 to flow biased toward the heat exchanger 200.

In the above-mentioned manner, during the operation of the air-cooled cabinet 10, the air flow is led into the air-guiding channel 101 from the air inlet 130, the led air flow flows upward along the back plate 120, and part of the air flow is guided by the air-guiding surface 310 to flow toward the heat exchanger 200 under the condition of flowing to the air-guiding surface 310, so that the air field led into the air-guiding channel 101 can be changed by the arrangement of the air-guiding block 301, the air field led into the air-guiding channel 101 is changed, the air flow is caused to be blown onto the heat exchanger 200 uniformly, and the air-out effect of the air-cooled cabinet 10 is improved. Based on this, the air cooling cabinet 10 provided by the utility model can solve the technical problem that the air outlet effect is affected due to the uneven wind field in the prior art.

It should be understood that the air cooling cabinet 10 provided in this embodiment may further include other parts such as a compressor, a fan, and an expansion valve, so that the functions of the air cooling cabinet 10 are implemented, and the other parts are all in the prior art and are not described herein.

Generally, in the running process of the air-cooled cabinet 10, because a certain angle exists between the air inlet direction and the air outlet direction, under the condition that the air guide assembly 300 is not arranged, the air flow led in from the air inlet 130 flows from bottom to top, and forms impact scattering after reaching the top of the shell 100, so that the air flow in the air guide channel 101 is disordered, and the air outlet effect is affected; moreover, the top of the air guide channel 101 is a concentration area of air flow, so that the heat exchange effect of each position of the heat exchanger 200 is different, and the air outlet effect of the air-cooled cabinet 10 is affected.

Based on this, the air-cooled cabinet 10 provided in this embodiment may set the air guiding assembly 300 on the back plate 120, and provide a guiding effect for a part of the airflow through the air guiding block 301, so that the part of the airflow is guided to flow toward the heat exchanger 200 under the condition that the part of the airflow does not reach the top of the casing 100, which not only can prevent the airflow from concentrating on the top of the air guiding channel 101, but also is beneficial to forming a uniform wind field in the air guiding channel 101, and is beneficial to uniformly blowing the airflow toward the heat exchanger 200, thereby being beneficial to improving the heat exchange effect of the heat exchanger 200 and the airflow, and further achieving the purpose of improving the air outlet effect.

It should be noted that, in the case of fig. 1 as an example, the air intake direction is an upward direction, that is, a vertical direction, as indicated by an arrow B in fig. 1; the direction of the air outlet is the left direction, namely the transverse left direction, as indicated by an arrow A in FIG. 1. After the air guide block 301 is arranged on the back plate 120, the air guide surface 310 formed on the air guide block 301 is inclined leftwards, so that the air flow guided by the air inlet 130 in the vertical direction can be guided leftwards, the air flow guided by the air guide surface 310 can flow leftwards conveniently, the longitudinal distribution of the air field in the air guide channel 101 is facilitated to be uniform, and the air outlet effect of the air cooler 10 is improved.

In this embodiment, the air guiding block 301 is disposed on the back plate 120 in a protruding manner, and the thickness of the side of the air guiding block 301 close to the air inlet 130 is gradually increased from bottom to top, so as to form an air guiding surface 310 on the side of the air guiding block 301 away from the back plate 120. The air guide block 301 is arranged to be of a convex block structure, so that the overall strength of the air guide block 301 can be improved, the air guide block 301 is prevented from being damaged by collision of other parts, the stability of the air guide block 301 is further ensured, and the service life of the air guide block 301 is prolonged.

It should be understood that, in other embodiments of the present application, the air guiding block 301 may take other forms. For example, the air guide block 301 is provided in a plate-like structure provided obliquely on the back plate 120; the plate-like structure forms an inclined wind guiding surface 310 at a side facing the wind inlet 130, and the purpose of affecting the wind field can be achieved as well. For another example, the air guiding block 301 may be directly punched from the back plate 120, where a recess corresponding to the air guiding block 301 is formed on a side of the back plate 120 facing away from the air guiding channel 101; in this case, the air guide block 301 may be regarded as a hollow structure.

Optionally, the air guiding surface 310 is planar. The air guiding surfaces 310 are arranged to be planar, so that the acting directions of the air flows born by the positions of the air guiding surfaces 310 are the same, and the directions of the air flows formed after the air flows impact the air guiding surfaces 310 are the same, which is beneficial to guiding the air flows by the air guiding surfaces 310, reducing the turbulence of the air flows at the air guiding surfaces 310 and improving the air outlet effect.

Specifically, the air guiding block 301 has a certain height relative to the back plate 120, and in the area covered by the height of the air guiding block 301, the air flow introduced from the air inlet 130 directly acts on the air guiding surface 310; since the flowing directions of the airflows introduced from the air inlet 130 are approximately the same, the flowing directions of the airflows acting on each position on the air guiding surface 310 are approximately the same, so that the directions of the airflows formed by the airflows on each position on the air guiding surface 310 after impacting the air guiding surface 310 are approximately the same, which is beneficial to orderly flowing of the airflows, further beneficial to uniform flowing of the airflows, so as to form a uniform wind field, and beneficial to improving the air outlet effect of the air-cooled cabinet 10.

Of course, in other embodiments of the present application, the air guiding surface 310 may also be formed in other shapes. For example, an arc; for another example, the air guide surface 310 may be formed into a multi-surface structure having a plurality of flat surfaces. It should be noted that, in the case that the wind guiding surface 310 forms an arc shape or a multi-surface shape, it can guide the vertical airflow to form the airflow deflected to the horizontal direction, so as to achieve the purpose of improving the wind field.

Further, the cross section of the wind guiding block 301 is triangular, trapezoidal, parallelogram or fan-shaped. That is, the shape of the leeward side of the air guiding block 301 may be variously set, and the overall shape of the air guiding block 301 may be designed based on the strength, the setting space, the air flow guiding of the leeward side, and other factors, so that the air guiding block 301 provides a suitable positive influence on the air flow in the air guiding channel 101, and the overall air outlet effect of the air cooler 10 is improved.

Generally, in order to facilitate the manufacture and processing of the air guide block 301, the cross section of the air guide block 301 is configured to be triangular or trapezoidal.

In addition, when the cross section of the air guide block 301 is fan-shaped, the air guide block 301 forms an arc-shaped curved surface on the leeward side. The part of the airflow passing over the air guide blocks 301 in the air guide channel 101 can flow along the arc-shaped curved surface on the leeward side of the air guide blocks 301 based on the wall attaching effect, so that the windless area on the leeward side of the air guide blocks 301 can be reduced, and under the condition that the number of the air guide blocks 301 is multiple, the air guide surface 310 at the position of the other air guide blocks 301 is favorable to have enough airflow, and therefore the uniformity of wind fields is favorable.

In the present embodiment, referring to fig. 1 and 3, the extending direction of the air guiding block 301 is perpendicular to the air inlet direction. After the air flow is led in from the air inlet 130, the distances between each position of the air guide block 301 and the air inlet 130 are the same, on one hand, it can be ensured that after the air flow is led in the air guide channel 101, the air guide block 301 provides a uniform influence on the air flow, so that a uniform wind field is formed in the air guide channel 101, and the air outlet effect of the air cooler 10 is improved. On the other hand, the difficulty in installing and manufacturing the air guide block 301 can be reduced, and the manufacturing cost of the air cooler 10 can be reduced. The direction indicated by the arrow C in fig. 3 is the extending direction of the air guiding block 301.

Of course, in other embodiments, the specific arrangement manner of the air guiding block 301 may be adjusted according to the actual situation. For example, the extending path of the air guide block 301 may be provided in a V-shape, a W-shape, a curved shape, or the like.

Further, in the extending direction of the air guide block 301, the length of the air guide block 301 is equal to the width of the heat exchanger 200. The air flow can be effectively guided to the heat exchanger 200 through the air guide blocks 301 with the same width as the heat exchanger 200, so that the wind fields of all areas of the heat exchanger 200 can be regulated by the air guide blocks 301, the uniformity of the wind fields of the areas corresponding to the heat exchanger 200 in the air guide channel 101 is facilitated, and the air outlet effect of the air-cooled cabinet 10 is facilitated to be improved.

If the length of the air guide block 301 is smaller than the width of the heat exchanger 200, the corresponding positions of part of the heat exchangers 200 cannot form air flow guidance, and therefore a uniform air field cannot be formed, the air flow in the air guide channel 101 is affected, and the air outlet effect of the air cooling cabinet 10 is affected; if the length of the air guide block 301 is greater than the length of the heat exchanger 200, it is not significant that the air guide block 301 beyond the area defined by the width of the heat exchanger 200 cannot directly pass through the heat exchanger 200 even if the flow direction of the air flow is adjusted. Based on this, the length of the air guide block 301 is set to be adapted to the width of the heat exchanger 200, which is advantageous for improving the air outlet effect, and does not generate additional cost increase.

In addition, in this embodiment, the air guiding block 301 may be assembled to the back plate 120 in a detachable connection manner, based on this, a plurality of assembling holes may be formed on the back plate 120 to facilitate adjusting the position of the air guiding block 301, and thus, the air outlet of the air cooler 10 may be adjusted according to the actual situation, so as to adjust the air outlet effect of the air cooler 10 to be optimal. Of course, in other embodiments of the present application, the air guiding block 301 may be disposed on the back plate in other manners, for example, a snap-fit manner; also for example, the manner of bonding; also, for example, the air guide block 301 is integrally formed with the back plate 120. The air guide block 301 and the back plate 120 may be integrally formed by direct injection molding, or may be formed by punching the back plate 120 to form the air guide block 301.

In this embodiment, the air guiding assembly 300 includes a plurality of air guiding blocks 301, and the plurality of air guiding blocks 301 are disposed on the back plate 120 at intervals along the air inlet direction. The air field in the air guide channel 101 is adjusted through the plurality of air guide blocks 301 at different positions, so that the air receiving effect of the plurality of areas on the heat exchanger 200 can be guaranteed to be adjusted by the air guide blocks 301, the air receiving uniformity of the heat exchanger 200 is facilitated, and the air outlet effect of the air cooler 10 is improved.

Because the wind guiding block 301 can convert the vertical airflow into the airflow deflected transversely, based on this, the wind guiding block 301 is arranged at a plurality of positions on the back plate 120, and the airflow deflected transversely can be formed at a plurality of positions, so that the vertical airflow is converted into the airflow deflected transversely at a plurality of positions, the uniform wind field is formed in the wind guiding channel 101, and the wind outlet effect of the wind-cooling cabinet 10 is improved.

Of course, in other embodiments of the present application, an air guiding block 301 may also be disposed on the back plate 120.

In addition, the distance between any two adjacent air guide blocks 301 is larger than the width of the air guide blocks 301 in the air inlet direction.

In the air intake direction, under the condition that the air guide block 301 at the front side is subjected to air, an airless area with a certain width is formed on the leeward side of the air guide block 301, so that the distance between the air guide block 301 at the rear side and the air guide block 301 at the front side is set to be larger than the width of the air guide block 301, the airless area on the leeward side of the air guide block 301 can be avoided as much as possible, further, the effective air guide effect can be provided by a plurality of air guide blocks 301, the uniform air field can be formed in the air guide channel 101, and the air outlet effect of the air cooler 10 can be improved.

In this embodiment, the protrusions of the plurality of air guiding blocks 301 are the same height with respect to the back plate 120. The plurality of air guide blocks 301 are identical in height relative to the back plate 120, so that the same air guide effect provided by the plurality of air guide blocks 301 is guaranteed, the air field balance of each area in the air guide channel 101 is facilitated, the uniformity of the air field is facilitated, and the air outlet effect is improved.

It should be noted that, after the air flow is introduced from the air inlet 130, part of the air flow directly impinges on the air guiding block 301, and is converted into the air flow biased to the lateral direction by the air guiding block 301, and the other part of the air flow passes over the air guiding block 301 to continue to flow upwards; during the continued flow of the airflow, the air pressure causes the area between two adjacent wind guiding blocks 301 to form following airflow, and thus the windless area on the leeward side of the previous wind guiding block 301 can be reduced. Therefore, even if the heights of the plurality of air guide blocks 301 are uniform, there is sufficient airflow acting on the air guide blocks 301 located rearward in the air intake direction.

It should be appreciated that in other embodiments of the present application, the height of the protrusions of the plurality of air guiding blocks 301 with respect to the back plate 120 may also be different, for example, the height of the air guiding block 301 located at the front side is lower, and the height of the air guiding block 301 located at the rear side is higher than the height of the previous air guiding block 301.

In addition, in the present embodiment, the top of the heat exchanger 200 is in contact with the back plate 120; the distance between the top air guide block 301 and the top of the heat exchanger 200 is smaller than the distance between two adjacent air guide blocks 301. Because the distance between the top of the heat exchanger 200 and the back plate 120 is relatively close, the area between the top of the heat exchanger 200 and the back plate 120 is relatively narrow, the distance between the air guide block 301 and the top of the heat exchanger 200 is shortened, an effective guiding effect is provided at the position with relatively small wind power at the tail end of the air guide channel 101, the air receiving uniformity of the top of the heat exchanger 200 and other positions is facilitated, and the air outlet effect is improved.

Further, in the present embodiment, the extending directions of the plurality of air guide blocks 301 are parallel to each other. On one hand, the same air guiding effect provided by the plurality of air guiding blocks 301 can be ensured, and the air outlet effect of each area of the air guiding channel 101 is quite convenient; on the other hand, the manufacturing difficulty of the plurality of air guide blocks 301 can be reduced, and the manufacturing cost is reduced.

In summary, during the operation of the refrigerator 10, the air flow is led into the air guiding channel 101 from the air inlet 130, the led air flow flows upward along the back plate 120, and part of the air flow is guided by the air guiding surface 310 to flow toward the heat exchanger 200 under the condition of flowing to the air guiding surface 310, so that the air field led into the air guiding channel 101 can be changed by the arrangement of the air guiding block 301, so that the air field led into the air guiding channel 101 is changed, the air flow is caused to be blown onto the heat exchanger 200 uniformly, and the air outlet effect of the refrigerator 10 is improved. Based on this, the air cooling cabinet 10 provided by the utility model can solve the technical problem that the air outlet effect is affected due to the uneven wind field in the prior art. The air guide surface 310 is set to be a plane, so that the acting directions of the air flows born by all positions of the air guide surface 310 are the same, and the directions of the air flows formed after the air flows impact the air guide surface 310 are the same, which is beneficial to guiding the air flows by the air guide surface 310, reducing the turbulence of the air flows at the air guide surface 310 and improving the air outlet effect. In addition, the air field in the air guide channel 101 is adjusted through the plurality of air guide blocks 301 at different positions, so that the air receiving of a plurality of areas on the heat exchanger 200 can be adjusted by the air guide blocks 301, the air receiving of the heat exchanger 200 is uniform, and the air outlet effect of the air cooler 10 is improved. In addition, in the air intake direction, under the condition that the air guide block 301 positioned at the front side receives air, an airless area with a certain width is formed on the leeward side of the air guide block 301, therefore, the distance between the air guide block 301 positioned at the rear side and the air guide block 301 positioned at the front side is set to be larger than the width of the air guide block 301, the airless area on the leeward side of the air guide block 301 can be avoided as much as possible, further, the effective air guide effect can be provided by a plurality of air guide blocks 301, the uniform air field can be formed in the air guide channel 101, and the air outlet effect of the air cooler 10 can be improved.
