Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a cabinet. Background Art

[0002] 5G minimalist sites usually have cabinets, which are used to distribute power to 5G equipment. With the large-scale deployment of 5G minimalist sites and the improvement of communication performance, the power distribution demand of 5G equipment has increased significantly. The future power distribution demand in the market will reach 12,000W, and the corresponding equipment heat consumption will reach 800W. The power distribution capacity of existing cabinets is 8,000W, and the corresponding equipment heat consumption is 400W. Therefore, the existing cabinets will not be able to meet the demand. Existing cabinets usually use heat exchangers to dissipate heat. The internal equipment fan drives the internal circulation airflow to form an internal flat U-shaped air duct, which exchanges heat with the external circulation airflow through the heat exchange core. However, the flat U-shaped air duct has a low space utilization rate inside the cabinet, and the airflow effect is not good, resulting in poor heat dissipation capacity of the cabinet. Summary of the invention

[0003] The present application provides a cabinet which can improve the space utilization rate in the cabinet by optimizing the circulating air duct in the cabinet, thereby improving the efficiency of the internal circulating airflow and solving the problem of poor heat dissipation capacity of the cabinet in the prior art.

[0004] An embodiment of the present application provides a cabinet, the cabinet comprising:

[0005] shell;

[0006] A heat generating device, the heat generating device is located in the housing and has a device cavity;

[0007] a heat exchanger, the heat exchanger being located in the housing and having a heat exchanger cavity;

[0008] Wherein, the heat generating device and the heat exchanger are distributed along a first direction;

[0009] Along the second direction, an air inlet cavity and an air outlet cavity are respectively provided between the two ends of the heat generating device and the housing;

[0010] Along the third direction, a first cavity and a second cavity are respectively provided between the two ends of the heat generating device and the shell, and a third cavity and a fourth cavity are respectively provided between the two ends of the heat exchanger and the shell;

[0011] After the airflow enters the air inlet cavity, it can flow through the equipment cavity, the air outlet cavity, the first cavity, the third cavity, the heat exchanger cavity, the fourth cavity, and enter the air inlet cavity from the fourth cavity;

[0012] The heat exchanger is used for heat exchange between the external airflow and the airflow entering the heat exchanger cavity through the third cavity.

[0013] In the above scheme, the cabinet makes full use of the space inside the cabinet to set the air inlet cavity, the air outlet cavity, the first cavity, the second cavity, the third cavity and the fourth cavity, optimizes the internal circulation air duct, expands the flow range of the airflow in the cabinet, and improves the space utilization inside the cabinet, so that the airflow flows through each cavity space in turn, and because the airflow can move along the first direction and the third direction during one circulation process, a three-dimensional internal circulation air duct is formed, which can dissipate heat in multiple directions inside the cabinet, thereby improving the heat dissipation capacity of the cabinet.

[0014] In a possible design, the first cavity and the third cavity are connected to form a first through cavity, and the second cavity and the fourth cavity are connected to form a second through cavity.

[0015] In the above scheme, the first cavity is connected with the third cavity, which reduces the resistance of the airflow when it flows from the first cavity into the third cavity. At the same time, the space of the first through cavity formed by the connection is larger than the space of the first cavity and the third cavity, so that the airflow accommodation space and flow space are increased, thereby increasing the amount of air entering the heat exchanger cavity for heat exchange with the external airflow; similarly, the space of the second through cavity formed by the connection of the second cavity and the fourth cavity is larger than the space of the second cavity and the fourth cavity, so that the airflow accommodation space and flow space are increased, thereby increasing the amount of air entering the fourth cavity into the air inlet cavity to continue the next cycle, thereby improving the utilization rate of the airflow in the first cavity and the fourth cavity.

[0016] In a possible design, the first cavity is connected to the third cavity through the air outlet cavity, and the second cavity is connected to the fourth cavity.

[0017] In the above scheme, the air outlet cavity is connected with the first cavity and the third cavity respectively, and a part of the airflow in the air outlet cavity flows directly from the air outlet cavity into the third cavity, and the other part flows into the first cavity along the second direction and then flows into the third cavity along the first direction. At this time, the resistance of the airflow flowing into the third cavity is less than the resistance entering the third cavity along a single path, thereby promoting the airflow to flow from the air outlet cavity into the third cavity; similarly, the second cavity is connected with the fourth cavity, and a part of the airflow in the fourth cavity can flow into the second cavity along the first direction, so that the airflow in the fourth cavity is reduced, thereby reducing the resistance of the airflow when flowing from the fourth cavity into the air inlet cavity, thereby promoting the airflow to flow from the fourth cavity into the air inlet cavity.

[0018] In a possible design, the airflow in the heat exchanger cavity can enter the fourth cavity and the second cavity, and enter the air inlet cavity from the second cavity.

[0019] In the above scheme, a part of the airflow in the fourth cavity flows into the second cavity along the first direction and then flows into the air inlet cavity along the second direction, and another part of the airflow flows directly into the air inlet cavity from the fourth cavity. At this time, the resistance of the airflow flowing into the air inlet cavity is less than the resistance of flowing into the air inlet cavity along a single path, thereby allowing more airflow to flow into the air inlet cavity from the fourth cavity.

[0020] In a possible design, the cabinet further includes a partition located between the heat-generating device and the heat exchanger.

[0021] In the above scheme, the partition is used to separate the heat-generating equipment and the heat exchanger. At the same time, each end face of the partition is respectively connected to the outer shell, thereby forming a mutually independent air inlet cavity, air outlet cavity, first cavity, second cavity, third cavity and fourth cavity inside the cabinet, making full use of the space inside the cabinet, so that the airflow passes through each cavity space in the cabinet in turn and circulates, thereby improving the utilization rate of the internal space of the cabinet.

[0022] In a possible design, the partition is provided with a connecting port, and the connecting port connects the fourth cavity and the air inlet cavity.

[0023] During the operation of the cabinet, part of the airflow can directly return to the air inlet cavity, and the other part of the airflow can flow into the air inlet cavity through the fourth cavity through the connecting port. By setting the connecting port, the path of the airflow flowing into the air inlet cavity is increased, and the resistance of the airflow flowing into the air inlet cavity can be reduced, so that more airflow flows to the air inlet cavity. At the same time, the airflow in the fourth cavity can flow into the air inlet cavity along the shortest path, so as to carry out the next cycle, thereby improving the utilization rate of the airflow in the fourth cavity and further improving the heat dissipation efficiency. In a possible design, the cabinet also includes an internal circulation fan, and the internal circulation fan is located at at least one end of the heat exchanger along the third direction.

[0024] In the above scheme, the internal circulation fan is located at at least one end of the heat exchanger along the third direction, and can drive the airflow in the air outlet cavity to flow into the third cavity, and then drive the airflow in the third cavity to flow into the heat exchanger cavity to exchange heat with the external airflow, and then drive the airflow in the heat exchanger cavity to flow into the fourth cavity, and finally drive the airflow in the fourth cavity to flow into the air inlet cavity. The internal circulation fan provides a driving force for the airflow, and can effectively drive the airflow inside the cabinet, so that the airflow can pass through each cavity space in turn, improve the utilization rate of the space inside the cabinet, and at the same time reduce the resistance of the airflow circulation, increase the flow rate of the airflow, and further improve the heat dissipation efficiency when the cabinet size remains unchanged.

[0025] In a possible design, the cabinet further includes an equipment fan, which is installed on the heat-generating device and is used to drive air flow from the air inlet cavity to the air outlet cavity.

[0026] In the above scheme, the device fan is located at at least one end of the heating device, and can drive the airflow in the air inlet cavity into the device cavity of the heating device, and can drive the airflow through the device cavity along the second direction, and then flow into the air outlet cavity from the other end of the heating device, providing a certain driving force for the airflow, promoting the flow of the airflow, so that the airflow can absorb the heat generated by the heating device and improve the heat dissipation efficiency.

[0027] In a possible design, blocking members are provided in the second cavity and the fourth cavity, and the blocking members are used to block the airflow from flowing in the direction of the air outlet cavity.

[0028] In the above solution, the blocking member can block the airflow flowing toward the air outlet cavity, so that the airflow flows more toward the air inlet cavity, thereby improving the utilization rate of the airflow in the second cavity and the fourth cavity.

[0029] In a possible design, the air inlet cavity is provided with a return air port and an air inlet, wherein, during the operation of the cabinet, regardless of whether a partition is provided, a portion of the airflow coming out of the heat exchanger cavity directly returns to the air inlet cavity, and the other portion enters the second through cavity and returns to the air inlet cavity through the return air port, that is, the airflow of the second cavity and the fourth cavity can enter the air inlet cavity through the return air port, and the airflow of the air inlet cavity can enter the equipment cavity through the air inlet.

[0030] In the above scheme, by providing the air inlet and the air return port, the flow path of the airflow in the air inlet cavity, the second cavity and the fourth cavity can be shortened, thereby improving the flow efficiency of the airflow.

[0031] In a possible design, one of the air inlet cavity and the air outlet cavity is located at the front side of the heat-generating device, and the other is located at the rear side of the heat-generating device.

[0032] In the above solution, the air inlet cavity and the air outlet cavity are respectively arranged at the front and rear ends of the heat generating device along the second direction, so that the airflow in the device cavity can fully absorb the heat of the heat generating device, thereby improving the heat dissipation capacity of the cabinet.

[0033] In one possible design, one of the first cavity and the second cavity is located at the top of the heat-generating device, and the other is located at the bottom of the heat-generating device; one of the third cavity and the fourth cavity is located at the top of the heat exchanger, and the other is located at the bottom of the heat exchanger; the first cavity and the third cavity are located on the same side, and the second cavity and the fourth cavity are located on the same side.

[0034] In the above scheme, the first cavity and the third cavity are located on the same side, and the second cavity and the fourth cavity are located on the same side, so that the flow path of the airflow from the first cavity to the third cavity and from the fourth cavity to the second cavity is the shortest, thereby improving the flow efficiency of the airflow.

[0060] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0061] In a specific embodiment, the present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0062] The embodiment of the present application provides a cabinet, which can be used to distribute power to electrical equipment, for example, it can be used to distribute power to 5G equipment. The cabinet can be an outdoor cabinet, including but not limited to a blade power cabinet, an equipment cabinet, a battery cabinet, etc. The cabinet in the embodiment of the present application is a blade power cabinet, and the air inlet and outlet form of the heat generating equipment is front airflow and rear airflow.

[0063] like Figure 1 As shown, the cabinet includes a shell 1, a heat generating device (not shown in the figure) and a heat exchanger (not shown in the figure), the heat generating device and the heat exchanger are both located in the shell 1, wherein the heat exchanger has a heat exchange core, the heat exchange core can be a downstream heat exchange core, a countercurrent heat exchange core or a cross-flow heat exchange core, and when the heat exchange core is working, there is no restriction on the direction of the heat exchange core panel, the heat exchange core can be rotated around its normal at any angle so that the panel faces the inside or outside of the cabinet. The heat generating device can be a device in the cabinet that generates heat during operation, and the solution in the present application is used to dissipate heat from the heat generating device.

[0064] like Figure 1 As shown, the heating device has a device cavity 2, and the heat exchanger has a heat exchanger cavity 3. The temperature of the device cavity 2 is relatively high, and the heat exchanger cavity 3 is used for heat exchange of heat exchange medium. The heating device and the heat exchanger are distributed along the first direction X; along the second direction Y, there are air inlet cavities 11 and air outlet cavities 12 between the two ends of the heating device and the housing 1 respectively; along the third direction Z, there are first cavities 13 and second cavities 14 between the two ends of the heating device and the housing 1 respectively, and there are third cavities 15 and fourth cavities 16 between the two ends of the heat exchanger and the housing 1 respectively. After the airflow enters the air inlet cavity 11, it can flow through the device cavity 2, the air outlet cavity 12, the first cavity 13, the third cavity 15, the heat exchanger cavity 3, and the fourth cavity 16, and enter the air inlet cavity 11 from the fourth cavity 16. The heat exchanger is used for heat exchange between the external airflow and the airflow entering the heat exchanger cavity 3 through the third cavity 15.

[0065] When the cabinet is working, the air flows from the air inlet chamber 11 into the equipment chamber 2 of the heating device along the second direction Y, and then passes through the equipment chamber 2 into the air outlet chamber 12, and while flowing in the equipment chamber 2, it can absorb the heat generated by the operation of the heating device, so that the operating temperature of the heating device is reduced; the airflow that has absorbed the heat of the heating device flows in the air outlet chamber 12 along the third direction Z to the end of the air outlet chamber 12 connected to the first chamber 13, and then flows into the first chamber 13, and flows into the third chamber 15 along the first direction X in the first chamber 13. At this time, the airflow in the third chamber 15 can flow into the heat exchanger chamber 3 of the heat exchanger along the third direction Z, exchange heat with the external cold air flow inside the heat exchanger chamber 3, and transfer heat to the external cold air flow; the airflow after heat exchange continues to flow along the third direction Z in the heat exchanger chamber 3 to the fourth chamber 16, and finally flows from the fourth chamber 16 to the air inlet chamber 11, so that the airflow can flow into the equipment chamber 2 again for the next cycle.

[0066] In this embodiment, the cabinet makes full use of the space inside the cabinet to set the air inlet cavity 11, the air outlet cavity 12, the first cavity 13, the second cavity 14, the third cavity 15 and the fourth cavity 16, optimizes the internal circulation air duct, expands the flow range of the airflow in the cabinet, and improves the space utilization inside the cabinet, so that the airflow flows through each cavity space in turn. Since the airflow can move along the first direction X and the third direction Z during one circulation process, a three-dimensional internal circulation air duct is formed, which can dissipate heat in multiple directions inside the cabinet, thereby improving the heat dissipation capacity of the cabinet.

[0067] The heat dissipation solution in the present application is mainly applicable to cabinets whose internal heat-generating devices have a front-to-rear air outlet. Of course, cabinets whose internal heat-generating devices have other air inlet and outlet forms can also adopt the heat dissipation solution of the present application.

[0068] It should be noted that the airflow flowing along the first direction X does not mean that the airflow flows in a straight line along the first direction X in each cavity, but means that the overall flow direction of the airflow flows from the first position to the second position, the first position and the second position are distributed along the first direction, and the flow path of the airflow can be a curved or straight path or any other shape. The flow of the airflow along the second direction Y and the third direction Z is the same.

[0069] In a specific embodiment, Figure 2As shown, the first cavity 13 and the third cavity 15 are connected to form a first through cavity 17, and the second cavity 14 and the fourth cavity 16 are connected to form a second through cavity 18. That is, along the third direction Z, the first through cavity 17 and the second through cavity 18 are respectively provided between the two ends of the heat generating device and the heat exchanger and the housing 1, and the first through cavity 17, the part located at one end of the heat generating device along the third direction Z is the first cavity 13, and the part located at one end of the heat exchanger along the third direction Z is the third cavity 15; the second through cavity 18, the part located at the other end of the heat generating device along the third direction Z is the second cavity 14, and the part located at the other end of the heat exchanger along the third direction Z is the fourth cavity 16.

[0070] In this embodiment, the first cavity 13 is connected with the third cavity 15, which reduces the resistance of the airflow when it flows from the first cavity 13 into the third cavity 15. At the same time, the space of the first through cavity 17 formed by the through connection is larger than the space of the first cavity 13 and the third cavity 15, so that the airflow accommodation space and flow space are increased, thereby increasing the amount of airflow entering the heat exchanger cavity 3 for heat exchange with the external airflow; similarly, the space of the second through cavity 18 formed by the second cavity 14 and the fourth cavity 16 is larger than the space of the second cavity 14 and the fourth cavity 16, so that the airflow accommodation space and flow space are increased, thereby increasing the amount of airflow entering the air inlet cavity 11 to continue the next cycle from the fourth cavity 16, thereby improving the utilization rate of the airflow in the first cavity 13 and the fourth cavity 16.

[0071] In another specific embodiment, Figure 1 As shown, the first cavity 13 is connected to the third cavity 15 through the air outlet cavity 12 , and the second cavity 14 is connected to the fourth cavity 16 .

[0072] In this embodiment, the air outlet cavity 12 is connected with the first cavity 13 and the third cavity 15 respectively. A part of the airflow in the air outlet cavity 12 flows directly from the air outlet cavity 12 into the third cavity 15, and the other part flows into the first cavity 13 along the second direction Y and then flows into the third cavity 15 along the first direction X. At this time, the resistance of the airflow flowing into the third cavity 15 is less than the resistance of flowing into the third cavity 15 along a single path (the airflow in the air outlet cavity 12 all flows directly into the third cavity 15 or all flows into the first cavity 13 along the second direction Y and then flows into the third cavity 15 along the first direction X), thereby promoting the airflow to flow from the air outlet cavity 12 into the third cavity 15; similarly, the second cavity 14 is connected with the fourth cavity 16, and a part of the airflow in the fourth cavity 16 can flow into the second cavity 14 along the first direction X, so that the airflow in the fourth cavity 16 is reduced, thereby reducing the resistance of the airflow when it flows from the fourth cavity 16 into the air inlet cavity 11, thereby promoting the airflow to flow from the fourth cavity 16 into the air inlet cavity 11.

[0073] Among them, connecting holes can be set between the first cavity 13 and the air outlet cavity 12, and between the third cavity 15 and the air outlet cavity 12, so that the first cavity 13 and the third cavity 15 are connected through the air outlet cavity 12, and connecting holes can be set between the second cavity 14 and the fourth cavity 16, so that the second cavity 14 and the fourth cavity 16 are connected, and the number, shape and cross-sectional area of ​​the above-mentioned connecting holes can be arbitrarily set according to actual conditions.

[0074] Specifically, Figure 1 As shown, the airflow in the heat exchanger cavity 3 can enter the fourth cavity 16 and the second cavity 14 , and enter the air inlet cavity 11 from the second cavity 14 .

[0075] In this embodiment, the airflow in the heat exchanger cavity 3 flows into the fourth cavity 16, and the second cavity 14 is connected to the fourth cavity 16. A part of the airflow in the fourth cavity 16 flows into the second cavity 14 along the first direction X and then flows into the air inlet cavity 11 along the second direction Y, and another part of the airflow flows directly from the fourth cavity 16 into the air inlet cavity 11. At this time, the resistance of the airflow flowing into the air inlet cavity 11 is less than the resistance of the airflow flowing into the air inlet cavity 11 along a single path (all the airflow in the fourth cavity 16 flows directly into the air inlet cavity 11), so that more airflow can flow from the fourth cavity 16 into the air inlet cavity 11.

[0076] In a specific embodiment, Figure 2 As shown, the cabinet further includes a partition 4 located between the heat generating device and the heat exchanger.

[0077] In this embodiment, the partition 4 is used to separate the heat-generating device from the heat exchanger. At the same time, each end surface of the partition 4 is respectively connected to the outer shell 1, thereby forming a mutually independent air inlet cavity 11, air outlet cavity 12, first cavity 13, second cavity 14, third cavity 15 and fourth cavity 16 inside the cabinet, making full use of the space inside the cabinet, allowing the airflow to pass through each cavity space in the cabinet in turn and circulate, thereby improving the utilization rate of the internal space of the cabinet.

[0078] Specifically, Figure 2 As shown, the partition plate 4 is provided with a communication port 41 , and the communication port 41 communicates the fourth cavity 16 with the air inlet cavity 11 .

[0079] In the present embodiment, during the operation of the cabinet, a part of the airflow can directly return to the air inlet chamber 11, and the other part of the airflow can flow into the air inlet chamber 11 through the connecting port 41 via the fourth cavity 16. By providing the connecting port 41, the path for the airflow to flow into the air inlet chamber 11 is increased, and the resistance of the airflow flowing into the air inlet chamber 11 can be reduced, so that more airflow can flow to the air inlet chamber 11. At the same time, the airflow in the fourth cavity 16 can flow into the air inlet chamber 11 along the shortest path, thereby performing the next cycle, thereby improving the utilization rate of the airflow in the fourth cavity 16 and further improving the heat dissipation efficiency.

[0080] In a specific embodiment, Figure 1 As shown, the cabinet further includes an internal circulation fan 5, and the internal circulation fan 5 is located at at least one end of the heat exchanger along the third direction Z.

[0081] In this embodiment, the internal circulation fan 5 is located at at least one end of the heat exchanger along the third direction Z, and can drive the airflow in the air outlet cavity 12 to flow into the third cavity 15, and then drive the airflow in the third cavity 15 to flow into the heat exchanger cavity 3 to exchange heat with the external airflow, and then drive the airflow in the heat exchanger cavity 3 to flow into the fourth cavity 16, and finally drive the airflow in the fourth cavity 16 to flow into the air inlet cavity 11. The internal circulation fan 5 provides a driving force for the airflow, and can effectively drive the airflow inside the cabinet, so that the airflow can pass through each cavity space in turn, improve the utilization rate of the space inside the cabinet, and at the same time reduce the resistance of the internal circulation of the airflow, increase the flow rate of the airflow, and further improve the heat dissipation efficiency when the cabinet size remains unchanged.

[0082] The internal circulation fan 5 can be located in any cavity space of the air inlet cavity 11, the air outlet cavity 12, the equipment cavity 2, the heat exchanger cavity 3, the first cavity 13, the second cavity 14, the third cavity 15, and the fourth cavity 16 to drive the airflow. Figure 1 As shown, in this embodiment, the internal circulation fan 5 is located in the fourth cavity 16 connected to one end of the heat exchanger along the third direction Z.

[0083] Specifically, in this embodiment, the cabinet may include an internal circulation fan, and the internal circulation fan 5 has a blowing function and an exhaust function. When the airflow flows from the equipment cavity 2 into the air outlet cavity 12, the internal circulation fan 5 can blow the airflow in the air outlet cavity 12 to the first cavity 13, so that the airflow quickly flows into the first cavity 13 along the third direction Z; when the airflow flows from the first cavity 13 to the third cavity 15, the internal circulation fan 5 can extract the airflow in the third cavity 15 to the heat exchanger cavity 3, so that the airflow quickly flows into the heat exchanger cavity 3 along the third direction Z. Alternatively, the cabinet may also include two relatively arranged internal circulation fans, both of which have a blowing function or an exhaust function, so that the corresponding internal circulation fans can be turned on or off as needed to make the airflow flow along a preset path.

[0084] In a specific embodiment, the cabinet further includes an equipment fan (not shown in the figure), which is installed on the heat generating device and is used to drive the air flow from the air inlet cavity 11 to the air outlet cavity 12 .

[0085] In this embodiment, the device fan is located at at least one end of the heating device, and can drive the airflow in the air inlet cavity 11 into the device cavity 2 of the heating device, and can drive the airflow through the device cavity 2 along the second direction Y, and then flow into the air outlet cavity 12 from the other end of the heating device, providing a certain driving force for the airflow, promoting the flow of the airflow, so that the airflow can absorb the heat generated by the heating device and improve the heat dissipation efficiency.

[0086] In a specific embodiment, Figure 1 As shown, a blocking member 141 is disposed in the second cavity 14 and the fourth cavity 16 , and the blocking member 141 is used to block the airflow from flowing in the direction of the air outlet cavity 12 .

[0087] In this embodiment, the blocking member 141 is located at one end of the second cavity 14 and the fourth cavity 16 away from the air inlet cavity 11 and close to the air outlet cavity 12. When the airflow entering the second cavity 14 and the fourth cavity 16 flows toward the air outlet cavity 12 along the second direction Y, the blocking member 141 can block the airflow from continuing to flow toward the air outlet cavity 12, so that the airflow changes direction and flows toward the air inlet cavity 11. The blocking member 141 can block the airflow flowing toward the air outlet cavity 12, so that more airflow flows toward the air inlet cavity 11, thereby improving the utilization rate of the airflow in the second cavity 14 and the fourth cavity 16.

[0088] The blocking member 141 may specifically be a metal baffle, foam or other wind-blocking structures.

[0089] In a specific embodiment, Figure 2 As shown, the air inlet chamber 11 is provided with a return air port 111 and an air inlet 112, wherein, during the operation of the cabinet, regardless of whether a partition 4 is provided, a portion of the airflow coming out of the heat exchanger chamber 3 directly returns to the air inlet chamber 11, and the other portion enters the second through chamber 18, and returns to the air inlet chamber 11 through the return air port 111, that is, the airflow of the second cavity 14 and the fourth cavity 16 can enter the air inlet chamber 11 through the return air port 111, and the airflow of the air inlet chamber 11 can enter the equipment cavity 2 through the air inlet 112.

[0090] In this embodiment, the airflow in the air inlet cavity 11 enters the equipment cavity 2 through the air inlet 112, and the airflow in the second cavity 14 and the fourth cavity 16 returns to the air inlet cavity 11 through the return air port 111, and then flows from the return air port 111 to the air inlet 112 along the third direction Z to start the next cycle of the airflow. By providing the air inlet 112 and the return air port 111, the flow path of the airflow in the air inlet cavity 11, the second cavity 14 and the fourth cavity 16 can be shortened, and the flow efficiency of the airflow can be improved.

[0091] It should be noted that the cabinet in this application can be of any shape, such as Figure 1 and Figure 2 In the embodiment shown, the cabinet can be a rectangular parallelepiped structure, in which the heat exchanger and the heating device are both vertical structures, and the two are distributed along the thickness direction of the cabinet. Based on this, in this embodiment, the first direction X can specifically be the width direction of the cabinet, the second direction Y can specifically be the length direction of the cabinet, and the third direction Z can specifically be the height direction of the cabinet. When the shape of the cabinet, the arrangement direction of the heat exchanger and the heating device are different, the above-mentioned first direction X, second direction Y and third direction Z will also change accordingly. When the cabinet is arranged as shown in the figure Figure 1 When installed in the orientation shown, the "front side" refers to the side facing the staff along the width direction (first direction X), and the "rear side" refers to the side facing away from the staff along the width direction (first direction X); the "left side" refers to the side located on the left hand side of the staff along the length direction (second direction Y) when the staff faces the cabinet, and the "right side" refers to the side located on the right hand side of the staff along the length direction (second direction Y) when the staff faces the cabinet; the "top" refers to the top side of the cabinet, and the "bottom" refers to the bottom side of the cabinet, that is, the "top" and "bottom" refer to the opposite sides of the cabinet along the height direction (third direction Z).

[0092] In a specific embodiment, Figure 1 As shown, one of the air inlet cavity 11 and the air outlet cavity 12 is located at the front side of the heating device, and the other is located at the rear side of the heating device. When the air inlet cavity 11 is located at the front side of the heating device, the air outlet cavity 12 is located at the rear side of the heating device; when the air inlet cavity 11 is located at the rear side of the heating device, the air outlet cavity 12 is located at the front side of the heating device.

[0093] In this embodiment, the air inlet cavity 11 and the air outlet cavity 12 are respectively connected to the equipment cavity 2 of the heating device, and the air inlet cavity 11 can provide airflow for the equipment cavity 2, so that the airflow flows into the equipment cavity 2 to absorb the heat generated by the heating device, and the air outlet cavity 12 can provide space for the airflow flowing out of the equipment cavity 2 and guide the airflow to the next cavity space. The air inlet cavity 11 and the air outlet cavity 12 are respectively arranged at the front and rear ends of the heating device along the second direction Y, so that the airflow in the equipment cavity 2 can fully absorb the heat of the heating device, thereby improving the heat dissipation capacity of the cabinet.

[0094] In a specific embodiment, Figure 1 As shown, one of the first cavity 13 and the second cavity 14 is located at the top of the heat-generating device, and the other is located at the bottom of the heat-generating device; one of the third cavity 15 and the fourth cavity 16 is located at the top of the heat exchanger, and the other is located at the bottom of the heat exchanger; the first cavity 13 and the third cavity 15 are located on the same side, and the second cavity 14 and the fourth cavity 16 are located on the same side. When the first cavity 13 and the third cavity 15 are located at the top of the cabinet, the second cavity 14 and the fourth cavity 16 are located at the bottom of the cabinet; when the first cavity 13 and the third cavity 15 are located at the bottom of the cabinet, the second cavity 14 and the fourth cavity 16 are located at the top of the cabinet.

[0095] In this embodiment, the first cavity 13 and the second cavity 14 are respectively located at the two ends of the heat generating device along the third direction Z, and the third cavity 15 and the fourth cavity 16 are respectively located at the two ends of the heat exchanger along the third direction Z, which can expand the flow range of the airflow and improve the utilization rate of the space in the cabinet. At the same time, when the third cavity 15 and the fourth cavity 16 are respectively located at the two ends of the heat exchanger, the airflow flows from the third cavity 15 into the heat exchanger cavity 3 of the heat exchanger, and then flows from the heat exchanger cavity 3 into the fourth cavity 16. The path taken by the airflow is the longest, and the airflow can better exchange heat with the external airflow. The first cavity 13 and the third cavity 15 are located on the same side, and the second cavity 14 and the fourth cavity 16 are located on the same side, so that the flow path of the airflow from the first cavity 13 to the third cavity 15 and from the fourth cavity 16 to the second cavity 14 is the shortest, which improves the flow efficiency of the airflow.

[0096] Specifically, Figure 1 and Figure 2As shown, when the cooling system of the cabinet in the embodiment of the present application is working, the airflow flows from the air inlet chamber 11 into the equipment chamber 2, and after absorbing the heat of the heating equipment, flows along the second direction Y into the air outlet chamber 12 located at the other end of the heating equipment, and then, driven by the internal circulation fan 5, the airflow flows along the third direction into the first chamber 13, and then flows into the third chamber 15 on the same side as the first chamber 13. After the airflow in the third chamber 15 is driven by the internal circulation fan 5, it flows along the third direction Z into the heat exchanger chamber 3, and exchanges heat with the external airflow in the heat exchanger chamber 3. The airflow after heat exchange continues to flow along the third direction Z into the fourth chamber 16 located at the other end of the heat exchanger under the drive of the internal circulation fan 5, and then flows into the second chamber 14 on the same side as the fourth chamber 16. Finally, driven by the internal circulation fan 5, the airflow in the second chamber 14 flows back to the air inlet chamber 11 for the next cycle.
