[0045] The embodiments of the present disclosure provide an air-cooled cabinet, as Figures 1 to 8 shown, the air-cooled cabinet includes a cabinet body 100 and a heat exchange mechanism. The cabinet body 100 includes a cabinet shell 110 with an opening and a cabinet cover 130 covering the opening. The cabinet shell 110 and the cabinet cover 130 enclose a cooling air duct 140. A plurality of air return openings and air outlet groups communicating with the cooling air duct 140 are provided on the cabinet shell 110 and / or the cabinet cover 130. Any air return opening and air outlet group is used to communicate with a corresponding chassis. At least part of the heat exchange mechanism is arranged in the cooling channel and is connected to the cabinet body 100. The heat exchange mechanism is used to cool the air and make the air circulate between the chassis and the cooling air duct 140.

[0046] With this alternative embodiment, the cabinet housing 110 and the cabinet cover 130 enclose a cooling air duct 140, and the cabinet housing 110 and / or the cabinet cover 130 are provided with a plurality of air return openings and air outlet groups. Each air return opening and air outlet group includes a corresponding air return opening 141 and an air outlet 142. A chassis can communicate with the cooling air duct 140 through the air return opening 141 and the air outlet 142 within a corresponding air return opening and air outlet group. At least part of the heat exchange mechanism is disposed within the cooling air duct 140, and the heat exchange mechanism is used to cool the air and cause the air to circulate within the chassis and the cooling air duct 140. In this way, the cooled air can circulate within the chassis and the cooling air duct 140 through the air return opening and air outlet group to cool the electronic devices placed within the chassis, enabling the electronic devices to operate within a suitable temperature range.

[0047] In this embodiment, a plurality of air return openings and air outlet groups are provided on the cabinet housing 110 and / or the cabinet cover 130. A plurality of chassis can communicate with the heat exchange air duct through the corresponding air return openings and air outlet groups to centrally cool the plurality of chassis. This not only facilitates the installation of the air-cooled unit, reduces production costs, but also facilitates the inspection and maintenance of the air-cooled cabinet, improving the reliability and stability of the air-cooled cabinet in use.

[0048] Moreover, the heat exchange mechanism is disposed within the cooling air duct 140 of the cabinet body 100. The cooling air duct 140 communicates with the chassis through the air return opening 141 and the air outlet 142 group, reducing the situation where the heat exchange mechanism is disposed within the chassis and occupies the space of the chassis. The air circulates within the chassis and the cooling air duct 140, reducing the exchange with the outside air, thereby reducing the situation where external dust and impurities enter the chassis, improving the dust-proof effect of the air-cooled cabinet.

[0049] The cabinet cover 130 covers the opening of the cabinet housing 110. The cabinet cover 130 can open or close the opening of the cabinet housing 110, facilitating the installation of the heat exchange mechanism within the cabinet housing 110 and facilitating the maintenance of the heat exchange mechanism by the staff, reducing the installation and maintenance difficulty.

[0050] In some alternative embodiments, the cabinet housing 110 includes a top plate, a bottom plate, and a plurality of side walls connecting the top plate and the bottom plate. Different air return openings and air outlet groups are located on different side walls.

[0051] In this embodiment, a plurality of air return openings and air outlet groups are provided on the cabinet housing 110 and / or the cabinet cover 130. When a plurality of air return openings and air outlet groups are provided on the cabinet housing 110, different air return openings and air outlet groups are located on different side walls. In this way, the chassis communicated with the air return openings and air outlet groups provided on the cabinet housing 110 can be arranged on the corresponding side wall of the cabinet housing 110. The plurality of chassis are respectively located on different side walls of the cabinet body 100, so as to provide sufficient installation space for the chassis, be able to cool a plurality of chassis simultaneously, reduce the occurrence of interference between the plurality of chassis, improve the reliability of the installation of the air-cooled cabinet and the chassis, and facilitate the connection between the chassis and the air-cooled cabinet.

[0052] Exemplarily, as Figure 1 、 Figure 2 and Figure 5 shown, the plurality of side walls include a first side wall opposite to the cabinet cover 130, and one air return opening and one air outlet group are respectively provided on the first side wall and the cabinet cover 130.

[0053] In this embodiment, the plurality of air return openings and air outlet groups can all be provided on the plurality of side walls of the cabinet housing 110, or a part of them can be provided on the side walls of the cabinet housing 110 and the other part can be provided on the cabinet cover 130.

[0054] For example, different air return openings and air outlet groups can be respectively provided on the cabinet cover 130 and the side walls of the cabinet housing 110. One air return opening and one air outlet group are provided on the cabinet cover 130, and the plurality of side walls of the cabinet housing 110 include a first side wall opposite to the cabinet cover 130, and another air return opening and another air outlet group are provided on the first side wall. In this way, two chassis can be respectively arranged on opposite sides of the air-cooled cabinet, so that the chassis can be arranged in the same direction, improving the layout rationality and neatness of the air-cooled unit.

[0055] In some alternative embodiments, as Figures 1 to 4 shown, the air return opening 141 and the air outlet 142 in any air return opening and air outlet group are arranged along the height direction of the side wall.

[0056] For example, the air return opening 141 is provided above the air outlet 142, or the air return opening 141 is provided below the air outlet 142. In this way, air flows along the height direction of the side wall in the cooling air duct 140, so as to optimize the air flow path and reduce the occurrence of air staying or generating vortices in the cooling air duct 140 or the chassis.

[0057] Optionally, the air return opening 141 is provided below the air outlet 142. In this way, after the relatively cold air flows into the chassis from the air outlet 142, the air not only flows downward under the drive of the fan 200, but also can diffuse downward under the influence of its own gravity, so as to facilitate the circulation of air in the cooling air duct 140 and the chassis and improve the cooling effect of the air-cooled cabinet.

[0058] In some alternative embodiments, such as Figures 6 to 8 shown, the heat exchange mechanism includes a blower 200 disposed at the air outlet 142 and a heat exchanger 300 disposed in the cooling air duct 140. The blower 200 is configured to circulate air within the chassis and the cooling air duct 140, and the heat exchanger 300 is configured to cool the air.

[0059] In this embodiment, the heat exchanger 300 is disposed in the cooling air duct 140 and can cool the air within the cooling air duct 140. The blower 200 is disposed at the air outlet 142, and the blower 200 can drive the air to circulate between the cooling air duct 140 and the chassis, so as to drive the cooled air in the cooling air duct 140 into the chassis to cool the electronic devices within the chassis.

[0060] Optionally, as Figures 4 to 8 shown, the heat exchange mechanism further includes a refrigerant delivery pipe group 400. The refrigerant delivery pipe group 400 is connected to the heat exchanger 300 and is configured to deliver refrigerant to the heat exchanger 300.

[0061] Optionally, the main liquid inlet end and the main liquid outlet end of the refrigerant delivery pipe group 400 are communicated with an external water chiller, and the external water chiller provides low-temperature refrigerant to the refrigerant delivery pipe group 400.

[0062] Optionally, the main liquid inlet end of the refrigerant delivery pipe group 400 is communicated with a throttling device of the heat exchange system, and the main liquid outlet end of the refrigerant delivery pipe group 400 is communicated with a compressor of the heat exchange system. The heat exchanger 300 is equivalent to an evaporator in the heat exchange system to cool the air in the cooling air duct 140.

[0063] In some alternative embodiments, a semiconductor heat exchanger can also be used. The principle of the semiconductor heat exchanger is mainly based on the Peltier effect and the thermoelectric effect, and it is a device that uses the thermoelectric effect of semiconductor materials to achieve heat transfer.

[0064] In some alternative embodiments, such as Figures 5 to 8 shown, the cabinet 100 further includes a partition 120 disposed in the cooling air duct 140 and connected to the cabinet shell 110. The partition 120 divides the cooling air duct 140 into a plurality of sub-air ducts 143, and each sub-air duct 143 corresponds to a return air outlet and an air outlet group.

[0065] In this embodiment, the partition 120 is disposed in the cooling air duct 140 to divide the cooling air duct 140 into a plurality of sub-air ducts 143, and each sub-air duct 143 corresponds to a return air outlet and an air outlet group. In this way, a sub-air duct 143 is communicated with a chassis through a return air outlet and an air outlet group, and cold air can flow between the corresponding sub-air duct 143 and the chassis, so as to optimize the air flow path, reduce the situation where multiple air flow paths in the cooling air duct 140 are mixed with each other and the air resistance increases, and improve the cooling effect on the chassis.

[0066] And when setting the partition 120, the number and size of the sub-air ducts 143 can be adjusted according to the cooling requirements of the electronic devices in different chassis, improving the versatility of the air-cooled cabinet.

[0067] Optionally, multiple cooling air ducts 140 are arranged in sequence along the transverse direction of the cabinet body 100. This can reduce the occurrence of mutual interference between multiple sub-air ducts 143, facilitate the setting of the sub-air ducts 143 and the installation of the fans 200 and heat exchangers 300, and reduce the installation production cost.

[0068] In some alternative embodiments, multiple sub-air ducts 143 share one heat exchanger 300. In this way, one heat exchanger 300 can cool the air in multiple sub-air ducts 143, integrate the heat exchanger 300, reduce the number of heat exchangers 300 used, and reduce the cost of the air-cooled cabinet.

[0069] Optionally, the heat exchanger 300 is located in multiple sub-air ducts 143. The heat exchanger 300 can be arranged at the bottom or top of multiple sub-air ducts 143, or the partition 120 is provided with an installation opening, and the heat exchanger 300 passes through the installation hole and is located in multiple sub-air ducts 143.

[0070] In some alternative embodiments, the number of heat exchangers 300 is multiple, and multiple heat exchangers 300 are arranged in one-to-one correspondence with multiple sub-air ducts 143. In this way, each sub-air duct 143 is provided with one heat exchanger 300, which can independently cool the air in the sub-air duct 143.

[0071] Optionally, the heat exchanger 300 is arranged at the air return opening 141 corresponding to the sub-air duct 143.

[0072] In this embodiment, the heat exchanger 300 is arranged at the air return opening 141, so that the air flowing back into the cooling air duct 140 through the air return opening 141 can pass through the heat exchanger 300, increasing the contact area between the air and the heat exchanger 300, improving the cooling effect of the heat exchanger 300 on the air, and thus improving the cooling effect of the air-cooled cabinet.

[0073] Optionally, the outer shell of the heat exchanger 300 is attached to the circumferential side wall of the air return opening 141.

[0074] Optionally, there is a first interval between the fan 200 and the side wall of the cabinet body 100 facing away from the air outlet 142;

[0075] In this embodiment, there is a first interval between the fan 200 and the side wall of the cabinet body 100 facing away from the air outlet 142, and air can enter the fan 200 through the first interval. The fan 200 can be an axial flow fan 200, reducing the cost of the air-cooled mechanism.

[0076] Optionally, there is a second gap between the heat exchanger 300 and the side wall of the cabinet body 100 facing away from the return air inlet 141.

[0077] With this optional embodiment, there is a second gap between the heat exchanger 300 and the side wall of the cabinet body 100 facing away from the return air inlet 141, and there is a first gap between the blower 200 and the side wall of the cabinet body 100 facing away from the air outlet 142. The first gap and the second gap are located on the same side of the sub-air duct 143. After the air flows through the heat exchanger 300 from the return air inlet 141, it flows into the second gap, then flows from the second gap along one side of the cooling air duct 140 into the first gap, and then passes through the first gap and flows through the blower 200, and then flows into the chassis from the air outlet 142. In this way, the flow path of the air can be optimized, the resistance and eddy current phenomena in the air flow can be reduced, and the stability and reliability of the cooling of the air cooling mechanism can be improved.

[0078] Optionally, a plurality of heat exchangers 300 are connected in parallel through a refrigerant delivery pipe group 400.

[0079] With this optional embodiment, a plurality of heat exchangers 300 are connected in parallel through the refrigerant delivery pipe group 400, which can improve the uniformity of the distribution of the refrigerant among the heat exchangers 300 and improve the cooling effect of the air-cooled cabinet on a plurality of chassis.

[0080] In some optional embodiments, such as Figure 3 , Figures 5 to 8 shown, the refrigerant delivery pipe group 400 includes a main liquid inlet pipe 410, a main liquid outlet pipe 420, a plurality of sub-liquid inlet pipes 430 and a plurality of sub-liquid outlet pipes 440. The liquid inlet ends of the plurality of sub-liquid inlet pipes 430 are all communicated with the main liquid inlet pipe 410, the liquid outlet ends of the plurality of sub-liquid inlet pipes 430 are respectively communicated with the liquid inlet ports of the corresponding heat exchangers 300, the liquid inlet ends of the plurality of sub-liquid outlet pipes 440 are respectively communicated with the liquid outlet ports of the corresponding heat exchangers 300, and the liquid outlet ends of the plurality of sub-liquid outlet pipes 440 are all communicated with the main liquid outlet pipe 420.

[0081] In this embodiment, the liquid inlet ends of multiple sub-liquid inlet pipes 430 are all connected to the main liquid inlet pipe 410, and the refrigerant in the main liquid inlet pipe 410 can flow into the multiple sub-liquid inlet pipes 430 respectively. The liquid outlet ends of the multiple sub-liquid inlet pipes 430 are respectively connected to the liquid inlet ports of the corresponding heat exchangers 300. The refrigerant in the sub-liquid inlet pipes 430 can enter the heat exchangers 300 connected to the sub-liquid inlet pipes 430 to exchange heat with air in the heat exchangers 300. The liquid inlet ends of the multiple sub-liquid outlet pipes 440 are respectively connected to the liquid outlet ports of the corresponding heat exchangers 300. After the refrigerant exchanges heat in the heat exchangers 300, it flows out of the heat exchangers 300 and into the sub-liquid outlet pipes 440 connected to the heat exchangers 300. The liquid outlet ends of the multiple sub-liquid outlet pipes 440 are all connected to the main liquid outlet pipe 420, and the refrigerant in the multiple sub-liquid outlet pipes 440 all flows into the main liquid outlet pipe 420 and flows out through the main liquid outlet pipe 420. In this way, the multiple heat exchangers 300 are connected in parallel, improving the uniformity of refrigerant distribution in the multiple heat exchangers 300 and enhancing the cooling effect of the air-cooling mechanism.

[0082] Optionally, the partition 120 is provided with avoidance holes. The main liquid inlet pipe 410, the main liquid outlet pipe 420, one sub-liquid inlet pipe 430, and one sub-liquid outlet pipe 440 are located in one sub-air duct 143, and the other sub-liquid inlet pipes 430 and the other sub-liquid outlet pipes 440 pass through the avoidance holes and are located in other sub-air ducts 143 to be connected to the corresponding heat exchangers 300.

[0083] In some alternative embodiments, as Figure 7 and Figure 8 shown, the air-cooled cabinet further includes a temperature detection device and a controller 500. The temperature detection device is arranged at the air return port 141 for detecting the air return temperature. The controller 500 is connected to the temperature detection device and the fan 200. The controller 500 can receive the air return temperature and adjust the rotation speed of the fan 200 according to the magnitude of the air return temperature.

[0084] In this embodiment, the temperature detection device is arranged at the air return port 141. The air in the chassis flows into the cooling air duct 140 through the air return port 141, and the temperature at the air return port 141 is the temperature inside the chassis.

[0085] The controller 500 is connected to the temperature detection device and the fan 200, that is, the signal output end of the temperature detection device is electrically connected to the signal receiving end of the controller 500, and the signal output end of the controller 500 is electrically connected to the signal receiving end of the fan 200. The controller 500 can receive the air return temperature and adjust the rotation speed of the fan 200 according to the magnitude of the air return temperature, that is, the controller 500 can output a signal to the fan 200 according to the temperature inside the chassis to adjust the rotation speed of the fan 200, so as to adjust the cooling effect on the chassis through the air volume, improve the cooling effect on the chassis, and save energy consumption.

[0086] Exemplarily, when the return air temperature is less than the first preset temperature, the controller 500 is configured to control the fan 200 to operate at the first rotational speed.

[0087] When the return air temperature is greater than or equal to the first preset temperature and less than the second preset temperature, the controller 500 is configured to control the fan 200 to operate at the second rotational speed.

[0088] When the return air temperature is greater than or equal to the second preset temperature, the controller 500 is configured to control the fan 200 to operate at the third rotational speed.

[0089] Wherein, the third rotational speed is greater than the second rotational speed, and the second rotational speed is greater than the first rotational speed.

[0090] By adopting this alternative embodiment, when the return air temperature is relatively low, that is, the temperature inside the chassis is relatively low and the cooling capacity required by the chassis is relatively small, the rotational speed of the fan 200 can be reduced at this time to reduce the energy consumption of the fan 200. When the return air temperature is relatively high, that is, the temperature inside the chassis is relatively high and the amount of temperature reduction required by the chassis is relatively large, the rotational speed of the fan 200 can be increased at this time to increase the cooling capacity of the chassis and improve the temperature reduction effect on the chassis.
