[0024] Reference Figure 1-2 The utility model proposes a mobile outdoor communication base station multi-connection cabinet heat exchange device, comprising: a shell 1, a phase change heat exchange core 2, an internal circulation fan 3 and an external circulation fan 4, wherein:

[0025] The shell 1 has an inner circulation cavity 11 and an outer circulation cavity 12 inside. The opposite side walls of the inner circulation cavity 11 are respectively provided with an air supply port a and an air return port b, and the opposite side walls of the outer circulation cavity 12 are respectively provided with an air inlet c and an air outlet d. The phase change heat core 2 is installed in the shell 1, and the evaporation end of the phase change heat core 2 is located in the inner circulation cavity 11, and the inner circulation cavity 11 is divided into an air supply side located on the side where the evaporation end is close to the air supply port a and a return air side located on the side where the evaporation end is close to the return air port b; the condensation end of the phase change heat core 2 is located in the outer circulation cavity 12, and the outer circulation cavity 12 is divided into an air inlet side located on the side where the condensation end is close to the air inlet c and an air outlet side located on the side where the condensation end is close to the air outlet d. The inner circulation fan 3 is located in the air supply side and is installed at the air supply port a; the outer circulation fan 4 is located outside the shell 1 and is installed at the air outlet d.

[0026] Reference Figure 3 When in use, the return air port b and air supply port a of the heat exchange equipment are connected to each cabinet in the multi-unit cabinet through pipes in advance to form a complete internal circulation air duct loop, so that the high-temperature air in each cabinet can enter the phase change heat core 2 from the air supply port a under the guidance of the internal circulation fan 3 and re-enter each cabinet after being cooled by the phase change heat core 2 to form low-temperature air, thereby forming an internal circulation; while the low-temperature air from the outside passes through the air inlet c, is sucked into the condensation end of the phase change heat core 2, and is converted into hot air after completing the heat exchange and discharged from the air outlet d, thereby forming an external circulation. The external circulation and the internal circulation are respectively in two independent environments, so that dust and foreign matter from the outside can be prevented from invading the cabinet through the circulation, thereby achieving a dustproof and waterproof effect.

[0027] This achieves the purpose of unified heat dissipation and cooling of multi-connected cabinets, reduces the temperature difference in each cabinet, improves the wind field in the cabinet, improves the cooling efficiency, makes the temperature field in the cabinet uniform, avoids the local "heat island" phenomenon, and ensures that the communication equipment is always in a good operating environment. In addition, the high-temperature air in the cabinet is completely isolated from the outside air during the entire heat exchange process, which can effectively ensure the air quality in the cabinet.

[0028] In addition, in this embodiment, the inner wall of the inner circulation cavity 11 is covered with a thermal insulation layer, so that the internal and external structural components of the inner circulation cavity 11 have a cold bridge design, thereby enhancing the thermal insulation performance.

[0029] Furthermore, the heat-insulating layer located on the inner wall of the inner circulation cavity 11 is composed of a rubber-plastic heat-insulating plate covering the inner wall.

[0030] Therefore, in this embodiment, the air supply port a and the air inlet c are located on the same side of the shell 1 , and the air return port b and the air outlet d are located on the other side of the shell 1 .

[0031] In this embodiment, the side of one side of the external circulation cavity 12 is densely covered with holes to form an air inlet c, and a dustproof net is provided at the air inlet c. The external ambient air passes through the dustproof net of the air inlet c, is sucked into the condensing end of the phase change heat core 2, and is converted into hot air and discharged from the air outlet d. The setting of the dustproof net can effectively prevent external dust and debris from entering the external circulation cavity 12, and is easy to disassemble and clean, and convenient for maintenance.

[0032] In this embodiment, a mounting bracket 6 is provided at the bottom of the shell 1. When in use, the heat exchange device is installed on the top of the cabinet through the mounting bracket 6 to reduce the occupied space and facilitate the extraction of high-temperature air.

[0033] In this embodiment, an electric control box 5 is installed at one end of the housing 1 ; a temperature sensor is arranged inside the housing 1 .

[0034] In this embodiment, a bulkhead 7 is provided inside the shell 1 , and the shell 1 is partitioned by the bulkhead 7 to form an inner circulation cavity 11 located on one side of the bulkhead 7 and an outer circulation cavity 12 located on the other side of the bulkhead 7 .

[0035] In this embodiment, the housing 1 includes a lower box body and an upper cover plate detachably mounted on the lower box body to facilitate inspection and maintenance of the internal components of the housing 1 .

[0036] In addition, the external circulation fan 4 in this embodiment is an axial flow fan, which is smaller in size and can produce a higher airflow output with lower energy consumption.

[0037] As can be seen from the above, the structural design of the utility model gives it the advantage of a large circulating air volume, so that the purpose of uniform heat dissipation and cooling of multi-connected cabinets can be achieved, thereby reducing the temperature difference in each cabinet, improving the wind field in the cabinet, improving the cooling efficiency, making the temperature field in the cabinet uniform, and effectively avoiding the local "heat island" phenomenon, ensuring that the communication equipment is always in a good operating environment. In addition, when in use, its return air port b and air supply port a are respectively connected to a certain number of cabinets, and the high-temperature air in the cabinet is sent into the cabinet after being cooled by the heat exchange device. The whole process is completely isolated from the outside air, which can effectively ensure the air quality in the cabinet. In addition, the heat exchange device does not affect the operation of the cabinet door air conditioner, and can greatly reduce the operating time of the cabinet door air conditioner, thereby extending the service life of the cabinet door air conditioner and reducing maintenance and replacement costs. And there are few restrictions on the installation method, which can be fully applied to various environments.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
