[0034] As shown in Figure 1 In the embodiment, the software server cabinet comprises a cabinet body 10 and an external air circulation box 20.

[0035] The cabinet body 10 is used for placing software servers, and a plurality of shelves 15 are arranged in the cabinet body 10, and the shelves 15 are used for placing servers and related electronic equipment. The cabinet body 10 comprises four vertical columns located at four corners of a rectangle, connecting cross beams are arranged between adjacent two vertical columns, and metal skins are arranged on the outer sides of the vertical columns. The vertical columns are provided with a plurality of shelves 15 in the height direction. The shelves 15 can be formed by welding or splicing metal profiles such as angle steels. The cabinet body 10 is provided with a cabinet door 11, a first air inlet hole 12, a second air inlet hole 13 and a first cooling fan 14. The software server cabinet further comprises the external air circulation box 20. The cabinet door 11 is arranged on the front side of the cabinet body 10, as shown in Figure 2 The side of the front of the cabinet body 10 is provided with a hinge 111, and the cabinet door 11 is installed on the cabinet body 10 through the hinge 111. The inside of the cabinet body 10 can be accessed by opening the cabinet door 11, so that the inspection and maintenance are facilitated. A transparent glass window or a display can be arranged on the cabinet door 11. The inside of the cabinet body 10 can be seen through the glass window without opening the cabinet door 11. The display can be used for displaying the temperature, humidity and other environmental parameters in the cabinet body 10. As shown in Figure 1 The first air inlet hole 12 can be arranged at the top of the cabinet body 10, so that the horizontal volume of the cabinet body 10 is saved. Figure 2 Figure 3 The first cooling fan 14 can be arranged at the middle lower part of the back of the cabinet body 10. Air enters the cabinet body 10 from the first air inlet hole 12 at the top of the cabinet body 10, and hot air in the cabinet body 10 is discharged from the bottom of the cabinet body 10 through the first cooling fan 14. Figure 1 Figure 2 In the embodiment, the first air inlet hole 12 is a grating type air inlet hole, the second air inlet hole 13 is a circular hole or a square hole, and an air filter screen is arranged on the inner side of the first air inlet hole 12.

[0036] As shown in Figure 1 , Figure 3 and​​Figure 4 As shown, the external air circulation box 20 is provided with a return pipe 24 and a heat exchanger, the return pipe 24 connects the exhaust end of the first cooling fan 14 and the air inlet end of the second air inlet hole 13, the heat exchanger includes a first cooling fin 21 arranged in the return pipe 24 and a second cooling fin 22 arranged outside the return pipe 24, and a metal heat conduction pipe 25 connecting the first cooling fin 21 and the second cooling fin 22; the second cooling fin 22 is provided with a second cooling fan 23.

[0037] As shown in Figure 1 and Figure 2 In this embodiment, the second air inlet hole 13 is arranged on the side of the cabinet 10, and the second air inlet hole 13 can be located in the middle of the cabinet 10, and the second air inlet hole 13 is connected to the exhaust end of the first cooling fan 14 through the return pipe 24, so that the hot air discharged by the first cooling fan 14 is cooled by the heat exchanger and then returns to the cabinet 10 through the second air inlet hole 13. The first cooling fin 21 and the second cooling fin 22 can be made of high thermal conductivity metals or alloys such as aluminum, aluminum alloy, copper or copper alloy. The first cooling fin 21 absorbs heat from the hot air and its temperature rises, and the absorbed heat is transferred to the second cooling fin 22 through the metal heat conduction pipe 25, and the second cooling fin 22 spreads the heat to the outside air. Therefore, the heat in the cabinet 10 can be discharged to the outside of the cabinet 10 through the above-mentioned heat exchanger. In order to improve the heat exchange efficiency between the second cooling fin 22 and the air, the surface of the second cooling fin 22 is provided with a second cooling fan 23, and the external air is blown to the second cooling fin 22 through the second cooling fan 23, thereby taking away the heat of the second cooling fin 22.

[0038] In this embodiment, the hot air discharged by the first cooling fan can be partially or entirely cooled by the heat exchanger and then returned to the cabinet 10. In an embodiment, in order to better control the humidity inside the cabinet 10 and the cooling efficiency of the cabinet 10, a Y-shaped three-way pipe (of course, in other embodiments, a T-shaped three-way pipe can also be used to replace the Y-shaped three-way pipe) is arranged at the exhaust end of the first cooling fan 14, the Y-shaped three-way pipe includes a main pipe, a first branch pipe and a second branch pipe, the main pipe is connected with the exhaust end of the first cooling fan 14, and the first branch pipe is connected with the return pipe 24.

[0039] The hot air discharged by the first heat dissipation fan 14 is divided into two parts by the Y-shaped three-way pipe, one part of the hot air is returned to the cabinet 10 through the first branch pipe and the return pipe 24, and the other part of the hot air is discharged through the second branch pipe.

[0040] As shown in Figure 2 and Figure 3 , the cabinet 10 is provided with a plurality of first heat dissipation fans 14, in order to collect the hot air discharged by each first heat dissipation fan 14, the exhaust end of each first heat dissipation fan 14 is provided with a flow collector, the flow collector is used to concentrate the exhaust of each first heat dissipation fan 14, and the main pipe is connected with the exhaust end of each first heat dissipation fan 14 through the flow collector. Among them, one end of the flow collector is wide, which can cover the exhaust end of each first heat dissipation fan 14, and the other end of the flow collector is narrow, which connects the main pipe of the Y-shaped three-way pipe. Therefore, through the flow collector, the hot air of each first heat dissipation fan 14 can be introduced into the Y-shaped three-way pipe.

[0041] In an embodiment, a valve is arranged in the return pipe 24 or the first branch pipe, which is used to control the return amount of the hot air discharged by the first heat dissipation fan 14. The opening angle of the valve can be controlled, when the environment is dry, the valve can be completely closed, so that all the hot air discharged by the first heat dissipation fan 14 is discharged outside the cabinet 10. When the environment humidity is large, the valve can be controlled to be completely opened or opened at a certain angle, so that all or part of the hot air discharged by the first heat dissipation fan 14 is cooled and then returned to the cabinet 10 through the return pipe 24 for recycling.

[0042] In the above embodiment, the metal heat conduction pipe 25 is a copper pipe or an aluminum alloy pipe. In this embodiment, there is only air in the metal heat conduction pipe 25, and there is no other heat conduction medium, and the heat of the first heat dissipation fin 21 is completely transmitted to the second heat dissipation fin 22 by the metal heat conduction pipe 25. As shown in Figure 4 In an embodiment, in order to improve the heat conduction efficiency of the first heat dissipation fin 21 and the second heat dissipation fin 22, a plurality of metal heat conduction pipes 25 are connected between the first heat dissipation fin 21 and the second heat dissipation fin 22. In other embodiments, in order to improve the heat conduction efficiency of the first heat dissipation fin 21 and the second heat dissipation fin 22, the metal heat conduction pipe 25 forms a circulating closed circuit, and water or other heat conduction medium circulates in the metal heat conduction pipe 25.
