[0027] Please refer to Figs. 1 to 4 It shows the specific structure of the preferred embodiment of the utility model, and it is a small base station radiating case.

The first heat dissipation fin 20, the second heat dissipation fin 21, the third heat dissipation fin 22 and the fourth heat dissipation fin 23 form air flow channels between each other, which are bottom curved and top vertical. The heat conduction seat 12 is arranged at the middle and lower part of the bottom wall of the mounting cavity, so that the heat is dissipated through the air flow in the air flow channel, and the gas in the air flow channel is accelerated due to expansion, which helps to improve the efficiency of heat dissipation.

[0029] The application provides a small base station heat dissipation cabinet, which comprises a cabinet main body 10, a sealing ring 11, a first cover plate 13, a first heat dissipation fin 20, a second heat dissipation fin 21, a third heat dissipation fin 22, a fourth heat dissipation fin 23 and a second cover plate 24. The cabinet main body 10 is internally provided with a mounting cavity. The first cover plate 13 covers the cabinet main body 10 and seals the mounting cavity. The middle and lower part of the bottom wall of the mounting cavity is provided with a plurality of heat conduction seats 12. The first heat dissipation fin 20, the second heat dissipation fin 21, the third heat dissipation fin 22 and the fourth heat dissipation fin 23 are arranged on the back of the cabinet main body 10, and the second cover plate 24 covers the first heat dissipation fin 20, the second heat dissipation fin 21, the third heat dissipation fin 22 and the fourth heat dissipation fin 23. The lower side of the first heat dissipation fin 20 is the second heat dissipation fin 21 and the third heat dissipation fin 22, and the lower side of the second heat dissipation fin 21 is the fourth heat dissipation fin 23. The structure of the second heat dissipation fin 21 is arc-shaped, and the third heat dissipation fin 22 and the fourth heat dissipation fin 23 are arranged in an inclined manner. The heat conduction seat 12 is used to contact with a heat source (such as a CPU, a heat spreading plate, a heat conduction copper plate and the like), and heat is transferred to the cabinet main body 10, and then dissipated through the first heat dissipation fin 20, the second heat dissipation fin 21, the third heat dissipation fin 22 and the fourth heat dissipation fin 23. In the embodiment, the first heat dissipation fin 20 forms a first air flow channel. The second heat dissipation fin 21 can play a role of flow guide, and directly forms a second air flow channel.

Part of the first air flow channel is connected with the second air flow channel and the fourth air flow channel, and part of the first air flow channel is connected with the third air flow channel. The heat conduction seat 12 is arranged at the middle and lower part of the bottom wall of the mounting cavity, so that the air in the second air flow channel, the third air flow channel and the fourth air flow channel is expanded by heat, and the air rises at a high speed. This design helps to improve the flow speed of the gas and the efficiency of heat dissipation. Meanwhile, the third air flow channel and the fourth air flow channel are inclined, which can accommodate more air to enter and further improve the heat dissipation capacity. The heat conduction seat 12 is a convex table structure, and is coated with heat conduction silica gel, so as to improve the heat exchange efficiency.

[0034] Preferably, the inner walls of the installation cavity and the first cover plate 13 are provided with heat-conducting copper mesh 15 or graphene paper, which helps to improve the heat conduction performance of the inside of the installation cavity and enables the heat inside to be more efficiently transmitted to the cabinet body 10 and the first cover plate 13, thereby improving the overall heat dissipation capacity.

[0035] Preferably, the outer side of the first cover plate 13 is provided with a heat dissipation groove 14. The heat dissipation groove 14 is processed by CNC, which further improves the heat dissipation capacity of the cabinet.

[0037] Preferably, the case body 10, the first cover plate 13 and the second cover plate 24 are formed by pressure forming of an aluminum alloy or a copper alloy.

[0038] In summary, the design focus of the utility model lies in that the heat-conducting seat 12 absorbs the heat of the heat source, and when dissipating heat, air will be heated and then move upward from bottom to top. The lower side of the first heat-dissipating fin 20 is the second heat-dissipating fin 21 and the third heat-dissipating fin 22, and the lower side of the second heat-dissipating fin 21 is the fourth heat-dissipating fin 23. The structure of the second heat-dissipating fin 21 is arc-shaped, and the third heat-dissipating fin 22 and the fourth heat-dissipating fin 23 are arranged in an inclined manner.
