The interior of the partition assembly 20 is a hollow structure and encloses a main equipment area 43. A return air passage 40 is enclosed between the top of the partition assembly 20 and the cabinet body 10. The main equipment area 43 enclosed by the partition assembly 20 divides the cabinet body 10 into a cold air area 41 and a hot air area 42. The outdoor communication cabinet 100 provided by the utility model can divide the cabinet into the cold air area 41, the main equipment area 43 and the hot air area 42 by using the partition assembly 20 to enclose the main equipment area 43 and divide the cabinet body 10 into the cold air area 41 and the hot air area 42. Thus, the gas flow in the cabinet body 10 can be effectively organized and managed, and the cold air area 41 and the hot air area 42 are strictly distinguished. Therefore, the hot air formed by the cold air generated in the heat exchanger 30 flowing through the main equipment area 43 can be effectively blown out of the cabinet body 10 through the hot air area 42. Thus, the mixing and crossing of the cold and hot air in the cabinet body 10 can be effectively avoided, and the heat exchange efficiency of the outdoor communication cabinet 100 is effectively improved. In addition, the return air passage 40 enclosed between the top of the partition assembly 20 and the cabinet body 10 can effectively prevent the hot air formed by the cold air generated in the heat exchanger 30 flowing through the main equipment area 43 from flowing back to the main equipment area 43. Thus, the equipment in the main equipment area 43 can continuously exchange heat with the cold air generated in the heat exchanger 30, and the heat exchange efficiency of the outdoor communication cabinet 100 is further improved.

[0025] As Figure 1As shown, in the embodiment provided by this utility model, the partition assembly 20 includes a left partition 21, a right partition 22, and a middle partition 23 disposed on top of the left partition 21 and the right partition 22. The left partition 21, the right partition 22, and the middle partition 23 enclose a main equipment area 43. The middle partition 23 and the cabinet 10 enclose a return air channel 40. By installing equipment with higher heat generation power in the main equipment area 43 and utilizing the return air channel 40 formed by the middle partition 23 and the cabinet 10, the hot air generated after the cold air generated in the heat exchanger 30 flows through the main equipment area 43 can be effectively prevented from flowing back into the main equipment area 43, ensuring that the equipment in the main equipment area 43 continuously exchanges heat with the cold air generated in the heat exchanger 30, thereby further improving the heat exchange efficiency of the outdoor communication cabinet 100.

The air in the external environment enters the heat exchanger 30 through the outer circulation air inlet 32, exchanges heat with the cold heat exchange medium 31, and then flows to the main equipment area 43 through the inner circulation air outlet 35, and then exchanges heat with the cold air entering the main equipment area 43 by using the air outlet or fan of the equipment in the main equipment area 43, and the hot air formed flows into the hot air area 42, and then flows into the heat exchanger 30 through the inner circulation return air outlet 34 and is blown out of the cabinet 10 through the outer circulation air outlet 33. By setting the inner circulation return air outlet 34 close to the outer circulation air outlet 33 and the inner circulation air outlet 35 close to the outer circulation air inlet 32, the air entering the heat exchanger 30 through the outer circulation air inlet 32 can be exchanged by the cold heat exchange medium 31 and form cold air, and then blown to the main equipment area 43 through the inner circulation air outlet 35 in time, and the hot air flowing through the main equipment area 43 flows through the return air passage 40 and enters the heat exchanger 30 through the inner circulation return air outlet 34 in time, and then is blown out of the cabinet 10 through the outer circulation air outlet 33, thereby effectively ensuring that the hot air flowing through the return air passage 40 is blown out of the cabinet 10 in time, thereby further improving the heat exchange efficiency of the outdoor communication cabinet 100, avoiding the hot air flowing back to the cold heat exchange medium 31, and affecting the heat exchange effect of the cold heat exchange medium 31. In addition, a plurality of second fans 341 are arranged at the inner circulation return air outlet 34, which can effectively improve the efficiency of the hot air in the hot air area 42 being sucked into the cold heat exchange medium 31 in the heat exchanger 30, thereby further improving the heat exchange efficiency of the outdoor communication cabinet 100, avoiding the hot air flowing back to the cold heat exchange medium 31, and affecting the heat exchange effect of the cold heat exchange medium 31.

[0028] As Figure 3As shown in the embodiment provided by the utility model, the cold air region 41 is formed between the cold heat exchange medium 31 and the right partition plate 22, the hot air region 42 is formed between the left partition plate 21 and the cabinet 10 and the return air channel 40, so that the cabinet is divided into the cold air region 41, the main equipment region 43 and the hot air region 42, and the gas flow in the cabinet 10 is effectively organized and managed, the cold air region 41 and the hot air region 42 are strictly distinguished, the hot air formed after the cold air generated in the heat exchanger 30 flows through the main equipment region 43 is blown out of the cabinet 10 through the hot air region 42, the cold and hot air in the cabinet 10 is prevented from mixing and crossing, and the heat exchange efficiency of the outdoor communication cabinet 100 is effectively improved.

[0029] In addition, as Figure 1 As shown, the left partition plate 21 and the right partition plate 22 are provided with a plurality of wire outlet holes 50, the wiring requirement of the equipment in the cabinet 10 can be effectively met through the plurality of wire outlet holes 50 on the left partition plate 21 and the right partition plate 22, and the air-tight protection effect is realized, the air tightness is guaranteed, the wiring requirement in the cabinet is met, the air tightness is guaranteed, the isolation effect of the cold air region 41 and the hot air region 42 in the cabinet 10 is further improved, when the equipment in the main equipment region 43 is not fully configured, the cold air can flow to the equipment in the main equipment region 43 through the installation of the false panel, the cold air must pass through the main equipment channel to reach the hot air region 42, the cold air region 41 and the hot air region 42 are prevented from directly mixing and conducting, and the situation that the heat dissipation efficiency of the cabinet is low is avoided.
