The main purpose of the ventilation of the cabinet 1 is for heat dissipation;

when the flow speed of the gas is suddenly increased, the internal energy can be lost, for example, the flow speed in the pipeline is suddenly increased, the gas can absorb heat energy through the pipeline and the heat energy is converted into the internal energy by a lamp, and the specific expression after the heat energy on the pipeline is lost is that the temperature is reduced;

therefore, in the technical scheme, the internal space of the cabinet body 1 is divided by the partition plate 4, so that the working interval of the electronic element and the working interval for heat dissipation do not intersect, air flow does not circulate in the upper cavity 5 and does not enter the upper cavity 5, and dust is prevented from entering;

at the same time, the air pumping device 11 forces the air to pass through the fan housing 12, the cooling pipe 9 and the air outlet pipe 10 in sequence, due to the unit flow (m) of the air outlet pipe 10 and the air pumping device 11³The flow/s) is larger than the sum of the unit flow of the plurality of cooling pipes 9, so that when the air extracting device 11 works, the unit flow of the plurality of cooling pipes 9 is not equal to the flow of the air extracting device 11, and further, the flow velocity of the gas in the cooling pipes 9 is increased, the pressure intensity is increased, and finally, the temperature of the pipe walls of the cooling pipes 9 is reduced;

the cooling pipe 9 is indirectly contacted with the mounting rack 7 through the heat absorbing plate 8, the heat dissipation of the electronic component is realized, the heat absorption capacity of the cooling pipe 9 is further utilized, the cooling pipe 9 is in clearance fit with the inner wall of the cabinet body 1, meanwhile, a cold cavity with lower temperature is actually formed between the heat absorbing plate 8 and the inner wall of the cabinet body 1, the cold and hot air exchange of the spaces on two sides of the heat absorbing plate 8 is realized through the through holes 13 on the plate wall of the heat absorbing plate 8, the self-circulation of the air inside the upper cavity 5 is formed, and the heat dissipation effect is further improved.

Specifically, the cooling pipe 9 is embedded in one side of the heat absorbing plate 8 far away from the mounting frame 7, the cooling pipe 9 is arranged at equal intervals, and the cooling pipe 9 is in clearance fit with the inner wall of the cabinet body 1.

Specifically, the air extracting device 11 includes a driving motor 18, the driving motor 18 is connected with an impeller through a transmission shaft, the impeller is located inside the fan housing 12, and both the driving motor 18 and the fan housing 12 are fixed to the bottom plate inside the cabinet 1.
