In this process, the low-temperature air will absorb the heat inside the electrical cabinet. The fan 35 can be purchased directly from the market. The fan 35 provides power for the entry of cold air and the discharge of hot air. Part of the branch pipe 33 is retractable to facilitate the movement of the frame 22.

[0037] Before the use of the utility model, firstly, the distance between the air duct 26 on the frame 22 and the electronic components on the mounting frame 21 is adjusted by the telescopic rod 82. After the adjustment is completed, the longitudinal beam 24 is rotated. The rotation of the longitudinal beam 24 changes the direction of the air outlet 27 on the air duct 26, so that the cold wind can be blown to different positions on the mounting frame 21 through the air outlet 27. After the position of the air outlet 27 is adjusted, when the electrical cabinet is used, the fan 35 is started, and the low-temperature air near the air inlet 31 will be sucked into the air collecting pipe 32 to form cold wind, and then the cold wind enters the air duct 25 inside the two longitudinal beams 24 respectively through the two branch pipes 33, and then enters the air duct 26 again and is blown out from the air outlet 27. Then the cold wind circulates inside the electrical cabinet and is finally discharged from the air outlet 34. In the process of the cold wind circulating inside the electrical cabinet, it will drive the heat dissipated from the electronic components on the mounting frame 21, thereby achieving the effect of cooling the electrical cabinet.
