Abstract

The utility model discloses a closed type switch cabinet capable of heat radiation, which comprises a cabinet body and heating elements arranged inside the cabinet body. Heat radiation devices are arranged inside the cabinet body. One end of each heat radiation device is connected with one corresponding heating element while the other end sticks out of the cabinet body. Each heat radiation device comprises heat absorption parts and heat radiation parts which are mutually connected. Each heat absorption part comprises a heat absorption clamp and a heat conduction pipe. There are at least two heat absorption parts. The heat radiation parts are arranged outside the cabinet body. Each heat radiation part comprises a base plate and radiating fins. Heat generated inside the switch cabinet can be absorbed by the heat absorption parts, then transmitted to the heat radiation parts through the heat conduction pipes and finally diffused through the heat radiation parts. Great heat radiation performances are achieved. Great sealing effects are also achieved. Dust, water, steam, etc. can be prevented from entering the switch cabinet and affecting the operation of the switch cabinet. The service lifetime of the switch cabinet can be greatly prolonged.
