Abstract

The invention discloses a sealed electric box applied to a severe environment, and belongs to the technical field of electric device protection. The sealed electric box comprises a sealed box body module, wherein a ventilation pipeline is arranged in the sealed box body module, vent holes are formed in the ventilation pipeline, the two ends of the ventilation pipeline extend out of the sealed boxbody module to be connected with ventilation equipment, and a wiring module is arranged on the side part of the sealed box body module. The problem that an existing electrical component is short in service life in a severe environment is solved, it can be guaranteed that the electrical component is prevented from being damaged by the external severe environment, and meanwhile, the temperature in abox body is effectively reduced, the heat dissipation performance is improved, protection of the internal electronic component is better facilitated, and the selectivity is improved for arrangement of equipment electronic components and circuits.

Description

technical field [0001] The invention relates to a sealed electric box used in harsh environments, and belongs to the technical field of electric device protection. Background technique [0002] At present, due to the adverse effects of harsh environments on the performance of electronic components, electronic components are generally placed outside the harsh environment when used, but under special conditions, it is difficult to solve this problem when components are required to work inside the harsh environment ; [0003] In the prior art, the application number is CN201821101976.8, which discloses a sealed electric box resistant to high temperature, humidity, and internal pollution, including a box body and a door panel. A sealing rubber pad is arranged inside the door panel, and a door panel row hinge is arranged on one side of the outer periphery of the door panel. , the other three sides of the door panel are provided with anti-bending flanging, the outlet hole is set ...
