Heat dissipation device in electrical cabinet

Abstract

The invention relates to a heat dissipation device in an electrical cabinet. The heat dissipation device comprises a fixing pipe, a connecting pipe, a heat dissipation ball, and a gas circulation pipeline. The top end of the fixing pipe is fixedly connected with the top plate in the electrical cabinet, and a clapboard is disposed in the connecting pipe. The bottom plate of the bottom part of the connecting pipe is uniformly provided with air vent holes, and the heat dissipation ball comprises 3-20 arc-shaped heat dissipation pipes. The heat dissipation pipes are provided with heat dissipation holes, and the bottom parts of the heat dissipation pipes in the heat dissipation ball are merged together. The gas circulation pipeline comprises an air exhaust pipe, an air pump, and an air feeding pipe. The connecting pipe is provided with a connecting pipe adjusting device, which comprises a cabinet fixing plate, a first connecting rod, a second connecting rod, a third connecting rod, and a spring. The heat dissipation device has advantages of good heat dissipation effect, simple and flexible structure.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a heat dissipation device in an electric cabinet. Background technique [0002] The electrical cabinet is made of steel and used to protect the normal operation of components. With the advancement of technology, more and more electronic devices are installed in the electrical cabinet, and the heat generated is also increasing. This makes the heat dissipation The motor of the fan needs to work with high load for a long time, and the motor itself will generate a lot of heat when it is working. Working at a high temperature will affect the life and reliability of the motor. Once the motor is damaged or fails, it will affect the electrical cabinet. Devices, these devices may be damaged due to high temperature, causing electricity accidents and posing safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat...
