Abstract

The invention provides a heat radiation apparatus of a power supply cabinet power device. The heat radiation apparatus of a power supply cabinet power device includes a heat radiation air duct, a connection wind scoop and an axial-flow blower fan, wherein the cross section of the heat radiation air duct is cylindrical-frame-shaped, and the front end of the heat radiation air duct is a heat radiation outlet, and the back end of the heat radiation air duct is an air inlet; and one end of the connection wind scoop is connected with the air inlet of the heat radiation air duct in a sealed manner,and the other end of the connection wind scoop is connected with the air outlet of the axial-flow blower fan in a sealed manner. The heat radiation apparatus of a power supply cabinet power device utilizes the air extraction function of the axial-flow blower fan and the head radiation function of the air flow to realize the blower fan type head radiation of the power supply cabinet, thus greatly simplifying the structure of the heat radiation apparatus, and reducing the production cost of the heat radiation apparatus.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle ground equipment, and in particular relates to a heat dissipation device for a power device of a power supply cabinet. Background technique [0002] Most of the cooling devices of existing power devices are water-cooling technology, but the water circulation and water sealing technology in water-cooling technology are costly, prone to failure, and high maintenance costs. Technicians urgently need to study a simple structure and strong controllability. , Fan type cooling device with easy maintenance. Contents of the invention [0003] In view of this, the present invention aims to propose a cooling device for power devices in the power cabinet, which utilizes the air extraction function of the axial flow fan and the heat dissipation function of the airflow to realize the fan-type heat dissipation of the power cabinet, greatly simplify the structure of the cooling device, and reduce the heat ...
