A mounting cabinet for rail transit bidirectional converters capable of multi-stage heat dissipation

Abstract

The invention discloses a multi-stage heat dissipation installation cabinet for a rail transit bidirectional converter, and relates to the technical field of heat dissipation for bidirectional converters. The invention comprises a cabinet body, one side wall of the cooling water circulation chamber is fixedly connected with a first hollow fin, the other side wall of the cooling water circulation chamber is fixedly connected with a second hollow fin, and the water inlet end of the water pump is connected with the inside of the cooling water storage chamber through a water pipe. The outlet end of the water pump communicates with the interior of the cooling water circulation chamber through a water pipe, and the bottom of the cooling water circulation chamber communicates with the interior of the cooling water storage chamber through a return pipe. In the present invention, through the design of the cooling water circulation chamber, the first hollow fin, the second hollow fin, the water pump, the return pipe and the fan, combined with water cooling and air cooling, the heat generated inside the installation cabinet is dissipated in multiple stages, improving the The heat dissipation efficiency avoids the problem that the heat generated inside the installation cabinet of the existing bidirectional converter is difficult to discharge, which affects the service life of the instrument, and even directly causes damage to the instrument.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation of bidirectional converters, in particular to a multi-stage heat dissipation installation cabinet for rail transit bidirectional converters. Background technique [0002] Compared with other modes of transportation, urban rail transit has the characteristics of safety, comfort, speed, large capacity, energy saving and environmental protection. However, with the expansion of road network scale and the sharp increase of passenger traffic, the total energy consumption of urban rail transit has also increased significantly, and the serious problem of train braking energy waste has been increasingly concerned. In order to solve the absorption and utilization of locomotive braking electric energy, bidirectional bidirectional converters have become the direction of technological development because of their rectification and inverter functions. [0003] A large number of connectors and various ...
