Abstract

The invention discloses a heat dissipation device for a rail vehicle inverter box in the technical field of the vehicle cooling device. The heat dissipation device comprises a box body. A support board is laterally mounted inside the box body; a mounting board is internally mounted in the support plate; and an inverter and a controller are installed at the top of the mounting board respectively. Acooling tube is installed at the bottom of the mounting board. Fans are installed at the two sides of the bottom of the inner cavity of the box body; and an air inlet is formed in the bottom of the box body. A drying plate I is installed above the air inlet at the bottom of the inner cavity of the box body. A box cover is hinged to one side of the top of the box body by a hinge. A temperature sensor is installed at the bottom of the box cover; air outlets are formed in the two sides of the outer wall of the box cover; and a drying plate II is installed at the top of the box cover. Under the effect of the fans and a cooling tube, heat is led out rapidly and is exchanged quickly to ensure the balance of the internal temperature of the box body; and the drying plate I and the drying plate IIdry the humid gas, thereby protecting the internal circuit from being in a short-circuit state. The heat dissipation modes are diversified; the heat dissipation efficiency is high; and the operationis simple.

Description

technical field [0001] The invention relates to the technical field of vehicle heat dissipation equipment, in particular to a heat dissipation device for a rail vehicle inverter box. Background technique [0002] The rail vehicle DC600V inverter is a modular design and is hung under the vehicle in the form of a box to provide AC380V power for three-phase loads such as air conditioners, oxygen generators, and electrical cabinets on the vehicle to ensure the normal use of the load and improve passenger comfort. However, due to the large load and high power of the inverter module, overheating and high temperature rise of the inverter after working for a long time will lead to module failure, which will affect the normal use of the refrigeration, oxygen generation and other equipment on the vehicle. [0003] At present, heat dissipation fins are mostly used as natural fans. In order to expand the heat dissipation area, longer fins are required, which takes up a lot of space unde...
