Walking air-cooling type heat exchanger

Abstract

The present invention provides a walking air-cooling type heat exchanger. The walking air-cooling type heat exchanger comprises a heat exchange assembly; the heat exchange assembly includes first heatexchangers and second heat exchangers; the first heat exchangers and the second heat exchangers are provided with air tunnels; the air tunnels of the first heat exchangers are arranged along a walking wind direction; and the air tunnels of the second heat exchangers are arranged along a vertical direction. The heat dissipation reliability of the heat exchanger is excellent with no fans provided.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a traveling air-cooled heat exchanger. Background technique [0002] In recent years, the rail transit industry has developed rapidly, and the power module has been used as a key component. In order to meet the application requirements of rail transit, the integration of the power module is getting higher and higher, and the heating power is getting bigger and bigger. The research found that the heat Failure has become its main failure mode, especially under harsh working conditions, and failures often occur. Therefore, thermal management has become a bottleneck that needs to be solved urgently in the development of electronic equipment. However, to effectively control the junction temperature of electronic components, not only a heat sink with good performance is required, but also a heat exchanger with good performance is required, because the heat is finally dissipated to the surr...

Problems solved by technology

[0003] In the field of rail transit or high-power heat dissipation, the driving force is usually provided by the running wind instead of the fan, and the driving wind exchanges heat with the heat exchanger. However, due to the size limitation, the heat exchanger is installed at the bottom of the cabinet, which seriously affects the Natural convection heat dissipation when the body is still

Specifically, when the vehicle is stationary, the auxiliary equipment (such as air conditioners, fans, water pumps, etc.) is still running. At this time, the heat loss of the heat exchanger is high. It will lead to the failure of the heat exchanger, and the auxiliary equipment will stop running due to high temperature.
