The invention discloses a micro-channel heat dissipation device mounted on a train, the device comprises a first air duct, a heat transfer mechanism and a second air duct, and the section of the first air duct from an inlet to an outlet is gradually reduced; the heat transfer mechanism is arranged at an outlet of the first air duct and comprises a ventilation pipe and cooling fins, the cooling fins are arranged on the periphery of the ventilation pipe, a plurality of heat exchange pipes are arranged in the ventilation pipe, and a heat-conducting medium circulates in micro-channels in the heat exchange pipes and is used for absorbing heat of heating equipment; the second air duct communicates with an outlet of the ventilation pipe; the pipe wall of the ventilation pipe communicates with an air inlet pipe, the air inlet pipe communicates with an outlet of the first air channel, and the section of the air inlet pipe is gradually reduced. According to the technical scheme, the heat dissipation device is installed on the train, air is sucked in through the first air channel, then the air flow speed is further increased through the air inlet pipe, the air rapidly flows in the ventilation pipe, the heat exchange efficiency of the air and the heat exchange pipe can be improved, and then heat generated by heating equipment of the train is discharged to the outside.
本发明公开了一种安装于列车上的微通道散热装置,装置包括第一风道、传热机构以及第二风道,第一风道的入口至出口的截面逐渐缩小;传热机构设于第一风道的出口处,传热机构包括通风管和散热片,散热片设于通风管的外周,通风管的内部设有若干个热交换管,热交换管内部的微通道循环有导热介质,用于吸收发热设备的热量;第二风道连通通风管的出口;其中,通风管的管壁连通有进风管,进风管连通第一风道的出口,进风管的截面逐渐缩小。本技术方案中,将该散热装置安装于列车上,通过第一风道吸进空气,再利用进风管进一步地提升空气流速,空气在通风管内快速流动,能够加快空气和热交换管的换热效率,进而对列车的发热设备产生的热量排出到外界。
