The invention provides a heat dissipation device and a heat dissipation method of a vehicle-mounted liquid cooling system. The heat dissipation device comprises a liquid tank (2), a top cover (1) covering the upper surface of the liquid tank, and an air bellow located below the liquid tank. The liquid tank is used for communicating with a circulation pipeline of cooling liquid, the top cover and the upper surface of the liquid tank jointly define a running air channel for running air of a vehicle to pass through, a plurality of parallel first heat dissipation plates connected with the upper surface of the liquid tank are arranged in the running air channel, and the first heat dissipation plates are arranged in the extending direction of the running air channel. A plurality of parallel second heat dissipation plates connected with the lower surface of the liquid tank are arranged in the air bellow, the second heat dissipation plates are arranged in the direction perpendicular to the first heat dissipation plates, the air inlet of the air bellow is located in the bottom face, the air outlet of the air bellow is located in the side face corresponding to the ends of the second heat dissipation plates, and a draught fan (3) is arranged at the air outlet. By adopting the heat dissipation device provided by the invention, the degree of dependence on the heat dissipation fan can be reduced, the energy consumption can be reduced, and the excessive noise of the fan can be avoided.
本发明提供了一种车载液冷系统的散热装置和散热方法,该散热装置包括液箱(2)、罩于液箱的上表面的顶盖(1),以及位于液箱下方的风箱。液箱用于与冷却液的循环管路相连通,顶盖与液箱的上表面共同围成供车辆的走行风通过的走行风通道,走行风通道内设置有与液箱的上表面连接的多个相互平行的第一散热板,第一散热板沿走行风通道的延伸方向布置。风箱内设置有与液箱的下表面连接的多个相互平行的第二散热板,第二散热板沿垂直于第一散热板的方向布置,风箱的进风口位于底面,出风口位于与第二散热板的端部相对应的侧面,出风口处设置有风机(3)。采用本发明提供的散热装置,可降低对散热风机的依赖程度,有助于减小能耗及避免风机噪声过大。
