The invention relates to the technical field of refrigerating systems, and discloses an auxiliary cooling device for an automobile cooling system, the auxiliary cooling device comprises a base and a heat dissipation body, a bottom plate is fixed in the base, the heat dissipation body is arranged on the bottom plate, one end of the heat dissipation body is rotatably connected to the bottom plate, and the heat dissipation body is covered with waterproof cloth. Air pressure balance holes are formed in the upper bottom face and the lower bottom face of the base respectively, a liquid inlet pipe and a liquid outlet pipe are arranged at the two ends of the bottom plate respectively, and an electric control valve is installed on the liquid inlet pipe. The heat dissipation body is pushed to be unfolded upwards through the air pressure difference between the roof and the interior of the vehicle when the vehicle runs at a high speed, the heat dissipation body can be automatically unfolded and folded along with the running speed of the vehicle through the characteristic that the vehicle speed, the coolant temperature, the air pressure difference and the stretching area of the heat dissipation body are in direct proportion, and on the premise that the cooling effect on the coolant is improved, the cooling liquid is prevented from being too cold or too hot, so that the cooling liquid is kept at the optimal temperature.

    本发明涉及制冷系统技术领域,且公开了一种汽车冷却系统用辅助降温装置,包括底座和散热体,所述底座的内部固定有底板,所述底板上设有散热体,所述散热体的一端转动连接在底板上,所述散热体上罩设有防水布,所述底座的上下底面均开设有气压平衡孔,所述底板的两端分别设有进液管和出液管,所述进液管上安装有电控阀。本发明通过利用车辆高速行驶时车顶与车内的气压差推动散热体向上展开,利用车速、冷却剂温度、气压差、散热体的伸展面积成正比的特性,使得散热体可自动随着车辆的行驶速度而伸展和折叠,在提高对冷却剂的降温效果的前提下,也防止冷却液过冷或者过热,使得冷却液保持在最佳温度。
