The invention discloses a power battery heat dissipation system and an automobile, the power battery heat dissipation system comprises a mounting frame, a water cooling unit, an air outlet grating and an air protection cover, the water cooling unit is arranged in the mounting frame and is used for cooling a power battery, the air outlet grating is fixed on the mounting frame and is arranged corresponding to the air outlet end of the water cooling unit, and the air protection cover is fixed on the mounting frame. One end of the fan guard is connected with the air outlet end of the water chilling unit, and the other end is connected with the air outlet grille; according to the heat dissipation system, the air protection cover is arranged between the air outlet end of the water cooling unit and the air outlet grid, so that air blown out of the water cooling unit can be gathered in the air protection cover to be discharged, the air pressure blown to the air outlet grid is increased, the air outlet efficiency is improved, and therefore the heat exchange capacity of the water cooling unit is improved; and the air outlet end of the water-cooling unit is separated from the mounting frame by the air protection cover, so that the high-temperature fault of the water-cooling unit caused by hot air backflow is avoided.

    本发明公开了一种动力电池散热系统和汽车,该动力电池散热系统包括安装框架、水冷机组、出风格栅和护风罩,水冷机组设置于安装框架内,用于冷却动力电池,出风格栅固定于安装框架上,与水冷机组的出风端对应设置,护风罩的一端与水冷机组的出风端连接,另一端与出风格栅连接;该散热系统通过在水冷机组的出风端与出风格栅之间设置护风罩,使水冷机组的吹出的风能够聚集在护风罩中排出,增大了吹向出风格栅的风压,提高出风效率,从而增加水冷机组的换热能力,且护风罩使水冷机组的出风端与安装框架隔开,避免了水冷机组因热风回流而出现高温故障。
