Abstract

The invention relates to a power battery water-cooling box for an electric vehicle, relates to the field of power battery cooling, and aims at solving the problems that a power battery box is high and uneven in temperature, and meanwhile, a traditional cooling method is poor in effect. The power battery water-cooling box for the electric vehicle comprises a box body and a cooling liquid pipeline; the cooling liquid pipeline is laid in a rectangular bottom plate of the box body; a water inlet and a water outlet of the cooling liquid pipeline extend outwards through the side wall of the box body; an upper groove is arranged in an area, in which no cooling liquid pipeline is laid, on the bottom plate of the box body; a plurality of vertical ribs are arranged in the upper groove; and the upper surfaces of the vertical ribs do not exceed the upper surface of the bottom plate of the box body. The power battery water-cooling box is suitable for cooling a power battery.

Description

technical field [0001] The invention relates to the field of power battery cooling. Background technique [0002] As the core component of electric vehicles, the power battery directly affects the performance of the whole vehicle. The installation space reserved for the power battery box in the vehicle structure of electric vehicles is limited. However, in order to make the vehicle have greater power, in the design of the power battery pack, it is necessary to arrange as much power as possible in the limited space. It has become the most basic requirement for the power battery of the whole vehicle, so the power battery box will inevitably present a state where the battery modules are tightly arranged, and this arrangement leads to the middle of the module arrangement in the power battery box There is a lot of heat accumulation in the area and it is not easy to dissipate heat. The module temperature in the edge area is relatively low, which increases the temperature imbalanc...
