The utility model provides a cooling device of battery modules of an electric car. The cooling device comprises battery modules, heat conducting devices and air cooling devices, wherein each battery module comprises a plurality of battery cells arranged in parallel; the heat conducting devices are arranged at the sides of the battery modules and are used for conducting the heat emitted from the interior of battery packs out of the battery packs; the air cooling devices are arranged at one sides of the battery modules and are used for taking away the heat on the heat conducting devices with strong wind. Compared with traditional battery module cooling modes, the cooling device provided by the utility model has the beneficial effects that heat pipes are inserted between the battery cells and penetrate into the battery packs, so that the cooling device has the advantage of uniform temperature distribution; the heat conducted by the heat pipes is taken away by fans, thus improving the heat conducting efficiency.
