Cooling device for supercharger

The utility model discloses a cooling device for a supercharger. The cooling device comprises an upper positioning block, a pump body is arranged on one side of the upper positioning block; a water guide pipe is arranged on one side of the upper positioning block, and a lower positioning block is arranged on one side of the water guide pipe; wherein a heat dissipation hole is formed in one side of the lower positioning block, a water storage tank is arranged on one side of the heat dissipation hole, water in the water storage tank is guided into the cooling pipe through the pump body, so that the water conveniently flows through the surface of the supercharger, heat generated by the supercharger is taken away, and the heat dissipation pipe and the heat dissipation hole are arranged, so that the heat dissipation efficiency is improved. Water absorbing heat can be in contact with air entering from the heat dissipation holes conveniently and rapidly in the falling process, the purpose of water heat dissipation i
