Cooling device for pump body of rotor pump

The utility model belongs to the technical field of rotor pumps, and particularly relates to a rotor pump body heat dissipation device which comprises a heat dissipation device body. A plurality of groups of liquid storage tanks are arranged at the top of the heat dissipation device body in a communicating manner; multiple sets of fourth storage grooves are formed in the two side walls of the inner side of the heat dissipation device body. First rotating columns are rotationally connected to the inner sides of the multiple sets of fourth storage grooves. A first storage groove is formed in the side wall of one side of the fourth storage groove; during working, multiple sets of reset springs enable a sealing column to reset, the side wall of the sealing column seals the outer side wall of a first rotating column, and the situation that cooling liquid on the inner side of the heat dissipation device body is discharged outwards through the space between the first rotating column and a fourth storage groove, and
