The heat radiator 3 is arranged on the pump shaft 2 between the pump body 1 and the bearing 5, heat in the pump body 1 is transmitted to the bearing 5 through two paths of the pump shaft 2 and the bearing body 4, the heat radiator 3 conducts forced heat dissipation when rotating along with the pump shaft 2, and heat transmitted through the pump shaft can be separated. The radiating fins 8 are uniformly arranged on the outer circumference of the bearing body 4, and the radiating fins 8 increase the heat exchange area and contribute to enhancing the cooling effect. The fan 6 is arranged on the side of the bearing body 4 far away from the radiator 3, and the fan 6 can forcibly cool the bearing body 4 during rotation.
Referring to fig. 2, the heat sink 8 is composed of a set of metal disks, and the heat sink 8 can absorb heat transferred from the pump shaft 2 in contact with the heat sink, so that the heat absorbed by each metal disk can be dissipated in time, and a certain gap is formed between the metal disks. And, in order to facilitate the mounting and dismounting, each disc is threadedly coupled to the pump shaft 2. Of course, as another specific embodiment, each metal disk may be mounted on the pump shaft in an interference fit manner in order to make the connection between each metal disk and the pump shaft 2 more firm.
As an embodiment of the present invention, referring to fig. 3, the heat dissipating fins 8 are integrally molded with the bearing body 4, the heat dissipating fins 8 are uniformly fixed on the circumference of the bearing body 4 in the axial direction, and each heat dissipating fin 8 extends radially outward by a distance of one end.
