Technical Field

[0001] The utility model belongs to the field of motors and relates to a water pump motor, in particular to a heat dissipation type water pump motor. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Water pump motors can be widely used in different fields. They are mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquids, gas mixtures and liquids containing suspended solids.

[0003] Currently, most water pump motors generate a large amount of heat when running for a long time, causing the temperature of the pump room to rise. In this case, if the water pump motor uses the hot air in the pump room to dissipate heat, it will make it difficult for the heat to dissipate, affecting the operation of the water pump motor. Although water pump motors can be cooled by water, since the water pipes in the pump room are mostly large-diameter pipes, connecting them to external water pipes may cause water hammer in the pipes, so water cooling is not convenient.
