Document Type and Number:
WIPO Patent Application WO/2023/071035
Kind Code:
A1
Abstract:
A dual-flow-channel heat dissipation water pump, comprising a pump body (1), wherein the pump body (1) comprises a pump body shell (11), the pump body shell (11) is internally provided with a stator (2) and a rotor (3), an outer flow channel (9) is formed between the pump body shell (11) and a shell of the stator (2), an inner flow channel (10) is formed between the shell of the stator (2) and the rotor (3), a first outlet (60) in communication with the outer flow channel (9) is formed in an outer side of a flow guide housing, a second outlet (61) in communication with the inner flow channel (10) is formed in one side of the flow guide housing facing a front cover of the stator (2), and fluid flows out from the first outlet (60) or the second outlet (61) to perform heat dissipation on the stator (2) and the rotor (3) at the same time. The water pump performs heat dissipation on an electric motor by means of the working fluid without being additionally provided with a heat dissipation structure.
