Title:
MOTOR HOUSING HAVING GOOD HEAT DISSIPATION
Document Type and Number:
WIPO Patent Application WO/2021/087940
Kind Code:
A1
Abstract:
A motor housing having good heat dissipation, comprising a motor (3) and a water pump (9). The motor (3) comprises a motor rotor (1); the motor housing having good heat dissipation further comprises a first heat dissipation body (2) and a second heat dissipation body (4); the motor (3) is electrically connected by an external power source; the inner walls of the first heat dissipation body (2) and the second heat dissipation body (4) are tightly attached to the outer wall of the housing of the motor (3); the first heat dissipation body (2) is fixedly mounted at the upper end of the second heat dissipation body (4) by screws; the first heat dissipation body (2) comprises a first water diversion pipe (7), a water diversion sealing housing (10), a heat dissipation sealing housing (11), a heat dissipation water guide pipe (12), and a second water diversion pipe (13); one end of the first water diversion pipe (7) is fixedly connected to the outer wall of the water pump (9), and the other end of the first water diversion pipe (7) is fixedly connected by the heat dissipation water guide pipe (12); an internal space of the first water diversion pipe (7) is communicated with an internal space of the water pump (9). The heat dissipation effect is enhanced by means of water-cooling circulation, and use requirements are better met.
