When the shell 1 is disassembled, the first lantern ring 6 and the second lantern ring 10 are connected in the liquid inlet ring 17, and can be automatically separated from the shell 1, so that the whole cooling system and the motor are separated, and the maintenance of parts inside the motor is facilitated.
The working principle of the application is as follows:
when in use, the first lantern ring 6 is in direct contact with the outer ring of the bearing 9, so that on one hand, heat of the bearing 9 can be absorbed, heat of the bearing 9 can be dissipated (the heat of the first lantern ring 6 is discharged through the cooling liquid of the first channel 7), and on the other hand, the bearing 9 and the rotating shaft 4 can be limited. The second collar 10 can radiate heat from the interior of the housing 1, and the heat radiation principle is as follows: the heat conducting fin conducts heat inside the housing 1 to the second collar 10, and the coolant in the second channel 11 takes away heat on the second collar 10. The heat conducting fin can adopt a copper sheet, so that heat transfer is facilitated.
