Description
Technical field
The utility model relates to a kind of motor cooling mechanism, is specifically related to the two cooling circuit structure of a kind of water cooling motor housing, belongs to motor cooling device technical field.
Background technology
Existing water-cooled machine generally by arranging S type or spiral waterway structure cools motor in casing, the cooling effect of such motor stator portion is better, and rotor portion does not flow due to motor internal air, thermal resistance is very large, heat is difficult to be taken away to cooling water by air transmitted, therefore will to exceed stator temperature rise many for rotor temperature rise, and limiting motor load ability increases; General water cooling motor housing cooling structure only has single cooling by water structure in motor casing, stator heat is directly conducted by water cooling labyrinth inwall to be taken away to cooling water, obtain good cooling effect, but because air in now motor does not flow substantially, air thermal resistance is very large, rotor heat be difficult to by air transmitted to water cooling labyrinth structure division, limit the load capacity of motor; In order to solve the problems of the technologies described above, we have developed the two cooling circuit structure of a kind of water cooling motor housing, China application number 201310239158.X, it is specific as follows: casing internal layer is provided with cooling by water loop, be made up of water cooling labyrinth outer wall, water cooling labyrinth inwall and reinforcement two, the inner side of water cooling labyrinth outer wall is provided with water cooling labyrinth inwall, and be provided with bosh between water cooling labyrinth outer wall and water cooling labyrinth inwall, bosh is connected with water nozzle; Casing skin is provided with air-cooled cooling circuit, be made up of water cooling labyrinth outer wall, casing outer wall and reinforcement one, the outside of water cooling labyrinth outer wall is provided with casing outer wall, is that fan is equipped with in one end of rotor by aluminium alloy extruded cantilever ventilation hole between casing outer wall and water cooling labyrinth outer wall.The present invention adopts in motor case, arranges the air-cooled and two cooling circuit of water-cooled, motor internal air is flowed, and rotor heat is transmitted to water-cooling structure part by air flowing, is taken away by the cooling water in cooling by water loop, improve the cooling ability of motor, increase the load capacity of motor; But through test of many times, find that its cooling effect does not also reach perfect condition, reason is air-cooled is waiting type cooling, and itself and rotor heat transfer effect are poor.
