Description
Technical field
The invention belongs to field of motor manufacturing, relate to the two cooling circuit structures of a kind of water-cooled machine shell, be particularly useful for the production of special motor cooled enclosure.
Background technology
Existing water-cooled machine is generally by arranging the S type or spiral water route structure is cooled off motor in casing, the cooling effect of motor stator part is better like this, and rotor portion is because the motor internal air is not mobile, thermal resistance is very big, heat is difficult to take away to cooling water by air transmitted, therefore will to exceed stator temperature rise many for rotor temperature rise, and having limited the motor load ability increases.General water-cooled machine shell cooling structure is to have only single water-cooled cooling structure in the motor casing, the stator heat directly conducts to cooling water by the water cooling labyrinth inwall to be taken away, obtain better cooling effect, but because the interior air of motor this moment substantially flows, the air thermal resistance is very big, the rotor heat is difficult to give the water cooling labyrinth structure division by air transmitted, has limited the load capacity of motor.
Summary of the invention
Problem to be solved by this invention is, overcome the deficiencies in the prior art, provide a kind of water-cooled machine shell two cooling circuit structures, employing arranges air-cooled in motor case and the two cooling circuits of water-cooled, make the motor internal air flow, the rotor heat flows by air and is transmitted to the water-cooling structure part, is taken away by the cooling water of water-cooled cooling circuit, improve the heat radiation cooling capacity of motor, increased the load capacity of motor.
The present invention solves its technical problem and takes following technical scheme to realize:
According to the two cooling circuit structures of a kind of water-cooled machine shell provided by the invention, comprise the stator and the rotor that are equipped with in casing and the casing, described casing internal layer is provided with the water-cooled cooling circuit, constituted by water cooling labyrinth outer wall, water cooling labyrinth inwall and reinforcement two, the inboard of water cooling labyrinth outer wall is provided with the water cooling labyrinth inwall, be provided with bosh between water cooling labyrinth outer wall and the water cooling labyrinth inwall, bosh is connected with water nozzle; The casing skin is provided with air-cooled cooling circuit, constituted by water cooling labyrinth outer wall, casing outer wall and reinforcement one, the outside of water cooling labyrinth outer wall is provided with the casing outer wall, is the cantilever ventilation hole that is formed by aluminium alloy extruded between casing outer wall and the water cooling labyrinth outer wall, and an end of rotor is equipped with fan.
The present invention compared with prior art has significant advantage and beneficial effect:
In electric machine casing, arrange air-cooled and the two cooling circuits of water-cooled because the present invention adopts, make motor internal form the wind path circulation, inner air flows, reduce motor internal air thermal resistance, the rotor heat flows by air and is transmitted to the water-cooled cooling circuit, is taken away by the cooling water of water-cooled cooling circuit, improved the heat transfer efficiency of rotor, the case material of motor is extruding aluminium alloy simultaneously, effectively raises radiating efficiency, has improved motor performance.
