Compared with the prior art, the utility model has the following beneficial effects:
(1) by the way that the heat exchange water channel is arranged on the casing ontology 1, so that the cooling in the heat exchange water channel
Liquid absorbs and takes away the heat of motor generation, to realize the radiating and cooling of motor, and then is conducive to the normal operation of motor.Tool
Body, in motor operation, the lower coolant liquid of temperature is transported in the heat exchange water channel by external water inlet pipe, and coolant liquid exists
It migration and exchanges heat with the lateral wall of the casing ontology 1 in the heat exchange water channel, to absorb the heat of motor generation simultaneously
As the higher coolant liquid of temperature, so that it is excessively high to be effectively prevented from motor temperature；The higher coolant liquid of end temperature flows out to outer
Portion's outlet pipe, to take away the heat of motor generation, coolant liquid so circulated, the heat that can effectively generate motor and
When be effectively dissipated away.
(2) the water channel sealing shroud 6 and the casing ontology 1 interference fit or clearance fit, to seal the heat exchange
Water channel, the coolant liquid so as to be effectively prevented from the heat exchange water channel are revealed, and will without welding procedure
Gap between the casing ontology 1 and the water channel sealing shroud 6 carries out weld seam, thus assembling the water cooling motor housing sealing
When structure, directly the water channel sealing shroud 6 is set on the casing ontology 1, and then extracts the water in disassembly
Road sealing shroud 6；In this way, the water cooling motor housing sealing structure not only assembles simple, convenient disassembly, and save manually at
This, is conducive to the maintenance of equipment.
(3) when the water channel sealing shroud 6 is with the casing ontology 1 interference fit or clearance fit, two sealings
The sealing 18 of device 17 is sealedly connected on the inner sidewall of the water channel sealing shroud 6, thus by the water channel sealing shroud 6 and institute
The gap stated between casing ontology 1 is sealed；Wherein, the sealing 18 is using leakproofness such as silicon rubber, fluorine silicone rubber, resistance to
Hot good material, and there is stronger anti-compression property, it can will be between the water channel sealing shroud 6 and the casing ontology 1
Clearance gap simultaneous adaptation described in hydraulic pressure in heat exchange water channel, to be effectively guaranteed the water cooling motor housing sealing structure
Water channel leakproofness, and assemble simple, without expending higher cost of labor, and then advantageously reduce the production cost of motor.
(4) sealing ring is using good materials of leakproofness, heat resistance such as silicon rubber, fluorine silicone rubber, and has relatively strong
Anti-compression property.It should be understood that when the water channel sealing shroud 6 is with the casing ontology 1 interference fit or clearance fit, institute
The inner sidewall for stating water channel sealing shroud 6 squeezes the sealing ring, meanwhile, it is close that the sealing ring can tightly be attached to the water channel
On the inner sidewall of big envelope 6, to be effectively prevented from coolant liquid leakage；Simultaneously as the sealing ring is also structure in a ring, fit
The water channel sealing shroud 6 and the shell body assigned in cylinder-like structure, the then sealing ring on two sealing devices 17
Space sealing between the lateral wall of the casing ontology 1 and the inner sidewall of the water channel sealing shroud 6 can be lived, to guarantee
The leakproofness and reliability of the water cooling motor housing sealing structure.
(5) the water channel sealing shroud 6 of polygonized structure is conducive to increase when assembly on the water channel sealing shroud lateral wall
Impetus, to avoid skidding, and then advantageously reduce the assembly difficulty of the water cooling motor housing sealing structure.
(6) supporting element 16 is used to support the effect for the water channel sealing shroud 6 being set on the casing ontology 1, favorably
In avoiding the motor using the water cooling motor housing sealing structure from being deformed by external compression, so that it is close to improve the water channel
Big envelope 6 is set in the stability on the casing ontology 1.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the protection scope of the utility model.
