Abstract
The utility model relates to a liquid filling cooling motor. GY101 transformer silicone cooling liquid is charged into the cavity of a motor bedplate to directly carry out heat exchange with the heating component of the motor, and after the cooling liquid absorbs the heat quantity, the cooling liquid carried out heat exchange with the outer circulation cooling water which flows through a water channel which is composed of a base water chamber, an end cover channel and a cooler in series. The utility model has the advantages of raising cooling effect and enhancing above 40% of output power compared with a water-cooled machine with the same volume.
Description
The utility model belongs to water cooled machine.
Up to now, the cooling of water cooled machine is to carry out heat exchange by the cooling water that flows through in the water jacket of motor housing, reaches cooling.This kind type of cooling in enclosed motor owing to be not the heat generating components of directly cooled machine, thus the heat exchange difficulty, low, the weak effect of cooling effectiveness.The motor internal temperature gradient is big, influences the power output and the normal operation of motor.
The utility model is at above-mentioned existing problems, provides a kind of cooling fluid is directly charged into topping up cooling motor in the motor cavity, reduces electric machine temperature rise, improves cooling effect and power output.
Topping up cooling motor of the present utility model is that cooling fluid is injected enclosed motor support cavity by the liquid injection hole of electric machine stand upper end, directly with the heat generating components of motor, as: stator, rotor winding directly contact, the generation heat exchange; The heat that cooling fluid absorbs then carries out heat exchange by electric machine stand hydroecium, end cap water channel, the water cooler outer circulation cooling water that constitutes of being connected, and by cooling water heat is taken out of.
Cooling fluid is selected flame retardant type electrolyte for use, can make machine operation in the workplace with explosive atmosphere.
Symmetrical with liquid injection hole, be provided with taphole in the electric machine stand lower end, the observation window of symmetry is set on support; The cooling water import and export is interchangeable; Machine shaft and end caps adopt mechanical seal.
Remarkable result of the present utility model: under identical principal parameter, equal volume, the topping up cooling motor is compared with general water-cooled machine, and power output can improve more than 40%.For require at special occasions motor volume little, when power output is big, significant.
Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described in detail.
