Abstract
A novel motor cooling system is composed of a fan, a heat dissipation rib, flow channels and air baffles. The fan serves as a power source, internal gas of a motor serves as heat transfer media and circulates inside the motor for cold and hot exchange, internal heat of the motor is directly carried away, and the flow channels are formed in the lower portion of the heat dissipation rib of the motor and used for cooling the internal gas of the motor, so that the gas enters a cavity of the motor again after being cooled.
Description
Art
The present invention relates to a kind of New-type electric machine cooling system, the temperature of motor stator teeth portion and rotor appearance can be effectively reduced, thus improve the useful life of motor.
Background technology
At present, the mode that the cooling of conventional motors is mainly dispelled the heat by stator back is carried out, thermal source due to motor is winding, and winding distance stator back is apart from remote, there is again the thermal insulation of insulation to affect simultaneously, making back radiating efficiency generally on the low side, for meeting the instructions for use of motor itself, heat radiation needs to increase extra power consumption and exports, and makes up the impact that radiating efficiency caused temperature rise on the low side is too high.
Summary of the invention
In order to improve the radiating efficiency of motor, the invention provides a kind of New-type electric machine cooling system: this system is made up of blower fan, radiating ribs, runner, deep bead, cooling system by blower fan as power source, using motor internal gas as heat transfer medium, make it circulate at motor internal, carry out cold and hot exchange, motor internal heat is directly taken out of, arrange runner in motor radiating muscle bottom, cool motor internal gas, after cooling, gas enters machine cavity again; The heat transfer medium of this system is the gas of motor internal, with external environment; This Operation system setting has deep bead, improves the exchange efficiency of heat in inside; In this system, have two kinds of heat exchange mediums, in two media, wherein one is gaseous state, and another is liquid; In this system, the disposed outside runner of motor radiating muscle, improves heat exchange efficiency; In this system, runner is set to through-type runner, spiral flow channel, S shape runner three kinds of forms; In this system, stators and rotators opens air holes, increase heat exchange area.
The present invention has heat exchange efficiency high feature, can effectively solve motor in real work, the situation that heat exchange efficiency is too low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1, Fig. 2, Fig. 3 are the another kind of structure charts of invention.
In figure, sequence 1 is blower fan sequence 2 for radiating ribs sequence 3 is runner
Sequence 4 is deep bead sequence 5 for stator sequence 6 is rotor
Embodiment
In FIG, motor internal gas realizes gas interior circulation by blower fan, and after blower fan, hot inside air passes through sequence 2 radiating ribs by transfer of heat to sequence 3 runner, and in runner, medium takes heat out of motor.Hot-air is by after sequence 2 radiating ribs, temperature reduces, cavity is entered by sequence 4 deep bead, again through winding surface and sequence 5 stator, gap between sequence 6 rotor, sequence 5 stator teeth heat and sequence 6 rotor surface heat are taken away by the mode of heat exchange, refrigerating gas becomes hot gas after absorbing heat again, by blower fan, again circulate.With sequential 6 stator, by itself heat transfer, partial heat is passed to sequence 3 runner, take heat out of motor by sequence 3 runner.
