Description
Technical field
the present invention relates to motor cooling, be specifically related to a kind of two medium cooler of gas-liquid that can be used for motor cooling.
Background technology
motor is a kind of conventional rotary electric machine electric energy conversion being become mechanical energy.Lathe, water pump, need motor to drive; Electric locomotive, elevator, need motor to draw.Electric fan in family life, refrigerator, washing machine, even various motor toy all be unable to do without motor.Motor has been applied in the various aspects in modern society's life.Motor, in use due to the existence of various loss, makes temperature constantly raise, and in order to normal use, cooling is even more important.As do not cooled it well, the useful life of motor can be affected.If the heat-sinking capability of motor is poor, then motor temperature can be caused too high, the useful life of motor can be affected, cause the problems such as deadlock, the life security of operator time serious, can be threatened.
the type of cooling of motor has self cool, from fan cooling and forcing functions.Self cool is without any servicing unit, and rely on the flowing cool motors that outside air is spontaneous completely, radiating efficiency is not high, is applicable to small-sized motor; Install fan additional on motor side from fan cooling, the artificial heat radiation accelerating the flow faster motor of surrounding motors air, good heat dissipation effect and structure are simply easy to realize, and are widely used in industrial circle at present; Forcing functions is generally only used in large-size machine, and be electric motor temperature reduction by cooling fluid (be generally oily medium, use aqueous medium individually), radiating efficiency is high but system is comparatively complicated, is generally only applied to high capacity motor.
in industrial motor, comparatively extensive from fan cooling application, surrounding air directly enters motor interior and cools, and motor heat is directly taken away and is discharged in the environment of surrounding by cold air.Air mainly contains three kinds at the track route of motor interior.One is that axially cold air enters from motor one end, discharges from other one end.As long as one end can fill larger-diameter fan, just can obtain good cooling effect, core structure is compacter.Shortcoming is that draft loss is comparatively large, along motor reel to temperature distributing disproportionation even, the motor that the capacity that is generally used for is less.Another kind is radial, and cold air enters from motor two ends, discharges from the radial ducts of iron core.Its shortcoming is because two ends all will fill fan, therefore the external diameter of fan can only be less than the external diameter of rotor, limits the ability of fan, and needs radial ventilation groove, makes motor size bigger.Advantage is that drafting efficiency is higher owing to using aerofoil fan, and area of dissipation is comparatively large, along motor reel to temperature more even.Also have one to be axially ventilates with radial compound, its combined axis designs to the advantage of ventilating with both radial directions, have good ventilating and cooling effect, and temperature comparatively evenly, but structure is more complicated.
comparatively conventional is axially from fanning cooling at present, installs heat-dissipating cover plate, effectively can cool hot-air, be dispersed in air by the heat of motor in fan periphery.The body of motor makes axial fin, and the increase body of motor and the contact area of air make the body of motor dispel the heat to air fully.The heat-dissipating cover plate installed additional outside motor body can guide the flow direction of fan air on the one hand, can improve the overall radiating efficiency of motor on the other hand to the hot-air heat radiation of the heat absorption of inflow motor.Although improve the body profile of motor, do not improve for heat-dissipating cover plate, the heat-sinking capability of heat-dissipating cover plate improves space in addition further.So the appearance improvement carried out for heat-dissipating cover plate can improve the radiating efficiency of whole motor, improving the service behaviour of motor, process simple, practical and spend cheap, being applicable to major part from fanning cool motors.
