Abstract
The invention relates to a cooling device for a vertical motor of a double-layer structure. The cooling device (7) is of an integral structure and is composed of a draught fan (1) and an air-water cooler (2). The draught fan (1) and the air-water cooler (2) are located between an inner side plate (5) and an outer side plate (4) of the vertical motor of the double-layer structure, and the draught fan (1) and a stator core (6) are located on the same horizontal plane. The outer side plate (4) is in contact with the stator core (6), and the air-water cooler (2) is fixed to the outer side of the outer side plate (4) through a bolt. The draught fan (1) penetrates through the inner side plate and then is fixed to the outer side of the air-water cooler (2) through a bolt. The cooling device solves the problem that a traditional cooling device cannot be used for the vertical motor of the double-layer structure, the key parts, namely the draught fan and the air-water cooler of the whole cooling device are of an integrated structure and are installed between the inner side plate and the outer side plate of the motor, and the size of the motor is not increased. A motor cooling medium in the whole cooling device is air, the air circulates independently in the motor and does not exchange with external air, and the protection performance of the motor is good.
Description
Technical field
The present invention relates to a kind of double-decker vertical machine cooling device.
Background technology
At present, the vertical machine that some hot environment uses, support side plate adopts double-decker; between interior plate and outer panel, spacing is comparatively large, can completely cut off in outside by high ambient temperature, effectively avoids hot environment on the impact of motor winding and iron core; protection motor, extends motor useful life.But because motor adopts double-decker, motor side plate is divided into interior plate and outer panel, and traditional structure vertical machine cooling device is generally directly installed on side plate, after in motor room, hot-air enters cooling device by side plate, hot-air directly and surrounding air exchange, cooling motor.But sided configuration vertical machine is divided into interior plate and outer panel due to side plate, if cooling device is arranged on outer panel, in motor room, hot-air is by after entering the gap between interior plate and outer panel after interior plate, effectively cannot enter the cooling device on outer panel, cooling effectiveness is low, does not meet instructions for use.
Summary of the invention
The critical component blower fan and the air/water cooler that the object of the invention is to design a kind of whole cooling device are structure as a whole, and are arranged between motor interior plate and outer panel, additionally do not increase the double-decker vertical machine cooling device of motor volume.Technical scheme of the present invention is: a kind of double-decker vertical machine cooling device, cooling device (7) is overall structure, be made up of blower fan (1) and air/water cooler (2), blower fan (1) and air/water cooler (2) position are positioned between double-decker vertical machine interior plate (5) and outer panel (4), blower fan (1) and stator core (6) are in same level, outer panel (4) contacts with stator core (6), air/water cooler (2) is bolted on outer panel (4) outside, blower fan (1) is through being bolted on air/water cooler (2) outside after interior plate.
Cooling device (7) forms overall structure together with blower fan (1) is interconnected in the horizontal direction with air/water cooler (2), the fan blade group that blower fan (1) has two covers separate, purge direction respectively vertically upward and vertically downward, air/water cooler (2) has independent water piping system, with water inlet and the delivery port of independent loops.
Function of the present invention is cooling double-decker vertical machine, cooling process is that motor internal hot-air is extracted out from stator core by blower fan, hot-air becomes cold air after air/water cooler cooling, cold air enters blower fan, driven respectively to upper current downflow by blower fan, after interior plate upper and lower opening, flow through motor internal, cold air flows through motor room and becomes hot-air again after cooling motor, hot-air finally enters air/water cooler, enter the hot-air in air/water cooler and the recirculated cooling water in air/water cooler carries out heat exchange, heat is taken away rear hot-air from recirculated cooling water and is become cold air, last cold air enters blower fan and completes circulation.
Double-decker vertical machine cooling device a kind of special cooling device for double-decker vertical machine as shown in Figure 1, critical piece comprises blower fan (1), air/water cooler (2).Blower fan (1) and air/water cooler (2) form one, are arranged between interior plate (4) and outer panel (5), are positioned at same level line with stator core (6).Motor internal hot-air is extracted out from stator core (6) by blower fan (1), hot-air becomes cold air after air/water cooler (2) cooling, cold air enters blower fan (1), driven respectively to upper current downflow by blower fan (1), after interior plate (4) upper and lower opening, flow through motor internal, cold air flows through motor room (3) and becomes hot-air after cooling motor, hot-air finally enters air/water cooler (2), enter the hot-air in air/water cooler (2) and the recirculated cooling water in air/water cooler (2) carries out heat exchange, heat is taken away rear hot-air from recirculated cooling water and is become cold air, last cold air enters blower fan (1) and completes circulation.Whole cooling device coolant is air, and air, in motor internal independent loops, does not exchange with extraneous air, and the heat that motor produces finally is taken away by the recirculated cooling water in air/water cooler (2).
Advantage of the present invention: this cooling device solves the problem that conventional motors cooling device cannot be used for double-decker vertical machine, the critical component blower fan of whole cooling device and air/water cooler are structure as a whole, be arranged between motor interior plate and outer panel, additionally do not increase the volume of motor.In whole cooling device, motor coolant is air, and air, in motor internal independent loops, does not exchange with extraneous air, and motor protection is functional.The heat that motor produces finally is taken away by the recirculated cooling water in air/water cooler, does not produce additional heat to environment.The present invention efficiently solves traditional cold radiator cooler for the low problem of cooling effectiveness during double-decker vertical machine, cooling device is installed directly on interior plate, and fixed by outer panel, make hot-air in motor room by directly entering cooling device after interior plate, improve cooling effectiveness.The double-decker vertical machine cooling device that the present invention relates to solves the cooling effectiveness problem of double-decker vertical machine cooling device, has opened up the frontier of double-decker vertical type motor cooling pattern.
