Abstract
The utility model relates to a motor air cooling structure. The motor air cooling structure comprises a centrifugal fan and a connection air duct. The centrifugal fan is disposed on a rotating shaft at one end of an air outlet of a motor. The connection air duct comprises a wind shield I and a wind shield II. The centrifugal fan is disposed between the wind shield I and the wind shield II. The distance between one end of the wind shield I and one end of the wind shield II matches the width of the centrifugal fan. The distance between the other end of the wind shield I and the other end of the wind shield II matches the air outlet of the motor. The wind shield I and the wind shield II are circular rings with holes in the center. The inner ring of the circular ring of the wind shield I matches the outer ring of the fan. The outer ring of the circular ring of the wind shield I matches an arc rib plate I corresponding to a base. The inner ring of the circular ring of the wind shield II matches the outer ring of the fan. The outer ring of the circular ring of the wind shield II matches an arc rib plate II corresponding to the base. The motor air cooling structure is provided with the connection air duct between the air outlet of the motor and the blower, so that hot air exhausted by the blower is directly discharged through the air outlet, so as to be prevented from flowing into the inner part of the motor again. Thus, heat exchange inside the motor is ensured, and temperature rise of the motor is reduced, and heat exchange efficiency is improved.
Description
Technical field
The utility model relates to the air-cooled cooling structure of a kind of motor.
Background technology
Adopt air-cooled cooling motor, its centrifugal fan is generally installed on machine shaft, cooling air enters motor internal from a side of motor and becomes thermal current, thermal current axially enters rear flank in blast fan, compressed under the effect of centrifugal force, radially flow inflow outside motor or cooler exchange.Adopt the centrifugal fan of this kind of structure, owing to having certain distance between the outlet of fan thermal current and the air inlet of the external air outlet of motor or cooler, thereby cause part thermal current to reenter motor internal, heat exchanger effectiveness reduces, and the temperature rise of motor is higher.
Utility model content
The purpose of this utility model is to overcome above defect a kind of efficiency of heat exchange, air-cooled cooling structure of motor of reduction electric machine temperature rise of improving is provided.
The technical solution of the utility model is: the air-cooled cooling structure of a kind of motor, it comprises centrifugal fan, centrifugal fan is located in the rotating shaft of motor air outlet one end, also comprise connection air duct, described connection air duct comprises deep bead I and deep bead II, centrifugal fan is placed between deep bead I and deep bead II, distance and centrifugal fan width between deep bead I and deep bead II one end match, distance and motor air outlet between deep bead I and the deep bead II other end match, the annulus that deep bead I and deep bead II are middle perforate, annulus inner circle and the fan cylindrical of deep bead I match, the circular arc gusset I of the annulus cylindrical of deep bead I and support corresponding section matches, annulus inner circle and the fan cylindrical of deep bead II match, the circular arc gusset II of the annulus cylindrical of deep bead II and support corresponding section matches.
For the ease of installation and removal, described deep bead I and deep bead II are evenly split as two lobes or more than two lobes.
In order to improve useful life, the material of described deep bead I and deep bead II is fiberglass.
Effect of the present utility model is: owing to being connected air duct being provided with between motor air outlet and fan, thereby the hot blast that fan is discharged directly enters air outlet and discharges, avoid again flowing into motor internal, thereby guaranteed the heat exchange of motor internal, reduce the temperature rise of motor, improved heat exchanger effectiveness.
