Abstract
The utility model relates to a motor cooling mechanism of hot air device of automobile which aims at utilizing small partial wind flow which is blown by the mainframe fan to realize the effective cooling to the electric motor on the condition of not change the self mechanism of the electric motor. The technical points are that: a wind outlet nozzle 3 is arranged on the body of a mainframe 1. End cover of an electric motor 5 is covered with a hat cover 7. A wind inlet nozzle 6 is arranged on the hat cover. A tube 4 connects the wind outlet nozzle and the wind inlet nozzle on the hat cover; then the small partial wind flow which in the mainframe entering the inside of the electric motor through the wind outlet nozzle, the tube, the wind inlet nozzle and the heat radiating holes which are arranged on the original electric motor so as to effectively cool the electric motor, in particular applied in the cooling of the fan motor of the hot air device of mini car.
Description
The utility model relates to a kind of motor cooling body of automotive heatingn system motor cooling body, particularly mid-get car heater.
The mid-get car heater utilizes the automobile engine cooling water waste heat, and the usefulness of warm braw and wind screen defrosting is provided in car by heater.As the motor of heater, send the air quantity of technical requirements in the certain power drive fan, reach every work efficiency and effective efficiency through airduct, because machine operation is at the warm braw mode of operation, effective cooling of motor is very important.Existing motor is to adopt natural cooling, as shown in Figure 1, often can not satisfy the cooling requirement under the electromotor high-temperature mode of operation, the time and et out of order.In case the temperature rise of motor is above standard, the consequence that often causes the motor stall to be burnt, thus influence all functions of whole heater.
The utility model purpose is not change under the situation of this body structure of motor, and the fraction air quantity that utilizes the main frame fan to send is realized the effective cooling to motor.
For achieving the above object, the fraction air quantity that the utility model utilizes the main frame fan to send enters electric motor end cap through an airduct, louvre by electric motor end cap enters motor internal, cause motor effectively to be cooled off down in working order, reach the normal purpose of electric machine temperature rise, its technical scheme is, on heater main frame body, air outlet tube mouth is set, be with cap on the end cap of motor, air intake pipe orifice is arranged on the cap, by flexible pipe with the air intake pipe orifice socket of the air outlet tube mouth on the main frame on cap.Fraction air quantity in the main frame enters motor internal through flexible pipe by the louvre on the electric motor end cap like this, and motor is cooled off.
Fig. 1 is existing automotive heatingn system main machine structure scheme drawing.
Fig. 2 is a kind of embodiment of the utility model, automotive heatingn system main machine structure scheme drawing.
Shown in figure, fan 2 is housed in this automotive heatingn system main frame 1, fan 2 is by motor 5 driven rotary, the air channel is carried, air outlet tube mouth 3 is set on the body of main frame 1, be with cap 7 on the end cap of motor 5, dotted portion is an electric motor end cap among the figure, an air intake pipe orifice 6 is arranged on the cap 7, flexible pipe 4 is with air intake pipe orifice 6 sockets of air outlet tube mouth 3 on cap, and the sub-fraction air quantity that the main frame internal fan produces is by air outlet tube mouth 3, flexible pipe 4, air intake pipe orifice 6, louvre on the original motor end cap enters motor internal, and motor is effectively cooled off, the motor running temperature is effectively controlled, and then guarantees the functions of use of heater.In the present embodiment, air outlet tube mouth adopts and the one-shot forming of main frame body, and the air intake pipe orifice on the cap is with the cap one-shot forming.Flexible pipe can adopt trunnion etc.
In sum, the utility model can not change under the structure situation of motor own, adopts simple technique side Case utilizes the main frame air quantity to realize effective cooling to motor, have rational in infrastructure, make simple, cost is low, The advantage that cooling effect is good. Be applicable to automobile, especially the fan electromotor of minicar heater is cold But.
