Abstract

The utility model discloses rear cover, heat dissipation aluminium block unitary modules to control fan motor, including electric machine casing, control module, carbon brush component and the motor rear cover for being connected to electric machine casing rear end, rotor axis of electric stretches out outward from the front cover of electric machine casing, it is characterised in that:The rear end of motor rear cover is equipped with heat dissipation aluminium block, and heat dissipation aluminium block and motor rear cover use integrally formed aluminium casting structure, and heat dissipation aluminium block is made into multiple form of grooves in a circumferential direction, and the front/rear end of axial fenestra perforation motor rear cover is equipped between adjacent grooves.The utility model height dimension is small, and has great heat radiation effect.

Description

Rear cover, heat dissipation aluminium block unitary module control fan motor
Technical field
The utility model relates to a kind of radiator fans, and in particular to a kind of module control of radiator fans Fan motor.
Background technique
Radiator fans are driven by fan motor, and some fan motor band control modules pass through control module Control fan motor can be achieved cold air blast velocity is changed according to operating condition at any time.In the prior art, the height of control module fan motor It is generally large to spend size, since installation space is limited on vehicle, so bringing very big inconvenience to installation, while to keep module control The great heat radiation effect of fan motor, it is also desirable to control module fan motor height dimension with higher.
Summary of the invention
In view of the deficiencies in the prior art, it is small that the utility model provides a kind of height dimension, and has great heat radiation effect Rear cover, heat dissipation aluminium block unitary module control fan motor.
The utility model adopts the following technical scheme that complete:
Rear cover, heat dissipation aluminium block unitary module control fan motor, including electric machine casing, control module, carbon brush component and It is connected to the motor rear cover of electric machine casing rear end, rotor axis of electric stretches out outward from the front cover of electric machine casing, it is characterised in that:Electricity The rear end of machine rear cover is equipped with heat dissipation aluminium block, and heat dissipation aluminium block and motor rear cover use integrally formed aluminium casting structure, and radiate aluminium block It is made into multiple form of grooves in a circumferential direction, the front/rear end of axial fenestra perforation motor rear cover is equipped between adjacent grooves.
Control module is installed in the rear end face of motor rear cover, and heat dissipation aluminium block is trapped among the periphery of control module, after motor The right half part of lid front end face is equipped with recess cavity to accommodate the installation of carbon brush component, and left-half is then equipped with radiating boss, dissipates The rear end face of hot boss, which has, empties cavity, and the electronic component for protruding from control module PCB surface, which is located at, to be emptied in cavity.
Axial pass trough, the heat dissipation aluminium block groove front and back of axial pass trough and corresponding position is arranged in radiating boss in peripheral side Between be mutually communicated.
In above-mentioned technical proposal, carbon brush component and control module are installed in the front/rear end of motor rear cover respectively, because Left-half is only reserved for motor rear cover front end face, and recess cavity is set to accommodate carbon brush component, and right side is not required to setting and is recessed Cavity but setting radiating boss, and the rear end face of radiating boss have empty cavity, make to protrude from control module wiring board The electronic component on surface, which is located at, empties in cavity, so, motor rear cover and the carbon brush component being installed on it and control module The axial dimension of entire assembly can be substantially reduced, therefore compact-sized, can greatly reduce motor height dimension.Together When, the rear end of motor rear cover is equipped with heat dissipation aluminium block, and heat dissipation aluminium block and motor rear cover use integrally formed aluminium casting structure, heat dissipation Aluminium block is trapped among the periphery of control module, and heat dissipation aluminium block is made into multiple form of grooves in a circumferential direction, is equipped between adjacent grooves The front/rear end of axial fenestra perforation motor rear cover;And axial pass trough, axial pass trough is arranged in radiating boss in peripheral side It is mutually communicated between the heat dissipation aluminium block groove front and back of corresponding position.So, when fan motor is run, the wind that fan generates can Cooling directly is blowed to the periphery of motor rear cover, the heat that control module and motor operating generate is taken away, is had Great heat radiation effect.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the shape assumption diagram of the utility model;
Fig. 2 is the front direction three-dimensional view of motor rear cover;
Fig. 3 is the rear direction three-dimensional view of motor rear cover;
Fig. 4 is the rear direction plan view of motor rear cover.
Specific embodiment
As shown, the rear cover of the utility model, heat dissipation aluminium block unitary module control fan motor, including electric machine casing 11, control module 7, carbon brush component 2 and the motor rear cover 1 for being connected to 11 rear end of electric machine casing, rotor axis of electric 9 is from electric machine casing Front cover 10 stretch out outward, the rear end of motor rear cover 1 be equipped with heat dissipation aluminium block 6, heat dissipation aluminium block 6 and motor rear cover 1 using one at The aluminium casting structure of type, heat dissipation aluminium block 6 are made into multiple 5 forms of groove in a circumferential direction, axial window are equipped between adjacent grooves 5 The front/rear end of the perforation of hole 8 motor rear cover 1.Control module 7 is installed in the rear end face of motor rear cover 1, and heat dissipation aluminium block 6 is trapped among The periphery of control module 7, the right half part of 1 front end face of motor rear cover are equipped with recess cavity to accommodate the installation of carbon brush component 2, a left side Half part is then equipped with radiating boss 3, and carbon brush component 2 is provided only with two carbon brush 21, and two carbon brush 21 are mutually an angle of 90 degrees and are laid, The rear end face of radiating boss 3, which has, empties cavity(It is not drawn into figure), protrude from the electronics of 7 inner surface of control module wiring board Element, which is located at, to be emptied in cavity.Axial pass trough 4 is arranged in radiating boss 3 in peripheral side, and axial pass trough 4 is dissipated with corresponding position It is mutually communicated between hot 5 front and back of aluminium block groove.
