Description

A kind of motor radiating structure

Technical field:

The utility model relates to a kind of motor radiating structure.

Background technology:

IPM module in the circuit board need to be installed a radiator in the IPM module for heat radiation fast.IPM module heat dissipating structure on the traditional circuit plate, usually adopt screw that wiring board is connected with radiator, radiator is fixed on the IPM module, when fastening wiring board and radiator with screw, the more difficult control of fastening force used, the stress that produces when fastening easily makes the wiring board distortion and causes components and parts inefficacy on wiring board, and need first to the radiator drilling and tapping when installing, complex procedures is installed trouble, and cost of labor is high.

Summary of the invention:

The purpose of this utility model is to provide a kind of motor radiating structure, and this is simple in structure, installs simple and easyly, connects fasteningly, and cost is low, good heat dissipation effect.

The purpose of this utility model is achieved by following technical proposals.

A kind of motor radiating structure, comprise wiring board, IPM module, radiator and geometrical clamp, geometrical clamp is installed in the circuit board, the pin that the IPM module is bearing on geometrical clamp and the IPM module is stretched out welds in the circuit board, and radiator is bearing on the IPM module and is fixed and presss from both sides the dog clutch chucking that stretches out both sides.

Geometrical clamp described above comprises substrate, the substrate both sides protrude upward some dog clutch, some elasticity clips are protruded in the bottom surface of substrate, elastic buckles clamps in the through hole of offering on wiring board and is stuck on the wiring board bottom surface, substrate is adjacent on the end face of wiring board, and the breach that dog clutch embedding radiator is offered and fastening are on the end face of radiator.

Scribble the thermal grease layer between radiator described above and IPM module.

Geometrical clamp described above is injection mo(u)lding.

The utility model compared with prior art, have following effect: 1) the utility model is by increasing by a geometrical clamp, geometrical clamp is installed in the circuit board, the pin welding that the IPM module is bearing on geometrical clamp and the IPM module is stretched out in the circuit board, radiator is bearing on the IPM module and is fixed and presss from both sides the dog clutch chucking that stretches out both sides, reduced the screw installation, can not cause components and parts damage on wiring board because of the need mounting screw, and need not the radiator drilling and tapping, simple in structure, install simple and easyly, connect fastening, cost is low, good heat dissipation effect; 2) geometrical clamp comprises substrate, the substrate both sides protrude upward some dog clutch, some elasticity clips are protruded in the bottom surface of substrate, elastic buckles clamps in the through hole of offering on wiring board and is stuck on the wiring board bottom surface, substrate is adjacent on the end face of wiring board, and dog clutch embeds breach that radiator offers and fastening on the end face of radiator, reasonable in design, install simple and easyly, connect fastening; 3) scribble the thermal grease layer between radiator and IPM module, be beneficial to quick heat radiating, radiating effect is better; 4) geometrical clamp is injection mo(u)lding, and is with low cost.

Embodiment:

Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one: as shown in Figures 1 to 4, the utility model is a kind of motor radiating structure, comprise wiring board 1, IPM module 2, radiator 3 and geometrical clamp 4, geometrical clamp 4 is arranged on wiring board 1, the pin 21 that IPM module 2 is bearing on geometrical clamp 4 and IPM module 2 is stretched out is welded on wiring board 1, and radiator 3 is bearing on IPM module 2 and is fixed and presss from both sides dog clutch 41 chuckings that stretch out 4 both sides.

Embodiment two: increase following technical characterictic on the basis of embodiment one: described geometrical clamp 4 comprises substrate 40, substrate 40 both sides protrude upward some dog clutch 41, some elasticity clips 42 are protruded in the bottom surface of substrate 40, elasticity clip 42 embeds 11 li of the through holes of offering on wiring boards 1 and is stuck on wiring board 1 bottom surface, substrate 40 is adjacent on the end face of wiring board 1, and the breach 31 that dog clutch 41 embedding radiators 3 are offered and fastening are on the end face of radiator 3.

Embodiment three: increasing following technical characterictic on the basis of embodiment two: scribble thermal grease layer 5 between radiator 3 and IPM module 2.

Embodiment four: increase following technical characterictic on the basis of embodiment one or embodiment two or embodiment three: geometrical clamp 4 is injection mo(u)ldings.

Because the application is mechanical field, ability those of ordinary skill apparent association obtains: the technical characterictic independent assortment of the increase that embodiment two, embodiment three and embodiment four mention is combined into new technical scheme with the technical scheme of embodiment one.

The utility model increases by a geometrical clamp 4, geometrical clamp 4 is arranged on wiring board 1, and the pin 21 that IPM module 2 is bearing on geometrical clamp 4 and IPM module 2 is stretched out is welded on wiring board 1, and radiator 3 is bearing on IPM module 2 and is fixed and presss from both sides dog clutch 41 chuckings that stretch out 4 both sides, reduced the parts screw, solved because the need mounting screw causes components and parts damage problem on wiring board, and need not the radiator drilling and tapping, simple in structure, install simple and easy, connect fasteningly, cost is low, good heat dissipation effect.
