Abstract

The invention provides a fastening radiating structure for a motor controller power supply module. The fastening radiating structure comprises a power supply module, a circuit board and a controller shell, wherein the fastening radiating structure also comprises a pressing plate; the pressing plate and the circuit board are fixed in the controller shell; the pressing plate is positioned above the circuit board; the bottom surface of the power supply module is fixed on the circuit board; and the top surface of the power supply module is embedded in a groove in the bottom surface of the pressing plate. The fastening radiating structure has the beneficial effects that the radiating performance of the power supply module under a conventional installation mode is improved; the loss is mainly conducted to the pressing plate through a thermal conductive insulation spacer and then is conducted to the controller shell for dissipation; and the pressing plate is made of aluminum alloy, so that the thermal conductivity property is far better than that of the circuit board, and the radiation efficiency is relatively high.

Description

A kind of fastening radiator structure of electric machine controller power module
Technical field
The invention belongs to machine field, especially relate to a kind of fastening radiator structure of electric machine controller power module.
Background technology
Electric machine controller is one of core component of electric automobile, and heat radiation is the key factor affecting its reliability.In general, if the working temperature of electronic devices and components exceedes certain limited field, the performance of components and parts will significantly decline, and can not steady operation, and then influential system reliability of operation.Therefore as the key element of automobile controller control unit, the heat dissipation problem of power module is most important.Usual power module welds on circuit boards by pin, and circuit board is arranged on controller base plate or housing by screw is unsettled.Under automobile-used environment, volume is large, the power module anti-vibration ability of Heavy Weight is poor.And due to installing space restriction, power module generally carries out Natural Heat Convection or is conducted heat on circuit board by pin shedding by its end face fin (or directly passing through Modular surface), and radiating effect is poor.
Summary of the invention
In view of this, the present invention is intended to the fastening radiator structure proposing a kind of electric machine controller power module.
Technical scheme of the present invention is achieved in that
A kind of fastening radiator structure of electric machine controller power module, comprise power module, circuit board and controller housing, also comprise pressing plate, it is inner that described pressing plate and circuit board are fixed on described controller housing, described pressing plate is positioned at the top of described circuit board, the bottom surface of described power module is fixed on described circuit board, and the end face of described power module embeds in the groove of described pressing plate bottom surface.
Further, also comprise heat-conduction insulation spacer, described heat-conduction insulation spacer is between the end face and the groove of described pressing plate of described power module.
Further, the underrun pin of described power module is welded on described circuit board.
Further, described circuit board and pressing plate are fixed by screws in described controller housing.
Further, described pressing plate is made up of aluminium alloy.
The advantage that the present invention has and good effect are: this structure improves the heat dispersion of power module under conventional mounting mode, and its loss major part is transmitted to pressing plate passes on controller housing by heat-conduction insulation spacer again and sheds.Pressing plate is manufactured by aluminium alloy, and heat conductivility is far superior to circuit board, and radiating efficiency is higher.This structure also improves the shock resistance of power module simultaneously, and heat-conduction insulation spacer, between power module end face and pressing plate groove, plays the effect of fastening, heat conduction and damping.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present invention
In figure:
1, power module 2, circuit board 3, pressing plate 4, heat-conduction insulation spacer
5, controller housing
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1, the present invention includes power module 1, circuit board 2 and controller housing 5, also comprise the pressing plate 3 that aluminium alloy is made, it is inner that described pressing plate 3 and circuit board 2 are fixed by screws in described controller housing 5, described pressing plate 3 is positioned at the top of described circuit board 2, the underrun pin of described power module 1 is weldingly fixed on described circuit board 2, and the end face of described power module 1 embeds in the groove of described pressing plate 3 bottom surface.Also comprise heat-conduction insulation spacer 4, described heat-conduction insulation spacer 4 is between the end face and the groove of described pressing plate 3 of described power module 1.
This structure improves the heat dispersion of power module under conventional mounting mode, and its loss major part is transmitted to pressing plate passes on controller housing by heat-conduction insulation spacer again and sheds.Pressing plate is manufactured by aluminium alloy, and heat conductivility is far superior to circuit board, and radiating efficiency is higher.This structure also improves the shock resistance of power module simultaneously, and heat-conduction insulation spacer, between power module end face and pressing plate groove, plays the effect of fastening, heat conduction and damping.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
