The MOS tube fixing and radiating structure is used for installation fixing and integral radiating of the MOS tube in the electromobile controller. A wedge-shaped cavity formed by a cavity thick protruding wall (111) and an arc boss (112) at the position of a casing (11) adjacent to the MOS tube. A transverse limit boss (113) is arranged in the wedge-shaped cavity. The MOS tube is arranged on the cavity thick protruding wall (111) of the wedge-shaped cavity. A soft wedge-shaped press strip (13) is plugged between the MOS tube and the arc boss (112). A traditional mode that an aluminum strip is matched with a fastening screw is replaced with the press strip mode to enable the MOS tube to be fixed in the cavity of a casing of the controller, installation program is simplified, the space of the cavity of the casing is saved, the casing wall is thickened, heat resistance is reduced, a better radiating effect is achieved, and the reliability of the electromobile controller is improved.
Description
Technical field
The invention belongs to electronic equipment and patch structure, especially relevant with electric motor car controller radiator structure technical field.
Because electric bicycle has environmental protection and energy saving, price is suitable, noiseless, and therefore characteristics such as facility obtain application more and more widely.Electric bicycle commonly used drives brshless DC motor by controller, so the heat dissipation design of entire controller has important role for electric bicycle performance and reliability.Present metal-oxide-semiconductor is fixing to reach heat-dissipating structure as shown in Figure 1.
In Fig. 1,1 is the controller aluminum hull, and 2 is that original controller mounted inside figure is the screw that is used for fixed housing, and 3 are the fixing aluminum strip of metal-oxide-semiconductor, and 4 is the metal-oxide-semiconductor of controller inside, and 5 is the pcb board of controller inside, and 6 is the aluminum strip hold-down screw.Metal-oxide-semiconductor 4 is fixed on the aluminum strip 3 by screw 6, and aluminum strip mainly plays heat absorption and conduction heat.
Yet from situation about using, the repair rate of controller is still higher, because the thermal diffusivity design defect of controller itself causes the shortening of controller physical life.
Summary of the invention
Above shortcoming in view of prior art the objective of the invention is, and a kind of fixing and heat-dissipating structure of controller metal-oxide-semiconductor with good heat radiating is provided.
The objective of the invention is to realize by following means.
Fixing and the heat-dissipating structure of controller for electric vehicle metal-oxide-semiconductor, the the installing and fixing and whole heat radiation of metal-oxide-semiconductor that is used for controller for electric vehicle inside, formed by shell, metal-oxide-semiconductor and hold-down mechanism, it is characterized in that, shell 11 has the wedge shape cavity that the thick protruding wall 111 of cavity and arc convex 112 constitute in itself and metal-oxide-semiconductor adjacent regions, and the wedge shape cavity is built-in with cross spacing boss 113; Metal-oxide-semiconductor places on the thick protruding wall 111 of wedge cavities intracoelomic cavity body; At metal-oxide-semiconductor and 112 caulkeds of arc convex soft wedge shape press strip 13 is arranged.
Adopt design as above, replacing traditional aluminum strip with the press strip mode joins the mode of trip bolt metal-oxide-semiconductor is fixed in the controller housing cavity, simplified installation procedure, saved the space of shell cavity, the thickening casing wall thickness has reduced thermal resistance, play better radiating effect, improved the reliability of controller for electric vehicle.

Embodiment
Below in conjunction with accompanying drawing structure of the present invention is described in further detail.
In Fig. 2,11 is controller aluminium shell, and 12 for being used for the screw of fixed housing, and 13 are the fixing press strip of metal-oxide-semiconductor, and 14 is the metal-oxide-semiconductor of controller inside, and 15 is the pcb board of controller inside.As shown in the figure, shell 11 has the wedge shape cavity that the thick protruding wall 111 of cavity and arc convex 112 constitute in itself and metal-oxide-semiconductor 14 adjacent regions, and the wedge shape cavity is built-in with cross spacing boss 113.Metal-oxide-semiconductor places on the thick protruding wall 111 of wedge cavities intracoelomic cavity body.At metal-oxide-semiconductor and 112 caulkeds of arc convex soft wedge shape press strip 13 is arranged.
Shell 11 has distinctive wedge shape cavity, the limit that it is adjacent with metal-oxide-semiconductor, and thickness can reach 7mm.This thicker die cavity wall has replaced the heat absorption conduction function of aluminum strip 3 among Fig. 1.And with the mode of Fig. 1, need all will be coated with heat-conducting silicone grease on the aluminum strip two sides, increased heat conducting thermal resistance; Adopt the mounting means of Fig. 2, only need to smear heat-conducting silicone grease at metal-oxide-semiconductor and aluminum hull contact-making surface, reduce thermal resistance, directly adopt aluminum hull heat absorption and heat radiation.
Soft wedge shape press strip 13 is wedge shape, adopt suitable soft partially metal material to make, press metal-oxide-semiconductor by wedge structure, have on its surface that contacts with metal-oxide-semiconductor and to be intended to reduce contact area in order to ventilation and heat and to increase the groove structure of footprint pressure, dwindle the contact area with metal-oxide-semiconductor, increase pressure, the metal-oxide-semiconductor location is more firmly fitted on the wall of chamber, improve the radiating effect of metal-oxide-semiconductor; Also can be by the crimp of self, adapt to the metal-oxide-semiconductor thickness deviation, also omitted metal-oxide-semiconductor dog screw 6 among Fig. 1 simultaneously, economization installation procedure.
In addition, be equipped with the through hole of mounting screw 12 near the shell 11 the cross spacing boss, screw 12 passes outer aluminium shell, and promotion press strip 3 will be fixing to the metal-oxide-semiconductor application of force by lozenges, also plays the effect that better fixing and simplification is installed.
Installation process of the present invention, as shown in Figure 3:
Step 1 neatly is assembled to metal-oxide-semiconductor 14 on the pcb board 15, coats heat-conducting silicone grease at metal-oxide-semiconductor 14 metal coverings, sticks heat conductive isolation sheet;
Step 2, the pcb board 15 that assembling is finished is 11 inner chamber notches from aluminum hull 11 1 ends along outer aluminium shell, push in the wedge shape cavity;
Step 3 slips into press strip 13 in the wedge-shaped slot from an end along metal-oxide-semiconductor 14 fronts;
Step 4 is installed screw 12 in the aluminum hull screw mounting hole, compress press strip by screw thread, and press strip 13 compresses metal-oxide-semiconductor 14 by wedge structure, finishes installation.
