Abstract
The invention relates to a motor controller and a device for fixing and heat radiation of MOS transistors of the motor controller. A direct current motor controller comprises a PCB, a radiator and MOS transistors, the PCB is fixed on the top of the radiator, and the MOS transistors are fixed on side walls of the radiator.
Description
Technical field
The present invention relates to a kind of high-power brushless DC motor controller, particularly a kind of metal-oxide-semiconductor fixes heat abstractor.
Background technology
Before the present invention, for the assembling of some brushless direct current motor controllers, metal-oxide-semiconductor is plugged one by one, and then each metal-oxide-semiconductor is welded on pcb board.Because pcb board size is comparatively large, metal-oxide-semiconductor size is less, and metal-oxide-semiconductor is in the middle of PCB and fin, thus metal-oxide-semiconductor is difficult to good dress on a heat sink.During installation, contraposition and lock screw are installed again one by one.To take time so very much and efficiency is low, inconveniently easily to loosen owing to installing simultaneously, poor to making loose metal-oxide-semiconductor contact bad radiating effect with fin, inside instability, useful life is low.
summary of the invention
In view of this, the metal-oxide-semiconductor that the invention provides a kind of convenience stable again fixes heat abstractor.
A kind of electric machine controller metal-oxide-semiconductor fixes heat abstractor, and comprise radiator, top and a pcb board of this radiator are fixed, and the sidewall of this radiator is fixed with metal-oxide-semiconductor.
A kind of DC motor controller, comprise pcb board, radiator and metal-oxide-semiconductor, this pcb board is fixed on the top of this radiator, and this metal-oxide-semiconductor is fixed on the sidewall of this radiator.
Compared with traditional controller radiator mounting means, this product can accomplish that production technology is simple, radiator and metal-oxide-semiconductor is easy for installation, metal-oxide-semiconductor good heat dissipation effect, efficiency are high, improve the reliability and stability of controller.
Below in conjunction with accompanying drawing and embodiment, the present invention is further described.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that high-power brushless DC motor controller metal-oxide-semiconductor in one embodiment of the present invention fixes heat abstractor.
The vertical view of Fig. 2, press strip of the present invention 4.
The end view of Fig. 3, press strip of the present invention 4.
Embodiment
Number in the figure corresponding component is as follows:
1-radiator dog screw, 2-PCB plate, 3-insulation spacer, 4-press strip, 5-MOS pipe, 6-radiator 7-housing screw
As shown in Figure 1, when metal-oxide-semiconductor of the present invention fixes heat abstractor assembling, first pcb board 2 and radiator 6 are fixed together by radiator dog screw 1, the end by radiator set screw 1 passes pcb board 2 and the rear top screwing in radiator 6 of insulation spacer 3 successively.After this, metal-oxide-semiconductor 5 is attached on the sidewall of radiator 6, then compresses metal-oxide-semiconductor 5 with press strip 4, then by housing screw 7, metal-oxide-semiconductor 5 is fixed on radiator 6.
The technical staff understanding the intent of the present invention can be appreciated that, the installation method of above-mentioned electric machine controller metal-oxide-semiconductor heat abstractor is fixed by four, bottom screw and pcb board, adopt the most practical and effective stretcher type fixed mode with Time Controller upper and lower bridge arm metal-oxide-semiconductor, make fin, wiring board and metal-oxide-semiconductor efficient combination.High-power brushless DC motor controller power height electric current is large, caloric value large needs uses the radiator of larger area to dispel the heat, we use metal-oxide-semiconductor, wiring board and fin integrated solid mould-fixed to drive radiator ambient air circulate and take away heat, and we have reserved four screw hole positions in radiator and cover top portion and controller housing and radiator have been combined completely and add the hot blast that gas channel makes radiator bring out to can be good at forwarding outside to from controller housing.
The present invention widely uses high-power brushless DC motor controller.
The present invention is not limited to above-mentioned execution mode, adopts the structure identical or approximate with the above embodiment of the present invention, and other high-power brushless DC motor controller obtained, all within protection scope of the present invention.。
