Summary of the invention
The purpose of this utility model provides a kind of insulation and heat radiation is good, the simple liquid-cooled motor controller of processing technology.
The purpose of this utility model is achieved in that
The liquid-cooled motor controller, to contain power device electric machine controller the circuit board insulating supporting the sealing can in, be filled with the liquid of insulating heat-conductive in the can, be provided with the heat expansion space of liquid between can inwall and the liquid, what the wire insulation of connection electric machine controller sealed draws outside the can.
Above-mentioned can at least three faces are boxes that aluminium or copper material are made.
Above-mentioned liquid is transformer oil or insulating oil or silicone oil or the conduction oil of insulating heat-conductive.
The heat energy that power device work on the said motor controller circuit board produces passes through the liquid transfer of insulating heat-conductive to can, utilizes the natural convection air heat radiation through can again.
The circuit board of above-mentioned controller by the metallic conduction post on the roof and the draw-in groove on nut and the two side with the circuit board insulating supporting of electric machine controller in the can of sealing.
Insulated by insulation cushion between the roof of above-mentioned can and the large electric current metallic conduction post, and sealed with epoxy resin and sealing gasket.
Above-mentioned metallic conduction post directly is electrically connected with the power supply incoming junction of electric machine controller circuit plate and the three-phase tie point of drive motors from the can top respectively.
The little current feed of above-mentioned electric machine controller circuit plate is drawn can by the sealing device encapsulation process.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the utility model adopts the outside heat conduction of liquid, the heat that the liquid that the simple and good heat conductivity 2 of processing technology, the utility model adopt insulating heat-conductive produces during with the power device work of electric machine controller passes to the can wall from all quarter, heat transfer efficiency is high, rapid heat dissipation, electric machine controller heats up and to compare conventional way and want slow many, has guaranteed normal operation and the long service life of controller.
3, the utility model is owing to adopt the liquid of insulating heat-conductive, and its insulation property are better than the insulating material such as insulating paper, insulation cushion, and this is because the insulating material such as insulating paper, insulation cushion cause insulation hidden danger easily in manufacturing, installation, maintenance etc.
4, the power device on the electric machine controller circuit plate of the present utility model need not to carry out fastening with the metal heat-conducting thing, the common great majority of quantity of adding present technical reason power device are more than 10 even nearly 48, thereby have greatly reduced labor content.
5, the large electric current of the utility model connects from the electric machine controller circuit plate corresponding electric connection point and directly vertically draws with the metallic conduction post, thereby has at utmost reduced electrical loss.
6, the metallic conduction post that connects of the large electric current of the utility model is directly installed on the electric machine controller top, with the motor assembly connection in deducted the operation that conventional way will be removed link again.
7, the circuit board that the draw-in groove of the metallic conduction post complexed metal box that connects of the large electric current of the utility model simultaneously can the fixed electrical machinery controller, thus installation procedure reduced.
8, the utility model is applicable to the electric machine controller of high reliability.
