Abstract
The utility model provides a motor driving module having an improved heat dissipating structure and relates to a motor driving module. A prior motor driving module has complicated assembly, high cost, complicated circuit wire arrangement and low safety and reliability. The motor driving module having the improved heat dissipating structure in the utility model includes a PCB, a driving IPM (Intelligent Power Module) arranged on the PCB and a fixed support arrange below the PCB. The PCB is fixed on the fixing support through a connecting piece. It is characterized in that the driving IMP is disposed below the PCB. An insulating block used for heat conduction is arranged between the driving IPM and the fixed support. The insulating block transmits heat of the driving IPM to the fixed support. The fixed support works as a main component for dissipating heat. Therefore, not only the heat dissipation requirement is met, but also a heat dissipater and an installing and fixing piece of the heat dissipater in the prior art are removed. Thus, the cost is reduced and the installation is simplified. Moreover, the insulating block can work as a supporting block to keep the distance between the fixed support and the PCB, thereby guaranteeing the electric creep distance and improving the reliability of the motor driving module having the improved heat dissipating structure.
Description
Technical field
The utility model relates to a kind of motor drive module.
Background technology
Existing motor drive module is as shown in Figure 1, includes pcb board 5, drives IPM 4, fixed support 1, support fixed screw 2, aluminium section bar fin 3, electronic devices and components such as electric capacity 6, fin fixed screw 7.Its fit is that aluminium section bar fin 3 is pressed on the driving IPM 4 through fin fixed screw 7, is fixed on PCB drive plate 5 plates.PCB drive plate 5 is installed in the shortcoming that this structure exists on four installing holes of fixed support 1 through support fixed screw 2 be that assembling is complicated, and cost is high, and wiring is complicated, and security reliability is low.
The utility model content
The technical problem that the utility model will solve and the technical assignment of proposition are that the prior art scheme is improved and improved, and a kind of motor drive module of improveing radiator structure are provided, with the purpose that reaches easy to assembly, cost is low, safe and reliable.For this reason, the utility model is taked following technical scheme.
A kind of motor drive module of improveing radiator structure; Comprise pcb board; Be located at driving IPM on the pcb board, be located at the fixed support of pcb board below; Described pcb board is fixed on the fixed support through connector, it is characterized in that: described driving IPM is located at the below of pcb board, drives between IPM and the fixed support and is provided with the collets that are used for heat conduction.The heat that collets will drive IPM passes to fixed support, and fixed support had both reached the heat radiation requirement as the heat radiation critical piece, removed radiator of the prior art and mounting fixing parts thereof again, reduced cost, and simplified and installed; Collets also can be used as back-up block in addition, keep the distance between fixed support and the pcb board, have guaranteed electric creepage distance, increase reliability of products.The collets material can adopt the silica gel of good heat conductivity and insulation.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Described collets are fixed on the lower surface that drives IPM through tack coat, and the lower surface of collets and support bracket fastened upper surface are close to.Collets lower surface and fixed support are close to can reduce thermal resistance, improves radiating effect.Tack coat can be adhesive tape.
Establish the support column of a plurality of hollows between described fixed support and the pcb board, screw passes pcb board, support column and fixed support and is spirally connected and makes pcb board be fixed on the fixed support and collets are clipped between pcb board and the fixed support.
Beneficial effect: the heat that collets will drive IPM passes to fixed support, and fixed support had both reached the heat radiation requirement as the heat radiation critical piece, removed radiator of the prior art and mounting fixing parts thereof again, reduced cost, and simplified and installed; Collets also can be used as back-up block in addition, keep the distance between fixed support and the pcb board, have guaranteed electric creepage distance, increase reliability of products.
