Embodiment
Below in conjunction with specific embodiments content of the present utility model is described.
As shown in Figure 1 to Figure 3, be a kind of motor controller structure schematic diagram with water-cooling base plate described in the utility model.
A kind of electric machine controller with water-cooling base plate described in the utility model, comprise: horizontally disposed radiating bottom plate 1 and drived control plate 2, drived control plate 2 is arranged at the top of radiating bottom plate 1, and is provided with insulating heat-conductive pad 3 between drived control plate 2 and radiating bottom plate 1; Drived control plate 2 comprises drive division 21 and control part 22, and drive division 21 top is provided with heat radiation aluminium block 4, and heat radiation aluminium block 4 is provided with power tube, and control part 22 etching has control circuit and jack-plug socket 5; Cooling water channel is provided with in radiating bottom plate 1.Specifically preferably, cooling water channel comprises water inlet 61, delivery port 62, flows into water channel 63 and back return-flow system 64, the one end flowing into water channel 63 connects water inlet 61, one end of back return-flow system 64 connects delivery port 62, the other end flowing into water channel 63 is connected with the other end of back return-flow system 64, flow into the snakelike horizontal arrangement of water channel 63 in radiating bottom plate 1, back return-flow system 64 is equidistantly arranged in juxtaposition in radiating bottom plate 1 with inflow water channel 63.Further with improvement, the drive division 21 of drived control the plate 2 and bottom being positioned at heat radiation aluminium block 4 is provided with heat-conducting metal coating 7, and the drived control plate 2 of heat-conducting metal coating 7 region being evenly distributed with the plated-through hole 71 of some vertical settings, plated-through hole 71 is engraved structure and is filled with heat-conducting medium in plated-through hole 71.
