[0002] For the design of the heat dissipation water channel of the housing of a low-flow-resistance and high-performance motor controller, the main objective is to effectively manage the heat generated during the operation of the motor controller, cool the controller through the way of cold water circulation, and ensure its performance and reliability. However, during the water-cooling circulation process, only one water pump is equipped to provide the water supply circulation. When the water pump stops running and cannot provide water pressure, the water in the water-cooling housing will flow out through the water inlet and outlet, resulting in no water in the water-cooling housing to absorb and dissipate heat. Content of the Utility Model

[0003] The purpose of the utility model is to provide a low-flow-resistance and high-performance heat dissipation water channel for the housing of a motor controller, so as to solve the problem proposed in the above background technique that during the water-cooling circulation process, only one water pump is equipped to provide the water supply circulation. When the water pump stops running and cannot provide water pressure, the water in the water-cooling box will flow out through the water inlet and outlet, resulting in no water in the water-cooling box to absorb and dissipate heat.

[0022] The present invention provides a low-flow-resistance and high-performance motor controller housing heat dissipation water channel as shown in Figures 1-4 which includes a water cooling box 2 embedded in the upper left front side of the controller 5;

[0023] An inlet 1 is provided on the left side of the front end of the controller 5, and an outlet 6 is provided on the right side of the inlet 1. The inlet 1 and the outlet 6 are used to convey and discharge cold water into the water cooling box 2.

[0024] A fixing frame 7 is provided at the inlet 1 of the inner wall of the water cooling box 2;

[0025] A plurality of slots 11 are provided on the outer wall of the fixing frame 7, a tapered block 13 is provided on the inner wall of the fixing frame 7, and a spring 12 is provided between the upper end of the tapered block 13 and the inner wall of the fixing frame 7. The spring 12 is used to drive the tapered block 13 to move downward.

[0026] The tapered block 13 is fixedly arranged on the inner wall of the fixing frame 7 through the spring 12, and the tapered block 13 can be driven by the tension of the spring 12 to move forward and abut against the front side of the fixing frame 7. When the water pump conveys cold water into the water cooling box 2 through the inlet 1, the water pressure will push the tapered block 13 backward, so that the water flow is conveyed into the water cooling box 2 through the slots 11 on the surface of the fixing frame 7.

[0027] As shown in Figure 3 and Figure 4 on the front sides of the left and right ends of the outer wall of the fixing frame 7, fixing blocks 9 are provided. Fixing holes 14 are provided at the front ends of the two fixing blocks 9, and screws 10 are arranged in the two fixing holes 14. The fixing frame 7 is fixed to the inner wall of the water cooling box 2 through the screws 10 and the fixing blocks 9.

[0028] Insert the screw 10 into the fixing hole 14 of the fixing block 9, and fix the fixing frame 7 at the inlet 1 of the inner wall of the water cooling box 2 through the screw 10.

[0029] As shown in Figure 3 and Figure 4 a rubber ring 15 is provided on the inner wall of the opening of the fixing frame 7. The rubber ring 15 is used to increase the sealing performance of the plugging between the tapered block 13 and the opening of the fixing frame 7. The fixing frame 7, the fixing blocks 9, the spring 12 and the tapered block 13 are all made of stainless steel material, and the spring 12 is connected and fixed to the tapered block 13 and the fixing frame 7 by welding.

[0030] The conical block 13 can be driven forward by the tension of the spring 12 to abut against the front side of the fixed frame 7 and fit with the rubber ring 15, and the rubber ring 15 is used to increase the sealing performance between the conical block 13 and the fixed frame 7. The fixed frame 7, fixed block 9, spring 12 and conical block 13 made of stainless steel can avoid rusting.

[0031] As Figure 1 and Figure 2 shown, a water guide plate 8 is arranged on the inner wall of the water-cooled box 2. The water guide plate 8 is used to guide the flow direction of cold water. The water guide plate 8 and the water-cooled box 2 are made by an integral design. A sealing groove 3 is opened at the edge of the upper inner wall of the water-cooled box 2.

[0032] Water flows into the water-cooled box 2 through the slot 11 on the surface of the fixed frame 7. The cold water entering the water-cooled box 2 flows outwards from the water outlet 6 under the guidance of the water guide plate 8, so as to absorb the heat dissipated by the controller 5 and achieve a cooling effect.

[0033] The working principle of the present utility model: When the water pump conveys cold water into the water-cooled box 2 through the water inlet 1, the water pressure will push the conical block 13 backward, so that water flows into the water-cooled box 2 through the slot 11 on the surface of the fixed frame 7. The cold water entering the water-cooled box 2 flows outwards from the water outlet 6 under the guidance of the water guide plate 8, so as to achieve the effect of cooling the controller 5 by cold water circulation. When the water pump stops running, the water pressure cannot push the conical block 13, and the spring 12 will push the conical block 13 forward to fit with the rubber ring 15. When the conical block 13 fits with the rubber ring 15, the water inlet 1 will be blocked, thus preventing the entry of air, and forming the principle of atmospheric pressure to prevent water from discharging from the water outlet 6, and storing the water in the water-cooled box 2 to continue cooling the controller 5.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
