[0024] Beneficial effects of the present invention:

[0025] (1) The first transmission pipe is supplied with water through the water supply mechanism, and the first transmission pipe supplies water to the second transmission pipe. The water entering the second transmission pipe drives the impeller, the transmission shaft, the connecting pipe and the grinding wheel to rotate. At the same time, the first transmission pipe is driven to rotate through the transmission mechanism, and the first motor drives the first mounting shaft and the second connecting plate to rotate, so that the grinding wheel can perform comprehensive multi-angle grinding on the surface of the liquid cooling plate after welding. At the same time, the supplied water is sprayed out through the flushing pipe to flush the grinding position, so that the grinding debris can be quickly flushed and discharged, which greatly improves the grinding effect of the surface of the liquid cooling plate after welding.

[0026] (2) The grinding wheel is fixed in a portable manner by means of a clamping mechanism in the connecting tube, and in combination with a grinding wheel feeding mechanism, the grinding mechanism can automatically replace grinding wheels of different sizes, thereby greatly improving the applicability of the grinding mechanism and also improving the grinding effect of the liquid cooling plate.

Then, the water in the water tank is pumped into the water spray pipe by the second water pump. Then, the water spray pipe flushes the debris left on the surface of the liquid cooling plate after grinding through the water spray head. At the same time, the moving mechanism drives the water spray pipe to move, and at the same time, the hot air is supplied to the drying pipe through the hot air blower. The hot air dries the cleaned surface of the liquid cooling plate through the drying hood on the drying pipe, thereby realizing the integrated processing of flushing and drying the debris and stains on the surface of the polished liquid cooling plate, which is convenient for subsequent spraying.

[0028] (4) Three flow channels are used for diversion at the inlet, each of which extends downward into four branches in parallel. The inlet parallel structure diverts the flow channels, which can appropriately reduce the pressure drop, and the flow distribution of each flow channel is uniform. At the same time, the parallel structure enables the coolant to be more evenly distributed among the battery cells through diversion and parallel flow, so that the heat is evenly dissipated, which improves the heat dissipation effect of the liquid cooling plate. At the same time, an accelerated spoiler structure is used to increase the flow rate and enhance the heat exchange, making the heat dissipation effect more prominent.

[0064] See also Figure 9-11 As shown, a liquid cooling plate with uniform heat dissipation includes a base plate 81, one side of the base plate 81 is pressed with three flow-dividing liquid cooling grooves 82 in parallel, the three flow-dividing liquid cooling grooves 82 are each divided into four branches connected in parallel, one side of the base plate 81 is pressed with a spoiler groove 83, one side of the base plate 1 is fixedly connected with a cover plate 84, and the cover plate 84 is welded with a water inlet pipe 85 and a water outlet pipe 86;

[0065] Three flow channels are used for diversion at the inlet, each of which extends downward into four branches in parallel. The inlet parallel structure diverts the flow channels, which can appropriately reduce the pressure drop, and the flow of each flow channel is evenly distributed. At the same time, the parallel structure enables the coolant to be more evenly distributed among the battery cells through diversion and parallel flow, so that the heat is evenly dissipated, which improves the heat dissipation effect of the liquid cooling plate. At the same time, an accelerated spoiler structure is used to increase the flow rate and enhance heat exchange, making the heat dissipation effect more prominent.
