Detailed Description
The utility model will be further described with reference to the accompanying drawings.
As shown in fig. 1, a liquid cooling plate 1 according to an embodiment of the present utility model includes an upper plate 11, a lower plate 12, a flow channel layer 13, and a flow disturbing layer 14, wherein the lower plate 12 is disposed opposite to the upper plate 11, the flow channel layer 13 is disposed between the upper plate 11 and the lower plate 12, and a flow channel for flowing cooling liquid is formed between the upper plate 11 and the lower plate 12. The turbulence layer 14 is disposed in the flow channel, as shown in fig. 2, the turbulence layer 14 includes a plurality of turbulence modules 141, the turbulence modules 141 are corrugated plates, and a plurality of grooves 100 for cooling liquid to flow are disposed on the turbulence modules 141.
The liquid cooling plate 1 of this embodiment includes the turbulent flow layer 14 that sets up in the runner, and turbulent flow layer 14 not only can increase the turbulent flow of coolant liquid, enlarges the heat transfer area, realizes better heat transfer effect, and the turbulent flow module 141 of wave plate form can also provide certain structural strength, makes liquid cooling plate 1 have higher structural strength, can independently bear the weight of battery package.
As shown in fig. 3, the cross-sectional shape of the grooves 100 is rectangular, and a plurality of grooves 100 are alternately arranged on the upper and lower surfaces of the spoiler 141, so that the top and bottom surfaces of the spoiler 141 can be in good contact with the upper and lower plates 11 and 12, respectively, and can directly exchange heat with the upper plate 11 while providing good support when the liquid cooling plate 1 is under pressure, thereby providing a better cooling effect.
In other embodiments, the cross-sectional shape of the recess 100 is trapezoidal, triangular or wavy, and the shape of the spoiler 141 is correspondingly changed.
As shown in fig. 4, the edge of the spoiler 141 has a quadrilateral shape or a triangular shape. In order to achieve a better heat exchange effect, the flow channels are usually designed to be in a curved state, as shown in fig. 5, and arrows in fig. 5 indicate the flow direction of the cooling liquid in the flow channels. In order for the spoiler 14 to perform a good function, the spoiler 141 should cover substantially the entire flow path. Therefore, the shape of the spoiler 141 is selected according to the position of the spoiler in the runner, so that the edge of the spoiler 141 is in various shapes such as triangle, right trapezoid, isosceles trapezoid, parallelogram, etc.
When the shape of the flow channel changes, the shape of the spoiler 141 may also change accordingly. In other embodiments, the edge of the spoiler 141 is fan-shaped to cope with the situation that the flow channel has a circular arc portion, and accordingly, the shape of the groove 100 is changed from a straight groove to a curved groove.
As shown in fig. 4, the confluence region 200 is formed by being spaced between two spoiler modules 141 adjacent to each other in the coolant flow direction. The cooling liquid flowing out of one turbolator 141 will first enter the confluence region 200, and then flow into the next turbolator 141 from the confluence region 200, so that all grooves 100 in the next turbolator 141 can receive the cooling liquid, and the cooling liquid will more uniformly enter the next turbolator 141, and the cooling effect of the liquid cooling plate 1 will be consistent.
