Description

A stamped flow channel for a liquid cooling plate, a liquid cooling plate Technical Field

[0001] This utility model belongs to the field of heat dissipation technology for battery cell modules, and specifically relates to a stamped flow channel and a liquid cooling plate. Background Technology

[0002] Liquid cooling plates are widely used in electronic devices and electric vehicles, their main function being to dissipate heat from the battery cell modules by circulating coolant through liquid cooling channels. During the manufacturing process of liquid cooling plates, the brazing quality of the substrate and flow channel edges directly affects the sealing and reliability of the liquid cooling plate. However, in existing technologies, the stamped flow channels of liquid cooling plates often do not cover the edges of the cold plate, causing the cold plate to soften under high temperatures in the tunnel brazing furnace. This can easily lead to the substrate and flow channel plates opening up, resulting in coolant leakage and affecting the normal operation of the equipment.

[0003] Because the stamping flow channel cannot cover the edge of the cold plate, brazing fixtures are often required to support this blank space, which leads to complex fixture design, lack of universality, and increased production costs. Summary of the Invention

[0004] The purpose of this utility model is to provide a stamped flow channel for a liquid cooling plate and a liquid cooling plate, which solves the problem that the stamped flow channel of the existing liquid cooling plate cannot cover the edge of the cold plate, causing the cold plate to soften when heated at high temperature in the tunnel brazing furnace, which easily leads to the substrate and flow channel plate opening and coolant leakage.

[0013] Corner flow channel, the corner flow channel is set at the two inclined edges of the trapezoidal plane segment;

[0014] The first, second, third, and fourth flow channels are distributed sequentially from the trapezoidal plane segment to the rectangular plane segment. The outer edges of the flow channels are connected to inlet or outlet channels, and the middle flow channels are connected to inlet or outlet channels.

[0015] Preferably, a first vent hole is provided along the two inclined edges of the trapezoidal plane segment.

[0036] Example 1

[0037] As shown in Figures 1-3, this embodiment provides a stamped flow channel for a liquid cooling plate, which is disposed on the liquid cooling plate. The liquid cooling plate has a trapezoidal planar segment 7 and a rectangular planar segment 8, and the long base of the trapezoidal planar segment 7 is connected to any short edge of the rectangular planar segment 8. The channel includes:

[0038] The outer edge of the flow channel 1 is distributed along the three edges of the rectangular planar segment 8. The three edges distributed along the outer edge of the flow channel 1 do not include the short edge that connects to the long base of the trapezoidal planar segment 7.

[0039] Central flow channel 2 is distributed in the middle of trapezoidal planar segment 7 and rectangular planar segment 8;

[0040] The first flow channel 3 is distributed in the trapezoidal plane section 7, and the first flow channel 3 is connected to the middle flow channel 2 and the outer edge flow channel 1 respectively;

[0041] The second flow channel 4 is distributed in the rectangular planar section 8 and is connected to the middle flow channel 2 and the outer edge flow channel 1 respectively.

[0042] The third flow channel 5 is distributed in the rectangular planar section 8. The second flow channel 4 is connected to the middle flow channel 2 and the outer edge flow channel 1 respectively.

[0043] The fourth flow channel 6 is distributed in the rectangular planar section 8, and the second flow channel 4 is connected to the middle flow channel 2 and the outer edge flow channel 1 respectively;

[0044] Corner flow channel 13 is set on the two inclined edges of the trapezoidal plane segment 7; by setting corner flow channel 13 on the two inclined edges of the trapezoidal plane segment 7, the strength of the cold plate is improved and the opening problem is solved.

[0045] Among them, the first flow channel 3, the second flow channel 4, the third flow channel 5 and the fourth flow channel 6 are distributed sequentially from the trapezoidal plane segment 7 to the rectangular plane segment 8. The outer edge of the flow channel 1 is connected to the inlet channel or the outlet channel, and the middle flow channel 2 is connected to the inlet channel or the outlet channel. That is, when the outer edge of the flow channel 1 is connected to the inlet channel, the middle flow channel 2 is connected to the outlet channel, and vice versa. The inlet channel and the outlet channel extend inward from the outer wall of the liquid cooling plate.

[0046] The coolant is distributed sequentially from the trapezoidal plane segment 7 to the rectangular plane segment 8 through the first flow channel 3, the second flow channel 4, the third flow channel 5, and the fourth flow channel 6, ensuring that the coolant flows from the inlet channel into the outer edge flow channel 1, and then flows to the first flow channel 3, the second flow channel 4, the third flow channel 5, and the fourth flow channel 6 respectively. The coolant in the first flow channel 3, the second flow channel 4, the third flow channel 5, and the fourth flow channel 6 all flow from the middle flow channel 2 to the outlet channel, which fully dissipates heat from the battery cell module.

[0047] First exhaust holes 12 are also provided along the two inclined edges of the trapezoidal plane segment 7. This arrangement allows gas to flow out from inside the flow channel plate, reducing the formation of bulges due to trapped gas.

[0048] A second vent 9 is provided between the first flow channel 3 and the second flow channel 4. This arrangement allows gas to flow out from inside the flow channel plate, reducing the formation of bulges due to trapped gas.

[0049] A first support channel 14 is provided between the first flow channel 3 and the outer edge flow channel 1.

[0050] A third vent 10 is provided between the second flow channel 4 and the third flow channel 5. This arrangement allows gas to flow out from inside the flow channel plate, reducing the formation of bulges due to trapped gas.

[0051] A fourth vent 11 is provided between the third flow channel 5 and the fourth flow channel 6. This arrangement allows gas to flow out from inside the flow channel plate, reducing the formation of bulges due to trapped gas.

[0052] A second support channel 15 is provided between the fourth channel 6 and the middle channel 2.

[0053] There are multiple second support channels 15, which are evenly distributed between the fourth channel 6 and the middle channel 2.

[0054] Example 2

[0055] As shown in Figures 1-3, this embodiment provides a liquid cooling plate, which includes a liquid cooling plate body and a stamped flow channel, wherein the stamped flow channel is disposed on the liquid cooling plate body.

[0056] The liquid cooling plate body includes a substrate and a flow channel plate. The substrate and the flow channel plate are formed as a whole by brazing the edges. Stamped flow channels are processed on the flow channel plate. Corner flow channels 13 and first vent holes 12 are provided at the corner edges of the flow channel plate. The corner flow channels 13 support the edges of the substrate and the flow channel plate. When the edges of the substrate and the flow channel plate are brazed, the first vent holes 12 allow gas to flow out from the inside of the flow channel plate, reducing the formation of bulges due to trapped gas, improving the strength of the cold plate, and solving the problem of the substrate and the flow channel plate opening up.
