Description

Technical Field

[0001] The utility model relates to the technical field of cooling, in particular to a water cooling plate. Background Art

[0002] The battery pack is equipped with a battery module and a water-cooling plate. The battery module is supported on the water-cooling plate. The water-cooling plate has a flow channel. The cooling medium circulates through the flow channel to exchange heat with the battery module. In the prior art, the flow rates of the various flow channels inside the conventional water-cooling plate vary greatly, affecting the uniformity of the overall battery cell temperature. For example, Figure 1 A conventional water-cooling plate is provided. Its interior is composed of 16 diversion channels, with each group of four diversion channels forming a flow channel. The diversion channels are separated by sheet metal (dividing ribs 6 or diversion ribs 7). In conventional water-cooling plates, the flow channels have the same sheet metal length. This leads to uneven flow distribution at channel bends before the flow enters the next group of channels, resulting in significant differences in flow rates within each group of four channels. To achieve flow balance within the channels, the width of each channel or diversion channel is typically adjusted, which increases structural complexity and design difficulty.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0028] See also Figure 2As shown, an embodiment of the present application provides a water-cooled plate, comprising: a plate body 1, edge ribs, and a plurality of segmenting ribs 6. The edge ribs are provided on the plate body 1, and the edge ribs include a first rib segment 2, a second rib segment 3, a third rib segment 4, and a fourth rib segment 5. The first rib segment 2, the third rib segment 4, the second rib segment 3, and the fourth rib segment 5 are sequentially arranged to form a closed loop, with adjacent segments vertically connected. Each of the splitting ribs 6 is located inside the edge ribs. Each of the splitting ribs 6 is sequentially arranged along the length of the first rib segment 2 and extends perpendicularly to the first rib segment 2. One of two adjacent splitting ribs 6 is connected to the first rib segment 2, and the other is connected to the second rib segment 3. A flow channel is formed between the third rib segment 4, the fourth rib segment 5, and each of the adjacent splitting ribs 6. Each flow channel is sequentially connected. Each group of diverter ribs 7 is disposed within a corresponding flow channel. The distance between the splitting rib 6 and the corresponding first rib segment 2 or second rib segment 3 between at least some of the adjacent flow channels is greater than the distance between the diverter rib 7 and the corresponding first rib segment 2 or second rib segment 3 within the flow channel. A diverter channel is formed between each of the splitting ribs 6 and the adjacent diverter ribs 7. In the embodiment of the present application, by improving the length of at least part of the dividing rib 6, that is, by increasing the distance between the dividing rib 6 and the first baffle section 2 or the second baffle section 3, it is possible to increase the fluid flow rate in the first diversion channel of the downstream flow channel of the two adjacent flow channels, thereby facilitating the uniform distribution of the cooling medium in each diversion channel in the entire water-cooled plate, improving the uniformity of the flow rate of each diversion channel, and thereby improving the temperature uniformity of the battery cells on the upper part of the water-cooled plate.

[0029] At least on the side where the water flows into the partial flow channel, the distance between the diverter rib 7 of the flow channel close to the upstream and the corresponding first baffle rib segment 2 or second baffle rib segment 3 is greater than the distance between the diverter rib 7 of the flow channel far from the upstream and the corresponding first baffle rib segment 2 or second baffle rib segment 3, such as Figure 2 As shown in the second and third flow channels in FIG. Thus, on the side where the fluid flows in, the fluid is evenly distributed in each branch channel in the same flow channel.

[0030] Optionally, at least on one side of the flow channel where the water flows out (e.g. Figure 2 (As shown in the second and third flow channels in FIG), the distance between the diverter rib 7 closest to the upstream flow channel and the corresponding first baffle rib segment 2 or second baffle rib segment 3 is shorter than the distance between the diverter rib 7 in the flow channel farther from the upstream and the corresponding first baffle rib segment 2 or second baffle rib segment 3. By extending the length of the diverter rib 7 closest to the upstream flow channel on the water outflow side, the fluid in the first diverter channel within that flow channel can flow into the first diverter channel in the downstream flow channel, thereby promoting uniform distribution of the fluid in the next flow channel.

[0031] Optionally, a water inlet 8 is provided on the plate body 1. The water inlet 8 can be located between each diverter rib 7 and the first baffle segment 2 in the flow channel at the end. The distance between the diverter rib 7 closest to the water inlet 8 and the corresponding first baffle segment 2 is smaller than the distance between the diverter rib 7 and the first baffle segment 2 farther from the water inlet 8. By extending the length of the diverter rib 7 closest to the water inlet 8, the flow rate in the diverter channel corresponding to the diverter rib 7 can be reduced, thereby facilitating uniform distribution of the fluid.

[0032] In some possible implementations, the distances between each diverter rib 7 and the second baffle rib segment 3 in the flow channel connected to the water inlet 8 are equal. The plate body 1 has a water outlet 9, which can be located between each diverter rib 7 and the first baffle rib segment 2 in the flow channel at the other end. The water outlet 9 is located near the upstream flow channel of the current flow channel, and the ends of each diverter rib 7 in the flow channel connected to the water outlet 9 are flush. By positioning the water outlet 9, the fluid can be relatively evenly distributed on the water inlet side without increasing the length of each diverter rib 7.

[0033] It should be noted that the plate body can be divided into an upper plate body and a lower plate body, and the edge retaining ribs, dividing ribs and diverter ribs are all arranged between the two plate bodies to form a diverter channel inside.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
