Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, specifically to a biomimetic flow channel liquid cooling plate with a spider web-like structure. Background Technology

[0002] One of the key components of liquid cooling technology is the liquid cooling plate. The liquid cooling plate is the intermediate place for heat exchange. The heat generated by the chip is conducted to the liquid cooling plate by heat conduction. During the flow of the refrigerant in the water cooling system, convective heat exchange occurs with the side walls of the flow channels, transferring heat from the side walls of the water cooling plate to the refrigerant. The temperature of the refrigerant rises, thereby carrying away the heat.

[0003] Currently, the internal flow channels of water-cooled plates commonly used in servers and communications are serrated channels. The advantage of serrated water-cooled plates is their higher tooth density. Copper serrated teeth are typically 0.15mm thick with a tooth spacing of 0.15mm; aluminum serrated teeth are typically 0.2mm thick with a tooth spacing of 0.2mm. Compared to milled or stamped finned water-cooled plates, serrated water-cooled plates have a higher fin density, resulting in a larger fin area per unit volume and better heat dissipation. However, due to the higher tooth density, the cross-sectional area of ​​the refrigerant flow channel is smaller, leading to greater flow resistance.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a biomimetic flow channel liquid cooling plate with a spider web-like structure is provided to solve the problems of high flow resistance due to the internal shovel tooth structure of traditional water cooling plates, or low flow resistance and low heat dissipation area due to the stamped fin structure.

[0006] To achieve the above objectives, a biomimetic flow channel liquid cooling plate with a spider web-like structure is provided, comprising:

[0007] A flow channel plate has a front and a back. The front of the flow channel plate forms a main flow channel and multiple branch flow channels. The width of the main flow channel gradually increases from the middle of the main flow channel to both ends. Each branch flow channel includes two inclined groove sections and a connecting groove section. One end of each of the two inclined groove sections is connected to both ends of the main flow channel. The inclined groove sections are set at a preset angle to the ends of the main flow channel, and the preset angle is 48° to 55°. The connecting groove section is connected to the other end of the two inclined groove sections. The distance between the two inclined groove sections gradually decreases from one end of the inclined groove section to the other end of the inclined groove section. The inclined groove sections of the multiple branch flow channels gradually increase in length from the middle of the main flow channel to both ends of the main flow channel.

[0008] A cover plate is installed on the front and closes the main flow channel and the multiple branch flow channels. The cover plate has an inlet and an outlet, which are respectively aligned with the two ends of the main flow channel.

[0009] Furthermore, the depth of the main flow channel and the branch flow channel is 0.2–4 mm.

[0010] Furthermore, the cover plate is welded to the front side of the flow channel plate.

[0011] Furthermore, the multiple branch channels are arranged at equal intervals.

[0012] Furthermore, the middle sections of the inclined grooves of the multiple branch channels are connected by connecting groove sections.

[0013] Furthermore, the middle sections of the connecting slots of the multiple branch channels are connected by a connecting slot.

[0014] The beneficial effects of this utility model are that the biomimetic flow channel liquid cooling plate with a spider web-like structure can effectively reduce the problem of high flow resistance of refrigerant in the shovel tooth structure and effectively improve the internal fluid dynamics characteristics of the water cooling plate. At the same time, the biomimetic flow channel liquid cooling plate with a spider web-like structure has a larger coverage density of refrigerant flow channel, more uniform heat source temperature, and lower system thermal resistance compared with traditional flow channels.
