[0002] Currently, liquid cooling technology can effectively dissipate heat from high-power electronic components. However, the liquid cooling plates used in existing liquid cooling technologies can only adapt to electronic components with uniformly distributed heat sources. Furthermore, the flow rate within the liquid cooling plate channels tends to be uniform, and it cannot adjust the flow rate within the liquid cooling plate channels according to the non-uniform layout of heat sources and differences in power consumption to meet heat dissipation requirements. Ultimately, this causes the operating temperature of electronic components to deviate from the reasonable range, affecting the service life of electronic devices. Patent publication number CN116315266A discloses a battery pack liquid cooling system, a battery pack, and a flow distribution control method. Specifically, it discloses that the liquid cooling plate has an inlet and an outlet nozzle connected to the cooling channels, and the inlet nozzle has a flow adjustment component that is communicatively connected to the battery management system.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figure 1-6This utility model provides a technical solution: an adjustable flow resistance liquid cooling plate, comprising a flow channel 101 inside the liquid cooling plate body 1, wherein the top surface of the liquid cooling plate body 1 has inlet and outlet ports 102 connected to the inlet and outlet of the corresponding flow channel 101, and a flow resistance adjustment component 2 is fixedly provided at the bottom of the flow channel 101 at the position corresponding to the inlet and outlet ports 102; the flow resistance adjustment component 2 includes a guide block 21 and at least one pad 22, the guide block 21 has a conical structure, the bottom end of the guide block 21 is provided with a stud 211, and the top end of the pad 22 is provided with a stud 211. The flow guide block 21 has a matching screw hole 221, and the stud 211 of the flow guide block 21 is threadedly connected to the screw hole 221 of the pad block 22. The bottom end of the pad block 22 is provided with a stud 222 with the same structure as the stud 211. The bottom end of the flow channel 101 is provided with a screw hole 103 at the position corresponding to the liquid inlet / outlet 102. The screw hole 103 has the same structure as the screw hole 221. The pad block 22 at the bottom end of the flow resistance adjustment assembly 2 is threadedly connected to the screw hole 103 of the liquid cooling plate body 1 through its stud 222. The flow guide block 21 and the pad block 22 are coaxially arranged with their corresponding liquid inlet / outlet 102.

[0018] Working principle:

[0019] The flow guide block 21 and the pad 22 of the flow resistance adjustment assembly 2 are all threadedly connected, as are the adjacent pads 22. Therefore, the pads 22 can be individually screwed and disassembled, which means that the number of pads 22 in the flow resistance adjustment assembly 2 can be increased or decreased.

[0020] When the flow resistance of the liquid cooling plate needs to be increased, the pad 22 of the flow resistance adjustment component 2 is added to increase the height of the guide block 21 of the flow resistance adjustment component 2. Since the guide block 21 is a conical structure, the flow area of ​​the inlet and outlet 102 is reduced, thereby increasing the flow resistance and reducing the flow rate.

[0021] When the flow resistance of the liquid cooling plate needs to be reduced, the pad 22 of the flow resistance adjustment component 2 is reduced, so that the height of the guide block 21 of the flow resistance adjustment component 2 is lowered, thereby increasing the flow area of ​​the inlet and outlet 102, reducing the flow resistance and increasing the flow rate.

[0022] Furthermore, the cone head of the flow guide block 21 is provided with a flow guide spherical surface 212, and the pad block 22 is a cylindrical structure; the flow guide spherical surface 212 improves the flow guiding effect of the flow guide block 21 on the liquid.

[0023] Furthermore, the circumferential sidewall of the guide block 21 is provided with a flat surface 213, and the circumferential sidewall of the pad block 22 is provided with a flat surface 223; the flat surface 213 facilitates the screwing and disassembly of the guide block 21, and the flat surface 223 facilitates the screwing and disassembly of the pad block 22.

[0024] The adjustable flow resistance liquid cooling plate disclosed in this embodiment adjusts the flow area of ​​the inlet and outlet 102 by increasing or decreasing the number of pads 22 in the flow resistance adjustment component 2, thereby increasing or decreasing the flow resistance and flow rate. The flow distribution and flow resistance of the liquid cooling plate can be adjusted according to the heat load of different areas, optimizing the temperature distribution and improving the cooling efficiency and energy efficiency of the entire liquid cooling system. The flow guide block 21 and the pad 22, as well as the adjacent pads 22, are all threaded connections, which are simple in structure, low in cost, and easy to disassemble and adjust, and can flexibly adjust the flow resistance of the liquid cooling plate.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
