Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, specifically a deep-drawn VC heat-equalizing finned liquid cooling plate. Background Technology

[0002] In the field of electronic heat dissipation, the surface of a vapor chamber is in contact with the heat source, and the vapor chamber is filled with a working medium. The working medium near the heat source absorbs heat and evaporates, while the gaseous working medium flows to the cold end away from the heat source, releases heat, and condenses into a liquid medium, thus achieving the purpose of cooling the heat source. Cold-end heat dissipation typically involves arranging heat dissipation fins on the surface of the vapor chamber's cold end. These fins require a relatively large space, and with the increasing demand for electronic heat dissipation, air-cooled heat dissipation fins are no longer sufficient. Utility Model Content

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] Example

[0019] like Figure 1-5 As shown, a deep-drawn VC heat exchanger finned liquid cooling plate includes a substrate 1. The lower end of the substrate 1 is provided with a liquid cooling upper plate 7, a heat exchanger upper plate 8, and a heat exchanger lower plate 10. The middle of the end face of the substrate 1 is provided with a refrigerant inlet 5 and a refrigerant outlet 6. The end face of the liquid cooling upper plate 7 is provided with a through hole that communicates with the refrigerant inlet 5 and the refrigerant outlet 6. The end face of the heat exchanger upper plate 8 is stamped with a plurality of protrusions 9 and staggered toothed fins 11.

[0020] In this embodiment, at least four clips 2 are symmetrically provided at both ends of the substrate 1 to fix the overall liquid cooling plate.

[0021] Multiple protrusions 9 are arranged horizontally, and multiple staggered toothed fins 11 are respectively arranged between multiple protrusions 9.

[0022] The heat exchange plate 8 has a coolant inlet 13 and a coolant outlet 14 in the middle.

[0023] The heat spreader plate 8 and the liquid cooling plate plate 7 are brazed to form an integral structure.

[0024] The integrated heat exchange plate 8 and the liquid cooling plate 7 are embedded at the bottom of the substrate 1.

[0025] The vapor chamber plate has several stamped protrusions, with staggered toothed fins arranged between them. A liquid cooling channel is formed between the vapor chamber plate and the liquid cooling plate. Coolant flows from the inlet into the staggered toothed fins on both sides, then flows back into the staggered toothed fins through the loops on both sides of the liquid cooling channel, and finally flows out from the coolant outlet, thereby carrying away the heat generated by the heat source. The vapor chamber plate and the liquid cooling plate are brazed together and embedded in the bottom of the substrate. The liquid inlet and outlet protrude from the through holes in the substrate.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
