Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plates, specifically a liquid cooling plate heat dissipation structure. Background Technology

[0002] A liquid cooling plate is a device used for heat dissipation, typically applied in high-performance computers, servers, and other applications requiring massive computation and data processing. It lowers the chip temperature by introducing water or other liquids into the heat sink and using the fluid to cool the silicon wafer. A liquid cooling plate usually consists of a metal base and many tiny pipes filled with water or other highly thermally conductive liquids. When electronic components generate excessive heat, these pipes absorb it and transfer it to water molecules in the surrounding environment. After circulation, the excess heat is carried away and the liquid re-enters the system to maintain a stable temperature.

[0003] Existing technologies for liquid cooling plate heat dissipation structures still have certain shortcomings in use. Traditional liquid cooling plate heat dissipation structures usually have the pipes and plate base as an integrated structure. When the liquid circulates in the pipes for a long time, scale will form inside, which will reduce the flow space of the pipes, reduce the heat dissipation speed, and require the replacement of the liquid cooling plate. This is inconvenient for later maintenance and results in high costs. Utility Model Content

[0004] The purpose of this utility model is to provide a liquid cooling plate heat dissipation structure to solve the problems mentioned in the background art. In traditional liquid cooling plate heat dissipation structures, the pipes and plate base are usually designed as an integrated structure. When the liquid circulates in the pipes for a long time, scale will form inside, which will reduce the flow space of the pipes, reduce the heat dissipation speed, require replacement of the liquid cooling plate, which is inconvenient for later maintenance and has a high cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid-cooled plate heat dissipation structure, including a liquid-cooled plate base, the liquid-cooled plate base having a disassembly groove inside, the disassembly groove having a serpentine heat dissipation pipe inside, the serpentine heat dissipation pipe being disposed inside a copper fixed frame, the liquid-cooled plate base having a cold water circulation chamber and a hot water circulation chamber on both sides respectively, the cold water circulation chamber having a cold water inlet at one end, the hot water circulation chamber having a hot water outlet at one end, the liquid-cooled plate base having a plate cover at the top, the interior of the cold water circulation chamber having a second fixing bolt at one end, and the interior of the hot water circulation chamber having a first fixing bolt at the other end.

[0006] In a further embodiment, the top of the plate cover and the liquid cooling plate base are connected by a fixed protrusion and a fixed recess, and the rear end of the plate cover and the liquid cooling plate base are fixedly connected by a locking insert block and a locking insert groove, and the locking insert block and the locking insert groove are both designed with a cross-shaped structure.

[0007] In a further embodiment, one end of the serpentine heat dissipation pipe is fixedly connected to the cold water circulation chamber via a first assembly clip and a first combination slot, and the first assembly clip and the first combination slot are fixedly connected via a second fixing bolt.

[0008] In a further embodiment, the other end of the serpentine heat dissipation pipe is fixedly connected to the hot water circulation chamber via a second assembly clip and a second assembly slot, and the second assembly clip and the second assembly slot are fixedly connected via a first fixing bolt.

[0009] In a further embodiment, both sides of the first fixing bolt and the second fixing bolt are provided with through holes, and the top of the first fixing bolt and the second fixing bolt are provided with sealing rings, and the sealing rings are glued to the first fixing bolt and the second fixing bolt.

[0010] In a further embodiment, the copper molded frame and the serpentine heat dissipation pipe are connected by welding, and the two ends of the serpentine heat dissipation pipe and the disassembly groove are connected by positioning strips.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this utility model, the serpentine heat dissipation pipe is designed as a detachable structure. When the inside of the pipe is blocked, it can be directly removed to flush and clear the blockage inside the U-shaped heat dissipation pipe, making the liquid flow more smoothly and extending the service life of the U-shaped heat dissipation pipe. This not only saves costs but also effectively maintains the heat dissipation speed. The disassembly and assembly principle is simple and easy to maintain later. Attached Figure Description
