Description

Technical Field

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

[0002] With the increasing power consumption of electronic devices, the application of liquid cooling plates is becoming more and more widespread. However, existing liquid cooling plates still have the following problems in use: First, the circulation efficiency of the flow guiding structure is low, and the flow of heat transfer fluid is not smooth, resulting in heat that cannot be quickly dissipated and the heat dissipation effect is limited; Second, the compatibility of heat exchange components is insufficient, and the heat exchange between the fins and the heat conduction plate and fan is not sufficient, which easily leads to local overheating. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a heat dissipation liquid cooling plate with a flow guiding structure, which is equipped with a high-efficiency flow guiding copper flow guiding pipe assembly and a fin and fan structure for synergistic heat dissipation, thus solving the problems of low heat dissipation efficiency and insufficient heat exchange mentioned in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a heat dissipation liquid cooling plate with a flow guiding structure, comprising a shell assembly, wherein an active heat dissipation assembly and a flow guiding assembly are disposed on the shell assembly.

[0005] The outer casing assembly includes an outer casing. Multiple pipe assembly slots are provided at both ends of the inner wall of the outer casing for limiting and assembling the guide pipes, thus improving structural stability. Additionally, multiple pipe penetration slots are provided at both ends of the inner wall of the outer casing, corresponding to the multiple pipe assembly slots on their respective sides, for the guide pipes to pass through, ensuring the integrity of the flow path. A heat-conducting copper plate is fixedly connected to the bottom of the outer casing for quickly absorbing heat from the components to be cooled, providing a foundation for heat dissipation.

[0006] The active heat dissipation component includes a fan mount, which is fixedly connected to the top of the inner side of the outer casing. Two cooling fans are symmetrically installed inside the fan mount, which can generate strong airflow to accelerate heat exchange. The top of the fan mount is flush with the top of the outer casing to ensure the flatness of the structure.

[0007] The flow guiding assembly includes a circulation pump, which is fixedly installed at the center of the front end of the outer casing to provide power for the circulation of the heat-conducting liquid. A flow guiding pipe is connected to both the output and input ends of the circulation pump. The flow guiding pipe is assembled in a pipe assembly groove and passes through the groove. The flow guiding pipe is made of copper and filled with heat-conducting liquid. The copper material ensures excellent thermal conductivity, and the heat-conducting liquid achieves efficient heat transfer. Several copper fins are fixedly provided on the outer wall of the flow guiding pipe to increase the heat exchange area. The copper fins are located below the cooling fan and are fixedly welded to the bottom heat-conducting copper plate, achieving synergistic heat exchange of "liquid cooling + air cooling" and improving heat dissipation efficiency.

[0008] As a further improvement of this utility model, the thermally conductive copper plate is connected to the outer shell by bolts, which makes assembly and disassembly convenient. The lower surface of the thermally conductive copper plate is coated with a thermally conductive silicone grease layer to further enhance heat conduction.

[0009] As a further improvement of this utility model, the cooling fan and the fan base are installed by a snap-fit ​​connection, which facilitates maintenance and replacement, and the outer wall of the cooling fan is fitted with a shock-absorbing rubber ring to reduce operating noise and vibration.

[0010] As a further improvement of this utility model: the copper fins are distributed in an array on the outer wall of the guide tube, with a large and uniform heat exchange area, and the copper fins are connected to the guide tube by reflow welding, which is a firm connection with minimal thermal conductivity loss.

[0011] As a further improvement of this utility model: a mounting base is fixedly connected to one end of the outer side wall of the outer shell, and an oblong hole is provided between the upper and lower side walls of the mounting base to facilitate the installation and fixation of the device and adapt to different installation scenarios; a wear-resistant metal sleeve is provided on the inner wall of the oblong hole to improve the durability of the installation structure.

[0012] As a further improvement of this utility model: the outer shell is made of aluminum alloy, which is lightweight and has a certain thermal conductivity, and the outer surface of the outer shell is anodized to improve its corrosion and rust resistance.

[0013] As a further improvement of this utility model, the heat-conducting liquid filled in the guide tube is a water-based coolant with a large heat capacity and good heat conduction effect. In addition, sealing rubber gaskets are provided at both ends of the guide tube to ensure the sealing of the circulation system and prevent leakage of the heat-conducting liquid.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a circulating pump drives the flow of the heat-conducting liquid inside the copper guide tube, which, together with copper fins, forms a highly efficient liquid cooling circulation and heat exchange structure. This significantly improves the circulation efficiency of the heat-conducting liquid, accelerates heat conduction and dissipation, and effectively solves the problem of low heat dissipation efficiency.

[0015] In this invention, the cooling fan of the active heat dissipation component works in synergy with the copper fins and the thermally conductive copper plate to achieve a composite heat dissipation of "liquid cooling + air cooling", which enhances the sufficiency of heat exchange, avoids local overheating, and further improves the overall heat dissipation performance.

[0024] The flow guiding component 3 includes a circulation pump 31, which is fixedly installed on the outer front end of the outer casing 11 to provide power for the circulation of the heat-conducting liquid. The output and input ends of the circulation pump 31 are each connected to a flow guiding pipe 32.

The heat of the electronic component is quickly conducted through the heat-conducting copper plate 16 to the copper fins 33 and the heat-conducting liquid in the guide tube 32. The circulating pump 31 drives the heat-conducting liquid to circulate in the guide tube 32, carrying the heat to the copper fins 33. At the same time, the cooling fan 22 is started to generate airflow, which accelerates the heat exchange between the copper fins 33 and the outside world, thereby realizing the efficient composite heat dissipation of "liquid cooling heat absorption + air cooling heat dissipation", quickly dissipating the heat of the electronic component and ensuring that it operates within a safe temperature range.
