Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling plates, in particular to a liquid cooling plate with a heat dissipation structure. Background Art

[0002] With the development of new energy vehicles and electronic technology, the integration of electronic equipment is getting higher and higher. Not only the heat generated by chips or modules in electronic equipment is getting higher and higher, but the heat dissipation devices of electronic equipment mainly include air-cooled heat dissipation devices and liquid-cooled heat dissipation devices. Due to the high heat capacity and high conductivity of liquid, liquid-cooled heat dissipation devices have stronger heat dissipation capacity than air-cooled heat dissipation devices. Therefore, liquid cooling plates have good heat dissipation performance. However, the existing liquid cooling plate structure is a single plate structure. Although the heat of the heating element is taken away by the opened water channel, on the one hand, the thermal conductivity of the liquid cooling plate itself is poor, and heat transfer cannot be performed well. On the other hand, the contact area with the cooling medium is insufficient, and the heat cannot be taken away quickly, resulting in heat accumulation and low cooling efficiency. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that the existing liquid cooling plate structure is a single plate structure. Although the heat of the heating element is taken away by the opened water channel, on the one hand, the thermal conductivity of the liquid cooling plate itself is poor and the heat transfer cannot be performed well. On the other hand, the contact area with the cooling medium is insufficient and the heat cannot be taken away quickly, which leads to heat accumulation and low cooling efficiency.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: providing a liquid cooling plate with a heat dissipation structure, comprising an aluminum base plate and a cover plate bonded to each other, a groove is provided on the base plate, a heat-conducting copper plate is embedded in the groove, a passage for the circulation of cooling medium is provided in the heat-conducting copper plate, a plurality of heat-conducting sheets are evenly distributed at equal angles in the passage to increase the heat-conducting area; a plurality of heat-conducting columns are fixedly connected to the top surface and the bottom surface of the heat-conducting copper plate, and the heat-conducting columns distributed up and down are respectively embedded in the base plate and the cover plate.

[0005] Furthermore, a liquid inlet hole and a liquid outlet hole connected with the passage are provided on the substrate, and water nozzles are sealedly mounted on the liquid inlet hole and the liquid outlet hole.

[0006] Furthermore, six heat-conducting plates are evenly distributed at equal angles in the straight-line passage in the passage, and a plurality of heat-conducting columns are evenly distributed at equal distances on the top and bottom surfaces of the heat-conducting copper plate.

[0007] Furthermore, a sealing ring for sealing the passage is provided on the inner wall of the groove.

[0008] Furthermore, the height of the heat-conducting copper plate is greater than the depth of the groove, so that the heat-conducting copper plate protrudes out of the groove and is embedded in the cover plate.

[0009] Furthermore, the base plate and the cover plate are attached to each other and fixedly connected by screws.

[0010] Furthermore, the liquid inlet hole and the liquid outlet hole are arranged on the same side of the substrate.

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

[0012] 1. The utility model adopts copper inserts with better thermal conductivity inlaid on the aluminum liquid cooling plate body, and components with large heat generation are arranged on the copper inserts to accelerate heat dissipation. The liquid cooling plate increases the heat conduction area through the heat conducting sheet in the heat conducting copper plate, effectively improves the heat dissipation efficiency, and helps to transfer heat to the cooling medium more quickly; the heat conducting sheets in the passage are evenly distributed, ensuring that the cooling medium flows evenly in the entire heat conducting copper plate, thereby maximizing the heat dissipation effect.

[0013] 2. By providing heat-conducting columns on the upper and lower surfaces of the heat-conducting copper plate, and the heat-conducting columns are respectively embedded in the base plate and the cover plate, the contact area between the heat-conducting copper plate and the base plate and the cover plate is increased, so that the base plate and the cover plate can quickly conduct heat and dissipate heat. In addition, by embedding the heat-conducting columns in the base plate and the cover plate, a stable connection between the various components of the liquid cooling plate is ensured, thereby improving the overall stability and durability of the system.

[0014] 3. The setting of the sealing ring effectively prevents the leakage of the cooling medium, ensures the sealing performance of the liquid cooling plate system, and reduces the risk of system failure; the base plate and the cover plate are fixedly connected by screws, and the liquid inlet and outlet holes are set on the same side of the base plate, making the installation and maintenance of the liquid cooling plate more convenient and reducing the workload of operators.
