Description

Technical Field

[0001] This utility model relates to the field of aluminum plates, specifically to an aluminum plate for a segmented liquid cooling radiator. Background Technology

[0002] In fields such as electronic equipment and new energy vehicles, with the continuous increase in power density, the heat generated during equipment operation has increased significantly. Liquid cooling radiators are widely used as efficient heat dissipation components. Existing liquid cooling radiators mostly use aluminum plates with an integrated structure or a simple segmented design. Their cooling principle is mainly based on the flow of coolant in a single channel, using the thermal conductivity of the metal plate to carry away the heat.

[0003] In existing technologies, the liquid inlet section of liquid-cooled radiators often adopts a straight-channel design, where the coolant flows directly from the inlet to the outlet, which can easily lead to uneven liquid distribution, excessively fast or slow flow rates in some areas, and affect heat dissipation efficiency. The heat exchange section often adopts a single straight pipe or serpentine pipe structure, which has a limited heat exchange area between pipes and a single heat transfer path, making it difficult to quickly disperse and dissipate concentrated heat, resulting in local overheating. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies by providing an aluminum plate for a segmented liquid-cooled radiator. This plate features an inclined guide channel on the liquid inlet plate and a honeycomb heat pipe assembly on the heat exchange plate, thus solving the technical problems of uneven coolant distribution, low heat exchange efficiency, inability to recover waste heat, and poor overall heat dissipation performance in the prior art.

[0005] The objective of this utility model is achieved through the following means:

[0006] An aluminum plate for a segmented liquid-cooled radiator includes an inlet plate, a heat exchange plate, and a waste heat recovery plate. The inlet plate and the heat exchange plate are connected by a first outlet pipe, and the waste heat recovery plate is connected to the heat exchange plate by two second outlet pipes. An inlet pipe is fixed to the upper left side of the inlet plate, and the first outlet pipe is located at the lower right side of the inlet plate. The inlet plate has oblique flow channels on both its front and rear sides, with the two ends of each channel connected to the first outlet pipe and the inlet pipe, respectively. A honeycomb heat-conducting pipe assembly is installed inside the heat exchange plate. The honeycomb heat-conducting pipe assembly includes longitudinally equidistant honeycomb heat-conducting pipes, which are composed of alternating honeycomb pipes. A thick cavity is formed on the side of the waste heat recovery plate closest to the second outlet pipe, and a flat cavity is formed on the other side. A third outlet pipe is installed at the output end of the waste heat recovery plate.

[0007] Furthermore, corrugated strips are provided on both the front and rear sides of the inlet plate, and the corrugated strips are integrally formed with the inlet plate, which increases the contact area between the coolant and the inlet plate.

[0008] Furthermore, the liquid inlet plate is provided with first heat-conducting fins on both the front and rear sides, and the first heat-conducting fins are fixedly connected to the liquid inlet plate, thereby improving the heat exchange capacity of the liquid inlet plate.

[0009] Furthermore, the heat exchange plate is provided with second heat-conducting fins on both the front and rear sides, and the second heat-conducting fins are fixedly connected to the heat exchange plate, thereby improving the heat exchange capacity of the heat exchange plate.

[0010] Furthermore, the waste heat recovery plate is provided with third heat-conducting fins on both the front and rear sides, and the third heat-conducting fins are fixedly connected to the waste heat recovery plate, thereby improving the heat exchange capacity of the waste heat recovery plate.

[0011] Furthermore, the waste heat recovery plate has a nano-oxide layer on both the front and rear sides inside, and the nano-oxide layer is fixed to the waste heat recovery plate. The nano-oxide layer enhances convective heat transfer and further recovers the waste heat in the coolant.

[0012] The beneficial effects of this utility model are:

[0013] The inlet plate uses an inclined guide channel to ensure uniform flow of coolant from the inlet pipe to the first outlet pipe, reducing flow resistance and solving the problem of uneven liquid distribution in existing inlet structures. The honeycomb heat-conducting pipe group of the heat exchange plate is composed of alternating honeycomb pipes, increasing the heat exchange area and heat conduction path, improving heat exchange efficiency, and solving the problems of small heat dissipation area and local overheating in traditional heat exchange pipes. The waste heat recovery plate uses a thick cavity and a flat cavity design to effectively collect waste heat from the coolant, which is then output and recycled through the third outlet pipe, solving the problem of waste heat in existing radiators. The overall segmented structure improves the comprehensive performance of heat dissipation and waste heat recovery through the coordinated work of each section, offering the benefits of high efficiency and energy saving.

Figures 1-3 The present invention relates to a segmented liquid-cooled radiator aluminum plate, comprising an inlet plate 1, a heat exchange plate 2, and a waste heat recovery plate 3. The inlet plate 1 and the heat exchange plate 2 are connected by a first outlet pipe 5, and the waste heat recovery plate 3 is connected to the heat exchange plate 2 by two second outlet pipes 6. An inlet pipe 4 is fixed on the upper left side of the inlet plate 1, and the first outlet pipe 5 is located on the lower right side of the inlet plate 1. The inlet plate 1 has inclined guide grooves 8 on both the front and rear sides, and the two ends of the inclined guide grooves 8 are connected to the first outlet pipe 5 and the inlet pipe 4, respectively. A honeycomb heat conduction pipe group 10 is installed inside the heat exchange plate 2. The honeycomb heat conduction pipe group 10 includes honeycomb heat conduction pipes 16 that are equidistantly distributed longitudinally. The honeycomb heat conduction pipes 16 are composed of honeycomb pipes that are alternately distributed and connected. A thick cavity 11 is opened on the side of the waste heat recovery plate 3 near the second outlet pipe 6, and a flat cavity 12 is opened on the other side of the waste heat recovery plate 3. A third outlet pipe 7 is installed at the output end of the waste heat recovery plate 3.

[0019] like Figure 2 As shown, corrugated strips 9 are provided on both the front and rear sides of the inlet plate 1, and the corrugated strips 9 are integrally formed with the inlet plate 1. The corrugated strips 9 increase the contact area between the coolant and the inlet plate 1.

[0020] like Figure 1 and Figure 2 As shown, the front and rear sides of the liquid inlet plate 1 are provided with first heat-conducting fins 13, and the first heat-conducting fins 13 are fixedly connected to the liquid inlet plate 1.

The corrugated strips 9 in the inlet plate 1 increase the contact area of ​​the coolant, and the external first heat-conducting fins 13 enhance heat exchange and improve the initial heat dissipation effect. The coolant enters the heat exchange plate 2 through the first outlet pipe 5 and flows through the honeycomb heat-conducting pipe group 10.

Subsequently, the coolant enters the waste heat recovery plate 3 through the upper and lower second outlet pipes 6, first flowing through the thick cavity 11 and then through the flat cavity 12. The internal nano-oxide layer 17 enhances convective heat transfer, and the external third heat-conducting fins 15 further recover waste heat.
