Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy heat dissipation technology, specifically relating to an aluminum alloy heat dissipation structure for a liquid-cooled energy storage system. Background Technology

[0002] Liquid-cooled energy storage systems mainly consist of key components such as coolant circulation pumps, radiators, cooling pipes, temperature sensors, and control systems. During system operation, the coolant circulation pump delivers coolant to the cooling pipes inside the energy storage device, which are in close proximity to heat-generating components such as batteries. When the battery charges and discharges, the heat is rapidly transferred to the coolant, causing the coolant to absorb heat and its temperature to rise. The heated coolant is then pumped to the radiator, where it exchanges heat with the outside air or other cooling media, releasing the heat. After its temperature decreases, the coolant returns to the energy storage device to continue the heat absorption and circulation process. Compared to traditional air-cooled methods, liquid-cooled energy storage systems offer significant technological advantages.

[0003] Existing liquid-cooled energy storage system radiators ensure heat dissipation performance by adding fins. The fins are usually made of materials with a thickness of about 0.5 mm. After a period of use, the heat dissipation effect of the fins often decreases due to blockage by foreign objects and dust accumulation. Since the fins are set relatively long along the length of the radiator, they are prone to collapsing or sticking together when cleaned with a high-pressure air gun, which affects the heat dissipation effect in subsequent use.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides an aluminum alloy heat dissipation structure for a liquid-cooled energy storage system. The structure includes an aluminum alloy body, two heat dissipation ribs are fixedly connected to the left and right sides of the upper surface of the aluminum alloy body, and extension blocks are fixedly connected to the sides of the tops of the two heat dissipation ribs that are close to each other. Multiple heat dissipation fins are fixedly connected to the middle of the upper surface of the aluminum alloy body, and a fixing rod is installed between the extension blocks on the left and right sides. Multiple partitions are fixedly connected to the lower surface of the fixing rod, and the partitions are located between two adjacent heat dissipation fins.

[0008] Preferably, the upper surface of the extension block is provided with an elongated groove, the middle of which is provided with a threaded groove.

[0024] This specific embodiment is an aluminum alloy heat dissipation structure for a liquid-cooled energy storage system, and its structural schematic diagram is shown below. Figures 1-6 As shown, the structure includes an aluminum alloy body 1. Two heat dissipation ribs 2 are fixedly connected to the left and right sides of the upper surface of the aluminum alloy body 1. An extension block 3 is fixedly connected to the side where the tops of the two heat dissipation ribs 2 are close to each other. Multiple heat dissipation fins 4 are fixedly connected to the middle of the upper surface of the aluminum alloy body 1. A fixing rod 5 is installed between the extension blocks 3 on the left and right sides. Multiple partitions 6 are fixedly connected to the lower surface of the fixing rod 5. The partitions 6 are located between two adjacent heat dissipation fins 4.

[0025] By setting multiple heat dissipation fins 4 on the aluminum alloy body 1, with the bottom end of the heat dissipation fins 4 fixed to the main body 101 of the aluminum alloy body 1 and the top end of the heat dissipation fins 4 provided with fixing rods 5 and partitions 6, this structure allows the heat dissipation fins 4 to be completely separated, which not only increases the contact area with air and accelerates the heat dissipation, but also makes it easy to clean with a high-pressure air gun, preventing the fins from collapsing or sticking together, and making them less prone to clogging, thus improving the heat dissipation effect during use.

[0026] like Figure 3-6 As shown: In this embodiment, the upper surface of the extension block 3 is provided with a long groove 301, the middle part of the long groove 301 is provided with a threaded groove 302, one end of the fixing rod 5 is located inside the long groove 301, and a fixing screw 303 is threadedly connected inside the threaded groove 302. The bottom end of the fixing screw 303 is pressed against the upper surface of the fixing rod 5.

[0027] During installation, both ends of the fixing rod 5 are placed into the long slot 301. At this time, the partition 6 on the lower surface of the fixing rod 5 is inserted between two adjacent heat dissipation fins 4. The partition 6 supports the two adjacent heat dissipation fins 4, so that the heat dissipation fins 4 can be completely separated.

[0028] like Figure 1 and Figure 2 As shown: In this embodiment, there are multiple fixing rods 5, which are evenly distributed along the length of the aluminum alloy body 1; thus, when the length of the aluminum alloy body 1 is long, it can be supported by multiple fixing rods 5.

[0029] like Figure 3 and Figure 4 As shown: In this embodiment, the bottom end of the partition 6 is a conical structure, and the width between the partition 6 and the two adjacent heat dissipation fins 4 is the same; the aluminum alloy body 1, heat dissipation ribs 2, extension blocks 3 and heat dissipation fins 4 are integrally formed, and the fixing rod 5 and the partition 6 are integrally formed; Since the bottom end of the partition 6 is a conical structure, the partition 6 on the lower surface of the fixing rod 5 can be more easily inserted between the two adjacent heat dissipation fins 4 for good separation and support, which is convenient for cleaning with a high-pressure air gun and will not cause the fins to collapse or stick together.

[0030] like Figure 3 As shown: In this embodiment, the aluminum alloy body 1 includes a rectangular main body 101, on which a plurality of heat dissipation through holes 102 are provided. The heat dissipation through holes 102 are rectangular in structure, and the six heat dissipation through holes 102 are the same size, which facilitates the processing of the heat dissipation through holes 102. The upper and lower inner walls of the heat dissipation through holes 102 are corrugated heat-conducting surfaces and have a plurality of heat-conducting teeth 103. The heat-conducting teeth 103 are arc-shaped and are evenly distributed along the upper and lower inner walls of the heat dissipation through holes 102. The coolant after heat absorption can flow in the heat dissipation through holes 102, and by contacting the corrugated heat-conducting surfaces, the contact area with the aluminum alloy body 1 is increased, thereby better absorbing heat and enabling the aluminum alloy body 1 to dissipate heat to the outside more quickly through the heat dissipation fins 2, thus improving the heat dissipation effect of the aluminum alloy heat dissipation structure.

[0031] like Figure 3 and Figure 5 As shown: In this embodiment, there are six heat dissipation through holes 102, forming a first connecting rib 201, a second connecting rib 202, a third connecting rib 203, a fourth connecting rib 204, a fifth connecting rib 205, a sixth connecting rib 206, and a seventh connecting rib 207. The first connecting rib 201 and the seventh connecting rib 207 have the same width, and the second connecting rib 202, the third connecting rib 203, the fifth connecting rib 205, and the sixth connecting rib 206 have the same width. The width of the first connecting rib 201 and the fourth connecting rib 204 is greater than the width of the second connecting rib 202, and the width of the first connecting rib 201 is less than the width of the fourth connecting rib 204.

[0032] By setting heat dissipation holes 102 and multiple connecting ribs, not only is the overall weight reduced, but the structural strength of the aluminum alloy body 1 is also preserved, making it less prone to deformation under pressure. The fourth connecting rib 204 and the connecting ribs on both sides are wider, resulting in better central stability.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
