Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy heat dissipation technology, and specifically relates to an aluminum alloy heat dissipation structure for a liquid cooling heat dissipation device in an energy storage system. Background Technology

[0002] During the charging and discharging process, the battery temperature of an energy storage system will rise. Using it under continuous high-temperature conditions will greatly shorten the battery life and may also cause safety problems such as thermal runaway. In order to improve the problem of thermal runaway, liquid cooling technology is often used to dissipate heat from the battery. Liquid cooling technology is a way to dissipate heat directly through liquid convection, combined with a heat dissipation substrate, to achieve precise temperature control of the battery, ensure uniform cooling, and thus ensure the stable operation of the energy storage battery.

[0003] Existing heat dissipation substrates are mostly made of aluminum alloy, brass or bronze in the form of plates or sheets. During heat dissipation, the heat carried by the coolant is conducted to the heat dissipation substrate and then dissipated into the surrounding air. Because the heat absorption area of ​​the heat dissipation substrate is not large enough, the heat conversion efficiency is not efficient enough, and it is difficult to dissipate heat from the coolant quickly. To address this, we propose an aluminum alloy heat dissipation structure for a liquid cooling heat dissipation device in an energy storage system. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aluminum alloy heat dissipation structure for a liquid cooling heat dissipation device for an energy storage system. This structure aims to solve the problem that when the heat dissipation substrate is used for heat dissipation, the heat carried by the coolant cannot be effectively transferred to the heat dissipation substrate, resulting in insufficient heat conversion efficiency and difficulty in quickly dissipating heat from the coolant.

[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 cooling heat dissipation device of an energy storage system. The structure includes an aluminum alloy heat dissipation body, the cross-section of which includes a rectangular main body. Multiple heat dissipation through holes are provided on the main body. The inner walls of the upper and lower sides of the heat dissipation through holes are corrugated heat-conducting surfaces and have multiple heat-conducting teeth. Two heat dissipation ribs are fixedly connected to the left and right sides of the upper surface of the main body. An extension block is fixedly connected to the side where the tops of the two heat dissipation ribs are close to each other.

[0008] Preferably, the number of heat dissipation through holes is six, forming a first connecting rib, a second connecting rib, a third connecting rib, a fourth connecting rib, a fifth connecting rib, a sixth connecting rib, and a seventh connecting rib. The first connecting rib and the seventh connecting rib have the same width, the second connecting rib, the third connecting rib, the fifth connecting rib, and the sixth connecting rib have the same width, the width of the first connecting rib and the fourth connecting rib are both greater than the width of the second connecting rib, and the width of the first connecting rib is less than the width of the fourth connecting rib.

[0009] Furthermore, the heat dissipation holes are rectangular in shape, and all six holes are the same size.

[0010] Furthermore, the heat-conducting teeth have an arc-shaped structure, with multiple heat-conducting teeth evenly distributed along the upper and lower inner walls of the heat dissipation through holes.

[0011] Furthermore, the heat dissipation fins are set perpendicular to the main body and flush with the side of the main body.

[0012] Furthermore, the width of the heat dissipation rib is smaller than the width of the first connecting rib, and the extension block is located on the lower side of the upper surface of the heat dissipation rib and has a protrusion.

[0013] Furthermore, the width of the aluminum alloy heat dissipation body cross section is 139.5-140.5mm, and the main body, heat dissipation through holes, heat conduction teeth, heat dissipation fins and extension blocks are integrally formed.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention reduces the overall weight by creating multiple heat dissipation holes on the main body of the aluminum alloy heat dissipation body, with connecting ribs between the holes. This maintains the structural strength of the aluminum alloy heat dissipation body and prevents deformation under pressure. Furthermore, the inner walls of the upper and lower sides of the heat dissipation holes are provided with multiple heat-conducting teeth forming a corrugated heat-conducting surface. This increases the contact area between the coolant and the aluminum alloy heat dissipation body after heat absorption, allowing the aluminum alloy heat dissipation body to dissipate heat to the outside more quickly through the heat dissipation ribs, thus improving the heat dissipation effect of the aluminum alloy heat dissipation structure.

[0022] This specific embodiment is an aluminum alloy heat dissipation structure for a liquid cooling heat dissipation device in an energy storage system, and its structural schematic diagram is shown below. Figures 1-4 As shown, the structure includes an aluminum alloy heat dissipation body 1. The cross-section of the aluminum alloy heat dissipation body 1 includes a rectangular body part 2. Multiple heat dissipation through holes 3 are provided on the body part 2. The inner walls of the upper and lower sides of the heat dissipation through holes 3 are corrugated heat-conducting surfaces and multiple heat-conducting teeth 4 are formed. Two heat dissipation ribs 5 are fixedly connected to the left and right sides of the upper surface of the body part 2. An extension block 6 is fixedly connected to the side where the tops of the two heat dissipation ribs 5 are close to each other.

[0023] After absorbing heat, the coolant can flow in the heat dissipation holes 3, and increase the contact area with the aluminum alloy heat dissipation body 1 by contacting the corrugated heat-conducting surface, so as to better absorb heat and enable the aluminum alloy heat dissipation body 1 to dissipate heat to the outside more quickly through the heat dissipation fins 5.

[0024] like Figure 1 and Figure 3 As shown: In this embodiment, there are six heat dissipation through holes 3, forming a first connecting rib 301, a second connecting rib 302, a third connecting rib 303, a fourth connecting rib 304, a fifth connecting rib 305, a sixth connecting rib 306, and a seventh connecting rib 307. The first connecting rib 301 and the seventh connecting rib 307 have the same width, and the second connecting rib 302, the third connecting rib 303, the fifth connecting rib 305, and the sixth connecting rib 306 have the same width. The width of the first connecting rib 301 and the fourth connecting rib 304 is greater than the width of the second connecting rib 302, and the width of the first connecting rib 301 is less than the width of the fourth connecting rib 304. By setting heat dissipation through holes 3 and multiple connecting ribs, not only is the overall weight reduced, but the structural strength of the aluminum alloy heat dissipation body 1 is also maintained, making it less prone to deformation under pressure. The fourth connecting rib 304 and the connecting ribs on both sides have a wider width, resulting in better central stability.

[0025] like Figure 1 and Figure 2 As shown: In this embodiment, the heat dissipation through hole 3 is a rectangular structure, and the six heat dissipation through holes 3 are the same size; this makes it convenient to process the heat dissipation through hole 3.

[0026] like Figure 3 and Figure 4 As shown: In this embodiment, the heat-conducting teeth 4 are arc-shaped structures, and multiple heat-conducting teeth 4 are evenly distributed along the upper and lower inner walls of the heat dissipation through hole 3; the multiple heat-conducting teeth 4 can increase the area of ​​the upper and lower inner walls of the heat dissipation through hole 3, and increase the contact area with the aluminum alloy heat dissipation body 1 when the coolant flows, so as to better transfer heat to the aluminum alloy heat dissipation body 1.

[0027] like Figure 1 and Figure 2 As shown: In this embodiment, the heat dissipation rib 5 is arranged perpendicularly to the main body 2, and the heat dissipation rib 5 is flush with the side of the main body 2; thus, the heat dissipation rib 5 and the main body 2 are easy to process.

[0028] like Figure 3 and Figure 4 As shown: In this embodiment, the width of the heat dissipation rib 5 is smaller than the width of the first connecting rib 301. The extension block 6 is located on the lower side of the upper surface of the heat dissipation rib 5 and has a protrusion 601. The top of the heat dissipation rib 5 has a larger contact area with the air, resulting in better heat dissipation. The width of the cross-section of the aluminum alloy heat dissipation body 1 is 139.5-140.5mm. The body 2, heat dissipation through hole 3, heat conduction tooth 4, heat dissipation rib 5 and extension block 6 are integrally formed structures.

[0029] Working principle: By opening multiple heat dissipation holes 3 on the main body 2 of the aluminum alloy heat dissipation body 1, and forming connecting ribs between the multiple heat dissipation holes 3, not only is the overall weight reduced, but the structural strength of the aluminum alloy heat dissipation body 1 is also maintained, making it less prone to deformation under pressure. At the same time, multiple heat-conducting teeth 4 are provided on the inner walls of the upper and lower sides of the heat dissipation holes 3, forming a corrugated heat-conducting surface, which can increase the contact area between the coolant after absorbing heat and the aluminum alloy heat dissipation body 1. This allows the aluminum alloy heat dissipation body 1 to dissipate heat to the outside more quickly through the heat dissipation ribs 5, thereby improving the heat dissipation effect of the aluminum alloy heat dissipation structure.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] 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.
