Description

Technical Field

[0001] This utility model relates to the field of thermal management technology for new energy batteries, and in particular to a heat sink structure for new energy batteries. Background Technology

[0002] Currently, new energy radiators consist of three types of technical solutions: air cooling, direct cooling, and liquid cooling. Liquid cooling accounts for a relatively high proportion, and most of the liquid cooling structures are harmonica tube structures. The harmonica tube itself cannot achieve coolant diversion and return, so it is necessary to form a flow chamber by adding a manifold and a partition to divert the coolant.

[0003] Traditional harmonica tube radiators have limited coolant flow paths, resulting in insufficient utilization of coolant cooling capacity. Their single-segment structure lacks effective means to ensure proper installation after the separator is inserted into the manifold. While the external welds between the separator and the manifold are good, internal weld quality cannot be checked. When poor welding occurs, the separator fails to divert coolant, allowing it to flow directly into and out of the manifold through the weld defects (channel leakage), failing to flow through the harmonica tube's water chamber as required. This leads to abnormal battery cooling and thermal runaway.

[0004] Therefore, it is necessary to design a heat sink structure for new energy batteries to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing coolant flow paths being short, cooling capacity being underutilized, and the welding yield of separators being undetectable, this utility model provides a new energy battery heat sink structure.

[0006] The technical solution of this utility model is as follows: a new energy battery heat sink structure, including a left collector pipe, a harmonica pipe, a right collector pipe, double partition plates and a plug. The left collector pipe and the right collector pipe are arranged opposite each other. The harmonica pipe is located between the left collector pipe and the right collector pipe, and its two ends are connected to the left collector pipe and the right collector pipe respectively. The left collector pipe and the right collector pipe are provided with four double partition plates along the length direction. The left collector pipe and the right collector pipe are each provided with a groove adapted to the double partition plates. The double partition plates are embedded in the grooves. The four double partition plates divide the interior of the left collector pipe and the right collector pipe into five spaces distributed in sequence. Among them, the three spaces located at both ends and the middle are water chambers, and the two spaces between adjacent water chambers are air chambers. The left collector pipe and the right collector pipe are provided with leakage holes corresponding to the positions of the air chambers. The ends of the left collector pipe and the right collector pipe are provided with plugs, which are sealed to the end openings of the collector pipes.

[0007] To further explain, the double partition plate divides the left manifold into three independent water chambers: the bottom water chamber, the middle water chamber, and the top water chamber. Similarly, the double partition plate divides the right manifold into three independent water chambers: the bottom water chamber, the middle water chamber, and the top water chamber.

[0008] To further explain, the harmonica has four tubes. The fourth tube at the bottom is connected to the bottom water chamber of the right manifold and the bottom water chamber of the left manifold, respectively. The first tube at the top is connected to the top water chamber of the left manifold and the top water chamber of the right manifold, respectively. The second tube is connected to the top water chamber of the right manifold and the middle water chamber of the left manifold, respectively. The third tube is connected to the middle water chamber of the left manifold and the middle water chamber of the right manifold, respectively.

[0009] To further explain, it also includes a manifold, one end of which is connected to the bottom water chamber of the left manifold, and the other end is connected to the top water chamber of the left manifold.

[0010] To further explain, it also includes a single-connector, which is located on the upper side of the middle part of the right manifold, with one end connected to the water chamber at the bottom of the right manifold.

[0011] To further explain, the inlet and outlet pipes include an inlet pipe and an outlet pipe. The inlet pipe is connected to the bottom water chamber of the right manifold via a single connector, and the outlet pipe is connected to the middle water chamber of the right manifold.

[0012] Beneficial effects: 1. This utility model divides the interior of the left and right manifolds into three independent water chambers and two air chambers by four double partition plates, and the air chambers are located between adjacent water chambers to form an isolation, thereby achieving the effect of preventing cross-flow between water chambers and ensuring stable circulation of coolant along a preset path.

[0013] 2. This utility model achieves the effect of timely detection of coolant leakage, rapid interception of unqualified products, and prevention of cooling failure by opening a leakage hole at the corresponding position of the air chamber and cooperating with the sealing structure of the double partition plate when the double partition plate is not sealed properly.

[0014] 3. This utility model extends the flow distance of the coolant in the radiator by designing a cooling circulation path with multiple water chambers, multiple harmonica tubes and manifolds, thereby making full use of the coolant's cooling capacity and improving the cooling efficiency of new energy batteries.

[0021] Example: A heat sink structure for a new energy battery, such as Figures 1-5 As shown, it includes a left manifold 1, a harmonica tube 2, a right manifold 3, double partition plates 6, and a plug 7. The left manifold 1 and the right manifold 3 are arranged opposite each other. The harmonica tube 2 is located between the left manifold 1 and the right manifold 3, and its two ends are connected to the left manifold 1 and the right manifold 3 respectively. The left manifold 1 and the right manifold 3 are respectively provided with four double partition plates 6 along the length direction. The left manifold 1 and the right manifold 3 are each provided with a groove that fits the double partition plate 6. The double partition plate 6 is embedded in the groove. The four double partition plates 6 divide the interior of the left manifold 1 and the right manifold 3 into five spaces distributed in sequence. Among them, the three spaces located at both ends and the middle are water chambers, and the two spaces between adjacent water chambers are air chambers for testing the sealing performance. The left manifold 1 and the right manifold 3 are provided with leakage holes 601 corresponding to the positions of the air chambers. The ends of the left manifold 1 and the right manifold 3 are provided with plugs 7, which are sealed to the openings at the ends of the manifolds.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the double partition plate 6 divides the left manifold 1 into three independent water chambers: the bottom water chamber of the left manifold 1, the middle water chamber of the left manifold 1, and the top water chamber of the left manifold 1. Similarly, the double partition plate 6 divides the right manifold 3 into three independent water chambers: the bottom water chamber of the right manifold 3, the middle water chamber of the right manifold 3, and the top water chamber of the right manifold 3. There are four harmonica tubes 2. The fourth harmonica tube 2 at the bottom is connected to the bottom water chamber of the right manifold 3 and the bottom water chamber of the left manifold 1 at both ends. The first harmonica tube 2 at the top is connected to the top water chamber of the left manifold 1 and the top water chamber of the right manifold 3 at both ends. The second harmonica tube 2 is connected to the top water chamber of the right manifold 3 and the middle water chamber of the left manifold 1 at both ends. The third harmonica tube 2 is connected to the middle water chamber of the left manifold 1 and the middle water chamber of the right manifold 3 at both ends.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it also includes a manifold 8, a single-connector 4, and an inlet / outlet pipe 5. One end of the manifold 8 is connected to the bottom water chamber of the left manifold 1, and the other end is connected to the top water chamber of the left manifold 1. The single-connector 4 is located on the upper side of the middle part of the right manifold 3, and one end of it is connected to the bottom water chamber of the right manifold 3. The inlet / outlet pipe 5 includes an inlet pipe and an outlet pipe. The inlet pipe is connected to the bottom water chamber of the right manifold 3 through the single-connector 4, and the outlet pipe is connected to the middle water chamber of the right manifold 3.

[0024] Coolant is introduced through the inlet pipe and flows into the bottom water chamber of the right manifold 3 via the single-pass 4. Subsequently, the coolant flows from the bottom water chamber of the right manifold 3 into the bottom water chamber of the left manifold 1 through the fourth harmonica tube 2 at the bottom, and then through the manifold 8 from the bottom water chamber of the left manifold 1 to the top water chamber of the left manifold 1. Next, the coolant flows from the top water chamber of the left manifold 1 into the top water chamber of the right manifold 3 through the first harmonica tube 2 at the top, and then through the second harmonica tube 2 from the top water chamber of the right manifold 3 into the middle water chamber of the left manifold 1. After that, the coolant flows from the middle water chamber of the left manifold 1 into the middle water chamber of the right manifold 3 through the third harmonica tube 2, and finally flows out from the outlet pipe, completing the cooling cycle.

[0025] During this process, four double-partition plates 6 within the left manifold 1 and right manifold 3 divide the internal space into three water chambers and two air chambers. The water chambers are used for coolant flow, while the air chambers, located between adjacent water chambers, are used to test the seal. If there are defects in the embedding or sealing of the double-partition plates 6 and the manifolds, coolant will seep into the adjacent air chambers and be discharged through the corresponding leakage holes 601 or captured by the testing equipment. This allows for timely interception of poorly sealed products, preventing cooling failure caused by leakage between water chambers and ensuring the stable cooling effect of the radiator on the new energy battery.
