Description

Technical Field

[0001] The utility model mainly relates to the field of liquid cooling plates, and particularly relates to a support assembly for a liquid cooling plate of a power battery. Background Technique

[0002] ‌‌A liquid cooling plate is a component used for power batteries and energy storage batteries, which cools the battery module through flowing liquid to control the battery temperature;

[0003] The working principle of the liquid cooling plate is that the coolant circulates in the liquid flow channel to transfer away the excess heat, thereby realizing the cooling function. This technology has better heat conduction performance and stability compared with the air cooling system, and can cool or heat the battery module according to the ambient temperature. The design and manufacture of the liquid cooling plate need to consider multiple factors, including high heat dissipation power, high reliability, precise heat dissipation design, and strict requirements for the weight of the cold plate, etc. These requirements stem from the pursuit of energy density by the power battery system, as well as the harsh conditions such as vibration, shock, and high and low temperature alternation that may be encountered in the actual use environment;

[0004] Among them, the liquid cooling plates are connected by a support assembly. However, when the support assembly connects the liquid cooling plates, there will be a gap between the top and bottom liquid cooling plates. When the pressure of the coolant flowing inside the liquid cooling plate is applied, the coolant is likely to flow out through the gap, resulting in coolant leakage.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0031] The top support assembly structure 1 includes a top plate 101, a top fitting strip 103 is arranged at the bottom of the top plate 101, and a slot 104 is formed in the middle of the bottom of the top fitting strip 103;

[0032] The bottom support assembly 2 includes a bottom plate 201, a bottom fitting strip 203 is arranged at the top of the bottom plate 201, the bottom fitting strip 203 is fitted with the top fitting strip 103, a plug strip 204 is arranged in the middle of the top of the bottom fitting strip 203, the outer wall of the plug strip 204 is fitted with the inner wall of the slot 104, and a sealing strip 7 is arranged between the bottom fitting strip 203 and the top fitting strip 103. The top support assembly structure 1 and the bottom support assembly 2 are connected by a side support assembly 5. The coolant enters between the top fitting strip 103 and the bottom fitting strip 203 at different positions through the liquid inlet 6 respectively, so that the coolant flows between the top fitting strip 103 and the bottom fitting strip 203 to cool the power battery placed on the top. Then the coolant flows back into the inside of the liquid inlet 6 and is discharged. The sealing strip 7 is made of silicone with good cold resistance to prevent the sealing strip 7 from shrinking after being cooled. Moreover, the slot 104 and the plug strip 204 cooperate with each other to support the cooling plate, and the sealing effect between the top plate 101 and the first jack 102 can be increased.

[0033] Further, a first jack 102 is provided at the top of the top plate 101. The number of the first jacks 102 is set to be multiple, and the multiple first jacks 102 are evenly distributed on the top of the top plate 101. A second jack 202 is provided at the bottom of the bottom plate 201. The number of the second jacks 202 is set to be multiple, and the multiple second jacks 202 are evenly distributed on the bottom of the bottom plate 201. The cooperation of the first jack 102, the second jack 202 and the side support assembly 5 can clamp the top support assembly structure 1 and the bottom support assembly 2 to avoid gaps between the top support assembly structure 1 and the bottom support assembly 2, resulting in looseness between the top support assembly structure 1 and the bottom support assembly 2, and making the component assembly unable to be firmly sealed.

[0034] Further, a positioning plate 3 is provided between the top plate 101 and the bottom plate 201. A positioning hole 4 is formed inside the positioning plate 3, and a side support assembly 5 is provided outside the positioning plate 3.

[0035] Further, for the side support assembly 5, it includes a side support bar 501. A fixing bolt 502 is threadedly connected in the middle of the side support bar 501. One end of the fixing bolt 502 is threadedly connected to the positioning hole 4. A moving frame 503 is slidably connected to the outer wall of the fixing bolt 502. Bolt holes 504 are formed at both ends of the moving frame 503. An insertion bolt 505 is threadedly connected inside the bolt holes 504. The insertion bolt 505 is in contact with the first jack 102 and the second jack 202. Place the positioning plate 3 between the top plate 101 and the bottom plate 201, then place the side support bar 501 on the outer wall of the positioning plate 3 and insert the fixing bolt 502 into the positioning hole 4, so that the fixing bolt 502 drives the moving frame 503 to fit the outer wall of the side support bar 501. Then rotate the insertion bolt 505, and the insertion bolt 505 moves downward on the inner wall of the bolt hole 504, so that the insertion bolt 505 is inserted into the inner walls of the first jack 102 and the second jack 202, making the top support assembly structure 1 and the bottom support assembly 2 fit together, thus realizing the assembly and sealing of the support assembly.

[0036] Further, a liquid inlet 6 is formed in the middle of the top plate 101, and the liquid inlet 6 communicates with the gap between the top fitting strip 103 and the bottom fitting strip 203.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
