[0002] As sales of new energy vehicles continue to increase, battery pack spontaneous combustion and collision fires are common. Global users are no longer worried about the range of new energy vehicles, but more about the safety of power batteries.
[0003] Conventionally, the insulation core material is vacuum-encapsulated using an encapsulation layer. The encapsulation is relatively cumbersome and has some disadvantages. Here we should highlight why the non-vacuum encapsulation bag mode should be used. Utility Model Content
[0004] The utility model provides a self-sealing non-evacuated airgel heat insulation pad, which is used to solve the deficiencies described in the above-mentioned prior art.
[0005] The technical solution adopted by the utility model is:
[0006] A self-sealed non-evacuated aerogel thermal insulation pad comprises a packaging film bag and an aerogel thermal insulation core material, wherein the aerogel thermal insulation core material is in the packaging film bag and is directly packaged by the packaging film bag; the packaging film bag is provided with at least one packaging joint, a packaging opening is provided at the packaging joint, and a pressing sealing structure is provided at the packaging opening. The aerogel thermal insulation core material is loaded into a packaging film bag of suitable size, and then the packaging film strip is sealed by the pressing sealing structure, and no vacuum is required, and the packaging method is simple and quick.
[0007] As a preferred solution of the utility model, the press-fit sealing structure is a concave-convex press-fit structure. The concave-convex press-fit structure uses concave-convex bite bones, and sealing can be achieved by pressing.
[0008] As a preferred solution of the utility model, the pressing and sealing structure is integrally formed with the packaging film bag, and is formed during direct processing without the need for additional operations, thus simplifying the processing technology of the packaging film strip.
[0009] As a preferred solution of the utility model, the compression sealing structure is edge-sealed at a distance from the edge of the packaging film bag, and the edge-sealing width is 0-5 mm.
[0010] As a preferred embodiment of the utility model, the shape of the packaging film bag is circular, square or irregular. The shape of the packaging film strip is designed according to actual needs, and the packaging joint is set according to the shape characteristics. If it is circular, the packaging joint occupies at least half of the outer circumference, that is, at least half is open and half is closed. The aerogel insulation core material is placed into the packaging film bag from the opening, and then the opening is pressed to seal to form a packaged insulation pad. If it is square, the packaging joint can be set only on one side, or two sides, three sides or even four sides can be packaging joints. After the aerogel insulation core material is placed in place, the concave and convex pressing structure of the packaging joint is pressed to achieve sealing.
[0011] As a preferred solution of the utility model, the packaging film bag is a PET packaging film bag or a PI film packaging film bag.
[0012] As a preferred embodiment of the present invention, the aerogel thermal insulation core material is a core material made of other aerogel materials such as ceramic aerogel, pre-oxidized silk aerogel core material or glass fiber aerogel.
[0013] The utility model uses a packaging film bag with a packaging joint to perform normal packaging of the aerogel insulation core material, does not need to be vacuumed, and the packaging uses a self-sealing bag type compression packaging, which can be packaged quickly and easily. The shape of the packaging film bag can also be designed according to actual conditions. It can be a conventional round, square or unconventional shape. It only needs to form a concave and convex bone at the opening, which increases the diversity of the insulation pad and can meet the insulation pad requirements of different types of battery packs.
