Description

Technical Field

[0001] The invention relates to the technical field of battery interlayer thermal insulation, and in particular to a square aluminum shell battery interlayer thermal insulation structure. Background Art

[0002] With the rapid development of the new energy vehicle industry, the performance, safety and reliability of power batteries as its core components have received widespread attention. Square aluminum shell batteries have become one of the mainstreams in the market due to their high energy density, low integration difficulty and relatively low manufacturing cost. However, square aluminum shell batteries also face some technical challenges during use, especially in thermal management. Therefore, it is particularly important to design a reasonable interlayer insulation structure; Currently, there is a single method for insulating the interlayer of square aluminum shell batteries, which is to use foam silicone rubber for insulation. However, due to its porous structure and material properties, foam silicone rubber usually has a low thermal conductivity, which means that while it insulates, it also limits the effective transfer of heat. In the battery pack, if the heat cannot be discharged in time, it may cause the internal temperature of the battery to be too high, affecting the performance and life of the battery. Therefore, corresponding improvements are needed. Summary of the invention

[0003] The purpose of the present invention is to provide a square aluminum shell battery sandwich insulation structure to solve the problem that the existing square aluminum shell battery sandwich insulation structure proposed in the above background technology has a single insulation method and poor thermal conductivity when in use.

[0004] To achieve the above object, the present invention provides the following technical solution: a square aluminum shell battery sandwich insulation structure, comprising an insulation frame and an insulation board, wherein one side of the insulation frame is connected to the insulation board; It also includes: a heat conduction plate is connected to the other side of the heat insulation frame, and heat conduction holes with circular cross-sections are evenly arranged on the heat conduction plate. Both sides of the interior of the heat insulation frame are connected to built-in frames, and heat conduction components are arranged inside the built-in frames.

[0005] Preferably, the heat insulation frame is a hollow frame structure, and an assembly component is arranged outside the heat insulation frame.

[0006] Preferably, the heat-conducting component includes supporting fish frames arranged on both sides of the internal built-in frame, and the supporting fish frames are respectively fixed to the two ends of the outer side of the insulation board, and multiple groups of notches are evenly arranged on the supporting fish frames, and the internal built-in frame is evenly coiled with heat-conducting copper tubes.

[0007] Preferably, the heat-conducting copper tube is evenly stuck in the notch on the supporting fish frame, the heat-conducting copper tube is coiled in a "loop" shape inside the built-in frame, and the heat-conducting copper tube is arranged in a double layer inside the built-in frame.

[0008] Preferably, the assembly component includes a connecting block arranged on the right side of the insulation frame and a docking block arranged on the left side of the insulation frame, both ends of one side of the connecting block are fixed with clamping columns, and locking holes are arranged on the clamping columns, and one side of the docking block is opened with a fixing hole.

[0009] Preferably, the docking block and the clamping column are buckled with each other, and the locking hole and the fixing hole are interconnected.

[0010] Compared with the prior art, the invention has the following beneficial effects: the square aluminum shell battery sandwich insulation structure can not only effectively insulate and quickly conduct heat, but also can be freely assembled to expand the insulation area to meet different usage requirements; The heat insulation frame, the heat insulation plate and the heat conduction plate cooperate with each other to form the prototype of the heat insulation structure, that is, the heat insulation plate and the heat conduction plate are distributed on the front and back sides of the heat insulation frame, and the heat insulation plate and the heat conduction plate are used to separate multiple groups of square aluminum shell batteries, and the heat insulation plate is used for heat insulation, and the heat conduction plate and the heat conduction hole are further used for heat conduction, that is, the contact area with the air is expanded, and the heat generated during the operation of the square aluminum shell battery is quickly discharged, which helps to extend the service life of the square aluminum shell battery; Two layers of heat-conducting copper tubes are evenly coiled on the supporting fish frame inside the heat-insulating frame to form an inner interlayer of the heat-insulating structure. Then, while insulating multiple aluminum shell batteries, the high thermal conductivity of the heat-conducting copper tubes can be used to further quickly conduct the heat during the use of the square aluminum shell batteries, achieving good heat dissipation effect. By matching the docking block with the position of the card column, and matching the locking hole with the fixing hole so that the two are interconnected, and then using the positioning pin to penetrate the fixing hole and the locking hole, multiple groups of insulation frames can be spliced ​​and assembled, extending the use length of the insulation frame, and multiple groups of square aluminum shell batteries can be divided and insulated to meet different usage requirements.
