Application of foam in power battery

 

Foam plays a vital role in the power battery, which is related to the safety of the battery pack and the vehicle. The cooling system inside the battery pack has been converted from traditional air cooling to liquid cooling, but the liquid cooling plate is in direct contact with the battery pack. , Causing the liquid-cooled plate to be in a long-term load-bearing state, and it is an alloy structure, it will produce a certain physical deformation, and the middle position will have a certain collapse, resulting in gaps in the contact interface with the battery module, which is not conducive to heat transfer This requires corresponding support for the liquid-cooling plate structure to prevent deformation of the liquid-cooling plate structure, so as to seamlessly connect with the battery module and facilitate heat transfer. According to the application environment, customers have the following requirements for the performance of liquid-cooled plate support products:

1. Stable support and good shock absorption effect;

2. Excellent temperature resistance and durability;

3. The compression permanent deformation and stress relaxation loss are small;

4. It has excellent flame-retardant properties to ensure the safety of combustion.

solution

In response to customer requirements, our polyurethane foam is specially designed for customer needs to create sealed support foam products. It has a stable and detailed foam structure, strong pore walls, and a thickness of 0.8mm can reach UL94V-0 fire retardant level. , Can work normally in the range of -50-200℃, low smoke and low toxic gas emissions, excellent resilience performance, tested under severe temperature conditions, stress relaxation loss is small, very suitable for customer products in this harsh environment Needs. After several samples and repeated tests, after using this material, it has now entered the stage of use.
