Description

Battery carrier with heat exchange function

Technical Field

Background

In the manufacturing process of the battery, a drying step is a critical link, specifically, the battery needs to be subjected to operations of multiple coating, dip coating and the like in the manufacturing process, so that a plurality of batteries also need to be dried in the tail end working procedure of the production process. The drying purpose is to remove moisture or other volatile substances in the materials such as paint, solvent and the like, so that the electrode and the electrolyte form tight combination, and meanwhile, the components and the content of the electrode and the electrolyte are ensured to be unchanged, and the performance and the safety of the battery are ensured.

The conventional battery drying method uses air convection type drying, i.e., by heating air to flow, the moisture on the surface and inside of the battery is volatilized. However, in the method, due to the mode of air convection, the moisture on the surface of the battery volatilizes relatively fast, but the moisture in the battery volatilizes relatively slowly, so that the drying efficiency is relatively low.

For this reason, the industry has developed a technology of directly heating a carrier, which mainly includes a heating element in a bottom plate of the carrier, where the heating element may be a heater or a heating runner. The carrier with the processing function also has certain defects due to structural reasons, specifically speaking, the existing battery carrier adopts a flat plate heating structure, and the heating source of the structure is only arranged at the bottom, so that the contact area with a battery is smaller, the heat conduction rate is lower, the heating rate of the battery in a remanufactured product is influenced, in addition, the flat plate heating structure is easy to generate a hot spot phenomenon, the local overheating of the battery is caused, and the service life and the safety of the battery are negatively influenced.

In addition, the dried battery needs to be cooled, if the carrier is used for heat exchange during the cooling process, the cooling speed can be obviously accelerated, the carrier is required to have a cooling function, and the same problem as the heating exists in that the cooling rate of single-sided cooling is low, and the production period of the battery is prolonged.

In summary, the heat exchange of the existing carrier is a basic technical requirement, but the existing carrier has a simple heat exchange structure and low heat exchange efficiency, and the structure still needs to be improved.
