Description

Technical Field

[0001] The utility model relates to a baking oven, in particular to a circulating air aging and static baking oven. Background Art

[0002] After the battery is processed, it needs to be placed in a high-temperature aging device for aging treatment. The existing aging baking ovens generally use electric heating tubes as heating devices, and the electric heating tubes are evenly distributed on the inner walls of both sides of the baking oven. By heating simultaneously from both sides, the batteries in the oven are baked and aged. However, this heating method will cause the temperature near the side of the baking oven to be relatively high, and the temperature in the middle area of the baking oven to be relatively low. Due to the uneven distribution of heat, the aging effect on the batteries is also inconsistent, which cannot meet the process requirements. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a circulating air aging and static baking oven that can make the heat distribution in the baking chamber uniform, the circulating fluidity of the hot air better, and thus improve the aging effect of the battery, aiming at the deficiencies of the prior art.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions.
