Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production and processing equipment, in particular to a multi-layer cooling furnace for battery cooling. Background Art

[0002] At present, the lithium battery industry at home and abroad has a good development prospect. Lithium-ion batteries have been widely used in portable appliances such as laptops, cameras, and mobile communications due to their unique performance advantages. The large-capacity lithium-ion batteries currently developed have begun to be tried in electric vehicles and are expected to become one of the main power sources for electric vehicles in the 21st century. They will also be used in artificial satellites, aerospace, and energy storage. With the shortage of energy and the pressure of environmental protection in the world, lithium batteries are now widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has further promoted the development and application of the lithium battery industry. In this regard, in order to ensure the high quality of lithium batteries, it is necessary to strictly control the production environment of each process in the lithium battery production process.

[0003] In the production process of lithium batteries, a lithium battery drying furnace is required to dry the battery shell, pole piece, pole coil and battery cell. Among them, the lithium battery drying furnace mainly includes thermal radiation heating, hot air heating and contact heating. Due to the problems of poor heating uniformity, long baking cycle and high energy consumption of radiation heating and hot air heating, the industry has basically replaced them with contact heating. Contact heating is favored by battery manufacturers because the heating plate directly contacts the battery surface, the temperature uniformity is good and the baking cycle is short. Subsequently, the lithium battery after drying often has a temperature higher than normal temperature. Therefore, rapid cooling is required to meet the process production requirements and obtain qualified lithium battery products.

[0004] In the process of cooling the battery, the existing cooling method is to use a battery cooling furnace for cooling and lowering the temperature. Specifically, the cooling furnace is provided with battery slots arranged at equal intervals in a linear manner. The sheet-shaped batteries are inserted into the battery slots at a certain interval, and cold air is blown into the cooling furnace to lower the temperature of the batteries in the cooling furnace, thereby cooling and lowering the temperature of the dried batteries. In the process of cooling the battery using the existing cooling furnace, each battery needs to be transferred from the drying furnace to the cooling furnace before the battery can be lowered and cooled, resulting in low cooling and lowering efficiency of the existing cooling furnace for the battery.

[0005] Therefore, it is necessary to propose a multi-layer cooling furnace for battery cooling to improve the above-mentioned defects. Utility Model Content

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and implementation modes:

[0029] It should be noted that when drying the battery, the battery is generally placed in a fixture, and then the battery and the fixture are placed in a drying furnace for drying. The dried battery then needs to be taken out for cooling. Specifically, when cooling and lowering the temperature of the battery, the existing battery cooling furnace generally needs to take the battery out of the fixture, and then arrange the single-piece batteries in sequence and insert them into the cooling chamber of the battery cooling furnace to cool and lower the temperature of the battery. The process of taking the battery out of the fixture and transferring it to the cooling chamber is relatively cumbersome and requires more manpower, which ultimately reduces the cooling efficiency of the battery. In addition, the existing battery cooling furnace needs to set all batteries on the same horizontal plane, which results in a larger footprint of the battery cooling furnace.
