[0027] In order to improve the performance of cells, during the manufacturing process of cells, especially in the preparatory work of injecting electrolyte into the cell housing, it is necessary to first heat and dry the cell housing, and then cool the cell housing. Conventional cooling methods mainly include natural cooling and air cooling. Under natural cooling, the cooling time of the cell housing is long, which will lead to a long production cycle and low production efficiency.

The cooling fan provided in the cooling furnace 100 can provide cooling airflow in the cooling furnace 100, so that the cells entering the cooling furnace 100 can be cooled down while moving along with the conveying device 110. The cooled cells continue to move along with the conveying device 110 and are conveyed out of the cooling furnace 100 to enter a next processing step. In an embodiment, the conveying device 110 may also be fully accommodated in the cooling furnace 100. The cells are conveyed to the conveying device 110 accommodated in the cooling furnace 100 by other conveying device, and are driven by the conveying device 110 so that the cells can move relative to the cooling furnace 100. After the cooling of the cells is completed, the cells are conveyed out of the cooling furnace 100, and then transported to the next processing step by other conveying device.

[0047] It should be noted that all of the directional instructions in the embodiments of the present application (such as, up, down, left, right, front, rear.....) are only used to explain the 12 relative position relationship and movement of each component under a specific attitude (as shown in the drawings), if the specific attitude changes, the directional instructions will change correspondingly.

[0048] Besides, the descriptions in the present application that refer to "first", "second", etc. are only for descriptive purposes and are not to be interpreted as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. In addition, the meaning of "and / or" appearing in the full text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution in which both A and B are satisfied. In addition, technical solutions between the embodiments can be combined with each other, but must be based on the realization of the technical solutions by those skilled in the art, and when the technical solutions are contradictory to each other or cannot be realized, the technical solutions should be considered that the combination does not exist, and the technical solutions are not fallen within the protection scope claimed in the present application.

[0049] The above contents are only some embodiment of the present application, and do not limit the scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the scope of the present application.
