[0020] like Figure 1-3As shown: This embodiment provides a lithium battery drying device, including a drying chamber 100. The drying chamber 100 has a placement rack 200 inside, which includes a placement plate 210 and a partition plate 220. The placement plate 210 and the partition plate 220 are perpendicular. The partition plate 220 divides the placement plate 210 into multiple placement chambers 230. Placement chambers 230 are formed between adjacent partition plates 220 and the placement plates 210 between them. The drying chamber 100 also has a heat-conducting pipe 300 inside. The heat-conducting pipe 300 is a heat-resistant pipe, such as... Figure 1 As shown, there are three heat pipes 300, each corresponding to a placement chamber 230 in a vertical row. The heat pipes 300 are connected to the air outlet 301 of the hot air blower via pipes. Figure 3 As shown, the heat pipe 300 has multiple air outlets 301. This utility model can achieve efficient and rapid drying of the items to be dried by guiding the hot air generated by the hot air blower into the heat pipe 300 in the drying box 100 through the pipe and then blowing it out through the air outlets 301 on the heat pipe 300 onto the items to be dried on the rack 200, which is more time-saving and labor-saving.
