[0020] The lithium battery slurry enters the inner box 1 through the first liquid inlet pipe 4, and then the inner box 1 is cooled by the coolant in the interlayer space 3, which can quickly cool the lithium battery slurry, thereby ensuring that the coating material will not be scalded by high temperature during the production and coating of the lithium battery.

[0021] See also Figure 2 , Figure 3As shown, a second liquid inlet pipe 21 and a second liquid outlet pipe 22 connected to the interlayer space 3 are provided on the outer wall of the outer box 2. The coolant is pumped into the interlayer space 3 from the second liquid inlet pipe 21, then flows in the interlayer space 3, and finally flows out through the second liquid outlet pipe 22, and circulates, thereby being able to quickly cool the lithium battery slurry in the inner box 1.

[0022] Furthermore, a spiral sheet 31 is spirally wound in the interlayer space 3, the inner side of the spiral sheet 31 is fixedly connected to the outer wall of the inner box 1, and the outer side of the spiral sheet 31 is fixedly connected to the inner wall of the outer box 2, and a spiral conveying path is formed, and the second liquid inlet pipe 21 and the second liquid outlet pipe 22 are respectively arranged at both ends of the spiral conveying path, and the coolant flows in the spiral conveying path; thereby, the coolant can flow spirally on the outer wall of the inner box 1, so that the lithium battery slurry can be evenly cooled.

[0023] Preferably, the spiral blade 31 is made of copper alloy, which has good thermal conductivity and improves the speed of heat transfer.
