[0017] The top of the water pump 4 is fixedly connected with a first liquid inlet 14, and a liquid inlet pipe is connected to the first liquid inlet 14 to supply cold liquid to the water pump 4.

[0018] The spray direction of the atomizing nozzle 5 faces the cooling coil 9 to reduce the temperature at the upper end of the cooling coil 9. At the same time, the cold mist ejected by the atomizing nozzle 5 slightly adheres to the carbon fiber prepreg, and the airflow blown by the fan 15 accelerates the evaporation rate of the cold mist to quickly reduce the temperature of the carbon fiber prepreg.

[0019] The cross frame 8 is of a type-II shape with the upper base side longer than the lower base side. Both sides of its upper base are connected with fans 15, and the fans 15 are fixedly connected to the bottom plate 1.

[0022] The first conveying roller 3 and the second conveying roller 13 are on the same horizontal plane and their height is slightly higher than that of the cooling coil 9. The hot-pressed carbon fiber prepreg is conveyed to the upper part of the cooling coil 9 through the first conveying roller 3, and the carbon fiber prepreg after temperature reduction is conveyed to the film laminating device through the second conveying roller 13. The first conveying roller 3 and the second conveying roller 13 play a role of mid-range support.
