Technical Field
[0001] The utility model belongs to the technical field of cooling devices, in particular to a cooling device for filling. Background Art
[0002] Before filling the filling liquid, it must be ensured that the liquid is in the appropriate temperature range. The temperature of the coolant directly affects the efficiency and quality of the filling process. Overheated liquid may cause damage to the filling equipment or difficulty in operation, while overcooled liquid may affect the uniformity and stability of the filling. Therefore, before filling, it is usually necessary to cool the coolant to reach a suitable working temperature, so as to ensure the smooth progress of the filling process and ensure product quality and production efficiency.
