Waste heat generated in the industrial production or refrigeration process is generally guided away by cooling water, because the waste heat of large-scale equipment is more, the cooling water carrying the waste heat is basically adopted to carry out heat exchange with air in a tower by a cooling tower, so that the waste heat is transmitted to the air and is dissipated into the atmosphere, thereby completing heat dissipation, but the manufacturing cost of the cooling tower is higher, for small-scale equipment, the cooling tower is too wasted, for example, in a film coating machine, a circulating cooling system is needed to prevent the machine from being overheated to cause production accidents, and because a film coating test line belongs to the small-scale equipment, the heat output is less, if the traditional cooling tower type heat exchange equipment is adopted, the expenditure cost of the cooling system and the operation cost of the equipment are greatly increased, so a small-scale circulating cooling system is needed to be designed;
