Dry Cooler for Plastic Injection Moulding Machines Free Cooling System
Working Principle: Normally, the flow in the tube is glycol solution, which is cooled naturally by dry cooler through heat exchange with outdoor cold air to obtain cold quantity. Then the low-temperature glycol solution is sent into the cooling part of the injection molding machine by the circulating pump to absorb the heat generated by the injection molding machine, and then flows back to the dry cooler to cool again, so the cycle repeats to achieve the purpose of cooling for the injection molding machine.
Advantages:
Good energy-saving effect: it can make full use of the outdoor natural cold source, when the outdoor temperature is low, it can directly cool the glycol solution through the dry cooler, which reduces or eliminates the need of compressor refrigeration and reduces the energy consumption.
Water-saving and environmental protection: compared with the traditional water-cooling method, there is no water consumption during the working process of the dry cooler, and there is no need for additional water replenishment and water treatment facilities, which is suitable for areas with tight water resources, and also reduces environmental problems such as sewage discharge.
Convenient maintenance: adopting fan motor with very low maintenance requirement, it is suitable for all kinds of climatic conditions, and the structure of the equipment is relatively simple, which doesn't need complicated water circuit system and reduces the maintenance workload due to scale, corrosion and other problems.
Design Points: The cooling capacity of the dry cooler needs to be determined according to the power and heat generation of the injection molding machine to ensure that it can meet the cooling demand of the injection molding machine. At the same time, to consider the installation space, choose the appropriate size and structure. Also need to pay attention to the dry cooler fan power, air volume and other parameters, as well as its adaptation to the ambient temperature range, in order to ensure that in different seasons and environmental conditions can work properly.
