Dry Cooler for Plastic Production Room

Dry Cooler for Plastic Production Room

The dry cooler cools the liquid inside the tube by going inside the tube and the natural air outside the tube. The heat generated in the process of plastic production is transferred to the cooling liquid inside the tube, and then the cooling liquid, when flowing through the dry cooler, exchanges heat with the outside air through the tube wall and radiates the heat into the air, thus lowering the temperature of the liquid inside the tube and achieving the purpose of cooling.

Dry cooler can rely on natural convection, that is, the hot air naturally rises, the cold air naturally replenishes, realizes the flow of air to take away the heat; Can also be installed through the fan for forced convection, accelerates the flow of air, improves the efficiency of heat dissipation.

Advantages

Water saving: compared with the traditional water-cooled cooler, dry cooler has no water consumption during the working process and does not need a large amount of water resources for cooling, which is especially suitable for water-scarce areas.

Environmental protection: because it does not use water as a cooling medium, it avoids the environmental pollution problems that may arise in the process of water evaporation and discharge, such as wastewater discharge, scale formation and so on.

Convenient installation and maintenance: dry cooler structure is relatively simple, does not require complex water treatment systems and circulating water pipelines, installation and maintenance costs are low, and covers a small area, can be flexibly installed according to the workshop layout.

Stable operation: not affected by water quality, water temperature and other factors, the operation is more stable and reliable, can maintain a better cooling effect in different environmental conditions, reducing the risk of production interruption due to cooling system failure.

Application Scenario

Injection Molding Process: During the operation of the injection molding machine, the mold and the hydraulic system will generate a large amount of heat. The dry cooler can be used to cool the mold and the hydraulic oil to ensure the quality and efficiency of the injection molding, and to prevent the mold from overheating which leads to deformation of the plastic products, shrinkage and other defects.

Extrusion molding process: when the extruder is extruding plastic profiles, pipes and other products, the screw and barrel will generate heat, the dry cooler can be used to cool the screw and barrel, control the temperature of the plastic, so that it can be extruded in the appropriate range to ensure the dimensional accuracy and performance of the product.

Blow molding process: In the blow molding process, the molds need to be cooled quickly in order to shape the plastic products, the dry cooler can be used to cool the molds and improve the production efficiency and product quality.
