Dry Cooler in The Cooling And Molding Process of Plastic Products
Working Principle of Dry Coolers: Dry coolers, also known as dry-type coolers, operate by circulating a liquid (typically a secondary coolant like ethylene glycol solution) through internal tubes while using ambient air flowing externally to cool the liquid, thereby reducing its temperature and achieving cooling.
Applications in Plastic Cooling and Molding: During cooling processes in plastic injection molding, extrusion, and similar applications, dry coolers can be used to cool molds, hydraulic components, and oils. For instance, in injection molding, molds require rapid cooling to enhance productivity and prevent product deformation. Dry coolers provide stable cooling for these molds.
Advantages in Plastic Cooling Applications
Precise Temperature Control: Plastic cooling processes demand accurate temperature regulation to prevent material distortion and shrinkage. Dry coolers meet this requirement, ensuring product quality.
Energy Efficiency: Compared to traditional cooling towers, dry coolers eliminate water usage, conserving water resources. Additionally, the absence of pumps and water circulation systems results in lower energy consumption, aligning with the plastic and rubber industries' demands for energy efficiency and sustainability.
Reliable Operation: Dry coolers feature relatively simple structures with low maintenance requirements. They maintain stable operation during continuous production processes for plastic cooling and molding, minimizing downtime and maintenance costs.
