High cooling performance increases production speed! No condensation occurs on the surface, allowing for reduced resin changeover time.
The "Heat Pipe Cooling Roll" is a high-performance cooling roll that applies heat exchange technology and the principles of heat pipes to cover the shortcomings of traditional spiral structures. To achieve uniform cooling of the roll surface, it improves quality without cooling unevenness. It prevents condensation on the surface, thereby reducing resin change time. It solves issues such as "the occurrence of condensation (during operation and when stopped)" and "variability in roll surface temperature" found in spiral cooling rolls. 【Features】 ■ Uniform cooling of the roll surface ■ Improved quality without cooling unevenness ■ Increased production speed with high cooling performance ■ No condensation due to high temperatures at both ends *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Cooling Principle】 ■1. Start of rotation, movement of working fluid - When rotation begins, the working fluid adheres to the inner wall due to centrifugal force. ■2. Extrusion of film, contact with roll - The high-temperature film comes into contact with the roll. ■3. Evaporation of working fluid - The working fluid absorbs heat from the high-temperature film and evaporates. ■4. Condensation of working fluid - The evaporated working fluid comes into contact with the cooling water pipe and condenses. ■5. Movement of working fluid to the inner wall - The condensed working fluid is propelled by centrifugal force and adheres to the inner wall again. ■6. Repetition of steps 1 to 5 - By repeating this cycle, the film is cooled. *For more details, please refer to the PDF document or feel free to contact us.*
