Uniform temperature roller system having uniform heat exchange by supercritical fluid

Abstract

A uniform temperature roller system for uniform temperature exchange by supercritical fluid is revealed. The system includes a roller body, a pair of rotary shafts, a plurality of heating/cooling modules and a supercritical fluid. The roller body includes a first chamber, a second chamber and a third chamber. The second chamber is a closed space and the two rotary shafts are formed on two lateral plates of a housing of the roller body correspondingly. The heating/cooling modules are mounted in the second chamber and the supercritical fluid is filled in the second chamber for transferring temperature between the heating/cooling modules and the roller shell. Thereby the uniform temperature roller system achieves heating or cooling quickly with uniform heat exchange so as to improve quality and yield rate of the product as well as extend service life of the roller.
