摘要：

In this paper, the authors explore the structure and operating mechanism of the energy-saving type multi-channel drying cylinder, which can be used in papermaking machine dryer section to effectively reduce the amount of condensate water, and tackle such problem as the water condensation in drying cylinder. This paper theoretically expatiates upon the heat transfer mechanism of the multi-channel drying cylinder of energy-saving type and verifies the theoretical results with numerical simulation approach, which proves that energy-saving type multi-channel drying cylinder can effectively improve the heat transfer efficiency, and increase the productivity of the papermaking machine while the drying cylinder is featured by high cost in manufacturing and non-uniformity in surface temperature because of its peculiarity of configuration, which need to be investigated and improved.
