ACTIVE TYPE REGENERATIVE MAGNETIC HEAT AMOUNT HEAT ENGINE AND MULTIPLE MATERIAL BLADES FOR ACTIVE TYPE REGENERATIVE MAGNETIC HEAT AMOUNT HEAT ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a magnetic cold heat accumulator or electric calorie cold heat accumulator of which size is decreased and its manufacturing process is improved for its cooling application or a heat pump application.SOLUTION: Multiple material blades used as an active type regenerative cold heat accumulator are comprised of a plurality of elements 2 for dividing a blade main body along its longitudinal direction. Each of the elements is made of various magnetic calorific materials or electric calorific materials properly selected, a plurality of exclusive channels 3 pass through the blade main body 1 and extend along a longitudinal direction of the blade. In order to reduce loss of heat transport, the exclusive channels are provided with a fluid mixing structure, porous layer or hydrophobic coating. In order to reduce cost, the blades of several materials can be attained through an inkjet printing. The blades of several material have curved shape for forming involute type blade main body.SELECTED DRAWING: Figure 3
