CONTAINER FOR COLD STORAGE MATERIAL, HEAT-REGENERATOR BODY USING THE SAME AND REGENERATIVE HEAT EXCHANGER BODY

摘要

PROBLEM TO BE SOLVED: To provide a container for accommodating a cold storage material capable of easily setting the cold storage time and the cooling time to desired values by providing two or more regions different in overall heat transfer coefficient for heat transmitted from inside to outside or from outside to inside the container. ;SOLUTION: A container 1 constituting a heat regenerator body accommodating a cold storage material 2 therein is formed of a bag made of two or more parts different in overall heat transfer coefficient for heat transmitted from inside to outside or from outside to inside the container, for example, two film materials 3 and 4 different in thickness from each other bonded together at the peripheries thereof. The heat regenerator body accommodates a cold storage material 2 between the film materials 3 and 4. The difference in thickness between the film materials 3 and 4 makes it possible to change the overall heat transfer coefficient and separately set the regenerating period of time and the cooling period of time without being influenced by each other. In addition, one of the two film materials may be a laminated film having at least a plastic film and metal foil.;COPYRIGHT: (C)2001,JPO
