HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2021038860
Kind Code:
A
Abstract:
To appropriately switch execution or stop of heat exchange between a high temperature side heat exchange part and a lower temperature side heat exchange part with a simple structure.SOLUTION: A heat exchanger includes: a first heat exchange wall part 11; a second heat exchange wall part 12; a side wall part 13 disposed between the first heat exchange wall part 11 and the second heat exchange wall part 12 and defining a sealed space; a piston 20 which divides the sealed space into a first space chamber 15 and a second space chamber 16; a rod 25 in which one end side is fixed to the piston 20 and the other end side is inserted into a through hole 11A of the first heat exchange wall part 11 to be supported thereby in a manner that the other end side can move forward or rearward; and a supply/discharge mechanism 30 which may supply a heat insulation fluid to the second space chamber 16 or discharge the heat insulation fluid from the second space chamber 16. When the heat insulation fluid is discharged from the second space chamber 16, the piston 20 comes into contact with the second heat exchange wall part 12. When the heat insulation fluid is supplied into the second space chamber 16, the piston 20 separates from the second heat exchange wall part 12.SELECTED DRAWING: Figure 2
