Title:
COLD-STORAGE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2022/044741
Kind Code:
A1
Abstract:
This cold-storage heat exchanger is provided with: a plurality of refrigerant pipes (45); and a cold storage material container (47) disposed between the plurality of refrigerant pipes. On plates of the cold storage material container, annular projections (47a) that project toward the sides of the refrigerant pipes opposing the projections are formed. The projections are joined to the refrigerant pipes opposing the projections. Gap spaces (GS) are formed between plates (471, 472), on which the projections are formed, and opposing refrigerant pipes. On inner circumferential sides of the projections of the plates, through holes (473), each of which connects between a housing space of the cold storage material container and the gap space, are formed. The housing space of the cold storage material container is filled with a cold storage material. At least a gas having a lower thermal conductivity than the cold storage material is sealed in each of the gap spaces.
