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. Cet échangeur thermique d'entreposage frigorifique est pourvu : d'une pluralité de tuyaux de réfrigérant (45) ; et d'un contenant de substance d'entreposage frigorifique (47) disposé entre la pluralité de tuyaux de réfrigérant. Sur des plaques du contenant de substance d'entreposage frigorifique, des saillies annulaires (47a) qui font saillie vers les côtés des tuyaux de réfrigérant opposés aux saillies sont formées. Les saillies sont reliées aux tuyaux de réfrigérant opposés aux saillies. Des espaces (GS) sont formés entre les plaques (471, 472), sur lesquelles les saillies sont formées, et des tuyaux de réfrigérant opposés. Sur des côtés circonférentiels internes des saillies des plaques, des trous traversants (473), reliant chacun un espace de réception du contenant de substance d'entreposage frigorifique et l'espace, sont formés. L'espace de réception du contenant de substance d'entreposage frigorifique est rempli d'une substance d'entreposage frigorifique. Au moins un gaz ayant une conductivité thermique inférieure à celle de la substance d'entreposage frigorifique est contenu hermétiquement dans chacun des espaces. 蓄冷熱交換器は、複数の冷媒管(45)と、複数の冷媒管の間に配置された蓄冷材容器(47)と、を備える。蓄冷材容器のプレートには、対向する冷媒管側に向かって突出する環状の凸部(47a)が形成される。凸部は、対向する冷媒管と接合される。凸部が形成されたプレート(471、472)と対向する冷媒管との間には隙間空間(GS)が形成される。プレートの凸部の内周側には蓄冷材容器の収容空間と隙間空間の間を連通する貫通孔(473)が形成されている。蓄冷材容器の収容空間に蓄冷材が充填されるとともに、隙間空間に蓄冷材より熱伝導率の低い気体が少なくとも封入されている。
