A COLD STORAGE HEAT EXCHANGER

摘要

A cold storage type heat exchanger is provided to form cold storage material receiving parts by extending single plates forming tubes to be separated defined from refrigerant paths, thereby reducing required parts for manufacturing the heat exchangers and improving productivity. A cold storage type heat exchanger includes unit tubes(10) respectively formed by joining a pair of single plates(11) defining a refrigerant path, cold storage material receiving parts(50) respectively extended from air-passing surfaces of the single plates integrally and having a chamber(51) for receiving hold storage materials. A cold storage material injection element(60) is formed at upper or lower parts of the cold storage material receiving parts for injecting the cold storage materials to the chambers.
