An aluminum alloy clad material includes a core material, one side being clad with cladding material, the other side being clad with cladding material, the core material including an aluminum alloy that includes 0.5 to 1.8% of Mn, and limited to 0.05% or less of Cu, with the balance being Al and unavoidable impurities, the cladding materialincluding an aluminum alloy that includes 3 to 10% of Si, and 1 to 10% of Zn, with the balance being Al and unavoidable impurities, and the cladding materialincluding an aluminum alloy that includes 3 to 13% of Si, and limited to 0.05% or less of Cu, with the balance being Al and unavoidable impurities, wherein the Si content X (%) in the cladding materialand the Si content Y (%) in the cladding materialsatisfy the value (Y&#x2212;X) is &#x2212;1.5 to 9%.

Aluminum alloy cladding material for heat exchanger

A cold storage heat exchanger has refrigerant pipes fins, and cold-storage-medium containers. The cold-storage-medium container is arranged next to the refrigerant pipe. A cold storage medium is accommodated in the cold-storage-medium container in order to leave an air cell, and to provide a filling ratio of less than 90%. The cold-storage-medium container has a plurality of depressions at an inside of the cold-storage-medium container. The depression is a dimple. The plurality of depressions are joined each other at top parts and provide high rigidity. The cold-storage-medium container is positioned on the refrigerant pipe by an engaging projection. An open end of an open depression is covered by the refrigerant pipe. The cold storage medium can flow into the open depression. Therefore, the cold storage medium may directly contact the refrigerant pipe, and is directly cooled with the refrigerant.

Cold storage heat exchanger

A cold storage heat exchanger has refrigerant pipes and a cold storage material. Each of the refrigerant pipes has a refrigerant passage therein. The refrigerant pipes are arranged so as to be distanced from each other with clearances therebetween. The cold storage material is disposed in at least one of the clearances. At least another one of the clearances provides an air passage. The heat storage material is disposed in at least two of the clearances arranged adjacent to each other.
