<p>PROBLEM TO BE SOLVED: To depress the position deviation of cold storage material containers.SOLUTION: A cold storage heat exchanger 10 comprises: a plurality of flat refrigerant pipes 16 juxtaposed at predetermined intervals between two tanks, these pipes communicating with the two tanks and being in a state that each flat part bent U-shape; and a plurality of cold storage material containers 20 to be encapsulated with a cold storage material, which are fixed at gaps between parts of the refrigerant pipes 16L and 16R adjacent to each other. The cold storage material container 20 includes: a body 20a, into which the cold storage material is encapsulated; and a packed tube 20b extending from the body 20a and protruding in the outside of the gap to form a filling port for the cold storage material. The packed tube 20b includes a pair of slits 46a and 46b formed by forming cutouts towards the body 20a at the end of the packed tube 20b. When the cold storage material container 20 is inserted into the gap, the pair of slits 46a and 46b are positioned to align in a juxtaposition direction of the plurality of refrigerant pipes 16. In a state that the container is inserted in the gap, the cold storage material container 20 is positioned and fixed so that the pair of slits 46a and 46b overlap between the plurality of cold storage material containers 20 in the juxtaposition direction.</p> |
