1. A heat exchanger with a thermal storage function, comprising:
a plurality of heat exchange tubes through which a medium is to flow; a plurality of thermal storage material containers in which a thermal storage material is provided, each of the thermal storage material containers being made of metal and provided such that heat of the medium which flows through the heat exchange tubes is transferred to the thermal storage material within each of the thermal storage material containers, each of the thermal storage material containers including a peripheral edge portion and a cylindrical portion provided at the peripheral edge portion to establish communication between an interior and an exterior of each of the thermal storage material containers; and a first thermal storage material charging member having a cylindrical shape extending along a longitudinal axis thereof, the first thermal storage material charging member being made of metal and including a thermal storage material charging passage and an inner circumferential surface formed by a metal bare material, the first thermal storage material charging member including a first end and a second end opposite to the first end, the first end being provided in and brazed to the cylindrical portion of one of the thermal storage material containers, the second end projecting from the cylindrical portion and being collapsed from opposite sides in a radial direction of the first thermal storage material charging member, a circumferential wall of the first thermal storage material charging member being deformed such that a collapsed portion is formed on the first thermal storage material charging member and the thermal storage material charging passage is closed and sealed, the collapsed portion of the first thermal storage material charging member including a first collapsed part and a second collapsed part which is adjacent to the first collapsed part in a longitudinal direction of the first thermal storage material charging member and which is greater in degree of collapse than the first collapsed part, a relation T2<T1<2t being satisfied where “t” represents a thickness of the circumferential wall of an uncollapsed portion of the first thermal storage material charging member, “T1” represents a thickness of the first collapsed part, and “T2” represents a thickness of the second collapsed part, wherein, in both the first collapsed part and the second collapsed part, the opposite sides of the first thermal storage material charging member are in contact with each other, wherein the first collapsed part and the second collapsed part extend laterally with respect to the longitudinal axis of the first thermal storage material charging member, and wherein the first collapsed part and the second collapsed part extend laterally across an entire width of the first thermal storage material charging member. |
