PROBLEM TO BE SOLVED: To provide a heat exchanger capable of exhibiting a heat storage effect by latent heat so as to correspond to a temperature change generated during both a cooling operation and a heating operation or generated while the heat exchanger operates.SOLUTION: A heat exchanger for vehicle air conditioning according to the present invention comprises a laminate in which a plurality of tubes and a plurality of outer fins are alternately laminated. Each tube has a structure in which a first closing plate is bonded to a second closing plate or a structure in which at least one intermediate plate is sandwiched between the first closing plate and the second closing plate. Each tube includes a refrigerant path communicating with tank parts provided on longitudinal both ends of the tube. Two or more of the tubes each include a storage portion in which a heat storage medium can be stored and that does not communicate with the refrigerant path. The laminate includes a plurality of filled spaces each of which includes a storage portion and that do not communicate with one another. The filled spaces include a first divided space filled with a first heat storage medium and a second divided space filled with a second heat storage medium different in a phase transition temperature from the first heat storage medium. |
