PROBLEM TO BE SOLVED: To obtain a cold-storage heat exchanger capable of achieving cold storing, indoor cooling by a refrigerant tube, and indoor cooling by discharging of a cold storage material, and improving performance of the heat exchanger.SOLUTION: A cold-storage heat exchanger includes a refrigerant passage, a plurality of refrigerant tubes 45 arranged at intervals, and a cold storage material container 47 soldered to the refrigerant tubes 45 to house a cold storage material 50. The cold storage material container 47 includes a plurality of protrusions 47a1 and a plurality of recesses 47a2. The protrusions 47a1 are soldered to the refrigerant tubes 45, and the recesses 47a2 constitute a cold storage material side air passage 461a. The protrusion and the recess shapes of the protrusions 47a1 and the recesses 47a2 are repeated by a plurality of times in the longitudinal and short directions of the cold storage material container 47. A hole portion 47a3 is formed at a portion of the cold storage material container 47 soldered to the refrigerant tube 45, and the cold storage material 50 is brought into direct contact with the refrigerant tube 45 through the hole portion 47a3. |
