A cold storage heat exchanger includes: a plurality of refrigerant tubes disposed at intervals, each of the refrigerant tubes including a refrigerant passage that allows a refrigerant to flow therethrough; a cold storage material adjacent to the refrigerant tubes; and a heat transfer suppressor that suppresses heat transfer from the refrigerant tubes to the cold storage material in an overheated area of the refrigerant formed in the refrigerant passage.

Cold storage heat exchanger

An evaporator includes multiple cold storage mechanisms for lowering a temperature of a cold storage material housed inside a cold storage container by heat exchange with a refrigerant. The multiple cold storage mechanisms include a first cold storage mechanism and a second cold storage mechanism higher in heat storage-and-radiation performance than the first cold storage mechanism.

Evaporator

A cold storage heat exchanger includes a plurality of tubes, a coolant flowing in the tubes, a cold storage material container joined to the tubes, the cold storage material container defining a room that houses a cold storage material, and a distribution tank unit that distributes the coolant to the tubes. A coolant passage is formed in the tubes and the distribution tank unit. The distribution tank unit includes an aperture plate that reduces a passage cross-sectional area of the coolant passage. Among the plurality of tubes, the cold storage material container is joined to at least a tube disposed upstream in a coolant flow direction from the aperture plate in the coolant passage. Accordingly, cold storage performance may be improved.
