Abstract
A cold storage heat exchanger includes refrigerant tubes having therein refrigerant passages and arranged to provide a clearance therebetween. A cold storage container is bonded to a refrigerant tube and defines therein a compartment receiving a cold storage material. The cold storage container has protrusion portions protruding outward and being in contact with the refrigerant tube.
Claims2
A cold storage heat exchanger comprising:
- a plurality of refrigerant tubes having therein refrigerant passages, and arranged to provide a clearance therebetween;
- a cold storage container that is bonded to the refrigerant tube and defines therein a compartment receiving a cold storage material;
- and
- a cooling air passage in which air flows to cool a space to be cooled in a cold storage time of the cold storage material and in a cold release time of the cold storage material, the cooling air passage being provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container bonded to the refrigerant tube, wherein
- an outer surface of the cold storage container, onto which the refrigerant tube is bonded, is provided with a plurality of protrusion portions or a plurality of recess portions.

A cold storage heat exchanger comprising:
- a plurality of flat tubes having therein refrigerant passages, and arranged to provide a clearance therebetween;
- and
- a cold storage container disposed in the clearance and bonded to at least one of the plurality of flat tubes, the cold storage container having therein a compartment receiving a cold storage material, wherein
- the cold storage container has a plurality of protrusion portions protruding outward of the cold storage container and being in contact with a flat surface of the at least one flat tube, and
