Abstract:
1. A cold storage heat exchanger configuring a refrigerant cycle device together with a compressor driven by a vehicle-running power source to compress and discharge a refrigerant, a radiator configured to cool a high temperature refrigerant, and a decompression device configured to decompress the cooled refrigerant, the 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 a refrigerant tube and defines a compartment receiving a cold storage material; an inner fin arranged inside of the cold storage container; 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; and an air-side fin arranged in the cooling air passage and thermally connected to the refrigerant tube, wherein the cold storage container has a concave-convex surface and includes a plurality of recess portions bonded to the inner fin, and a plurality of protrusion portions that protrude outward on an outer side of the recess portions, the protrusion portions of the cold storage container are bonded to an outer surface of the refrigerant tube, the inner fin has a dimension to be bonded to the recess portions; the cooling air passage contacts another refrigerant tube on an opposite side from the refrigerant tube bonded to the cold storage container, such that the cooling air passage is disposed between two of the refrigerant tubes, and the another refrigerant tube contacts another cooling air passage on an opposite side from the cooling air passage contacting the refrigerant tube bonded to the cold storage container.
