Abstract
A heat exchanger includes a partition wall that separates two fluids having different temperatures. The partition wall includes a side circumferential portion, and a bottom portion configured to close an opening on one side of the side circumferential portion. Fins are formed on an outer surface of the partition wall, and arranged side by side in a circumferential direction around a center of a cylinder of the side circumferential portion. Each of the fins includes a base portion connected to an outer surface of the bottom portion. Plate-shaped members are provided between the base portions of the fins adjacent in the circumferential direction, and fixed to the outer surface of the bottom portion. The partition wall and the plurality of fins are integrally molded of a same material. The plate-shaped members are formed of a different material of higher emissivity or heat resistance than the material of the fins.
