PROBLEM TO BE SOLVED: To provide a heat exchanger capable of reducing the number of components, being easily manufactured and having a long flow channel for inside fluid in a heat exchanger core having a circular flat outer periphery matched to an outer periphery of a blower fan. SOLUTION: In this heat exchanger, a flat tube 1 is bent spirally or in a meandering state over one around in a plane, the whole plane outer periphery is formed into the circular shape, a fin 2 is mounted between opposite faces of the bent flat tube 1, and inside fluid inlet and outlet ports 3 are formed on one end and the other end of the flat tube 1 to constitute a heat exchanger core 4. The air is blown to an outer face of the flat tube 1 and the fin 2 by the blower fan 5 mounted in opposition to the heat exchanger core 4. COPYRIGHT: (C)2005,JPO&NCIPI
