<P>PROBLEM TO BE SOLVED: To provide a compact fluid heating apparatus using induction heating which has high heating efficiency. <P>SOLUTION: A fluid heating apparatus comprises: a fluid channel 11 which includes straight tubes 12 made of a conductive metal material arranged in parallel with gaps therebetween, and U-shaped connection paths 13 arranged on one side and the other side of each of the straight tubes 12 to connect all the straight tubes 12 in series, and which has an inlet and an outlet while its entire part forms one flow channel; and an induction coil 20 which is wound around so as to surround all the straight tubes 12, and which flows high-frequency induction current through each of the straight tubes 12. The both sides of the straight tubes 12 are supported by tube plates 14 and 15, and the straight tubes 12 are made of the metal material which is non-magnetic and corrosion-resistant. <P>COPYRIGHT: (C)2012,JPO&INPIT |
