Title:
FLUID HEATING APPARATUS
Document Type and Number:
Japanese Patent JP2003317915
Kind Code:
A
Abstract:
To improve heating efficiency in a fluid heating apparatus heating a fluid to be heated by electromagnetic induction.
In a heating bend pipe 1 tubularly formed by a conductive material and having a bent portion 1c formed by spirally bending a passage, to compose a closed circuit by short-circuiting both sides of the bent portion 1c, one side 1d of the bent portion 1c is bent back toward another side, extended to the other side and electrically connected via a short-circuiting tool 9, short- circuiting is provided by using the heating bend pipe itself through which the fluid to be heated passes, and the fluid to be heated is efficiently heated by heating of a current flowing in the closed circuit.
