Abstract (en)
[origin: JPH01313882A] PURPOSE: To maintain an electrode under load with high reliability and durability without decreasing thermal efficiency by enabling electrical coupling arbitrary two tube elements in a heat exchanger constituted to circulate cooling fluid, while the space between them is found in only one place. CONSTITUTION: A device has a heat exchanger 6' which is arranged on substantially the same plane, and composed of one or more tubes 6 made of a non- magnetic metal, and cooling fluid circulates in the tubes 6. Arbitrary two tube elements in the tubes 6 or tube elements are electrically connected only at one place and an electric circuit (loop) cannot be made between the tubes in the adjacent or not adjacent to each other or between parts of the tubes. As a result, two opposite functions, that is, a function to protect the electrode from heat by doing a compulsory cooling with a heat exchanger composed of a metal tube and a function of maintaining an inducement device to high heating efficiency can be mutually harmonized.
