Abstract
PURPOSE: To accomplish the work for heating and subsequent cooling with the same equipment by mounting a heating wire into an electric insulator filling a clearance between inner and outer pipes forming a double pipe with a cooling medium in/ outlet at both ends of the inner pipe.
CONSTITUTION: A heat-proof electric insulating agent 3 such as MgO fills a space between an inner pipe 1 and an outer pipe provided on the concentric circle and a heating wire such as nichrome wire provided into the agent along the entire length of the outer pipe. The inner pipe 1 is extended from both ends of make a cooling medium in/outlet. With such an arrangement, when energized, the heating wire generates a Joule heat to heat the surrounding atmosphere. If the wire is deenergized and a cooling medium is passed through the inner pipe from the cooling medium in/outlet, the cooling is conducted.
