ELECTRIC HEAT PIPE HAVING TWO TYPES OF ELECTRIC HEATING WIRES

摘要

The present invention relates to a kind of heating tubes, use electric energy. More particularly it relates to which a kind of electrothermal tube, the inside of the heat-transfer pipe with head media and electric heating body heating are for heating by electric heating body. Electrothermal tube further includes a double metal temperature switch, to stop power to be applied to electric heating body, when thermal medium be more than predetermined temperature and prevent power be applied to electric heating body be stop from when thermal medium be not be more than predetermined temperature. ;The 2016 of copyright KIPO submissions
