Abstract: PURPOSE: To facilitate maintenance for a heat exchanger or other component parts by providing a contact type temperature sensor for stopping a heater to prevent overheat of a temperature sensitive part on the outside of a jacket casing and in the heat transferring state to the heat exchanger. CONSTITUTION: A contact type temperature sensor 12 functioning as a temperature safety device is arranged on the outer surface of a jacket casing 7 near a closed end of a heat exchanger 5. A projection 13 is formed in an arrangement area for the contact type temperature sensor 12 of the heat exchanger 5, and a projection 14 is formed on the opposite side to form a direct contact part between the jacket casing 7 and the heat exchanger 5. Thus, the contact type temperature sensor 12 and the heat exchanger 5 are connected to each other to be thermally conductive. The sensor 12 is connected to a control device by lines 15, 16. This arrangement simplifies the constitution for heater protection.
