PURPOSE:To obtain the title evaporator to be heated without directly overheating a heating medium by an electric heater, having high thermal conductivity by equipping a circulating pipe line to communicate a heating chamber with an oil chamber and further an electric heater at the periphery of conduit part of funnelshaped collecting pipe. CONSTITUTION:A heating medium oil around an electric heater 19 is heated by a heating chamber 18, the specific gravity of the oil is reduced, the oil is raised in a circulating pipe line 38, sent to an oil chamber 23 and further circulated through a heat transfer pipe 14 and a collecting pipe 39 to the heating chamber 18. The heating medium oil discharged from a conduit 40 of the collecting pipe 39 flows along the electric heater 19, recycled to the circulating path line 39 and circulated. |
