IPC: F28D15/02
Filed: 1988-11-04
Abstract: PURPOSE:To provide a compact hot water generator which has a heat accumulating material improving a rise during production of hot water and having excellent heat response by a method wherein on-off valves are mounted both on the inflow side and the outflow side of a vaporizing part, and a heat accumulating material is located in a manner to be adhered to the outer periphery of the vaporizing part. CONSTITUTION:An electric heater 19 is energized to generate heat and a heat accumulating material 18 is heated to increase temperature. In this case, since, with on-off valves 16 and 17 closed, working fluid 14 in a liquid phase is left stored in a liquid reservoir part 15 and is not fed to a vaporizing part 1, a vaporizing part 1 is simply heated and not functioned as a heat pipe, resulting in execution of only accumulation of heat. Meanwhile, when the on-off valves 16 and 17 are opened in a state in which the temperature of the heat accumulating material 18 is sufficiently high, the working fluid 14 in a liquid phase is fed to the vaporizing part 1, for heating and vaporization. The steam flows through a steam pipe 4 to a zigzagging pipe 9 of an condensing part 3. During the passage of it through the condensing part, heat possessed by working fluid steam is imparted on feed water 2 flowing through a outer pipe 10. Since the heat capacity of a heat pipe is extremely low, a hot water generator having excellent heat response is provided.
