PURPOSE:To contrive to improve the heat transmission performance of the titled device by method wherein the smooth recovery of working liquid to a generator is realized and at the same time the difference between the pressure at the generator and that at a liquid receiver tank is made smaller in a non-powered heat transmission device such as employed in a solar water heater or the like. CONSTITUTION:The titled heat transmission device consists in connecting a steam tank 13 by a communicating pipe 14 with the top part of an upper header 2 and a heat exchanger 6 by a flow pipe 8 with the bottom part of the upper header 2 in a generator comprising a plurality of heat exchanger pipes, the upper ends of which are communicated with one another by the upper header 2 and the lower ends of which are communicated with one another by a lower header 3. Accordingly, working liquid evaporated at boil in the pipes 1 goes under two phase state or steam-liquid state to the upper header 2, resulting in separating into steam, which is led to the top part of the header 2, and liquid, which is led to the bottom part of the header 2. Consequently, because only the steam is further led by the communicating pipe 14 to the steam tank 13, the pressure in the header 2 is led to a liquid receiver tank 10, resulting in realizing good recovery of the working liquid. In addition, because only the liquid is sent through a flow pipe 8 and a heat exchanger 6 to the liquid receiver tank 10, the difference between the pressure at the header 2 and the pressure at the tank 10 becomes smaller. |
