PURPOSE:To make the temperature gradient for fins moderate, by determining the position of one pipe of a pair of pipes through which one heating medium passes in the position of another pipe in the neighboring pair of pipes in regard to the flowing direction of combustion gas, in pairs of pipes through which heating mediums of different purposes pass, respectively, in the titled heat exchanger. CONSTITUTION:Pipes 2 and 3 are combined in a pair, disposed in the upper and the lower positions, and a pair of the two pipes is located in the position in a combustion gas passage. The pipes are arranged in such a manner that, when a heating pipe 2 is located on the upstream side of a pair of pipes 2 and 3, the pipe 2 in the neighboring pair is located on the downstream side, while in the next pair, the pipe 2 is positioned in the reverse side again. Accordingly U- shaped bents 4 and 5 are located slanting. By circulating feed hot-water through the pipes 3, heat can be transferred to a fin 1, and the temperature is unified if there is the difference in the temperature between the pipes 2 and 3, so that durability of the pipes can be increased. |
