PURPOSE:To effect heat exchange efficiently, by a method wherein a corrugated punching metal is mounted in a gap between the outer wall of a tubular filter of a resin, which includes a spring coil and the inner wall of a tube while a multitude of heat transfer filled with a hydrogenated metal is integrated closely. CONSTITUTION:Filters 11 of fluorine resin each of which is reinforced from the inside and includes a spring coil 12 are inserted into the heat transfer tube 1, while a corrugated punching metal 13 is mounted in the annular clearance between both and, further, the gap is filled with hydrogenated metal 10. Accord ingly, the heat transfer of the title heat exchanger is improved effectively by employing the inexpensive punching metal 13 while the expansion of the hydro genated metal 10 is absorbed by the filter 11 made of resin, therefore, the dam age of the heat exchanger may be avoided. Further, a multitude of heat transfer tubes 1 is integrated closely, therefore, the heat transfer coefficient of the title heat exchanger is increased by turbulent flow, whereby it is not only favourable in heat transfer but also effective in reducing heat loss. |
