Abstract

PURPOSE: To prevent the mixing of liquids even when a hole is made in a wall by a method wherein two metal pipes are wound in plural times spirally, touching each other and being lined in parallel and are formed into a disc having two passages for liquid.
CONSTITUTION: Two oval metallic pipes 4 and 5, being lined in parallel so that the wall surfaces thereof touch each other, are wound spirally in plural times and formed into a disc. The pipes thus formed are given an outer force shown by an arrow F so that the oval sections thereof are transformed into the shape of square, thereby the area for heat transmission being enlarged. By forming the pipes in this way, the liquids flowing through two passages C and D do not mix with each other even when corrosion or the like makes a hole in one wall, which makes safe even the heat exchange of the noxious liquid is performed. In addition, since both left and right sides of pipes become heat-transmitting surfaces, the area for heat transmission is enlarged and also the device can be made compact.
