。In FIGS. 1 and 2, additional supports 6 are added in a U-shape at multiple locations (5 locations in FIG. 1) on the columnar body 1, for example by welding, and between the supports 6 and 5. Spiral tube 2,2.
2 (in Fig. 1, there are six tubes, but any number of tubes may be used as long as there are two or more). These supports 6, 5 are the first
Although it has a U-shape in the figure, it may be supported by a single support 31; You may write several words on the outer shell (see Figure 5). 1, this spiral tube 2°2.2
are in close contact with each other so that fluid, such as combustion gas, leaks from the gaps between the tubes, the gaps between the tubes and the columnar body, and the outer shell;
In addition, it is necessary to provide a width that is just enough to fit within the distance between the columnar body 1 and the outer shell 5 (FIG. 6). As will be explained later,
This is to allow the high temperature fluid, for example combustion gas, to flow in a helical manner and to make sufficient contact with the helical tubes 2, 2.2.

の燃焼を助長する。FIG. 6 shows an example of an instantaneous water heater incorporating the heat exchanger of FIG. A column 1 is placed which is provided with a helical tube 2, 2.2 supported by. In this case, the spiral tubes 2, 2.2 are tightly attached, and the structure is such that no fluid passes between the columnar body 1 and the outer shell 5, and the fluid flows spirally as shown by the arrow. and,
A plurality of gas burners 8 are installed on this bottom plate 7, and gas G is supplied thereto, and an air passage is formed by the outer shell 5 and the wall A, so that air is sent from the inlet 9 to the gas burners 8 in the direction of the arrow. It's okay. This facilitates combustion of the gas as heated air is passed through.

となるのである。In addition, in order to send a liquid, for example, water to the spiral pipes 2, 2.2, water W is sent to the water supply section 4 through a pipe P as shown in FIG.
The hot water enters the spiral tube 2゜2.
, 2.2, the water collects in the water supply section 4 (1, which becomes the drainage section 11), and is discharged from the pipe P. In a water heater, water W is first supplied to the water supply part 4, flows through the spiral pipe 2°2.2, and reaches the drainage part 11. When the gas G ignites the gas burner 8, this combustion gas is a spiral tube 2 as shown by the arrow
, 2.2, between which the spiral tube 2, 2
.. The water flowing through 2 and the high-temperature combustion residue exchange heat, and the water flowing into the drainage section 11 reaches a temperature of 80'' to 90° (nearly 2 degrees) and is drained and used. The gas is
It is discharged from the chimney 1 [] at a low temperature of about 50°C. In this way, since the contact area between the high temperature combustion gas and the spiral pipe is extremely large, the heat exchange rate between the combustion gas and the water flowing inside the spiral pipe is also large, and therefore the temperature of the heated and drained water also decreases. In addition, the exhaust combustion gas is also extremely low temperature.
なお・、第6図において、壁6f設けなくでもよいので
