FIG. 1 shows the configuration of a separate heat pipe that has been conventionally used as an example of a heat exchanger. This is done by arranging a plurality of evaporation tubes 2 within the evaporation section 1, and connecting the upper and lower ends of the plurality of evaporation tubes 2 to an upper header 3a and a lower header 3b, respectively, so as to intersect with the gas flow. In addition, a plurality of condensing pipes 5 are installed in the condensing section 4.
The upper and lower ends of the plurality of condensing pipes 5 are connected to the upper header 6a and the lower header 6b, respectively, so as to intersect with the low temperature gas flow, and the upper header 3
a and 6a are connected to each other by a steam communication pipe 7, and lower headers 3b and 6b are connected to each other by a condensate communication pipe 8, and a thermal fluid such as water is sealed in the above-mentioned paths. With this configuration, the vapor of the working fluid evaporated in the evaporator tube 2 is introduced into the condenser tube 5, and heat is exchanged by condensing the heat.

欠点があつた。 However, in recent years, there has been a need to improve the heat exchange rate and save energy due to the demands of the times. Since the piping must be placed in the remaining space, the piping itself becomes long and extremely complex, with some U-shaped bends. When the piping becomes U-shaped like this,
Condensate builds up there, blocking the steam and causing the heat pipe to lose its function. In addition, in a separate type heat pipe, since steam may condense in the steam communication pipe 7, the effective cross-sectional area of the steam communication pipe 7 becomes narrow, and the steam also absorbs the condensed working fluid. There was a drawback that the resistance in the steam communication pipe 7 was increased by the removal, and the flow was worsened. Also, even if a separate type heat pipe is newly installed, the boiler etc.
Drainage tends to occur due to load fluctuations on the heating side, particularly during startup, and in this case, the steam communication pipe 7 is closed, or even if it is not closed, there is a drawback that the steam flow resistance becomes large.

The present invention will be explained below based on the drawings. FIG. 2 shows a configuration diagram of an embodiment of the present invention. In the following figures, the same or equivalent parts as in FIG. 1 are given the same reference numerals. In this embodiment, the vapor of the working fluid generated in the evaporating section 1 is guided to the condensing section 4 through the steam communication pipe 7, and heat is given to the medium to be heated, where it is condensed by heat radiation and becomes a working fluid, as in the conventional example. , In the circulation path that passes through the condensate communication pipe 8 and returns to the evaporation section 1, a drain communication pipe 9 is provided between the steam communication pipe 7 and the condensate communication pipe 8, so that the vapor communication Only the drain generated in the pipe 7 is allowed to flow out into the condensate communication pipe 8.

With this configuration, when the condensate in the vapor-liquid mixture is discharged by the pressure reducing valve 10 and the condensate overflows from the U-shaped pipe 11, it is transferred to the condensate communication pipe 8 through the overflow pipe 13. Bypassed. In this case, by filling the U-shaped pipe 11 with a working fluid such as water as described above, micro-pressure steam will not flow into the condensate communication pipe 8. The blow valve 12 is used when the pressure reducing valve 10 and the blow valve 12 are fully opened and discharged to the atmosphere in order to blow away rust etc. from the piping system at the beginning of operation and as needed. The height H of the working fluid inside the U-shaped tube 11 is set as follows. In other words, the working fluid pressure P H becomes greater than the pressure difference (P 1 - P 2 ) between the pressure P 1 in the steam communication pipe 7 and the pressure P 2 on the condensate communication pipe 8 side reduced by the pressure reducing valve 10 .
