CONDENSATION HEAT EXCHANGER HAVING DUMMY PIPE

摘要

A condensation heat exchanger having dummy pipes is provided in which a plurality of condensation heat exchange pipes are connected by means of water housings so as to recover latent heat while the water is circulating, and, by having the dummy pipes, penetrating the water housings, arranged in between the condensation heat exchange pipes, the pressure applied to the water housings is distributed and smooth flow of water is facilitated.

主权项

1. A condensation heat exchanger comprising:
a body section (110) surrounded by side plates while being opened at upper and lower portions thereof; a plurality of heat exchange pipes (120) closely arranged between opposite side plates of the body section while passing therethrough, with a gap through which a hot combustion gas passes; a plurality of water housings (130) assembled to outer surfaces of the opposite side plates of the body section (110) and configured to connect the heat exchange pipes (120) together so that water flows through the heat exchange pipes (120); and a dummy pipe (140) arranged among the heat exchange pipes (120) while passing through both the opposite side plates of the body section (110) and the water housings attached to the outer surfaces thereof.
