LATENT-HEAT EXCHANGER FOR HOT-WATER HEATING AND CONDENSING GAS BOILER INCLUDING SAME

摘要

A latent-heat exchanger comprising an upper heat exchange unit in which a plurality of circulating-heating-water heat exchange units having a circulating-heating-water flow channel formed therein and a lower heat exchange unit disposed on the lower side of the upper heat exchange unit, in which a plurality of direct-water heat exchange units having a direct-water flow channel formed therein is provided.

主权项

1. A latent-heat exchanger for hot-water heating, which heats circulating heating water using combustion gas generated due to ignition and combustion of a burner, comprising:
an upper heat exchange unit including a plurality of circulating-heating-water heat exchange units and a combustion gas flow channel, wherein the circulating-heating-water heat exchange units are arranged to be adjacent to each other and connected to each other and a circulating-heating-water flow channel is formed therein to allow circulating heating water to move therethrough, and the combustion gas flow channel is formed between each of the circulating-heating-water heat exchange units to allow combustion gas to move therethrough; and a lower heat exchange unit located below the upper heat exchange unit and including a plurality of direct-water heat exchange units and a combustion gas flow channel, wherein the direct-water heat exchange units are arranged to be adjacent to each other and connected to each other and a direct-water flow channel is formed therein to allow direct water to move therethrough, and the combustion gas flow channel is formed between each of the direct-water heat exchange units to allow the combustion gas to move therethrough.
