Title:
LATENT-HEAT EXCHANGER HAVING MULTIPLE FLOW CHANNELS FOR HOT-WATER HEATING AND CONDENSING GAS BOILER INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2015/141991
Kind Code:
A1
Abstract:
The present invention relates to a latent-heat exchanger having multiple flow channels for hot-water heating and a condensing gas boiler including the same. The condensing gas boiler comprises a sensible-heat exchanger and a latent-heat exchanger that heat circulating heating water using combustion gas caused by the ignition and combustion of a burner, wherein the latent-heat exchanger includes: a plurality of circulating-heating-water heat exchange units having a circulating-heating-water flow channel formed therein through which circulating heating water flows; and a plurality of direct-water heat exchange units having a direct-water flow channel formed therein through which direct water flows, wherein the circulating-heating-water heat exchange units and the direct-water heat exchange units are alternately disposed, and a combustion gas flow channel through which combustion gas flows is formed between the circulating-heating-water heat exchange units and the direct-water heat exchange units.
