Title:
Latent heat exchanger for hot water heating and condensin gas boiler including it
Document Type and Number:
Japanese Patent JP6291590
Kind Code:
B2
Abstract:
The present invention relates to a latent-heat exchanger for hot-water heating and a condensing gas boiler including the same. The latent-heat exchanger for hot-water heating, which heats circulating heating water using combustion gas caused by the ignition and combustion of a burner, comprises: 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 through which circulating heating water flows are connected to be disposed adjacent to each other, and a combustion gas flow channel through which combustion gas flows is formed between the circulating-heating-water heat exchange units; 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 through which direct water flows are connected to be disposed adjacent to each other, and a combustion gas flow channel through which combustion gas flows is formed between the direct-water heat exchange units.
