Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2017/135727
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat exchanger, which is a plate-type having a plurality of plates stacked and welded together, allowing material and processing costs to be reduced by decreasing the areas on which welding material is applied during production while assuring welding quality. The present invention comprises: a heat exchange part having heating medium channels, through which heating medium flows, and combustion gas channels, through which combustion gas burned in a burner flows, adjacently disposed in alternation in the spaces between the plurality of plates; a first welding part in which the outer edges of a pair of plates forming the heating medium channel are welded together; a second welding part in which the plates forming the combustion gas channel, between the plates forming the heating medium channel, are welded to the outer edges of the plates forming the heating medium channel to form; and a guide part for guiding the welding material molten solution of the first welding part into moving to the second welding part.
