Abstract
The present subject matter includes: 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.
Claims9
A heat exchanger comprising:
- a plurality of plates;
- and
- a heat exchange part in which a heating medium channel (P1), through which a heating medium flows, and a combustion gas channel (P2), through which a combustion gas combusted in a burner flows, are alternately formed adjacent to each other in a space between the plurality of plates,
- wherein edges of a pair of plates forming the heating medium channel (P1) among the plurality of plates are weld-coupled to form a first welding part (W1),
- edges of a pair of plates forming the combustion gas channel (P2) among the plurality of plates are weld-coupled to form a second welding part (W2), the pair of plates forming the combustion gas channel (P2) being a first plate and a second plate, and
- a guide part is formed to guide a molten solution of a welding material of the first welding part (W1) to be movable to the second welding part (W2),
- wherein the guide part includes:
- a convex portion (132) convexly protruding outward from an edge of the first plate, which is disposed at one side and forms the heating medium channel (P1);
- and
- a concave portion (162) recessed inward from an edge of the second plate, which is disposed at the other side and forms the heating medium channel (P1), partially overlapping with the convex portion (132), and forming a gap to allow the molten solution of the welding material to be movable,
- wherein a plurality of convex portions (132) are formed along the edge of the first plate at predetermined intervals, and a plurality of concave portions (162) are formed along the edge of the second plate at predetermined intervals.
