摘要： The preset invention relates to a heat exchanger in which heat transfer between heating water passing through the inside of heat exchanging pipes and combustion gas is efficiently performed. The heat exchanger includes: a plurality of heat exchanging pipes, each of which has an end with an open flat tube-type cross-sectional surface, and through the inside of each of which heating water passes; a first fixing plate and a second fixing plate, each of which has pipe insertion holes formed at a predetermined spacing in the lengthwise direction of the plate, such that both ends of the plurality of heat exchanging pipes are inserted into the respective pipe insertion holes; a first parallel flow channel cap and a second parallel flow channel cap fixed at the respective first fixing plate and second fixing plate to close both ends of the heat exchanging pipes and thus form a parallel flow channel; a heating water inlet connected to the first parallel flow channel cap; and a heating water outlet connected to either the first or second parallel flow channel caps. The cross-section of each of the heat exchanging pipes has protrusions and recessions alternately arranged in the width direction of the heat exchanging pipe, so as to extend the flow path of the combustion gas passing through between the heat exchanging pipes.

摘要： The present invention relates to a method for braze-welding a fixing plate and a flow channel cap in a heat exchanger, and to a heat exchanger produced by same. The method comprises the step of: providing a fixing plate (10) having a plurality of resilient protrusions (11) for snap-fitting; providing a flow channel cap (20), one end (22) of which is L-shaped to be snap-fitted onto the resilient protrusion (11) and the other end of which has a stepped portion (21); inserting the stepped portion (21) of the flow channel cap (20) into the resilient protrusion (11) such that an end (21b) of the stepped portion (21) contacts an end of the resilient protrusion (11); pressing the L-shaped end (22) of the flow channel cap (20) against the resilient protrusion (11) of the fixing plate (10) such that the L-shaped end (22) is snap-fitted onto the resilient protrusion (11) and thus tightly contacts the fixing plate (10), and the resilient protrusion (11) thus press-contacts the end (21b) of the stepped portion (21) to enable an end (21a) of the stepped portion (21) to tightly contact the fixing plate (10); and braze-welding the fixing plate (10) and the flow channel cap (20). The above-described method eliminates a spot-welding process which might otherwise be performed prior to the process of braze-welding the fixing plate and the flow channel cap in conventional heat exchangers, to thereby reduce manufacturing costs and labor and to improve productivity.
