ABSTRACT:
To provide a heat exchanger capable of installing the side plate to the header pipe accurately without improper joining and errors respectively is disclosed. In a heat exchanger in which both end portions of the side plate are inserted into end portions of a pair of header pipes respectively, a large number of tubes are provided between the header pipes between the side plates, and fins are provided between the large number of tubes, a pair of pawls for pinching the header pipe wall therebetween are provided on both sides of both end portions of the side plates respectively so that the pair of pawls regulate the angle of installation and the insertion position of the side plate to the header pipe. This enables the side plate to be accurately installed to the header pipes in a state free from improper joining and errors, and the header pipes are accurately positioned, thus eliminating any possibility of causing obstruction to piping or the like.
