Abstract
A heat exchanger has tubes inserted in headers easily to a given depth, and also has brackets which are readily attached to the headers. Each of the headers (3, 4) is divided into an inner half (5) and an outer half (6) facing the inner half in which apertures (5a) for receiving ends of the tubes are formed. The bracket (12) having a fastenable rib (12c) is fitted on the header over its halves (5, 6) so that these halves are made immovable relative to each other. Alternatively, the outer half (6) of the header may have a pair of embracing portions (12a) which fit on lateral sides of the inner half (5) so as to hold it in place.
