Abstract
Abstract A structure for mounting a bracket used to mount a heat exchanger 1 in which a plurality of tubes 9 are interposed between a pair of header pipes 2, 3 and a plurality of radiator fins 10 are interposed respectively between the tubes 9, or used to mount a pipe which is provided in such heat exchanger 1. In the structure, each of the header pipes 2, 3 includes a trough-shaped tank plate 5 in the outer side thereof and the tank plate 5 includes engagement means in the end portion thereof. A bracket 16 is mounted to the peripheral surface of the tank plate 5. The bracket 16 includes a pair of holding portions 17a, 18a which can hold therebetween the two end portions of the tank plate 5. Each of the holding portions 17a, 18a includes engagement means which is engageable or fittable with the engagement means in the tank plate 5.
