<p>PROBLEM TO BE SOLVED: To maintain desired heat exchange performance by suppressing deformation of a fin in a heat exchanger.SOLUTION: In a fin 18 constituting a heat exchanger 10, a plurality of inlet louvers 30 and outlet louvers 32 are formed along a flow direction F of air passing through the heat exchanger 10, adjacent two inlet louvers 30 on the uppermost stream side are connected by a first connecting wall 34, and adjacent two outlet louvers 32 on the lowermost stream side are connected by a second connecting wall 36. Thus, strength on both ends of the fin 18 on the upstream side and the downstream side in the flow direction F of the air passing through the heat exchanger 10 can be enhanced, deformation when a flying stone hits while the heat exchanger 10 is mounted on a vehicle can be restrained, and deterioration of heat exchange performance caused by the deformation can be suitably prevented.</p> |
