A heat exchanger includes fin cases each housing a pair of upper and lower fins. Each of the upper and lower fins has top and bottom portions. The upper and lower fins are oriented differently from each other such that first centerlines of the bottom portions of the upper fin intersect second centerlines of the top portions of the lower fin. The upper and lower fins are in contact with each other at locations where the first centerlines intersect the second centerlines. At these locations, the upper and lower fins support each other to strengthen the fin case such that the fin case bears loads applied to the fin case in a direction towards an inside of the fin case. The upper and lower fins have larger heat transfer area at locations where the fins are not in contact with each other. |
