Heat exchangers such as charge air cooler can fail due to thermal strain. At that time, we can use FEA and estimate loading stress. But it is not possible modeling of whole detailed structure for charge air cooler, because plate-fin structure of charge air cooler is complex. So, because plate-fin structure is periodic, homogenization method can be applied. There we focusing on fin shape, we try homogenization analysis for the various shape of fin (real and designed shape), and compare experiment. As a result, real shape of fin is consistent with experiment. Thus, when we apply homogenization method for plate-fin structure, we should use real shape of fin and make the whole product model.
