Abstract
Thermal and pressure related fatigue or stress in the header plates (26, 28) of a charge air cooler is avoided in a structure wherein the header plates (26, 28) are formed of a channel having a central web (80) flanked by legs (82, 84) and provided with apertures (86) for receiving the ends of tubes (36). The apertures (86), on the side thereof between the legs (82, 84), are provided with peripheral flanges (88, 90, 92, 94) and on the opposite side are substantially surrounded by concave camming surfaces (96, 98).
