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).

Aluminum charge air cooler and method of making the same

In order to eliminate components and fixtures, facilitate assembly, avoid leaks, and reduce cost in a heat exchanger for exchanging heat between two fluids such as a coolant and oil, the heat exchanger includes a header plate having a central opening defined by a column integrally formed with the header plate together with a radial opening. A plurality of heat exchange units are stacked on the header plate. The heat exchange units each comprise a pair of plates joined together at inner and outer peripheral edges to thereby sealingly define a plurality of first chambers for the flow of one of the fluids wherein a column-receiving opening is provided radially inwardly of the first chambers thereof. The heat exchange units further include aligned first openings and aligned second openings on opposite sides of the column-receiving openings for joining the first chambers in a first fluid flow path, and the radial opening in the header plate comprises a first fluid inlet for directing the first fluid through one of the first openings into the first fluid flow path where it flows until it reaches a first fluid outlet therefor. The heat exchange units are stacked on the header plate about the column where they are arranged in a spaced series by spacers which serve to define a plurality of second chambers for the flow of the second fluid between each pair of the spaced series of heat exchange units.
