Abstract

A crimping frame or crimping base for a charge air cooler may include a circumferential raised rim including a plurality of crimping slots. The plurality of crimping slots may each include two longitudinal sides and two narrow sides. The two longitudinal sides may be disposed opposite one another and may extend parallel to the rim. The two narrow sides may be stiffened via a bent reinforcement. The bent reinforcement and the rim may be structured as a single piece.
