Abstract:
Heat exchanger for cooling semiconductor components, which comprises cooling fins that are spaced apart, attached to and projecting out from a base section of light metal, each fin being secured in a groove in the base section, wherein the cooling fins have a longitudinal axis and are in the form of cooling-fin plates made of thin-gauge strips of material and, in longitudinal cross-section, are profiled at least in the region where they join the base, wherein the grooves include flat regions parallel to the axis of the fins, wherein the cooling-fin plate is shared out of a sheet into a wavy form such that the distance transverse to the longitudinal axis (A) between two planes (E) defined by the wave peaks corresponds approximately to the width (i) of the grooves.
