1. A cooling apparatus for a heat generating device comprising:

  • a substrate, on which is mounted said heat generating device;

    a heatsink including a convex arcuate surface, said arcuate surface curved along a single axis, the profile of said convex arcuate surface defined by the following equation;

    
    
    space="preserve" listing-type="equation">Y=P * C * (X/L-(2 * (X.sup.3 /L.sup.3))+X.sup.4 /L.sup.4) where;

    P=a uniformly distributed load along the length L of said convex arcuate surface of said heatsink;

    C=the flexural stiffness constant of said substrate;

    L=the length of said convex arcuate surface of said heatsink;

    X and Y=coordinates defining the curve with respect to a two-dimensional Cartesian coordinate system having an origin on said convex arcuate surface; and

    means for maintaining said substrate in close contact with said arcuate surface of said heatsink.
