Abstract:
An element for dissipating heat generated by electronic components said element exposed to ambient air circulating by convection or other means comprising:a base member constructed to engage the component from which heat is to be dissipated in a thermally conductive manner; and aa plurality of pin members attached in thermally conductive relation to the base member and extending outward therefrom; each of the pin members having a longitudinal axis and a transverse dimension and further comprising:a root, at which the attachment to the base member occurs, said root having a first transverse dimension;a body, extending outward from the root and having a varying transverse dimension;a tip forming the outer end of the pin member a predetermined distance from the root, said tip having a second transverse dimension; andwherein the first transverse dimension is smaller than the second transverse dimension and the transverse dimension of the body expands continuously in a graduated manner from said first to said second, resulting in a smaller pin cross sectional area at the root than at the tip.
