  • Cooling element for electronic components
    Patent number: 5893409
    Abstract: A heat sink for electronic components is presented, which is integral and comprises a strip of sheet brass. This strip is bent in a meandering shape, contact surfaces being seated on a heat distributor of a component, in the region of lower meandering curves. The heat sink is held firmly on the component by means of an internally produced prestress in conjunction with a snap-action connection. Although the heat sink has longitudinal elasticity even in the fitted state, its heat-dissipating function can always be maintained.
