Abstract:
1. A heatsink comprising: a thermally conductive body including a plurality of fins configured to conduct and dissipate heat, the body being configured to receive a circuit board containing a plurality of heat-producing electrical components along a width of the body; a pivot mechanism pivotally coupled to the body and configured and disposed to contact the plurality of heat-producing electrical components; and a bias device connected to the body and the pivot mechanism and configured to change from a first state to a second state to cause the pivot mechanism to rotate relative to the body to move a contact portion of the pivot mechanism toward the body; the heatsink being configured to receive the heat-producing electrical components between the contact portion of the pivot mechanism and the body; the bias device being configured to bias the contact portion of the pivot mechanism to urge the heat-producing electrical components against the body when the bias device is in the second state; and wherein the bias device comprises a first member pivotally coupled to a second member, the first member pivotally coupled to the body at a first pivot point, the second member pivotally coupled to the pivot arm at a second pivot point, and a combined length of the first and second members is greater than a distance between the first and second pivot points when the bias device is in the first state.
