Etymology

noun

1. Alternative spelling of heat sink

verb

1. (transitive) To fit with a heat sink.
   It was necessary to heatsink the device through the center conductor of the coax thereby producing a total thermal resistance from the active layer to the ambient of almost 50°C/watt. 1971, Joseph Stewart Bravman, Thermal effects in the operation of GaAs transferred electron microwave oscillators, page 138
   The device itself can dissipate a peak power of 78 W when properly heatsinked and has a 65 W steady dissipation. 2012, Robert B. Northrop, Analysis and Application of Analog Electronic Circuits to Biomedical Instrumentation, page 385
