Abstract
A heat sink for CPUs for use in personal computers comprises a radiating base plate of metal having on one surface thereof a flat portion for receiving the heat generated by the CPU, and a plurality of raised radiating fins integrally formed by cutting on the other surface of the radiating base plate. The heat sink can be provided with a greater number of radiating fins than a conventional heat sink of comparable base plate size, hence an increased radiating area is obtained.
