Heat Sink
A heat sink is a basic but important cooling device used in electronic equipment like computers, gaming consoles, and other electronic devices. Think of it like a metal radiator that helps keep electronic parts from getting too hot. It's usually made of aluminum or copper and has multiple fins or ridges that help spread out heat. When someone lists heat sink experience on their resume, they're showing they know how to work with cooling systems in electronics, which is a valuable skill in repair and maintenance jobs.
