A heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device, thereby allowing regulation of the device's temperature at optimal In computers, heat sinks are used to processing units or graphics processors. Heat sinks are used with high-power semiconductor devices, where the heat dissipation ability of the component itself is insufficient to moderate its temperature. Features - Color: Silver. - Material: Aluminum. - Size: 1.50 x 1.50 x 0.50cm/ 0.59 x 0.59 x 0.20 inch. - The small aluminum heatsink is designed to maximize its surface area in contacts with the cool air. - Made of high quantity aluminum, the small aluminum heatsink is of good thermal conductivity. - The small aluminum heatsink is of glue on the back, so that can be easily stick to hardwares. - The small aluminum heatsink is widely used for computer, power IC, power electric device, LED light devices, etc. - The small aluminum heatsink is of light weight, and used in applications where weight is a big concern.
