Copper heatsink is a popular thermal management option among electronic devices because of its capacity to absorb heat relatively quickly.
Made of pure copper , the thermal conductivity up to 401W/(mK.). Copper heat sinks has nearly double the thermal conductivity than aluminum.
It is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to air, where it is dissipated away from the device, thereby allowing regulation of the device's temperature.
Widely used for Electronic, Chip, Computer 's component, etc.
