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 Electronics, computer, LED, Power Transistor, Power Amplifier, Voltage Regulator, etc.
