Copper graphene based technology to cool electronic gadgets more efficiently

Advanced methods to dissipate heat from electronic gadgets are enormously important. A gadget with overheat means it may either dawdle or halt functioning at anytime. A researcher at the North Carolina State University has worked out a highly efficient and low-cost method to cool electronics devices easily. The technology will help an overheating device like a laser or a power device cool down quickly.

Most efficient way to cool devices

Dr. Jag Kasichainula of the NC State University, has worked behind the breakthrough invention. The new technology, that he names a heat-spreader, utilizes copper graphene, which needs to be connected with the particular electronic gadget in help of an interface film of indium graphene.

The researcher takes advantage of the high thermal conductivity of the copper graphene and indium graphene to let the devices cool down efficiently. Thermal conductivity means the rate at which some materials could conduct temperature. Therefore, the technology that ingeniously makes use of copper graphene and indium graphene can avert overheating of devices.

The researcher claims that the thermal conductivity of copper graphene film can cool a device 25 percent faster than a pure copper. In current devices, pure copper is used for the purpose. That means installation of the copper graphene film will significantly boost the efficiency of the device against overheat.

The paper from the researcher also elaborates the way to produce the copper graphene composite. It is developed through an electrochemical deposition process. What makes the material special is its low cost factor. Copper with graphene has less cost when compared to the cost of pure copper, the researcher claims.
