| Don't get too excited about this - there are simple devices that have been known since about 1900 or even earlier that have an effective thermal conductivity over thousand times that of solid copper. They're known as 'heat pipes', and they consist of a hollow pipe sealed at both ends, and a liquid with a boiling point identical to the operating temperature of the heat pipe sealed inside. One end of the pipe touches the source (e.g. internal combustion engine), the other end the sink (e.g. radiator fins). Heat is absorbed at one end accompanied by phase transition (liquid-vapour), transfered to the other end by actual material transfer (e.g. convection), and heat is deposited there by phase transition (vapour-liquid). The liquid trickles back along the side of the wall of the heat pipe, or sometimes using a hydraulic pump assist (the latter version is used in all car cooling systems today).
The trick to system cooling is getting rid of the waste heat (by radiating it or recycling it somehow), and that's a *very hard* problem. It's relatively trivial to move it around from place to place within a system.
The new material doesn't change the system heat removal problem an iota - only half-baked engineers without a basic understanding of the laws of thermodynamics would make such a claim. Take it with a huge pinch of salt. | |
