Cooling of Laptops - It it possible to use copper pipe and heat convection to achieve this?? Answered
I have a compaq laptop that runs the cpu at 55 °C which is equal to 130 - +°F. I have constructed a fan extraction system using my computer desk that has two fans underneath extracting the hot air from the bottom of the laptop unit and 2 fans directing cool air into the laptop from behind. I am only getting a 5C temperature drop. That is when the computer is idle. If the computer is actively processing this temperature goes up. The core temperature is constant 4 degrees high the cpu.
I have read that using a hot water bottle is an effective way of reducing the temperature. I actually tried this method and it gave me much the same result as the fans. see this site http://digitalcomposting.wordpress.com/2008/04/30/water-cooled-laptop-stand-6/
Has anyone tinkered with the notion of using a sealed copper coiled tubing with water or coolant. That the laptop can sit on via a thin aluminum plate as its base and acting as a heat transference agent then using the natural heat convection en.wikipedia.org/wiki/Heat_transfer to cool the laptop. This is achieved by having one of the sealed ends of the copper tube immersed into cold liquid. The convection would presumably happen due to the heat and cold differences. Your opinions and further Ideas are welcome.
