A very nerdy idea
Posted on Friday, February 29th, 2008 at 11:44 am by Jeff HoyA Stirling engine powered fan and heatsink for a motherboard chipset you say? Now that is hardcore nerd stuff right there.
The “Air Power Cooler” transfers the chipset heat into air momentum, when the air becomes hot, the air will expand then push the fan to rotate and In doing so cooling the heatsink immediately. After the air moves from the bottom to top of the piston, the air will become heavy to push the up piston down. The better air piston design can transfer over 70% heat power and transfer to air power, that’s great efficiency transfer from Stirling engine theory. In a comparison with solar power the transfer rate is only around 20~30% requiring more surface and as a result cost.
I’d like to see a video of it in action and perhaps a cooling ability comparison with a normal dc electric fan.
