Thermoacoustic Refrigerator

This is my thermoacoustic refrigerator! It is a device that uses a resonating sound wave to induce a thermal gradient. I built this as part of my senior design project at the University of Portland back in 2006.

Hi, you gave a great explanation! I have a few questions though:

- Is the length of you resonator 1/4 or 1/2 of the wavelength?

- I imagined that with your configuration you would have placed the stack at the 3/4th of the length of the resonator (starting from the left), but it seems you placed it around 1/3rd. Why is that?

China has large thermoacoustic refrigerator in the market since 5 years ago, very economic refer,

not expensive i recalled. size is not small though

is the most usefull explanation of how a thermoacoustic effect works... Congratulations my friend, I hope you are not wasting yourself working for a big and good reputation international company for low paycheck... Make your own company and get rich... but you need to develop bussines knowledge, geek required knowledge you already have. can you please explain me more about the heat exchangers at the ends of the stack?
