Parts List for Ranque-Hilsch Effect Tube
1/2" copper piping, cut into two lengths: 1 m and 25 cm. Why does it look like the long one is more than 1 m? I dunno. Maybe I hadn't cut it yet.
I used these lengths because Hilsch (see reference on main page) says that the long run should be 50 times the diameter of the piping. I used 1/2" piping, and that told me to use about 64 cm. I then added more length for the purposes of overkill (piping is cheap).
- One 1/2" sweat-to-thread (male) coupling. The term "sweat" means solder. e.g., he made a sweat (solder) connection.
- One washer - 3/4" O.D., 6.5 mm I.D. (sorry for the mixed units)
- One 1/2" re-makeable threaded coupling (sweat to pipe at both ends). The lint on the floor is not part of the design.
- 1/4" O.D. (1/8" I.D.) copper tubing. Length does not matter. I used a 7" piece.
- One compressed air quick-connector. Shown here already connected to tubing.
- Also, one compression fitting for attaching the quick-connector to the tubing. You just tighten it on with wrenches.
- An air compressor. I used my dad's.
