20140037468 | GAS MICROPUMP - The micropump includes continuous cylindrical separating pipes having at least two alternating stages of pipes of small radius and large radius connected in succession. One end of the pipes constitutes a hot zone, and the opposite end constitutes a cold zone. The pipes alternate straight pipes with a large radius and U-shaped curved pipes with a small radius. The-relationship of the large radius of a straight pipe to the small radius (r) of a U-shaped pipe is in a range of R/r=2-10000, while the relationship of the temperature (T | 02-06-2014 |
