【 摘 要 】

This article is dedicated to the heat mass exchanger processes efficiency increase of circulating water cooling at chemical enterprises with development of a new design of a small-sized device of circulating water cooling with a swirling air stream. It is also proposed classification of constructions of small-sized towers on the main grounds. There is showed the relation for calculation of the time of phase interaction, from which it follows that the time of interaction of heat-exchanging phases more continuously in the device with swirling air stream, than in devices with contraflow. The indicator of the increase in the heat transfer coefficient, which shows how many times the difference of water temperature in inlet and in outlet of the swirling flow small-sized towers with is greater than the difference of water temperature in inlet and in outlet of mini cooling tower with contraflow.
