VORTEX AIR COOLER WITH PERMANENT REMOVING OF FROST Russian patent published in 2005 - IPC

FIELD: heat-exchange apparatus.

SUBSTANCE: air cooler comprises vortex heat exchangers, pipes of the vortex heat exchangers for flowing air to be cooled flows, swirlers, and actuator of purifying mechanisms. The actuator has hollow driving shaft mounted in the pipes and provided with a longitudinal groove throughout its length. The groove receives unmovable screw with a nut coupled with the bushing freely mounted on the shaft through a key. The brush holder with brushes are secured to the bushing. The outer side of the pipes of the vortex heat exchangers are provided with chutes for circulating a coolant. The vortex heat exchangers has a fining with a coefficient that varies according to the relationship where D is the diameter of the pipe, n is the number of chutes, and l is the chute width. The parameters vary in the following range: D = 50-800 mm and l = 20-50 mm. The chute height l₁ =3-40 mm, the thickness of the pipe wall and the thickness of the chute wall

EFFECT: simplified structure and enhanced reliability.
