METHOD FOR INCREASING AERODYNAMIC EFFICIENCY OF AIR COOLING DEVICES AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC F28D1/02 

FIELD: physics.

SUBSTANCE: invention relates to a method of increasing aerodynamic efficiency of air cooling devices (ACD) and device for its implementation, that is to ACD used for cooling natural gas compressor stations of main gas pipelines, and can be used in them, thereby significantly increasing their aerodynamic efficiency. Method for increasing aerodynamic efficiency of air cooling apparatus includes supplying cooling air in contact with suction surface, to inlet of collector of suction surface due to rarefaction created by blades of fan impellers, which convert mechanical energy of their rotation into potential and kinetic energy of cooling air movement through collectors of suction surface into fan housings, diffusers, and further to heat exchange sections formed by bundles of finned tubes with cooled gas moved therethrough, enthalpy of which is reduced as a result of heat transfer from gas to air. At that, cooling air velocity at suction surface collectors is equal to its speed at heat exchange sections. Also disclosed is an air cooling apparatus which realizes the method according to the invention.

EFFECT: invention increases aerodynamic efficiency of ACD.
