SEGMENTAL BAFFLES AS A MEANS OF IMPROVING THE HEAT TRANSFER EFFICIENCY OF AIR COOLERS

摘要

A comparative analysis of the main types of air coolers (ACs) is presented. Their advantages and disadvantages are indicated along with the main approaches for increasing heat removal efficiency. In order to intensify heat transfer without substantially raising equipment costs or significantly altering production processes, the authors propose a technological solution based on a calculation that ensures a theoretically optimal counter-flow phase interaction scheme by equipping a horizontal AC with segmental baffles. This technological solution is shown to increase the heat transfer coefficient, leading to a reduction in energy consumption, the area of the required heat transfer surface, as well as the overall weight and size of ACs.
