Experimental research of horizontal air cooling apparatus

Abstract

The article considers horizontal air cooling apparatus (abbreviated - ACA), analyzes their shortcomings from the point of view of the gasdynamic imperfection of the flow part through the cooling air, suggests ways to solve this problem by installing special guides. To evaluate the proposed solutions, an experimental stand was designed and constructed, and experimental researches of ACA were conducted with three variants of the flow part. An increase in efficiency is achieved when installing concentric guides in part of a deeper lowering the temperature of the cooled stream and reducing the energy consumption of the fans. An economic evaluation of the proposal for the modernization of the flow part of the ACA has been carried out; a positive economic effect has been revealed from the use of guides.
