Increasing of efficiency of air condenser with the help of cooling air distribution is
considered. The relevance of research connected with preservation of the compact sizes of the
heat exchange device is presented. The analysis of shortcomings of the existing designs on the
basis of the tubular heat exchanger with the short diffuser is carried out. Various devices and
recommendations about improvement of operation of the short diffuser are considered. The
research objective consisting in an assessment of influence of a configuration of flowing part of
the short diffuser on overall performance of the heat exchange device is formulated. The
methodology of carrying out the engineering analysis of cooling equipment on the base of
ANSYS CFX is developed. The calculation of tubular cooler characteristics with several
alternatives of the inlet section is made, the analysis of results from the point of view of losses of
pressure in the diffuser and amounts of the taken-away heat is carried out. The improvement in
cooler work using guide rails for its inlet section is discovered. |
