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. |
