VÁNI, R. The Conception of Mini – heat Exchangers, Construction and Aplication. Ostrava: Department of Energy Engineering, Faculty of Mechanical Engineering, VŠB – Technical University of Ostrava, 2009, 43 pages, Bachelor Thesis, supervised: Kolat, P.

The bachelor thesis deals with questions of mini-heat exchangers, their description, their constructions and their aplications in chemical industry and in health service. The first chapter of this thesis is adressed to their clasifications in light of construction, including scheme of all particular mini-heat exchangers. The second chapter contains theoretical analysis and basic heat calculation of selected mini-heat exchanger. Transfer heat area is calculated in assist with basic equations of thermomechanics, for input temperatures and output temperatures of the warmed medium and of the cooled medium which were selected beforehand. The calculated values we compare with the original heat exchanger of the Exergy´s company. Values of transfer heat areas will be different because of using various coefficients in the theory and in the work experience, for example in the equation for calculation of Nusselt´s critery. The graphic part of thesis will be contain production drawing of mini-heat exchanger from Exergy´s company.
