Improvement of manufacturing technology of flange
Dvořák, Jakub ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This diploma thesis focuses on improvement of the existing technology of the flange part in cooperation with the company Znojemské strojírny, s r.o. The theoretical part describes the technologies used in machining of the component. Subsequently, cutting materials and aluminum alloys are dealt with. A detailed analysis of the existing technology is performed in the practical part of the thesis followed by rationalization of the production process, which was carried out with respect to time and financial savings. A new technological procedure is developed after the improvement of the current production process. Finally, a technical-economic evaluation of the design improvement process is carried out.

Dvořák, Jakub ; Bělka, Miloslav (referee) ; Jaroš, Michal (advisor)
The aim of this bachelor’s thesis is to compile summary of heat exchangers manufacturers, which occurs on Czech market. In the theoretical part of this thesis is stated distribution of heat exchangers according to some basic criterions (for example flow arrangement). This distribution is followed by short explanation of how heat transfer can be realized. In the end of the theoretical part of this thesis there are presented some physical relations and their description. More practical and main part of this bachelor’s thesis contains summary of heat exchangers manufacturers and examples of their products, which are divided to some categories, mainly according to construction. At the end, there is comparison of brazed plate heat exchangers from various companies in application for preparation of hot water.
