Test bend for vehicle air-conditioning testing
Andrýs, Jan ; Hejčík, Jiří (referee) ; Štětina, Josef (advisor)
The aim of this work was to design test bend for vehicle air-conditioning. This test bend should simulate interior of the car and the engine compartment. Electric motor is used to drive compressor in test bend. Air supplied to test bend is modified to extreme conditions and the volume of supplied air is the same as the car drove at 50 km/h. Main frame of test bend is made from aluminium profiles manufactured by Bosch Rexroth, which provides great modularity. Walls are made from insulated panels by ELCOM System, they have very good insulation and are strong so additional equipment can be installed inside. Construction design was made is SolidWorks with 3D models of test bend as output. Air-conditong parts which were used as samples are originally from Skoda Octavia II. For this vehicle were made calculations of heat loads. In conclusion is simple testing example for this test bend and although there are some examples for future measuring.

Applying SolidWorks Flow Simulation for cooling system of the power converter
Matoušek, Patrik ; Vetiška, Vojtěch (referee) ; Dostál, Lukáš (advisor)
Thesis deals with the issue of cooling power converters. It describes the disposition of power converter M50, produced by ELCOM, a.s., and the distribution and origin of heat losses in the converter. The thesis then describes the process of creating a 3D CAD model of the converter in Solidworks and the procedure for heat simulation of the converter in default state and with cooling fan failures using Solidworks Flow Simulation. The thesis then evaluates the results of these simulations, and on their basis it suggests possible improvements in the design of converter‘s cooling system. These improvements are then evaluated in further simulations. The thesis then describes the verification of performed simulations by comparison with a temperature-rise test.
