DC motor chlazený tepelnou trubicí
Vlach, Radek
This project is concerned with non-convectional DC machine rotor cooling using heat pipe in the shaft. The aim was created computational model using finite elements method. The thermal model was built in software ANSYS. Experimental measuring was used for verification of computational simulations.

New Approach of electric machine Winding Water Cooling
Vlach, Radek ; Krejčí, Petr ; Grepl, Robert
Summary: The paper is concerned with new conception of direct winding slot water cooling. The heat flow from winding slot to frame is very complicated. The new approach solves transfer heat losses direct from winding slots. The special structure of brass tubes will be placed in the winding slot. Computational simulation of new cooling system concept is realized by using CFD analyze. Software FLUENT was used for computational simulation of water cooling drive.

Chlazení vinutí synchronního motoru s využitím tepelné trubice
Vlach, Radek ; Ondrůšek, Č.
The paper is concerned with computational simulation of stator winding heating of synchronous machine. Software ANSYS 6.1 was used for computational modeling. Computational model consider heat pipe in the middle of winding slot. The results of computer simulation show effect of heat pipe on winding cooling. Other results show effect of heat pipe position and size of cooling surface on winding heating.
