The used principles of industrial cooling
Machala, Jiří ; Sekanina, Bohumil (referee) ; Kavička, František (advisor)
This thesis summarizes the main cooling methods used in industrial cooling systems. It also discusses the fluids used in cooling, their influence on environment; ozone layer and climate change. The thesis closely describes the properties of ammonia and out of the many cooling methods on the market, it mostly concentrates on ammonia cooling systems. The thesis also discusses heat pumps, vortex tubes, and thermoelectric cooling.

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.
