20.500.12556/RUL-92941 Povečanje učinkovitosti prenosa toplote v kompleksni strukturi uparjalnika Increasing the efficiency of heat transfer in a complex evaporator structure Magistrsko delo obravnava prenos toplote v kompleksni strukturi cevno-ploščnega uparjalnika, ki se uporablja v gospodinjskih hladilnikih. V prvem delu je predstavljen analitični model za popis porazdelitve temperatur, toplotnih tokov in toplotnih upornosti v strukturi uparjalnika. Analitični rezultati so primerjani z numerično simulacijo. V drugem delu so predstavljene ideje in rezultati iskanja novih konstrukcijskih rešitev za povečanje učinkovitosti prenosa toplote. Ideje so vrednotene glede na njihov vpliv na toplotni tok, tehnično izvedljivost in stroškovno upravičenost. The topic of this thesis is heat transfer in the complex structure of a hot-wall evaporator, used in household refrigerators. An analytical model for describing temperature, heat flow and thermal resistance distribution in a hot wall evaporator structure, of a household refrigerator, is presented in the first part of this thesis. Analytical results are compared with a numerical simulation. Ideas and results of possible design improvements, for increased heat transfer in the evaporator structure, are presented in the second part of this thesis. They are evaluated by their influence on heat flow increase, technical feasibility and costs. uparjalnik prenos toplote učinkovitost prenosnik toplote hlajenje evaporator heat transfer efficiency heat exchanger refrigeration true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-07-11 09:19:59 2017-07-11 09:20:00 2023-11-29 09:44:36 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 189581 438.pdf 438.pdf 1 F00CDF063FDEC4B388EEDD789FD31DE6 016b252334ef91f92ceb7cd3fbf947b2dcab6a164b87ee700085d5ee58b92cc2 7684ad57-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/2f73ab0d-7e71-435b-9e46-44a442752096 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=101107 Fakulteta za strojništvo 0 0 0
