Toplotni kontrolni elementi

Fluidno toplotno stikalo

Kratek opis

Toplotni kontrolni elementi mogočajo nadzorovanje toplotnega toka, rektifikacijo toplote in gradnjo toplotnih tokokrogov.
Implementirajo se na področjih senzorjev, lab-on-chip napravah, v mikrofluidiki, v napravah za pretvorbo energije, itd.

Obseg našega dela

Implementacija toplotnih stikal v kaloričnih napravah
Numerična in parametrična analiza makroskopskih toplotnih diod

Toplotna stikala, toplotne diode, toplotni regulatorji

Predvsem v elektroniki se pojavljajo težave zaradi nezmožnosti odvoda toplote z elektronskih komponent preko konvencionalnih načinov (z razširjenimi površinami in vsiljeno konvekcijo). Toplotni kontrolni elementi ponujajo popolnoma nove dimenzije nadzorovanja toplotnega toka v različnih aplikacijah. Najbolj pomembni elementi (ki so analogni električnim elementom), so toplotno stikalo, toplotna dioda, toplotni reulator, toplotni tranzistor. V analogiji z električnimi tokokrogi, lahko z njimi gradimo toplotne tokokroge.

Toplotni kontrolni elementi se trenutno uporabljajo npr. v napravah za pretvorbo energije, v senzorjih, v mikrofluidiki in v lab-on-chip napravah.
