Abstract

Fall-f ilmfordaniper med oppvarmingselementer (10 og 11) Anordnet generelt parallelt 1 forhold til hverandre med motstående overflater til tilliggende elementer, som definerer vertikale kanaler som tillater strøm av væskeformet kjølemiddel nedover overflatene til elementene (10, 11) som en fallende film. Elementene (10) innbefatter en gruppe med elementer som er under en hette (12), som er i form av en boks med en topp. (13) og sidevegger (14). De øvre endene til plateelementene (10) er omgitt av sideveggene (14) til hetten (12), som har en åpen hunn og som tillater fri passasje av damp fra inne i hetten (12) til det Indre rommet av fordamperhuset (som ikke er vist på fig. 1 for å vise de andre delene nærmere). Direkte over elementene (10) inne i hetten (12) er det anordnet et væskefordelingstrau (15). Bunnen til trauet (15) har huller som tillater væske å passere fra trauet (15) til overflaten av plateelementene (10) under trauet (15). Hetten (12) tjener til å forhindre direkte varme-vekslerkontakt mellom væsken som skal bli fordampet og kondenserbar væske generert av væskefordampningen.
