Abstract

"EVAPORADOR PARA SISTEMAS DE REFRIGERAçãO". Compreendendo um feixe de tubos (20) dispostos em série, afastados e paralelos entre si, carregando um fluido refrigerante e sendo incorporados e transpassados a uma pluralidade de aletas (10) dispostas em múltiplas fileiras estendidas transversalmente à direção de um fluxo de ar forçado (F) feito passar pelo evaporador (E) e por um ambiente a ser refrigerado, cada fileira sendo formada por uma pluralidade de aletas (10) dispostas de modo substancialmente paralelo à direção do fluxo de ar forçado (F) e incorporadas a pelo menos um dos referidos tubos (20). De acordo com a invenção, as aletas (10) incorporadas ao primeiro e ao segundo tubo, (20), segundo o sentido do fluxo de ar forçado (F), são espaçadas entre si por uma maior distância (d), quando operativamente associadas a um ambiente de resfriamento e por uma menor, distância (d) quando operativamente associadas a um ambiente de congelamento. As referidas distâncias (d) decrescem para cada dois tubos (20) subseq³entes até pelo menos o terceiro tubo (20), de modo a ser mantida em um valor mínimo para os demais tubos (20) subseq³entes.
