Abstract

"TROCADOR DE CALOR PARA PROPICIAR REFRIGERAçãO SUPERCRìTICA DE UM FLUIDO DE TRABALHO EM UM CICLO DE REFRIGERAçãO TRANSCRìTICO". Trocador de calor (10) para propiciar refrigeração supercrítica para o refrigerante de um sistema de refrigeração transcrítico (12) que inclui um par de tubos de comunicação alongados (20, 22), uma pluralidade de tubos alongados (28) espaçados em relação lateral ao longo dos eixos geométricos longitudinais (24, 26) dos tubos de comunicação (20, 22), e aletas de serpentina (30) que se estendem entre pares adjacentes dos tubos. Cada um dos tubos (28) está dobrado sobre si mesmo para definir pelo menos duas pernas paralelas (36) dos tubos (28) e tem uma seção transversal achatada. As pernas paralelas (36) dos tubos (28) estão de preferência afastadas uma da outra, com a dimensão maior D de cada uma das pernas paralelas ficando em um plano comum. Cada uma das aletas (30) inclui abas (40) e separações alongadas (42) alternadas que se estendem paralelas às pernas paralelas (36) e localizadas entre as pernas paralelas (36) dos tubos adjacentes (28) para dividir a largura (W) de cada aleta (30) em elementos de aletas discretos (44) que estão ligados entre si pelas abas (40). Cada um dos elementos de aletas (44) estende-se ao longo das pernas paralelas (36) dos tubos adjacentes (28)."Heat Exchanger to Provide Supercritical Cooling of a Working Fluid in a Transcritical Cooling Cycle". Heat exchanger (10) for providing supercritical cooling for the refrigerant of a transcritical cooling system (12) including a pair of elongate communication tubes (20, 22), a plurality of elongate tubes (28) spaced lateral to the along the longitudinal geometric axes (24, 26) of the communication tubes (20, 22), and coil fins (30) extending between adjacent pairs of tubes. Each of the tubes (28) is bent over itself to define at least two parallel legs (36) of the tubes (28) and has a flat cross section. The parallel legs 36 of the tubes 28 are preferably spaced apart with the largest dimension D of each of the parallel legs being in a common plane. Each of the fins (30) includes tabs (40) and alternate elongated separations (42) extending parallel to the parallel legs (36) and located between the parallel legs (36) of adjacent pipes (28) to divide the width (W ) of each fin (30) into discrete fin elements (44) which are connected to each other by the tabs (40). Each of the fin members (44) extends along the parallel legs (36) of the adjacent tubes (28).
