Abstract

"TURBILHONADOR PARA TROCADOR DE CALOR". é apresentado um trocador de calor (10) do tipo que tem pares de chapas ou tubos empilhados (12) que definem passagens de fluxo, com o turbilhonador (18, 30, 45, 50, 55, 60) localizado no interior de tais passagens de fluxo. Os turbilhonadores (18, 30, 45, 50, 60) são do tipo de metal dilatado que tem fileiras de convoluções (32, 34). As convoluções (32, 34) são interrompidas periodicamente, de modo a se formarem zonas de recuperação de pressão não convoluídas (40) localizadas entre ou a jusante das convoluções (32, 34). Além disto, as fileiras (32, 34) podem ser afastadas entre si de modo a se obterem zonas neutras longitudinais (56, 61) entre as fileiras de convoluções. As zonas de recuperação de pressão (40, 56, 61) e canais neutros longitudinais (62) reduzem a queda de pressão no trocador de calor (10) sem reduzir apreciavelmente a transferência térmica."TURBILHONADOR FOR HEAT EXCHANGER". a heat exchanger (10) of the type that has pairs of stacked plates or tubes (12) that define flow passages is presented, with the whirlwind (18, 30, 45, 50, 55, 60) located inside such passages flow. The whirlpools (18, 30, 45, 50, 60) are of the type of swollen metal that has rows of convolutions (32, 34). Convolutions (32, 34) are interrupted periodically, in order to form non-convoluted pressure recovery zones (40) located between or downstream of the convolutions (32, 34). In addition, the rows (32, 34) can be spaced apart in order to obtain longitudinal neutral zones (56, 61) between the rows of convolutions. The pressure recovery zones (40, 56, 61) and neutral longitudinal channels (62) reduce the pressure drop in the heat exchanger (10) without appreciably reducing thermal transfer.
