Abstract

a presente invenção refere-se a um trocador de calor com tubos de forma multilobada ou de "amendoim" substituindo os tubos redondos ou elípticos convencionais. os tubos têm uma seção transversal horizontal estreita e seção transversal vertical alta para permitir a multiplicação da área de superfície no mesmo volume de bobina, enquanto mantendo ou aumentando a área de passagem ao ar livre. esta configuração permite que a bobina tenha um coeficiente de transferência de calor externo total muito maior do que uma bobina convencional, enquanto a forma do tubo permite o uso de material mais fino, reduzindo o peso e o custo do trocador de calor.
