Abstract

aparelho permutador de calor evaporativo com conjunto de serpentina tubular elíptica aletada. expõe-se um conjunto de tubos de serpentina com aletas aperfeiçoado (24, 24a, 24b, 24d) que aumenta o desempenho do permutador de calor evaporativo (26, 26a, 26b, 26c, 26d), e inclui tubos (10), de preferência tubos de serpentina, no conjunto de serpentina. os tubos são dotados de uma seção transversal de uma maneira geral elíptica com aletas externas (20) formadas em uma supefície externa dos tubos. as letas são espaçadas substancialmente de 1,5 até substancialmente 3,5 aletas por polegada (2,54cm) ao longo do eixo longitudinal (13) dos tubos, estendem-se substancialmente de 23,8% até substancialmente 36% do diâmetro nominal externo do tubo na altura a partir da superfície externa dos tubos e têm uma espessura de substancialmente 0,018 cm (0,007 de polegada). os tubos são dotados de um espaçamento de centro a centro (dh) de uma maneira geral horizontal e normal ao eixo longitudinal dos tubod de substancialmente 109% até substancialmente 125% do diâmetro nominal externo do tubo, e um espaçamento de centro a centro (dv) de uma maneira geral vertical de substancialmente 100% até cerca de 131% do diâmetro nominal externo do tubo.
