Abstract

"MONTAGEM EM ESPIRAL PARA UM TROCADOR DE CALOR, E, TROCADOR DE CALOR". Um projeto e um método de fabricação de montagem em espiral de trocador de calor aumenta a área de superfície de transferência de calor para um dado tamanho de trocador de calor aumentando a densidade de compactação de circuitos na dada serpentina. A montagem em espiral de trocador de calor preferivelmente aumenta a densidade de circuito uniformemente e precisamente. Isto permite que o número de circuitos na montagem em espiral de um trocador de calor seja aumentado do que teria sido considerado previamente possível para prover área de superfície de transferência de calor máxima para um dado tamanho de trocador de calor. A montagem em espiral é constituída de arranjos de circuitos de serpentina substancialmente igualmente espaçados separadamente localizados na região de montagem em espiral do conduto, com circuitos adjacentes sendo arranjados de um modo deslocado paralelo no qual curvas de retorno adjacentes são sobrepostas. Os tubos tem um diâmetro efetivo D. áreas de depressão são providas nos pontos de sobreposição para reduzir localmente o diâmetro na sobreposição. Isto provê um espaçamento de circuito para circuito com uma densidade D/S > 1,0, preferivelmente maior que 1,02, onde S é o espaçamento entre circuitos adjacentes e D é o diâmetro efetivo dos tubos. As áreas de depressão provêem só um aumento mínimo em queda de pressão de fluido interna, mas resultam em área de superfície de transferência de calor aumentada como circuitos adicionais podem ser adicionados em uma dada aplicação de limitação de tamanho. A queda de pressão aumentada é mais que compensada por uma diminuição resultante em queda de pressão de fluido interna devido ao aumento em área de fluxo interna. A montagem em espiral inventiva é útil com vários tipos de trocadores de calor.
