Abstract
Patente de Invenção: <B>"ELEMENTOS DE TRANSFERêNCIA DE CALOR PARA PREAQUECEDORES DE AR E MéTODO PARA SUA FABRICAçãO"<D>. Elementos de transmissão de calor (34) para intercambiadores de calor regeneradores e rotativos são fabricados com nervuras ou ranhuras espaçadas (42) possuindo indentações de perturbação do fluxo (46) nos picos das nervuras (42) formadas a intervalos selecionados para se projetarem nos canais de fluxo (36, 38). Estas projeções (46) interrompem a camada limite e causam turbulência e mistura para aumentar a transferência de calor. Vários métodos de formação das indentações (46) são descritos.
