Abstract

trocador de calor de liga de alumínio, e, método para produzir um tubo de ref'rigerante é revelado um trocador de calor feito de uma liga de alumínio, '--- , que tem alta resistência a corrosão, que permite redução de peso de uma camada e do custo e, que é particularmente adequado como um trocador de calor automotivo. é especificamente revelado um trocador de calor feito de uma liga de alumínio, que é produzido pela aplicação de um agente de revestimento compreendendo uma mistura de um pó de si e um pó de fluxo de composto contendo zn e um ligante na supcrficie de um tubo de passagem de refrigerante, anexação de uma aleta nua feita de uma liga de al-mn-zn, e aquecimento o produto resultante em um forno de atmosfera para brasar a aleta nua. o trocador de calor é caracterizado pelo seguinte: o tubo de passagem de refrigerante compreende um material de extrusão feito de uma liga de alumínio compreendendo 0,5 a 1, 7 % de lv1n, menos que o, 1 o % de cu e menos que o, 1 o % de si, com o restante sendo ai e impurezas inevitáveis; na mistura, a razão de mistura do pó de si para o pó de fluxo do composto contendo zn é 10:90 a 40:60; o ligante é adicionado na mistura em uma quantidade de 5 a 40 % em relação à quantidade total do agente de revestimento; o agente de revestimento é aplicado na superfície externa do tubo de passagem de refrigerante em uma quantidade tal que o pó de si e o pó de fluxo do composto contendo zr sejam aplicados em uma quantidade total de 5 a 30 g/1112; a superfície do tubo de passagem de refrigerante apresenta um potencial elétrico menor que em uma área mais profunda do que a profundidade de difusão de si e zn depois da brasagem pelo aquecimento, e a diferença no potencial elétrico é 20 a 200 rn v; e a aleta tem um potencial elétrico menor que em uma área profunda do tubo de passagem de refrigerante.
