Abstract

<B>DISSIPADOR DE CALOR COMPOSTO<D>. A presente invenção é um dissipador de calor com um meio de transferência de calor para aumentar a capacidade de transferência de calor do dissipador de calor. Em uma modalidade, o dissipador de calor compreende várias aletas com cavidades, uma base e um meio fluido de transferência de calor. As aletas estão em contato térmico com a base e são configuradas para formar vários canais longitudinais através dos quais pode passar ar ou um meio fluido. O meio fluido de transferência de calor está contido em cada uma das cavidades. O meio fluido de transferência de calor aumenta a capacidade do dissipador de calor de transferir calor sem aumentar as suas áreas superficial dimensões e/ou peso. Este aumento é devido ao calor de vaporização e condensação latente do meio fluido de transferência de calor. Especificamente, é necessária um grande quantidade de energia para vaporizar o meio fluido de transferência de calor. Portanto, uma grande quantidade de calor pode ser conduzida desde a base para o meio fluido de transferência de calor. Reciprocamente, à medida que o meio fluido vaporizado de transferência de calor se condensa sobre as paredes superiores de esfriamento das aletas, uma grande quantidade de energia é conduzida do meio fluido vaporizado de transferência de calor para as aletas. Portanto uma grande quantidade de calor pode ser conduzida do meio fluido de transferência de calor para as aletas as quais podem ser seguida dissipar o calor para ambientes circundantes a menores temperaturas.
