Abstract

Um evaporador de refrigerante (1) constituído por laminar-se uma pluralidade de elementos tubulares (4) e um elemento tubular plano (50). Uma segunda passagem de refrigerante (53) no elemento tubular plano (50) é disposta em uma posição que é mais próxima e um tubo de saída de refrigerante (16). Na segunda passagem de refrigerante (53), algumas nervuras (34) são formadas de tal forma que as nervuras (54) elevem-se de uma placa plana (510 conectada a uma placa de metal (4a) para construir o elemento tubular plano (50). A segunda passagem de refrigerante (53) é dividida em diversas pequenas passagens de refrigerante. Por isso a área de fluxo de refrigerante da segunda passagem de refrigerante (53) é menor que a da outra passagem de refrigerante (31). Ou seja, a resistência ao fluxo de refrigerante da segunda passagem de refrigerante (53) é maior que a da outra passagem de refrigerante (31). Dessa forma o refrigerante é impedido de fluir para a segunda passagem de refrigerante (53) do elemento tubular plano (50).
