Abstract
êMBOLO DE METAL LEVE COM TUBOS DE CALOR. A presente invenção refere-se ao caso de um êmbolo de metal leve (10) com tubos de calor, com uma simplificação da construção do êmbolo que deverá ser obtida uma dissipação de calor melhorada das áreas do êmbolo submetidas ao calor, evitando-se, com isto, tensões térmicas pelo fato de que, em uma infinidade de tubos de calor, cheios de liquido, equipados com lado do evaporador (6a) e lado do condensador (6b), que no lado do evaporador os tubos de calor (6) são formados através de seções de tubo curtas que estão dispostas na espessura do fundo, orientadas na direção de irradiação da combustão, para o fundo do êmbolo e estão ligadas por meio de um tubo de calor composto (7) que passa paralelo ao fundo do êmbolo, sendo que, pelo menos, duas seções de tubo, que atuam como lados do condensador (6b), estão acopladas com o tubo de calor composto (7), de tal modo que, através de uma ligação de tubos (8) disposta em suas extremidades (7a) do lado do condensador, é realizado um circuito de processo fechado continuo do líquido de resfriamento entre o lado do evaporador, o tubo de calor composto e o lado do condensador dos tubos de calor (6).
