Abstract

''MONTAGEM DE PLACA DE CIRCUITOS EMPILHADA ADAPTADA PARA DISSIPAçãO DE CALOR'' Um aparelho é fornecido para dissipação de calor de uma montagem de placa de circuitos empilhada. O aparelho inclui placas de circuito que são orientadas em planos espaçados que se estendem substancialmente paralelos um ao outro. Um dispositivo de transferência de calor conectado nas placas de circuito transfere calor entre as placas de circuito. Um dispositivo de dissipação de calor conectado em pelo menos uma das placas de circuito dissipa pelo menos uma porção do calor transferido.
