Abstract

Se describe una cubierta para circuitos electricos, la cual suministra blindajes a los circuitos protegiendolos de los fenomenos de EMI. E l circuito tiene un medio para establecer contacto termico con los componentes generadores de calor dentro de la cubierta, lo que permite utilizar la cubierta como un disipador termico para disipar el calor. La cubierta comprende un armazon, una cubierta y un elemento que se proyecta hacia adentro para hacer contacto termicamente con la fuente de calor dentro de la cubierta. El elemento que se proyecta hacia adentro se disena de manera que no provoca abertura alguna en la cubierta. El elemento que se proyecta hacia adentro puede ser una parte integral del armazon o la cubierta y todas las partes de la cubierta se pueden producir ventajosamente utilizando procedimientos de corte y doblado.
