Abstract

<B>DISPOSITIVO PARA ALOJAR EQUIPAMENTOS DE COMUNICAçãO E ELETRôNICA UTILIZANDO MATERIAL DE COEFICIENTE DE TEMPERATURA POSITIVA<D>. Invólucro aperfeiçoado para alojar equipamentos de eletrônica e comunicação compreende um elemento de aquecimento fabricado com um material de coeficiente de temperatura positiva. O invólucro é particularmente útil para alojar equipamentos de comunicação e estações de base de local de célula para sistemas de telefonia celular ao ar livre; tem capacidades de aquecimento de auto-regulagem que não dependem de parâmetros de voltagem, permitindo, desse modo, seu uso em locais geográficos distintos. Em uma modalidade preferida, uma pluralidade de elementos de aquecimento PTC são utilizados e seletivamente localizados adjacentes a uma pluralidade de regiões de conjunto de circuitos. Energia CC pode der utilizada para energizar os aquecedores PTC, e o invólucro pode ser utilizado para equipamento de telefonia operando com energia CA ou CC.
