Title: Sistema de captação térmica de energia solar
Inventor: GODINHO LUIS HENRIQUE DE ANDREA LENCASTRE
IPC: F24S10/50
Filed: 2005-11-02
Abstract: O presente invento diz respeito a um sistema de captação térmica de energia solar para aquecimento de água que pode ser utilizado exposto directamente ao tempo, sistema vulgarmente utilizado para aquecimento da água de piscinas onde a temperatura de saída da água não pode ser muito alta ou, para temperaturas mais elevadas, encapsulado numa caixa isolada com o topo transparente de modo a formar um painel solar. A solução construtiva apresentada para os painéis permite que as dilatações diferenciais entre as suas zonas mais quentes e mais frias, agravadas pela possibilidade de utilização na sua construção de materiais com elevados coeficientes de dilatação e baixa rigidez, tais como os plásticos, não sejam restringidas, evitando-se assim deformações inaceitáveis nos seus componentes. Esta solução construtiva tem ainda a vantagem de permitir montar muito fácil e economicamente sistemas e painéis de diferentes dimensões a partir de elementos normalizados de baixo custo, adaptando-os e permitindo optimizar as áreas que estão disponíveis para a sua instalação.
