Abstract

L'invention concerne un collecteur solaire comprenant un boîtier et une zone d'absorption efficace à l'intérieur du boîtier. Le boîtier présente la forme d'une boîte fermée et inclut un élément récepteur ainsi qu'un couvercle au moins partiellement transparent. L'énergie solaire pénètre dans le boîtier à travers le couvercle pour chauffer un fluide à l'intérieur de la zone d'absorption efficace, et la zone d'absorption efficace comprend un distributeur d'entrée, un distributeur de sortie espacé de celui-ci et une pluralité de tubes en plastique qui s'étendent entre les distributeurs. L'un des distributeurs est fixé de manière rigide au boîtier et l'autre distributeur est fixé de manière flexible au boîtier par le biais d'au moins un joint flexible.
