PARABOLIC COLLECTOR SOLAR RADIATION ABSORBER TUBE (RECEIVER ELEMENT)

摘要

A parabolic collector solar radiation absorber tube (receiver element) designed with this applied shape for enhancing reducing the thermal losses emissivity and the rays reflectivity specifications. The HTF (heat transfer fluid) going through an heat receiver consists of steel tube (2) inserted in aluminum heat sink tube (3) have diameter bigger. The tube surface, surrounded by an air evacuated glass tube (6). The HCE incorporates glass-to-metal seals and metal bellows to achieve the vacuum-tight enclosure. The vacuum enclosure serves primarily to protect the aluminum heat sink surface and to reduce heat losses at the high operating temperatures when contact with the outer air.
