Glass vacuum solar energy collector tube - has horseshoe shaped tube reflector with internal black body

摘要

The solar energy collecting mirror deflects energy on black surface. The glass arrangement is designed to prevent build up of thermal stresses. A horseshoe shaped absorption tube coil has sharp curve opposite the mirror. This pointed curve forms the tip of the open end in the horsehoe profile. The expansion of the tube due to the internal pressure is compensated by straps. The connectors of the absorber coil are passed through flexible closing pieces. This absorption coil is held by spacing spiders or by wire holders.
