Solar collectors

摘要

A solar collector using a basic element suitable for modular construction is described, comprising an absorber panel including a plurality of metal extrusions attached together in the direction of the width of the panel, and further metal extrusions each cut along a diagonal line and attached to the opposite ends of the absorber panel to form the inlet and outlet manifolds. The solar collector further includes transparent window panels attached to the housing frame by a mounting having a resilient partition facing the absorber panel to partition the space between the transparent panel and the absorber panel and thereby to reduce convection losses.
