Solar collector

摘要

A solar collector comprises an evacuated glass tube (8), an absorbing section (9) comprising a radiation absorbing plate (10), an elongate tube (11, 15) for a working fluid in contact with the radiation absorbing plate (10) and a wire clip (25) for retaining the absorbing section (9) in position in the solar absorbing glass tube (8). The wire clip (25) consists of a single piece wire having a clamping portion (26) for clamping onto the outer surface of the working fluid tube (11, 15) and a pair of resilient side support sections (27) flanking the clamping portion (26). The side support sections (27) extend so that portions thereof engage against the inner surface of the solar absorbing tube (8).

1. A solar collector comprising
an evacuated radiation transparent solar absorbing tube, an absorbing section comprising a radiation absorbing plate, an elongate tube for a working fluid in contact with the radiation absorbing plate, and a retaining means for retaining the absorbing plate in position in the solar absorbing tube, wherein the retaining means retains the absorbing section in a central position within the evacuated radiation transparent solar absorbing tube and wherein the retaining means comprises: a single piece wire clip having a clamping portion extending partially around and clamping onto an outer surface of the working fluid tube and, a pair of resilient side support sections flanking the clamping portion and connected to the clamping portion by arcuate connecting sections, the side support sections extending so that portions thereof engage against an inner surface of the solar absorbing tube and wherein the side support sections and arcuate connecting sections extend through openings in the surface of the radiation absorbing plate.
