Abstract

A solar collector with a rectangular frame (1), preferably made of extruded or rollformed metal, containing an absorber plate (3), an insulating layer (2) beneath the absorber plate (3), and a cover pane (4) spaced above the absorber (3). Absorber tubing (3b.3c) is attached to the rear side of the absorber plate. The absorber (3) is secured to the frame (1) by mounting brackets (11a,11b) that engage the absorber tubing (3b,3c) and allow for substantially unhindered thermal expansion and contraction of the absorber. The collector can be integrated or roof mounted on a pitched roof, or may be installed on a flat roof by means of a mounting frame.

Description

[0001] The present invention relates to solar collectors and mounting brackets, in particular solar collectors that include a rectangular frame, preferably made of extruded or rollformed metal, containing an absorber plate, an insulating layer beneath the absorber plate, and a cover pane spaced above the absorber. Absorber tubing is attached to the rear side of the absorber plate. The collectors can be integrated or roof mounted on a pitched roof, or may be installed on a flat roof by means of a mounting frame.BACKGROUND ART

[0002] WO 2004 / 111550 discloses such a type of solar collector. The absorber is simply inserted in the frame or another housing. The absorber is held in place by the connection of the absorber tubes to the frame, but it is also known to hold the absorber in place by imbedding the absorber in the insulation material.

[0003] Neither method for securing the absorber is ideal. A stiff connection between the absorber tubes and the frame cannot provide for the required fle...
