Benefits of technology

[0006]On this background, it is an object of the present invention to provide a solar collector in which the absorber is secured in a reliable and flexible manner. This object is achieved in accordance with claim 1 by providing solar collector comprising a frame, preferably made of extruded or rollformed metal, an absorber plate, absorber tubing secured to the rear side of the absorber plate, an insulating layer beneath the absorber plate, a cover pane spaced above the absorber, four or more mounting brackets for connecting the absorber with the frame, said mounting brackets engage the absorber tubing, whereby a first mounting bracket engages the absorber tubing in a manner that does not allow any substantial displacement between the first bracket and said absorber tubing, a second mounting bracket engages the absorber tubing in a manner that allows d

Problems solved by technology

The other mounting brackets allow a substantially unhindered thermal expansion of the absorber plate, and this there amount of tension an stress that

Embodiment Construction

[0030]A preferred embodiment of the invention will be described specifically with reference to a flat plate collector assembly although it is understood that other absorber types may be employed with a minimum change in construction.

[0031]FIG. 1 shows by way of illustrative example a flat plate solar energy collector. Seen in cutaway perspective view of FIG. 1 the solar collector has a frame 1, an insulation layer 2, an absorber plate 3 and a cover pane 4. The frame, the insulation layer and the cover pane form a case with an enclosure. The enclosure is used to provide support for the absorber, and to protect the collector from heat loss due to wind, plus the important function of keeping moisture from rain, snow and dew out of the collector.

[0032]The insulation layer 2 is made of a rigid foam urethane (PUR) or polyisocyanurate (PIR). These materials have an excellent insulation value per unit of thickness and are easy to handle because they are very light. They have also a higher c...

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...
