SUPPORTING STRUCTURE FOR PHOTOVOLTAIC PANEL

摘要

The invention relates to a field of photovoltaic panels, and specifically to photovoltaic panels operating with irrigation of their backsides by liquid heat transfer medium.;More specifically, the invention proposes a supporting structure for active cooling a photovoltaic solar panel fastened on a supporting metal plate, which is irrigated on its backside with relatively low flow rate of heat transfer medium, which flows in the form of some rivulets. The invention describes some technical solutions, which restrict meandering rivulets flow on this backside.;The proposed supporting structure in combination with an installed photovoltaic panel can be used at nighttime for cooling water or another heat transfer medium. This cooled water can be applied for air conditioning of a dwelling or for cooling the photovoltaic panels at daylight time.

1. A supporting structure for active cooling a photovoltaic solar panel, said supporting structure consists of:
a supporting structural frame, which comprises in turn a top rectangular frame and a bottom rectangular frame joined by some connectors; said top rectangular frame serves for installation of a supporting metal plate, which serves for mounting said photovoltaic solar panel with its back sheet on said supporting metal plate by adhesive; said supporting structural frame is positioned in its operating state in such a way, that said top rectangular frame is tilted with respect to the horizontal plane; a receiving chute, which is joined with the lower section of the backside of said supporting metal plate; said receiving chute is provided with an outlet connection serving for removal of cooling liquid medium; a distributing pipe; the proximal section of said distributing pipe is placed outside said supporting metal plate, and its middle and distal sections are installed on the backside of said supporting metal plate; the middle and distal sections of said distributing pipe are provided with openings, which supply evenly water or another cooling liquid medium on the upper section of the backside of said supporting metal plate; the upper section of the backside of said supporting metal plate is provided with some pipe clips serving for fastening said distributing pipe; longitudinal members for restricting rivulets' flow meandering; said longitudinal member divide the backside of said supporting metal plate into a set of parallel zones; said longitudinal members entrap the rivulets when they meet said longitudinal members with following transformation of the shapes of said rivulets and their flowing in their transformed shapes along said longitudinal members.
