AN IMPROVED HEAT COLLECTION ELEMENT FOR LINEAR COLLECTOR

摘要

The present invention provides improved Heat Collection Element (1) for Linear Solar Collector for temperature range 50°C-350°C. It comprises of Helical Coil (4) with spaced pitch of its helical turns on ends providing Expansion Compensating Mechanism (5); Glass Cover (6) to avoid thermal losses; Space between said Helical Coil (4) and said Glass Cover (6) filled with heat conductive gases; End Covers (2a and 3a) to close said Glass Cover (6); End Seals (2d and 3d) to avoid leakage of gases; Connection Hose (2h and 3h) for ingress and egress of Heat Transfer Fluid; secondary reflector (8) for reflecting back the rays that bypasses Helical Coil (4); Clipping Arrangement (9) for fixing said Secondary Reflector (8) on said Glass cover (6); Joining Piece (12) to facilitate interconnection of two units of said Heat Collection Element (1) when arranged in plurality in series; and mounting arrangement (13) to mount said series at site.
