Embodiment Construction

[0088] Such as Figure 2 to Figure 44 As shown in , the direct current solar collector assembly includes a solar absorbing tube 3, which includes an evacuated transparent radiation cover 8 enclosing an absorbing portion 9, which includes a radiation absorbing panel 10 for absorbing solar radiation and contains working An elongated tube 11 of fluid (heat transfer medium) is in thermal contact with said radiation absorbing plate 10 . The elongated tube 11 comprises a concentrically arranged inner tube 12 forming two concentric inner flow channels 13, 14 for the fluid to be heated. An elongated tube 11 protrudes from one end of the solar absorbing tube 3 and enters an end fitting 15, wherein the annular outer channel 13 of the elongated tube 11 communicates with a cold fluid inlet pipe liquid flow 16 in the end fitting 15, and the elongated tube 11 Internal channel 14 communicates with hot fluid outlet tube flow 17 within end fitting 15 . Fluid travels from the annular outer ch...

Abstract

A solar collector of the direct flow type comprises a solar absorbing tube 3 containing elongate tube 11, and a working fluid. The elongate tube 11 contains a concentrically positioned inner pipe 12 thereby forming two concentric internal flow passage ways 13, 14 for the flow of a fluid to be heated. The elongate tube 11 extends out of one end of the solar absorbing tube 3 and into an end fitting 15 wherein an annular outer passageway 13 of the elongate tube 11 communicates with a cold fluid inlet conduit 16 within the end fitting 15 and the inner passageway 14 of the elongate tube 11 communicates with a hot water outlet conduit 17 within the end fitting 15. A central dividing wall 19 divides the fitting 18 into the cold fluid inlet conduit 16 and the hot fluid outlet conduit 17. The dividing wall 19 is a separate insert component which is mounted in the passageway. Fluid can flow between the tubular passages 18 of adjacent solar tubes 3. The open ends of the passages 18 comprise recesses to provide a circumferential seat 20 for an o-ring 21 or similar sealing means to provide a fluid-tight seal when adjacent end fittings 15 are mounted together.

Description

technical field [0001] The present invention relates to a solar collector for converting solar radiation into heat and transferring the heat with the highest possible efficiency to a fluid heat transfer device (such as water or air), whereby the heat can be used for domestic or industrial applications , for example for heating domestic hot water or central heating systems. Background technique [0002] Typically, a solar collector comprises a plurality of elongated tubes containing radiation absorbing panels for absorbing solar radiation, through which the fluid to be heated may pass or within which are used to transfer heat to the The tubes of the working fluid are in contact with the heated fluid. The radiation absorbing panels and at least a portion of the tubes are enclosed within an evacuated transparent radiation enclosure to prevent heat loss. [0003] In one type of solar collector known as the once-through type, the fluid to be heated flows through tubes in contac...
