High efficiency flat plate solar collector

Flat-plate collectors are the most common solar collectors for use in solar water-heating systems in homes and in solar space heating. A flat-plate collector consists basically of an insulated metal box with a glass or plastic cover (the glazing) and a dark-colored absorber plate. Solar radiation is absorbed by the absorber plate and transferred to a fluid that circulates through the collector in tubes.

1. Features compare to vacuum tube collector(1) More energy output from a unit area, less roof occupied;(2) Plate-grid structure, fluid heated in the copper pipe with faster heat transfer; (3) Working with pressure, better stagnation performance;(4) Graceful outline, well matched to the building;(5) Stable quality, free maintenance and long life span.

2. Advantages of DAILY flat plate solar collector(1)Blue titanium coating, with high absorptivity 95±2% and low emissivity 4±2%, stable performance, life span 50years;(2)Special design structure, 360°heat transfer, excellent thermal conductivity;(3)Optical low iron tempered glass cover, light transmit up to 92%, reflection and refraction make the “greenhouse effect” shaped in the cavity, reduce heat loss;(4)Integrated frame design, nice outlook, stable structure, easy to install;(5)Integrated polyurethane foaming, thicken back and side insulation, less heat loss;(6)12 riser tubes design, better than the normal 7/ 8 tubes, absorber plate surface thermal migration greatly reduced;
