The Heat Transfer Model of V Shaped Solar Flat-Plate Air Collector

The V-shaped solar flat-plate air collector was put forward according to the existing problems of solar flat-plate air collector. V-shaped grid plate is used in the solar flat-plate air collector which can improve the efficiency of a flat-plate solar air collector via increase of solar energy absorption efficiency and heat transfer area. Energy balance model of the V-shaped solar flat-plate air collector is established according to the characteristics of internal structure and air flow way, and vent opening position is optimized using the CFD, the results showed that the temperature distribution is uniform when air inlet locates in the central axis of collector, it will provide a theoretical basis for the design of the V-shaped solar flat-plate collector.
