Abstract
The invention discloses a closed loop capillary flat plate type solar heat collector, which belongs to the field of solar heat collector. The solar heat collector is characterized in that the device comprises a header tube, a fin tube, capillary metal tubes, a graphite heat transfer layer, a metal frame, plate glass and an insulation layer; the inner diameter of each capillary metal tube is between 2 and 5 millimeters, and the capillary metal tubes are connected with the fin tube to form a closed pipe system. The capillary metal tubes are filled with a heat transfer medium; during work, after absorbing solar energy, the heat transfer medium forms a vapor and liquid alternated column, enters the fin tube along the capillary metal tubes, flows back to the capillary metal tubes after being cooled down and condensed by media outside the tube, and then absorbs solar energy again for vaporization; and the cycle is repeatedly carried out. The closed loop capillary flat plate type solar heat collector has the advantages that the oscillatory flow heat pipe effect caused by the closed loop capillary metal tubes increases the heat transfer rate of the heat collector; the graphite heat transfer layer facilitates the improvement of the heat collection performance of the heat collector; and the tube diameter of each capillary metal tube is small, thereby improving the bearing capacity of the heat collection tube.
