    Abstract: A photoenergy heat collector including an outer sleeve and multiple condenser lenses. The outer sleeve has a wall formed with multiple perforations passing through the wall of the outer sleeve from inner side to outer side. The condenser lenses are respectively inlaid in the perforations to focus light beams into the outer sleeve. A water flow can go into one end of the outer sleeve and flow through the outer sleeve and then flow out from the other end of the outer sleeve. Accordingly, as a heat exchanger, the heat of the light beams focused by the condenser lenses into the outer sleeve is absorbed by the water to heat the water. The photoenergy heat collector further includes an inner sleeve disposed in the outer sleeve and extending through the outer sleeve to serve as a passage for the water flow.
