Referring to the accompanying drawings, a multifunctional heat pipe solar collector includes a frame 2 installed on the outer wall of the house. The front and rear sides of the frame 2 are respectively equipped with a glass cover 1 and a rear cover 11. The rear of the glass cover plate 1 is respectively equipped with a plurality of photovoltaic cell panels 7 connected in series and vertically arranged, and a heat collecting tube 14 arranged horizontally is installed in the frame 2, and a plurality of heat conducting plates 12 are respectively fixed in the heat collecting tube 14. Copper sleeves 13 are respectively connected between two adjacent heat conduction plates. Multiple heat conduction plates 12 and copper sleeves 13 divide the interior of the heat collecting tube 14 into a water flow channel and an air flow channel. The two ends of the water flow channel and the air flow channel are respectively A water inlet 3, an air inlet 4, a water outlet 5, and an air outlet 6 are provided; multiple heat pipes arranged vertically are arranged in the frame 2, and the evaporation sections 8 of the multiple heat pipes respectively extend to two adjacent photovoltaic In the gap between the battery plates, the condensation sections 9 of the plurality of heat pipes are respectively inserted into the copper sleeves 13 correspondingly.
