NOVELTY - The utility model claims a double-slope roof photovoltaic assembly radiating device, wherein It comprises a photovoltaic component, a fin, a radiating aluminium pipe, a heat collecting aluminium pipe and a chimney; the upper surface of the radiating aluminium pipe is connected with the back plate of the photovoltaic assembly; multiple ribs are uniformly arranged on the inner wall of the upper surface of the radiating aluminium pipe; the included angle between the heat collecting aluminium pipe and the radiating aluminium pipe is equal to the included angle between two slope surfaces of the double-slope roof; the chimney is connected with the heat collecting aluminium pipe. The utility model is based on solar chimney effect strengthening convection heat exchange principle, at the same time using rib, graphene further strengthening radiating, capable of effectively using the roof space, strengthening the photovoltaic assembly radiating, improving the generating efficiency.
