Photovoltaic photo-thermal assembly and heat collector

The heat collector comprises a built-in space and a wave-shaped flow channel plate arranged in the built-in space, the built-in space comprises two layers of heat absorption plates which are arranged up and down, and long edge sealing plates, gas end sealing plates and electric end sealing plates which are sealed on the four sides of the heat absorption plates; a plurality of inner cavity flow channels are formed between the flow channel plate and the heat absorption plate, and an inlet and an outlet communicated with the inner cavity flow channels are formed in the air end sealing plate. Streaming holes are formed in the runner plate and located in the two ends of the inner cavity runners, and the adjacent inner cavity runners are communicated through the streaming holes; the heat absorbing plates are flat metal plates; the attaching area of the heat absorbing plate and the photovoltaic panel is large, heat conduction is facilitated, the flatness is high, the deformation of the whole heat collector is greatl
