The invention discloses a photovoltaic photo-thermal module combined with a micro-channel heat collector. The photovoltaic photo-thermal module comprises a photovoltaic power generation module, a fin micro-channel heat transfer module, a thermal insulation layer and an overall frame, wherein the fin micro-channel heat transfer module is clamped between the thermal insulation layer and the photovoltaic power generation module; the space between the fin micro-channel heat transfer module and the photovoltaic power generation module is filled with heat conducting silicone grease; and the photovoltaic power generation module, the fin micro-channel heat transfer module and the thermal insulation layer are packaged into a whole body in the overall module through the a groove buckling edge on the top of the overall frame and an iron sheet layer at the bottom of the overall frame. Due to the fins on the two sides of the fin micro-channel heat transfer module, the heat absorbing area is enlarged, the space is fully utilized, and the material is saved; due to the micro-channel structure of the fin micro-channel heat transfer module, the convective heat transfer coefficient and heat exchanging capability between single-phase flow and two-phase flow coolant fluid and the wall surface of a micro-channel can be greatly improved; and in addition, the photovoltaic photo-thermal module is simple in structure, convenient to manufacture and assemble, quite high in practical value, and capable of greatly improving the solar energy utilization ratio and quality.
