The heat engine 2 is located in the solar heat collecting chamber 11, specifically, the heat engine 2 is, for example, a stirling engine, an expansion chamber of the stirling engine is extended into the solar heat collecting chamber 11, a heat absorbing component, such as a heat conducting pipe 3, is coated on the heat engine 2, and an electricity generating unit 20 is connected to the heat engine 2, and the electricity generating unit 20 is, for example, connected to a piston rod of the stirling engine. The double-heat-source solar heat collector also comprises a heat insulation layer 4 which is coated on the outer wall of the heat source chamber 12, for example, a hollow layer of a hollow container is filled with a asbestos layer, and the body 1 is placed in the hollow container; a lens 5 made of quartz glass is arranged on the body 1, so that the lens 5 corresponds to the solar heat collecting chamber 11, and specifically, a cover member 6 is covered on the body 1, the center of the cover member 6 is hollow, and the lens 5 is supported on the cover member 6. The double-heat-source solar heat collector further comprises a heat generating unit 7A, in this embodiment, the heat generating unit 7A is disposed outside the heat source chamber 12, and the heat generating unit 7A is communicated with the heat source chamber 12 through a first conveying pipe 71A.

Referring to fig. 2 and 3, when sunlight is sufficient in the daytime, sunlight passes through the lens 5 with heat-collecting effect to focus solar heat on the heat engine 2, so that the heat engine 2 absorbs enough solar heat to drive the power generation unit 20 to generate power, thereby converting the solar heat into electric energy. Wherein, the surface area of the heat absorption of the heat engine 2 can be increased by receiving the solar heat energy through the heat conduction pipe 3, so as to further improve the heat efficiency.
