Embodiment

[0031] Such as image 3 As shown, this is an embodiment of the present invention, wherein the number 11 is a silicon solar cell power generation panel, which is connected with 11 and is a solar heat generating box 12 below it. When the sun shines, the electric energy is output from the connecting wire 15, and at the same time, the working fluid carrying heat energy flows out from the heat generating outlet 14. The screw control device 13 plays the role of balancing the flow of working fluid.

[0032] The solar electric heat cogeneration device of the present invention can generate electricity and heat, and achieves double benefits in one fell swoop. In this way, the utilization rate of solar energy can be greatly improved, and the cost of solar energy utilization can be reduced. It has certain positive significance for energy saving, environmental protection and energy substitution.

Abstract

The disclosed equipment consists of integrated day lighting generating board and heat production box. The generating board is composed of sunlight transparent sheets and solar cell pieces. Heat sink layer, heat conducting layer and heat transferring working medium are setup under solar call pieces. Structure of heat production box includes following parts: heat transferring working medium through current limiting valve enters into the box, balanced allocator of guiding flow splits flows; heat transferring flow deflectors are as channel walls; heat energy from sun collected and transferred by heat sink layer, heat conducting layer are conducted to working medium; thus, temp of solar cell pieces are unchanged basically in order to raise electric-power output of solar cell pieces.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a solar power generation and heat generation device. Background technique [0002] Solar photovoltaics and solar collectors each have a range of products. But products that use solar radiation to generate electricity and provide heat at the same time have yet to come out. Related monographs and papers have not been publicly reported. According to the data search conducted by the applicant, only one article was found, "Preliminary Exploration of Solar Photoelectric Thermal Combined Application under Concentrating Conditions", Yang Zhiyong, Wang Yiping, "21st Century Solar Energy Technology", pages 490-492, Shanghai Jiao Tong University Press, 2003.9. It has no comparability with the conception, principle and method of the device of the present invention. [0003] The solar photovoltaic power generation device (or solar cell) will generate electricit...
