Problems solved by technology

CN101806514A Chinese patent document also discloses a building composite solar photovoltaic hot water cooling and heating system, which utilizes solar power to achieve indoor cooling and heating in summer and winter respectively, and its separate heat pipe, integral gravity heat pipe The hot water system consisting of heat exchange headers, coils, water tanks, etc. is complex, and the system also fails to solve the problem that the system cannot effectively heat in weak solar radiation and rainy days
It can be seen that, including the above-mentioned patent documents, most of the current solar water heaters are difficult to solve the heating problem when the solar radiation is weak and it is rainy, so that users can only use electric heating to produce hot water, and most systems have The structure is complex, the preparation cost is high, the photoelectric and photothermal systems are independent, and the effective conversion and unification of light, heat and electricity cannot be realized.

Abstract

The invention discloses a solar photovoltaic thermoelectric heating module, which comprises a glass cover plate, a packaging photovoltaic cell plate, a cold-end radiator, a semiconductor thermoelectric chip group and a hot-end flat-plate heat pipe radiator from outside to inside in turn, wherein a pipe radiator is adhered to a condensing end of the hot-end flat-plate heat pipe radiator; and heat-insulated materials are arranged in a gap between the two radiators and on the bottom side of the hot-end flat-plate heat pipe radiator. A photovoltaic thermoelectric hot water system comprises a photovoltaic thermoelectric heating module group, a thermoelectric air source heating module group, a heat storage water tank and a photovoltaic power supply module, wherein the two module groups are connected with the heat storage water tank; each module group comprises a plurality of modules which are connected in series / in parallel with one another and communicated with the heat storage water tank;a photoelectric controller in the photovoltaic power supply module is connected to the packaging photovoltaic cell plate; and an electrical storage device is connected to the semiconductor thermoelectric chip group of each module group. According to the system, the chip temperature is reduced, the power generation efficiency is improved, and comprehensive solar photoelectric and photo-thermal utilization can be realized at low cost and high efficiency.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and relates to a comprehensive utilization technology of solar photoelectricity, light and heat, in particular to a solar photovoltaic thermoelectric heating module and a photovoltaic thermoelectric hot water system. Background technique [0002] With the increasing shortage of conventional energy and the increasing environmental pollution, solar energy, as a clean and renewable energy, has been paid more and more attention by people. The photoelectric conversion efficiency of general commercial solar cells is only 6% to 15%. Improving system efficiency and reducing overall cost have become the key to the application of solar photovoltaic building integration. Traditionally, improving the efficiency of solar photovoltaic power generation often only focuses on the improvement of silicon crystal or amorphous materials. In fact, the power generation efficiency of silicon cells depends heavil...
