Embodiment Construction

[0027] Below in conjunction with embodiment will further explain accompanying drawing and illustrate the invention of the present invention.

[0028] exist figure 1 Among them, the present invention transforms the solar water heater into a "solar oil heater", with the purpose of increasing the heating temperature of the solar water heater and increasing the output power of thermopile temperature difference power generation. Because the oil medium has a high boiling point and good heat storage, it is not easy to scale for long-term work, and the output oil temperature can be several tens of degrees higher than the water temperature. The drying temperature of solar water heaters can reach above 270°C, and it is entirely possible to heat the oil medium to 170-180°C, that is to say, it is simple and easy to transform solar water heaters into "solar oil heaters".

[0029] The oil heated by the solar oil heater (1) enters the heating liquid tank (8) through the hot liquid circulati...

Abstract

The invention provides a miniature solar generating unit which comprises solar heating equipment and a temperature difference power generating set, wherein the temperature difference power generating set comprises a thermoelectric pile array, a heat supply fluid container and a heat radiator, one surface (hot surface) of a thermoelectric pile is tightly attached to the heat supply fluid container (8), and the other surface (cold surface) of the thermoelectric pile is tightly attached to the heat radiator to form temperature difference for powe4r generation. The miniature solar generating unit changes an operating medium 'water' of a solar water heater into high-boiling point 'oil' so that heating temperature is improved to 150-160 DEG C, thus significantly increasing output power of the temperature difference power generating set. The miniature solar generating unit is suitable for household power supply or directly used for load of electrical equipment in need of DC supply or power supply matched with a DC inverter technology for power supply, and excessive electric energy can be fed to a power grid; and temperature of the delivered cooling water can reach 40-50 DEG C, thus being capable of being used for household heating, bathing and living. The low-cost and multifunctional solar generating unit is favorable for popularization to really realize energy conservation and emission reduction as well as environmental protection.

Description

technical field [0001] The invention relates to a power generation device using solar energy as a heat source, in particular to a solar miniature generating set that uses a modified solar water heater to supply heat, and uses a thermopile temperature difference to generate electricity to realize heat-electricity direct conversion. Background technique [0002] In order to save energy, reduce emissions and protect the environment, it is a good way to use solar power to generate electricity and heat. The current solar power generation method adopts the form of solar photovoltaic cell energy conversion to establish a solar photovoltaic power station. The cost of this solar photovoltaic power station is relatively high, which is not conducive to popularization and application. Solar water heaters use vacuum glass tube heat collection technology to heat water for daily needs. [0003] The Seebeck effect is the theoretical basis of thermoelectric power generation, and semiconduct...
