Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
In the utility model, shown in Fig. 2,3, solar panels 1 are made up of solar panel 11 and coldplate 12.Cell panel 11 produces electricity, and in coldplate 12, the heat that solar radiation produces is taken away by recirculated water, maintains cell panel and is in reasonable working temperature state.By being contained in the pipeline in coldplate in advance, solar panels are linked together, composition photovoltaic generation cooling unit, solar power system is made up of one or more cooling unit.Solar panels cooling circulating water, is provided by the first circulating pump.Water through the cooling of source, ground is delivered to every block solar panels by it.From the high-temperature water of solar panels, deliver to underground by the second circulating pump, after cooling, arrive the water inlet end of the first circulating pump.
The effect of the 3rd circulating pump is by the part or all of high-temperature water from solar panels, flows through in hot water storage tank and carries out heat exchange, return in supervisor.The hot water of hot water storage tank, as domestic hot-water, or is used as heating winter.Whole Hydraulic Power System is closed cycle system, and configuration moisturizing, exhaust apparatus, and expansion drum, maintain system pressure steady.
Cold night, the temperature in source, ground is higher than the temperature of solar panels, run first, second circulating pump, bring coldplate by the heat in source, ground by recirculated water continuously, heat to solar panels, maintain solar panels and do not freeze, pipeline is not freezing, and keep solar panels to possess preheat temperature, thus make solar panels can reach 30 DEG C sooner in the morning, enter best power generation operation state.
As shown in Figure 4, native system can upper and lower each series connection 8 pieces of solar panels, form upper and lower two cooling units, and each cooling unit adopts and connects with journey, and from left to right the distance of every block plate current is identical.
