Solar panel is to utilize photovoltaic effect solar radiation can be converted to the energy conversion device of electric energy, it is that the core group of photovoltaic electrical energy system becomes assembly, and the height of its energy conversion efficiency has directly determined performance, economic benefit and the popularizing application prospect of photovoltaic system.
According to Semiconductive Theory, the conversion efficiency of solar panel is subject to the impact of many factors, and wherein temperature factor is the most remarkable, and along with temperature raises, the conversion efficiency of solar panel significantly reduces until lost efficacy.Data show, the every rising 1K of temperature of cell panel, and its energy output just reduces 0.5%.But when terrestrial solar radiation intensity is better conventionally, the thermal effect of light is also fine, the temperature rise of cell panel is higher, and energy loss increases, and the energy loss of fairly large array (20～25 years) accumulation in whole life cycle is by considerable.
Can obviously find out from above, temperature factor is obviously disadvantageous on the impact of solar panel, or even fatal, and the impact that therefore reduces terrestrial solar radiation thermal effect by technological means just seems and is necessary very much.At present, utilization has source heat-dissipating or refrigeration modes can reduce the temperature of solar panel, and temperature is remained on to very low level, but the impact that reduces by the way terrestrial solar radiation thermal effect is lost more than gain, can be considerably beyond eliminating the electric energy increasing after terrestrial solar radiation thermal effect because achieve this end paid electric energy.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of solar panel cooling system, and it can lower the temperature to solar panel under the prerequisite not consuming energy.
Technical scheme of the present invention is as follows: the passive cooling system of a kind of solar panel, comprise solar panel (1), this solar panel (1) is inclined on battery board bracket (2), it is characterized in that: also comprise the assembly of lowering the temperature on the ground, underground heat exchanger assembly, the second tube connector (11) and the 3rd tube connector (12), the assembly of wherein lowering the temperature on the ground comprises air inlet pipe (3), refrigerator pipe (4), temperature lowering board (5), heating pipe (6), heat absorption blast pipe (7) and the first tube connector (8), wherein temperature lowering board (5) covers the back side of described solar panel (1), and temperature lowering board (5) was provided with gas endoporus (5a), described refrigerator pipe (4) is communicated with gas endoporus (5a) bottom of crossing of temperature lowering board (5), this top of crossing gas endoporus is communicated with described heating pipe (6), heating pipe (6) is communicated with heat absorption blast pipe (7) by described the first tube connector (8), and heat absorption blast pipe (7) is positioned at the top of described air inlet pipe (3),
