Technical Field

Under the economic background of energy shortage and environmental pollution, developing new energy gradually becomes an effective means for alleviating the problems, and solar energy becomes new energy with the greatest development prospect based on the advantages of universality, harmlessness and long term. As a core technology for using solar energy, the photovoltaic technology has the advantages of no pollution, low operation cost, minimum equipment maintenance and maximum power density during operation. However, the photovoltaic system also has the problem that the working temperature of the surface of the photovoltaic panel is too high due to untimely heat dissipation, and the conversion efficiency of the system is negatively influenced. The output power of the solar photovoltaic panel is reduced by 0.4 percent every time the solar photovoltaic panel rises by 1 ℃, and when the temperature exceeds the limit temperature, the aging rate of the silicon crystal cell is accelerated. The cooling research of photovoltaic panels is of great significance.
Although the traditional photovoltaic panel cooling technologies such as natural convection circulation cooling, forced convection circulation cooling and liquid cooling are convenient to operate and simple in system, the conversion efficiency and power of the photovoltaic panel are improved, the improvement range is not obvious enough, and the heat transfer resistance is still large. Although the novel photovoltaic cooling technologies such as floating tracking centralized cooling and phase-change material cooling can effectively improve the conversion efficiency of the photovoltaic panel, the system circulation stability of the photovoltaic panel can not meet the requirements of practical application. Therefore, the solar photovoltaic panel cooling device which is simple, effective and high in system circulation stability needs to be developed. And the refrigeration technology combined with solar heating drive is particularly feasible for radiating the photovoltaic panel.
Aiming at the refrigeration technology driven by solar heating, at present, two modes of solar absorption refrigeration and solar adsorption refrigeration are mainly adopted. The absorption refrigeration technology is not suitable for the heat dissipation of the solar photovoltaic panel due to the problems of low efficiency, power consumption, high noise, high cost and easy damage, and the adsorption refrigeration technology has the advantages of capability of utilizing a low-grade heat source, no moving parts, no noise, long service life and the like. However, since the adsorption refrigeration technology requires desorption and desorption, and there are refrigeration intervals, so that the refrigeration is discontinuous, and the cycle period is too long, which results in lower efficiency than other refrigeration methods, no feasible improvement method has been found at present.

Aiming at the defects of the existing solar photovoltaic panel cooling technology, the invention combines the characteristic that a solar adsorption type refrigeration mode can utilize a low-grade heat source, adopts a photo-thermal separation technology as the first-stage cooling, and utilizes a microemulsion improved adsorption type refrigeration technology to carry out the second-stage cooling on the solar photovoltaic panel, thereby providing a solar photovoltaic panel cooling device, improving the cooling effect of the photovoltaic panel and further improving the power generation efficiency of the solar panel.
The technical scheme adopted by the invention is as follows: the utility model provides a solar photovoltaic board cooling device which characterized in that: the system comprises a photo-thermal separation module, a heat collection module, a refrigeration and cold accumulation module and a microemulsion circulation module;
the photothermal separation module and the heat collection module are connected through a heat pipe, the heat collection module and the refrigeration and cold accumulation module are connected through a heat pipe, and the refrigeration and cold accumulation module and the microemulsion circulation module are connected through a first cooling air pipe and a second cooling air pipe;
