Problems solved by technology
Rooftop photovoltaic power plants place photovoltaic modules on the roof surface or the color steel tiles on the roof. Since the backlight surface of the photovoltaic modules is close to the color steel tiles / roof surface, it is difficult to dissipate heat. When the temperature of the photovoltaic modules rises and the heat cannot be dissipated in time It will affect the power generation efficiency of photovoltaic modules

The invention relates to the technical field of solar power generation, and discloses a heat dissipation device and a heat dissipation method of a photovoltaic module, and a photovoltaic power generation system. The heat dissipation device of the photovoltaic module comprises a water tank, a guide pipe and a first air bag, the water tank is arranged on the backlight side of the photovoltaic module, cooling liquid is contained in the water tank, the inlet end of the guide pipe is communicated with the water tank, the outlet end of the guide pipe extends to the position above the higher end of the light facing face of the photovoltaic module, and the first air bag is immersed in the cooling liquid. When the temperature of the cooling liquid rises to a preset temperature, the first air bag expands and enables the cooling liquid to be sprayed to the photovoltaic module from the outlet end. The heat dissipation device of the photovoltaic module has a good heat dissipation effect on the photovoltaic module, and the energy consumption in the heat dissipation process is low. According to the photovoltaic power generation system, the photovoltaic module heat dissipation device is arranged, so that heat can be dissipated in time, and the working stability is ensured. According to the heat dissipation method of the photovoltaic module, by arranging the heat dissipation device of the photovoltaic module, the heat dissipation effect on the photovoltaic module is good, and the energy consumption in the heat dissipation process is low.
Description
technical field [0001] The invention relates to the technical field of solar power generation, in particular to a heat dissipation device for a photovoltaic module, a heat dissipation method and a photovoltaic power generation system. Background technique [0002] Photovoltaic power generation is green, clean, environmentally friendly and low-carbon, so it has been widely used, including rooftop photovoltaic power plants. Rooftop photovoltaic power plants place photovoltaic modules on the roof surface or the color steel tiles on the roof. Since the backlight surface of the photovoltaic modules is close to the color steel tiles / roof surface, it is difficult to dissipate heat. When the temperature of the photovoltaic modules rises and the heat cannot be dissipated in time When it is out, it will affect the power generation efficiency of photovoltaic modules. [0003] Therefore, there is an urgent need for a heat dissipation device for photovoltaic modules to solve the above t...
