The invention discloses a cooling mechanism of a photovoltaic power generation panel and a cooling method thereof, and solves the problem of how to effectively cool the photovoltaic power generation panel. The cooling mechanism of the photovoltaic power generation panel comprises a photovoltaic power generation panel (1), a cuboid-shaped frame (2) and a heat dissipation panel (16). Right-angled trapezoidal fin plates are hinged to the left side surface and the right side surface of the cuboid-shaped frame (2) and the shape like two rows of wings of dragonflies which are arranged in two groupsat intervals in each row of wings; when the first group is lifted at a horizontal position, the other group is in a drooping state, and the two groups regularly exchange position states so that heat on the photovoltaic power generation panel (1) is firstly conducted to the group of right-angled trapezoidal fin plates in the horizontal state and then the group of right-angled trapezoidal fin platesabsorbing the heat are converted into the drooping state, the heat on the right-angled trapezoidal fin plates is conducted to the horizontal heat dissipation plate (16), and the horizontal heat dissipation plate (16) conducts the heat to the surrounding air by virtue of the large heat dissipation area of the horizontal heat dissipation plate. The device is simple and practical, and the photovoltaic power generation efficiency is improved.
Description
technical field [0001] The invention relates to a photovoltaic power generation device, in particular to a mechanism for cooling a photovoltaic power generation panel in summer. Background technique [0002] In a photovoltaic power generation system, when a photovoltaic power generation panel absorbs solar power, the temperature of the photovoltaic power generation panel itself will rise sharply, especially in summer. Therefore, effective cooling of photovoltaic power generation panels is one of the main means to improve the power generation efficiency of photovoltaic power generation panels; at present, the cooling of photovoltaic power generation panels is generally done on the back plate Fixed metal ribs are set to absorb the heat of the photovoltaic power generation panel through the metal ribs. However, when the ambient temperature is high, the metal ribs cannot dissipate heat in time after absorbing heat, resulting in poor cooling effect and affecting the power generat...
