[0002] Photovoltaic panels generally refer to solar cells. Solar cells are photoelectric semiconductor sheets that use sunlight to generate electricity directly, also known as "solar chips" or "photovoltaic cells". As long as they are illuminated under certain illumination conditions, they can instantly output voltage and generate current in the presence of a circuit. When photovoltaic panels are exposed to high temperature for a long time, heat will be concentrated, making the operating temperature of the photovoltaic panels much higher than the surrounding ambient temperature, affecting the performance and service life of the photovoltaic power generation device. Therefore, a heat dissipation device is set to cool the photovoltaic panels. The position of the heat dissipation fan of the heat dissipation device is generally fixed, which is not conducive to the heat dissipation of different parts of the photovoltaic panels. Therefore, a heat dissipation device for photovoltaic panels is proposed to improve the heat dissipation effect. Utility Model Content
