[0003] However, the intelligent control module of the existing smart photovoltaic junction box is installed relatively close to the conductive plate and bypass diode. The heat generated by the bypass diode will cause the temperature of the surrounding environment to rise. The electronic components in the intelligent control module (such as integrated circuits, sensors, etc.) are very sensitive to temperature. Excessive temperature may cause the performance of these components to degrade or even be damaged. For example, the temperature increase may cause the resistance value of the electronic components to change, affecting the stability and reliability of the circuit, which urgently needs improvement.
