Problems solved by technology
Since the diode will generate a higher temperature during operation, as the temperature of the diode continues to rise, the resistance in the diode will continue to increase, causing the diode to generate more heat, thereby wasting more power resources and entering a vicious cycle. To ensure that the photovoltaic junction box has better heat dissipation, the method of increasing the volume of the conductive sheet installation cavity in the photovoltaic junction box is generally used, thereby increasing the thickness and volume of the entire photovoltaic junction box. More importantly, it is difficult to achieve this by using this method. good cooling effect

Description
technical field [0001] The invention relates to the field of photovoltaic equipment, more specifically, to a photovoltaic junction box with high heat dissipation. Background technique [0002] In the electrical connection technology of solar power generation systems, solar photovoltaic junction boxes are usually used to realize the electrical connection between photovoltaic modules and inverters. [0003] A conductive sheet installation cavity is provided between the box cover and the base of the commonly used photovoltaic junction box at present, and the conductive sheet with the diode is installed in the conductive sheet installation cavity. Since the diode will generate a higher temperature during operation, as the temperature of the diode continues to rise, the resistance in the diode will continue to increase, causing the diode to generate more heat, thereby wasting more power resources and entering a vicious cycle. To ensure that the photovoltaic junction box has bett...
