Photovoltaic junction box with heat dissipation structure

Abstract

The invention discloses a photovoltaic junction box with a heat dissipation structure, and the junction box comprises a photovoltaic junction box body. The top of the photovoltaic junction box body isprovided with a cover plate, and a contact part of the photovoltaic junction box body with the cover plate is provided with a first sealing strip. The bottom of the photovoltaic junction box body isprovided with a bottom plate, and the inner wall of the photovoltaic junction box body is provided with a cooling water layer. The left side wall of the photovoltaic junction box body is provided witha water incoming pipe which is communicated with the cooling water layer. The right side wall of the photovoltaic junction box body is provided with a water outgoing pipe communicated with the cooling water layer. The left and right side walls of the interior of the photovoltaic junction box body are respectively provided with a thermal conduction piece, and the thermal conduction pieces are arranged uniformly. The left and right sides of the bottom of the photovoltaic junction box body are symmetrically provided with positioning frames. The junction box changes the structure of a conventional photovoltaic junction box, achieves the cooling of the photovoltaic junction box body through a circulating water cooling method, is high in cooling efficiency, and prevents the overtemperature of the junction box from causing the instable performances.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a photovoltaic junction box with a heat dissipation structure. Background technique [0002] After 1870, with the widespread application of electricity, science and technology developed by leaps and bounds, and various new technologies and inventions emerged one after another, and were quickly applied to industrial production, greatly promoting economic development. With the continuous development of my country's economic construction and the acceleration of urbanization, electricity has become an indispensable part of people's production and life. At present, my country's main source of electricity is thermal power generation, which utilizes the heat energy generated during the combustion of solid, liquid, and gaseous fuels such as coal, oil, and natural gas, and converts it into electrical energy through power generation devices. With the rapid development of the nationa...
