Abstract

The invention discloses a liquid-cooled photovoltaic cell junction box and a working method thereof. The junction box comprises an upper cover, a back plate, a wiring box, a liquid inlet pipe and a liquid outlet pipe. An upper cover is mounted on that back plate, and a wiring box is arrange on the back plate between the upper cover and the back plate; A liquid inlet pipe, a liquid outlet pipe anda liquid inlet pipe are respectively arrange on that upper and lower side of the upper cover, the liquid outlet pipe is a through hole on the upper cover, the liquid inlet pipe and the liquid outlet pipe penetrate the two side walls of the upper cover respectively; The upper cover comprises a wiring cover plate, a conductor cover plate and a conductor opening. A conductor cover plate is arranged below the wiring cover plate. The two conductor cover plates are respectively located at both ends of the wiring cover plate, and the conductor cover plate tilt towards the outside of the wiring coverplate. At that bottom side of the two conductor cover plate, two conductor openings are respectively arranged, and the conductor openings penetrate through the bottom side of the conductor cover plate; A liquid inlet pipe is arranged on the lead cover plate beside the lead opening; A liquid outlet pipe is arranged on that top side of the wiring cover plate. The invention has the characteristics ofsimple structure, fast installation, strong heat dissipation ability and low working temperature.

Description

technical field [0001] The invention relates to a liquid-cooled photovoltaic cell junction box, in particular to a liquid-cooled photovoltaic cell junction box with simple structure, quick installation, strong heat dissipation capability and low working temperature and a working method thereof. Background technique [0002] Photovoltaic cell junction box is used to connect the power generated by photovoltaic cells with external lines. At the same time, in the case of mismatching of photovoltaic cells, it acts as a bypass protection to ensure that the output of good cells will not be blocked due to poor cells. (barrel effect). [0003] The photovoltaic cell junction box has a connector composed of a box body, a diode, and a cable. The box body is the main part, including the box body, internal metal copper sheet, diode, box cover, etc., and the box body and the box cover are connected together to form a junction box. shell. At present, the photovoltaic cell junction boxes i...
