Description
Technical field
The present invention relates to a kind of photovoltaic industry photovoltaic cell component terminal box technical field, especially a kind of narrow heat dissipation of pipeline terminal box.
Background technology
At present, the radiating mode of Chang Gui photovoltaic module terminal box mostly is greatly by keeping air duct in junction box body surface increase fin, terminal box bottom and dispels the heat.But the heat dissipating method of said structure still can not reduce the temperature on diode surface in the terminal box effectively.
Summary of the invention
The technical problem to be solved in the present invention is: overcomes the deficiencies in the prior art, a kind of narrow heat dissipation of pipeline terminal box is provided, and the surface temperature in the time of effectively reducing diode operation in the terminal box, and then improve the operating efficiency of solar module.
The technical solution adopted for the present invention to solve the technical problems is: a kind of narrow heat dissipation of pipeline terminal box, has box body, box body is provided with the pipeline of at least one hollow, inner cavity of pipe communicates with outside air, pipeline outer wall communicates with the box body inner chamber, lower end of duct is equipped with the heat-conducting metal body, and heat-conducting metal body one side is connected with the body contact of diode, and heat-conducting metal body another side is connected with tube contacts.
Further, described heat-conducting metal body is wrapped in the lower end of duct outer surface.
Further, described heat-conducting metal body lower end has arc groove, and the body of described diode is embedded in the groove of heat-conducting metal body.
Further, described number of tubes is three, between adjacent two pipelines, be provided with sheet metal between pipeline and the inboard wall of cartridge, the lead-out wire at diode two ends is overlapped on respectively on the sheet metal of pipeline both sides, and the sheet metal between pipeline and the inboard wall of cartridge is connected with outer lead-out wire.
After the solar module that has a terminal box of the present invention was installed on the fixed mount, the last extreme direction of the pipeline among the present invention was for up.
The invention has the beneficial effects as follows: when the diode operation in the solar battery component junction box, the heat that sends is transferred on the pipeline by the heat-conducting metal body, and the air expanded by heating in the pipeline rises, utilize stack effect, hot-air is run out of from the pipeline upper end, thereby takes heat out of terminal box, and cold air is inhaled into owing to stack effect at lower end of duct, rise after in pipeline, being heated, so circulation reaches the purpose to diode radiating, thus the surface temperature when reducing diode operation.Temperature height during diode operation has negative effect to the generating efficiency of solar module, and therefore, the surface temperature of the present invention when reducing diode operation effectively improves the generating efficiency of solar module.
