Abstract
The utility model discloses a liquid/gas filled photovoltaic junction box, which comprises an upper cover and a lower cover. The upper cover and the lower cover can exactly hermetically form a closed space, a plurality of diodes and conductive terminals are arranged in the closed space, the lower cover is provided with a liquid/gas filling port and an air exhaust port, and each of the liquid/gas filling port and the air exhaust port is provided with a liquid closing nut which enables the liquid/gas filling port and the air exhaust port to be in a closed state. The photovoltaic junction box enables redundant heat in a box body to be dispersed, terminals of the box body can be effectively protected from air contact, and the service life of the liquid/gas filled photovoltaic junction box is prolonged.
Description
Technical field
The utility model relates to and a kind of conversion of solar energy is become the accessory of the equipment of electric energy, relates in particular to a kind of liquid/gas photovoltaic junction box that fills.
Background technology
Solar energy is because it is pollution-free, and is inexhaustible and more and more receive people's favor.Region with abundant light supply particularly.Receive sunlight and convert it into electric energy through the solar module of arranging with matrix form; Photovoltaic junction box by being arranged on each piece solar module backboard is derived electric energy through cable; The electricity of deriving can directly be used; Also can utilize photovoltaic connector that the cable of drawing is connected in series; But produce the life-span that a large amount of heat energy influences terminal box and photovoltaic module during diode work in the photovoltaic junction box, and the back panel wiring terminal contacts for a long time with air, influence its normal function thereby be easy to generate aging phenomenon.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of liquid/gas photovoltaic junction box that fills, and this photovoltaic junction box can shed by the heat that box body is unnecessary, can effectively protect the box body binding post to contact without air simultaneously, improves its useful life.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of liquid/gas photovoltaic junction box that fills; Comprise loam cake and lower cover; Proper salable formation one confined space of this loam cake and lower cover; In this confined space, be provided with several diodes and conducting terminal, cover under said and be respectively equipped with topping up/gas port and air exhaust port, on this topping up/gas port and air exhaust port, be respectively equipped with in addition and close the liquid nut and can make said topping up/gas port and air exhaust port be in closed condition respectively.During use, at first open two and close the liquid nut, and in box body, charge into thermally conductive and electrically resistive liquid or gas such as nitrogen from topping up/gas port; After treating that gas in the box body is all discharged from air outlet, close and close the liquid nut on the air exhaust port, continue to fill liquid/gas; After treating to form malleation in the box body, close/gas, like this; The after-heat that diode produces in the photovoltaic junction box closes the liquid nut through thermally conductive and electrically resistive liquid/gas and two and passes to surrounding enviroment, thereby has guaranteed the normal temperature state of whole box body; Conducting terminal in the box body can not play oxidation resistant effect in extraneous oxygen contact at work yet simultaneously.
As the further improvement of the utility model, be provided with malleation in said topping up/gas port inboard and close film, and this malleation is closed film said topping up/gas port is closed when pressure is higher than the outer pressure of said terminal box in the said terminal box.Like this, when in box body, charging into thermally conductive and electrically resistive liquid or inert gas, when box body internal pressure during greater than ambient pressure, malleation is closed film and is closed, and topping up/gas port is closed, and then closes and close the liquid nut on it, can play and close automatically and double protection.
As the preferred version of the utility model, said topping up/gas port and air exhaust port are located at respectively on the relative both ends of the surface of said lower cover.
The beneficial effect of the utility model is: through topping up/gas port and air exhaust port are set on box body; In box body, charge into thermally conductive and electrically resistive liquid or gas then so that box body pressure greater than outside pressure, is closed topping up/gas port and air exhaust port, so then; But the time binding post in the box body do not contact in air; Prevent too fast wearing out, thermally conductive and electrically resistive liquid can be gone out the unnecessary heat diffusion that diode in the box produces simultaneously, improves the useful life of photovoltaic element.
