The all-glue-pouring photovoltaic connecting box comprises an upper cover (1), a shell (2), a metal conductor (3) and a diode (4). The diode (4) is installed at the back surface of the metal conductor (3). An accommodating cavity (5) capable of accommodating the metal conductor (3) and the diode (4) is formed in the shell (2). The metal conductor (3) is installed on a positioning column (6) arranged at the baseplate of the accommodating cavity (5). The baseplate of the accommodating cavity (5) arranged exactly below the diode (4) is provided with a sink groove (7). A heat-radiating channel (8) of which the three sides surround the sink groove (7) is formed at the back surface of the shell (2). A ventilation opening (9) communicated with the heat-radiating channel (8) is arranged between the baseplate and the two side plates and the lower plate of the accommodating cavity (5). According to the connecting box, the heat radiation efficiency of the connecting box can be greatly enhanced and burnout and failure of the backboard of a photovoltaic component caused by high temperature can be avoided.

Description

Three, bottom ventilates and internal body diodes is inverted unsettled full encapsulating photovoltaic junction box
Technical field
One rosette of the present invention, especially relates to a kind of full encapsulating photovoltaic junction box unsettled for the ventilation of three, the bottom of field of solar energy and internal body diodes inversion.Belong to field of photovoltaic technology.
Background technology
At present, in the electric connection technology of solar power system, solar photovoltaic cell junction box is generally used to realize the electrical connection between photovoltaic module and inverter, photovoltaic junction box is bonded together with backboard by silica gel, during photovoltaic cell junction box work, diode can produce substantial amounts of heat, conventional photovoltaic battery connecting box bottom section directly contacts with photovoltaic component back plate at present, and heat can make the deformation of rosette bottom section and photovoltaic component back plate be affected by high temperature and burn and lost efficacy by the way of heat transfer.
In addition conventional photovoltaic battery connecting box carries out sealing waterproof and heat conduction by fluid sealant in rosette, diode in rosette cavity is mounted in the top of metallic conductor, and metallic conductor is directly fitted with housing bottom, adopts rosette in this way and has the disadvantage that
1, diode and metallic conductor only have top to have fluid sealant, bottom to still suffer from the possibility that rainwater penetrates into, and affect the electric property of rosette
2, conductor directly contacts box body, cannot be dispelled the heat by fluid sealant at diode operation adstante febre, causes box body to deform, and the heat dispersion of rosette can be affected significantly, the final life-span affecting whole rosette and performance.
Summary of the invention
The technical problem to be solved is to provide, for above-mentioned prior art, the full encapsulating photovoltaic junction box that three, a kind of bottom ventilates and internal body diodes inversion is unsettled, increases substantially the radiating efficiency of rosette, it is to avoid high temperature makes photovoltaic component back plate burn inefficacy.
nullThe present invention solves the technical scheme that the problems referred to above are used: three, a kind of bottom ventilates and internal body diodes is inverted unsettled full encapsulating photovoltaic junction box,It includes the upper cover that can mutually snap together and housing and metallic conductor、Diode and cable,Described cable is installed on the both sides, bottom of housing by wire pressing block,It is characterized in that: described diode is installed on the back side of metallic conductor,And the face down of diode,The receiving chamber that can accommodate metallic conductor and diode is formed in described housing,Described metallic conductor is arranged in the locating dowel accommodating chamber base plate,Sunk type groove is offered on receiving chamber base plate immediately below described diode,Three heat dissipation channels around sunk type groove are formed at the back side of described housing,The base plate in described receiving chamber with offer the vent being connected with heat dissipation channel between biside plate and lower plate.
Preferably, the scope of described sunk type groove is more than the size after whole metallic conductor and diode combination, and this sunk type groove makes metallic conductor and diode be in vacant state.
Compared with prior art, it is an advantage of the current invention that:
1, during using in order to avoid rosette, because of diode operational heat, make deformation of bottom and photovoltaic component back plate be affected by high temperature through rosette bottom heat transfer and burn and lost efficacy.Rosette of the present invention uses three Design of ventilation, increase cross-ventilation, increase substantially the radiating efficiency of rosette, simultaneously bottom unsettled ensure that rosette bottom section is not directly contacted with photovoltaic component back plate with backboard, thus avoid high temperature to make photovoltaic component back plate burn inefficacy.Additionally open on three sides effectively prevent the accumulation at unsettled place bottom rosette of the foreign material such as rainwater, sand, rainwater, sand etc. are entered by both sides, side opening and can be discharged under gravity by a following opening while the unsettled place of rosette, add the rosette reliability that extreme environment uses in desert etc..
2, in order to ensure sealing and the heat conduction of rosette, fluid sealant need to be by fully wrapped around to diode and metallic conductor, do not affect rosette whole height and bottom unsettled in the case of, this structure need to use the anti-assembling structure of diode, by support column, conductor is unsettled with diode, so that diode can be fully wrapped around by fluid sealant with metallic conductor, thoroughly conductor is sealed.Unsettled rear conductor is not directly contacted with bottom box body, will by fluid sealant quick conductive after diode operation heating, it is to avoid box body deformation.
