Description
Technical field
This utility model one rosette, especially relates to a kind of ventilation and internal for three, the bottom of field of solar energy
Unsettled full encapsulating photovoltaic junction box is inverted by diode.Belong to field of photovoltaic technology.
Background technology
At present, in the electric connection technology of solar power system, generally use solar photovoltaic cell junction box real
Existing electrical connection between photovoltaic module and inverter, photovoltaic junction box is bonded together with backboard by silica gel, and photovoltaic cell connects
During the work of line box, diode can produce substantial amounts of heat, and current conventional photovoltaic battery connecting box bottom section is carried on the back with photovoltaic module
Plate directly contacts, and heat can make the deformation of rosette bottom section and photovoltaic component back plate be affected by high temperature by the way of heat transfer
Burn and lost efficacy.
In addition conventional photovoltaic battery connecting box carries out sealing waterproof and heat conduction, rosette chamber by fluid sealant in rosette
Internal diode is mounted in the top of metallic conductor, and metallic conductor is directly fitted with housing bottom, uses this side
The rosette of formula 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 wiring
The electric property of box
2, conductor directly contacts box body, cannot be dispelled the heat by fluid sealant at diode operation adstante febre, causes box body to deform,
The heat dispersion of rosette can be affected significantly, the final life-span affecting whole rosette and performance.
Utility model content
Technical problem to be solved in the utility model be provide bottom one three to ventilate for above-mentioned prior art and
Internal body diodes is inverted unsettled full encapsulating photovoltaic junction box, increases substantially the radiating efficiency of rosette, it is to avoid high temperature makes light
Photovoltaic assembly backboard burns inefficacy.
The technical scheme in the invention for solving the above technical problem is: bottom one, three ventilate and internal body diodes
Be inverted unsettled full encapsulating photovoltaic junction box, it include 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 characterised in that: described diode is installed
In the back side of metallic conductor, and the face down of diode, formed in described housing and can accommodate metallic conductor and diode
Accommodating chamber, described metallic conductor is arranged in the locating dowel accommodating chamber base plate, the receiving chamber base plate immediately below described diode
On offer sunk type groove, form three heat dissipation channels around sunk type grooves, described receiving at the back side of described housing
The vent being connected with heat dissipation channel is offered between the base plate in chamber with 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, under this
Heavy formula groove makes metallic conductor and diode be in vacant state.
Compared with prior art, the utility model has the advantage of:
1, during using in order to avoid rosette, because of diode operational heat, bottom is made through rosette bottom heat transfer
Deformation and photovoltaic component back plate are affected by high temperature and burn and lost efficacy.This utility model rosette uses three Design of ventilation, increases
Cross-ventilation, increases substantially the radiating efficiency of rosette, simultaneously bottom unsettled ensure that with backboard rosette bottom section with
Photovoltaic component back plate is not directly contacted with, thus avoids high temperature to make photovoltaic component back plate burn inefficacy.Additionally open on three sides is effectively kept away
Having exempted from 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 connect
Can be discharged under gravity by a following opening while the unsettled place of line box, add rosette extreme in desert etc.
The reliability that environment uses.
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, 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 will
Conductor is unsettled with diode, so that diode can be fully wrapped around by fluid sealant with metallic conductor, is thoroughly sealed by conductor.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.
