Abstract
The utility model relates to a photovoltaic terminal box casing of trilateral ventilation in bottom, it includes casing body (1), form chamber (2) that hold that can hold metallic conductor and diode in casing body (1), its characterized in that: the heat dissipation device is characterized in that a vent (3) is formed between the bottom plate of the accommodating cavity (2) and the two side plates and the lower plate, the vent (3) is communicated with the back of the shell body (1) to form a heat dissipation channel (4), and the heat dissipation channel (4) enables the shell body (1) and the back plate to be suspended in the air. The junction box greatly improves the heat dissipation efficiency of the junction box, and avoids the burning failure of the photovoltaic module backboard caused by high temperature.
Description
Technical field
This utility model one rosette, especially relates to a kind of photovoltaic ventilated for three, the bottom of field of solar energy
Terminal block housings.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.
Utility model content
Technical problem to be solved in the utility model provides the ventilation of three, a kind of bottom for above-mentioned prior art
Photovoltaic junction box housing, increases substantially the radiating efficiency of rosette, it is to avoid high temperature makes photovoltaic component back plate burn inefficacy.
The technical scheme in the invention for solving the above technical problem is: the photovoltaic junction box that three, a kind of bottom ventilates
Housing, it includes enclosure body, forms the receiving chamber that can accommodate metallic conductor and diode in described enclosure body, and its feature exists
In: offering vent between base plate and biside plate and the lower plate in described receiving chamber, described vent is in enclosure body back side phase
Intercommunicated formation heat dissipation channel, described heat dissipation channel makes between enclosure body and backboard the most unsettled.
Compared with prior art, the utility model has the advantage of:
During using in order to avoid rosette, because of diode operational heat, bottom is made to become through rosette bottom heat transfer
Shape 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 sky
Gas convection current, increases substantially the radiating efficiency of rosette, simultaneously bottom unsettled ensure that rosette bottom section and light with backboard
Photovoltaic assembly backboard is not directly contacted with, thus avoids high temperature to make photovoltaic component back plate burn inefficacy.Additionally open on three sides is prevented effectively from
The foreign material such as rainwater, sand accumulations at unsettled place bottom rosette, rainwater, sand etc. enter wiring by both sides, side opening
Can be discharged under gravity by a following opening while the unsettled place of box, add rosette in desert etc. extreme ring
The reliability that border uses.
Accompanying drawing explanation
Fig. 1 is the structural representation in this utility model embodiment middle shell front.
Fig. 2 is the structural representation at this utility model embodiment middle shell back side.
Wherein:
Enclosure body 1, receiving chamber 2, vent 3, heat dissipation channel 4.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Seeing shown in Fig. 1 Fig. 2, the photovoltaic junction box housing that three, a kind of bottom in the present embodiment ventilates, including shell
Body body 1, forms the receiving chamber 2 that can accommodate metallic conductor and diode, the base plate in described receiving chamber 2 in described enclosure body 1
And offering vent 3 between biside plate and lower plate, described vent 3 is interconnected at enclosure body 1 back side, and being formed dispels the heat leads to
Road 4, described heat dissipation channel 4 makes between enclosure body 1 and backboard the most unsettled.
In addition to the implementation, this utility model also includes other embodiments, all employing equivalents or equivalence
The technical scheme that substitute mode is formed, within all should falling into this utility model scope of the claims.
Claims (1)
1. the photovoltaic junction box housing that three, bottom ventilates, it includes enclosure body (1), described enclosure body (1) interior shape
One-tenth can accommodate the receiving chamber (2) of metallic conductor and diode, it is characterised in that: the base plate of described receiving chamber (2) and biside plate and
Offering vent (3) between lower plate, described vent (3) is interconnected at enclosure body (1) back side formation heat dissipation channel
(4), described heat dissipation channel (4) makes between enclosure body (1) and backboard the most unsettled.
