Description
Technical field
The utility model relates to a kind of terminal box, especially relates to a kind ofly adopting diode (led) module plug in construction to carry out the terminal box of dispelling the heat for field of solar energy, belongs to field of photovoltaic technology.
Background technology
At present, in the electric connection technology of solar power system, usual employing solar photovoltaic cell junction box realizes the electrical connection between photovoltaic module and inverter, conventional photovoltaic cell junction box structure is form a conducting terminal installation cavity after upper cartridge body is connected with lower box body, by welding diode on conducting terminal, and this conducting terminal is arranged in chamber;
Consider the application scenario normally outdoor environment of photovoltaic cell junction box, therefore prevent the media such as rainwater from infiltrating terminal box thus affect the Consideration that inner electrical connection is an outbalance in terminal box design; For this reason in the hermetically-sealed construction of above-mentioned photovoltaic cell junction box, need to adopt the mode of encapsulating in conducting terminal installation cavity to seal, on sealing surface, cover tegillum after sealing again carry out covering and decorating;
Although the requirement of waterproof can be met after adopting above-mentioned hermetically-sealed construction, but production and processing is complicated, and diode and conducting terminal all need to adopt casting glue to seal, because the diode in photovoltaic cell junction box operationally can produce higher temperature, and along with the continuous rising of diode temperature, the impact that resistance in diode wafts due to temperature will constantly increase, diode is impelled to produce more heat further, diode in photovoltaic cell junction box conducting terminal installation cavity and metal terminal great majority are placed in conducting terminal installation cavity central authorities, the heat that diode produces all will be transmitted to box body by fluid sealant and then be dispersed in natural air, because medium heat conduction is very poor, conventional photovoltaic cell junction box all exists diode junction temperature height affects the phenomenon that performance even burns photovoltaic cell junction box, simultaneously, because the lower surface of the photovoltaic cell junction box of routine is directly fitted on battery back-sheet, too high temperature even can burn solar cell backboard when dispelling the heat in time, have a strong impact on photovoltaic plant normally to run, hinder the paces that solar panel develops to high-power.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of diode (led) module plug in construction to carry out the terminal box of dispelling the heat, and while simplification terminal box mounting means, improves the radiating effect of terminal box further.
The purpose of this utility model is achieved in that a kind of diode (led) module plug-in type photovoltaic cell junction box, it includes and is arranged at box body on photovoltaic cell backplane and packaged diode (led) module, there is in described box body the cavity of an accommodation diode (led) module, described diode (led) module is inserted in box body, be encapsulated in the cavity of box body by backboard by diode (led) module, the upper and lower surface of described diode (led) module and the internal face of box body fit tightly.
Described diode (led) module is close between the outer lower face surface of box body and photovoltaic cell backplane and is formed bridge-type aeration structure, and upper outer surface adopts heat radiation strength to strengthen heat radiation simultaneously.
Described backboard has two pieces, and one piece of cavity being positioned at box body, another block is positioned on the cavity hatch of box body, and carries out sealant pouring and sealing between two pieces of backboards.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is designed by diode (led) module plug-in type, and make assembling more simple, modular design makes diode better tightness, and diode packaging material conductive coefficient is high, by closely cooperating with box body, can directly heat be derived, temperature in box body is reduced, strengthens fail safe.

Embodiment
See Fig. 1-3, the utility model relates to a kind of diode (led) module plug-in type photovoltaic cell junction box, include and be arranged at box body 2 on photovoltaic cell backplane 8 and packaged diode (led) module 3, there is in described box body 2 cavity of an accommodation diode (led) module 3, described diode (led) module 3 is inserted in box body 2, by backboard 4, diode (led) module 3 is encapsulated in the cavity of box body 2, and by encapsulating mode, diode (led) module is sealed, it is outer and be connected with plug 6 that the cable of described diode (led) module 35 leads to box body 2 through backboard 4;
In order to reduce encapsulating amount, can arrange the cavity that two pieces of parallel backboards 4, a piece are positioned at box body 2, another block is positioned on the cavity hatch of box body 2, between two pieces of backboards 4, then carries out encapsulating can realize the hermetically sealed of diode (led) module 3;
The upper and lower surface of described diode (led) module 3 and the internal face of box body 2 fit tightly, and the heat that such diode (led) module 3 produces directly can be dispelled the heat by box body 2, in the front upper surface of described box body 2, a tegillum 1 is housed, for blocking and decoration.
In order to improve the radiating effect of terminal box further, being close between the outer lower face surface of box body 2 and photovoltaic cell backplane 8 forming bridge-type aeration structure at described diode (led) module 3, upper outer surface adopts heat radiation strength to strengthen heat radiation simultaneously; And can carry out air-cooled fast, better benefit to heat by the air channel formed between photovoltaic cell backplane 8 to be, the heating part of box body 2 no longer contacts with photovoltaic cell backplane 8, and therefore its high temperature can not produce any harmful effect to photovoltaic cell backplane 8.
