Abstract
Disclosed in the utility model is a photovoltaic junction box comprising a box body. A diode module group and a circuit board are arranged in the box body; a radiator is embedded to the outer surface of the box body; and the diode module group arranged in the box body is contacted to and attached to the back side of the radiator and is electrically connected with copper conductors at the circuit board. According to the scheme, the diode module group enables all diodes to be integrated together and to be contacted to the back of the radiator outside the box body; the copper conductors welded with the diode module group only play a role in electric connection, so that the dimensions of the copper conductors and the junction box are substantially reduced. Meanwhile, the cooling effect of the junction box is also improved.
Description
Technical field:
The utility model relates to solar photovoltaic assembly technical field, especially relates to a kind of photovoltaic terminal box.
Background technology:
The status of photovoltaic terminal box in solar components is extremely important, and its Main Function is that the electric power that solar cell is produced is connected with outside line.Along with photovoltaic industry development with rapid changepl. never-ending changes and improvements, increasing sight has turned to it terminal box, because its electric power that solar cell can not only be produced is transferred in external circuit and goes easily, can also play effective protective effect to solar module simultaneously.
At present, photovoltaic industry generally uses and disperses diode fabrication terminal box, is provided with large-area copper conductor in junction box body, and diode and copper conductor weld together, and the energy receiving in terminal box is derived through cable.In actual use, when solar module absorbs solar power generation work, have electric current through diode, make diode produce heat, if can not timely and effectively these heats be derived and be scattered and disappeared, through long time integration, can make the temperature of terminal box raise, if exceed the resistance to extreme temperature of device in terminal box, will damage device and terminal box, and then cause photovoltaic module to damage.Because copper conductor also needs to have thermolysis except playing the effect of conduction, therefore copper conductor sectional dimension is larger, causes terminal box not only to have the problem oversize, manufacturing process is complicated, and radiating effect is also desirable not to the utmost.
Utility model content:
The purpose of this utility model be for prior art exist weak point and a kind of new photovoltaic junction box is provided, it have simple and compact for structure, size is less, the feature of good heat dissipation effect.
For achieving the above object, photovoltaic junction box of the present utility model includes box body, is provided with diode modules and wiring board in box body, and described cartridge outer surface is inlaid with radiator, the diode modules that is positioned at box body is attached at the radiator back side, and is electrically connected with the copper conductor on wiring board.
As technique scheme preferably, described radiator is undulatory aluminum material.
As technique scheme preferably, described diode modules is made up of the diode of metal backing, insulation crust and three series connection, wherein, the leg of diode stretches out in outside insulation crust, and welds together with copper conductor.
As technique scheme preferably, three diodes of described diode modules are laterally and column distribution, identical with copper conductor quantity and the leg of the leg welding of diode, are also laterally and column distribution, have weld part bottom each copper conductor.
As technique scheme preferably, the metal backing both sides of described diode modules are provided with installing hole, diode modules is connected with radiator via the bolt through installing hole.
As technique scheme preferably, described box body both sides have respectively outward-dipping wire connecting portion, external from wire connecting portion outlet box with the coarctate cable of copper conductor riveting.
The beneficial effects of the utility model are: diode modules integrates each diode, and be attached at the radiator back side of box body outside, the copper conductor welding together with the diode modules connection function that only electrifies, the size of copper conductor and terminal box is greatly reduced, also improved the radiating effect of terminal box simultaneously.
