Besides, the area and the size of the junction box can be greatly reduced by the triangular structure, material consumption is less and internal glue pouring quantity is also greatly reduced so that manufacturing cost of the junction box can be greatly reduced and competitiveness of the product can be enhanced.
Description
Technical field
The present invention relates to solar-photovoltaic technology field, it is the photovoltaic component terminal box of triangular shape structure in particular to a kind of low cost.
Background technology
Increasingly serious along with Global climate change and problem of environmental pollution, green regenerative energy sources industry last decade is developed rapidly. Sun power is a kind of renewable resources, and the solar cell technology utilizing photogenic voltage effect to carry out generating electricity enjoys common people to pay close attention to. Solar cell is by the material that can produce photovoltaic effect, as the materials such as silicon, gallium arsenide, indium selenium copper are made, it is possible to light energy conversion is become electric energy. At present, the photovoltaic module combined by multi-disc solar cell is widely used for building various photovoltaic generating system, or for building up energy saving and environment friendly building as constructure screen wall.
In actual use, it is necessary to the electric energy using photovoltaic component terminal box to be produced by photovoltaic module is drawn and is connected with outside load. Therefore, photovoltaic component terminal box is the key part that photovoltaic module builds various power generation system. Generally being used the bypass diode of protection electrification component in terminal box, diode is a heater members, in order to ensure the work-ing life of terminal box, it is necessary to resolve the heat dissipation problem of terminal box inside. In addition, along with the fierceness all the more of market competition, the cost of terminal box is also the problem needing to consider. Current terminal box generally all adopts four square box structure, and the materials of the bigger material of area are more and need the glue amount of perfusion also bigger, and therefore cost of manufacture is higher.
Summary of the invention
It is an object of the invention to, for the consideration improving product competitiveness, it is provided that a kind of photovoltaic component terminal box being convenient to perfect heat-dissipating and low cost.
To achieve the object of the present invention, the present invention proposes the photovoltaic component terminal box of a kind of structure in triangular shape, comprise box body and cable link, the connection terminal that multiple solar battery convergent current bar with photovoltaic module is connected it is provided with in described box body, electrical connection is formed by chip diode between described connection terminal, described box body is triangular shape structure, and adjacent two side that described cable link constructs from triangular shape is drawn.
Preferably, three vertex angle parts of the photovoltaic component terminal box of described triangular shape structure are that chamfering is arranged.
Preferred again, the photovoltaic component terminal box of described triangular shape structure has two adjacent sides for waiting long setting, and described cable link waits long side to draw from two.
Preferred again, what two of the photovoltaic component terminal box of described triangular shape structure were adjacent waits long side to be that linear pattern is arranged or arc line type is arranged or broken-line type is arranged.
Preferred again, another side of the photovoltaic component terminal box of described triangular shape structure is that linear pattern or arc line type are arranged.
Preferred again, three sides of the photovoltaic component terminal box of described triangular shape structure etc. are long to be arranged.
Preferred again, three sides of the photovoltaic component terminal box of described triangular shape structure are arranged in inverted triangle on photovoltaic module, and a limit above is arranged in horizontal direction, and cable link is drawn from the side that two below are adjacent.
The photovoltaic component terminal box of the present invention adopts triangular shape structure, and structure is more compact, and heater members distance terminal box frame is nearer, and thermal diffusivity is good; In addition, triangular shape structure can significantly reduce area and the volume of terminal box, it may also be useful to material less, inner filling glue amount also greatly reduces, it is possible to make the manufacturing cost much slower of terminal box, it is to increase the competitive power of product.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the present invention aforesaid and other object, feature and advantage will become apparent. Wherein:
Fig. 1 show the structural representation of the photovoltaic component terminal box of the triangular shape structure of one embodiment of the invention.
Embodiment
By reference to the accompanying drawings the feature of the present invention and advantage are described in detail as follows.
With reference to the structural representation of the photovoltaic component terminal box that the triangular shape of the one embodiment of the invention shown in Fig. 1 constructs, described photovoltaic component terminal box comprises box body 10 and cable link 20, the connection terminal 12 that multiple solar battery convergent current bar with photovoltaic module is connected it is provided with in described box body 10, electrical connection is formed by chip diode 14 between described connection terminal, described box body 10 is triangular shape structure, adjacent two the side extraction that described cable link 20 constructs from triangular shape.
One preferred embodiment in, three vertex angle parts of photovoltaic component terminal box of described triangular shape structure are the setting of falling fillet. In addition, three sides of described photovoltaic component terminal box have two adjacent sides, if side 102,103 such as is at long the setting, described cable link 20 from then on two wait long side to draw.
Should be understood that, the terminal box of the present invention is triangular shape structure, do not refer to that terminal box is the triangular shape in strict meaning, such as, two of the photovoltaic component terminal box of the described triangular shape structure adjacent long sides that wait or can also be that broken-line type is arranged for arc line type setting for linear pattern is arranged; Another side of terminal box can also be that linear pattern or arc line type are arranged; The end angle of terminal box can arrange chamfering, and chamfering can be rounded corner can also be the chamfering of other shapes. Therefore, the profile that should be understood as terminal box roughly becomes triangular shape to construct, and is different from existing square structure.
Another preferred embodiment in, three sides 101,102,103 of photovoltaic component terminal box of described triangular shape structure such as are at long the setting, i.e. the structure in " equilateral " triangular shape.
When terminal box in the present invention is installed to the photovoltaic module back side, a kind of relatively good installation mode is that the photovoltaic component terminal box constructed by triangular shape is arranged in inverted triangle on photovoltaic module, a limit above is arranged in horizontal direction, and cable link is drawn from the side that two below are adjacent.Now, the described adjacent side of two below that is positioned at is wait long setting.
As mentioned above, it is necessary, the photovoltaic component terminal box of the present invention adopts triangular shape structure, structure is more compact, and heater members distance terminal box side frame is nearer, and thermal diffusivity is good; In addition, triangular shape structure can significantly reduce area and the volume of terminal box, the material used is less, when terminal box encapsulates, inner filling glue amount also greatly reduces, so can make the manufacturing cost much slower of terminal box, improve the competitive power of product when market competition is more and more harsher.
The present invention is not limited to described embodiment, and namely the technician of this area discloses in scope in the spirit not departing from the present invention, still can do some and revises or change, therefore the scope that the scope of the present invention limits with claim book is as the criterion.
