Abstract
The utility model relates to a photovoltaic wire connection box. The photovoltaic wire connection box comprises a bottom box, and a box cover which is closed onto the bottom box. A cavity is formed between the bottom box and the box cover. A photovoltaic assembly is arranged on the bottom box, a through hole is formed in the bottom of the bottom box, and silica gel is injected into the cavity through the through hole. According to the utility model, by forming the through hole in the bottom of the wire connection box, the silica gel can be injected into the cavity in advance through the through hole, then heat dissipation is performed in the wire connection box through the silica gel, so the heat dissipation performance can be improved, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of photovoltaic terminal box.
Background technology
The heat dispersion of photovoltaic junction box is an important performance, if heat in time can not be distributed, the phenomenons such as quick-fried box will occur, all is by air heat conduction in the box in the prior art, and air heat conduction is slower.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of heat dispersion better photovoltaic junction box.
The technical scheme in the invention for solving the technical problem is:
A kind of photovoltaic junction box, comprise end box and the lid that covers on end box, be formed with cavity between box of the described end and the lid, be provided with photovoltaic module on the box of the described end, the bottom of box of the described end arranges a through hole, is injected with silica gel by through hole in the described cavity.
As preferably, the afterbody of the photovoltaic module arc fixture block that extended back, the cable access is in described arc fixture block and compacted.
In the bottom of end box one through hole is set, injects in advance silica gel by through hole in box body, then the heat of photovoltaic module generation conducts by silica gel, because the heat dispersion of silica gel is better, so the heat radiation of photovoltaic junction box is faster.Photovoltaic module arranges the arc fixture block, and cable compresses after putting into the arc fixture block again, and then cable has just connected.
The beneficial effects of the utility model are: the utility model arranges through hole in the terminal box bottom, can inject silica gel by through hole in advance, then dispels the heat by silica gel in the terminal box, has increased heat dispersion, has improved useful life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of photovoltaic module.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, 2, a kind of photovoltaic junction box comprises end box 2 and the lid that covers on end box, be formed with cavity between end box 2 and the lid, be provided with photovoltaic module 3 on the box of the described end, the bottom of box of the described end arranges a through hole 1, is injected with silica gel by through hole 1 in the described cavity.The afterbody of the photovoltaic module arc fixture block 4 that extended back, the cable access is also compacted described arc fixture block 4 in.
In the bottom of end box one through hole 1 is set, injects in advance silica gel by through hole in box body, then the heat of photovoltaic module generation conducts by silica gel, because the heat dispersion of silica gel is better, so the heat radiation of photovoltaic junction box is faster, has increased heat dispersion, has improved useful life.Photovoltaic module arranges the arc fixture block, and cable compresses after putting into the arc fixture block again, and then cable has just connected.
