Abstract
The utility model relates to a solar junction box with a heat sink, which comprises a box body and a diode and a conductive body in the box body. Outside the box body a heat sink is arranged. The heat sink and the box body are hermetically connected by the silicone rubber. The heat sink with the air convection is increased and the temperature of the diode is conducted to the heat sink through the insulating heat conduction, thus effectively reducing the temperature of the diode, greatly improving the stability and the reliability of the diode and providing the protection for the security of the solar power station. The heat sink of the solar junction box is directly mechanically fixed with the aluminum frame of the solar battery pack, by using the fixation method the time of the production flow is greatly shortened and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of solar junction box, especially refers to a kind of solar junction box with heat abstractor.
Background technology
The solar junction box of solar module use at present is to adopt bypass diode is enclosed in terminal box inside all, and the heat that diode distributes during work outwards conducts by terminal block housings, and there is following problem in the method:
1, because solar junction box need reach the purpose of safe insulation, so external shell all adopts the engineering plastics of anti-aging and function admirable to make, its temperature conduction is very poor.As shown in Figure 1.
2, with regard to present most of solar junction box product, diode is under the service condition of regulation, and its temperature is all near its limiting temperature.In actual use often because the diode operation temperature oversteps the extreme limit temperature damage, cause whole solar power station cisco unity malfunction, also can cause fire in the time of seriously, become a big potential safety hazard of solar power system.
3,, have only the electric conductor area that increases terminal box to help heat radiation, and, will make the volume of whole terminal box increase owing to increased the electric conductor area of terminal box in order to reach the purpose of cooling.
4, because the operating current of battery component is increasing, present conventional design scheme can not meet the demands.
5, the connected mode of terminal box and solar components adopts the fixing mode of glue of pasting fully now.Admittedly just can carry out next step flow process because this kind mode must be pasted gelling in process of production by the time, so operating efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of good heat dissipation, do not increase simultaneously the solar junction box of terminal box volume, the solar junction box of energy steady operation under the operational environment of big electric current, while simple installation, the solar junction box of raising installation effectiveness.
In order to solve the problems of the technologies described above, the utility model has adopted following structure, and a kind of solar junction box with heat abstractor comprises diode and electric conductor in box body and the box body, box body is equipped with heat abstractor outward, and heat abstractor is connected by silicone rubber seal with box body.
Described solar junction box with heat abstractor, heat abstractor is connected with the frame of solar module.
The beneficial effects of the utility model:
1, owing to having increased cross-ventilated heat abstractor is arranged, the temperature of diode is transmitted on the heat abstractor by insulating heat-conductive, effectively reduce the temperature of diode, improved the stability and the reliability of assembly greatly, fail safe provides guarantee to solar power station.
2, thereby dwindling of solar junction box volume solved because the excessive problem that reduces the assembly generating efficiency of volume of terminal box.
3, the connected mode of terminal box and solar components adopts the fixing mode of glue of pasting fully now.Because must pasting gelling in process of production by the time, this kind mode just can carry out next step flow process admittedly.And terminal box and aluminum frame of solar cell assembly direct mechanical are fixed in this programme, and this kind fixing means has shortened the production procedure time greatly, has improved production efficiency.
