Abstract
The utility model discloses a ventilation-type photovoltaic junction box. The ventilation-type photovoltaic junction box comprises an upper box body and a lower box body, wherein the upper cover body is detachably connected with the lower box body; a sunken part is formed on the lower side surface of the lower box body; and a side ventilation opening and a vertical air hole are respectively formed in the lower box body and are respectively communicated with the sunken part and outside. By using the ventilation-type photovoltaic junction box, excess heat generated in the photovoltaic junction box can be radiated in time, so that photovoltaic elements are protected and the service life of the photovoltaic elements is prolonged.
Description
Technical field
The utility model relates to a kind of ventilated type photovoltaic junction box.
Background technology
Photovoltaic junction box is used for connecting solar module.But at present, existing photovoltaic junction box, its lower box body is plane, and directly contacts with photovoltaic back, is difficult for distributing with regard to the heat that causes producing in the photovoltaic wire box like this, influences the useful life of photovoltaic module and its inner photovoltaic element.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of ventilated type photovoltaic junction box, and this ventilated type photovoltaic junction box can in time distribute the unnecessary heat that produces in the photovoltaic junction box, and the protection photovoltaic element also improves its useful life.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of ventilated type photovoltaic junction box; Comprise upper cartridge body and lower box body; This upper cartridge body and lower box body are removably fixed with; On the downside of said lower box body, be formed with recess, on this lower box body, be respectively equipped with side ventilating opening and vertical air port in addition, this side ventilating opening is communicated with said recess respectively with vertical air port and is in communication with the outside.During use, lower box body contacts with photovoltaic back, and leaves certain space, and surrounding air can be carried out convection current with vertical air port through the side ventilating opening, thereby has taken away the heat that photovoltaic junction box produced, and reduces the temperature of photovoltaic junction box.
As the further improvement of the utility model, said side ventilating opening is symmetrically set on the dual-side of said lower box body, said vertical air port and vertical setting of said side ventilating opening, and this vertical air port also is symmetrical set, to guarantee the more unobstructed cross-ventilation that carries out.
The beneficial effect of the utility model is: through on the lower box body downside that makes the photovoltaic wire box recess being set; Make between photovoltaic wire box and the photovoltaic back and leave certain clearance; And through side ventilating opening and vertical air port and the extraneous circulative convection that carries out air; Thereby in time dissipate the unnecessary heat that produces in the photovoltaic wire box, protect its inner photovoltaic element, improve the useful life of photovoltaic element and photovoltaic wire box.

Embodiment
In conjunction with accompanying drawing, the utility model is elaborated, but the protection range of the utility model is not limited to following embodiment.
A kind of ventilated type photovoltaic junction box; Comprise upper cartridge body 1 and lower box body 2; This upper cartridge body and lower box body are removably fixed with; On the downside of said lower box body, be formed with recess 5, on this lower box body, be respectively equipped with side ventilating opening 3 and vertical air port 4 in addition, this side ventilating opening is communicated with said recess respectively with vertical air port and is in communication with the outside.During use, lower box body contacts with photovoltaic back, and leaves certain space, and surrounding air can be carried out convection current with vertical air port through the side ventilating opening, thereby has taken away the heat that photovoltaic junction box produced, and reduces the temperature of photovoltaic junction box.
Preferably, above-mentioned side ventilating opening is symmetrically set on the dual-side of said lower box body, said vertical air port and vertical setting of said side ventilating opening, and this vertical air port also is symmetrical set, to guarantee the more unobstructed cross-ventilation that carries out.
Claims (2)
1. ventilated type photovoltaic junction box; Comprise upper cartridge body (1) and lower box body (2); This upper cartridge body and lower box body are removably fixed with; It is characterized in that: on the downside of said lower box body, be formed with recess (5), on this lower box body, be respectively equipped with side ventilating opening (3) and vertical air port (4) in addition, this side ventilating opening is communicated with said recess respectively with vertical air port and is in communication with the outside.
2. ventilated type photovoltaic junction box according to claim 1 is characterized in that: said side ventilating opening is symmetrically set on the dual-side of said lower box body, said vertical air port and vertical setting of said side ventilating opening, and this vertical air port also is symmetrical set.
