Abstract
The utility model discloses a rapid cooling structure for a photovoltaic junction box. The rapid cooling structure includes a base and an upper cover which are mutually covered. A bottom plate is installed in the base, and terminals are installed on the base. A belt clip and a diode are installed on each terminal. Photovoltaic cables pass through wire pressing buckles installed in the base and are connected with the terminals. According to the utility model, the periphery of the base is bent to form hoardings and empty cavities are formed through the hoardings, so that the cooling is sped up; protrusive boards are added to the edges of the terminals and serve to enlarge the cooling area; and since the surface of the upper cover is designed to be convex, the interior space of the photovoltaic junction box is effectively enlarged, and the design of vents also facilitates the improvement of the cooling performance.
Description
Technical field
The utility model relates to field of photovoltaic power generation, relates in particular to a kind of heat dissipation structure that is applied to the photovoltaic junction box in photovoltaic generating system.
Background technology
In the electric connection technology of photovoltaic generating system, conventionally adopt photovoltaic junction box to realize the electrical connection between photovoltaic module and inverter.Current photovoltaic junction box, is all that installation cavity is set between box body, and diode is arranged in installation cavity.Because diode can produce higher temperature when working, along with the continuous rising of diode temperature, the resistance in diode will constantly increase, and cause diode to produce more heat, thereby waste more electric power resource, enter vicious circle.In order to guarantee that photovoltaic junction box has better thermal diffusivity, the general method that increases installation cavity volume in photovoltaic junction box that adopts, thereby increased thickness and the volume of whole photovoltaic junction box, the more important thing is, adopted and be difficult in this way the radiating effect that reaches good.Therefore, how to make photovoltaic junction box there is good heat dissipation ventilation effect, become the focus of industry research.
Utility model content
The purpose of this utility model is to provide a kind of heat dissipation structure of photovoltaic junction box, by integral heat sink characteristics design, realizes photovoltaic junction box cross-ventilation, flash heat transfer, reaches internal heat balance and protects diode, makes product have higher reliability.
The technical solution of the utility model is as follows:
A heat dissipation structure for photovoltaic junction box, comprises the base and the upper cover that mutually cover, in described base, base plate is installed, and a plurality of terminals are installed on described base plate, on each terminal, is separately installed with strap clamp, between each terminal, diode is installed; Photovoltaic cable is connected with terminal through the Line pressing buckle being arranged in base; It is crooked along base plate shape and perpendicular to the coaming plate of base end face that described base periphery is provided with; On described base, there are a plurality of cavitys that surrounded by coaming plate; The edge of described terminal has the flange perpendicular to terminal bottom surface, and the flange of described terminal contacts with the coaming plate of base; Described upper cover top surface has projection upwards, and the end face of described upper cover and side have a plurality of ventilation holes corresponding with empty cavity position on base.
Useful technique effect of the present utility model is:
The utility model, on hot speciality is optimized, by base periphery is bent to form to coaming plate, and forms a plurality of cavitys by coaming plate, and heat radiation is accelerated; By increasing the flange of terminal edge, play the effect that increases area of dissipation; By the design of upper cover surface convex, effectively increased photovoltaic junction box inner space, the design of ventilation hole, is also conducive to the raising of heat dispersion.
Advantage of the present utility model will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present utility model.

Fig. 1 is exploded view of the present utility model.
Fig. 2 is superstructure figure of the present utility model.
Fig. 3 is terminal structure figure of the present utility model.
Fig. 4 is understructure figure of the present utility model.
Fig. 5 is cut-away view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, the utility model comprises base 6 and the upper cover 1 mutually covering, and base plate 5 is installed in base 6, and difform a plurality of terminal 4 is installed on base plate 5, a plurality of strap clamps 2 and a plurality of diode 3.See Fig. 5, mounting means is that diode 3 is installed between terminals of adjacent 4, on each terminal 4, strap clamp 2 is installed respectively; Two pins of diode 3 are welded on two adjacent terminals 4, and terminal 4 is installed on base plate 5, and base plate 5 is installed to again on base 6.As shown in Figure 1, two Line pressing buckles 7 are arranged in base 6, and two strands of photovoltaic cables 8 weld through Line pressing buckle 7 and with terminal 4 respectively.If the utility model is encapsulating type, in base 6, in the space above base plate 5, pour into fluid sealant.
As shown in Figure 4, base 6 peripheries are provided with crooked along base plate 5 shapes and perpendicular to the coaming plate 6-1 of base 6 bottom surfaces, the encirclement to fluid sealant when coaming plate 6-1 can be used for encapsulating.On base 6, also have by coaming plate 6-1 and connect rear formed a plurality of cavity 6-2, the position of cavity 6-2, without encapsulating, has reduced encapsulating amount, has saved cost, and cavity 6-2 can make again heat radiation faster simultaneously, kills two birds with one stone.
Again as shown in Figure 3, the edge of terminal 4 has the flange 4-1 perpendicular to terminal 4 bottom surfaces, and during installation, the flange 4-1 of terminal 4 and the coaming plate 6-1 of base 6 contact, can increasing heat radiation area.
In addition, as shown in Figure 2, upper cover 1 end face has protruding 1-1 upwards, has effectively increased box body inner space, is also conducive to the raising of heat dispersion; Meanwhile, the end face of upper cover 1 and side have a plurality of ventilation hole 1-2s corresponding with cavity 6-2 position on base 6, can form the inside and outside cross-ventilation of box body, play the effect of radiating and cooling.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite that does not depart from spirit of the present utility model and design, within all should thinking and being included in protection range of the present utility model.
