Abstract
The utility model discloses a photovoltaic battery wiring box which comprises a box body, wherein a diode is fixedly arranged in the box body, a hollow part is arranged at the bottom of the box corresponding to the mounting position of the diode, heat radiating fins are arranged in the hollow part, and the number of the heat radiating fins is the same as that of the diode; and the diode is flat, the pin of the flat diode is fixedly connected with a conducting plate, and the heating part of the flat diode is tightly adhered to respective corresponding heat radiating fins. The utility model adopts the technical effect that the heat dispersion of the diode of the wiring box is greatly improved; meanwhile, the wiring box can be used as an independent product to be sold; in addition, the mounting position of the wiring box is not limited in the subassembly.
Description
Technical field
The utility model relates to a kind of photovoltaic cell junction box, comprises box body, and the box body internal fixation is equipped with diode.
Background technology
Along with the application of solar power generation is more and more general, also constantly weed out the old and bring forth the new with the closely-related terminal box of its application, many groups solar module that solar power generation adopts matrix form to arrange, convert daylight to electric energy, each group solar module is connected with terminal box, and terminal box is connected with other parts of solar power system again.Because the terminal box long-term work out of doors, the reasonability of Design of Mechanical Structure and the quality of quality are directly connected to the efficient of electrical transmission.
Diode is the key component in the photovoltaic cell junction box, and in use, diode can produce heat, distributes if these heats are untimely, can have influence on the life-span of diode, can not satisfy the electrical safety requirement simultaneously.In order to solve the heat dissipation problem of diode in the terminal box, adopt usually in the market fin is set in box body, but the heat that this mode makes diode produce at first distributes in box body, because box space is narrow and small, the temperature in the box body is still higher.For head it off, China utility model mandate publication number CN201514945 discloses a kind of solar module, wherein relate to termination, it as fin, directly supports the conducting strip that is provided with diode the frame of solar module be attached on the described frame and dispels the heat.The shortcoming of this structure is that the caloric requirement that diode produces is distributed to the frame of solar module through conducting strip again; Adopt in addition after this structure, the competence exertion effect that also terminal box and solar module must be fixed together is carried out production and sales with terminal box as independent product with regard to having limited like this.Except above-mentioned shortcoming, its termination also needs other jockey to protect busbar away from battery.
The utility model content
The technical problems to be solved in the utility model provides a kind of terminal box, both can be used as independent product and has carried out production and sales, also can effectively solve the bad problem of diode heat dissipation effect, and its installation site in solar module without limits in addition.
For this reason, the technical solution of the utility model is such: photovoltaic cell junction box, comprise box body, the box body internal fixation is equipped with diode, it is characterized in that: there is a hollow out position box body bottom corresponding to the installed position of diode, is provided with the fin that equates with number of diodes in this hollow out position; Described diode is flat diode, and its pin is fixedlyed connected with conducting strip, and its heating part is close on each self-corresponding fin.
The utility model further improves, and comprises bayonet unit, and the heating part of diode is close on the fin.
The utility model further improves, and box side wall offers some ventilating openings corresponding to the fin place.
In order to reach butted line box diode efficiently radiates heat, the utility model has been offered the hollow out position in the junction box body bottom, and below, hollow out position is provided with fin, and the quantity of fin is identical with number of diodes, the position correspondence.Diode pin and metallic conduction sheet are fixed, and when being fixed on conducting strip in the box body, the diode heating position just in time is in corresponding fin top, this hollow out position.By bayonet unit diode heating position and fin are close together, because diode is flat, its contact area with fin is big, makes its generation heat distribute by fin easily.Fin is fixed on the terminal box bottom.During terminal box work, at first, the fin transmission of heat major part that the diode heating produces by being close to it, secondly because several fin separate, the heat that makes diode send also can outwards transmit by the space between the fin.In order to dispel the heat better, on the terminal box box side wall, offer ventilating opening corresponding to the fin place, adopt after such structure, the residing position of fin air flow property strengthens, when cross-ventilation increases, when most of heat outwards transmitted by fin, some other heat can also outwards distribute by these ventilating openings, had also further improved radiating effect.
Adopt technique effect of the present utility model to be: the diode radiating performance of terminal box significantly improves, and the while terminal box can be used as independent product and sells, and its installation site in assembly is unrestricted in addition.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing and execution mode of the present utility model.
Fig. 1 is an explosive view of the present utility model.
Fig. 2 is the utility model diode and fin connection diagram.
Embodiment
Referring to Fig. 1 and Fig. 2.Terminal box box body 3 bottoms have hollow out position 5, and flat diode 4 quantity are 3, and diode 4 links to each other with metallic conduction sheet 6.By dotted line among Fig. 1 as can be known, when metallic conduction sheet 6 is fixed on the bottom of box body 3, the pin of diode 4 is fixedlyed connected with metallic conduction sheet 6, make diode 4 just in time be positioned at 5 places, hollow out position, 5 belows, hollow out position have 1,3 fin 1 of 3 fin and are close to by buckle 7 and corresponding diode 4.Offer ventilating opening 8 on the box side wall of box body 3 corresponding to hollow out position 5.Ventilating opening 8 can be several.
Claims (3)
1. photovoltaic cell junction box comprises box body, and the box body internal fixation is equipped with diode, it is characterized in that: there is a hollow out position box body bottom corresponding to the installed position of diode, is provided with the fin that equates with number of diodes in this hollow out position; Described diode is flat diode, and its pin is fixedlyed connected with conducting strip, and its heating part is close on each self-corresponding fin.
2. photovoltaic cell junction box as claimed in claim 1 is characterized in that: comprise bayonet unit, the heating part of diode is close on the fin.
