Abstract
The invention discloses a junction box of a photovoltaic cell. The junction box comprises a box; a plurality of conducting strips are arranged in the box; and each of the two adjacent conducting strips are connected by a diode. A separator plate is arranged in the box and divides the box into a front chamber and a back chamber. And the conducting strips pass through the separator plate; one end of each of the conducting strip is at the front chamber, wherein the one end is connected with a bus bar; and the other end of each of the conducting strip is at the back chamber, wherein the other end is connected with one of the diodes. Besides, the bottom of the back chamber of the box is in an enclosed structure and a heat-conducting adhesive is perfused. Moreover, the junction box also includes a base plate that is connected under the box by a connecting piece. According to the invention, heat generated by a diode can be effectively radiated; meanwhile, when the diode is damaged, a junction box can be replaced conveniently without damage on a solar module.
Description
Technical field
The present invention relates to a kind of photovoltaic cell junction box, comprise box body, be provided with plurality of conducting strips in the box body, link to each other with diode between per two adjacent conductive sheets.
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 photovoltaic cell junction 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.During terminal box work, key component diode wherein can produce heat, distributes if heat is untimely, will have influence on the life-span of terminal box.The Chinese patent publication number is 201717276 to disclose the terminal box that a kind of diode heat conduction and heat radiation is handled; Its diode top is provided with the heat conduction section bar; When the diode adstante febre; Heat can be transferred to the heat sink section bar of box body outer setting through the heat conduction section bar, in this way diode is carried out radiating treatment.But its shortcoming is the heat that diode produces can all be dispersed on the heat sink section bar through the heat conduction section bar, and having quite a few still to be full of in box body can't distribute.In addition, it is inside and outside that heat sink section bar and heat conduction section bar are installed at box, in case come off from box body, just can't reach the radiating effect of expection.
For this reason, the someone expects following technical scheme, is about to heat-conducting glue and is poured in the terminal box, and the heat of diode generation will distribute through heat-conducting glue like this.After adopting this structure; The diode radiating performance strengthens, and is to be fixedly installed togather with solar module but its shortcoming is a terminal box, when diode damages; Since the diode circumfusion heat-conducting glue; People can't take out diode in box body, can only terminal box be pulled down from solar module by force, can cause solar module impaired like this.
Summary of the invention
The technical problem that the present invention will solve provides a kind of photovoltaic cell junction box, not only can effectively distribute the heat that diode produces, and when diode damages, can be convenient for changing terminal box simultaneously, can not damage solar module.
For this reason, the technical scheme of the present invention's employing is such: photovoltaic cell junction box comprises box body; Be provided with plurality of conducting strips in the box body, link to each other with diode between per two adjacent conductive sheets, be provided with dividing plate in the box body; Box body is divided into ante-chamber and back cavity; Conducting strip passes dividing plate, and an end that is connected with busbar is positioned at ante-chamber, and an end that is connected with diode is positioned at back cavity; The box body bottom of back cavity is closed, is perfused with heat-conducting glue; It also comprises a base plate, is connected under the box body through connector.
The present invention further improves, and the box body bottom of said ante-chamber has opening, and the position that said base plate is corresponding with ante-chamber also has opening.The connected mode of base plate and box body can be to be fastened and connected through fastener, also can be to connect with bolt, can also use chute-convex tendon to connect.
The present invention further improves, and has at least four fasteners on the said base plate.
The present invention further improves, and said fastener is six, and wherein two are positioned at the base plate front end, and four are positioned at base plate rear end.
The present invention further improves, and said base plate and box body ante-chamber cooperation place have seal washer.
The present invention further improves, and said seal washer is two.
Box body of the present invention is divided into ante-chamber and back cavity through dividing plate, and conducting strip passes dividing plate, and the conducting strip front end is positioned at ante-chamber, and the conducting strip rear end is positioned at back cavity; Do not pour into heat-conducting glue in the ante-chamber, ante-chamber mainly is provided with for connecting busbar, and the box body bottom of preferred ante-chamber has opening, can supply busbar therefrom to be inserted in the box body and be connected with the conducting strip front end; Be provided with diode in the back cavity; The conducting strip rear end links to each other with diode, and behind the perfusion heat-conducting glue, the heat that diode produces will all be dispersed in the heat-conducting glue in back cavity; Utilize the heat-conducting glue good heat-conducting; Be dispersed into the box body outside rapidly, adopt after this kind technical scheme, the terminal box radiating effect strengthens.Dividing plate makes heat-conducting glue can not get into ante-chamber, so busbar can not surround by heat-conducting glue, and busbar still can insert in the box body easily or in box body, take out.
Because back cavity has poured into heat-conducting glue; In case the phenomenon that diode damages takes place; Whole terminal box is just had no alternative but to comply and is removed replacing on the solar module, takes place for fear of this situation, the present invention includes a base plate; The base plate fixed bonding is on battery component, and box body is fastened and connected on base plate.If diode is damaged like this, the terminal box that need more renew, the box body that only needs to have the terminal box of diode is taken down from base plate and is got final product.For more convenient use, when the box body bottom of ante-chamber has opening, also have opening at the base plate corresponding position, can make things convenient for busbar to insert in the terminal box.
With base plate and box body bottom fastening the time, base plate is provided with preferred six fasteners, and wherein two are positioned at the base plate front end, and four rear ends that are evenly distributed on base plate are arranged, and makes that like this base plate and terminal box bottom fastens, sealing effectiveness is better.
Certainly, except above-mentioned fastener connects, also can select other connected modes for use, box body is connected with base plate such as bolt connection, chute connection etc.
In addition, in order to reach better sealing effectiveness, the present invention has increased seal washer at the base plate place corresponding to box body ante-chamber position, is preferably two, and it is tightr to make that base plate and box body combine.
