The utility model provides the pressing plate of a kind of solar module with single crystal growing furnace, realized under not extra situation about taking up room, and the probability that the high temperature silicon solution that reduction is leaked contacts with the single crystal growing furnace miscellaneous part, and then reduced the risk that single crystal growing furnace is blasted.The utility model also relates to a kind of solar module with above-mentioned pressing plate and uses single crystal growing furnace.
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Like Fig. 3 and shown in Figure 4, the solar module that the utility model embodiment provides comprises with the pressing plate of single crystal growing furnace:
Which is provided with respectively the pressing plate body 7 of the pressure pin hole 4, electrode hole 5 and the venting hole 6 that are passed by the crucible pressure pin 1 of single crystal growing furnace and electrode 2;
Be arranged on pressing plate body 7 external margins, and the first side wall 8 on protrusion pressing plate body 7 surfaces;
Be arranged on the edge of pressure pin hole 4, electrode hole 5 and venting hole 6; And protrusion pressing plate body 7 surfaces; Be positioned at lip-deep second sidewall 9 in the same side of pressing plate body 7 with the first side wall 8, be formed for the groove of the silicon solution 10 that splendid attire reveals between the first side wall 8 and second sidewall 9.
Please refer to accompanying drawing 5, the solar module that present embodiment provides is following with the working process of the pressing plate of single crystal growing furnace:
In a single day silicon takes place and leaks in single crystal growing furnace in the process of producing; Silicon solution 10 can flow on the pressing plate body 7 that is arranged on the single crystal growing furnace bottom; Because on the end face of the pressing plate body 7 that is passed by the crucible pressure pin 1 of single crystal growing furnace, electrode 2 and exhaust sheath 3; At the first side wall 8 at pressing plate body 7 edges and second sidewall 9 at pressure pin hole 4, electrode hole 5 and venting hole 6 edges, so silicon solution 10 can be stored in the groove of the first side wall 8, second sidewall 9 and 7 formation of pressing plate body.
Can draw through above-mentioned working process; In the pressing plate of the solar module that present embodiment provides with single crystal growing furnace; Through the first side wall 8 and second sidewall 9 are set on the end face of pressing plate body 7; Make it form the groove that to store silicon solution 10, so that silicon solution 10 other positions that flow to single crystal growing furnace still less with pressing plate body 7.Pressing plate body 7 is identical with the thickness of the graphite pressing plate of available technology adopting with the height sum of the first side wall 8, second sidewall 9; Promptly also can the groove that the first side wall 8, second sidewall 9 and pressing plate body 7 form be interpreted as on the surface of existing graphite pressing plate and dig out a groove; Therefore; Do not increasing miscellaneous part, not extra taking under the thermal field of single crystal furnace spatial prerequisite, the damages that reduce even avoided silicon solution 10 to melt the single crystal growing furnace miscellaneous part have also reduced water vapor and have got into the probability in the thermal field of single crystal furnace; Reduced the risk of blasting; Make production cost obtain reduction, simplified cleaning, the installation process of single crystal growing furnace, for bigger economic benefit has been won in the production of solar module.
In order further to optimize technique scheme, in the pressing plate of the solar module that present embodiment provides with single crystal growing furnace, the first side wall 8 and second sidewall 9 and pressing plate body 7 structure that is one of the forming.For the stability that increases whole pressing plate and the exactness of groove; Reduce the probability that silicon solution 10 flows out pressing plates, with the first side wall 8 and second sidewall 9 and pressing plate body 7 structure that is one of the forming, with the work-ing life of prolongation pressing plate; Farthest avoid the single crystal growing furnace miscellaneous part to receive the infringement of silicon solution 10; But production process has been simplified in integrated formed structure time processing moulding in process of production in addition greatly, has improved production efficiency.
Concrete, the first side wall 8 and second sidewall 9 and pressing plate body 7 are except above-mentioned mode of connection, and the first side wall 8 can also or link to each other with pressing plate body 7 through seal connector through the sealing welding with second sidewall 9.Certainly, under the prerequisite of solar module with the pressing plate works better of single crystal growing furnace that present embodiment provides, the first side wall 8 can also adopt other mode to be connected with second sidewall 9 and pressing plate body 7.
Preferably, the degree of depth of groove equates with the thickness of pressing plate body 7.The degree of depth that makes groove and the thickness of pressing plate body 7 equate it is under the identical prerequisite of the thickness that guarantees itself and existing graphite pressing plate; Farthest increase the volume of groove; This kind set-up mode has satisfied self mechanics requirement of whole pressing plate preferably, and structure is more reasonable, and its work-ing life can be longer; So consider at the same time and satisfy the requirement of pressing plate self structure and increase under the groove volumetrical situation to greatest extent, be set at the degree of depth that forms groove identical with the thickness of pressing plate body 7.Certainly, do not influencing under the prerequisite of solar module with the pressing plate works better of single crystal growing furnace that present embodiment provides, the degree of depth of groove can not done concrete qualification.
Concrete, pressing plate body 7 is the graphite pressing plate, the first side wall 8 and second sidewall 9 are graphite side wall.Consider to reduce that pressing plate body 7, the first side wall 8 and second sidewall 9 still adopt graphite material of the prior art, to obtain maximum productivity effect to the change of existing installation and the job requirement of satisfying single crystal growing furnace production as far as possible.
Based on the pressing plate of the solar module that provides in the foregoing description with single crystal growing furnace; The utility model embodiment also provides a kind of solar module to use single crystal growing furnace, and this solar module has the solar module that provides in the foregoing description pressing plate with single crystal growing furnace with single crystal growing furnace.
Because this solar module has adopted solar module that the foregoing description the provides pressing plate with single crystal growing furnace with single crystal growing furnace; So the beneficial effect that this solar module is brought with the pressing plate of single crystal growing furnace by solar module with single crystal growing furnace please refer to corresponding part in the foregoing description, repeats no more at this.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
