Abstract
The utility model relates to the technical field of solar batteries, particularly to a device for cooling a sintering furnace of solar batteries. The device comprises a furnace body; a water cooling zone and an air cooling zone are sequentially arranged in the furnace body; circulating cooling water is communicated to the water cooling zone, and nitrogen is communicated to the air cooling zone; two sets of metal pipes are mounted above and below a transmission chain in the air cooling zone, respectively; and circulating cooling water is also communicated into the metal pipes. Cooling water is communicated to the air cooling zone, so that the cooling effect is reduced, the out-of-table temperature of the battery sheets is reduced from 70 DEG C to 30 DEG C, such parameters as series resistance of the battery sheets, filing factors and battery efficiency are improved, and the production process of the battery sheets is further optimized.
Description
Technical field
The utility model relates to technical field of solar batteries, relates in particular to a kind of solar cell sintered furnace cooling device.
Background technology
In the existing solar battery sheet production procedure, sintering process is a vital link, the quality of sintering directly has influence on the electricity conversion of battery, the fill factor, curve factor of the battery of high-quality sintering process can reach 78%, transformation efficiency can surpass 17%, but sintering quality is bad, and battery efficiency descends 3 percentage points at least.Because existing agglomerating plant adopts Despatch sintering board mostly, solar cell Despatch sintering board is behind the high temperature sintering zone, only there is the water-cooled district of one section 100cm to come cooling down high-temperature battery sheet, actual test still has 70 degree through the battery sheet surface temperature of this cooling effect, there is not efficient cooling, to the series resistance of solar battery sheet, fill factor, curve factor and these parameters of battery sheet efficient affect.
The utility model content
The technical problems to be solved in the utility model is: can not give the silicon chip efficient cooling in order to overcome existing agglomerating plant cooling zone, and then, provide a kind of solar cell sintered furnace cooling device to problem such as affect such as efficient of fill factor, curve factor and battery sheet.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of solar cell sintered furnace cooling device, has body of heater, be provided with water-cooled district and air-cooled district in the body of heater successively, logical recirculated cooling water in the water-cooled district, logical nitrogen in the air-cooled district, the conveyer chain in air-cooled district is installed two groups of metal tubes up and down, the cooling water of logical circulation in the metal tube.
The beneficial effects of the utility model are: increase water cooling in air-cooled district, further reduced cooling effect, the appearance temperature of battery sheet can drop to 30 degree by 70 degree, thereby parameters such as battery sheet series resistance, fill factor, curve factor and battery efficiency all are improved, have also further optimized the production procedure of battery sheet.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1. body of heater, 2. water-cooled district, 3. air-cooled district, 4. metal tube.
The specific embodiment
As shown in Figure 1, a kind of solar cell sintered furnace cooling device, has body of heater 1, be provided with water-cooled district 2 and air-cooled district 3 in the body of heater 1 successively, logical recirculated cooling water in the water-cooled district 2, logical nitrogen in the air-cooled district 3, the conveyer chain in air-cooled district 3 is installed two groups of metal tubes 4 up and down, the cooling water of logical circulation in the metal tube 4, conveyer chain are driven and then are carried the battery sheet by the conveyer chain driving mechanism and carry out water-cooled and air-cooled.
Solar battery sheet is after the sintering zone sintering, enter the water-cooled district and lower the temperature, then enter again in the air-cooled district under the common cooling effect of air-cooled and water-cooled, strengthen the cooling effect of battery sheet, make the appearance temperature of battery sheet drop to 30 degree, so that guarantee the test of follow-up battery performance by 70 degree.
