Enterprise is to sustainable development, it is necessary to which possessing new technology and product quality improves, and existing photovoltaic enterprise is in cell piece skill
It is opposite in art to reach balance, workshop section is spread as cell piece core workshop section, is required on sheet resistance control point relatively strictly, at present
There are also many shortcomings in uniformity and exhaust emissions problem in piece, for example, diffusion air inlet at this stage is mainly by blowing
Fire door bottom rebound mode be diffused, due to fire door apart from furnace tail farther out, spacing is small between piece, stop gas flow rates,
Cause diffusion when furnace cauda in uniformity it is poor compared with fire door, in addition, at present exhaust emissions be also cause piece it is undesirable one of them
Factor, current device exhaust pipe are only arranged an exhaust pipe, are closely located to boiler tube bottom, when all gas is arranged simultaneously in pipe
When putting, it is easy to cause boiler tube top gas that cannot effectively discharge, generates the phenomenon that metaphosphoric acid is assembled, reduces solar battery sheet
Sheet resistance uniformity and electrical performance of cell parametric stability.
Summary of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, a kind of diffusion uniformity of solar battery that improves is provided
Flow-harmonization device.
The present invention solves technical solution used by above-mentioned the deficiencies in the prior art: a kind of flow-harmonization device, including boiler tube
Ontology, fire door and be set to the intrinsic admission line, last row pipeline and thermocouple assembly, which includes even flow plate
With uniform flow pipe, wherein even flow plate is fixed in the boiler tube ontology, positioned at the furnace bottom end of the boiler tube ontology, the plate body of the even flow plate
It is equipped with multiple first row stomatas irregularly arranged；Uniform flow pipe is mobilizable to be fixed in the boiler tube ontology, and the boiler tube is located at
The furnace roof end of ontology, the uniform flow pipe connect the admission line, and the tube wall of the uniform flow pipe is equipped at intervals with multiple second row stomatas.
Preferably, furnace tail end of the outlet of the gas vent towards the boiler tube ontology.The gas being passed through in furnace enters uniform flow pipe
Afterwards, it is blown by uniform flow pipe to silicon wafer surrounding, to promote silicon wafer sheet resistance uniformity, makes the steady of electrical property after its silk-screen printing
It is fixed.
Preferably, which further includes a detachable adapter, and one end of the detachable adapter connects the air inlet
Pipeline, the other end connect the uniform flow pipe.
Preferably, it is 1/2 times of top pore size set on the aperture of the second row stomata of the uniform flow bottom of the tube, is set to
The aperture of the second row stomata at left and right sides of the uniform flow pipe is 2 times of bottom part aperture diameter size, this aperture design can make gas
It evenly distributes at four edges of silicon wafer and spreads uniformly, uniformity in effective lifting tab.
Preferably, the pore size of the first row stomata is uniform, and exhaust gas in pipe can more effectively be made to discharge.
Compared to the prior art, flow-harmonization device of the invention is made of circular rings quartz ampoule, is fixed on boiler tube tube wall,
Air inlet pipe end is connect with uniform flow pipe by detachable adapter, gas by uniform flow pipe to silicon wafer surrounding jet, make gas with
Silicon wafer preferably spreads knot, and avoiding when gas is sprayed on fire door rebound diffusion by the prior art causes gas dispersion uneven,
So that four side of silicon wafer is different extremely to center diffusion velocity, the non-uniform drawback of the knot depth, to efficiently solve gas motion
The different problem of speed effectively improves silicon wafer sheet resistance uniformity.In addition, the present invention increases even flow plate in boiler tube tail portion, make in boiler tube
Exhaust gas more effectively discharges, and avoids last row in the prior art and is made of an exhaust pipe, when gas discharges simultaneously in boiler tube,
The drawbacks of gas cannot be discharged effectively after increasing even flow plate, when gas is entered between boiler tube tail portion and even flow plate, exists certain
Cushion space discharges gas uniform speed, reduces load in pipe.The present invention can be effectively improved sheet resistance uniformity in solar cell piece,
After cell piece sintering, good Ohmic contact is formed it into, the electric performance stablities such as short circuit current, fill factor can be improved,
Be conducive to component stability and anti-Decay Rate, to improve the service life of solar module.
