Silicon wafer is dried by heating and hot air circulation, gas source is mainly workshop air, subsequently into next process.By
It is mainly workshop air in the gas source of traditional drying mode, or by the gas of high efficiency filter, therefore clean level is not
It is enough, monocrystalline efficiency, yield are affected greatly.
Utility model content
Technical problem to be solved by the utility model is: a kind of solar battery sheet drying unit is provided, it can be preferable
Improve the efficiency and yield of monocrystalline.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of solar battery sheet drying unit,
Including board；Drying tank is provided on the board；Internal circulation drying pipe is provided on the inner wall of the drying tank；Institute
Internal circulating air outlet is offered on the inside circulation drying pipe stated；The lower end of the board is provided with outer loop gas
Entrance and drying tank heating tube；One end of the drying tank heating tube connects outer loop gas access；In other end connection
Portion's circulation drying pipe；The lower end of the board is additionally provided with high purity inert gas entrance；The high purity inert gas entrance
It is connected to drying tank inner cavity.
Further, in order to dry silicon wafer uniformly, internal circulation drying pipe described in the utility model is uniformly distributed
On the inner wall of drying tank.
Further say, in order to keep the intake of inert gas controllable, high purity inert gas described in the utility model
Entrance is provided with valve；The valve opening is 0~100%.
It further says, for the ease of maintenance, board lower end described in the utility model is additionally provided with maintenance window；Machine
The bottom of platform is provided with liquid discharge outlet.
Further say, in order to improve efficiency, drying heating tube described in the utility model, outer loop gas access
It is at least one with high purity inert gas entrance.
The utility model has the beneficial effects that solve defect present in background technique, compared with traditional drying unit,
Increase gas path pipe all the way on traditional infrastructure, high purity inert gas can be passed through, drying interior zone cleaning is improved, so that silicon wafer
Clean surface degree greatly improves, final to improve single crystal battery piece transfer efficiency and yield.
