Slot-die type gas distribution device for photovoltaic manufacturing

A slot-die type gas distribution device for photovoltaic manufacturing, comprising a first gas distribution device, wherein the first gas distribution device is provided with a first inlet and a first outlet;

• the first gas distribution device comprises a first gas distribution tube;
• the first inlet is arranged at a top of the first gas distribution tube, so that a flow direction of gas passing through the first inlet is perpendicular to a bottom surface of the first gas distribution tube, and the top of the first gas distribution tube is a highest position of the first gas distribution tube from the ground;
• the first inlet is arranged at a center of the top of the first gas distribution tube;
• wherein the first gas distribution tube is semicircular;
• and the first gas distribution tube includes a first rectangular plane and a first curved surface;
• the first rectangular plane is located beneath the first curved surface and is parallel to the ground;
• and
• the first inlet is arranged on the first curved surface, and a height of the first inlet from the first rectangular plane is a radius of the first gas distribution tube.
