Description
Technical field
The utility model belongs to a kind of molding device that ultra-white photovoltaic glass uses of producing, specifically a kind of rolling press that photovoltaic glass uses and stack refrigerating unit of rolling press produced.
Background technology
Sun power is a kind of renewable energy source of cleanliness without any pollution.The advantage of solar energy photovoltaic glass is to utilize solar energy to be not to the utmost in a steady stream converted to controllable electric energy.It has does not discharge to human body and the harmful gas of environment, without Greenhouse effect, noiselessness, the advantage such as reliable, the life-span is long.
At present, the molding device of ultra-white photovoltaic glass is a kind of rolling press with upper and lower two stacks.Hot glass metal extrudes the glass of different thickness by the roller of upper and lower two rotations.In glass normal productive process, stack is not stop rotation, and upper and lower two stacks are subject to the heat transmission of glass metal (temperature is about 1100 DEG C) conduction and radiation, the surface temperature of stack is also about 700 DEG C of left and right, for this reason, bending for preventing that stack from producing, must carry out cooling to stack inside. the cooling of stack realized by the inner water flowing of stack.
