Glass manufacturing apparatus with cooling devices and method of using the same

Glass manufacturing apparatuses with cooling devices and methods for using the same are disclosed. In one embodiment, an apparatus for forming a glass web from molten glass includes an enclosure and pulling rolls that cooperate to draw a glass web in a draw direction rotatably positioned in an interior of the enclosure. A cooling device for extracting heat from the glass web is in fluid communication with a cooling fluid source and includes an actively cooled flapper disposed in the interior of the enclosure that is movable to facilitate varying the heat extraction. The actively cooled flapperserves as a heat sink in the interior of the enclosure and the cooling fluid extracts heat from the actively cooled flapper to remove heat from the glass web and the enclosure. 公开了具有冷却装置的玻璃制造设备及其使用方法。在个实施方式中，用于由熔融玻璃形成玻璃网的设备，包含外壳与可旋转地置于外壳内的牵引辊，所述牵引辊协作以在拉制方向拉制玻璃网。用于从玻璃网提取热的冷却装置与冷却流体源流体连通，并包含布置在外壳内的主动冷却式档板，该主动冷却式档板可移动以便于改变热提取。主动冷却式档板作为外壳内的散热器，且冷却流体从主动冷却式档板提取热，以从玻璃网与外壳移除热。
