• a conduit structure for molten glass, and at least one of a first cooling system or a second cooling system;
• wherein:
• the conduit structure axially penetrates through a throat in a throat brick to form a transmission channel for a glass fluid, the conduit structure including at least one conduit made of platinum or platinum alloy, wherein the at least one conduit made of platinum or platinum alloy has a bellows shape, and a structural form of the bellows shape includes at least one of a first bellows structure or a second bellows structure;
• the first cooling system is disposed on an inner wall of the throat and is not in direct contact with the conduit structure;
• and
• the second cooling system is arranged inside the throat brick.
