Devices and methods for preventing a cooling flat tube of a platinum channel from collapsing during warming

A method for preventing a cooling flat tube of a platinum channel from collapsing during warming, implemented by a device including a traction structure, wherein

• a cooling flat tube is externally wrapped with a plurality of heater modules,
• there is a gap between the cooling flat tube and the plurality of heater modules,
• a docking seam is disposed between every two docked heater modules,
• the traction structure is disposed on an outer surface of the cooling flat tube,
• the traction structure includes a traction hanging bar, a position of the traction hanging bar coincides with a position of the docking seam, a protruding end of the traction hanging bar extends out of the docking seam,
• the protruding end is connected to an end of one of the two docked heater modules, and a height of the traction hanging bar is equal to a height of the gap between the cooling flat tube and the plurality of heater modules;
• and
• the method comprises:
• assembling the plurality of heater modules;
• filling the cooling flat tube with powder, wherein in the filling process, the cooling flat tube is vibrated, and the vibration of the cooling flat tube is stopped when the filling is finished;
• starting to heat the platinum channel;
• and
• after the platinum channel warms up to a preset temperature, performing a secondary filling on the docking seam where the traction hanging bar protrudes.
