In the prior art, a method of wrapping and sealing the heating wire in a high-temperature-resistant alloy shell is adopted, so that air is isolated, and the effect of preventing the heating wire from being oxidized can be achieved. However, the heat exchange efficiency and the dynamic response performance are still affected due to the fact that the heat radiation heat exchange mode is mainly used between the heating wire and the inner wall of the heating channel around the heating wire, and the problem cannot be solved fundamentally.
