Fig. 2 is the longitudinal section view of a kind of air heating apparatus that the present invention proposes.
Detailed description of the invention
Below, by specific embodiment, technical scheme is described in detail.
As shown in Figure 1-2, Fig. 1 is the structural representation of a kind of air heating apparatus that the present invention proposes；Fig. 2 is the present invention
The longitudinal section view of a kind of air heating apparatus proposed.
Reference Fig. 1-2, a kind of air heating apparatus that the embodiment of the present invention proposes, including: heater strip 1, glass tubing 2 and wing
Sheet 3, described heater strip 1 is encapsulated in glass tubing 2, and first envelope being respectively arranged at two ends with for encapsulating heater strip 1 of glass tubing 2
5 and second end socket 6, first end socket the 5, second end socket 6 all uses ceramic material to form, first end socket the 5, second end socket 6
Fixing glue it is filled with respectively with glass tubing 2 junction；One end of described heater strip 1 connects leaded 4, and lead-in wire 4 is positioned at glass
The outside of pipe 2, lead-in wire 4 has U-shaped lug plate 8 away from one end connection of glass tubing 2；Described fin 3 is banding, and fin 3 is at glass
Fix along glass tubing 2 length direction coiled coil and with glass tubing 2 on the outer peripheral face of pipe 2, and fin 3 is at spiral winding glass tubing 2
Fold is formed during coiled coil；Described fold groove extends along the radial direction of glass tubing 2, and the groove width of fold groove is by near glass
The one of pipe 2 is laterally away from the side of glass tubing 2 and is progressively incremented by, and the degree of depth of fold groove is laterally away from glass by near the one of glass tubing 2
