Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0015] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See also Figure 1 As shown, a linear heater involved in this embodiment includes a tube 1 with an axis extending horizontally to the left and right, and cover plates 2 are respectively provided at both ends of the tube 1. Two axial flow fans 3 are respectively provided in the tube 1, and the air inlet end of the axial flow fan 3 faces the cover plate 2, and the air outlet end faces the cover plate 2. An air inlet 4 is provided on the cover plate 2, and a partition 5 is provided between the two axial flow fans 3. A mounting hole 6 is provided on the partition 5, and a PTC heater 7 is embedded in the mounting hole 6. A cold air channel 8 located above the partition and a hot air channel 9 located below the partition are formed between the partition 5 and the tube 1, and baffles 10 are respectively provided at both ends of the hot air channel 9 to separate it from the cold air channel, and an air outlet 11 opened on the tube 1 is provided below the PTC heater 7.

[0018] Furthermore, the bobbin 1 is provided with a hanging hole 14 at the top.

[0019] Furthermore, the spoiler 10 is arranged at an angle.

[0020] In this embodiment, the axial flow fan 3 and the PTC heater 7 are powered on at the same time, the PTC heater 7 generates heat, and the axial flow fan 3 draws external air along the air inlet 4 to the cold air channel 8. After being heated by the PTC heater 7, the air enters the hot air channel 9 to form hot air, which is finally discharged from the air outlet 11.

[0021] The baffle plate 10 is added to block the cold air passage 8 and the hot air passage 9 which are originally connected to each other.

[0022] The hanging hole 14 is provided so that the linear heater can be hoisted as a whole.

[0023] Among them, by setting the spoiler 10 to be in an inclined state structure, the wind resistance is reduced, a certain wind guiding function is provided, and wind loss is avoided.
