Embodiment 1
[0061] Embodiment 1, reference figure 1 , figure 2 , image 3 , an aerodynamic friction heat generation high-temperature hot air blower, including a casing 1, a casing air inlet 2, a casing air outlet 3, an impeller 4, an impeller blade disc 5, an impeller blade 6, an impeller middle air inlet 7, and an inner flow channel of the impeller 8. The inner flow channel 9 of the casing, the impeller is composed of three layers of impeller blade discs 5, two layers of impeller blades 6 and two layers of impeller inner flow channels 8 superimposed in the axial direction, and the axial distance between the inner flow channels of each layer of impeller is relatively large , there are four impeller blades in the inner flow channel of each impeller, and dozens of longitudinal (radial) circuitous and bent frictional heat induction plates are arranged. The structural shape and size of each circuitous and curved frictional heat induction plate are the same , each frictional heat-generating...
Embodiment 2
[0065] Embodiment 2, refer to Figure 4 , Figure 5 , Figure 6 , this example is basically the same as Example 1, the difference is that in this example the impeller inner channel 8 is a three-layer superimposed structure, the entire impeller is provided with four layers of impeller blades, the inner channel of the impeller is one layer on the axial front side, and the axial One layer towards the rear and one layer in the middle of the axial direction. The inner flow channel of each impeller layer is composed of six arc-shaped blades 6 and impeller discs 5 on both sides. There are two arc-shaped impeller blades in the inner flow channel of each impeller layer. There are horizontal (circumferential) meandering frictional heat-generating induction fins between them. The frictional heat-generating induction fins in the inner flow channel of each layer of impeller are very narrow, and the inner flow channel of each layer of impeller and the heat-generating airflow channel are V...
Embodiment 3
[0069] Embodiment 3, refer to Figure 7 , Figure 8 , this example is basically the same as Example 2, the difference is that the inner channel of the impeller in this example is a four-layer superimposed structure. The second difference is that the surface of the impeller disc in this example is made of uneven iron plates, and each layer There are 6 arc-shaped blades in the inner flow channel of the impeller, and 3 longitudinal (radial) circuitous and bent frictional heat-generating induction plates are arranged between every two arc-shaped blades.
[0070] The third difference is that in this example, there are several meandering and bending frictional heat generating induction sheets 10 inside the flow channel 9 inside the casing, and the frictional heat generating induction sheets 10 are connected with the casing side wall.
[0071] When this example is working, because of the double function of the circuitous and curved frictional heat generation induction sheet in the i...
