Example Embodiment
[0076] Specific embodiment 2 of the runner turning device of the present invention. The runner device described in this embodiment differs from that in the above specific embodiment 1 only in: Figure 14 As shown, c=2b=λ 2 / 2, the cross section of the closed spiral fluid channel 1150 enclosed by the adjacent curved panels 10 is close to a circle, which can improve the flow capacity and reduce the channel resistance.
[0077] Specific embodiment 3 of the runner turning device of the present invention, the runner device described in this embodiment differs from the above specific embodiment 1 only in: Figure 15 As shown, the cross section of the spiral groove 111 is V-shaped, and the cross section of the enclosed spiral fluid channel 1151 is quadrilateral, such as Figure 15 As shown, the function curve of the end-point trajectory of the reference line of the spiral groove 111 is a triangular wavy line with a right angle, and a plurality of independent spiral fluid channels with a sq...
Example Embodiment
[0080] Specific embodiment 5 of the runner turning device of the present invention, the runner device described in this embodiment differs from the above specific embodiment 5 only in: Figure 18 As shown, at least two curved panels stacked together in the runner bending device constitute a curved panel module, and adjacent curved panels 1 in the curved panel module are alternately arranged in length in the length direction of the spiral groove, The directions of the fluid outlets of adjacent curved panel modules intersect, and the fluids can disturb each other outside the outlets to produce a turbulence effect.
Example Embodiment
[0081] Specific embodiment 6 of the flow channel turning device of the present invention. The flow channel device described in this embodiment is different from the above-mentioned specific embodiment 1 only in that the flow channel turning device of the present invention is used for a rotary air preheater, Such as Figure 19 As shown, the rotary air heat exchanger 8 includes a heat exchange plate 81. The heat exchange plate 81 passes between the cold medium and the heat medium during rotation. The heat exchange plate absorbs heat in the heat medium and releases heat in the cold medium. , Realize heat exchange. The heat exchange plate of the rotary air preheater of the present invention is a curved panel, and the specific structure of the curved panel is the same as the structure of the curved panel described in specific embodiment 1. The curved plate is used as a heat exchange plate, and a large number of spiral fluid channels are formed in the air heat exchanger rotor, and th...
