specific Embodiment 2

[0076] The specific embodiment 2 of the flow channel turning device of the present invention, the difference between the flow channel device described in this embodiment and the above specific embodiment 1 is only that: as Figure 14 Shown, c=2b=λ 2 / 2, the cross-section of the closed spiral fluid channel 1150 surrounded by adjacent curved plates 10 is close to a circle, which can improve the flow capacity and reduce the channel resistance.

[0077] The specific embodiment 3 of the flow channel turning device of the present invention, the difference between the flow channel device described in this embodiment and the above specific embodiment 1 is only that: as Figure 15 As shown, the section of the helical groove 111 is V-shaped, and the section of the enclosed helical fluid channel 1151 is quadrilateral, as shown in Figure 15 As shown, the function curve of the endpoint trajectory of the datum line of the spiral groove 111 is a triangular wavy line with a right angle, and...

specific Embodiment 5

[0080] The specific embodiment 5 of the flow channel turning device of the present invention, the difference between the flow channel device described in this embodiment and the above specific embodiment 5 is only that: Figure 18 As shown, at least two curved panels stacked together in the flow channel bending device form a curved panel module, and the adjacent curved panels 1 in the curved panel module are arranged alternately 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 flow disturbance effect.

specific Embodiment 6

[0081] The specific embodiment 6 of the flow channel turning device of the present invention, the difference between the flow channel device described in this embodiment and the above-mentioned specific embodiment 1 is that the flow channel turning device of the present invention is used in 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 , to achieve heat exchange. The heat exchange plate of the rotary air preheater of the present invention is a curved plate, and the specific structure of the curved plate is the same as that of the curved plate described in Embodiment 1. The curved plate is used as the heat exchange plate to form a large number of spiral fluid channels in the rotor of the air heat exchanger, and the spir...

Abstract

The invention relates to the field of fluid interaction devices, in particular to a curved-surface plate and a flow channel bending device using the curved-surface plate. The curved-surface plate is provided with a spiral groove, the spiral groove is provided with a datum line, the datum line is cylindrical spiral line, and the wall face of the spiral groove is a curved surface for passing after the datum line performs translation according to a set trajectory. Compared with the flow channel bending device which can only make a fluid disturbed in one plane. When the curved-surface plate is used and the fluid passes through the spiral groove, a rotational flow can be formed in a space, the disturbing capability of the fluid can be enhanced, and meanwhile the length of a flow channel can be prolonged. The problem that an existing flow channel bending device has small fluid disturbance and accordingly low heat exchange efficiency, poor mixing effect and the like are caused is solved.

Description

technical field [0001] The invention relates to the field of fluid interaction equipment, in particular to a curved plate and a flow channel bending device using the curved plate. Background technique [0002] According to the principle of fluid flow, when fluid flows in a straight channel, the flow velocity of the intermediate fluid is greater than that of the fluid close to the wall of the channel. Such as figure 1 As shown, when the common channel bending device is applied in the field of heat exchange, the fluid close to the channel wall 100 flows slowly, resulting in a small temperature difference between the fluid in the channel 101 and the fluid outside the channel, and low heat exchange efficiency; When it is applied to the high-dust heat exchange field, it is easy to cause dust to accumulate on the flow channel wall, resulting in blockage of the heat exchange channel; when it is applied to the mixing field, the mixing effect is poor. [0003] The curved plate stru...
