Specific embodiment
The present invention describes a kind of fan/turbine/pump 1, which has the leaf of substantially spiral forming
Piece, the blade have the fluid inlet axially aligned with longitudinal axis.Blade in fluid inlet portion has flat and/or recessed
The pressure face of shape.The root of one or more blades in fluid inlet portion is opposite according to logarithm, index, power or other sequences
It is substantially helically shaped in longitudinal axis, so that the tangent line of blade hangs down in the first end of fluid inlet portion close to axis
Straight alignment, and the second end of fluid inlet portion close to axis parallel alignment.Fluid outlet and fluid inlet are longitudinally
Offset.
In yet another embodiment of the present invention, the part of the second substantially spiral forming has and the first substantially spiral shell
Revolve the opposite chirality in the part of forming, wherein the tangent line of blade is at the center of fluid inlet portion close to perpendicular to the axis
Alignment, and the both ends of fluid inlet portion close to the equal parallel alignment of axis.
Fig. 1 is the example for opposite-handed fan/turbine/pump 1 shell, and the fan/turbine/pump 1 drives fluid
The opening 10a and 10b of the end of shell 7 are flowed to from all sides of housing parts 2.Air is along the spiral shell in housing parts 2
Vane piece 6a and 6b is deflected towards Outer housing component 3a and 3b, and at Outer housing component 3a and 3b, fluid is distributed to opening simultaneously
Except 10a and 10b.Opening 4 in housing parts 2 can have any size or shape along any side.Longitudinal boundary 8a
The part 5 of air sucking is defined with 8b.In the application of fan, diffuser 14 there may come a time when it is desired.The example of application
It can be the vertical fan driven by motor 9, or the turbine by Wind-driven rotating helical blade 6a and 6b.
There is provided opening 10a and 10b in the end of shell 7 may be useful in many other applications, such as in pipe
Have at the T-junction in road fluid is transported to two pipelines from a main pipeline branch, or as hydroelectric generator or
Wind-driven generator.Under some cases for needing cross flow one, the opening in housing parts 3a and 3b can be in side, Huo Zhe
Discussed further below can also fully open in some cases.Application range can be very wide, is not limited to any fluid.
Fig. 2 is an exemplary top view of heat recovery units shell.Heat recovery system usually passes through heat transfer unit future
Flow of fresh air is transmitted to from the heating and cooling of internal air stream.Heat recovery system at least needs two fans, and one is used to
Fresh air is pumped, another is used to pump stale air.This example illustrate the opposite helical fan/whirlpools of two chiralitys
How wheel/pump 1 passes through while to two heat transfer case 12a and 12b (rather than only one heat transfer case) supplied fresh air or not
Fresh air increases output and efficiency.
Along the side of shell 7a there is the fan of opening for example can suck air from outside, and along the side of 7b
Fan with opening can suck air from inside.In some cases, all sides of first part can open.With
Afterwards, the stale air in the fresh air and 7b in shell 7a can be driven towards heat transfer unit 12a and 12b.Then, quilt
The fresh air that stale air is heated or cooled is introduced internal by opening 13a and 13b, while stale air is from opening
11a and 11b discharge.Heat transfer unit can be arranged differently or can be it is elongated, enable to carry out counter-flow arrangement, should
Counter-flow arrangement is arranged more efficient than cross flow one.Therefore, opposite-handed fan/turbine/pump 1 enables the system of spaces compact
A greater amount of fluids enough is supplied using only two fans, to serve two heat transfer units, in some cases, as described below
Simpler half fan/turbine/pump 1 can be it is beneficial.
In order to increase the volume efficiency of inlet stream, the root of helical blade 6 is according to logarithmic progression (such as fibonacci number
Column) approximation along axis draw.In fact, the position of the root of blade 6 can approximate any logarithm, index, power or other
The linear extrapolation of ordered series of numbers or these ordered series of numbers, to realize target described herein.It visually sees, this makes blade first
Almost vertical alignment, subsequent helical blade 6 are gradually stretched along axis with axis, until it is tangentially close to parallel with axis right
Together.
It is the example of such a ordered series of numbers below, as follows, every number in fibonacci series is all the first two number
Sum.One column of the right is the example of the scaled fibonacci series of 125mm long axis.This indicate along axis away from
The distance of origin.
Fig. 3 is a schematic example, is illustrated how an opening of the side in axis of fan/pump/turbine 1
Applied to another opening longitudinally deviated with the first opening.Cross-sectional axis 15 is segmented into equal sector, such as 25.7
Spend the sector of (deg).Ordered series of numbers 16 can be distance of the angle turning point away from origin 23 at each 25.7 degree.These points are along axis
The spacing of line continues to broaden, until having carried out 7 25.7 degree of steerings around axis 15, the root surface pair of helical blade and its
The opposite direction of the initial position of origin 23, and along axis and about 50 millimeters of origin interval.However, make blade close to
It is not necessarily required to the position of axis parallel alignment in face of the direction opposite with its initial position.In this illustration, which connects
It is bordering on the transition from fluid inlet to fluid discharge outlet, the reason is that the tangent line of helical blade is arranged essentially parallel to axis now, and
And its ability for sucking fluid substantially reduces.In fact, opening, which is extended beyond this point, to generate negative resistance with fluid flow
Power simultaneously generates reaction.A part (such as part between 50mm and 75mm) of fan is completely enclosed be it is beneficial, to keep away
Exempt from this negative resistance power and forms pressure.
In short, helical blade 6 (or being 6a or 6b in the case where opposite-handed fan/pump/turbine 1) is initially basic
On tangentially perpendicular to the axis of inlet, the position sources of root are from ordered series of numbers as described above, so that resistance minimally cuts fluid
And maximize fluid inlet.Other than along the further fluid inlet of axis, second purpose be tangential variations rate gradually
Slow down, smoothly to shift the fluid along axis.When the tangent line of blade is close to axis parallel alignment, function is then
Continue along axis transfering fluid, the forward position blade-shaped of the fluid is being discharged into pressure sometimes.
By increasing axis on the direction of the first end of first end part (any position until and including blade tip)
Linear diameter, fluid stream can be smoothly guided further along the axis at first end part.Equally, if it is desired to towards axis
The other end to external drainage, for example, axis diameter can towards the second end part second end (any position until and including
Blade tip) increase again.The change rate of axis diameter can also follow logarithm or other ordered series of numbers, so that it is also in first part
First end or second part second end close to alignment perpendicular to the axis, and in the second end and second part of first part
First end close to axis parallel alignment.
The reverse adaptation of the logarithmic series of root of blade can be at Outer housing component 3 in blade 16 or 16a and 16b
Accelerate the discharge of fluid in rotary course.But the other methods for helping that fluid is discharged can be used, these methods include example
Such as it is transitioned into substantially conical helical blade 16 or 16a and 16b, one or more sawtooth 17 along edge, increase blade
Quantity, change into male blade, another fan/turbine 26 and purpose positioned at axis end as shown in Figure 4 is that have
Effect ground deflecting liquid and any other method that fluid is discharged to the outlet longitudinally deviated with entrance.
The position of Fig. 4 and Fig. 5 split shed 4 depends on cutting for the tangential angle of blade 6 in Fig. 5 or blade 6a and 6b in Fig. 4
Line angle degree.In the case of figure 4, these blades opening 4 centre origin 23 at close to 21 vertical alignment of axis, and
In the case of fig. 5, these blades at outer limit 8a close to 21 vertical alignment of axis.Air is along the spiral in Fig. 4
