The present invention relates to for filtering or the filter of the particle of separation different size.The most common use of filter be
In motor vehicle and truck.Filter is to remove solia particle from the air that internal combustion engine uses.Filter in addition to
Particle is removed from oil used in engine and speed changer.
Typically, filter used in these applications is micro- to remove from air or oil using the diaphragm with aperture
Grain.Usually material is repeatedly folded to form filtering material surface area as big as possible on the small gross area.
In addition these small apertures of particle of small size aperture capture small size in diaphragm are generated for extending there through
More limitations of the flowing of the fluid or gas of filter.In the case where the air filter for internal combustion engine, small aperture can
To lead to reduced performance and reduced fuel economy.If aperture is larger, performance is improved, but engine life reduces.
Filtering configuration also can be used to separate different size of particle from fluid.The separation of particle can be used for from fluid
Separate biomaterial or different size of molecule.
The desalination (desalination) of water is a wherein field by filtering material to separate different size molecule.
This mission requirements removes chlorination sodium molecule from small hydrone.About the desalination of seawater, sodium chloride is to the opposite of hydrone
Amount is higher.Due to this height ratio, when handling the water of some moderate amount, the sodium chloride of higher amount is collected in the filter.
According to some embodiments, this technology is related to a kind of filter, and the filter is with more in conjunction with structural elements
Deck panels or film, these components are laminated together to form series of channel, to filter or trap the micro- of prescribed level
Grain or molecule.These panels have the entrance region formed by wider passages, only constrain big particle here.These entrance regions
Panel during manufacture is promoted to crack.It is a series of tapered channels after entrance region, to limit passing through for particle.Filtering
Interconnection between channel allows the cross matrix stream of the adjacency channel from different in width.
In the background technology, typically, a full line structure is by the channel including only one width.For being typically used in oil
Branch type filter in filtering, a line can have the channel of different in width.For example, in a kind of the micro- of the prescribed level to be filtered
Grain or molecule occupy in the situation of significant percentage, and a series of branch rows will be present to collect the micro- of larger amount of prescribed level
Grain or molecule.
In addition, the filtration channel of rectangular cross section allows the more effective collection for substantial circular particle or molecule.For
Reduce flowing limitation, can leading edge to channel and rear add rounding.
The example of the filter 1 according to this technology construction is instantiated referring initially to Fig. 1, Fig. 1.Fluid or gas are from filtering
The top surface 2 of device 1 or " import " are flowed into filter 1.Filter panel 3 is stacked together, wherein filter panel 3
The top surface 2 of the formation of top edge 4 filter 1.The number of filter panel 3 stacked together will change according to design requirement
Become, such as those of ordinary skill in the art it will be clear that.In some embodiments, the number of filter panel 3 can be hundreds of
Or it is thousands of.The width of filter panel 3 can also change according to design requirement or specification, including but not limited to filter
Application (for example, desalination air filtration) to (versus) vehicle cabin.
Each panel 3 includes filtering front surface 1A and flat back surface 1B (referring to Figure 18).Panel 3 is also comprised along face
A pair of flanges 1C and 1D of the outer ledge arrangement of plate 3.These flanges are used to provide structural support to panel 3.In addition, when stacking
When panel, these panels will be at least combined together at their flange.
Exemplary filter (substrate) panel 3 includes vertically extending prominent of the first row arranged close to the top surface 2 of panel 3
Play portion 4A, and close to the vertically extending protrusion 4B of the second row that arranges of bottom surface of panel 3.The first row is vertically extending to dash forward
The portion of rising is preferably separated from each other out, to form vertical passageway 5A.Equally, the vertically extending protrusion of the second row preferably divides each other
It leaves, to form vertical passageway 5B.
It will be understood that vertically extending protrusion may include the rectangular teeth for example relative to the orthogonal extension in surface of panel 3
Shape object or block objects.These protrusions can have consistent shape and size relative to each other, or can be in shape (example
Such as, square, triangle, rectangle) and the aspect of size (for example, height, width, length) two it is irregular.
Vertical passageway 5A and 5B in filter panel 3 is vertically long along the level of the top edge 4 of filter panel 3
Degree arrangement.The number of vertical passageway 5A and 5B can change according to design specification.In some embodiments, panel 3 can wrap
Include hundreds of or thousands of vertical passageway 5A and 5B.In some embodiments, whole channels of filter 1 will be arranged together or
Person is configured to define consistent pattern, to form the filter 1 with uniform cross sections region.Even so, for filtering
The filter panel of the different application of device, different patterns can be stacked together by variation or irregular pattern.
In some embodiments, filter panel 3 includes the filtering protrusion 5C of one or more rows.For example, Fig. 1
Panel includes that six rows filter protrusion.About the additional detail of vertically extending protrusion and each row filtering protrusion relative to figure
2 are described in more detail.
With reference to Fig. 2, only one filter panel 3 is shown.Vertical passageway 5A and 5B are substantially equidistant relative to each other, and
And size is substantially the same.The width of each top vertical passageway 5A is desirably larger than the most of particles dispersed in a fluid.Example
Such as, vertical passageway 5A can be 200 microns wide and 200 microns of depths.The horizontal interval of vertical passageway 5A in filter panel 3 can
To be 300 microns, and the whole thickness of filter panel 3 can be 300 microns.
It will be understood that depth of the thickness closer to channel, then the global density of filter 1 is bigger.For example, vertical passageway 5A
Height can be 500 microns.This biggish size allows the variation in the manufacturing process of filter panel 3.It is bigger easy
Manufacturing, vertical passageway 5 can be higher than 500 microns.In other embodiments, if it is desired to more compact filter, then vertically
The height in channel 5 can be shorter than 500 microns.
Vertical passageway 5A is terminated in the first cross aisle 6.In one embodiment, the first cross aisle 6 leads to from vertical
The remote right side of vertical passageway 5A is extended on the left of road 5A.The height of first cross aisle 6 can be 200 microns, and will be excellent
Selection of land is identical as the depth of vertical passageway 5A.
With reference to Fig. 3, the front view of filter panel 3 is shown, fluid stream is depicted with arrow.The stream leaves perpendicular
To channel 5A, the first cross aisle 6 is flowed into.
Then fluid encounters the first row in multirow filtering protrusion.For example, the first row filtering protrusion 7A may include
Filtering protrusion separated from each other to form filtration channel 7B.Each filtration channel is sized to receive and keeps regulation ruler
Very little object, the particle being such as dispersed in the fluid for flowing through panel 3.
Panel 3 includes the filtering protrusion of six rows, these filtering protrusions form filtration channel.The filtration channel of given row
With roughly the same size.In addition, the size of filtration channel reduces relative to the position of the row.For example, closest to vertical
The width of the filtration channel of the row of channel 5A is greater than the institute closest to the vertical passageway 5B close to the outlet of filter panel 3
State the width of capable filtration channel.The width of the filtration channel of row therebetween continuously becomes smaller.
Panel 3 is " multi-stag " as a result, because it includes the filtering protrusion more than a line, these filtering protrusions
Capture disperses particle in a fluid to arrangement as follows, i.e., so that big particle is trapped in the filtering protrusion of top row
