- the thickness of the filter body 110 becomes too small, so that the circumferential length (circumference) of the inner virtual line 132 and the circumference of the outer virtual line 122 ( Since there is no significant difference in the circumference), the differential pressure loss due to the inner bent portion 131 or the interference phenomenon of the inner bent portion 131 is not large, and accordingly, the effect of causing the recessed unit wave shape 133 to be repeated is halved. .
- the thickness of the filter body 110 and the area of the filter material corresponding thereto become too large, so that the overall pressure loss increases significantly, and the circumferential length of the inner virtual line 132 (circumference ) Becomes too small compared to the circumference (circumference) of the outer virtual line 122. Accordingly, when forming a tube shape after applying the adhesive member 160 to the filter media 111, there is a problem of bursting or tearing the joint around the inner virtual line 132, so that the bending type filter member 100 It becomes difficult to manufacture.
- the thickness of the filter body 110 at a portion where the distance between the inner virtual line 132 and the outer virtual line 122 is the minimum When referring to the second thickness T2, it is preferable that the second thickness T2 has a range of [Equation 2] with respect to the first thickness T1.
- the width of the bent portion corresponding to the second thickness becomes too small, so that the bending process is out of range.
- the second thickness T2 is greater than T1/1.2, the difference from the conventional filter structure formed by winding the filter media 111 bent in multiple stages with the same width is not large, so the differential pressure due to the inner bent portion 131 The effect of improving the loss or improving the interference phenomenon of the inner bent portion 131 is negligible.
- the number NW of the unit wave shapes 133 formed by the inner virtual line 132 has a range of [Equation 3] with respect to the diameter D of the outer virtual line 122.
- the number (NW) of the unit wave forms 133 formed by the inner imaginary line 132 is smaller than D/33, the difference in shape compared to the conventional case in which the inner imaginary line 132 forms a circular shape. Since is not large, the effect of improving the differential pressure or improving the interference due to the introduction of the unit wave form 133 is extremely small.
- the number NW of the unit wave shapes 133 formed by the inner virtual line 132 is larger than D/7, the number of unit waves becomes too large, making bending and the entire manufacturing process difficult.
- the number of inner bent portions 131 forming the unit wave shape 133 decreases.
- the gap between the inner portion of the filter body 110 becomes larger than necessary, so that the amount of the filter media 111 extending to the inner portion decreases, making it difficult to sufficiently secure filtration performance.
- the spacing P (a linear distance between edges as shown in FIG. 2) may have a value between 3 mm and 5 mm.
- the gap (P) is less than 3mm, it is difficult to secure a space through which air can be easily introduced into the valley formed by the inner bent part 131, and if the gap (P) is larger than 5mm, it is not possible to sufficiently secure the area of the filter media. Therefore, there is a limit to the efficient implementation of filtration performance.
- the tube-shaped bent filter member 100 includes the diameter (D) of the filter body 110, the thickness of the portion forming the bent portion (T1, T2), and the unit wave form ( By optimizing and setting at least some of the number (NW) of the number of 133) and the gap (P) between the corners of the inner bent portion 131, it is possible to improve the differential pressure and optimize the use of the filter media area, and also the filter media 111 is bent. It is possible to improve workability such as bending processing and winding processing in which the bent filter media 111 is wound in a tube shape, so that the manufacture of the filter body 110 is facilitated.
