2. Description of the Related Art A flat-shaped hollow strip and a free-falling or free fall composed of a liquid-absorbent fibrous material sandwiched between one flat wall and the other flat wall of the strip. A flat pipe tape having a guide road for restraining the moving direction of a liquid that naturally flows down and pressure regulating air passages extending along the guide road formed on both sides of the guide road is disclosed in Japanese Patent Application No. 5-73393. It is known from the issue.

[0007]

With respect to the liquid-absorbent fibrous material described in this publication, the applicant of the present application has continued trial manufacture and research using various materials. The horizontal width of the flat pipe tape described above is merely a matter of choice, but as the horizontal width increases, the amount of residual air increases and it becomes difficult to subdivide the air pool. There is a drawback that the flow becomes non-uniform when it grows large while the air pocket remains.

Therefore, the applicant of the present invention, in producing a flat pipe having a large flow passage width, forms a uniform passage cross section along the moving path of the fluid in order to cause the liquid to flow in a state of being spread in a plane. I came to realize that it had to be done. For the fluid movement path device, it was studied to use a regulation sheet (Jukoku 7-8996) in which strip-shaped partition wall element layers arranged in parallel between a pair of sheet materials are interposed. These conventional examples are based on a structure in which a heat medium liquid is made to flow down through a gap formed between a pair of materials, and the flowing-down direction of the heat medium liquid is regulated.

According to this conventional example, even if the flow rate is set to be relatively large, there is an advantage that the regulation effect is maintained to some extent. In the conventional example, one base material is covered with a flat cover sheet, and when the flow rate is large, the upper cover sheet swells and deforms to release the internal pressure. However, although the seat adopts a configuration that takes into consideration the possibility of mass transportation of fluid in advance, it is difficult to accurately adjust the flow rate of each route, and the flow rate (movement There is a drawback that the thickness of the fluid is not uniform. There are many places where the cover sheet drips and comes into contact with the substrate side, and when the flow rate is large, the sheet rises greatly. The cause of the sheet sagging is
There is elongation of the sheet due to thermal expansion and elongation due to negative pressure with a decrease in the amount of fluid in the path. Further, even when the movement of the fluid is stopped, the phenomenon that the cover sheet adheres to the bottom of the path and blocks the path due to the liquid remaining in the path was observed. In such a situation, when the sheet is used as a heat exchange flat pipe, the performance (heat exchange) and response (heat transfer) vary, and when it is used as a liquid transfer flat pipe, the flow rate at the end face side It was a cause of trouble such as unevenness. Further, the sheet is weak against the rolling force applied from one side, and due to the structure, the flat pipe easily clogs when a load is applied, and an unbalanced state occurs in the flow rate.
It was experienced that this imbalanced state was not constant and changed irregularly with the passage of time, and it was not possible to carry out balanced and accurate fluid transfer management.

An object of the present invention is to provide a fluid regulating sheet which can withstand internal pressure strongly even if the flow rate of the fluid fluctuates greatly and is resistant to breakage and excellent in pressure resistance.

Another object of the present invention is to provide a pressure-resistant fluid-regulated transfer sheet having a pressure distribution function in which fluid paths are electrically connected to each other through a partition element having fluid permeability and a pressure dispersion function capable of quickly adapting to an increase or decrease in internal pressure is provided. To provide.

[0012]

In order to achieve the above object, according to the first aspect of the present invention, the pressure-resistant fluid-regulated transport sheet has excellent tensile strength and is provided with flexibility to be opposed to each other. A pair of tensile resistance sheet-like elements, arranged in parallel between these sheet-like elements, adhered to each sheet-like element,
A partition element for restricting movement of the planar elements in a direction away from each other, parallel surrounding passages formed between the planar element and the partition element, and a planar element bonded to an outer surface of the planar element. The waterproof resin tube is extruded so as to form an outer waterproof layer that surrounds the whole and is integrally welded to the outer surface of the planar element.

Further, according to the second aspect of the present invention, a pair of tensile resistance sheet-like elements having excellent tensile strength and having flexibility provided opposite to each other and a pair of the sheet-like elements having opposing surfaces are provided. The ridge-like protrusions which are arranged in parallel in advance and form a space in parallel with each other and the ridge-like protrusions of the respective surface elements are superposed so as to occupy a part of the space of the opposed surface elements. Extruded to form an enclosing passage of arbitrary cross section formed by adhering the contact portion of the projection and the surface element and an outer waterproof layer that surrounds the entire surface element, and on the outer surface of the surface element. A pressure-resistant fluid-regulated transport sheet including a waterproof resin tube to be laminated can be obtained.

[0014]

The pressure-resistant fluid regulation conveying sheet of the present invention is installed in any posture. Specifically, it is installed substantially horizontally or vertically with a gradient if necessary. The cross section of the surrounding path can be freely set by appropriately selecting the width and thickness of the ridge-shaped projection. Further, the cross section of the surrounding passage can be changed in order from the side closer to the side portion of the pipe.

As the fluid pressure in the enclosed passage increases, the surface element expands outward. A partition element is interposed between the opposing surface elements, and the partition element limits the movement amount of the surface element, and as a result, the internal pressure acts as a tensile force on the surface element.

Due to the structure that resists the internal pressure by utilizing the tensile resistance of the planar element, even if the cross-sections of the surrounding passages are not the same, the planar element uses the internal pressure between each partition element as a unit. The deformation is symmetric along the area element.

With the above-mentioned structure, even if a part of the partition wall element is damaged, it has almost no effect on the entire structure of the pipe, and this part does not cause the damage. That is, although the opposing sheet-like elements become unconstrained due to the preceding breakage of the dividing wall, the respective sheet-like elements are further held by the adjacent dividing wall elements to cause the bridge deformation in which the span is extended. The tensile strength of the sheet-like element is selected in consideration of the occurrence of such a situation.

If the partition element is in the form of a ridge, it is possible to limit the amount of expansion deformation of the planar element. If this ridge-shaped projection structure is adopted, there is an advantage that the surrounding passage is unlikely to be closed when pressure is applied from the outside.

If the partition element is fluid permeable,
This partition element also plays a role of trapping the air remaining inside, and has an advantage that air lock hardly occurs. Further, the pressure can be moved between the surrounding passages, and when the same type of fluid is flowed through one sheet, the self-pressure adjusting function works conveniently. When the planar element and the partition element are made of a fluid-impermeable material, each surrounding passage can be independent of the other, and different surrounding fluids can also flow in each surrounding passage.

The sheet-like element has excellent tensile strength and has a relatively small amount of extension when subjected to an internal pressure. If a high-density non-woven fabric is used for the planar elements and a non-woven fabric with a lower density than the planar elements is used for the partition elements, the planar elements will bulge and deform outward under internal pressure, while the partition elements will be in the sheet thickness direction. And functions to limit the spread deformation of the planar element. You can use various types of materials,
Also, the combination of constituent materials is a matter of choice. Hereinafter, the pressure-resistant fluid regulation conveying sheet of the present invention will be specifically described with reference to the accompanying drawings.

In the example shown, the partition element is pre-integrated with the planar element. As a method of forming the partition wall element with respect to the planar element, it is possible to weld a strip material prepared in advance to the planar element or roll the planar element itself into an uneven shape and use the protruding portion as the partition element. it can.

It has a can structure that is stable against internal pressure.
