[Prior art]
A flat shaped hollow strip and a naturally falling or naturally flowing liquid composed of a liquid-absorbing fibrous material sandwiched between one flat wall and the other wall of the strip. A flat piping tape provided with an induction road for restraining the direction of movement and a pressure-regulating air passage extending along the induction road formed on both sides of the induction road is known from Japanese Utility Model Application No. 5-73393. ing.
[0007]
[Problems to be solved by the invention]
With respect to the liquid-absorbing fibrous material described in this published specification, the applicant has continued trial manufacture research using various materials. The width of the flat piping tape described above is merely a matter of choice, but as the width increases, the amount of remaining air increases, making it difficult to subdivide the air pool. There is a disadvantage that the flow becomes non-uniform if it grows large with an air pocket remaining.
[0008]
Therefore, when manufacturing the flat pipe having a large flow path width, the applicant of the present application must form an equal passage section along the fluid movement path in order to allow the liquid to flow in a flat state. I came to realize that I had to do it. For the fluid movement path device, it was examined to use a regulation sheet (Act No. 7-8996) in which a band-shaped partition wall element layer arranged in parallel between a pair of sheet materials was interposed. These conventional examples are based on a structure in which the heat medium liquid flows down through a gap formed between a pair of materials and the flow direction of the flowing heat medium liquid is regulated.
[0009]
According to this conventional example, even if the flow rate is set to be relatively large, there is an advantage that a certain degree of regulation effect is maintained. The conventional example is configured by covering one substrate with a flat cover sheet, and adopts a structure in which the upper cover sheet swells and deforms to release the internal pressure when the flow rate is large. However, although the seat adopts a configuration that takes into consideration the possibility of mass transport of fluids in advance, it is difficult to accurately adjust the flow rate of each route, and the flow rate (movement) of the fluid flowing through each route is difficult. There is a drawback that the thickness of the fluid is not uniform. It shows a state in which the cover sheet has come into contact with the substrate side and a state in which the sheet has been lifted due to a large flow rate. The cause of the drooping of the sheet includes the extension of the sheet due to thermal expansion and the extension due to the negative pressure accompanying the decrease in the amount of fluid in the path. In addition, even when the movement of the fluid was stopped, a phenomenon was observed in which the cover sheet adhered to the bottom of the path due to the liquid remaining in the path and blocked the path. When the sheet is used as a heat exchange flat pipe, performance (heat exchange) and responsiveness (heat transfer) vary, and when it is used as a liquid transfer flat pipe, the flow rate at the end face side Caused non-uniformity. In addition, the sheet is weak to the rolling force applied from one side, and because of the structure, when a load is applied, the flat pipe easily clogs, and an unbalanced state occurs in the flow rate, and this unbalanced state is not constant and time It has been experienced that it is irregularly changed with the passage of time, and it is impossible to carry out balanced and accurate fluid transport management.
[0010]
The object of the present invention is to prevent deformation even when the flow rate of fluid greatly fluctuates by providing a deformation function that proportionally expands the flow cross-section following this and a self-adjusting action that can adapt to increasing or decreasing internal pressure. An object of the present invention is to provide a flat pipe for transporting a fluid regulation having a structure.
[0011]
In addition to the above-described effects, another object of the present invention is to provide a fluid regulation having a pressure dispersion function that allows fluid paths to communicate with each other via a fluid-permeable partition wall element and to quickly adapt to the increase or decrease in internal pressure. It is to provide flat piping for conveyance.
[0012]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is arranged in parallel on a pipe base material in the form of a tube having opposite flat wall surfaces and inner walls of the opposite wall surfaces of the pipe base material in parallel. It has ridge-like projections that form a space, and the ridge-like projections on each wall surface are overlapped so as to occupy a part of the parallel space on the opposite wall surface, and an enclosed passage with an arbitrary cross section is required inside They are formed at intervals.
[0013]
[Action]
The flat pipe for fluid regulation conveyance of the present invention is installed in an arbitrary posture. Specifically, it is installed substantially horizontally or vertically, with a gradient if necessary.
[0014]
The cross section of the enclosing path can be freely set by appropriately selecting the width and thickness of the ridge-like protrusion. Further, the cross section of the surrounding passage can be changed in order from the one near the side of the pipe.
[0015]
The substrate wall surfaces can be fixed to each other by any method. For example, they can be bonded to each other via a ridge-like projection. The bonding location is not all projections, but can be bonded along the ridges selected at appropriate intervals. If the ridge-like protrusions are fixed to the substrate wall surface, if the ridge-like protrusions are made of a liquid-permeable material, for example, fibrous materials, foamed resin materials having open cell quality, various compounds, etc. If it is made of sintered metal, porous ceramic, etc., the pressure is released through the ridge-like projections.
[0016]
If the ridge-like projection of one planar material is not bonded to the other substrate wall surface, the ridge-like projection slides and moves according to the shape when bending perpendicular to the ridge-like projection. The wall surface can be deformed flexibly, and wrinkles do not occur on the base material wall surface on the compression side.
[0017]
If the corrugated projections of the base wall are welded and integrated with the opposing base wall, the corrective conveying means will be integrated as one even under a planar usage pattern even if a large load is applied from the outside. A tough flat pipe is formed that resists and does not break easily.
[0018]
In the above-mentioned example in which the ridge-shaped protrusion on one base wall surface can move relative to the other base-material wall surface, the ridge-shaped protrusion is in a position commensurate with the internal pressure while moving up and down as the path internal pressure increases and decreases. The left-right symmetry of the route can be maintained. For this reason, even if the internal pressure and the flow velocity fluctuate, the flow rate averaging operation and the regulation effect are maintained, and fluid can be transported with high accuracy.
[0019]
When the ridge-like projections are liquid permeable, or when the above-mentioned lifting projection structure is adopted, the flat pipe is suddenly bent, local deformation occurs due to the wind, or the upper part is Even if a sudden pressure change occurs along the route due to walking or running of the vehicle, the ridge-like projections themselves pass through, and the pressure is dispersed by the ascending and descending projections. The equilibrium state is reproduced. If such self-regulating performance is used, the flat pipe for conveying the fluid regulation can be used for special applications such as a snow melting road and a snow melting sidewalk.
Hereinafter, a usage example of the flat pipe for fluid regulation conveyance according to the present invention will be specifically described with reference to the accompanying drawings.
[0020]
【Example】
FIG. 1 shows a configuration example of a flat pipe for fluid regulation conveyance according to the present invention. The flat piping for fluid regulation conveyance is in the form of a tube provided with a pair of substrate wall surfaces 10 and 10. Each substrate wall surface 10 includes a substrate and ridge-like protrusions 11 and 11 provided in parallel on the substrate, and parallel spaces, that is, fluid movement paths 12 and 12 are formed between the ridge-like protrusions. Has been. The substrate wall surfaces are overlaid so that the ridge-like projections of the respective substrate wall surfaces occupy part of the space of the opposite substrate wall surfaces. The substrate wall surface of the tube-shaped flat pipe can be continuously manufactured as a tube-shaped material by, for example, an extrusion die. Alternatively, it can be processed into a tube shape by welding the side surfaces of the sheet, or a ridge-shaped projection is formed in advance on the base sheet, and a resin layer is laminated on the outer surface of the base sheet and processed into a flat pipe You can also
[0021]
The illustrated substrate wall surface shows a state in which the ridge-like protrusions 11 are combined so that they are located at the centers of the spaces 12 and 12. Therefore, the surrounding passages 13 having the same cross section are formed at equal intervals inside. If the ridge-like protrusions are shifted and combined, the cross section of the surrounding passage 13 increases or decreases by an amount corresponding to the shifted degree. If the width of the ridge-like projections 11 on the one side of the substrate wall surface, the interval between the ridge-like projections, and the position and width of the space 12 on the other side of the substrate wall surface are appropriately selected, the enclosed passage having an arbitrary cross section A flat pipe for fluid regulation transfer arranged at an appropriate interval is obtained.
[0022]
FIG. 2 shows a state in which the unconstrained base wall surfaces are expanded by receiving an internal pressure. In this state, the upper and lower ridge-shaped projections sufficiently restrain the moving direction with respect to the moving fluid, and allow the fluid to escape to the adjacent enclosing passages. Therefore, the sheet is swollen but locally expanded. Rather, the internal pressure due to excess fluid is evenly distributed throughout. The ridge-like protrusions and the substrate wall surface facing each other can be bonded in advance with an appropriate interval.
[0023]
The substrate wall surface 10 and the ridge-like protrusion 11 may be made of different materials. Further, the substrate wall surface can also be composed of a laminated composite layer rather than a single layer. Even when the substrate wall surface and ridge-shaped projections are made of the same material, materials with different densities, different water retention properties, and differences in water permeability are used for each substrate and ridge-shaped projections. Can be changed. For example, the ridge-like projections can be made from a nonwoven fabric rich in water retention, the base material can be made from a high-density nonwoven fabric, and both can be bonded together, or the nonwoven fabric can be rolled by a roller. The base material wall surface shown in the figure is made of the same kind of material as the ridge-shaped protrusions on the inner side, and is formed from the laminate resin layer 14 by extrusion molding on the outer side.

Processing conditions such as the amount of rolling and the extrusion speed are appropriately selected.

It is preferable that water is sprinkled on the inner side of the underground wall W before and after the laminating work so that the whole is kept in a water retaining state.
[0028]
Two water tanks 32 and 33 are installed on the opposite end side of the underground wall W, and a flat pipe 30 for fluid regulation conveyance communicates between these two water tanks. In the illustrated example, the heat medium introduced into one water tank 32 reaches the opposite water tank 33 through the flat pipe 30 for fluid regulation conveyance, and heat exchange is performed with the heat storage material 31 during the movement. .
