[0001]
[Industrial application fields]
The present invention relates to fluid regulating and conveying means for restricting the flow of fluid in a controlled state, and more particularly to fluid medium regulating and conveying means for regulating the moving direction of the flowing medium and causing it to flow evenly. Therefore, the regulation conveying means according to the present invention can be used for heat exchangers, evaporators and similar equipment.
[0002]
When the fluid regulation conveying means is used by being attached to the roof, it is possible to remove snow from the roof or melt snow by flowing warm water along this means. In summer, it can be used as a heat collecting sheet for collecting solar heat and as a cooling sheet for roofs and walls. When installed on the inner wall side of a building, the inner wall surface functions as a heat exchange surface for air conditioning / temperature management. The fluid regulation conveying means can itself be used as a building material of a building. The fluid regulating / conveying means is manufactured as a film body, and a film structure having a surface with heat exchange performance can be constructed by using the film body. The fluid regulation conveying means may be attached to the board material and used as an assembly type connection unit.
[0003]
Further, the regulation conveying means of the present invention is a member for accelerating the diffusion of fluid, for example, as a liquid regulation conveying means that also serves as a cultivation floor that supplies and appropriately distributes the cultivation liquid, or is embedded in the soil. It can be used as a water retention (water supply) and drainage sheet. When the fluid regulating / conveying means is used by being buried in a plane in the ground, cold water can be artificially obtained by flowing water along this member. Moreover, the form of embedding is various, and it is also possible to store underground heat through the fluid leveling and conveying means buried in the soil. If a sheet is laid on the road surface, it becomes a snowmelt road surface, and if it is laid on the foundation of the building, it can be used as a means of collecting spring water.
[0004]
When the fluid regulation conveying means is moored underwater, floated on the surface of the water, or installed in a state immersed in water, heat exchange is performed via the water contact surface by flowing a heat medium along this member. .
[0005]

[Prior art]
In order for the liquid to flow in a state of being spread in a flat shape, an equal passage section must be formed along the fluid movement path. Conventionally, in such a fluid movement path device, laminated laminate sheets (Japanese Patent Application Nos. 7-228534 and 7-48040) having an intermediate intervening layer of a fibrous material, or a pair of sheet materials are arranged in parallel. A regulation sheet (Act No. 7-8996, No. 1-7330) having a belt-like spacer layer is used. 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. FIG. 13 of the accompanying drawings clarifies the basic structure of the former conventional example, and FIG. 14 illustrates the latter conventional example.
[0007]
[Problems to be solved by the invention]
However, according to these conventional examples, in the former method, first, the surface laminate layer 2 is rolled and welded to the base material 1 in a streak form, so that the resin enters the path provided in advance when the molten resin is pressed, As a result, it is not possible to ensure a required flow path cross section. Accordingly, there are significant limitations on the flow rate of the carrier fluid, and there is a drawback that the effect of regulation is lost when the flow velocity is large. The feature of this sheet is that the path 3 along the exposed liquid retaining layer forms the main flow, and the lower portion of the surface streaky laminate layer 2 forms the underlying path 4.
[0008]
According to the latter method, there is an advantage that a certain level of effect is maintained even if the flow rate is set to be relatively large as compared with the former method. This regulation sheet is configured by covering one base member 5 with a flat cover sheet 6 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 this sheet 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 for each path 7, and the flow rate of the fluid flowing through each path There is a drawback that (the thickness of the moving fluid) is not uniform. FIG. 15 shows a state in which the cover sheet 6 has come into contact with the substrate side (solid line) and a state in which the sheet has been lifted due to a large flow rate (two-dot chain line). 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. In such a situation, when the sheet is used as a heat exchange device, performance (heat exchange) and responsiveness (heat transfer) vary, and when it is used as a liquid transport sheet, the flow rate at the end face side is inadequate. It was the cause of obstacles such as being uniform. Furthermore, the sheet is weak against the rolling force applied from one side, and structurally, when a load is applied, the flow path is easily clogged, 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.
[0009]
An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to provide a structure that can be easily manufactured and has a path of a flow path cross section corresponding to a required fluid flow rate and flow velocity at every necessary interval. An object of the present invention is to provide a fluid regulation conveying means having pressure resistance that is evenly distributed even when a compressive load is applied and the flow path is not easily blocked.
[0010]
In addition, the object of the present invention is to provide a function of deforming so that a flow cross section corresponding to the flow rate can be obtained even if the flow rate of the fluid fluctuates greatly, and to provide a self-adjusting action that adapts to the increasing internal pressure. It is an object of the present invention to provide a fluid regulation conveying means incorporating a conveyance path having a structure difficult to perform.
[0011]
Another object of the present invention is to provide a fluid regulation conveying means having a function of allowing fluid paths to conduct with each other and adapting to an increase or decrease in internal pressure.
[0012]
Another object of the present invention is to provide a fluid leveling / conveying means having a feature capable of simultaneously achieving a plurality of the aforementioned objects.
[0013]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, the fluid regulating and conveying means includes a ridge-like protrusion provided in parallel on the substrate and a parallel arrangement formed between these ridge-like protrusions. Using a pair of planar elements with spaces, the ridge-like projections of each planar element are overlapped so as to occupy a part of the space of the opposing planar elements, and an enclosed passage with an arbitrary cross section is required inside They are formed at intervals.
In order to achieve the above object, according to the second aspect of the present invention, the fluid regulation conveying means includes ridge-like protrusions provided in parallel on the substrate, and the space between these ridge-like protrusions is a fluid. In a path space between a planar element on one side forming the movement path of the liquid, a cover member covering the fluid movement path, which is disposed relative to the planar element, and an adjacent ridge-shaped projection It is comprised with the raising / lowering protrusion with which the inner side surface of the cover member was mounted | worn so that a position change was possible relatively with respect to the base-material surface of the planar element which penetrates.
In order to achieve the above object, according to the third aspect of the present invention, the fluid regulation conveying means includes a liquid-permeable ridge-like protrusion provided in parallel on the substrate and the ridge-like protrusion between the ridge-like protrusions. Using a pair of planar elements with parallel spaces formed, the ridge-like projections of each planar element are overlapped so as to occupy a part of the space of the opposing planar elements, and an arbitrary cross section inside The surrounding passages are formed at every necessary interval, and the respective surrounding passages are configured to have a liquid mutual conduction relationship via the ridge-like projections.
[0014]
[Action]
The fluid regulation conveying means of the present invention is installed in an arbitrary posture. Specifically, it is installed substantially horizontally or vertically, with a gradient if necessary.
A pair of planar elements is used as a component. When two planar elements are put together, the flow cross section of the adjacent enclosed path changes by the operation of shifting in the horizontal direction. By this operation, the enclosing path of the required flow rate cross section can be passed over the entire surface of the fluid regulation conveying means.
[0015]
The planar elements can be secured to each other in any way. For example, the projection of the planar element can be bonded to the opposing planar element. The bonding location is not all projections, but can be bonded along the ridges selected at appropriate intervals. Of course, the edges of the planar elements can be welded together to form a bag-like structure so that one planar element can be translated in a direction away from the other planar element. When the ridge-like protrusions are fixed to the planar element, if the ridge-like protrusions are made of a liquid-permeable material, for example, a fibrous material, a foamed resin material having an 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 protrusions of one sheet material are not bonded to the other sheet-like material, the ridge-like protrusions will slide according to the shape of the corrective conveying means perpendicular to the ridge-like protrusions. The moving sheet material can be flexibly deformed, and the sheet material on the compression side is not wrinkled.
[0017]
If the ridge-like projections of the planar material are welded and integrated with the opposing planar material, even if a large load is received from the outside under a flat usage pattern, the corrective conveying means will be an integral structure. A tough flat pipe is formed that resists and does not break easily.
[0018]
In the above-mentioned example in which the ridge-like projection of one planar material can move relative to the other planar material, the ridge-like projection is in a position corresponding to 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-described lifting projection structure is adopted, the fluid regulation conveying means is suddenly bent, the wind is locally deformed, the upper part is Even if a sudden pressure change occurs along the route when a person walks or a vehicle travels, the ridge-like protrusions themselves pass through, and the lifting and lowering protrusions move up to disperse the pressure. The original equilibrium state is reproduced. If such self-regulating performance is utilized, the fluid regulation conveying means can be used for special applications such as a snow melting road and a snow melting sidewalk.
Hereinafter, the usage example of the fluid regulation conveying means of the present invention will be specifically described with reference to the accompanying drawings.
[0020]
【Example】
FIG. 1 shows an example of the configuration of a fluid regulation conveying means according to the present invention. The fluid regulation conveying means includes a pair of planar elements 10 and 10. Each planar element 10 includes a base material and corrugated protrusions 11 and 11 provided in parallel on the base material, and parallel spaces, that is, fluid movement paths 12 and 12 are formed between the corrugated protrusions. Has been. The planar elements are overlapped so that the ridges of each planar element occupy part of the space of the opposing planar elements. FIG. 2 shows a specific example of the fluid regulation conveying means constructed by superposing a pair of planar elements.
[0021]
The planar element in FIG. 2 shows a state in which the ridge-like protrusions 11 are combined so as to be positioned at the center of the spaces 12 and 12. Therefore, the surrounding passages 13 having the same cross section are formed at equal intervals inside. If the planar elements are shifted and combined horizontally, the cross section of the surrounding passage 13 increases or decreases by an amount corresponding to the shifted amount. If the width of the ridge-like protrusions 11 of the planar element on one side, the interval between the ridge-like protrusions, and the position and width of the space 12 of the planar element on the other side are appropriately selected, an enclosed passage having an arbitrary cross section can be formed. Fluid regulating and conveying means arranged at appropriate intervals can be obtained.
[0022]
FIG. 3 shows a state where the unconstrained planar elements are expanded by receiving the 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 protrusion and the planar element facing each other can be bonded in advance at an appropriate interval.
[0023]
The substrate of the planar element 10 and the ridge-like protrusion 11 may be made of different materials. Even when it is made of the same kind of material, it is possible to use different materials with different density, different water retention, and different water permeability for each base material and ridge-like protrusions, and change the physical properties of both. is there. 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 illustrated planar element includes a laminate resin layer 14 on the outside.
[0024]
FIG. 4 shows an example of a fluid regulation conveying means in which the lower planar element 20 is made of a hard material and the upper planar element 20 ′ is made of a water-permeable material. The fluid regulation conveying means of this example can be used as a snow melting road or a snow melting sidewalk. FIG. 6 shows a state in which the fluid regulation conveying means is laid on the road bed R. Unlike the example shown in FIG. 3 in which the upper planar element floats due to the internal pressure applied to the surrounding passage, the fluid regulating conveying means in this example is such that the upper planar element 20 ′ leaks upward from the inside at the same position. The surface flow 25 then spreads along the surface of the upper planar element or flows in the direction of the internal surrounding passage 23. This surface current is quickly absorbed by the snow particles and a rapid heat exchange takes place. The snow melts quickly or becomes a sherbet, and the heat transfer fluid is supplied to the snow that further accumulates through the sherbet to promote snow melting.
[0025]
The lower and upper planar elements 20, 20 ′ are provided with a rigid ridge-like protrusion 21 and a water-retaining ridge-like protrusion 21 ′, and enter the space 22 of the respective planar elements to enter the surrounding passage 23. Forming. A laminate resin layer 24 is coated on the base material of the lower planar element 20.
[0026]
4 to 6 can be used as a drainage sheet, a water supply sheet, a water retention sheet, a groundwater collection sheet, etc. by being buried in the soil.
[0027]
7 to 9 show an example of an underground heat storage device using the fluid regulation conveying means according to the present invention. 7 is a longitudinal sectional view taken along line VII-VII in FIG. 8 is a longitudinal sectional view taken along line VIII-VIII in FIG. 7, and FIG. 9 is a transverse sectional view taken along line IX-IX in FIG.
In this underground heat storage device, a continuous underground wall W is constructed on the upper part of the impermeable layer S, the ground surrounded by the underground wall is excavated, and then the heat storage material 31 is spread by a roller rolling operation, and the roller rolling surface The fluid regulation conveying means 30 is laid in parallel on the top, the heat storage material 31 is further laid on the upper part, and the operation of laying the fluid regulation conveying means 30 on the upper part is repeated, so that the multistage heat exchange surface 30 and the heat exchange surface are interposed between them. It is formed by repeating the interposed heat storage layer. 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 sides of the underground wall W, and the fluid regulating and conveying means 30 communicate with each other between the two water tanks. In the illustrated example, the heat medium introduced into one water tank 32 reaches the water tank 33 on the opposite side through the fluid regulation conveying means 30, and heat exchange is performed with the heat storage material 31 during the movement. The head in the aquarium is adjusted by the aquifer level inside the underground wall and the degree of load, and the flow rate of the fluid regulation conveying means is selected.
This case is currently being studied in urban areas as a measure for effective use of parking lot underground. When building a building or the like on site after use, it is easy to return to the current state.
[0029]
10 and 11 show an example of a large heat exchanger installed in a water channel. 11 is a longitudinal sectional view taken along line XI-XI in FIG.
In the figure, reference numeral 40 denotes a heat medium supply pipe, 41 denotes a recovery rod, 42 denotes a fluid regulating / conveying means installed in a bent state, and 43 denotes a support for suspension. The principle of this heat exchange device can be used for heat exchange between liquid / liquid and liquid / gas. For example, if fresh seawater introduced through a filter is passed through the fluid regulation conveying means and used waste warm seawater is passed through the water channel, efficient low-temperature heat exchange is performed between the two.
[0030]
In such a configuration, since the buoyancy acts on the immersed fluid regulating and conveying means, a large load is not easily applied to the fluid regulating and conveying means even if the scale is increased, so that a large-scale heat exchange system can be constructed. This method can also be diverted to a heat storage tank.
