When the seat is in operation, the fluid initially supplied on the seat is
It gradually spreads from the supply point and flows while wetting the sheet surface. When the sheet and the fluid are intimately intimate with each other, there is regularity in the movement of the fluid, and the behavior is maintained. However, it takes time for the surface of the sheet to be saturated, and the behavior of the fluid in the process is not always regulated. In particular, if the sheet has a material layer that is highly water-retaining or water-absorbing, it takes a considerable amount of time before the responsiveness (consistency of flow performance between the fluid supply side and the fluid outflow side) occurs due to the sheet's regulation effect. It has the drawback of requiring time. Further, there is a certain restriction on the accuracy of the train-set performance, and it becomes difficult to maintain the train-set accuracy when the response speed is increased, and it is difficult to satisfy these two requirements at the same time.

御部材は構成されている。[Means for Solving the Problems] A large number of grooves are provided in parallel on the surface of a base material along the main flow direction of a fluid to form a plurality of main flow regions, and these main flow regions are mutually separated by interposing a sub flow region. It adopts a configuration that connects horizontally. The plurality of grooves forming the main flow region and the sub flow region each form a capillary passage, and the fluid flow control member is configured such that these regions cover the surface of the member.

細流の後を正確にたどり急速に流動する。The groove of the mainstream capillary passage forming the mainstream region extends in the moving direction of the fluid. Fluid is supplied to the mainstream region or the sidestream region. The supplied fluid is quickly captured in the mainstream capillary passage, and the capillary action of the mainstream capillary passage forms a large number of rapidly preceding capillaries along the mainstream capillary passage. These capillary flows draw a very clear mainstream path on the member, and the mainstream with a large flow rate will fill the range of the mainstream region later. The flow of the main stream following the preceding phenomenon of the capillary flow flows rapidly after accurately following the capillary flow due to the familiarity between the fluids.

時に進行していく。A mainstream region is rapidly and accurately formed on the surface of the member, and in parallel with this phenomenon or subsequent to this phenomenon, the diffusion of the fluid from the mainstream region to the substream region rapidly progresses. Depending on the positional relationship between the mainstream capillary passage and the sidestream capillary passage, the capillary flow in the initial mainstream region may enter the sidestream capillary passage in the sidestream region at the same time, or after the mainstream is formed in the mainstream region, the substream flows from this mainstream. A capillary flow is formed in the flow region and is guided by the side flow region capillary flow to determine whether a part of the main flow diffuses laterally. In the former case, the fluid advances on the member surface from the fluid supply side to the fluid outflow side,
In the latter example, there is a difference that a regulated main flow is generated early from the fluid supply side to the fluid outflow side. However,
If the level setting of the sidestream region is changed, these two phenomena will proceed simultaneously.

を形成する。Further, since the parallel grooves forming the sidestream capillary passages are arranged so as to intersect with the grooves of the mainstream capillary passage, the movement of the fluid along the sidestream capillary passage in the longitudinal direction is in the mainstream capillary passage. It is blocked or limited compared to the movement of fluid along it. Therefore, the sub-flow capillary passage serves as a resistance surface and forms a deceleration region for the flow of fluid in the same direction as the main-flow capillary passage.

との関係で選択する必要がある。The flow rate of the fluid flowing through the sidestream capillary passage is
The larger the flow rate of the fluid moving through the mainstream capillary passage, the smaller the flow rate of the fluid moving through the mainstream capillary passage. Therefore, the shape of the groove of the sidestream capillary passage,
Specifically, the design such as the width and depth of the groove, the level of the groove bottom, the width dimension of the side flow capillary passage, etc., must be selected in relation to the form of the groove of the main flow capillary passage.

The mainstream capillary passage takes the form of a recessed groove. If the amount of fluid flowing through the mainstream capillary passage is small, the upper portion of the sidestream capillary passage is exposed above the fluid surface of the mainstream capillary passage. If the level of the groove bottom of the mainstream capillary passage is set higher than that of the sidestream capillary passage, the mainstream capillary passage is raised in a ridge shape with respect to the sidestream capillary passage, and the sidestream capillary passage has the shape of a depressed groove. Present. In this structural example, the fluid supplied to the sidestream capillary passage is formed by a lateral capillary flow in the process of moving through the sidestream capillary passage and is taken over by the mainstream capillary passage to diffuse the fluid into the mainstream capillary passage. Occurs.

生じても速やかに回復する。The main and secondary flow capillary passages can also be arranged along the same plane. In this case, the ridge-shaped projection and the recessed groove are not formed. In any of the three-dimensional or planar arrangement of the main / substream capillary passages, the substream capillary passages form the communication passage between the adjacent mainstream capillary passages, while Form a deceleration area that restrains the sides. Therefore, even if some cause for disturbing the flow of the fluid occurs, the fluid is always held in the groove by the capillary action of the groove while moving between the main flow capillary passage and the auxiliary flow capillary passage, and at the same time, The fluid can freely flow on the surface of the fluid flow control member by bypassing the sidestream capillary passage. As a result, the flow rate distribution of the fluid covering the surface of the fluid flow control member does not change significantly, and even if turbulence occurs, it recovers quickly.

It When the fluid flow control member is used as a heat exchange device, if the volume of the groove is set large, the amount of fluid held in the flow passage increases, and if the heat exchange device is a snow melting device, the amount of heat held increases.

る。If the sidestream capillary passage is lower than the upper surface of the exposed fluid stream flowing through the mainstream capillary passage, ie, below the exposed fluid surface, the lateral grooves act as a means of moderating the exposed stream, Areas having different speed differences are adjacently and alternately located in the exposed fluid flow.
This flow has regularity, and the flow direction of the fluid is regulated.

成される。If an opening is provided in the wall of the groove of the secondary flow capillary passage, this opening functions as a communication passage for connecting adjacent grooves to each other. If these openings are aligned vertically,
The openings can be regarded as longitudinal grooves in the sidestream capillary passage.
The presence of the longitudinal groove helps to reduce the retarding resistance of the sidestream capillary passage. If a vertical groove is provided in the side flow capillary passage, a lateral flow is always formed in the side flow capillary passage.

Further, it is not necessary to use the same structure for the main flow capillary passage and the auxiliary flow capillary passage, and the structural form can be changed between adjacent ones.

1 shows a positional relationship between a mainstream capillary passage 1 and a sidestream capillary passage 2 formed on an upper surface of a base material. Mainstream capillary passage 1
The sidestream capillary passage 2 is located at the side of the mainstream capillary passage, the mainstream capillary passage is disposed on both sides of the sidestream capillary passage, and the sidestream capillary passage is disposed on both sides of the mainstream capillary passage. The width and depth of the groove are minute and fine. In the example shown,
The mainstream capillary passage 1 is composed of a large number of fine grooves 1a extending in parallel in the longitudinal direction in which the fluid flows. The sub-flow capillary passage 2 is composed of a large number of fine grooves 2a that intersect the grooves of the main-flow capillary passage and extend in parallel in the lateral direction.

滑に移動していく。The fluid is supplied to the mainstream capillary passage 1 or the sidestream capillary passage 2. The fluid supply point does not have to be at the end of these capillary passages, but may be at an intermediate position of the passages. Although the flow rate of the fluid supplied to the fluid flow control member is naturally limited depending on the usage form of the fluid flow control member, the installation posture of the fluid flow control member is not limited to horizontal, tilted, or vertical, and in principle is free. The movement range of the fluid due to the capillary phenomenon is wide, and the fluid moves smoothly even if some irregularities occur on the surface of the member.

In this example, the groove 1a of the main flow capillary passage is located lower than the groove 2a of the side flow capillary passage. Therefore, the supplied fluid first has a capillary flow along the groove 1a of the mainstream capillary passage 1, and subsequently the mainstream of the fluid follows these capillaries to move. When the surface level of the main capillary flow reaches the height indicated by A in FIG. 7,
A lateral capillary flow is formed along the groove 2a of the side flow capillary passage, and a part of the main flow flows into the side flow capillary passage.
At this time, due to the surface tension of the fluid, the fluid flowing into the sidestream capillary passage adheres to the side wall, and the side wall is difficult to be exposed even if the flow rate increases or decreases. B of FIG. 7 shows a state in which the surface of the fluid is dented due to surface tension.

Under these circumstances, the sidestream capillary passage is on the side of the mainstream capillary passage and forms a deceleration region for fluid moving along the mainstream capillary passage. If the deceleration regions are located on both sides of the main flow region, a boundary region is formed between them due to the velocity difference, and the flow direction of the fluid is limited to the direction of this boundary region.

発し易い雰囲気での使用には必要な構造である。FIG. 3 shows a structure in which an orifice 3 is formed in a vertical direction on a side wall of the sidestream capillary passage 2 and adjacent upper and lower grooves are electrically connected to each other. These orifices are aligned in the vertical direction to form continuous vertical grooves. Since the fluid moves along the groove in the vertical direction, the fluid in the groove of the sidestream capillary passage does not stay and a constant flow is formed. Similarly, an orifice can be formed laterally in the side wall of the mainstream capillary passage 1 so that the grooves of the adjacent mainstream capillary passages can be connected to each other at appropriately spaced positions. In the figure, reference numeral 4 indicates a weir installed in the groove of the mainstream capillary passage. A small amount of fluid can be stored between the weirs, and it is also effective in reducing the moving speed of the preceding capillary flow in the initial operation described above. When the surface area of the fluid flow control member is large and it is necessary to limit the rapid growth of the capillary flow and its spread over the entire surface, it is necessary to arrange such weirs appropriately and It is possible to shorten the diffusion time difference (distance between the leading portions). This structure is necessary for use in an atmosphere where the fluid easily evaporates.

る。The groove 2b of the sidestream capillary passage 2 shown in FIG. 5 is located lower than that shown in FIG. 4, and the groove 2c of the sidestream capillary passage 2 shown in FIG. 6 is located lower than that shown in FIG. is there. According to the structures shown in FIGS. 4 and 5, the side flow capillary passage is entirely ridged with respect to the main flow capillary passage, and the main flow capillary passage is entirely formed with a depression. The main-flow capillary passage and the secondary-flow capillary passage can be formed so that the tip ends of the groove walls of these capillary passages are located in the same plane. In the example of FIG. 6, the main-flow capillary passage is entirely ridged with respect to the sub-flow capillary passage, and the sub-flow capillary passage is entirely hollow. If the degree of depression of the sub-flow capillary passage is set to be large, the flow rate of the fluid along the sub-flow capillary passage may be larger than the flow rate of the fluid along the main-flow capillary passage.
