Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement technology for a ruled line sheet manufactured by using a flexible sheet material.

[0002]

[Prior art]

 The applicant of the present invention has attempted various methods for forming the flow regulation line using a liquid-retaining material such as a non-woven fabric. A conventional heat exchange sheet is a sheet having a structure in which a liquid is used to flow down from one side of the sheet to the other side. Therefore, the main focus is to arrange the lyophilic path and the lyophobic path alternately to separate the falling medium in an orderly manner.

[0003]

[Problems to be solved by the device]

 According to such a conventional heat exchange sheet, a large temperature gradient appears on the sheet surface from one side of the sheet to the other side, or the concentration of the liquid is not constant. It cannot be used for applications where heat exchange / medium supply is required to maintain a comparatively gentle temperature gradient on the sheet surface.

An object of the present invention is to provide a sheet that is used in an environment where the use / conditions that cannot be handled by such a conventional heat exchange sheet are required.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a line-shaped adhesive covering layer for fixing the liquid retaining layer in a consolidated state is formed in an arc shape in cross section, and the gutter having the arc shape in cross section is arranged between the liquid retaining layers to form a sheet. Are configured.

[0006]

[Effect of action and device]

 By adopting such a configuration, a flow path of the moving fluid is formed between the liquid retaining layers, and the moving fluid flowing through the flow path enters and leaves the liquid retaining layer through a large number of communication passages.

The characteristics of the flow path, for example, the flow rate, the fluid temperature, and the flow velocity can be controlled to appropriately manage the state of the fluid held in the liquid retaining layer. Specifically, when the normalizing line sheet of the present invention is used as a cultivation bed for hydroponic cultivation, it is possible to centrally manage cultivation beds in a wide area under relatively uniform conditions. When used as a snowmelt sheet, the amount of carrier water corresponding to the amount of snowfall can be supplied not only at the upper end portion of the liquid retaining property, but also at the upper end portion, from a number of points along the route. The surface temperature can be controlled relatively easily via the distribution channel. In the case of planar use such as the above-mentioned hydroponic cultivation, if the direction of the moving fluid flowing through the distribution path is opposite to that of the adjacent distribution path, stirring of the moving fluid occurs over the entire surface of the sheet.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an explanatory view showing the basic structure of a ruler wire sheet according to the present invention. In the illustrated example, a liquid retaining layer for the moving fluid is covered with a lyophobic material to form a streak-shaped liquid retaining layer 1 and an adhesive coating layer 2. The adhesive coating layer 2 is located between the line-shaped liquid retaining layers 1 and fixes the liquid retaining layers in a compacted state. This adhesive coating layer forms a trough 3 having an arcuate cross section with a hollow center and raised on both sides, and slit-like weirs 4 or passage openings 5 are formed on the walls on both sides of the trough 3 at intervals. Has been formed. The arc-shaped cross-sectional shape of the adhesive coating layer can be adjusted by controlling the temperature and supply amount of the fluid adhesive supplied to the surface of the liquid retaining layer, and the rolling amount / conveying speed of the pressure roller. Generally, when an adhesive having a relatively high viscosity is used, the curvature of the arc-shaped cross section can be set to be larger than that when an adhesive having a relatively low viscosity is used.

A substrate 10 can be provided on at least one surface of the liquid retaining layer 1. The base material 10 is made of a metal plate such as stainless steel or a baked coated iron plate, a resin-coated metal plate, or a resin sheet or a laminated resin sheet. Can be set.

The substrate can use the outer surface as a heat exchange surface for heat collection / heat radiation / cooling / evaporation, and the surface on the side provided with the liquid retention layer for heat collection / heat radiation / cooling / evaporation / concentration. Can be used as a heat exchange surface. Various heat media can be used as the moving fluid. When a hydroponic culture solution is used as the heat medium, the streak-shaped liquid retaining layer 1 is used as a cultivation bed for hydroponic culture. When used as a snow melting device, the streak-shaped liquid retaining layer 1 and the gutter 3 are used as a carrier passage for a carrier moving fluid of snowfall particles.

The widths of the stripe-shaped adhesive coating layer 2 and the stripe-shaped liquid retaining layer 1, and the slit-shaped weir 4 or passage opening 5 can be freely changed in the manufacturing process. The formation of the slit-like weir 4 or the perforation of the passage opening 5 can be performed at the same time when the above-mentioned roller rolls. In the figure, the impregnation density of the adhesive is represented by the density of dots.
