Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a means for restricting the movement of a heat medium liquid, and more particularly to a flow-down type heat medium capable of stably forming a regular flow. The present invention relates to a liquid movement regulating means. 2. Description of the Related Art A flow-type heating medium liquid regulating means for flowing a heating medium liquid downward from above a base material along the base material is well known, for example, from Japanese Utility Model Publication No. 62-7971. It has become. Such a conventional heat collector is generally provided with a vertical flow path, and the shape of the base material is preferably extended long for the purpose of heat exchange with the heat medium liquid. is there. As the path lengthens in the longitudinal direction, the device necessarily increases in length, and accordingly, the gantry structure also needs to be increased in rigidity. [0003] In a structure in which the flow-down path is inclined sideways in a staggered manner and the flow of the heat medium is controlled while moving the liquid medium to the left and right, if the thickness of the bank-shaped guide path is small, heat is generated from the middle of the path. The medium liquid easily falls off. If the flow is short-circuited between the paths, it is difficult to return the flow to its proper state. [0004] Means for restricting the transfer of the heat medium liquid according to the present invention are as follows.
A hydrophilic material that adheres a hydrophilic material alternately and obliquely from the heat medium liquid supply position to the downstream side, and protrudes like a ridge from the exposed hydrophobic surface of the substrate to guide the flow of the heat medium liquid. Forming a path. [0005] Since the hydrophilic material is staggered and stuck to the surface of the base material of the hydrophobic material, a hydrophilic flow path having a different property from that of the hydrophobic surface is formed. The supplied heat medium liquid is adapted to the material of the hydrophilic material and tends to flow along the ridge-shaped material of the hydrophilic material, so that the flowing direction of the heat medium liquid is restricted. As a result, the heat medium liquid does not move irregularly and flows down while maintaining a relatively stable state. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The means for restricting the transfer of a heating medium shown in the drawing has a flat base material 3 and a ridged material made of a hydrophilic material adhered to the surface of the base material. Thus, the hydrophilic flow paths 1 and 2 for guiding the heat medium liquid are formed. The base material 3 is made of a metal such as stainless steel or aluminum, a fiber reinforced polyester plate, a polycarbonate plate, a synthetic resin plate such as methacrylic resin, a glass plate or a ceramic material, or a silicon material. Or fluorine-based sheet materials can be used. A hydrophobic material is used for the substrate. [0008] The above-mentioned material is composed of a hydrophilic material. These materials include painting, silk-screen printing,
It can be adhered to the surface of the substrate 3 by a technique such as sticking or hot rolling. FIG. 1 shows a flow path pattern of the means for regulating the movement of the heat medium liquid. The flow merchandise 1 has a downwardly sloping portion, a receiving portion on the upstream side of the sloping portion, and a delivery portion 1 ′ on the downstream side opposite to the receiving portion. The flow merchandise 2 has a downwardly sloping portion, a receiving portion 2 ′ upstream of the sloping portion, and a transfer portion 2 ″ downstream from the receiving portion. The heating medium liquid is supplied to the surface of the base material using, for example, a liquid spraying means [0010] Figs.2 and 3 each show a specific example in which the above-mentioned flow regulating means is applied to a heat collector. Fig. 2 shows an example of an open flow-down type heat collector in which flow-down paths 1 and 2 are installed on the front side of a base material 3, and the flow-down path is covered by a transparent body 4. In the case of a falling collector,
A downflow path is provided on the back side.
