Description

Windable radiator and its installation method

The present invention relates to a winding heat sink and a method of installing the same. More specifically, the present invention relates to a heat sink used for floor heating or snow melting, which can be wound despite a hard surface, and is easy to pack, store, transport, and install. It is related to a heat sink which is hard to produce and its installation method. This heat sink is particularly suitable as a floor heating panel.

Background Art Conventionally, a floor heating technology for heating from the floor of a house has been proposed and put into practical use for the purpose of improving the habitability of a house in a cold district and a chill in a house in a warm district. For example, in a single house, a method of incorporating a floor heating panel between a crossbar and a bottom plate and on a base plywood laid on the crossbar is adopted, and in a apartment house such as a mansion or the like, directly or on a slab floor surface. A method of installing a floor heating panel (heat radiator) on a base plywood, etc., laid on the slab floor is employed.

The floor heating panel is made of, for example, an elongated plate-shaped body made of foamed resin, a groove is formed in one side of the elongated plate-shaped base, and a conduit or heating for heating fluid is provided in the groove. The thing of the structure which embedded the electric wire (wire) and coat | covered with the surface coating material, such as aluminum foil, on the surface is proposed. In addition, a structure in which a hard material such as a hard resin foam is used as a base, a groove is formed in one side of the base, a conduit or an electric wire is embedded in the groove, and the surface thereof is covered with a surface coating material such as aluminum foil. It is proposed. In order to construct a floor heating panel with such a structure, a factory is a method of manufacturing a floor heating panel in which a conduit or an electric wire is embedded in a groove engraved on one side of a long board-shaped molded product made of foamed resin and installed at the installation site. It is adopted.

The floor heating panel is selected from 300cm × 400cm for both length and width depending on the size of the installation place, but any one of length and width is 200cm or more from the viewpoint of packing, transportation, storage and constructability. At least one of the length and the width is adjusted to 200 cm or less, bent in the longitudinal direction or the width direction, transported to the factory, and the bent state is opened. However, there existed a fault, such as that the surface after installation was smooth and there was no nail holding force when the nail was fixed out.

In the case where the heating heating conduit or the floor heating panel on which the heating wire is arranged is bent and overlapped (wound) as it is, it is simply bent and overlapped (wound) as it is, and the portion of the conduit or the electric wire is bent, and breakage or disconnection occurs. For this reason, conventionally, a part of the wide bottom heating panel is bent over (a longitudinal end of a long body), and in the vicinity of the long body overlying part, some of the conduits or wires are removed from the groove, and the body is bent. In this part, a panel with a bending structure is proposed (see, for example, Japanese Patent Application Laid-Open No. 5-27514). According to the proposed panel, since the heat dissipating body is not deposited on the gas part for removing the conduit or the electric wire, not only the heat dissipation effect of the entire floor heating panel is reduced, but also the conduit or electric wire which is separated from the groove is pressed into the overlapping gas. And defects that can cause bending, breakage, and disconnection.

On the other hand, in a snowy area, there are several tens of centimeters of snow in one night, and if the snow accumulated on the roof of the house is left, the roof may not fall due to the weight of the snow. I needed to sweep my eyes. Since sweeping snow is heavy labor, a technique for dissolving snow accumulated on a roof by installing a heat sink or a heating plate on a roof of a house has recently been proposed, and has been put into practical use. However, the heat radiator or the heating plate, which is a product, is heavy and difficult to handle, and there is a drawback such as difficulty in construction because the product cannot be folded properly.

The inventors of the present invention have proposed a heat dissipating element that can be used for floor heating, snow melting, etc. without the above-mentioned defects (Japanese Patent Laid-Open No. 10-89712). However, since the heat dissipation body bends the heat dissipation body consisting of a plurality of elongate gases at the longitudinal end portion of the elongate gas, the parts are separated from the heat dissipation body of the body, and the parts removed at the time of construction of the heat dissipation body are removed. It is not undeniable that the work is complicated due to the need of placing (returning) the conduit or electric wire which is removed at the original position of the wire and bent in the hollow part or groove when it is bent. , Defects such as bending, breakage, and disconnection of wires, conduits, and wires cannot be completely eliminated.

This invention aims at the following.

(1) To provide a heat sink that can be wound at a light weight as a whole and is easy to handle, even though the surface is hard.

(2) Providing a heat sink that can be wound, but which is hard to twist, break or break in conduits or wires when wound.

(3) To provide a heat sink with high heat dissipation effect and simple construction work

(4) To provide a heat sink that is hard to be twisted even after long use

(5) To provide a method for installing the heat sink

In order to solve the above problems, in the flat heat dissipation body which can be wound, a plurality of elongated plate-shaped column-shaped bodies having hollows or grooves formed on one surface thereof are arranged adjacent to each other, and the hollow portions of the column-shaped gases are arranged in a plane. Alternatively, a heating device is embedded in the groove, and the flexible heat sink is attached to one side of the plurality of pillar-shaped gases so as to be integrally connected.

In the installation of the heat-sink which can be wound more and more, a plurality of elongated plate-shaped pillar-shaped gases having hollow portions or grooves are arranged adjacent to each other in a planar manner, and heating devices are embedded in the hollow portions or grooves of the pillar-shaped gases. Provided is a method of installing a heat-radiating heat sink, characterized in that the heat dissipation body which is integrally connected to one side of a plurality of columnar bodies by a flexible thin plate is installed on the bottom face of the heating device.

Hereinafter, the present invention will be described in detail.

In the columnar body constituting the heat dissipating body according to the present invention, a cut surface (hereinafter sometimes referred to simply as a "cut surface") cut in a direction perpendicular to a long longitudinal direction exhibits a substantially quadrangular shape. The fact that the cut surface exhibits a substantially quadrangular shape means that it may not be strictly a quadrangular shape, and it means that it includes what is deformed into a rectangular or trapezoidal shape. The pillar-shaped gas needs to have a hollow portion or a groove formed along the longitudinal direction. The hollow portion or groove formed by the pillar-shaped gas is to reduce the weight of the heat sink and to complete the function of embedding the heating device selected from the conduit or the electric wire.

The hollow part or groove formed along the longitudinal direction of the columnar body is not limited to one per columnar shape, but may be formed in plural. For example, when the cut surface is a rectangular quadrangular shape, two to seven hollow portions or grooves may be formed per one pillar. The pillar-shaped body may be formed integrally with the whole, but the cutting surface when cut in the direction perpendicular to the longitudinal direction has a U-shape, or a comb-shaped structure in which 1 to 3 teeth are installed on the cutting face of the U-shape. The hollow sections may be formed by combining the cut-off surfaces with the parts blocking the openings in the U-shaped or comb-shaped openings. Furthermore, in the shape of a comb, not everyone has the same height. In order to reduce the weight, the column-shaped gas may be a double walled U-shape.

The cross-sectional shape in the case where the hollow portion or the groove is cut at right angles in the continuous direction does not have to be the same as that of the column-shaped gas, and may be a quadrilateral or a U-shape. In the case of forming a plurality of hollow portions per one pillar-shaped gas, all hollow portions or grooves do not have to have the same shape, the same depth and the same width, and may be various combinations of changing the shape, depth and width of the hollow portion. have. In particular, it is preferable that the grooves in which the wires are embedded are narrower and shallower than other grooves.

The length and thickness of the column-shaped gas depends on the use of the column-shaped gas and the material to be composed, but the length is 100 cm to 400 cm and the thickness is a thickness for embedding a heating device selected from a conduit or an electric wire in a hollow part or a groove, for example. For example, it can select in the range of 20 mm or less. The depth of the hollow portion or the groove may be a space in which a conduit or an electric wire can be embedded, and the opening is preferably blocked by a part having a hollow portion for the purpose of reducing the extra space formed on the back of the electric wire. The thickness of the outer wall, partition wall, or groove forming the adjacent hollow portion should be sufficient to support the upper and lower wall surfaces of the columnar gas, and the thinner one is preferable because the weight reduction is achieved.

The material constituting the pillar-shaped gas having the hollow portion is selected from synthetic resin sheets, hard rubber sheets, wood plate shapes, metal plates or gypsum boards depending on the use of the heat dissipation body. For example, when the use of the heat sink is for floor heating, any of the above materials may be used. When the use of the heat sink is used for ceiling as a melting snow, a gypsum board is preferable from the viewpoint of fire resistance, and as a melting snow thereon. In the case of use, a hard rubber sheet is preferable from the viewpoint of waterproofing, and a synthetic resin sheet wooden board is preferred from the viewpoint of the load resistance.

The synthetic resin as a material constituting the columnar gas may be either a thermoplastic synthetic resin or a thermosetting synthetic resin, and may be a foam or a non-foamed foam. Specifically, foams having high rigidity such as crosslinked rubber foams and thermosetting resin foams, noncrosslinked polyethylene, noncrosslinked rubber foams, foams of a mixture of high density polyethylene and polystyrene, and the like are listed. The wood may be plywood, and examples of the metal include iron and aluminum. Among them, wooden board-like bodies and foams of thermoplastic synthetic resins are suitably applied in view of weight, groove workability and the like.

Where the columnar body consists of synthetic resin or hard rubber, the whole columnar body is integrally formed, the cut surface is U-shaped, double-walled quadrilateral, parts of one to three comb teeth, or parts thereof And parts for blocking the openings thereof can be produced by extrusion molding. In the case where the columnar body is made of wood or gypsum, a groove may be formed on one side of the quadrangular columnar body in the longitudinal direction, and in other words, it may be combined with a plastic part that blocks the opening of the groove. In the case where the pillar-shaped gas is made of metal, a part having a U-shaped cut surface may be manufactured by die casting, rolling, or the like, that is, it may be combined with a plastic part that closes the opening.

The heat dissipating body according to the present invention is arranged in such a manner that a plurality of pillar-shaped bodies having the hollow portions or grooves are adjacent to each other, for example, having a size of 400 cm x 200 cm, and a conduit or an electric wire at a suitable place of the hollow portions of these pillar-shaped bodies. Embed the selected heating device. In the case where a plurality of hollow portions are formed in the column-shaped gas, the size (thickness and width) of the column-shaped gas depends on the size of the column-shaped gas, but it is not necessary to embed the electric wires in all the hollow portions or the grooves. It is preferable to bury one to one in the hollow or groove of the shaped body. One conduit or electric wire is buried in one radiator, and in this case, a gap in which the conduit or electric wire can be inserted is formed in the side wall surface of the bulkhead groove of the hollow, and the conduits are formed at both ends of the column-shaped gas. Or it is preferable to arrange | position so that an electric wire may not cross.

The heat dissipating body according to the present invention bends the hollow part or the groove provided in the columnar body at both ends in the longitudinal direction, and communicates with the hollow part or the groove of the adjacent columnar body. And the hollow part of the curved part (actually formed to be substantially perpendicular to the edge part of the longitudinal direction of a columnar body) in the longitudinal direction both ends and the hollow part of the columnar gas which adjoins mutually, or the groove | channel. Or it is preferable to make a groove deeper and wider than the other hollow part or groove provided along the longitudinal direction of a columnar body. The range of depth and range can be changed by the structure of the column-shaped gas, the width of the hollow part or groove, the type of the conduit or the wire being embedded, the diameter thereof, etc., but may be selected within the range of less than 5 mm, especially 1 to 2 mm. There is a number. By extending the length and width of the hollow portion or groove of the curved portion deeper than other hollow portions or grooves at the same time, the range in which the conduit or electric wire can move in the hollow portion or groove increases, so that the conduit or Buckling, breakage, disconnection, etc., do not occur in the electric wire.

The heat dissipation body which concerns on this invention arrange | positions several pillar-shaped gas which has the said hollow part, mutually adjacent, and is comprised by bonding a flexible thin plate to one side, and integrally connecting. The flexible thin plate forms a continuous surface when the heat sink is wound in a roll shape, and serves as a surface or a back surface of the heat sink and acts as a heat conductor or heat reflector. Examples of the material of the flexible thin plate include nonwoven fabrics, woven fabrics, thermoplastic resin films, thermoplastic resin foam films, thermoplastic resin sheets, and combinations thereof. The kind of plastic thin plate can be suitably selected in consideration of the material of a heat sink, the use of a heat sink, the performance (noise, elasticity) of a required heat sink, etc.

In order to bond a flexible thin plate to one side of a plurality of columnar gases, it is preferable to apply the adhesive to one side of the flexible thin plate and to adhere the columnar gas to the surface on which the pressure-sensitive adhesive is applied. . In this case, the pressure-sensitive adhesive which can be used is preferably selected from among those which increase the adhesion between the column-shaped gas and the soluble thin plate, which is difficult to deteriorate by heat, and which are durable.

When the column-shaped gas is made of materials with low thermal conductivity, such as synthetic resin sheets, hard rubber sheets, gypsum boards, and upper parts of wooden boards, a combination of a material having high thermal conductivity with a flexible thin plate may improve the heat dissipation effect of the heat sink. There is a number. For example, in the case of a columnar body whose columnar body is formed of a synthetic resin sheet or a wooden board, having a U-shaped groove, the laminated body of the thermoplastic resin sheet / laminated nonwoven fabric, aluminum It is preferable that the laminate of the evaporation thermoplastic resin film / thermoplastic resin sheet, the laminate of aluminum evaporation thermoplastic resin film / nonwoven fabric / thermoplastic resin sheet, etc. are adhered to each other to form the back side of the heat dissipating body and reflect the heat to the surface side (upper side). . In the case where the pillar-shaped gas is made of metal, the cut surface blocks the opening of the U-shaped part with a synthetic resin part, and this film is a back surface of the heat sink by attaching a nonwoven fabric or a woven fabric to the surface of the synthetic resin part. It is preferable that the cut surface is printed on the back surface of the U-shaped pillar-shaped body (the surface opposite to the opening) to print a grain of wood or other various shapes to form the surface of the heat sink.

The heating fluid conduit constituting the heating device is preferably a crosslinked polyethylene pipe, a polybutene pipe, or the like, and its diameter can be appropriately selected depending on the use, the use region, and the like. The heating wire constituting the heating device is not preferable because the heat generation amount when the current is weak is not dangerous because the temperature does not rise to an appropriate temperature, and if the heat generation amount is strong, the temperature becomes excessively high. As the electric wires of the same kind as those used in ordinary electric plates, electric melting furnaces, and the like, electric wires that generate heat at a maximum temperature of about 30 ° C when an electric current of 100 volts introduced into a general household are energized are preferable.

The heat dissipating body according to the present invention has a plurality of columnar gases arranged in a predetermined direction, one side is bonded to the flexible thin plate, and the other side is an open planar structure in which the flexible thin plate is not bonded. have. It is preferable that a heat sink is a wooden board shape, and when the use is for floor heating, the other surface is coat | covered with a moisture-permeable film. The heat sink can be wound with the flexible sheet surface inward when it is manufactured, packaged, stored, stored and transported (see FIG. 3 to be described later). Since the conduit or electric wire is buried in the hollow or groove over a plurality of columnar gases, the range in which the columnar gases can move is restricted, and the flexible thin plate surface is hardly damaged when the flexible sheet surface is wound inward. . The hollow portion or groove is curved at the end side in the longitudinal direction of the column-shaped gas, and is made deeper and wider than the hollow portion or other portion of the groove, so that the conduit or electric wire has freedom in movement therein. Or the electric wires are not pushed out of the hollow portion or the grooves, and therefore, are not exposed, entangled, twisted, broken, or disconnected.

The heat dissipating body according to the present invention can be used as a floor heating panel, or as a ceiling plate, a roofing body of a roofing material, or the like installed on a base board of a wooden house, on a slab bottom surface, or on a base board of a slab floor surface. When installed at these locations, the radiator wound in a roll shape is rewound and installed at a predetermined place, and the end of the conduit is connected to the end of the heat transfer tube, or the end of the electric wire is 100 volts introduced into a general household. Just connect it to a power source. After installing the heat sink in a predetermined place, a nail may be fixed in a hole which is previously drilled in a place where a conduit or an electric wire is not buried to fix the foundation firmly.
