[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat radiator that can be wound. In more detail, it is used for floor heating and snow melting, and it can be wound despite its hard surface, packing, storage,
The present invention relates to a radiator that is easy to transport and lay.

2. Description of the Related Art Conventionally, 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 livability of a house in a cold region and the livability of a house in a warm region in a cold season. . For example, in single-family homes, the method of incorporating floor heating panels between the daiki and the floorboard, or on the underlying plywood laid on the daiki, has been adopted. A method of laying a floor heating panel directly on a slab floor or on a base plywood laid on the slab floor is adopted.

[0003] The floor heating panel is, for example, a long plate-shaped molded article made of foamed resin as a base, a groove is cut in one surface of the long plate-shaped base, and a tube for a heating fluid is embedded in the groove. do it,
A structure in which the surface is covered with a surface material such as an aluminum foil has also been proposed. In addition, a hard material such as a hard resin foam is used as a base, and a groove is formed on one surface of the base,
A structure in which a tube for a heating fluid is buried in the groove and the surface thereof is covered with a surface covering material such as an aluminum foil has been proposed. In order to construct a floor heating panel with such a structure, a factory first installs a floor heating panel in which a tube for heating fluid is arranged in a groove formed on one side of a long plate-shaped molded article made of foamed resin. The method of preparing and laying this at the laying site is adopted.

[0004] The floor heating panel can be selected and combined according to the size of the installation location, for example, in a length and width of 300 cm x 400 cm.
Items with a length of 0 cm or more are adjusted to at least 200 cm in length and width from the viewpoints of packing, transportation, storage, workability, etc., folded in the length or width direction, transported to the construction site, and folded It is laid open. However, there are drawbacks such as the surface after laying is soft, and the nail has no holding power when fixed by nailing.

[0005] When the floor heating panel on which the heating fluid tubes are arranged is folded, when the panel is simply folded as it is,
Conventionally, since the tube portion is crushed (buckled) or broken, a part of the conduit tube is conventionally inserted from the groove near the long base folded portion with the folded portion of the wide floor heating panel interposed therebetween. There has been proposed a panel having a structure in which the base is removed and the base is folded at the folded portion (for example, see Japanese Utility Model Laid-Open No. 5-27514). According to the panel of this proposal, since the radiator is not attached to the base portion from which the conduit is removed, not only the radiation effect of the entire floor heating panel is reduced, but also the conduit removed from the groove is folded. Pressed between the substrates
There was a disadvantage of being crushed.

Further, in a heavy snowfall area, there is a snow cover of several tens of centimeters overnight, and if the snow piled on the roof of a house is left untouched, the roof is crushed by the weight of the snow, so that the amount of snowfall is reduced. When it reached a certain level, it was necessary to remove the snow. Since this snow removal is heavy labor, a technique for dissolving the snow accumulated on the roof by installing a heat radiator or a heating plate on the roof of a house has recently been proposed and partially put into practical use. But,
The heat radiator or the heat generating plate, which is a product, is heavy and is difficult to handle, and the product cannot be bent properly, so that it is difficult to construct.

[0007]

Under such circumstances, the present inventors have tried to eliminate the drawbacks of the conventional method and to provide a radiator usable for floor heating, snow melting, and the like.
As a result of intensive studies, the present invention has been completed. The present invention aims at the following. 1. To provide a heat radiator that is lightweight as a whole, can be wound, and is easy to handle, despite its hard surface. 2. To provide a radiator that can be folded, but is less likely to buckle or break the heat medium flow tube when folded. 3. To provide a heat radiator having a high heat radiation effect. 4. To provide a radiator that is easy to perform.

[0008]

In order to solve the above-mentioned problems, the present invention provides a flat plate-shaped radiator capable of being wound.
The cut surface when cut in a direction perpendicular to the length direction has a substantially square shape, and a plurality of long pillars having a hollow portion or a groove formed are arranged adjacent to each other, and the hollow portion of the pillar Alternatively, a heat medium flow tube is embedded in the groove, and a flexible thin plate is attached to one surface of the plurality of columnar bodies and integrally connected to each other. Provide a radiator.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The columnar body constituting the heat dissipating body according to the present invention has a substantially rectangular cut surface (this cut surface may be simply referred to as “cut surface” hereinafter) cut in a direction perpendicular to the length direction. It has a shape. The expression that the cut surface has a substantially quadrangular shape means that the cut surface does not have to be strictly a square shape, and includes a shape that is deformed into a rectangular shape or a trapezoidal shape.
The columnar body needs to have a hollow portion or a groove formed along the length direction. The hollow portion or the groove formed in the columnar body has a function of reducing the weight of the heat radiator and embedding a heat medium distribution tube (hereinafter sometimes simply referred to as a “heat medium tube”).

The number of hollow portions or grooves formed along the length of the column is not limited to one per column, and a plurality of hollows or grooves may be formed. For example, when the cut surface is rectangular, two to five hollow portions or grooves can be formed per column. The pillars are
The whole may be integrally formed, but the cut surface when cut in a direction perpendicular to the length direction is made into a U shape, or in a U-shaped cut surface A comb-shaped structure provided with one to three teeth, the cut surface of which is formed by combining a U-shaped or comb-shaped opening with a part closing the opening, and forming a hollow portion. Is also good. In the case of a comb, all of the teeth need not have the same height (length). In order to reduce the weight, the columnar body may have a cut surface having a double-walled concave shape.

The cut surface of the hollow portion or groove does not need to be similar to the columnar body, but may be square, U-shaped, or the like. When forming a plurality of hollows per column,
It is not necessary that all the hollow portions or grooves have the same shape, and they may be combined with different shapes.

The length and thickness of the column depend on the use of the column, the material constituting the column, and the like, but the length is 100 cm or more.
The thickness of 400 cm can be selected within a range in which the heat medium tube can be embedded in the hollow portion or the groove, for example, in a range of 20 mm or less. The depth of the hollow portion or the groove may be any as long as there is a space in which the tube for the heat medium can be buried, and the extra space is preferably small. An outer wall that partitions an adjacent hollow part,
The thickness of the wall forming the partition wall or the groove only needs to be strong enough to support the upper and lower wall surfaces of the columnar body, and a thinner wall is preferable because the weight can be reduced.

The material constituting the columnar body having the hollow portion is selected from synthetic resin, hard rubber, wood, metal, gypsum and the like according to the use of the heat radiator. For example, when the use of the radiator is for floor heating, any of the above materials may be used, and when the use of the radiator is for snow melting and used for a ceiling, a gypsum board is preferable from the viewpoint of fire resistance, Further, when used for snow melting, it is preferable to select a material according to the purpose of use of the radiator, such as a hard rubber is preferable from the viewpoint of waterproofing and a synthetic resin is preferable from the viewpoint of load resistance.

The synthetic resin as a material constituting the columnar body may be either a thermoplastic synthetic resin or a thermosetting synthetic resin, and may be a foam or a non-foam. In particular,
Highly rigid foams such as crosslinked rubber foams and thermosetting resin foams, non-crosslinked polyethylene, non-crosslinked rubber foams, foams of a mixture of high-density polyethylene and polystyrene, and the like are included. The wood may be plywood, and examples of the metal include iron and aluminum.

When the column is made of synthetic resin or hard rubber, the entire column is integrally formed, the cut surface is a U-shape, a double-walled concave shape, and one or three teeth. And the like, or these parts and the parts that close the openings thereof, can be manufactured by an extrusion molding method. When the column is made of wood or gypsum, a cut surface may be provided with a groove along one of the sides of the rectangular column along the length direction, and if necessary, a plastic made to cover the opening of the groove. May be combined with the above components. When the columnar body is made of a metal, a part having a U-shaped cut surface may be manufactured by a die casting method, a rolling method, or the like, and if necessary, a part made of plastic may be combined with the opening part.

The radiator according to the present invention has a plurality of columns each having the above-mentioned hollow portion or groove arranged side by side, and has a size of, for example, 400 cm × 200 cm. Embed the medium tube. When a plurality of hollow portions are formed in the columnar body, it is not necessary to embed the heat medium tube in all the hollow portions or grooves, although it depends on the size (thickness, width) of the columnar body. Usually, it is preferable to bury one or every other in the hollow portion or groove of one columnar body. In one (one) heat radiator, one heat medium tube is embedded in a meandering manner, and at this time, a gap for inserting the heat medium tube is formed in the hollow partition wall and the side wall surface of the groove. It is preferable to arrange the heat medium tubes so that they do not cross each other at both ends of the columnar body.

The heat radiator according to the present invention is constituted by arranging a plurality of columnar bodies having the above-mentioned hollow portions so as to be adjacent to each other, attaching a flexible thin plate to one surface, and integrally connecting them. is there. The flexible thin plate forms a continuous surface when the heat radiator is wound in a roll shape, and serves as a front surface or a back surface of the heat radiator, and functions as a heat conductor or a heat reflection plate. Examples of the flexible thin plate include an aluminum foil, a tin foil, a stainless steel foil, a nonwoven fabric, a woven fabric, a thermoplastic resin film, a thermoplastic resin foam film, a thermoplastic resin sheet, and a combination thereof. The type of the flexible thin plate depends on the material of the radiator, the application of the radiator, and the performance (silence reduction,
Elasticity) can be selected as appropriate.

In order to attach a flexible thin plate to one surface of a plurality of columnar bodies, an adhesive is applied to one surface of the flexible thin plate, and a columnar body is applied to the surface to which the adhesive has been applied. It is preferable to use a method of bonding the body. The pressure-sensitive adhesive that can be used at this time is preferably one that increases the adhesive strength between the columnar body and the flexible thin plate, is hardly deteriorated by heat, and has durability.

When the columnar body is made of a material having a low thermal conductivity such as synthetic resin, hard rubber, gypsum board, wood, etc., when a material having a high thermal conductivity is combined with a flexible thin plate, a heat radiator is formed. Can improve the heat radiation effect. For example, in a case where the columnar body is a synthetic resin and the cut surface made of wood is a columnar body having a U-shaped groove, a laminate of aluminum foil / nonwoven fabric and a laminate of aluminum foil / thermoplastic resin sheet are provided on the opening side of the groove. It is preferable to adhere a body, a laminate of aluminum foil / nonwoven fabric / thermoplastic resin sheet, etc., and reflect the heat to the front side (upper side) as the back side of the radiator. If the columnar body is made of metal, the opening of the U-shaped part is closed with a synthetic resin part, and a nonwoven fabric, woven cloth, etc. is attached to the closed synthetic resin part for heat dissipation. It is preferable to print a wood grain pattern or other various patterns on the back surface (the surface opposite to the opening) of the columnar body having a U-shaped cut surface as the front surface of the heat radiator.

The tube for the heat medium is not particularly limited. For example, the tube is made of a cross-linked polyethylene tube, a polybutene tube, or the like.
The diameter varies depending on the location of the building on which floor heating panels and snow melting panels are installed, the thickness of the radiator, the type of heating fluid, the temperature, etc., but usually the outer diameter is 5 to 15 mm and the inner diameter is 3 mm. Tubing in the range of １２12 mm is common. Examples of the heat medium passed through the heat medium tube include hot water, steam, and heated oil.

The heat radiator according to the present invention has a plurality of pillars aligned in a predetermined direction, one surface of which is bonded to a flexible thin plate, and the other surface of which has no flexible thin plate bonded thereto. It has a planar structure. When manufacturing, packing, storing, storing, and transporting the radiator, the radiator may be wound in a direction perpendicular to the direction in which the columnar body extends, with the surface of the flexible thin plate inside. Yes (see Figure 2 below). Since the heat medium tube is arranged inside the hollow portion or the groove of the columnar body, it is not exposed (see FIG. 1 described later).
At the ends of the columnar body, they are arranged so as not to intersect with the gaps formed in the partition walls of the hollow portion and the side wall surfaces of the grooves (see FIG. 3 to be described later). , Do not entangle. Since the heat medium tube is buried across a plurality of pillars, the range in which the pillars can move is limited, and the surface of the flexible thin plate is wound when the flexible thin plate is wound inside. Hard to break.

The radiator according to the present invention is used as a base for a wooden house, on a slab floor, on a base plywood laid on a slab floor, on a ceiling plate, or as a base for roof material. be able to. When laying in these places, the heat radiator wound in a roll shape may be unwound and spread and laid in a predetermined place, and the end of the heat medium tube may be connected to the heat medium main tube. . After laying the heat radiator in place,
It may be fixed to the base by nailing or the like in a hole previously drilled in a place where the heat medium tube is not embedded.
