Disclosure of the invention

To be solved by the invention issues

Since the plastic radiator of the conventional example 1 ( 9 ) through a wall in the interior of the flat radiator body 100 forms multiple hot water paths, this can be easily produced, the thermal conductivity of the heat of the hot water in the direction of the outside air is low, since the radiation only from the outer wall surface 100 the group of parallel waterways 102 is effected.

Because heating by hot water towards the outer wall surface 108 from the water inlet 103 to the hot water outlet 104 is effected, the heating is carried out only by a reciprocating movement from one end to the other end of the radiator body, whereby a hot water supply section and a hot water Rückfuhrabschnitt the wall 108 the outer surface in their temperature differ.

While The radiator for an arrangement under a carpet or attachment to a wall surface is he is impaired in his picture as a heater be.

Further is, because the radiator is made of a plastic, a degradation by Ultraviolet light enter.

As the hot water way 102 in reciprocal form, the water resistance inside the path is large.

In the radiator of the conventional example 2 ( 10 ), the pipes P are arranged laterally so that their water resistance is large. In the case where the number of tubes is large, each tube forms a biased current, so the temperature of the radiation section passing through the flow path 201 is trained to make unequal.

Since there are many melting points, like the melting plate 203 , the pedestal 202 , a closing plate 204 and a group of tubes P, manufacturing is difficult and requires professionalism in the manufacturing process.

Further occurs degradation by ultraviolet light in the plastic pipes on.

The The present invention has been developed around the problems of common To dissolve or improve plastic radiators and order to cause a breakthrough in plastic radiators, which in their aesthetic Appearance and superior in thermal efficiency are.

Means for releasing the problems

The Heißwasserzirkiersradiator according to the invention forms, such as in 3 shown an exposed radiation section 8th from, the two hot water circulating radiation panels 81 . 82 , which consist entirely of a plastic resin, wherein the hot water circulating radiation panels 81 . 82 each one group of a plurality of vertically extending plastic pipes 8B have the same diameter and their length are equal to each other and are arranged parallel to each other, wherein the respective upper ends of the vertically extending plastic pipes 8B communicate with their respective lower ends by horizontally extending plastic pipes 8A and wherein the horizontally extending plastic tube 8A at the lower end with a hot water inlet 8S and a hot water outlet 8R is provided. and a frame (F) at the radiation portion 8th added from an upper bar 13 for closing the horizontal pipes 8A at the top, a bottom bar 15 for closing the horizontal pipes 8A at the lower end, a lateral bar 15 on the right and on the left side, an upper connector 16 to connect the top bar 13 with the lateral groin 15 and a bottom connector 17 to connect the bottom bar 14 with the lateral groin 15 consists.

In this case, the term "exposed" means the radiation panels 81 . 82 at least heat radiating panel surfaces, that is, the front and rear walls of a group of vertical tubes 8B are exposed to allow the radiating of heat that is distributed in the room.

Although the number of radiating panels 81 . 82 makes no difference, it should be noted that if a panel is provided, the hot water supply inlet 8S at the one end of the horizontal pipe 8A at the lower end and the hot water discharge outlet 8R at the other end of the horizontal tube 8A is disposed at the lower end while the vertical pipe 8B at the other end corresponding to the hot water discharge outlet 8R , a downwardly directed waterway via a closure plate which forms on the horizontal pipe 8A at the lower end before the hot water discharge outlet 8R is interposed so that the hot water supply inlet 8S and the hot water outlet 8R the radiator is located at the two ends of the radiation panels, which complicates the piping of the waterway.

If the number of radiation panels greater than three is, an intermediate radiation panel becomes the radiation efficiency reduce the radiant heat.

When the number of the radiation panels at the front and at the rear side is two, both the hot water supply inlet 8S as well as the hot water discharge outlet 8R at a position at one end of the horizontal pipe 8A may be disposed on the lower side so that the radiation panels can be easily connected to a hot water circulation system SY and the radiation efficiency of radiant heat from the radiation panel can be kept high. As a result, the number of radiation panels is typically two.

Next are both the horizontal tube 8A as well as the vertical tube 8B made of the same material and may be subjected to a commonly used heat fusion connection with each other and also the hot water supply inlet 8S as well as the hot water discharge outlet 8R can heat fusion with the horizontal pipe 8A be subjected using the same piece of pipe as in the horizontal tube 8A ,

In the radiator according to the present invention circulates since the radiation section 8th according to the present invention is a radiation panel, which is made by an exposed radiation panel consisting of a group of plastic pipes, a supply of hot water in the radiation panels to be heated 81 . 82 so that air surrounding the radiant panels is heated and warmed up while the radiant heat from the radiant panels 81 . 82 warmed up the space inside him. As a result, although the radiation panels 81 . 82 have a temperature to the extent that does not affect a human being when he or she uses the radiation panels 81 . 82 touched, a warming can be achieved, which is agreeable to the human body due to the sum of the warming, by a transmission and convection of air and a warming, which is achieved by radiant heat where is achieved by heating, which is safe and is delivered to a human body.

Next circulates at the radiation panels 81 . 82 , as these supplied hot water to these continues to rise and circulates simultaneously through the group of vertical tubes 8B that are short (standard: 400 mm) from the horizontal pipe 8A at the lower end towards the group of horizontal pipes 8A at the upper end, which are long (standard: 1520 mm), the circulating water circulates under a small resistance of the flowing water, whereby the entire surfaces of the radiant panels 81 . 82 for causing an air contact along the peripheral surface of each tube of the group of vertical tubes 8B to rise smoothly and uniformly so that a large heat transfer to the room air is achieved with a low resistance to a convective heat transfer.

In 2 is shown that the hot water circulating radiation panels 81 . 82 according to the present invention preferably are integral with each other such that the group of vertical tubes 8B each have a smaller diameter dB, which is between horizontal tubes 8A , each having a large diameter dA, at the upper and lower ends, while the respective vertical tubes 8B have a minimum distance gB to allow an increase and a flow of the heated air.

In this case, the horizontal pipes lead 8A at the upper and the lower end a holding function as well as a head function relative to the group of vertical tubes 8B and the vertical pipes 8B can be heated efficiently by this flowing hot water, making the horizontal pipe 8A typically has an outer diameter of 27 mm, a thickness of 5 mm, while the vertical tube 8B has an outer diameter of 13 mm and a thickness of 1.6 mm.

The rising air flow around the peripheral surfaces of the heated vertical tubes 8B behaves so that when the heated air, the vertical surface of each of the vertical tubes 8B 0.024 m / s, when spaced from the vertical surface by 5 mm, reaches 0.057 m / s when spaced from the vertical surface by 20 mm and produces a downward cold air, when it is 20 mm or more away from the vertical surface.

Priority will be the radiation amount of the radiation panels 81 . 82 Given as the vertical tube 8B the amount of radiation in the surface of the radiation panels increases as it is greater per unit area, and a gap is created at a position where the vertical pipe 8B with the horizontal pipe 8A is connected when the vertical pipe for connection to the horizontal pipe 8A fused, etc., so that the groups of vertical pipes 8B are preferably arranged parallel to each other. If the gap gB between the vertical tubes 8B 5 to 10 mm (standard: 7 mm) are the radiation panels 81 . 82 in their amount of radiation large, so that a forced flow of rising air on the peripheral surface of the vertical tubes 8B is produced.

Accordingly, the radiation panels cause 81 . 82 the stream of heated water, from the horizontal pipes 8A large diameter into a group of vertical pipes 8B to flow with a small diameter, whereby a heating surface is provided whose temperature difference is suppressed, while the surfaces of the group of vertical tubes 8B covering the radiation surfaces of the radiation panels 81 . 82 form a disturbance of the downward flow of cold air from above the respective vertical tubes 8B suppresses and further the presence of viscosity of the heated air between the vertical tubes 8B (Distance gB) suppressed, so that the heating of the ambient air → increasing effect (convective heat effect) of the group of vertical tubes 8B in the same way as a measured value can be achieved.

In In this case, the amount of radiation due to the convection per 1 m length 18.0 kcal / mh ° C for pipes of 13 mm in outside diameter, made of a PP-R plastic (polypropylene, Random, copolymer resin) while the amount of radiation due the radiation 7.68 kcal / mh ° C at a temperature of 80 ° C. on the side of the hot water inlet, 60 ° C on the side of the hot water outlet and 20 ° C as Room temperature is.

Accordingly, the radiation section creates 8th of the radiation panel, a gentle heating caused by the convection heating caused by the heated air in addition to the heating by radiant heat together with the conventional convection method, whereby a gentle warming occurs, which gives the human a feeling of warmth, without the room temperature is significantly increased.

Next are, as in the 2 and 3 shown the hot water circulating radiation panels 81 . 82 preferably integrated with each other by causing the first panel 81 that with the hot water supply inlet 8S on one side of the horizontal tube communicates at the lower end with the second panel which communicates with the hot water outlet 8R on one side of the horizontal tube 8A at the lower end through the communicating tube 8C at just the other end of the horizontal pipe 8A is discharged at the tube end, while the hot water circulating radiation panels 81 . 82 preferably are integral with each other for maintaining an interval gP between the opposed lateral surfaces of the first panels and the second panels for suppressing interference of the downflow of cold air from above and maintaining the gap gS between the horizontal tubes 8A at the top.

In this case, the first panels 81 and the second panel 82 , respectively through the horizontal pipe 8A are identical in length, and the vertical tubes 8B that are identical in length, with the integration of the first panels 81 and the second panel 82 can be formed by bonding, as in 3 is shown at both ends of the horizontal tube 8A at the lower end and one end (the right end) of the horizontal pipe 8A at the upper end via a spacer tube 8D and also connecting them to the other end (left end) of the horizontal tubes 8A at the top over the communication tube 8C in a continuous manner, while the vertical tube 8B at the left end of the second panel 82 the way down to the horizontal tube 8A at the lower end forms through the closure plate 8E of the horizontal pipe 8A at the top and the vertical tube 8B at the right end of the second radiation panel 82 forms a round directional path from the horizontal pipe 8A at the upper end through the closure plate 8E of the horizontal pipe 8A at the bottom.

The hot water route makes, as in 3 shown a circulation path in the interior of the radiation panels, wherein flowing water (f1) from a hot water supply inlet 8S at the (right) side of the radiant panels 81 is circulated at the lower end, is supplied, and sequentially horizontally flowing water (f2) inside the horizontal tube 8A at the lower end of the first radiation panel 81 → rising streaming water (f3) of the group of vertical pipes 8B the first radiation panel 81 → horizontally flowing water (f4) inside the horizontal tube 8A at the top of the first panel 81 → horizontally flowing water (f5) inside the communication tube 8C that from the first panels 81 with the second panel 82 communicates → downflowing water (f6) in I inside the vertical tube 8B at the left end of the second panel 82 → horizontally flowing water (f7) inside the horizontal tube 8A rising water (f8) of the vertical tubes rising from the right at the lower end of the second panels 8B the second panel → horizontally flowing water (f9) inside the horizontal tube 8A at the upper end of the second panel → water (f10) flowing down inside the vertical tube 8B at the right end of the second panel 82 → flowing water (f11) from the hot water discharge outlet 8R ,

Accordingly, in the group of vertical pipes 8B , the radiation surfaces within the first radiation panel 81 and the second radiation panel 82 simultaneously heated by the uniformly flowing water from the horizontal pipe 8A at the lower end to the horizontal pipe 8A at the upper end, leaving the first radiation panel 81 and the second radiation panel 82 Form heating surfaces that have no unevenness in the heating temperature.

Since the distance gP between opposite lateral surfaces of the first panel 81 and the second panel 82 a distance gP is (default: 18.5 mm) which is determined under the condition that there is a distance between the horizontal pipe 8A at the top of the first panel and the horizontal tube 8A remains at the upper end of the second panel and under the condition that the distance gP is a distance sufficient for suppressing a disturbance of the downward flow of cold air from above, namely not more than 40 mm apart, the rising of the heated air alone is generated between the first panel 81 and the second panel 82 , whereby the air, which is the radiation section 8th surrounds, circulates and, as a result, creates the following cycle: unheated air → heated air → gentle rise of air.

The first circulation radiation panel 81 and the second circulation radiating panel 82 thus cooperate to provide a heat surface with no inequality in the heating temperature and a large amount of radiation, and also cause heating caused by gentle natural convection by the heating and gentle rise of surrounding indoor air.

At the radiation section 8th According to the present invention it is preferred that all tubes 8A . 8B the radiation panels 81 . 82 consist of two-layer molded plastic pipes, which are provided with a coating layer on its surface.

In this case, where the horizontal pipe 8A and the vertical tube 8B formed on PP-R resin, plastic for the surface layer can be formed by a two-layer extrusion by mixing a pigment of the same resin as the PP-R resin for the internal tubular body, whereby a surface layer of 0.4 to 0.5 mm in its thickness is formed.

Accordingly, the radiation panels 81 . 82 in a desired color, thereby forming a radiator which is good in appearance and can be suitably placed in a room.

Although the respective tubes 8A . 8B of the existing plastic radiation section 8th pigment having been colored with desired colors, pigment is not supplied to the tube body of the inner layer, so that a reduction in durability by the mixing of pigment to the tubes 8A . 8B can be avoided.

As in 1 it is further preferred to provide a frame F at the radiation section 8th to provide, wherein the frame F is an upper bar 13 to hide the horizontal tube 8A at the top, a bottom bar 14 to hide the horizontal tube 8A at the bottom, sidebars 15 on the right and the left side, an upper connector 16 to connect the top bar 13 with the lateral groin 15 and a bottom connector 17 to connect the bottom bar 14 with the lateral groin 15 ,

In this case, it is sufficient, the top bar 13 with air holes, etc., whereby an air flow from the lower surface to the upper surface of the radiation section 8th is ensured.

Invisible sections like an uneven shape of the rounded corners at the junction, which are made by welding the group of vertical tubes 8B the radiation panels 81 . 82 with the horizontal pipe 8A and so on may be hidden, thereby concealing the appearance of the upper surface, side surfaces and so forth of the radiator through the frame F to ensure a favorable appearance.

Mounting a radiator HR on the wall surface and so on is facilitated by supporting the bottom rail 14 the radiator by using a lower mounting bracket 10B , which is provided separately in the form of an angle and insertion of an upper mounting bracket 10A for carrying the horizontal pipe 8A at the top in the lower part of the top bar 13 and so on, and also mounting the radiator HR, which does not interfere with the thermal expansion caused by the fact that the vertical tube 8B and the horizontal pipe 8A made of a plastic, can be used, carrying the radiation section 8th in a suspended state, allowing the radiation section 8th expanded in a horizontal direction and also carrying the lower end of the radiation section 8th through the lower bar 14 in the form of a free end around the radiation section 8th to allow to expand in a vertical direction.

The frame of the radiator according to the present invention preferably has, as in 5 shown the bottom bar 13 on that with a pressure part 13R towards the top of the horizontal tube 8A on both sides of the base plate 13B pointing down from the central part of the upper side 13T protrudes over the width, over a section 13A , an airflow bore H13 at the central part of the bottom plate and the pressure part 13R towards the horizontal pipe 8A on the inner surface of the lower end of the vertical side 13F on both sides of the top bar, with a top cover 18 with a group of air holes Ha evenly provided in this, in the cutout 13A the upper side 13T the top bar 13 are fitted to the cutout 13A close.

In this case, the top bar 13 , the bottom bar 14 and the top cover 18 designed to form a two-layered extrusion die and the outflow bore H13 of the upper bar 13 and the air holes Ha of the top cover may be formed by piercing in a further step. Because the neckline at the central part of the top bar 13 is covered in width with the upper cover, comes the Luftausströmbohrung H13 of the bottom plate 13B the top bar in a state where it is not visible from the outside. The shape and arrangement of the air outlet H13 of the top bar 13 are selectably selected in terms of operationality and cost under the condition of ensuring the passage of heated air from the lower portion to the upper portion of the radiation portion 8th , which then, if only the air holes Ha of the top cover 18 are arranged uniformly to improve the appearance, for example as in 5 (D) shown, the upper surface of the radiator, namely the top cover has a good appearance with uniform blowout of the heated air. Because the top cover is used and piercing through the bottom plate 13B under the neckline 13A the top bar 13 can be easily and inexpensively performed by selecting the shape and the arrangement of the Luftausströmbohrung H13.

In 5 (A) is shown that the top bar 13 with a curved pressure part 13R is provided, which is against the horizontal pipe 13 from the surface of which presses and the curved pressure part 13A against the horizontal pipe 8A from the lower part presses its side surface. The frame F is so uniform in the radiation section 8th fitted without play when the frame F in Radungsab cut 8th is fitted to be covered in this way.

Because the bottom bar with the lateral bar 15 on both sides through the lower connector 17 is integral, as in 2 Of course, he takes the lower end of the radiation body 8th on, so the horizontal tube at the lower end in a free-hanging form, an expansion deformation caused by thermal expansion of the group of vertical tubes 8B is caused, can thus be recorded without difficulty.

In the radiator according to the present invention, it is further preferable that the frame F has frame members made of plastic and provided with a coating layer on the surface thereof, and is detachable with the radiating portion 8th in one piece by fitting into the radiation section 8th ,

In this case, it is typically the same color as the color of the radiation panels 81 . 82 although the frame member is free in color and with a coating layer of 0.4 mm in thickness.

Even though each frame member of the frame F is a plastic molded product It is simple, every element as a detachable fit structure and it can be produced at low cost.

There the pigment is not in the inner part (base part) of the base element is mixed in, as in the typical two-layer extrusion molding the frame element is a degradation of the weather resistance caused by a Mixing caused by pigment, be avoided, though it is a colored plastic product.

Effect of the invention

According to the present invention, there is a group of vertical groups 8B arranged in parallel and made of plastic, the radiation section identical in diameter and communicating with the horizontal pipe 8A at its upper and lower ends, hot water flows uniformly from the horizontal pipe 8A , which performs the head function, into the group of respective pipes 8B so that the hot water circulating radiation panels of the radiation section 8th a uniform heating surface forms with no temperature inequality.

Since the hot water circulating radiation panels 81 . 82 are made of plastic, it is possible to obtain an interior heating that is comfortable for the human body by the sum of the heat caused by the convection of heated air and the heating that is achieved by the radiant heat, thereby heating is achieved, which is free of burns, even if the radiation panels 81 . 82 is touched by the hand of a human and is safe and pleasant for the human body.

[Radiant section 8th (Figure 3)]

A radiation section 8th circulates heated hot water, thereby causing surrounding indoor air to be guided, circulated and heated and radiate radiant heat emitted into a room and has two pieces of radiant panels 81 . 82 which are identical in size and arranged at the front and rear side. 3 (A) is a front view of a first radiation panel 81 . 3 (B) is a left side view of a radiation section 8th which is formed by integration of the first radiation panels 81 with the second radiation panel 82 . 3 (C) is a right side view of the radiation section 8th and 3 (D) is a front view of the second panels 82 ,

As in 3 shown are the first radiation panels 81 and the second radiation panel 82 with a group of vertical vertical tubes arranged vertically 8B , which are slim and identical in length, provided the vertical tubes 8B communicate with the horizontal pipe 8A , which is large in diameter, at its upper and lower sections.

The horizontal pipe 8A the radiation panels 81 . 82 has an outer diameter of 27 mm and a thickness of 5 mm, while the vertical tube 8B has an outer diameter of 13 mm and a thickness of 1.6 mm and these tubes 8A and 8B are made of polypropylene, random, copolymer resin (PP-R resin) and are made by a two-layer extrusion molding to form a coating on their surface which is 0.4 mm thick.

In this case, due to the coating on the surface, it is sufficient to mix a selected pigment with the PP-R resin so that the plastic pipes 8a . 8B show a desired color on the surface layer, thereby avoiding addition of pigment to the tube body and degradation due to weathering.

Although the lengths of the vertical tube 8B and the horizontal pipe 8A are suitably selected and determined depending on the property of the radiator HR, the radiator HR is used by a 3 kW electric hot water heating system with horizontal pipes 8A that have 1520 mm in length and a vertical tube 8B that has 400 mm in length, with a group of vertical tubes 8B is welded to the horizontal tube before joining such that a distance between the respective vertical tubes 8B 7 mm, resulting in communication of the vertical tube 8B with the horizontal pipe 8A is caused.
