Description

Technical field

The present invention relates to a radiator for circulating hot water for space heating and, more particularly, to a radiator comprising a group of pipes for circulating hot water made of polymer resin and operating as a radiating section open to the outside.

State of the art

A radiator having a radiating section for circulating hot water made of plastic is known from the known Example 1 according to FIG. 9 and Example 2 according to FIG. 10.

Known example 1 (Fig. 9) is a radiator for circulating hot water described in Patent Document 1 and shown in Fig. 9 (A) (front view with a partial cutaway), Fig. 9 (B) (top view with a partial cutaway) ) and Fig. 9 (C) (section).

In this radiator, the flat casing 100 is divided into two parts by a partition 101 extending in the direction of the thickness of the casing, thereby at the surface of one part in the longitudinal direction there passes a group of channels 102 for hot water, while a group of supply channels departs from the inlet 103 and to the outlet hole 104 fits a group of return channels. The channels are formed by a wall covering these groups of channels, so that hot water circulates through all the hot water channels 102 through the return manifold 105. Thus, the radiator is in the form of a flat plate made of plastic and provided with an external surface 108, one side of this external surface located in the second part, and the lower side 109 of the radiator is filled with heat insulating material 107. In this case, the radiator is installed on the floor surface or on the wall surface during use.

In addition, Example 2 (FIG. 10) is a radiator for circulating hot water, provided with a radiating section made of plastic pipes P, as described in Patent Document 2. FIG. 10 (A) illustrates a fluid passage 201 serving as a radiating a section formed by bending and laying one plastic pipe P. FIG. 10 (B) shows a plurality of pipes P arranged in parallel and communicating with each socket 202 at both ends to form a fluid channel 201. Hot water flows through a group including all pipes through each socket 202 at one end of the supply pipe SP, and enters the return pipe RP through each socket 202 at the other end. Figure 10 (C) schematically shows a group of pipes P, divided by sockets 202 into many subgroups, and hot water circulates through each subgroup of pipes. Figure 10 (C) schematically shows the direction of water flow in the nesting section, and figure 10 (D) shows the nesting section in perspective.

Problems Solved by the Invention

Since in the plastic radiator according to the known example 1 (Fig. 9), a plurality of hot water channels are formed by partitions located inside the flat body 100, it is easy to manufacture. However, the efficiency of thermal conductivity from hot water to the surrounding air is low, since radiation is carried out only by the surface 108 of the outer wall of the group of parallel channels 102 for water.

Further, since the surface of the outer wall 108 is heated with hot water when the hot water moves in only one direction, from the inlet 103 to the outlet 104, or from one end of the radiator to the other, the hot water supply section and the hot water return section on the outer surface walls 108 will have different temperatures.

Although such a radiator can be laid under a carpet or mounted on a wall surface, it is ugly as a heater.

In addition, since the radiator is made of plastic, it decomposes under the influence of ultraviolet radiation.

Further, since the hot water in the channel 102 moves in a reciprocating direction, it exhibits significant resistance to the movement of water.

In the radiator of Example 2 (FIG. 10), the pipes P are transverse and therefore exhibit significant resistance to the flow of water. If the number of pipes is large, each pipe P creates a biased flow, which leads to an uneven temperature distribution in the radiating section formed by the channel 201.

Further, since there are many welding points in such a radiator, for example, on a welded plate 203, on a socket 202, on a cover plate 204 and on a group of pipes P, this radiator is difficult to manufacture and requires skilled labor.

In addition, plastic pipes decompose under the influence of ultraviolet radiation.

The present invention was developed to solve or mitigate the above problems of known plastic radiators and to provide an improved plastic radiator with an improved design and high thermal efficiency.

Problem Solving Tools

A radiator for circulating hot water according to the present invention comprises, for example, as shown in FIG. 3, an external radiating section 8, comprising panels 81, 82 for circulating hot water, made up of tubes made entirely of polymer resin, each radiating panel 81, 82 for circulating hot water contains a group of plastic vertical pipes 8B, identical to each other in diameter and length and located in parallel. The upper ends of the vertical plastic pipes 8B communicate with the corresponding lower ends through the horizontal plastic pipes 8A. At the lower end of the horizontal plastic pipes 8A, there is an inlet 8S and an outlet 8R for hot water.

The radiating section 8 comprises a frame F comprising an upper frame member 13 hiding the upper horizontal tubes 8A, a lower frame member 14 hiding the lower horizontal tubes 8A, side frame members 15 on the right and left sides, upper connectors 16 for connecting the upper frame member 13 to side frame members 15 and lower connectors for connecting the lower frame member 14 to side frame members.

In this case, the term “open from the outside”, referring to the radiating panels 81, 82, means that at least the surfaces of the panels radiating heat, that is, the front and rear surfaces of the group of vertical tubes 8B, are open from the outside, which allows the radiated heat to dissipate throughout the room .

Further, although the number of radiating panels 81, 82 does not matter, if there is one panel, the hot water inlet 8S is located at one end of the lower horizontal pipe 8A, and the hot water outlet 8R is located at the other end of the lower horizontal pipe 8A, whereas the vertical pipe 8B at the other end corresponding to the hot water outlet 8R forms a downward channel passing through a cover plate mounted on the lower side of the horizontal pipe 8A in front of the outlet pipe 8R so that the inlet pipe 8S and the exhaust pipe 8R of the radiator are located at different ends of the radiating panel, which makes it difficult to route the pipes for hot water.

Further, if there are more than three radiating panels, the intermediate radiating panel will have a reduced heat emission efficiency.

In addition, if two radiating panels are used, one after the other, both the inlet pipe 8S and the outlet pipe 8R can be located at one end of the lower horizontal pipe 8A so that the radiating panels can be easily connected to the hot water circulation system SY, the heat emission efficiency of the radiating panel remains high. Therefore, two radiating panels are typically used.

In addition, both the horizontal pipes 8A and the vertical pipes 8B are made of the same material, and they can be joined by a common welding method. The inlet pipe 8S and the outlet pipe 8R can be welded to the horizontal pipes 8A in one section.

Accordingly, in the radiator of the present invention, since the radiating section 8 is a radiating panel formed by an external radiating panel formed by a group of plastic pipes, the supplied hot water circulates in the heated radiating panels 81, 82 so that the air surrounding the radiating panels is heated in while the radiated heat from the panels 81, 82 warms the room. As a result, although the temperature of the radiating panels 81, 82 is not so high as to injure a person when they are touched, they can provide gentle and comfortable heating by summing the heating carried out by convection of air and heating by heat radiation. The result is a safe and pleasant body heating.

Further, since in the radiating panels 81, 82, the supplied water rises and circulates immediately along the group of short vertical pipes 8B (standard length 400 mm), from the horizontal pipe 8A located below, to the group of long horizontal pipes 8A (standard length 1520 mm) located above, the circulating water encounters a low resistance, as a result, uniformly heating the entire surface of the radiating panels 81, 82. Therefore, the air in contact with the peripheral surface of each pipe of the group of vertical pipes 8B rises evenly smoothly, while achieving good heat transfer to the air in the room with a low resistance convection heat transfer.

As shown in FIG. 1, a frame F is added to the emitting section 8, which comprises an upper frame member 13 covering the upper horizontal tubes 8A, a lower frame member 14 covering the lower horizontal tubes 8A, side frame members 15 on the left and right sides, an upper connector 16 for connecting the upper frame member 13 to the side frame members 15, and a lower connector 17 for connecting the lower frame member 14 and the side frame members 15.

In this case, air holes should be made in the upper element 13, allowing air to pass from the lower surface to the upper surface of the radiating section 8.

Accordingly, the ugly parts, for example, the uneven shape of the rounded corner at the connection formed by welding a group of vertical pipes 8B of the radiating panels 81, 82 with horizontal pipes, etc., can be hidden, thereby improving the appearance of the upper, side and other surfaces of the radiator with a frame F.

Additionally, the installation of an HR radiator on a wall surface, etc. simplified by relying on the lower mounting bracket 10B, made separately in the form of a corner, and thanks to the upper mounting bracket 10A inserted into the lower frame member 13, which supports the upper horizontal pipes 8A, etc. The radiator HR can be installed so that there is no interference with its thermal expansion, taking into account the fact that the vertical pipes 8B and horizontal pipes 8A are made of plastic, i.e. the radiating section 8 can be suspended, which will allow it to expand in the horizontal direction, and to support the free lower end of the section 8 with the lower frame member 14 so that the radiating section 8 can expand in the vertical direction.

Further, as shown in FIG. 2, the radiating hot water circulation panels 81, 82 of the present invention are preferably integrated with each other such that a group of vertical tubes 8B of small diameter dB are located between horizontal pipes 8A of large diameter dA, at the upper and lower ends while the corresponding vertical pipes 8B are installed with a minimum interval gB, allowing only heated air to rise and flow.

In this case, the horizontal pipes 8A located at the upper and lower ends perform a holding function as well as a collector function for a group of vertical pipes 8B that are effectively heated by running hot water so that the horizontal pipe 8A typically has an outer diameter of 27 mm and a wall thickness of 5 mm, and the vertical pipe 8B has an external diameter of 13 mm and a wall thickness of 1.6 mm.

The rising air flow around the peripheral surfaces of the heated vertical pipes 8B has a lifting speed of 0.024 m / s at a distance of 5 mm from a vertical surface and 0.057 m / s at a distance of 20 mm from a vertical surface, and a downward flow of cold air occurs at a distance of 20 mm or more from a vertical surface.

Priority is given to the emission value of the emitting panels 81, 82, since the vertical pipes 8B increase the radiation on the surface of the emitting panel if there is a large specific area, if there is a gap in the position where the vertical pipe 8B is connected to the horizontal pipe 8A when the vertical pipe 8 is welded to the horizontal pipe 8A, etc., therefore, the vertical group pipes 8B preferably extend parallel to each other. Accordingly, if the gap gB between the vertical pipes 8B is 5-10 mm (standard 7 mm), the radiating panels 81, 82 are highly emitting, and the necessary upward air flow arises around the peripheral surfaces of the vertical pipes 8B.

Accordingly, in the radiating panels 81, 82, the incoming hot water flows from the horizontal pipes 8A of large diameter immediately into the group of vertical pipes 8B of small diameter, as a result of which there is no temperature difference on the heated surface. At the same time, the heated surfaces of the group of vertical pipes 8B, which form the radiating surfaces of the radiating panels 81, 82, can prevent the downward flow of cold air from above relative to the vertical pipes 8B and prevent the stagnation of heated air between the vertical pipes 8B (in the gap gB), therefore, heating circumferential air is equivalent to the lifting effect (convection heating effect) by a group of vertical pipes 8B and can be measured.

In this case, for example, pipes made of PP-R resin (polypropylene with an arbitrary copolymer) and having an external diameter of 13 mm, the amount of radiation due to the convection flow per 1 m of length is 18.0 kcal / mh ° C, while the amount of radiation through radiation is 7.68 kcal / mh ° C at an inlet water temperature of 80 ° C, an outlet water temperature of 60 ° C and an ambient temperature of 20 ° C.

Accordingly, the radiating section 9 of the radiating panel provides soft heating by combining convection heating of air and radiated heat, together with natural convection, which allows people to feel the heat without a significant increase in temperature in the room.

Further, as shown in FIGS. 2 and 3, the radiator panels 81, 82 for circulating hot water are preferably connected to each other so that the first panel 81, provided with an inlet pipe 8S on the lower side of one side end of the horizontal pipe 8A, communicates with the second panel 82, provided with an outlet pipe 8R on the lower side of one side end of the horizontal pipe 8A, through a connecting pipe 8C located on the upper side of the other end of the horizontal pipe 8A. The hot water radiating panels 81, 82 are preferably connected to each other while maintaining a gap gP between the opposite side surfaces of the first panel 81 and the second panel 82 to prevent cold air from entering from above, and maintaining a distance gS between the upper horizontal pipes 8A.

In this case, the first panel 81 and the second panel 82 are respectively formed by horizontal pipes 8A of the same length and vertical pipes of the same length, and the connection of the first panel 81 and the second panel 82 can be carried out, as shown in FIG. 3, at both ends of the lower horizontal pipes 8A, and at one end (right) of the upper horizontal pipes 8A through the intermediate pipe 8D, and at the other end (left) of the upper horizontal pipes through the connecting pipe 8C, creating a continuous channel. The vertical pipe 8B at the left end of the second panel 82 forms a downward channel leading to the lower horizontal pipe 8A, due to the jumper 8E in the upper horizontal pipe 8A, and the vertical pipe 8B at the right end of the second radiating panel 82 forms a downward channel from the upper horizontal pipe 8A, due to the jumper 8E in the lower horizontal pipe 8A.

The hot water motion path, as shown in FIG. 3, forms a circulation path inside the radiating panel, in which the water flow (f1) circulates from the hot water inlet 8S located on one (right) side of the bottom of the first radiating panel 81, and sequentially goes into a horizontal flow (f2) in the lower horizontal pipe 8A of the first radiating panel 81, then into an upward flow (f3) in the group of vertical pipes 8B of the first radiating panel 81, into a horizontal flow (f4) in the upper horizontal pipe 8A the first panel 81, into the horizontal flow (f5) in the connecting pipe connecting the first panel 81 to the second panel 82, into the downward flow (f6) in the vertical pipe 8B at the left end of the second panel 82, into the horizontal flow (f7) in the lower horizontal pipe 8A of the second panel 82, into the upward flow (f8) in the vertical pipes 8B of the second panel, into the horizontal flow (f9) in the upper horizontal pipe of the second panel, into the downward flow (f10) in the vertical pipe 8B at the right end of the second panel, and into the stream (f11) exiting the hot water outlet 8R.

Accordingly, the group of vertical pipes 8B forming the radiating surfaces in the first radiating panel 81 and in the second radiating panel 82 are heated simultaneously by uniformly flowing hot water from the lower horizontal pipe 8A to the upper horizontal pipe 8A so that the first radiating panel 81 and the second radiating panel 82 form radiating surfaces that do not have temperature differences.

In addition, since the spacing gP (standard 18.5 mm) between the opposite side surfaces of the first panel 81 and the second panel 82 is an interval due to the gap between the upper horizontal pipe 8A of the first panel 81 and the upper horizontal pipe 8A of the second panel 82, and should be sufficient to prevent a downward flow of cold air from above, i.e. should not exceed 40 mm, then between the first panel 81 and the second panel 82 there is only an upward flow of air, and the air circulating around the radiator section 8 sequentially becomes unheated air → heated air → smoothly rising air.

Accordingly, the first circulation radiating panel 81 and the second circulation radiating panel 82 interact with each other to form a heating surface that does not have irregularities in the heating temperature and creates strong radiation, and are able to heat the room, creating soft natural convection, heating and creating an upward flow of air into indoors.

Further, in the radiating section 8 of the present invention, all of the pipes 8A, 8B of the radiating panels 81, 82 are made of two-layer molded plastic pipes, the surface of which is coated.

In this case, when the horizontal pipe 8A and the vertical pipe 8B are molded from PP-R resin, plastic for the surface layer can be obtained by two-layer extrusion molding by mixing the pigment in the same PP-R resin that is used for the inside of the pipes, thereby getting a surface layer with a thickness of 0.4-0.5 mm

Accordingly, the radiating panels 81, 82 can be made in the desired color, obtaining a radiator with an attractive appearance and which can be installed in a room in a suitable place.

In addition, despite the fact that the corresponding pipes 8A, 8B of the plastic emitting section 8 have the desired color, no pigment is added to the inner layer of the body of the pipe to avoid reducing the durability that pigment can add to the pipes 8A, 8B.

Further, the radiator frame of the present invention preferably comprises, as shown in FIG. 5, the upper frame member 13 provided with an abutment 13R facing the upper side of the horizontal pipe 8A on both sides of the lower plate 13B, which is extended downward from the central portion 13T, oriented the width of the radiator and passes through the cutout 13A. An opening 13H is made in the central part of the plate 13B for passing the air flow, and on the inner surface of the lower side of the vertical wall 13F, there is an abutment 13R on both sides of the upper frame element, facing the horizontal pipe 8A, while the cutout 13A of the upper wall 13T of the upper frame element 13 the upper cover 18 is inserted with a group of air holes H evenly distributed over it, closing the cutout 13A.

In this case, the upper frame member 13, the lower frame member 14 and the upper cover 18 are formed by two-layer extrusion molding, and the air outlet H13 of the upper frame member 13 and the air holes on the upper cover 18 can be made by punching in a subsequent step. Since the cutout 13A in the central portion of the upper frame member 13, oriented in the width direction, is covered by the top cover, the air outlet H13 of the lower plate 13B of the upper frame member is visible from the outside.

The shape and location of the air outlet H13 of the upper frame member 13 are selected based on operability and cost considerations so as to ensure the passage of heated air from the lower part of the radiating section 8 to its upper part. If the air holes Ha in the upper cover 18 are evenly distributed, paying attention to the appearance, for example, as shown in FIG. 5 (D), the upper surface of the radiator, i.e. the top cover will have an attractive appearance and evenly remove heated air. By using the upper cover 18, the operation of perforating the lower plate 13B under the cutout 13A in the upper frame member 13 can be performed without difficulty and at high cost by selecting the shape and location of the outlet H13.

Then, as shown in FIG. 5 (A), since the upper frame member 13 is provided with a curved stop 13R that abuts against the upper surface of the horizontal pipes 8A and a curved stop 13R that abuts against the bottom of the side surfaces of the horizontal pipes 8A, the frame F is uniformly set on the radiating section 8 without gaps, closing it.

In addition, since the lower frame element is integrated with the side frame element 15 on both sides using the lower connector 17, as shown in FIG. 2, and in the lower frame element is located the lower part of the radiating section 8, namely, the freely suspended lower horizontal pipe 8A , deformations of a group of vertical pipes 8B arising from thermal expansion do not encounter any obstacles.

Further, in the radiator of the present invention, preferably, each element of the frame F is made of plastic and has a coating layer on the surface, with each element of the frame F removably attached to the radiating section 8.

In this case, although each frame element can have any color, they usually have a color corresponding to the color of the radiating panels 81, 82, and the coating layer has a thickness of 0.4 mm.

Accordingly, since each element of the frame F is a molded plastic part, such an element is easily fabricated as an inexpensive removable structure.

In addition, since during a typical two-layer extrusion molding, the pigment is not mixed into the inner part (base) of the part element, the degradation of the frame elements under the influence of the environment is prevented, although they are made of colored plastic.

Effect of the invention

According to the present invention, since the vertical pipes 8B of the radiating section 8, arranged in parallel and made of plastic, have the same diameter and communicate with the upper and lower horizontal pipes 8A, hot water flows evenly from the horizontal pipe 8A, which acts as a collector, into a group of vertical pipes 8B so that the surface of the radiating panel of section 8 for circulating hot water is heated evenly and has no temperature changes.

Since the plastic radiating panels 81, 82 for circulating hot water are open outside, the room can be heated so that a person experiences gentle and soft heat due to the sum of convection of heated air and the radiated heat, while such a safe and pleasant heating system is not a source of burns, even if a person touches the radiating panels 81, 82.

Description of preferred embodiments of the invention

[Radiating section, (FIG. 8)]

The radiating section 8 is designed to circulate hot water, resulting in convection and heating of the surrounding air in the room, while the heat is radiated into the room. The radiating section 8 consists of two radiating panels 81, 82, the same size and located one after the other. FIG. 3 (A) is a front view of the first radiating panel 81, and FIG. 3 (c) is a left view of the radiating section 8 formed by connecting the first radiating panel 81 to the second radiating panel 82. FIG. 3 (C) the right side of the radiating panel 8 is shown, and FIG. 3 (D) is a front view of the second panel 82.

As shown in FIG. 3, the first radiating panel 81 and the second radiating panel 82 comprise a group of parallel vertical thin tubes 8B having the same length, with the vertical tubes 8B communicating with their upper and lower ends to larger horizontal tubes 8A.

The horizontal pipes 8A of the radiating panels 81, 82 have an external diameter of 27 mm and a wall thickness of 5 mm, and the vertical pipes 8B have an external diameter of 13 mm and a wall thickness of 1.6 mm, while these pipes 8A, 8B are made of polypropylene with an arbitrary copolymer ( PP-R) by a two-layer extrusion molding method to create a coating layer with a thickness of 0.4 mm on their surface.

In this case, you only need to mix the desired pigment with the PP-R resin of the surface layer of the coating to give the plastic pipes 8A, 8B the desired color, but do not add the pigment to the pipe body material in order to avoid a decrease in water resistance.

Although the length of the vertical pipes 8B and horizontal pipes 8A are approximately selected and determined depending on the characteristics of the HR radiator, the radiator JR used in the 3 kW electric hot water heating system has a horizontal pipe length of 8A 1520 mm and a vertical pipe length of 8B is 400 mm In this case, the vertical pipes 8B are fused with the horizontal pipes 8A so that there is an interval gB of 7 mm between the corresponding vertical pipes 8B. Thus, the vertical pipes 8B and horizontal pipes 8A communicate with each other.

Each of the radiating panels 81, 82 contains vertical pipes 8B, welded to horizontal pipes 8A as shown in FIG. 3. The emitting section 8 is subjected to pressurized water to ensure that there are no leaks. Before installing the upper frame member 13 of a length of 1560 mm on the radiating section 8, the stops 13R of the lower plate 13B of the upper frame member 13 and the stops 13R of the hollow portion 13G are pressed against the upper horizontal pipes 8A so as to close the upper horizontal pipes and lower horizontal pipes 8A .

Then, the upper connectors 16 are mounted on the radiating section 8 on each side of the upper frame member 13, and the first protrusion 16E and the second protrusion 16E 'are pressed against the respective ends of the lower plate 13B of the upper frame member 13 from below, thereby inserting the second protrusion 16E' of the upper connector 16 into mounting hole H13 ".

Accordingly, in the HR radiator, the upper frame element 13, the upper connectors 16, the side elements of the frame 15, the lower connectors 17 and the lower frame element 14 have the same width (68 mm) and the materials of the frame elements are connected so that their surfaces are flush with each other on corresponding to the side surfaces of the frame F, therefore, the appearance of the HR radiator is attractive.

[Installation of the radiator HR (figure 2, 8)]

On Fig (A), 8 (B) schematically shows details that can be used to install the radiator HR. Fig. 8 (A) is a perspective view of the upper mounting bracket 10A, and Fig. 8 (B) is a perspective view of the lower mounting bracket 10B.

As shown in FIG. 8 (A), the upper mounting bracket 10A is made of steel plates and includes side vertical walls 10S and a central vertical wall 10M. The upper mounting bracket has a U-shape in plan, and a vertically elongated hole is made in the central vertical wall 10M, which allows you to adjust the installation position. On the upper part of the edge of the side walls 10S, protrusions 10G are made with rounded edges 10R, allowing these edges to abut against horizontal pipes 10A.

Further, as shown in FIG. 8 (B), the lower mounting bracket 10B is made of a steel plate in the form of a two-stage corner. In the vertical wall 10F of the lower mounting bracket 10B, a vertically elongated mounting hole HF is provided for adjusting the installation position. The two-stage corner comprises a first horizontal wall 10D and a second horizontal wall 10T, and a downward curved wall 10C is formed at the edge of the second horizontal wall. The second horizontal wall 10T is used as a support for the lower wall 14B of the lower element 14 of the HR radiator frame.

When mounting the radiator on the wall surface WL, as shown in FIG. 2, the upper mounting brackets 10A are rigidly fixed to the wall surface WL with screws 10N with an appropriate interval (standard: 800 mm), and side walls 10S are inserted between the corresponding vertical pipes 10B so that the outer curved abutment surfaces 10R of the protrusions 10G abutted in the upper horizontal pipes 8A of the first radiating panel 81, and the internal curved abutment surfaces 10R of the protrusions 10G abutted in the upper horizontal pipes 8A of the second radiating panel 82, thereby supporting the horizontal tubes 8A by the upper portions of the edges of the respective horizontal walls 10S, and supporting the lower end of the rigid hollow portion 13G at each of the lower ends of the upper frame member 13 by the upper edges of the vertical side walls 10S.

Further, the lower mounting bracket is rigidly fixed to the wall surface WL with screws 10N through the mounting hole HF, which allows you to adjust the vertical position of the center vertical wall 10M.

In this case, it is sufficient to attach the lower mounting bracket 10B to the wall surface WL so that the second horizontal wall 10T supports the lower wall 14B of the lower frame member 14.

Accordingly, the radiator HR will be in a state in which the upper horizontal pipes 8A of the radiating section 8 and the upper frame member 13 will be supported by the upper mounting brackets 10A, and the lower wall 14B of the lower frame member 14 will be supported by the lower mounting brackets 10B.

The expansion of the group of vertical pipes 8B due to the heating of the radiating section 8 does not interfere with operation, since the lower horizontal pipes 8A are freely suspended inside the lower frame member 14.

In addition, the expansion of the upper and lower horizontal pipes 8A due to heating of the radiating section 8 does not interfere with operation, since the horizontal pipes 8A are freely suspended inside the frame F.

The HR radiator of the present invention can serve as a compact radiator for space heating, having an attractive appearance taking into account the color scheme of the radiating section 8 open outside and the frame F, since the HR radiator is completely made of plastic, has a small weight and has a frame F. Further, it is easy is transported and mounted, and if the radiator is used, for example, together with the circulation system SY developed by the inventor of the present application, located in the housing 1, as shown in FIG. 1, excellent Iyu heating system for rooms.
