In the radiator of the conventional example 1 (FIG. 4), since the pipes are arranged in the horizontal direction, the resistance to flowing water is large, and when the number of pipes is large, each pipe is drifted and the temperature of the heat radiation surface is increased. It becomes inhomogeneous.
In addition, there are many fusion parts such as a fusion plate, a socket, a closing plate, and a pipe group, and the production is complicated, and the production work requires skill.

  Further, in Conventional Example 2 (FIG. 5), the branch pipe group is directly inserted into the main pipe mounting hole and heat-sealed, so the interval between the orthogonal positions of the branch pipes to the main pipe can be freely set, but the tip of the branch pipe is heated for the branch pipe. The main pipe of the branch pipe group in which the outer peripheral surface of the tip is melted by heat melting in the concave portion of the tool and the inner peripheral surface and the step portion of the first hole are also melted by the convex portion of the main pipe heating tool. Insertion and fusion into the mounting hole is a difficult task that requires skill, because manual insertion and pressing of the molten branch pipe group at the outer periphery of the tip into the molten main pipe at the inner peripheral surface of the mounting hole is difficult. Yes, it is difficult to perform uniform heat fusion fixing to the main pipe of a large number of branch pipe groups.

  In addition, the heat radiator of Conventional Example 3 (FIG. 6) is made of all plastic resin and integrated with two layers of heat radiation panels excellent in radiant heat radiation, so it is lightweight and has excellent thermal efficiency. However, in order to obtain uniform heat dissipation over the entire surface, it is necessary to attach each vertical pipe group to the horizontal pipe without communication distortion. Even with the excellent radiator manufacturing technology of Conventional Example 2, the large-diameter horizontal pipe The uniform and close joining of small-diameter vertical pipes is a cumbersome and skillful operation.

In addition, the first heat radiating panel is provided with a supply port at one end (right end) of the lower horizontal pipe, and the second heat radiating panel is provided with a discharge port at one end (right end) of the lower horizontal pipe. Since the flow path changing partition plate is interposed between the vertical pipe and the leftmost vertical pipe, the structure of the first heat radiating panel is different from that of the second heat radiating panel. Is complicated.
The present invention is intended to make it possible to more reasonably manufacture the functionally superior heat radiator of Conventional Example 3, and to provide a new and useful all-plastic resin heat radiator excellent in function and production. To do.

  In the present invention, as shown in FIG. 1, two sheets of first and second heat radiating panels in which a vertical pipe 2C group made of plastic and having the same diameter and the same length are connected between upper and lower headers 1 made of plastic resin are formed in a multilayer form. The all-plastic radiator is provided with a supply port 2S projecting from one heat radiation panel 101 and a discharge port 2R projecting from the other heat radiation panel 102. The header 1 has a large diameter main pipe 2A. The medium-diameter joint branch pipes 2B project sideways in parallel, and the upper and lower ends of each small-diameter vertical pipe 2C are fitted into each joint branch pipe 2B and heat-sealed. This is an all-plastic resin heating / cooling radiator.

  In this case, the header 1 and the vertical pipe 2C group may be made of a thermoplastic resin that can be heat-sealed and bonded, typically made of polypropylene, random, copolymer resin (PP-R resin). 2, the main pipe 2A has an outer diameter dA of 27 mm, a wall thickness tA of 5 mm, and a length L1 of 350 mm. The joint branch pipe 2B has an outer diameter dB of 17 mm and a wall thickness tB of 3.6 mm. The length LB is 30 mm, the center-to-center PA is 20 mm, and the vertical pipe 2C has an outer diameter dC of 13 mm, a wall thickness tC of 1.6 mm, and an exposed dimension h2 between the upper and lower branch pipes 2B is 1886 mm. is there.

  Accordingly, the radiator of the present invention is a multilayered form of two heat radiating panels made of all plastic pipe groups, so the heat generation and cooling efficiency per unit area is large. It is the subordinate (less than 30%) that circulates and heats the inside of the heat dissipating panels 101 and 102, and heats and heats the air around the heat dissipating panel. ), And the heat dissipation panel circulates warm water (standard: 60 ° C.), and the surface temperature (standard: 45 ° C.) does not cause burns even if touched by human hands. By summing up with radiant heat, it provides gentle heating that is gentle to the human body.

Further, during cooling, if cooling water (standard: 14 ° C.) is circulated in the heat radiating panels 101 and 102, convection cooling and radiation, mainly radiant heat cooling, follow convective cooling heat transfer of air as in the heating operation. The total cooling will create a uniform temperature environment with no spots in the room.
In addition, the joint branch pipe 2B group has a holding function as well as a header function with respect to the vertical pipe 2C group. Therefore, it is easy to connect the vertical pipe 2C group to the header 1, and the vertical pipe 2C group is uniform. Ensures the function of running water and durability.
And since it is made of all plastic resin, it is lightweight and has excellent manufacturing, transportation, and mounting workability, and can be arranged in a suspended form via the upper header 1, so that the space in the partition wall of the building, etc. It is possible to construct a concealed heating / cooling system in a narrow space.

In the radiator of the present invention, the joint branch pipe 2B is provided with a mounting hole Hb for fitting the vertical pipe 2C from the tip, as shown in FIG. 2, and the tip Cf of the vertical pipe 2C is connected to the mounting hole Hb. The branch pipe 2B and the vertical pipe 2C are connected to and integrated with the inner peripheral surface in a flush manner by heat fusion from the outer peripheral surface of the mounting hole Hb. Is preferred.
In this case, as shown in FIG. 2B, heat fusion between the branch pipe 2B and the vertical pipe 2C is performed by covering and sandwiching the entire outer periphery of the mounting hole Hb with a heating jig, so that the entire outer periphery of the branch pipe 2B is covered. What is necessary is just to fuse | melt and fuse | fuse with the vertical pipe 2C.

Accordingly, the insertion of the vertical pipe 2C into the attachment hole Hb of the joint branch pipe 2B is an operation in a state in which both pipe pieces have a shape retaining property at room temperature, and the manual insertion operation of the vertical pipe 2C is performed. It can be carried out easily and accurately, and the fusion splicing with the branch pipe 2B for joint of each vertical pipe 2C group can be carried out uniformly and reliably.
Since the outer periphery of the vertical pipe 2C is fused to the inner periphery of the melted branch pipe 2B, but the inner periphery can be connected and integrated with the branch pipe 2B in a state where no melt displacement occurs, the vertical pipe 2C and the branch pipe It is possible to connect 2B to the inner peripheral surface, and to provide a joint with a uniform water flow function and without risk of withdrawal or leakage.

  In the radiator of the present invention, as shown in FIG. 3, the first heat radiating panel 101 and the second heat radiating panel 102 are the same, and each end of the upper and lower header main pipes 2A is closed by a closing plate 2F. The upper header main pipe 2A projects the connection port 2S (2R) from one end, and a partition plate 2P is disposed between the first and second vertical pipes 2C from the other end. The other end of the header main pipe 2A is communicated between the partition plate 2P and the closing plate 2F by a communication pipe 2D, and one end of the upper header main pipe 2A and both ends of the lower header main pipe 2A are fixed by spacer pipes 2E. Is preferred.

In this case, the connection ports 2S and 2R are pipe pieces obtained by cutting the vertical pipe 2C material into short pieces (standard: 50 mm), and the connection ports on the first heat radiation panel 101 side are the supply ports 2S and the second heat radiation panel 102 side. The connection port becomes the discharge port 2R.
In addition, the first heat radiating panel 101 and the second heat radiating panel 102 having the same structure have four corners, that is, both ends of the upper header main pipe 2A and both ends of the lower header main pipe 2A at one corner and a communication pipe 2D, and at the other three corners. Although integrated with the spacer pipe 2E, the space between the two heat dissipating panels 101 and 102 can be arranged in a narrow space, for example, in a partition wall of a building, etc. As shown in FIG. 3, the radiator typically has a total height h1 of 2000 mm, a vertical pipe exposure length h2 of 1886 mm, a thickness W1 of 58.5 mm, the first heat radiation panel 101 and the second heat radiation. The distance gs between the header main pipes 2A and the panel 102 is 4.5 mm allowing a minimum air flow, and the panel surface distance gp is 18.5 mm.

  Therefore, as shown in the front view (B) and the back view (D) of FIG. 3, the heat radiator of the present invention is prepared for mass production of two heat dissipating panels having the same structure, and the two heat dissipating panels are prepared as necessary. Since it can be manufactured simply by integrating at the four corners in the form of multiple layers, the manufacturing and preparation of the radiator can be streamlined.

  And the obtained heat radiator is the supply flow f1 of the warm water for heating from the supply port 2S of the one end (right end) of the 1st heat radiating panel 101, or the cooling water supply flow f1 in the upper main pipe 2A. Inner descending flow f3 → lower main pipe 2A inner transverse flow f4 → left end vertical pipe rising flow f5 → communication flow 2D in communication pipe 2D into second heat radiation panel 102 → second heat radiation panel in left end vertical pipe lowering It circulates through the path of flow f7 → cross flow f8 in the lower main pipe 2A → upward flow f9 in the vertical pipe → cross flow f10 in the upper main pipe 2A → discharge flow f11 at one end (right end) of the radiator.

  Therefore, the radiator has a narrow front and rear width W1 and is a radiator with excellent thermal efficiency mainly for radiant heat radiation during heating or cooling, and is suitable for hanging arrangement in a narrow space such as in a partition wall space of a building. Providing a radiator, connecting the forward pipe S to the supply port 2S of the radiator and the return pipe R to the outlet 2R of the radiator, supporting the radiator itself in a suspended form. Therefore, it is possible to construct a heating / cooling system that mainly uses radiant heat and exhibits high thermal efficiency by arranging it in a space in the partition wall of the building in a concealed form.

Further, in the radiator of the present invention, the vertical pipe 2C group is closely arranged in such a manner that the interval gc between the vertical pipes 2C allows the minimum flow of the heating air during heating and the cooling air during cooling. It is preferable to do this.
In this case, the heat generation amount per unit area of the vertical pipe 2C group increases as the density increases. However, if the space (interval) between the vertical pipes 2C is reduced, the air heated or cooled on the peripheral surface of the vertical pipe 2C. However, it stays with the viscous resistance with respect to the peripheral surface of the vertical pipe, and natural convection is suppressed.

In addition, ascending flow behavior of the heated air with respect to the vertical heating surface is 0.024 m / s when it is 5 mm away from the heating vertical surface, 0.057 m / s when it is 20 mm away, and downward when it is 20 mm or more away. Cold air is generated.
The upward flow behavior of the heated air also corresponds to the downward flow behavior of the cooling air around the vertical pipe 2C during cooling.
Therefore, if the gap gc between the vertical pipes 2C is 5 to 10 mm (standard: 7 mm), the heat radiation panels 101 and 102 have a large heat radiation amount, and the necessary air flow between the vertical pipes 2C can be guaranteed.

  Accordingly, the heat radiator is supplied with heating water (standard: 60) from the header main pipe 2A having a large diameter (outer diameter: 27 mm, inner diameter: 17 mm) to the vertical pipe 2C group having a small diameter (outer diameter: 13 mm, inner diameter: 9.8 mm). ° C) or cooling supply water (standard: 14 ° C) flows all at once to provide a heating surface or a cooling surface with no temperature difference, and for each of the vertical pipes 2C group constituting the heat radiation surface of the two-piece heat radiation panel Between the vertical pipes 2C, only the heated air flows during heating and only the cooling air flows during cooling without causing viscous retention of the air, and exhibits a highly efficient heat dissipation action.

Since the radiator of the present invention is made of all plastic resin, it is lightweight and easy to manufacture, transport, and mount.
And since it is the laminated | stacked form of two heat radiating panels, the thermal radiation amount per unit area of heating and cold becomes large, and provides a lightweight and high-performance heat radiator.
Moreover, since the vertical pipe 2C group constituting the heat radiating surface is fitted into the joint branch pipe 2B group of the header 1 and is heat-sealed, the joint branch pipe 2B in a state of maintaining shape retention at room temperature. It is easy to fit the vertical pipe 2C into the inside, and it is easy to manufacture each heat radiating panel.
And since the branch pipe 2B group for joints also has a holding function of the vertical pipe 2C, it guarantees the uniform water flow function and durability of the vertical pipe 2C group.

In addition, the vertical pipe 2C group that constitutes the heat generating surface of the radiator has a heat generation and cooling effect that is free from spots from the entire surface of the radiator due to the simultaneous water flow action from the upper and lower header main pipes 2A. (Slightly over 70%), and by the total action of radiant heat and natural convection heat that follows natural convection (slightly less than 30%), it exhibits gentle heating and cooling that is gentle to the human body, and there is no uncomfortable forced air flow. It is possible to provide a high-quality heating / cooling system that warms and cools the living room without any spots.
And since the arrangement of the radiator can be suspended through the upper header 1, it can also be arranged in the partition wall space of the building, and a new concealment arrangement heating / cooling system in the partition wall space is possible. Construction is also possible.

The arranged shape is prepared by injection molding with polypropylene, random, copolymer resin (PP-R resin).
Further, as shown in FIG. 2 (B), the vertical pipe 2C group is extruded with PP-R resin as a pipe material having an outer diameter dC of 13 mm and a wall thickness tC of 1.6 mm, and is fixed (standard: 1906 mm). ) To prepare.

As shown in FIG. 2 (B), the branch pipe 2B group of the header 1 is divided into a vertical pipe 2C group, and as shown in FIG. 2B, the tip Cf of the vertical pipe 2C having an outer diameter of 16 mm is a step bf at the far end of the mounting hole Hb having an inner diameter of 13 mm. Although not shown in the drawing, when the vertical pipes 2C are inserted into all the branch pipes 2B of one header 1 one by one in the contact form, the branch pipe 2B has a width of 6 mm. A heating jig having a semicircular curved surface that matches the outer periphery curvature is covered and sandwiched from the front and rear to the outer periphery of the mounting hole Hb of the branch pipe 2B over the entire circumference, and the joint branch pipe 2B is melt-pressed. The branch pipe 2B and the vertical pipe 2C are fusion bonded.
In this case, as shown in FIG. 2B, the joining form of the header branch pipe 2B and the vertical pipe 2C is such that annular small protrusions of the fusion resin 2M are formed on both sides of the fusion part 2T in contact with the heating jig. However, the inner peripheral surface of the vertical pipe 2C is flush with the inner peripheral surface of the branch pipe 2B.

Next, if the other end header 1 is fusion-bonded to the other end of the vertical pipe 2C group fused and connected to one header 1 in the same manner, the header 1 is integrated at both ends of the vertical pipe 2C group. Will be.

Then, at the boundary between the vertical pipe 2C at the outermost end (left end) and the next vertical pipe 2C, a partition plate 2P of a plastic piece is arranged in the header main pipe 2A, and at one end (right end) of the upper header main pipe 2A, If the pipe piece obtained by cutting the pipe for the vertical pipe 2C is provided as a supply port 2S or a discharge port 2R so as to communicate upward, the total height h1 is 2000 mm, the exposed length h2 of the vertical pipe 2C group is 1886 mm, and the total width L1 is 350 mm. Thus, an all-plastic resin heat radiation panel having a gap gc between the vertical pipes 2C of 7 mm is obtained.

[Production of radiator He (Figs. 1 and 3)]
The heat radiator He of the present invention is formed by stacking two pieces of all plastic resin heat radiating panels of the same structure in a form in which the upper projecting pipe piece of the upper header main pipe 2A, that is, the connection port pipe piece 2S (2R) is aligned in the front-rear direction. The upper end of the upper header main pipe 2A and the lower end of the lower header main pipe 2A are connected and integrated. In this case, the space Sa defined by the closing plate 2F and the partition plate 2P at one corner of the upper header main pipe 2A is The communication pipe 2D is connected to each other, and the other three corners, that is, the end from which the pipe piece 2S (2R) protrudes and the both ends of the lower header main pipe 2A are simply integrated with a spacer pipe 2E having a gap therebetween.

  When the front heat radiation panel, that is, the first heat radiation panel 101, and the rear heat radiation panel, that is, the second heat radiation panel 102 are joined and integrated, as shown in FIG. 1B and FIG. If the distance gs between the opposite header main pipes 2A is kept at 4.5 mm and integrated, the distance gp between the vertical pipe 2C group surfaces of both pipes becomes 18.5 mm, and the radiator He has a front and rear thickness W1 of 58.mm. The heat radiation panel 101, 102 multi-layer type is 5 mm, the width L1 is 350 mm, the total height h1 is 2000 mm, and the exposed length h2 of the vertical pipe 2C group is 1886 mm.

  As shown in FIG. 3, when the obtained radiator He is supplied with hot water or cooling water from the supply port 2S of the upper projecting pipe piece of the first heat radiating panel 101, the supply water flow f1 is simultaneously transmitted from the upper header main pipe 2A. The vertical pipe 2C group is moved down to rise from one vertical pipe 2C at the end of the lower header main pipe 2A, and the second pipe passes through the communication pipe 2D from the space Sa defined by the closing plate 2F and the partition plate 2P. It flows into the space Sa of the closing plate 2F and the partition plate 2P of the heat radiating panel 102, descends from the space Sa of the second heat radiating panel, and ascends the vertical pipe 2C group from the lower header main pipe 2A, and from the upper header main pipe 2A.
