More specifically, the present invention relates to a lightweight, small depth thickness, and large heat dissipation. The present invention relates to a radiator that is effective for placement in a space with a small storage depth such as a partition of a building that does not require air venting, and belongs to the technical field of indoor heating and cooling of a building.

A heat radiator in which the hot water circulation heat dissipating part is made of plastic has already been proposed by Conventional Example 1 shown in FIG. 6, Conventional Example 2 shown in FIG. 7, Conventional Example 3 shown in FIG.
Conventional Example 1 (FIG. 6) is a hot water circulating radiator disclosed in Patent Document 1, and FIG. 6 (A) is a heat radiating part by bending and extending one of plastic pipes. , (B), a plurality of pipes are arranged in parallel and both ends are connected by a socket, a forward pipe is connected to the upper end of the socket at one end, a return pipe is connected to the lower end of the socket, and the return side pipe is connected to the return side pipe. The hot water is circulated through all the pipes, (C) is an explanatory view of water flow in the socket part, and (D) is a perspective view of the socket part.

Further, Conventional Example 2 (FIG. 7) is cited as Patent Document 2, and the present inventor has developed two heat dissipating panels developed as a heat dissipator suitable for a hot water circulation heater for floor mounting. 7A is a front view of the first heat radiating panel side, FIG. 7B is a left side view of the radiator, and FIG. 7C is a right side view of the heat radiating section. (D) is a front view for the back side, that is, the second heat radiation panel side.
That is, as shown in FIG. 7 (A), the first heat radiating panel is integrated with the vertical pipe group between the upper and lower horizontal pipes, the vertical pipe tip is fitted into the insertion hole of the horizontal pipe, and is fused and fused. The ends of the upper and lower horizontal pipes are closed with a closing plate, and the supply port projects downward from one end (right end) of the lower horizontal pipe.

In addition, as shown in FIG. 7 (D), the second heat radiating panel is integrated with the vertical pipe group between the upper and lower horizontal pipes, and the vertical pipe tip is fitted into the insertion hole of the horizontal pipe and thermally integrated. The end of the upper and lower horizontal pipes is closed with a closing plate, and at the other end (left end) of the upper horizontal pipe, a partition plate is arranged while maintaining one vertical pipe from the closing plate, and one end (right end of the lower horizontal pipe) ), The partition plate is disposed while maintaining one vertical pipe from the closing plate, and the discharge port is disposed below between the closing plate and the partition plate.
Then, as shown in FIG. 7 (B), the first heat radiating panel and the second heat radiating panel are connected to the left end (the other end) on the upper side by a communicating pipe on the upper side, and on the lower side, between the end of the horizontal pipe. Are connected by a spacer pipe, and the upper and lower sides of the right end (one end) are connected by a spacer pipe between the ends of the horizontal pipe.

  Accordingly, as shown in FIG. 7, the hot water supplied from the supply port at the lower end of the first heat radiating panel is f1 flow at the supply port → left flow f2 flow in the lower horizontal pipe → upflow f3 flow of the vertical pipe group → upper side. Left side f4 flow of horizontal pipe → f5 flow from the first heat dissipating panel to the second heat dissipating panel in the communication pipe → left end vertical pipe by the closing plate and partition plate at the other end (left end) of the upper horizontal pipe of the second heat dissipating panel Downward f6 flow in the right row f7 flow to the partition plate of the lower horizontal pipe → Upward f8 flow of the vertical pipe group → Right row f9 flow from the partition plate of the upper horizontal pipe to one end (right end) in the vertical pipe The descending f10 flow → the f11 flow from the discharge port, and the hot water circulates in the two panels in the form of multiple layers.

  In addition, Conventional Example 3 (FIG. 8) was developed by the inventor as a hot / cold water circulation radiator suitable for concealment arrangement in a building partition, and is cited as Patent Document 3, This is an all-plastic resin heatsink in which two heat radiation panels are integrated, with (A) showing a partial cross-sectional plan view of the header and (B) showing the relationship between the header and the vertical pipe. FIG. 4C is a partially enlarged plan view of the heat dissipation panel.

In other words, Conventional Example 3 (Fig. 8) is prepared by injection molding of a joint branch pipe group with a medium diameter (17mm) laterally projecting from a large diameter (27mm) header main pipe to the side with a center distance of 20mm by injection molding. A vertical pipe 2C group having a small diameter (13 mm) is connected between the upper and lower headers to form an all-plastic resin heat dissipating panel, and the two heat dissipating panels are connected and integrated in a multilayered structure to form a heat radiator. .
The connection between the header and the vertical pipe group is made by manually fitting the ends of the vertical pipes one by one into the mounting hole located at a depth of 10 mm from the tip on the inner periphery of the joint pipe for the header. The outer periphery of the joint branch pipe is melted by a heating tool, and the joint branch pipe and the insertion vertical pipe in the outer peripheral portion are fused.

In the radiator of the conventional example 1 (FIG. 6), since the pipes are arranged in the lateral direction, the flowing water resistance 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.
And since the air in a radiator accumulates in the uppermost part of a flowing water path, arrangement | positioning of the air venting apparatus is required for the upper end of a radiator.
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.

In addition, the heat radiator of Conventional Example 2 (FIG. 7) is made of all plastic resin and has two layers of heat radiation panels excellent in radiant heat radiation. However, since the lower end horizontal pipe interval and the upper end weft pipe interval between the first panel and the second panel are smaller than the vertical pipe surface interval as the heat dissipating surface, the vertical through-air flow in the space between both panels The air flow is stagnant and convective heat transfer cannot be carried out smoothly.
Also, 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 any communication distortion, and the uniform dense joining of the small diameter vertical pipe group to the large diameter horizontal pipe is cumbersome and requires skill. Work.

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.
And since the air in circulating water accumulates in an upper end horizontal pipe, like the prior art example 1 (FIG. 6), arrangement | positioning of the air venting apparatus is required at the upper end of a radiator.

In addition, the radiator of the conventional example 3 (FIG. 8) has a branch pipe group for joints having a medium diameter (outer diameter of 17 mm) from the side of a header main pipe having a large diameter (outer diameter of 27 mm), a center distance of 20 mm, that is, a joint. It is complicated and expensive to manufacture a mold for injection-molding a header having a mounting hole having a depth of 10 mm from the tip of the joint branch pipe, with the interval between the branch pipes protruding at 3 mm.
In addition, the thickness of the joint branch pipe is limited from the viewpoint of the flow-in effect of the molten resin in the mold, and the formation and use of nests at the joint between the joint branch pipe and the header main pipe is restricted. In order to avoid the risk of cracking due to heat stress and hydraulic load, the thickness of the joint branch pipe is limited.

Then, the fusion bonding of each vertical pipe to each joint branch pipe is a fusion joint obtained by covering and sandwiching the outer peripheral surface of each joint branch pipe with a pair of upper and lower heating tools (not shown). Even when aiming to increase the density of the vertical pipe group with the aim of increasing the heat dissipation of the pipe, the fusion interval of the branch pipes for each joint is the minimum necessary for inserting and interposing a pair of upper and lower heating tools (standard: 3 mm) ) Is required.
Therefore, in the radiator of the conventional example 3 (FIG. 8) in which a vertical pipe is inserted into the joint branch pipe and the vertical pipe is fused and integrated into the joint branch pipe, The vertical pipes are fitted into the joint branch pipes and fused and integrated under the minimum required dimensions of the wearing interval, so the vertical pipe spacing is also minimized compared to the joint branch pipes ( Standard: 7mm), and the maximum number of vertical pipes per unit width is limited to increase the heat generation of the radiator.

  In the present invention, the heat radiator excellent in function of the conventional example 2 (FIG. 7) and the conventional example 3 (FIG. 8) can be manufactured more rationally by increasing the heat radiation amount. The problem of the injection mold is reduced, the distance between the vertical pipes is made smaller, the heat radiation amount per unit area can be increased, and the installation of the air venting device at the upper end of the radiator is also unnecessary. It is a new and extremely practical heatsink made of all plastic resin that is superior in function, design, and production.

  As shown in FIG. 1, the present invention includes a first heat radiating panel 101 in which a group of heat dissipating weft pipes 2A made of plastic resin and having the same diameter and the same length are connected between the left and right headers 1 made of plastic resin. 2 is an all-plastic resin radiator in which two sheets of the heat radiating panel 102 are integrated and communicated in a layered form, and the first and second heat radiating panels are mounting holes on the side surface of the large-diameter main pipe 1A of the header 1 A small-diameter weft pipe 2 </ b> A group is fitted and communicated with the Ha group, the weft pipe 2 </ b> A group communicates with the headers 1 on both sides, and a supply port 1 </ b> S is provided at the upper end of the header 1 at one end of the first heat radiation panel 101. A discharge port 1R is provided at the upper end of the header 1 at one end of the heat radiating panel 102, and the water flow of the entire weft pipe 2A group of the first and second heat radiating panels flows in from each header main pipe 1A and out to each header main pipe 1A. Both in header main 1A Those carried out at elevated flow.

  In this case, the header main pipe 1A and the weft pipe 2A may be made of a thermoplastic resin that can be heat-sealed to each other, and are typically made of polypropylene, random, copolymer resin (PP-R resin). The diameter header main pipe 1A is an injection-molded product having an outer diameter d1 of 27 mm and a wall thickness of 5 mm, and as shown in FIG. The small-diameter weft pipe 2A is an extruded product having an outer diameter d2 of 13 mm and a wall thickness of 1.6 mm. As a typical heat radiation panel, the upper and lower sides of the header main pipe 1A are closed plates as shown in FIG. A weft pipe 2A is integrally connected with an exposed length of 946 mm (L2) to a header 1 having a total height h1 of 451 mm closed at 1F.

  In addition, as shown in FIG. 1, heat dissipation with a supply port 1 </ b> S at the upper end of one end (right side) header 1 of the first heat radiation panel 101 and a discharge port 1 </ b> R at the upper end of one end (right side) header 1 of the second heat radiation panel 102. As shown in FIG. 5, the water flow f1 from the supply port 1S of the first heat radiating panel 101 is guided by the downflow f2 in the header main pipe 1A, and the direction is changed to the upflow f3 at the lower end of the header main pipe 1A. Then, the upward flow f5 supplied from the upward flow f3 of the header main pipe 1A to each weft pipe 2A and collected by the header main pipe 1A at the other end (left side) is connected to the other end (left side) of the second heat radiation panel by the communication pipe piece 1D. ) In the other end (left side) of the header main pipe 1A of the second heat radiating panel 102, the downward flow f7 up to the lower end is changed to the upward flow f8 by changing the direction to the upward flow f8. Each pie from f8 If the upflow f10 collected in the header main pipe 1A at one end (right side) is circulated as the discharge flow f11 from the discharge port 1R, the water flow in the entire weir pipe 2A group of the radiator is In addition, all the discharged water is carried out in the upward flow in the header main pipe 1A.

  Therefore, in the radiator of the present invention, the first heat radiating panel 101 has a lower end position of the header main pipe 1A provided with the supply port 1S, that is, a substantially water flow supply position to the weft pipe 2A group of the first heat radiating panel 101. To the upper end position of the header main pipe 1A at the other end, that is, the discharge position of the flowing water of the first heat dissipating panel 101 to the second heat dissipating panel 102, each flowing water path through each weft pipe 2A has the same length, Ascending flow in the header main pipe 1A at one end is distributed and flows into the respective weft pipes 2A, and the flowing water of each weft pipe 2A group is collected as the ascending flow in the header main pipe 1A at the other end. The heat dissipating surface has a substantially uniform heat dissipating action.

The second heat radiating panel 102 also has a header main pipe at one end (right side) from the lower end position of the header main pipe 1A at the other end (left side), that is, a substantially water flow supply position to each weft pipe group of the second heat radiating panel 102. Each flowing water path passing through each weft pipe 2A up to the upper end position of 1A, that is, the flowing water discharge position of the second radiator panel 102 has the same length, and the upward flow from the lower end position of the header main pipe 1A at the other end is In order to flow into each weft pipe 2A and collect as an upward flow in the header main pipe 1A at one end, the second heat dissipating panel 102 also has a substantially uniform heat dissipating action.
Therefore, the entire surface of the first heat radiating panel 101 and the entire surface of the second heat radiating panel 102 exhibit substantially uniform heating or cooling heat generating action within the surface, thereby providing a high-quality panel radiator.

Further, since it is made of all plastic resin, it is lightweight, easy to handle, and provides a high-performance radiant heat heater / cooler based on high absorption and high radiation of the radiant heat rays of the material itself.
And since the heat sink has a large-diameter header main pipe 1A on both sides, the distance between the weft pipe 2A group surfaces of the first heat radiating panel 101 and the second heat radiating panel 102, that is, the distance between both heat radiating panels is The upper and lower openings have the same dimensions from the lower end to the upper end, and the up and down flow of the heating or cooling air in the radiator is smooth without stagnation and convective heat transfer is improved.

In addition, the header main pipe 1A as a constituent material of the radiator can be prepared with a simple and inexpensive shape injection mold, the weft pipe 2A can be prepared by extrusion molding, and the arrangement of the mounting holes Ha to the header main pipe 1A is also possible. Since it is flexible, it is possible to easily and inexpensively manufacture a high performance heat dissipating panel in which weft pipes 2A are closely arranged in parallel, and a high performance heat radiator can be rationally manufactured.
In addition, the air in the radiator generated by the circulating water is also discharged from the uppermost weft pipe 2A to the discharge port 1R, eliminating the need for an air venting device for each radiator, resulting in high performance and availability. An excellent heat radiator can be provided.

  In the radiator of the present invention, as shown in FIG. 1, the other end of the first heat radiating panel 101, that is, the upper end of the header main pipe 1A on the left side in FIG. The upper end of the header main pipe 1A at the other end communicates with the communication pipe piece 1D, and one end of the first heat radiating panel 101, that is, the other end of the header main pipe 1A and the second heat radiating panel 102 on the right side in FIG. It is preferable that the header main pipe 1A on the left side of FIG. 1A converts the downward flow flowing from the upper end into the upward flow at the lower end and supplies it to each weft pipe 2A.

In this case, the first heat dissipating panel 101 and the second heat dissipating panel 102 may be integrated at the upper, lower, left and right corners, and the other end, that is, the communication pipe piece 1D on the left and upper corners, together with the flowing water supply function. The other three corners may be simply integrated with the spacer pipe 1E.
Also, the means for converting the downward flow in the header main pipe 1A into the upward flow extends and hangs down the pipe for the downward flow into the header main pipe 1A to the lower end of the header main pipe 1A, for the downward flow inside the pipe and ascends the outside of the pipe The header main pipe 1A may be divided into a downward flow route and an upward flow route communicating with the weft pipe 2A group.

Accordingly, the circulating water is supplied to each weft pipe 2A group of the first heat radiating panel 101 from above and below each weft pipe from the lower end of the header main pipe 1A having the supply port 1S to the other end to the upper end of the header main pipe 1A. The flow resistance through the weft pipe 2A is substantially the same, and even within the second heat radiating panel 102, it passes through the weft pipe 2A from the lower end of the header main pipe 1A at the other end. It becomes a flowing water route to the upper end of the one-end header main pipe 1A, and the flowing water resistance in each weft pipe 2A becomes substantially the same.
Therefore, both the first heat dissipating panel 101 and the second heat dissipating panel 102 have a substantially uniform heat generating action on the entire panel surface of the weft pipe 2A group, and a high performance heat dissipator that does not generate heat generation spots. It becomes.

In the radiator of the present invention, as shown in FIG. 3, the header main pipe 1A at one end of the first heat radiating panel 101 is an insertion pipe 1B for flow conversion from the upper end to the lower surface level of the lowermost weft pipe 2A. The header main pipe 1A at the other end of the second heat radiating panel 102 is provided with an insertion pipe 1C for converting the flow from the upper end to the lower surface of the lowermost weft pipe 2A, and the insertion pipe 1C is the first heat radiating panel. It is preferable to communicate with the header main pipe 1A at the other end of 101 by a communication pipe piece 1D at the top.
In this case, in each of the insertion pipes 1B and 1C, the feed water that descends the insertion pipes 1B and 1C is placed in the header main pipe 1A between the lower end of the lowermost weft pipe 2A and the lower end closing plate 1F. It is only necessary that there is a gap for jetting out, and typically, the gap between the insertion tubes 1B and 1C and the closing plate 1F at the lower end is 2 mm.

  Therefore, the insertion pipes 1B and 1C can be easily arranged in the header main pipe 1A via the closing plate 1F at the upper end of the header main pipe 1A, and both the insertion pipes 1B and 1C are at the level of the lower surface of the lowermost weft pipe 2A. Therefore, the lowermost weft pipe 2A is also subjected to the lateral inflow action from the same reverse upflow as the upper weft pipes 2A, and the lowermost weft pipe is subjected to the direction-changing jet of the descending feedwater stream to the upward feedwater stream. Circulating water supply with substantially uniform flow resistance can be imparted to all the weft pipes 2A from 2A to the uppermost weft pipe 2A.

In the radiator of the present invention, as shown in FIG. 3D, the header main pipe 1A at one end of the first heat radiating panel 101 and the header main pipe 1A at the other end of the second heat radiating panel 102 1P is provided up to the lower surface level of the lowermost weft pipe 2A, and the upper end of a half of the descending flow path defined by the flowing water partitioning piece 1P of the header main pipe 1A at the other end of the second heat radiating panel 102, It is preferable that the header main pipe 1A at the other end of the heat radiation panel 101 communicate with the communication pipe piece 1D.
In this case, the flowing water partition piece 1P can be easily attached to the header main pipe 1A by integral molding.

Therefore, in the header main pipe 1A, since the flowing water partition piece 1P functions as a reinforcing rib, the rigidity of the entire radiator is improved, the handling becomes easy, and the first heat radiating panel 101 and the second heat radiating panel 102 are communicated. The splicing connection or the adhesive connection of the short communication pipe piece 1D is also facilitated.
The header main pipe 1A provided with the flowing water partitioning piece 1P is positioned at the lower surface level of the lowermost weft pipe 2A with the lower end of the partitioning piece 1P, so that the reverse upflow is uniformly circulated to each weft pipe 2A group. Water supply flow.

Further, in the radiator of the present invention, as shown in FIG. 1, the first and second heat radiating panels 101 and 102 are provided with a plurality of blocks 2 of closely weft pipes 2A for crossing the air flow. It is preferable to arrange them repeatedly with an interval g2.
In this case, the closely integrated block 2 of the weft pipes 2A may be formed in the form of this section one by one by hand when the weft pipes 2A are fused to the header main pipe 1A. Typically, however, a plurality (standard: 3) of weft pipes 2A are prepared by extrusion in a parallel contact form.
Further, if the gap g2 for crossing the air flow is increased, the air crossing function is increased. However, the arrangement of the gap g2 in the heat radiating surface simultaneously reduces the number of the weft pipes 2A arranged per unit area. In order to reduce the heat radiation amount, typically, in the weft pipe 2A group, three integrated blocks 2 are arranged with a gap g2 of 5 mm.

Therefore, the heat dissipating panels 101 and 102 have the air flow crossing gap g2 in place, and the weft pipes 2A are closely packed without gaps in the block 2 of each weft pipe 2A. Under the increase in the heat radiation amount due to the arrangement, the heat radiation surface contact is caused by the turbulent flow of air through the gap g2 between the upper and lower through-opening spaces in the radiator, that is, the space between both panels, and the outside of the radiator. The movement of the surface air becomes large, improving the heat transfer between the heat radiating portion and the surrounding air, and improving the convective heat release effect of the entire radiator.
Moreover, the gap g2 can be used as a suspended holding portion of a lightweight radiator.

  In the radiator of the present invention, as shown in FIG. 1, the first heat radiating panel 101 and the second heat radiating panel 102 have a minimum gap gp that guarantees the up-down flow of the air flow between the heat radiating panels. The gap g2 for crossing the air flow between the blocks 2 in each panel is preferably a small gap of 4 to 6 mm that allows turbulence to flow in and out between the inter-panel space and the panel outer surface.

In this case, the gap gp between the heat dissipating panels is a distance between the weft pipe 2A group surfaces of both heat dissipating panels.
And if the space | interval gp between panel surfaces is large, the air heated by the heat radiating surface will become a smooth upward flow, but if too large, the non-heating counterflow from the upper and lower to the center part of both heating surfaces will be carried out. If it is small, the draft rise of heated air will be suppressed by air viscosity.

  Further, the interval g2 between the blocks 2 is a dimension for inflow and outflow of the transverse air between the interval gp between the panels and the outer surface of the panel, and permits the parallel vertical interlayer movement of the air heating layer and the normal temperature layer. If the dimension g2 is large, the transverse air flow becomes large, but the number of weft pipes 2A arranged per unit dimension on the panel surface decreases, so the interval g2 in the block 2 is 4 to 4 If it is in the range of 6 mm, it is possible to suppress a decrease in the number of weft pipes 2A arranged per unit dimension and to effectively generate an air flow across the panel.

  Therefore, the radiator of the present invention has a configuration in which the panel surfaces of the first heat radiating panel 101 and the second heat radiating panel 102 ensure the up and down flow of the draft air flow, and the spaces between the blocks 2 of the vertical panel 2A. Since g2 is provided, the draft airflow generated between the panel surfaces, that is, the upward flow during heating and the downward flow during cooling, and the upward or downward flow generated on both sides of the panel surface are turbulent on the heat dissipation surface. And the flow of air on the surface of the panel through the gap g2 is increased and flows in and out. The presence of the gap g2 between the weft pipe blocks 2 allows the gap between the panel planes even if the gap gp is small. Air flow stagnation in the space can be eliminated, convection heat dissipation from the radiator is smooth, and heat dissipation action by convection heat transfer is improved.

Since the heat radiator of the present invention is made of all plastic resin, it is lightweight and easy to manufacture and carry.
Since the header main pipe 1A is simplified to a structure having a mounting hole Ha group on the side surface of a large-diameter pipe, the injection mold can be manufactured inexpensively and easily, and a homogeneous and high quality header main pipe 1A can be prepared. .
The heat radiation panels 101 and 102 are manufactured by fitting and welding the weft pipe 2A group prepared by extrusion molding to the header main pipe 1A. And can be implemented at low cost.

  In the heat radiator in which two heat dissipating panels are integrated in a multilayered form, each header 1 having a large-diameter header main pipe 1A serves as both sides, and two heat dissipating surfaces of closely parallel weft pipes 2A are draft air. Since the space of equidistant gp allowing the up and down flow of the flow is opened up and down, the space between the heat radiating surfaces, that is, the space of the space gp, flows up and down without heating and cooling air flow stagnating, Convective heat transfer is improved.

  Further, the circulating water path in the radiator also includes a path from the supply port 1S at the upper end of the header at one end of the first heat dissipation panel 101 to the discharge port 1R at the upper end of the header at the one end of the second heat dissipation panel 102. 2 In each panel, the water flow of the entire weft pipe 2A group is carried out by the inflow from each header main pipe 1A → the weft pipe 2A → the outflow to each header main pipe, and the upward flow in the header main pipe 1A. The water path length for each weft pipe 2A in each panel from the supply port 1S to the discharge port 1R is the same, and each panel surface exhibits a substantially uniform heat generating action.

  In addition, since both the supply port 1S and the discharge port 1R of the radiator are arranged at the upper end of the header main pipe 1A on the same side, the upper pipe such as a ceiling pipe can be easily connected on one side, Since the weft pipe 2A at the uppermost end of the second heat radiating panel is filled and circulated by the introduction flow from the upward flow of the header main pipe 1A, air accumulation at the uppermost end of the panel can be suppressed, and the air in the water flow circulation path Provided is a heat radiator that does not cause accumulation and does not require an air vent.

[Structure of heat radiator (Fig. 1)]
As shown in FIG. 1, the overall shape of the radiator to be manufactured is a weft pipe 2A group having an outer diameter d2 of 13 mm between the left and right header main pipes 1A, an exposed length L2 of 946 mm, and each weft pipe. The 2A group is a block 2 in a unitary close-packed form of 3 pieces, and the first heat radiation of the same shape with a total length L1 of 1000 mm and an overall height h1 of 451 mm, which is integrated with a gap g2 between the blocks 2 of 2 mm. The distance between the weft pipe 2A group surface of the first heat dissipating panel 101 and the weft pipe 2A group surface of the second heat dissipating panel 102 is 18.5 mm. The gap gs between the header main pipe 1A and the header main pipe 1A of the second heat radiating panel 102 is 4.5 mm, and both the heat radiating panels 101 and 102 are joined and integrated at the four corners of the upper, lower, left and right sides, that is, the front and rear width, that is, the depth W1 is 58. 5mm, free Vessels of one end of the upper end of the header main 1A of the first radiator panel supply ports 1S, the upper end of the header main 1A of the second heat radiating panel 102 is obtained by projecting the outlet 1R.

Further, in the header main pipe 1A at one end of the first heat radiating panel 101, as shown in FIG. 3A, an insertion pipe 1B for flow conversion from the lower surface of the upper end closing plate 1F to the lower end surface of the lowermost weft pipe 2A. The supply water from the supply port 1S descends in the insertion tube 1B and is sprayed to the outer periphery of the insertion tube 1B from the gap h4 (standard: 2 mm) between the lower end closing plate 1F and the insertion tube 1B. Thus, the outer peripheral area of the insertion pipe 1B in the header main pipe 1A is raised.

The upper end closing plate 1F is fused and joined, and the insertion tube 1C for flow conversion is lowered downward from the upper end closing plate 1F of the header main pipe 1A at the other end (left side) to the level of the lower surface of the lowermost weft pipe 2A. The lower end of the header main pipe 1A and the lower end of the header main pipe 1A at one end may be fused and closed with a closing plate 1F.

  In this case, the insertion tube 1C of the second heat radiation panel 102 has the same diameter and the same size as that of the first heat radiation panel 101. However, as shown in FIG. 4C, the insertion tube 1C is formed on the lower surface of the upper end closing plate 1F.

And an insertion hole H2 ′ is also formed at a position corresponding to the insertion hole H2 of the header main pipe 1A.

[Production of radiator He (Figs. 1 and 5)]
The heat radiator He may be formed by connecting and fixing the first heat radiation panel 101 and the second heat radiation panel 102 at the four corners of the top, bottom, left and right as shown in FIGS. 1 (A) and 1 (C). The header main pipe 1A at the other end of the panel 101 (left side in FIG. 1A) is directly below the upper end closing plate 1F, and is opposed to the insertion hole H2 ′ of the header main pipe 1A at the other end of the second heat radiation panel 102. , A communication pipe piece 1D fitting hole having the same diameter as that of the insertion hole H2 ′ is formed, and the communication pipe piece 1D is connected to the fitting hole of the first heat radiation panel 101 and the insertion pipe 1C of the second heat radiation panel 102. It is connected and fixed to the insertion hole H2.

Further, the connecting portions at the other three corners are integrated with each other between the opposing surfaces of the header main pipe 1A via the spacer pipe 1E.
In this case, the joining and fixing of the communication pipe piece 1D and the spacer pipe 1E can be applied by means of heat fusion, but typically, a primer for primer preparation (product number: PP7F) manufactured by Cemedine Co., Ltd. Is applied to the joint, and a one-component room temperature fast-curing adhesive, Super X NO. Implemented using 8088 white (trade name).

  In this case, as shown in FIG. 1C, when the gap gs between the header main pipes 1A is integrated with 4.5 mm as shown in FIG. 1C, the weft pipe 2A group of the first heat radiating panel 101 and the second heat radiating panel are integrated. The gap gp between the inner surfaces of the panel 102 and the weft pipe 2A group is 18.5 mm, and the heat radiator He is composed of two heat radiation panels 101 and 102 having the same shape in a multi-layer form, the total lateral length L1 is 1000 mm, the weft pipe The exposed length L2 of 2A is 946 mm, the front-rear width W1 is 58.5 mm, and the height including the supply port 1S and the discharge port 1R is 500 mm.

[Completed radiator]
If the obtained radiator is pumped and supplied with hot water (standard: 60 ° C.) or cooling water (standard: 14 ° C.) from the supply port 1S of the upper protruding pipe piece of the first heat radiating panel 101, as shown in FIG. The supply water flow f1 becomes a downward flow f2 in the flow converting insertion pipe 1B communicating with the supply port 1S, flows down the center of the right (one end) header main pipe 1A, and is inserted at the lower surface of the lowermost weft pipe 2A. From the lower end of the pipe 1B, the jet pipe flows into the header main pipe 1A to become the upflow f3 in the header main pipe 1A and the lateral flow f4 of the weft pipe 2A group, and the communicating pipe piece 1D from the upflow f5 in the header main pipe 1A at the other end (right side). Enters the second heat dissipating panel 102 in the second heat dissipating panel 102, and descends in the second heat dissipating panel 102 through the downflow F7 in the insertion pipe 1C → the upflow f8 in the header main pipe 1A → the crossflow f9 in the weft pipe 2A → right side (one end) Above the header main pipe 1A Flow f10 → to the circulating flow in the path of the exhaust flow f11.

Accordingly, each path of the all weft pipes 2A from the supply port 1S to the discharge port 1R has the same length, and the cross current fills and flows through the all weft pipes 2A. The second heat radiating panel 102 also has a substantially uniform heating or cooling heat generation effect.
The uppermost weft pipe 2A, in which air accumulation in the water flow path is likely to occur, is filled with simultaneous ascending flows f3 and f8 from the header main pipe 1A to suppress the air accumulation, and the discharge port 1S becomes the top of the radiator. Since it exists in the upper part, an air pocket does not arise in a radiator during operation of a radiator.

  The radiator He is thin with a front and rear thickness W1 of 58.5 mm, a height h1 as small as 451 mm, is horizontally long (1000 mm), and the distance (gp) between the panels of the two radiator panels is 18. 5mm multi-layer type, each weft pipe 2A is in the form of three integrated blocks 2 with a spacing of 5mm (g2) between each block, so that the flow between the two heat dissipating panels does not stagnate up and down. Demonstrate that the horizontal gap g2 (5mm) between the blocks 2 causes the turbulent flow of air between the two panels and the outside of the panels, and the interface air (boundary layer) on the weft pipe 2A surface Larger movement improves convective heat transfer to ambient air.

In addition, the heat radiator He of the present example is the result of a comparative heat generation test conducted at the Hokkaido Industrial Research Institute and the heat radiator of Conventional Example 2 (FIG. 7), which is currently evaluated as a high performance heat radiator. As for the heat radiator, the result of 51% increase in calorific value was obtained.
Therefore, if the heat radiator obtained in the embodiment of the present invention is arranged in a suspended form on the partition wall of the building and connected to the ceiling pipe, for example, no air accumulation occurs in the heat radiator He, that is, air venting maintenance is performed. It is possible to construct an unnecessary heating / cooling system with a large calorific value.
