[Background technology]

[0002] 2. Description of the Related Art Conventionally, as a radiation panel, there has been known a cooling and heating radiation panel having an upper header and a lower header facing each other vertically, and a plurality of water pipes connected to both headers.

[0003] In this type of radiation panel, in order to efficiently dissipate the radiant heat (radiation heat) from the cold and hot water flowing inside the water pipes to the front of the panel, a partition plate is provided in the header to make the flow of the cold and hot water uniform and suppress disruptions to the temperature distribution of the radiant heat (see, for example, Patent Documents 1 and 2).

[0004] The structure described in Patent Document 1 discloses a structure in which a partition plate is fitted into the center of a header, and the structure described in Patent Document 2 discloses a structure in which a partition plate is fixed inside the header. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2010-107151 A (see FIG. 10 in particular) [Patent Document 2] Registered Utility Model Publication No. 3025801 (see especially Fig. 1) Summary of the Invention [Problem to be solved by the invention]

[0006] However, the structures described in Patent Documents 1 and 2 all involve providing a partition plate within a pipe-shaped or rectangular cylindrical header, which means that it is difficult to provide a watertight partition plate at a specified position within the hollow portion of a long header, and there is a concern that the manufacturing costs of the radiant panel itself will increase.

[0007] The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a radiant panel and a manufacturing method for a radiant panel that makes it easy to install a partition member into a header, ensures watertightness, and reduces manufacturing costs. [Means for solving the problem]

[0008] In order to achieve the above object, the first invention is a radiation panel having an upper header and a lower header facing each other vertically, and a plurality of water pipes connected to the hollow parts of both the headers, Both of the headers have end partition members that separate the hollow portion from the outside, and at least one of the headers has a middle partition member that separates the middle portion of the hollow portion, and the end partition members and the middle partition members are The watertight packing is in close contact with the hollow portion and is formed to be slidable relative to the hollow portion. The partition member for the end portion is restricted in sliding by a vertical frame that connects the ends of both headers, the intermediate partition member is restricted in sliding movement by the end of the water pipe protruding into the hollow portion when the intermediate partition member is connected to the hollow portion; This is characterized by the above (Claim 1).

[0018] In this case, it is preferable that the step of arranging the partition member at a specified position includes a step of arranging the partition member by restricting sliding of the partition member with the vertical frame, and a step of arranging the partition member by restricting sliding of the partition member with the end of the water pipe that protrudes into the hollow portion when the partition member is connected to the hollow portion (see claim 6 ).

[0019] With this configuration, after the partition members having watertight packings are slidably inserted into the hollow portions of both headers, the upper and lower ends of the water pipes are inserted into the water pipe insertion holes provided on the opposing faces of both headers, and with the hollow portions of both headers blocked, both ends of both headers are connected with the vertical frames to assemble the radiant panel. Then, by applying water pressure to the hollow portions of both headers, the partition members slide within the hollow portions by the water pressure and are positioned in the specified position. In this case, the partition members for the ends on both ends of the header's hollow portions are positioned at both ends of the header with their sliding restricted by the vertical frames connecting the ends of both headers, and the intermediate partition member for the intermediate portion of the hollow portion is positioned in the intermediate portion of the header with its sliding restricted by the ends of the water pipes that protrude into the hollow portions when connected to the hollow portions (see claim 1). 6 ).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Hereinafter, the embodiment of the present invention will be described in detail with reference to the attached drawings. Here, the case where the radiant panel 1 according to the present invention is arranged along the wall surface of an indoor facility including a gymnasium, and is used for cooling and heating the indoor facility by circulating cold and hot water, which is a heat medium supplied from a heat source (not shown), inside the panel and radiating cold and hot air is described.

[0030] First Embodiment As shown in Figs. 1 and 2, the radiation panel 1 includes a pair of vertical frames 2 on the left and right, an upper frame 3 installed on the upper ends of the vertical frames 2, and a rectangular panel frame 5 formed of a lower frame 4 installed on the lower ends of the vertical frames 2, a pair of upper headers 6a and lower headers 6b facing each other vertically in the panel frame 5, a plurality of parallel heat sinks 10 (for example, 12 rows) connected to the hollow parts, i.e., the communication passages 6c of the upper headers 6a and lower headers 6b via water pipes 11, and a ball-proof part 20 attached to the heat sinks 10. The upper end, lower end, and middle part of the back surface of the heat sink 10 are held by horizontal bars (not shown) with a hollow rectangular cross section fixed to the vertical frames 2. The upper and lower ends of the plurality of heat sinks 10 are connected and held by a holding plate (not shown). The vertical frames 2, the upper frame 3, and the lower frame 4 are formed of extruded shapes made of aluminum alloy. Here, the case where 12 rows of heat sinks 10 are arranged has been described, but the number of heat sinks 10 can be set arbitrarily in accordance with the width dimension of the radiating panel 1.

[0031] A heat insulating material 9 having a heat reflecting plate 8 on its surface is attached to the rear surface of the panel frame 5. A gutter-shaped drain 70 fixed to both vertical frames 2 and the heat insulating material 9 is disposed below the heat sink 10 on the rear surface side within the panel frame 5. Drain pipes 71 are connected to two points in the center of the drain 70 (see FIG. 1).

[0032] A pair of end partition members 7A (hereinafter referred to as end partition members 7A) that separate the inside of the upper header 6a from the outside are disposed in the communication passage 6c of the upper header 6a. The end partition members 7A have watertight packing 7e, and the watertight packing 7e separates the inside of the upper header 6a from the outside in a watertight state. Air vent valves 53 are attached to two locations in the longitudinal direction of the upper header 6a.

[0033] In the communication passage 6c of the lower header 6b, a pair of end partition members 7A that separate the lower header 6b from the outside and an intermediate partition member 7B (hereinafter referred to as intermediate partition member 7B) that separates the intermediate portion of the communication passage 6c are arranged. The end partition member 7A and the intermediate partition member 7B have watertight packing 7e as described above, and the watertight packing 7e separates the inside of the lower header 6b from the outside in a watertight state and also separates the intermediate portion of the lower header 6b in a watertight state. In this case, the intermediate partition member 7B separates the communication passage 6c of the lower header 6b into an inlet side space 6d connected to the supply pipe 51 and an outlet side space 6e connected to the drain pipe 52. An air vent valve 53 is attached to each of the supply pipe 51 and the discharge pipe 52.

[0034] The end partition member 7A and the intermediate partition member 7B are formed to have the same structure. That is, as shown in Figures 3A, 4A, and 7, the end partition member 7A and the intermediate partition member 7B are divided into a front member 7a and a rear member 7b along the longitudinal direction of the hollow portion, i.e., the communication passage 6c, of the upper header 6a and the lower header 6b, and the front member 7a and the rear member 7b are connected by a fastening screw 7c, which is a fastening member, and the watertight packing 7e is sandwiched between the front member 7a and the rear member 7b.

[0035] In this case, the front member 7a is provided with a circumferential groove 7a2 for inserting a watertight packing 7e on the rear end side of the cylindrical base 7a1, and a screw hole 7d into which the fastening screw 7c screws is provided on the rear end surface on which the circumferential groove 7a2 is provided. The rear member 7b is formed of a disk having approximately the same outer diameter as the outer diameter of the cylindrical base 7a1 of the front member 7a, and is provided with a mounting hole 7g in the center through which the fastening screw 7c can pass. Both the front member 7a and the rear member 7b are formed of aluminum members.

[0036] The watertight packing 7e, which is inserted into the circumferential groove 7a2 and sandwiched between the front member 7a and the rear member 7b, is formed of a U-packing having a U-shaped cross section and made of synthetic rubber such as polyurethane rubber, nitrile rubber, fluororubber, etc. The watertight packing 7e may be formed of an O-ring 7f instead of the U-packing (see FIG. 7).

[0037] 10 to 12, the heat sink 10 is formed of an aluminum alloy extruded member that is integrated with water pipes 11 communicating with the upper header 6a and the lower header 6b, a straight base 12 extending from the longitudinal side surface of the water pipes 11 substantially perpendicular to the water pipes 11, and a plurality of heat sink fins 13 (e.g., eight on each side) that protrude parallel to each other from both side surfaces of the straight base 12. The number of heat sink fins 13 does not need to be eight on each side, and may be any number.

[0038] In this case, the flow passage of the heat medium in the water tube 11 is provided with a pair of ribs 11a, 11b protruding into the flow passage from an extension of the straight base portion 12, and a pair of ribs 11c, 11d protruding into the flow passage in a direction perpendicular to the pair of ribs 11a, 11b; 11c, 11d. By providing the two pairs of ribs 11a, 11b; 11c, 11d, which are positioned perpendicular to each other, in the flow passage of the water tube 11, the heat transfer performance of the heat medium flowing in the flow passage of the water tube 11 can be improved.

[0039] In addition, a convex arc-shaped bulging protrusion 12a is provided at the tip of the straight base 12. The heat dissipation fins 13 are formed slightly thinner than the straight base 12, and the tip of each heat dissipation fin 13 is formed thick. In addition, the connecting portion 14 between the heat dissipation fin 13 closest to the pipe portion 11 and the straight base 12 is thick, and a narrow taper is provided from the straight base 12 to the heat dissipation fin 13. In this way, the connecting portion 14 between the heat dissipation fin 13 closest to the pipe portion 11 and the straight base 12 is made thicker than the connecting portions between the other heat dissipation fins 13 and the straight base 12, and a narrow taper is provided toward the heat dissipation fin 13. Therefore, the water tube side of the heat dissipation fin 13 closest to the pipe portion 11 has more open space than the other heat dissipation fins 13, so the convection heat transfer coefficient is larger than the others, and the connecting portion 14 can be made thicker for balance, improving heat conduction. Furthermore, by making the tip of each heat dissipating fin 13 thicker, more heat can be transferred from the tip, which has a higher convection heat transfer coefficient than other portions.

[0040] At two connecting portions between the tip-side heat dissipation fin 13 and the second heat dissipation fin 13 on the water pipe 11 side and the straight base 12, screw pockets 15a and 15b having a narrow arc-shaped cross section are provided at positions symmetrical with respect to the straight base 12. A holding plate (not shown) that connects and holds the upper and lower ends of the heat dissipation body 10 is fixed by screws (not shown) that screw into the screw pockets 15a and 15b.

[0041] Also, insulating rubber 21, which is an insulating member, is fitted into bulging protrusion 12a formed on the tip of straight base 12, and ball-blocking part 20 is fitted into insulating rubber 21. In this case, insulating rubber 21 is formed in a narrow arc shape that can be fitted into convex arc-shaped bulging protrusion 12a, as shown in Fig. 11 .

[0042] The ball-blocking part 20 is formed in a hollow cylindrical shape having a concave arc-shaped fitting part 20a that can be fitted into the convex arc-shaped outer peripheral surface of the heat-insulating rubber 21, and a reinforcing rib 20b located on an extension line of the straight base part 12 of the heat sink 10. Note that it is sufficient that the reinforcing rib 20b is provided at least on an extension line of the straight base part 12, and further reinforcing ribs may be added. The ball-blocking part 20 is formed from an extruded shape made of an aluminum alloy. By forming the ball-blocking part 20 in a hollow cylindrical shape having the reinforcing rib 20b in this way, the ball-blocking part 20 can be made lightweight and strong.

[0043] Further, notched steps 16 are provided at the upper and lower ends of the water tubes 11 of the heat sink 10 so that the upper header 6a and the lower header 6b can be accommodated therein, and the water tubes 11 are formed to protrude from the horizontal portions of the notched steps 16. In this case, the notched steps 16 are provided at positions away from the water tubes 11 of the straight base portion 12 connected to the water tubes 11. Further, the upper and lower ends of the water tubes 11 are cut to a length that protrudes into the communicating passages 6c provided in the upper header 6a and the lower header 6b, and narrow tapers are provided at the open ends.

[0044] The upper header 6a and the lower header 6b have connecting passages 6c with a circular cross section, and the sides facing the upper header 6a and the lower header 6b are formed from aluminum extruded profiles with flat rectangular cross sections, and water pipe insertion holes 60 into which water pipes 11 of the heat sink 10 can be inserted are provided on the facing surfaces of the upper header 6a and the lower header 6b, i.e., on the bottom of the upper header 6a and the top of the lower header 6b.

[0045] The water pipe insertion hole 60 is formed to fit the dimensions of the annular header packing 40, and is formed in a stepped shape having a large diameter hole portion 61 into which the header packing 40 is fitted and a small diameter hole portion 62 into which the water pipe 11 is inserted, as shown in Fig. 8. In addition, both side surfaces adjacent to the opposing surfaces of the upper header 6a and the lower header 6b are narrowly tapered toward the opposing surfaces, and an outer locking groove 6f is provided at the base end of this narrow taper (see Figs. 6 and 8). The outer locking groove 6f is formed in a narrow opening shape with a recess on the opposing surface side. A packing gland 30, which will be described later, is engaged with this outer locking groove 6f.

[0046] As shown in Figures 6 and 8, the packing gland 30 comprises a horizontal piece 31 that covers the opposing surfaces of the upper header 6a and the lower header 6b except for the water pipe insertion hole 60, and leg pieces 32 that are bent from both side edges of the horizontal piece 31 to cover the side surfaces adjacent to the opposing surfaces, and the locking claws 33 provided at the tips of the leg pieces 32 are formed so as to be able to engage with the outer locking grooves 6f. The packing gland 30 is formed from an extruded aluminum material, and the horizontal piece 31 is provided with a through hole 34 that communicates with the water pipe insertion hole 60, and the leg pieces 32 are formed in an expanding tapered shape corresponding to the narrow tapered side surfaces of the upper header 6a and the lower header 6b. The locking claws 33 formed at the tips of the leg pieces 32 are bent into a hook shape so as to reliably engage with the recesses of the outer locking grooves 6f.

[0047] The header packing 40 is formed of a U-packing made of the same material as the watertight packing 7e. The header packing 40 is attached by inserting the header packing 40 into the large diameter hole portion 61 of the water pipe insertion hole 60 of the upper header 6a and the lower header 6b, and then engaging the locking claws 33 of the packing retainer 30 with the outer locking grooves 6f of the upper header 6a and the lower header 6b so as to cover the outer surface of the header packing 40, thereby fixing the header packing 40 to the large diameter hole portion 61 of the water pipe insertion hole 60. This prevents the header packing 40 from shifting out of position. Therefore, the header packing 40 inserted into the water pipe insertion hole 60 can be easily and reliably held without using a fixing member, thereby improving the watertightness of the radiation panel itself.

[0048] As described above, the header gasket 40 is inserted into the water tube insertion holes 60 of the upper header 6a and the lower header 6b, and the header gasket 40 is fixed to the large diameter hole portion 61 of the water tube insertion hole 60 by the gasket holder 30. Then, the water tubes 11 of the heat sink 10 are inserted through the through holes 34 of the gasket holder 30 and into the water tube insertion holes 60 provided in the upper header 6a and the lower header 6b, thereby connecting (joining) the upper and lower ends of the water tubes 11 to the upper header 6a and the lower header 6b in a watertight state.

[0049] After connecting (joining) the upper and lower ends of the water pipes 11 to the upper header 6a and the lower header 6b, both ends of the communication passages 6c of the upper header 6a and the lower header 6b are blocked with the vertical frame 2 that constitutes the radiant panel 1, and the fixing screws 2a that pass through the vertical frame 2 are screwed into the upper header 6a and the lower header 6b to connect the upper header 6a and the lower header 6b.

[0050] In the above description, the leg pieces 32 of the packing gland 30 are formed in an expanding tapered shape, but the engagement form between the packing gland 30 and the outer locking grooves 6f of the upper header 6a and the lower header 6b is not necessarily limited to this structure. For example, as shown in Fig. 9(a), a packing gland 30A having leg pieces 32A bent perpendicularly from both side edges of the horizontal piece 31 may be engaged with the outer locking grooves 6f of the upper header 6a and the lower header 6b similar to the above. Also, as shown in Fig. 9(b), the locking claws 33 of the packing gland 30A may be engaged with the outer locking grooves 6f of the upper header 6a and the lower header 6b whose side surfaces adjacent to the opposing surfaces have side surfaces perpendicular to the opposing surfaces. Alternatively, as shown in FIG. 9(c), a packing gland 30B having short leg pieces 32B bent perpendicularly from both side edges of a horizontal piece 31 may be engaged with the outer locking grooves 6f of an upper header 6a and a lower header 6b, whose side surfaces adjacent to the opposing surface have side surfaces perpendicular to the opposing surface.

[0051] In the above description, the packing gland 30, 30A, 30B is engaged with the outer locking groove 6f of the upper header 6a and the lower header 6b, but the plate-shaped packing gland 30C may be engaged with the inner locking groove 6g provided in the upper header 6a and the lower header 6b. That is, as shown in Fig. 9(d), both side edges of the plate-shaped packing gland 30C may be engaged with the inner locking groove 6g of the narrow opening 6h provided on the opposing surfaces of the upper header 6a and the lower header 6b. The packing gland 30C is formed of an extruded aluminum material, and has a through hole 34 communicating with the water pipe insertion hole 60.

[0052] Next, a manufacturing procedure for the radiation panel will be described. Here, a case where the packing gland 30 is used will be described. Four end partition members 7A having watertight packings and an intermediate partition member 7B having watertight packing 7e are prepared in advance. First, the two end partition members 7A are slidably inserted into the hollow portion of the upper header 6a, i.e., the communicating passage 6c at both ends in the longitudinal direction, the intermediate partition member 7B is slidably inserted into the middle portion of the communicating passage 6c of the lower header 6b, and the two end partition members 7A are slidably inserted into the communicating passage 6c of the lower header 6b at both ends in the longitudinal direction.

[0053] In addition, when inserting the intermediate partition member 7B into the middle part of the communicating passage 6c, the intermediate partition member 7B inserted into one opening end of the lower header 6b can be set to a predetermined position in the communicating passage 6c by using a push rod or the like having a stopper such as a flange at a predetermined length.

[0054] After inserting the end partition member 7A and the intermediate partition member 7B into the communicating passages 6c of the upper header 6a and the lower header 6b as described above, the header gasket 40 is inserted into the water pipe insertion hole 60 provided on the opposing surfaces of the upper header 6a and the lower header 6b, and the locking claws 33 of the gasket holder 30 are engaged with the outer locking grooves 6f of the upper header 6a and the lower header 6b so as to cover the outer surface of the header gasket 40, thereby fixing the header gasket 40 to the large diameter hole portion 61 of the water pipe insertion hole 60.

[0055] With the header gasket 40 fixed in the water tube insertion hole 60, the water tube 11 of the heat sink 10 is inserted through the through hole 34 of the gasket retainer 30 into the water tube insertion hole 60 provided in the upper header 6a and the lower header 6b, thereby connecting (joining) the upper and lower ends of the water tube 11 to the upper header 6a and the lower header 6b.

[0056] Next, with the communication passages 6c of the upper header 6a and the lower header 6b blocked, the fixing screws 2a that pass through the vertical frame 2 are screwed into the upper header 6a and the lower header 6b to connect the upper header 6a and the lower header 6b, and the radiant panel 1 is assembled in this state (see FIG. 13(a)). In this state, there is a slight gap S1 between the end partition member 7A and the vertical frame 2 (see FIG. 13(b)), and there is a gap S2 between the middle partition member 7B and the water pipe 11 protruding into the communication passage 6c (see FIG. 13(c)).

[0057] With the radiation panel 1 assembled as described above, the end partition member 7A and the intermediate partition member 7B are arranged in a predetermined position by the water pressure of the water flowing into the inlet side space 6d of the lower header 6b from the supply pipe 51 connected to the lower header 6b and the inlet side space 6d. Specifically, the water flowing into the inlet side space 6d flows through the water pipes 11 of the six rows of radiators 10 that communicate with the inlet side space 6d and flows into the upper header 6a. The water flowing into the upper header 6a flows through the water pipes 11 of the six rows of radiators 10 that communicate with the outlet side space 6e and flows into the outlet side space 6e of the lower header 6b. In this way, water pressure is applied to the communication passage 6c of the upper header 6a and the lower header 6b, and the end partition member 7A is arranged with the sliding restricted by the vertical frame 2, and the intermediate partition member 7B is arranged with the sliding restricted by the end of the water pipe 11 protruding into the communication passage 6c (see FIG. 1). After the radiation panel 1 is assembled, the timing for causing water to flow into the lower header 6b may be set to coincide with the time when the radiation panel 1 is in operation.

[0058] An example of the case where the radiation panel 1 manufactured as described above is used in a cooling and heating system will be described. In the cooling and heating system, during cooling, for example, hot and cold water of 12°C±5°C, which is supplied from a heat source and is made of, for example, antifreeze (antifreeze with a concentration of 23 to 40% diluted with water, whose main component is ethylene glycol and contains a rust inhibitor) or pure water, flows into the inlet side space 6d of the lower header 6b of the radiation panel 1, flows through the water pipes 11 of the six rows of heat radiators 10 that communicate with the inlet side space 6d, and flows into the upper header 6a. The hot and cold water that has flowed into the upper header 6a flows through the water pipes 11 of the six rows of heat radiators 10 that communicate with the outlet side space 6e, and flows into the outlet side space 6e of the lower header 6b.

[0059] When hot or cold water flows through the water pipes 11 of the radiator 10 via the inlet space 6d of the lower header 6b of the radiant panel 1, air in the water is removed by the air vent valve 53 provided in the supply piping 51, air in the water that flows into the upper header 6a is removed by the air vent valve 53 provided in the upper header 6a, and air in the water that flows from the outlet space 6e of the lower header 6b to the discharge piping 52 is removed by the air vent valve 53 provided in the discharge piping 52.

[0060] Therefore, the straight base 12 and the multiple heat dissipation fins 13 amplify convection in the radiant heat transfer from the water pipes 11 through which the cold and hot water from which the air has been removed flows, and the heat can be dissipated to the front surface of the radiant panel 1. The heat loss of the radiant heat dissipated to the rear side from the water pipes 11 located on the rear side can be suppressed by the heat reflector 8. This forms a low-temperature air layer between the floor surface and the height of the radiant panel 1, for example, 2.5 m.

[0061] When the radiant panel 1 is used for heating, antifreeze or pure water supplied from a heat source is heated to a predetermined temperature, for example 40°C, using a heat exchanger (not shown) to produce hot water, which can be used for heating by flowing the hot water into the lower header 6b of the radiant panel 1 in the same manner as described above.

[0062] <Second embodiment> In the first embodiment, one intermediate partition member 7B is disposed in the communication passage 6c of the lower header 6b, but the radiation panel according to the present invention is not limited to this. A plurality of intermediate partition members 7B may be disposed in the upper header 6a and the lower header 6b to change the overall flow path length.

[0063] For example, as shown in Fig. 14, one intermediate partition member 7B defined by the water tubes 11 of the heat dissipation body 10 in the seventh row from the right in Fig. 14 is disposed in the center of the communication passage 6c of the upper header 6a, dividing the communication passage 6c of the upper header 6a into a right space 6i and a left space 6j. Meanwhile, two intermediate partition members 7B defined by the water tubes 11 of the heat dissipation body 10 in the fourth and tenth rows from the right in Fig. 14 are disposed in the communication passage 6c of the lower header 6b, dividing the communication passage 6c of the lower header 6b into an intermediate space 6k between an inlet space 6d and an outlet space 6e.

[0064] With the above-mentioned configuration, for example, hot and cold water flows into the inlet space 6d through the supply pipe 51, flows through the water pipes 11 of the radiators 10 in rows 1 to 3 that communicate with the inlet space 6d, and flows into the right space 6i in the upper header 6a. The hot and cold water that flows into the right space 6i flows through the water pipes 11 of the radiators 10 in rows 4 to 6 and flows into the intermediate space 6k in the lower header 6b. The hot and cold water that flows into the intermediate space 6k flows through the water pipes 11 of the radiators 10 in rows 7 to 9 and flows into the left space 6j in the upper header 6a. The hot and cold water that flows into the left space 6j of the upper header 6a flows through the water pipes 11 of the radiators 10 in rows 10 to 12 that communicate with the outlet space 6e, and flows into the outlet space 6e of the lower header 6b.

[0065] As described above, the flow path length of the cold / hot water can be changed by making the flow of the cold / hot water meander. When the cold / hot water flows through the lower header 6b and the upper header 6a of the radiant panel 1, air in the water is removed by the supply pipe 51, the discharge pipe 52, and the air vent valve 53 provided in the upper header 6a.

[0066] In the second embodiment, other parts are the same as those in the first embodiment, so the same parts are denoted by the same reference numerals and the description thereof will be omitted. Also, the second embodiment is an example of a case where a plurality of intermediate partition members 7B are used, and the flow path length different from the above can be arbitrarily changed by arbitrarily combining the number of intermediate partition members 7B and the number of rows of heat sinks 10.

[0067] According to the embodiment of the radiation panel 1 configured as described above, the end partition member 7A and the intermediate partition member 7B having watertight gasket 7e can be slid and positioned within the connecting passage 6c, which is the hollow portion of the upper header 6a and the lower header 6b.This makes it possible to easily and reliably attach the end partition member 7A and the intermediate partition member 7B to the upper header 6a and the lower header 6b while maintaining watertightness, and also reduces manufacturing costs.

[0068] In addition, since the watertight gasket 7e is attached in a state where it is sandwiched between the front member 7a and the rear member 7b, the watertight gasket 7e can be easily and securely attached to the end partition member 7A and the intermediate partition member 7B, thereby maintaining the watertightness of the end partition member 7A and the intermediate partition member 7B.

[0069] According to the manufacturing method of the radiation panel of the above embodiment, the end partition member 7A and the intermediate partition member 7B are slidably inserted into the communication passage 6c of the upper header 6a and the lower header 6b, the upper and lower ends of the water pipe 11 are inserted into the water pipe insertion hole 60 provided in both headers 6a and 6b through the header packing 40, and both ends of both headers 6a and 6b are connected by the vertical frame 2 to assemble the radiation panel. Then, water pressure is applied to the communication passage 6c of both headers 6a and 6b to place the end partition member 7A in a position regulated by the vertical frame 2, and the intermediate partition member 7B is placed in a predetermined position regulated by the water pipe 11 protruding into the communication passage 6c. Therefore, the end partition member 7A and the intermediate partition member 7B can be easily and reliably attached to both headers 6a and 6b while maintaining watertightness, and the manufacturing cost can be reduced.

[0070] In the above embodiment, the case where the intermediate partition member 7B is placed in the communicating passage 6c of the lower header 6b is described. However, a structure in which an intermediate partition member 7B is placed in the communicating passage 6c of the upper header 6a, a supply pipe 51 is connected to the inlet side space 6d partitioned by the intermediate partition member 7B, and a discharge pipe 52 is connected to the outlet side space 6e may also be used.
