Description

Radiation panel device

The present invention relates to a radiation panel device that performs radiation heating and radiation cooling.

Conventionally, a radiation panel device using a liquid such as oil or antifreeze as a heat medium is known. In this type of radiant panel device, each panel is provided with radiation by circulating a heat medium between a plurality of panels and a separately installed heat source, and a living room or the like is provided by radiant heating or radiant cooling by the panel. It is possible to perform air conditioning. For example, Patent Document 1 discloses a radiant panel device in which a heat medium flow pipe for flowing a heat medium is provided inside the panel, and the heat medium is circulated through the heat medium flow pipe to radiate radiant heat from the panel. ing.

JP 2010-243127 A

In this type of radiant panel device, it is not assumed that the panels are swung in the first place, the direction of the wind flowing between the panels is changed, and the line of sight is between the opposite side and the near side of the panel. Can't block or block. Actually, the radiation panel device described in Patent Document 1 does not have a configuration for swinging the panel, and does not have a configuration of piping that enables the panel to swing.

Therefore, the present invention has been made to solve such a problem, and provides a radiation panel device capable of swinging a plurality of panels to which radiation ability is imparted by circulation of a heat medium. With the goal.

In order to solve the above problems, a radiation panel device according to the present invention has a plurality of long and flat panels and a passage through which a heat medium circulates between the heat source and a portion accommodated in the panel. A heat medium flow pipe that imparts radiation to the panel by forming a bridge, and a bridge having a plurality of panels arranged at a predetermined interval and having a through hole at a position facing one end of the panel And a rotating mechanism that has an axial tube passed through the through-hole, is provided from one end of the panel to the bridge, and supports the panel so as to be rotatable about the axis of the axial tube with respect to the bridge, The heat medium flow pipe is folded back in the panel and forms a reciprocating passage route with one end side of the panel as an entrance and exit, and is connected to the end of the storage section and passes through the shaft pipe. The axis of the axial tube A pair of extending portions protruding from symmetrical positions, and a connecting portion connected to the extending portion of another panel, which is a tip portion of the extending portion protruding from each of the plurality of panels. Is characterized in that, among the connecting portions of the extending portions protruding from other panels, the connecting portion of the extending portion protruding from the same side with respect to the axis of the axial tube is connected.

The above radiant panel device includes a bridge for holding a plurality of panels, and the bridge has a through hole at a position facing one end of the panel. A shaft tube of a rotating mechanism is passed through the through hole, and the rotating mechanism supports one end of the panel so as to be rotatable around the axis of the shaft tube with respect to the bridge. The heat medium flow pipe has a pair of extending portions protruding from the panel, and the pair of extending portions protrudes from a symmetrical position with respect to the axis of the shaft tube by passing through the through hole through the inside of the shaft tube. . Therefore, when the panel is swung around the axis of the shaft tube, the pair of extending portions move around the axis of the shaft tube while maintaining the mutual positional relationship within the shaft tube. As a result, it is possible to prevent the distance between the pair of extending portions from changing with the swinging of the panel or the pair of extending portions from being separated from the axis, and the position of the pair of extending portions with respect to the axis The relationship is maintained even if the panel is swung.

Furthermore, in this radiant panel device, among the extending portions that protrude from each of the plurality of panels, the extending portions that protrude from the same side with respect to the axis line are connected to each other via a connecting portion. That is, the extending portions protruding from the same side are connected to each rotation mechanism that rotatably supports each panel, thereby forming a series piping system of heat medium flow tubes between the panels. Therefore, the interval between the extending portions connected to each other coincides with the interval between the axes of the axial tubes through which both extending portions pass, and the panel swings while maintaining this interval. . As a result, since it is possible to avoid the interval between the extending portions connected to each other from expanding or narrowing due to the swinging of the panel, it is possible to prevent the panel from rotating poorly and to swing the panel smoothly. Further, since the pair of extending portions of the heat medium flow tube passes through the shaft tube, the movement of the heat medium flow tube due to the rocking of the panel is suppressed, so the heat medium during the rocking of the panel The load on the flow tube can be reduced, and the heat medium flow tube can be kept warm in the shaft tube.

Further, it is preferable that the rotating mechanism is held in a state in which movement in the direction of approaching and separating from the axis of each extending portion in the shaft tube is restricted. In this configuration, since the pair of extending portions are constrained in a state of being symmetric with respect to the axis line in the shaft tube, even if the panel is swung, the positional relationship between the pair of extending portions is not displaced in the shaft tube. It becomes difficult to occur. As a result, the smooth swinging state of the panel can be stably maintained.

Further, the shaft tube is fixed to one end portion of the panel and is rotatably fitted in the through hole so as to protrude from the bridge. A portion of the shaft tube protruding from the bridge is on the side of the shaft tube. It is preferable to further have an engaging portion that is rotatably engaged with the bridge. The loose fit is intended to be fitted in a state where there is play. In this configuration, the shaft tube is fixed to one end of the panel, and the shaft tube rotates relative to the bridge together with the panel. As a result, the pair of extending portions of the heat medium flow tube constrained in the shaft tube also rocks with the rocking of the panel, and the twist of the heat medium flow tube due to the rocking of the panel can be reduced, It is effective in making the panel swing more smoothly.

Furthermore, it is preferable that the rotating mechanism further includes a buffer member that reduces frictional resistance generated between the bridge and the engaging portion as the engaging portion rotates. In this configuration, since the frictional resistance between the bridge and the engaging portion generated along with the swing of the panel is relieved, the panel can be swung more smoothly.

Moreover, it is preferable that the inner periphery of the shaft tube has a non-circular cross-sectional shape in a direction orthogonal to the axis. In this configuration, by making the cross-sectional shape of the shaft tube non-circular, the rotational position with respect to the bridge when the shaft tube is attached is determined, and the panel can be easily positioned with respect to the bridge.

It is preferable that a link mechanism for connecting a plurality of rotation mechanisms or panels is further provided. In this configuration, a plurality of rotation mechanisms that rotatably support the plurality of panels are connected by the link mechanism. For this reason, when one panel is rocked, the other panel rocks by the same amount as the one panel as the rotation mechanism rotates and the link mechanism moves. As a result, the interval between the extending portions is more strictly maintained, and rotation failure can be further suppressed.

In addition, the link mechanism is connected to a plurality of rotation mechanisms, and is provided with a plurality of connection brackets that swing integrally with the shaft tube around the axis, and is provided rotatably with respect to the connection bracket, and between adjacent connection brackets. And a plate extending over the plate. In this configuration, since the angles of the panels with respect to the extending direction of the plates can be made the same, the panels can be swung more accurately in the same direction.

In addition, a plurality of series piping systems formed by connecting a plurality of heat medium flow pipes to each other at the connection portion are provided, and the heat medium is distributed to each of the plurality of series piping systems between the heat source and the series piping system. And a parallel merging unit that aggregates the heat medium discharged from each of the plurality of serial piping systems between the heat source and the serial piping system, and the parallel distributing unit and the parallel merging unit are: It is preferable that the panel can be swung up and down as the panel rotates. Each series piping system may be slightly twisted around the axis of the heat medium flow pipe as the panel swings. In this radiation panel device, the parallel distribution unit and the parallel junction unit are allowed to swing. As a result, twisting of the heat medium flow pipe is allowed, and thus it is possible to suppress the occurrence of defective rotation of the panel due to the application of resistance to the twist of the heat medium flow pipe.

According to the present invention, it is possible to swing a plurality of panels to which radiation is imparted by circulation of the heat medium.

The bridge 3 holds a plurality of panels 4 in an upright state in a state of being arranged in a horizontal direction at a predetermined interval. The predetermined interval may be a width that does not interfere with each other when the plurality of panels 4 are swung. Further, the predetermined interval includes the number of panels 4, the size and height of the room, or the required performance. It can be determined accordingly. The bridge 3 is also referred to as an “upper frame”.

In addition, although illustration is abbreviate | omitted, the reinforcement member is arrange | positioned so that bridge | bridging 3 may straddle a pair of rib wall 3b, and the support plate 3a is bolted to the reinforcement member.

The support plate 3a has a central portion 3d sandwiched between a pair of rib walls 3b and a pair of flange portions 3e projecting outward from the pair of rib walls 3b. In the central portion 3d, a through hole 3c is provided at a position facing the upper end portion (one end portion) 4a of each of the plurality of panels 4. A shaft tube 17 of a rotation mechanism 25 that supports the panel 4 is passed through the through hole 3c, and the panel 4 is rotatably attached to the support plate 3a via the rotation mechanism 25.

The panel 4 is formed by covering both ends of a long cylindrical member extending in the vertical direction and having a flat cross section with caps, for example, by extruding metal. The material of the panel 4 is not particularly limited, but it is preferable that the panel 4 is made of aluminum because the weight can be reduced and the panel 4 can be easily swung. Hereinafter, the direction in which the flat cross-sectional shape of the panel 4 extends in the horizontal direction is referred to as “the width direction of the panel 4”, and the horizontal direction perpendicular to the width direction is referred to as “the thickness direction of the panel 4”.

The cross-sectional shape of the outer wall 50 of the panel 4 is a substantially convex lens shape (see FIG. 4B), and a pair of left and right tip portions 50x that taper toward the outer side in the width direction and the left and right tip portions 50x are connected to each other. And a pair of flat plate portions 50y. The pair of flat plate portions 50y are arranged substantially in parallel, and a predetermined gap into which the shaft tube 17 of the rotation mechanism 25 is inserted is formed between the flat plate portions 50y.

A plurality of fins 50c protruding in a wave shape are provided on the outer surface of the tip portion 50x in order to widen the heat transfer area to the outside air. The plurality of fins 50 c extend in the longitudinal direction of the panel 4, that is, in the vertical direction in the state where the panel 4 is erected, and the condensed water generated on the surface of the panel 4 during cooling is directed toward the condensed water receiving member 6. It also has a function of guiding downward. Further, a fastening hole 50h into which the screw 31a is screwed is formed in the pointed end part 50x, and the upper end (one end part) 4a of the panel 4 and the screw 31a are screwed into the fastening hole 50h. The cap 30 is fixed to the lower end 4b.

A part of the heat medium flow pipe 5 is accommodated in the panel 4. As shown in FIGS. 2 and 4, the heat medium flow pipe 5 is substantially U-shaped, and a portion inserted into the panel 4 is bent and folded on the lower end (the other end) side of the panel 4. Thus, the

storage portions

5a and 5b form a reciprocating passage route having the upper end (one end portion) side as an entrance. Of the

accommodating portions

5a, 5b, and 5g, the portion that forms the passage through which the heat medium flows downward is the forward-side accommodating portion 5a, and the portion that forms the passage through which the heat medium flows upward is the return-side accommodating portion. 5b, and the part that communicates the forward path side accommodating portion 5a and the return path side accommodating portion 5b is the folded portion 5g.

The heat medium flow pipe 5 is made of, for example, a resin pipe having an inner diameter of about 7 mm. By using the resin-made heat medium flow pipe 5 in this way, the flexibility is good, the heat medium flow pipe 5 can be bent to a small radius, and the processing of the heat medium flow pipes 5 and the assembly work to the panel 4 can be easily performed. Further, by making the heat medium flow pipe 5 made of resin, twisting and movement accompanying the swing of the panel 4 are allowed, and the load on the heat medium flow pipe 5 when the panel 4 is swung is reduced. be able to. In the present embodiment, a cross-linked polyethylene pipe is used as the resin pipe, but it is also possible to adopt a polybuden or polyolefin resin material.

Guide portions 50d for holding the heat medium flow pipes 5 are formed inside the respective tip portions 50x of the panel 4, and guide members 51 are fitted at positions facing the respective guide portions 50d. . The guide part 50d and the guide member 51 are each semicircular, and the guide part 50d and the guide member 51 are combined to form a space having a circular cross section, and the forward path of the heat medium flow pipe 5 inserted into the space. The side accommodating part 5a or the return path side accommodating part 5b is held so as to be sandwiched.

The guide member 51 does not reach the lower end of the panel 4, and the forward path side accommodating portion 5a and the return path side accommodating portion 5b of the heat medium flow pipe 5 are connected to each other below the guide member 51 through a curved path. A folded portion 5g is disposed. Further, the guide member 51 does not reach the upper end of the panel 4, and there is a space S 1 in which the forward path side accommodating part 5 a and the return path side accommodating part 5 b are gathered closer to the center above the guide member 51. .

The heat medium flow pipe 5 collected nearer to the center in the space S1 passes through the shaft pipe 17 of the rotation mechanism 25 and passes through the cap 30 attached to the upper end 4a of the panel 4 and the support plate 3a of the bridge 3. Projecting above the bridge 3. In the heat medium flow pipe 5, the portions protruding from the upper end of the panel 4 are extending

portions

5 c and 5 d, and in particular, the side communicating with the forward path side accommodating portion 5 a is the forward path side extending portion 5 c and the return path side accommodating portion. The side that communicates with 5b is a return path extending portion 5d.

In the space S 1, the region from the lower end of the shaft tube 17 to the guide member 51 is a region that does not restrain the heat medium flow tube 5 and can absorb the twist of the heat medium flow tube 5 due to the swinging of the panel 4. It has become a part. The height H of this region, that is, the distance in the vertical direction from the guide member 51 to the lower end of the shaft tube 17 is at least three times the diameter of the heat medium flow tube 5, particularly preferably about 5 to 15 times. If it has height of this, the absorption effect of the twist of the heat-medium distribution pipe | tube 5 can be improved further.

The cap 30 attached to the upper end 4a of the panel 4 is a plate shaped like the outer periphery of the panel 4 as shown in FIG. 6, and is attached to the outer wall 50 so as to cover the opening of the upper end 4a. The cap 30 is made of a resin whose main component is, for example, ASA (acrylonitrile-styrene-acrylate) or AES (acrylonitrile-ethylenepropylene diene-styrene), and suppresses heat transfer between the panel 4 and the bridge 3. It has a function to do. A through hole 30b having a shape corresponding to the outer shape of the shaft tube 17 is formed in the center of the cap 30, and the shaft tube 17 is fitted into the through hole 30b.

As shown in FIGS. 4 to 7, the rotation mechanism 25 that supports the panel 4 is passed through the through hole 3 c of the bridge 3, and the forward path side extension portion 5 c and the return path side extension portion of the heat medium flow pipe 5. A shaft tube 17 through which both of 5d pass is provided, and an engaging portion 11 that engages the bridge 3 so that the shaft tube 17 can rotate with respect to the bridge 3 around the axis Sf of the shaft tube 17. . The material of the engaging portion 11 and the shaft tube 17 is not particularly limited, but a resin is preferable because it is difficult to transfer heat to the surroundings.

As shown in FIG. 6, the shaft tube 17 includes a cylindrical body 17x that is inserted so as to be fitted into the through hole 30b of the cap 30, and a flange 17y that is provided so as to protrude from the cylindrical body 17x. . The flange 17y is composed of a pair of protruding pieces provided symmetrically with respect to the axis Sf of the shaft tube 17, and a screw hole 17d into which a screw 31b (see FIG. 4) is screwed is formed. The cylindrical body 17x has a portion above the flange 17y passed through the through hole 30b of the cap 30 from below, and the flange 17y contacts the back surface of the cap 30 and is fastened to the cap 30 by a screw 31b.

When the cross section of the cylindrical body 17x is viewed, its outer shape is non-circular, and more specifically, it has a curved shape such that the short side of the rectangle swells outward. Therefore, when the cylindrical body 17x is fitted in the through hole 30b of the cap 30, the cylindrical body 17x (shaft tube 17) follows the rotation of the cap 30. That is, when the panel 4 is rotated around the axis Sf of the shaft tube 17, the cap 30 rotates together with the panel 4, and the rotation is transmitted to the shaft tube 17, so that the shaft tube 17 rotates in synchronization with the panel 4. become.

Inside the cylindrical body 17x, the forward path extending portion 5c and the return path extending portion 5d of the heat medium flow pipe 5 are passed side by side. The inner shape of the cylindrical body 17x is a shape in which the short side of the rectangle is curved in a convex arc shape toward the outer periphery, and the forward path extending portion 5c and the backward path extending portion 5d are arranged side by side. It is just the right size. More specifically, in the cylindrical body 17x, the forward path extending portion 5c and the return path extending portion 5d are arranged along the long side, and the curved surface on the short side is the forward path extending portion 5c or the return path side. It is close to the extending portion 5d so as to follow the peripheral surface.

As a result, the forward-side extension portion 5c and the return-side extension portion 5d are arranged at positions symmetrical with respect to the axis Sf of the axial tube 17 (cylindrical body 17x), and the short-side curve The surface is in contact with the peripheral surface of the forward path extending portion 5c and the backward path extending portion 5d to restrict the movement of the forward path extending portion 5c and the backward path extending portion 5d. Accordingly, the axial tube 17 can be held in a state in which the forward path extending portion 5c and the backward path extending portion 5d are restrained without imposing an excessive load on the forward path extending portion 5c and the backward path extending portion 5d. It becomes possible. The inner shape of the cylindrical body 17x is not limited to the above-described shape. If the forward-side extended portion 5c and the backward-side extended portion 5d are difficult to be displaced from each other as the panel swings, an elliptical shape is used. It may be a polygonal shape or other shapes.

As shown in FIG. 5, on the bridge 3, a ring-shaped spacer receiver 22 that is passed through the cylindrical body 17 x protruding from the through hole 3 c and is placed so as to be hooked on the bridge 3 is installed. The through-hole 3 c is substantially circular, but a groove 3 g that serves as a detent for the spacer receiver 22 is formed at a symmetrical position in the longitudinal direction of the bridge 3. The spacer receiver 22 is provided with a claw 22d that fits into the groove 3g of the through hole 3c.

The engaging portion 11 includes a spacer 23 that fits into the cylindrical body 17x that is passed through the spacer receiver 22, and a fixing member 24 that is attached to the cylindrical body 17x so as to press the spacer 23 from above. . The spacer 23 includes a cylindrical portion 23 a into which the cylindrical body 17 x is fitted, and a latching portion 23 c that protrudes from the cylindrical portion 23 a and is hooked on the spacer receiver 22. The cylindrical portion 23 a is loosely fitted to the spacer receiver 22, and the latching portion 23 c has the same circular shape as the spacer receiver 22 and abuts on the upper surface of the spacer receiver 22.

Further, the cylindrical body 17x is fitted into the through hole 23b of the spacer 23, whereby the shaft tube 17 and the spacer 23 are rotated with respect to the spacer receiver 22 as the panel 4 is rotated. Therefore, when the spacer 23 abuts on the upper surface of the spacer receiver 22, the spacer receiver 22 functions as a buffer member that reduces the frictional resistance caused by the rotation. The spacer receiver 22 is made of polyethylene terephthalate, polyacetal, or the like.

The fixing member 24 includes a cylindrical screwing portion 24x into which the cylindrical body 17x is fitted, and a pressing portion 24y that protrudes from the screwing portion 24x and contacts the upper surface of the spacer 23. The screwing portion 24x has a shape along the outer shape of the cylindrical body 17x, and specifically has a shape in which a rectangular short side is curved. A hole 24c into which the fixing screw 18 is inserted is formed in the wall 24b constituting the long side of the screwing portion 24x. Further, the presser portion 24y is formed with a notch 24d in which the connection bracket 15 is accommodated.

The fixing member 24 has the notch 24d facing down and the coupling bracket 15 is sandwiched between the fixing member 24 and the spacer 23, and the cylindrical body 17x is fitted into the screwing portion 24x, and the fixing screw 18 is cylindrically attached to the screwing portion 24x. The body 17x is fixed. As a result, the engagement portion 11 including the spacer 23 and the fixing member 24 embodies a mode of being provided on the part side protruding upward from the bridge 3 of the shaft tube 17, and further, the bridge via the spacer receiver 22. 3 will be engaged. Then, the engaging portion 11 rotates in synchronization with the shaft tube 17, and the connecting bracket 15 swings in conjunction with the rotation of the screwing portion 24x of the engaging portion 11.

As described above, in the radiation panel device 1, the plurality of panels 4 are supported by the rotation mechanisms 25 so as to be rotatable with respect to the bridge 3. Furthermore, the radiant panel device 1 includes a link mechanism 28 that connects the plurality of rotation mechanisms 25.

As shown in FIGS. 4, 5, and 7, the link mechanism 28 is provided so as to be rotatable with respect to the above-described connecting bracket 15 and the connecting bracket 15, and extends between adjacent connecting brackets 15. And a plurality of pins 13 that rotatably connect the connecting bracket 15 and the plate 12. The plate 12 is connected to each of the connection brackets 15 via pins 13.

The connecting bracket 15 has a shape obtained by flattening and extending a substantially hexagonal shape in plan view, and has a shape that tapers toward the end in the longitudinal direction. The connecting bracket 15 has through

holes

15c and 15c for engaging the pin 13 at both ends in the extending direction, and the cylindrical body 17x of the shaft tube 17 is fitted in the center in the extending direction. Through-holes 15b. The through hole 15b is configured to coincide with the outer periphery of the cylindrical body 17x in plan view.

Further, the connecting bracket 15 is fitted into a notch 24 d formed in the holding portion 24 y of the engaging portion 11, and the lower surface thereof is placed on the upper surface of the spacer 23, so that the space between the holding portion 24 y and the spacer 23 is reached. Intervene in. Furthermore, since the connecting bracket 15 is fitted with the cylindrical body 17x, the connecting bracket 15 rotates synchronously with the shaft tube 17. Therefore, the connecting bracket 15 has an axis Sf that serves as a fulcrum for swinging the panel 4. Swing around the fulcrum.

2 and 7, the plate 12 is linear, and through holes 12a through which the pins 13 are inserted are formed at predetermined intervals corresponding to the intervals between the plurality of panels 4. As shown in FIG. The plate 12 is connected to the upper part of the connection bracket 15 by pins 13. Specifically, a washer 14 is interposed between the plate 12 and the connecting bracket 15, and the pin 13 is inserted into the through hole 12 a of the plate 12, the washer 14, and the through hole 15 c of the connecting bracket 15, and the through hole It is engaged with a pin receiving portion 16 located at the lower part of 15c. In this way, the plate 12 and the connecting bracket 15 are connected to each other so as to be rotatable.

Since the radiation panel device 1 includes the link mechanism 28, when the one panel 4 is swung, the rotation mechanism 25 connected to the panel 4 rotates, and the connection bracket 15 provided in the rotation mechanism 25. Swings about the axis Sf as a fulcrum. As a result, the plate 12 connected to the connection bracket 15 moves to swing the other connection bracket 15, and all the rotation mechanisms 25 rotate in the same direction in conjunction with each other. Will swing in the same direction.

Next, the connection of the heat medium flow pipes 5 accommodated in the plurality of panels 4 and the passage of the heat medium formed by the connection of the heat medium flow pipes 5 will be described.

The forward path side extending portion 5 c and the return path side extending portion 5 d of the heat medium flow pipe 5 protrude above the bridge 3 from a symmetrical position with respect to the axis Sf of the panel 4. The forward path extending portion 5c and the backward path extending portion 5d are curved in the longitudinal direction of the bridge 3 above the bridge 3, but the forward path extending portion 5c or the backward path extending from the bridge 3 There is a sufficient margin to the curved portion of the portion 5d, in particular, the heat medium flow pipe 5 may be made of a resin and a flexible material, and even if the heat medium flow pipe 5 is twisted as the panel 4 swings, The twist can be absorbed.

On the bridge 3, the forward-side extending portion 5 c of the heat medium flow pipe 5 protruding from the panel 4 is curved to form the forward-side connecting portion 5 e, and the backward-side extending portion 5 d is curved to return the backward-side connecting portion 5 f. Is formed. Then, the return-side connecting portion 5 f that communicates with the return-path extending portion 5 d that protrudes from one panel 4 is connected to the outward-path-side connection portion 5 e that communicates with the outward-path extension portion 5 c that protrudes from the other panel 4. Yes. That is, the plurality of heat medium flow pipes 5 are connected in series by the connection between the return path side connection part 5f and the forward path side connection part 5e, and as a result, the series piping systems L1, L2, L3, and L4 are formed.

As shown in FIG. 10, the return path side connection part 5 f and the forward path side connection part 5 e are abutted against each other and connected via a joint 7 fitted in both pipes. The joint 7 is formed of a metal such as copper having corrosion resistance or a hard plastic, and has a through hole 7a through which a heat medium passes. The connection mode between the return path side connection portion 5f and the forward path side connection portion 5e is not limited to the connection via the joint 7, and can be appropriately selected depending on the material, shape, and size of the heat medium flow pipe 5.

As shown in FIGS. 8 and 9, when forming the series piping systems L1 to L4, the axis Sf is used as a reference among the forward-side extending portion 5c and the backward-side extending portion 5d protruding from the panel 4. Thus, the forward path extending portion 5c and the backward path extending portion 5d protruding from the same side are connected.

Specific description will be made with reference to FIGS. 8B and 9B. For example, the return-side extending portion 5d protruding from the third panel 4 from the left is the front side (lower left side of the drawing) from the axis Sf. The return path side extension 5d is connected to the forward path extension 5c protruding from the seventh panel 4 from the left. The forward path extension 5c is also the same as the return path extension 5d. This is the front side (lower left side of the drawing) from the axis Sf. Further, the return path extending portion 5d protruding from the seventh panel 4 from the left protrudes on the back side (upper right side of the drawing) from the axis Sf, and the return path extending portion 5d extends from the right. It is connected to the outward path extending portion 5c protruding from the first panel 4. And this outward path extension part 5c is the back | inner side (upper right side of drawing) from axis Sf similarly to the inward path extension part 5d.

In addition, in the radiation panel device 1 according to the present embodiment, a total of four (plural) series piping systems L1 to L4 are formed, and the most upstream outgoing connection part 5e of each series piping system L1 to L4 is Each of the four branch pipes 252a branched from the parallel distribution unit (also referred to as “header pipe”) 252 is connected (see FIGS. 8A and 10). Further, the most downstream return side connection portion 5f of each of the serial piping systems L1 to L4 is connected to each of the four branch pipes 253a branched from the parallel junction portion 253 (see FIGS. 9B and 10). . The parallel distribution unit 252 is connected to a heat source H that heats or cools the heat medium via a pipe 100a (see FIG. 8A), and the heat medium sent from the heat source H is connected in series. Distribute evenly to piping systems L1 to L4. The parallel junction 253 is connected to the heat source H via a pipe 100b (see FIG. 8 (a)), and aggregates the heat medium discharged from each of the series pipe systems L1 to L4. Return to H.

The parallel distribution unit 252 and the parallel merge unit 253 will be described in more detail. In addition, since the parallel distribution part 252 and the parallel merge part 253 are substantially the same structure, it demonstrates centering on the parallel distribution part 252 with reference to Fig.11 (a) and (b), and the parallel merge part 253 of FIG. Description is omitted.

The parallel distributor 252 has a cylindrical joint pipe 252g for connecting the pipe 100b connected to the heat source H, a main body pipe 252f that receives a heat medium via the joint pipe 252g, and a main body pipe 252f that branches off from the main body pipe 252f. And a plurality of branch pipes 252a that distribute the heat medium introduced to each of the serial pipe systems L1 to L4.

One end of the main body tube 252f is closed, and a joint tube 252g is provided at the other end. The joint pipe 252g is inserted into and attached to the pipe 100a, and two O-rings 252e for sealing are sandwiched between the joint pipe 253g and the pipe 100a.

The branch pipe 252a has a shape that tapers gradually toward the tip side. The branch pipe 252a is provided with a plurality of return portions 252x for preventing the branch pipe 252a from being removed. In a state where the heat medium flow pipe 5 is connected to the branch pipe 252a, an annular band 256 that is tightened from the outside is attached to the connection portion between the heat medium flow pipe 5 and the branch pipe 252a. Since the heat medium circulation pipe 5 and the branch pipe 252a are more firmly connected to each other by the band 256, it is possible to effectively prevent the branch pipe 252a from coming out of the heat medium circulation pipe 5, and further, the heat medium circulation pipe 5 It is possible to more reliably avoid water leakage from the connecting portion between the pipe and the branch pipe 252a.

The parallel distribution unit 252 has been described above, but the parallel merge unit 253 also has a substantially similar structure. Moreover, the parallel distribution part 252 and the parallel junction part 253 can use the pipe | tube comprised with various materials, such as metal pipes and resin pipes, for example.

In addition, the parallel distribution unit 252 and the parallel junction unit 253 are not fixed to the bridge 3 and are movable with respect to the bridge 3. Here, if the parallel distributor 252 and the parallel junction 253 are fixed to the bridge 3, the swing of the panel 4 is absorbed only by bending or twisting of the heat medium flow pipe 5 on the side of the series piping systems L 1 to L 4. Therefore, it is necessary to devise measures such as increasing the length of the forward path extending part 5c and the return path extending part 5d of the heat medium flow pipe 5.

On the other hand, in the radiation panel device 1 according to the present embodiment, the parallel distribution unit 252 and the parallel junction unit 253 are not directly fixed to the bridge 3 but are movable with respect to the bridge 3. Therefore, since the parallel distribution part 252 and the parallel merge part 253 move up and down, it is possible to absorb the torsion that cannot be absorbed only by the torsional absorption of the heat medium flow pipe 5. Since the movement of the heat medium flow pipe 5 accompanying the swing can be suppressed, the load applied to the heat medium flow pipe 5 can be reduced, and the panel 4 can be swung more smoothly.

Next, the operation of each member when the one panel 4 is swung will be described. As shown in FIG. 7, when one panel 4 (for example, the leftmost panel 4 in FIG. 7) is swung, the shaft tube 17 of the rotation mechanism 25 attached to the one panel 4 is connected to the bridge 3. On the other hand, it rotates around the axis Sf. Accordingly, the connection bracket 15 connected to the one panel 4 swings about the axis Sf, and the pins 13 provided at both ends of the connection bracket 15 also swing. As a result, the plate 12 moves in the left-right direction. Translate to.

As the plate 12 moves, the connection bracket 15 connected to the other panel 4 other than the one panel 4 swings in the same direction as the connection bracket 15 of the one panel 4. When the shaft tube 17 attached to is rotated in the same direction as the shaft tube 17 of the one panel 4, the other panels 4 swing in the same direction as the one panel 4. In this way, when one panel 4 is swung, all the other panels 4 are swung in the same direction in conjunction with it.

As described above, the radiation panel device 1 according to the present embodiment includes the bridge 3 that holds the plurality of panels 4 as shown in FIGS. 2 and 4, and the bridge 3 is the upper end (one end portion) of the panel 4. ) Through hole 3c at a position opposite to. The shaft tube 17 of the rotation mechanism 25 is passed through the through hole 3 c, and the rotation mechanism 25 is provided from the upper end of the panel 4 to the bridge 3 through the cap 30, and the panel 4 is connected to the bridge 3 with the shaft tube 17. Is supported so as to be rotatable around the axis Sf. The heat medium flow pipe 5 has a pair of extending

portions

5c and 5d protruding from the panel 4, and the pair of extending

portions

5c and 5d passes through the through hole 3c through the inside of the shaft tube 17 so that the shaft It protrudes from a symmetrical position with respect to the axis Sf of the tube 17.

Therefore, when the panel 4 is swung around the axis Sf of the shaft tube 17, the pair of extending

portions

5 c and 5 d are kept in the axial line Sf in a state where the mutual positional relationship is maintained in the shaft tube 17. Move around. As a result, the distance between the extending

portions

5c and 5d is prevented from changing with the swing of the panel 4, or the extending

portions

5c and 5d are prevented from being separated from the axis Sf. The positional relationship between 5c and 5d with respect to the axis Sf is maintained even if the panel 4 is swung.

Further, in the radiation panel device 1, the

connection portions

5 e and 5 f connected to the

extension portions

5 c and 5 d of the other panels 4 at the tip portions of the

extension portions

5 c and 5 d protruding from the plurality of panels 4 are provided. The connecting

portions

5e and 5f are connected to the extending

portions

5c and 5d protruding from the same side of the connecting

portion

5e and 5f of the extending

portions

5c and 5d protruding from the other panel 4 with respect to the axis Sf. The

parts

5e and 5f are connected. That is, as shown in FIG. 8 and FIG. 9, the extending

portions

5 c and 5 d protruding from the same side are connected to each rotation mechanism 25 that rotatably supports each panel 4, thereby connecting the panels 4. Thus, a plurality of serial piping systems L1 to L4 of the heat medium flow pipe 5 are formed. Accordingly, the interval between the extending

portions

5c and 5d connected to each other coincides with the interval between the axis lines Sf of the axial tubes 17 through which both the extending

portions

5c and 5d pass, and this interval is maintained. The panel 4 will swing. As a result, it is possible to prevent the interval between the

extended portions

5c and 5d connected to each other from being widened or narrowed by the swinging of the panel 4, so that the rotation failure of the panel 4 can be prevented and the panel 4 can be swung smoothly. Can be made.

Furthermore, since the pair of extending

portions

5c and 5d of the heat medium circulation pipe 5 passes through the inside of the shaft pipe 17, the movement of the heat medium circulation pipe 5 accompanying the swing of the panel 4 can be suppressed. 4 can reduce the load on the heat medium flow pipe 5 at the time of swinging, and the heat medium flow pipe 5 can be kept warm in the shaft pipe 17.

In addition, the rotation mechanism 25 holds the extending

portions

5c and 5d in the axial tube 17 in a state in which movement of the extending

portions

5c and 5d in the direction approaching and separating from the axis Sf is constrained. 17 is constrained in a state of being symmetric with respect to the axis line Sf, even if the panel 4 is swung, the positional deviation between the extending

portions

5c and 5d is unlikely to occur in the shaft tube 17. As a result, the smooth swinging state of the panel 4 can be stably maintained. The direction in which the extending

portions

5c and 5d approach and separate from the axis Sf is intended to mean the direction in which the extending

portions

5c and 5d approach the axis Sf and the direction in which the extending

portions

5c and 5d separate from the axis Sf.

Further, the shaft tube 17 is fixed to the upper end of the panel 4 through the cap 30 and, as shown in FIG. 5, is loosely fitted in the through hole 3c so as to protrude from the bridge 3, and is rotated by the rotation mechanism. 25 is provided at a portion protruding from the bridge 3 of the shaft tube 17 and has an engaging portion 11 that protrudes from the shaft tube 17 and engages with the bridge 3. The shaft tube 17 is fixed to the end portion and rotates relative to the bridge 3 together with the panel 4. As a result, the

extension portions

5 c and 5 d of the heat medium flow pipe 5 constrained in the shaft tube 17 are also swung with the swing of the panel 4, and the heat medium flow pipe 5 is swung with the swing of the panel 4. This is effective in reducing the twisting of the panel 4 and making the panel 4 swing more smoothly.

Further, since the inner periphery of the shaft tube 17 has a non-circular cross-sectional shape in a direction orthogonal to the axis Sf, the rotational position relative to the bridge 3 when the shaft tube 17 is attached is determined, and the bridge 3 of the panel 4 is determined. Can be easily positioned.

Moreover, since the radiation panel apparatus 1 is provided with the link mechanism 28 which connects the some rotation mechanism 25 as FIG. 7 shows, the some rotation mechanism 25 which supports each of the some panel 4 rotatably is a link mechanism. 28 are connected. For this reason, when one panel 4 is swung, the other panel 4 is swung by the same amount as the one panel 4 with the rotation of the rotation mechanism 25 and the swing of the link mechanism 28. As a result, the interval between the extending

portions

5c and 5d is more strictly maintained, and rotation failure can be further suppressed.

The link mechanism 28 is connected to the plurality of rotation mechanisms 25, and is connected to the plurality of connection brackets 15 that swing together with the shaft tube 17 around the axis Sf. Since the plate 12 extending over the connection bracket 15 is provided, the angles of the panels 4 with respect to the extending direction of the plate 12 can be the same. Therefore, each panel 4 can be swung more accurately in the same direction.

Further, the radiant panel device 1 includes series piping systems L1 to L4 formed by connecting a plurality of heat medium flow pipes 5 at the

connection portions

5e and 5f, and includes the heat source H and the series piping systems L1 to L4. And a parallel distribution unit 252 that distributes the heat medium to each of the serial piping systems L1 to L4, and a heat medium discharged from each of the serial piping systems L1 to L4 between the heat source H and the serial piping systems L1 to L4 The parallel distribution unit 252 and the parallel merge unit 253 can swing up and down as the panel 4 rotates, for example, as indicated by an arrow Y in FIGS. 8 and 9. .

Each of the serial piping systems L1 to L4 may be slightly twisted around the axis of the heat medium flow pipe 5 as indicated by an arrow X in FIGS. 8 and 9 as the panel 4 swings. Then, since the parallel distribution part 252 and the parallel merging part 253 are bent and the heat medium flow pipe 5 is allowed to be twisted, the panel 4 is formed by applying a resistance force to the twist of the heat medium flow pipe 5. The occurrence of rotation failure can be suppressed.
