  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings, the same or corresponding members are denoted by the same or similar reference numerals, and the redundant description will be omitted.

  First, a radiation panel 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a partial front view of the radiation panel 1. FIG. 2 is a partial perspective view of the radiation panel 1. The radiation panel 1 includes a heat radiation pipe 10 as a heat medium pipe, a panel member 20, a fixing member 30, and a spacer 40. The radiation panel 1 is installed in the heating and cooling room R as a space for heating and cooling. The heating and cooling room R is a room to be cooled or heated. In the following description, the radiation panel 1 is installed on the ceiling of the heating and cooling room R.

  The heat radiation pipe 10 is a member for transmitting the cold heat (during cooling) or the heat (during heating) held by the heat medium M to the panel member 20 by flowing the heat medium M inside. The heat dissipating pipe 10 is preferably made of a material that is excellent in heat conductivity and hard to deform, and preferably has a shape that does not deform even when pressed by the fixing member 30. In the present embodiment, a copper pipe having a circular cross section is used as the heat dissipation pipe 10. The heat radiation pipe 10 is typically a straight pipe.

  The panel member 20 is a member that radiates cold or heat received from the heat medium M through the heat radiation pipe 10 to the cooling and heating chamber R. Here, the heat reception is the transfer of cold heat or heat by heat transfer from the heat medium M flowing through the heat radiation pipe 10 to the panel material 20. Strictly speaking, the heat is transferred from the panel material 20 having a temperature higher than that of the heat medium M to the heat medium M instead of the heat transfer from the heat medium M to the panel material 20. In the present specification, for the sake of convenience, cold heat is also expressed as "receive heat". In addition, cold heat is not radiated from the panel material 20, but for example, heat radiated from a human being or the like is not absorbed and reflected by the panel material 20 having a low temperature, thereby producing a cool feeling. For the sake of convenience, cold heat will be expressed as "radiate" for the sake of illustration. Cold heat and heat are heat for making the temperature of the panel material 20 different from the ambient environment temperature, and in this sense it is simply referred to as "heat" when the direction of the temperature (whether it is raised or lowered) is not distinguished. In some cases. For example, “heat reception” is a general term for heat transfer of cold heat or heat from the heat medium M to the panel material 20. The panel material 20 is formed to be elongated as shown in FIG. In the present embodiment, the panel member 20 has a length of about 85 mm in the width direction W and a length of about 15 to 20 mm in the height direction H. The length of the panel material 20 in the longitudinal direction L is determined by appropriately cutting the one having a length of 4000 mm in accordance with the size of the heating and cooling chamber R. In the present embodiment, the panel member 20 is made of a material in which the surface of a core of a plate-like aluminum alloy is coated.

  Here, referring to FIG. 3A together, the configuration of the panel material 20 will be described. FIG. 3A shows a cross section orthogonal to the longitudinal direction L, and this cross section may be called an axial orthogonal cross section. Hereinafter, in the description of the configuration of the panel material 20 in this paragraph, unless otherwise noted, it is assumed to be in an axis orthogonal cross section. The panel member 20 has a shape in which an angular C-shape is turned to the side, and has a main heat radiating portion 21, an erecting portion 23 and a small protrusion 25. The main heat radiating portion 21 is a portion facing the air conditioning and heating room R when the radiation panel 1 is installed in the air conditioning and heating room R. The main heat radiating portion 21 is formed in a linear shape extending in the width direction W. The main heat radiating portion 21 is a portion that radiates heat toward the heating and cooling chamber R. The standing portions 23 are respectively connected to both ends of the main heat radiating portion 21 and extend in the height direction H. The pair of upright portions 23 both extend to the opposite side to the heating and cooling room R in a state where the radiation panel 1 is installed in the heating and cooling room R. In the present embodiment, the pair of upright portions 23 extend at a right angle to the main heat radiating portion 21. The small projection 25 is connected to each of the pair of upright portions 23. Each of the small protrusions 25 is connected to an end of the both ends of the standing portion 23 on the opposite side to the end to which the main heat radiating portion 21 is connected. The pair of small protrusions 25 extend in the width direction W so as to approach each other. In the present embodiment, the pair of small protrusions 25 extend at a right angle with respect to the standing portion 23. In the panel member 20, a fitting space 29 is formed in a portion surrounded on three sides by the small projection 25, the standing portion 23, and the main heat radiating portion 21. The fitting space 29 is a space in which the fixing member 30 is fitted, and is formed at both ends in the width direction W of the panel member 20. The length of the small projection 25 in the width direction W may be determined in consideration of the manner of fitting of the fixing member 30, and may be, for example, 5 mm to 15 mm, and is 10 mm in the present embodiment. The fitting space 29 is continuously formed in the longitudinal direction L. In addition, although the main heat radiating part 21, the standing part 23, and the small protrusion 25 are distinguished for convenience of explanation, and are typically integrally formed and comprise the panel material 20, several members are The panel material 20 may be configured by welding or the like.

  The fixing member 30 is a member for fixing the heat radiation pipe 10 to the panel member 20. The fixing member 30 is configured by forming a notch to which the heat radiation pipe 10 and the panel member 20 can be fitted to a plate-like member. Although the fixing member 30 is mainly shown in FIGS. 1 and 2 as to the length in the width direction W to which one set of one set of one heat release pipe 10 and one panel material 20 can be fixed. Has a length in the width direction W in which a plurality of sets of the heat radiation pipe 10 and the panel member 20 can be fixed. The length in the height direction H of the fixing member 30 is typically about 2 to 5 times the outer diameter of the heat radiation pipe 10, and in the present embodiment, 3.5 times the outer diameter of the heat radiation pipe 10 It has become. In the present embodiment, the fixing member 30 is configured by processing a plate-like aluminum alloy.

  Here, the configuration of the fixing member 30 will be described with reference to FIG. 3 (B). FIG. 3B shows an axially orthogonal cross section. Hereinafter, in the description of the configuration of the fixing member 30 related to this paragraph, unless otherwise specified, it is assumed to be in an orthogonal cross section. The fixing member 30 is configured by forming a through notch 34 through which the heat radiation pipe 10 penetrates and a fitting notch 32 into which the panel member 20 fits, in a strip-like flat plate member. Both the through notch 34 and the fitting notch 32 are formed by cutting the lower side 30 bs side. The lower side 30 bs is a side which becomes the panel material 20 side when the fixing member 30 is incorporated as the radiation panel 1.

  The fitting notch 32 is formed by connecting a lower notch 32n and a center notch 32f having different lengths in the width direction W. The lower notch 32 n is a rectangular (rectangular or square) notch in contact with the lower side 30 bs. The middle notch 32f is continuous with the lower notch 32n on the opposite side to the lower side 30bs. The lower notch 32 n has a length in the width direction W shorter than that of the middle notch 32 f. Further, an imaginary line bisecting the lower notch 32n in the width direction W and an imaginary line bisecting the center notch 32f in the width direction W are arranged in the same straight line. The fitting notch 32 formed in this manner is generally T-shaped. In the fixing member 30, a fitting portion 31 is formed by the fitting notch 32 between the end in the width direction W of the middle notch 32f and the lower side 30bs, and the fitting portion 31 protrudes toward the lower notch 32n. The fitting portion 31 is a portion to be fitted into the fitting space 29 of the panel material 20. The fitting portion height 31H, which is the length in the height direction H of the fitting portion 31, is the same as or slightly shorter than the length in the height direction H of the fitting space 29. When the fitting portion 31 is fitted in the fitting space 29, the fixing member 30 is perpendicular to the main heat radiating portion 21 and the gap between the panel member 20 and the fixing member 30 is as small as possible. It is a length. The fitting portion width 31W, which is the length in the width direction W of the fitting portion 31, is the same as or slightly longer than the length in the width direction W of the fitting space 29, and is formed to about 10 mm to 12 mm in this embodiment. It is done. A unit width 30bW, which is the length in the width direction W between the fitting notches 32 adjacent to each other across the through notch 34, is equal to or slightly shorter than the length between the inner walls of the pair of upright portions 23 of the panel material 20. . The unit width 30 bW is the length in the width direction W between the boundary between the closest fitting portion 31 and the lower notch 32 n with the through notch 34 interposed therebetween. The lower notch width 32 nW, which is the length of the lower notch 32 n in the width direction W, may be appropriately determined in consideration of the gap between the adjacent panel members 20 when a plurality of panel members 20 are fitted in the fixing member 30. In the present embodiment, as shown in FIG. 1, the fitting notch 32 is a groove in which the support member B connected to the housing S can be fitted. That is, the fitting notch 32 doubles as a support fitting groove. Therefore, the length in the height direction H of the center notch 32f may be appropriately determined in consideration of the space in which the support member B is fitted. Note that an end side 30es, which is an end of the fixing member 30 in which the plurality of panel members 20 are fitted, in the width direction W is the end of the panel member 20 disposed at the end of the end where there is no adjacent panel member 20. It is cut along the straight line which extended the edge of the center notch 32f which extends from the fitting part 31 fitted in the fitting space 29 at right angles to the lower side 30bs.

  The through notch 34 is formed in contact with the lower side 30 bs. The through cutout 34 is the side of the virtual extension 30 bsv from the opposing side 34 ts that is the side opposite to the virtual extension 30 bsv of the lower side 30 bs with respect to the rectangular basic shape (the main heat radiation portion 21 side when it becomes the radiation panel 1 Is formed in a deformed shape so as to form a pressing projection 33 protruding in the direction. The through notch 34 is typically formed at a position that bisects the unit width 30 bW. The length in the width direction W of the through notch 34 is the same as or slightly larger than the outer diameter of the heat dissipation pipe 10, and the length in the width direction W of the spacer 40 when the spacer 40 is attached to the heat dissipation pipe 10 is outside the heat dissipation pipe 10 If it is larger than the diameter, it is equal to or slightly larger than the length in the width direction W of the spacer 40. The distance from the virtual extension line 30 bsv to the opposing side 34 ts is larger than the outer diameter of the heat dissipation pipe 10, preferably 1.3 times to 1.6 times the outer diameter of the heat dissipation pipe 10. The outer diameter of the pipe 10 is about 1.4 times to 1.5 times. The depression depth 34dH, which is the distance from the virtual extension 30bsv to the tip of the pressing projection 33, is smaller than the outer diameter of the heat dissipation pipe 10, preferably 0.7 to 0.9 times the outer diameter of the heat dissipation pipe 10. In the present embodiment, the outer diameter of the heat radiation pipe 10 is about 0.8 times to 0.85 times.

  The spacer 40 is a member disposed between the heat radiation pipe 10 and the panel member 20 as shown in FIGS. 1 and 2. The spacer 40 is formed to be elongated in the longitudinal direction L in the same manner as the heat dissipating pipe 10. In the spacer 40, the surface in contact with the main heat radiation portion 21 of the panel member 20 is formed flat, and the surface in contact with the heat release pipe 10 which is the surface on the back side of the plane is curved along the surface of the heat release pipe 10. It is formed. The spacer 40 is formed to be in surface contact with both the heat radiation pipe 10 and the main heat radiation portion 21. By being formed in this manner, the spacer 40 contributes to indirectly increasing the heat transfer area between the heat radiation pipe 10 and the panel material 20. The spacer 40 is preferably formed of a material excellent in heat conduction, and in the present embodiment, is formed of an aluminum alloy. The spacer 40 is formed so that the length in the width direction W is equal to or less than the length in the width direction W of the through cutout 34 of the fixing member 30.

  As described above, in the radiation panel 1 in which each member is configured, the tip end of the pressing projection 33 is bent along the longitudinal direction L of the outer surface of the heat radiation pipe 10 and is in contact with the heat radiation pipe 10. The radiation panel 1 is configured such that the bent portion of the tip of the pressing projection 33 presses the heat radiation pipe 10 toward the main heat radiation portion 21. With such a configuration, in the radiation panel 1, the heat radiation pipe 10, the spacer 40, and the main heat radiation portion 21 are in close contact with each other.

  Continuing to refer to FIG. 4, a method of manufacturing the radiation panel 1 according to the embodiment of the present invention will be described. FIG. 4 is a side sectional view showing the manufacturing procedure of the radiation panel 1. In the following description of the method of manufacturing the radiation panel 1, when referring to the detailed configuration of the radiation panel 1, FIGS. 1 to 3 will be appropriately referred to. In order to manufacture the radiation panel 1, first, as shown in FIG. 4A, the heat radiation pipe 10 to which the spacer 40 is attached is placed on the surface of the main heat radiation portion 21 of the panel material 20 (heat medium pipe Mounting process). At this time, the heat radiation pipe 10 is placed so as to extend in the longitudinal direction L at the center in the width direction W of the surface in the direction in which the standing portion 23 of the main heat radiating portion 21 extends. The same number of panel members 20 on which the heat radiation pipe 10 to which the spacer 40 is attached is placed is prepared as the through-cuts 34 formed in the fixing member 30.

  Next, as shown to FIG. 4 (B), the fixing member 30 is attached to the panel material 20 in which the thermal radiation pipe 10 was mounted (fixed member attachment process). The fixing member 30 inserts the pair of fitting portions 31 into the pair of fitting spaces 29 of the panel member 20 while passing the heat release pipe 10 through the through notch 34 at one end of the panel member 20 in the longitudinal direction L, and then installed It is attached to the panel material 20 so as to be moved in the longitudinal direction L to the position. At this time, in the fixing member 30, as shown in FIG. 3B, the pressing projection 33 is not bent, and the entire pressing projection 33 exists on the same plane as the plate-like portion around the through notch 34. It has become. Therefore, the surface of the fixing member 30 is inclined not perpendicular to the surface of the main heat radiating portion 21 and is curved so that the portion of the pressing projection 33 is convex. In the attachment of the fixing member 30 to the panel member 20, one fixing member 30 in which a plurality of through notches 34 are formed may be simultaneously attached to the plurality of arranged panel members 20, and the plurality of through notches 34 The panel members 20 may be fitted one by one to each through notch 34 of one formed fixing member 30.

  When the fixing member 30 is attached to the panel member 20 in an oblique state with respect to the surface of the main heat radiating portion 21, the surface of the fixing member 30 faces the surface of the main heat radiating portion 21 as shown in FIG. The fixing member 30 is raised so as to be at a right angle (fixed member raising step). To raise the fixing member 30 is to stand the fixing member 30 that is oblique to the main heat radiating portion 21. Here, when raising the fixing member 30 which is inclined, the upper end of the fitting portion 31 is a small protrusion of the panel material 20 before the fixing member 30 becomes perpendicular to the surface of the main heat radiating portion 21. As a result, the pressing projection 33 hits the heat radiation pipe 10. When the fixing member 30 is raised by applying a further large force from this state, the tip of the pressing projection 33 in contact with the heat radiation pipe 10 is bent so as to protrude from the plate-like portion around the through cutout 34. Then, when the fixing member 30 is perpendicular to the surface of the main heat radiating portion 21, the tip of the pressing projection 33 which is bent to protrude is in a state of pressing the heat radiating pipe 10 toward the main heat radiating portion 21. In the radiation panel 1 manufactured in this manner, the heat radiation pipe 10 is in close contact with the main heat radiation portion 21 via the spacer 40, and the amount of heat transferred from the heat medium M in the heat radiation pipe 10 to the main heat radiation portion 21 is reduced. Can be suppressed.

  In the radiation panel 1 manufactured as described above, the support members B are attached to appropriate positions of the plurality of center notches 32f, and the support members B are connected to the casing S of the ceiling. It will be installed on the ceiling. Thus, the radiation panel 1 can be simply installed in the air conditioning room R as a unit. In the radiation panel 1 installed on the ceiling of the heating and cooling room R, one end of a plurality of heat radiation pipes 10 is connected by a forward header (not shown), and the opposite side to the end where the forward header (not shown) is connected The other ends are connected by a return header (not shown). The forward header (not shown) is connected to the heat source machine (not shown) via the cold and hot water delivery pipe (not shown) and the return header (not shown) via the cold and hot water return pipe (not shown) There is. A heat source machine (not shown) is an apparatus for adjusting the temperature of the heat medium M. Thus, the radiation panel 1 cooperates with the return header (not shown), the cold / hot water return pipe (not shown), the heat source machine (not shown), the cold / hot water delivery pipe (not shown), the forward header (not shown) And make up an air conditioning system.

  With continuing reference to FIGS. 1 to 3, the operation of the radiation panel 1 will be described. Here, an example of the operation at the time of cooling will be described. In addition, the specific temperature mentioned below is an illustration for the ease of understanding, and is not limited to the temperature. When cooling of the air conditioning room R is started, the heat source machine (not shown) is activated, and the heat medium M comes out of the heat source machine (not shown), and the hot and cold water delivery pipe (not shown) It circulates to radiation panel 1, a return header (not shown), a cold and warm water return pipe (not shown), and a heat source machine (not shown). The circulating heat medium M is cooled to about 17 ° C. in a heat source machine (not shown). When the heat medium M having a temperature of about 17 ° C. flowing into the radiation panel 1 flows through the heat radiation pipe 10 toward the return header (not shown), the heat radiation portion 10 of the panel member 20 cools the heat via the heat radiation pipe 10 and the spacer 40. To communicate. At this time, since the spacer 40 is in surface contact with the heat radiation pipe 10 and the main heat radiation portion 21, the heat transfer area can be increased compared to the case where the spacer 40 is not provided, and the cooling heat of the heat medium M can be efficiently obtained. It can be transmitted to the main heat radiating portion 21. Further, since the heat radiation pipe 10 is pressed to the main heat radiation portion 21 side by the bent tip portion of the pressing projection 33 of the fixing member 30, the heat radiation pipe 10 closely contacts the main heat radiation portion 21 via the spacer 40 A reduction in the amount of heat transferred from the medium M to the main heat radiating portion 21 can be suppressed. The transfer of cold heat from the heat medium M to the main heat radiating portion 21 is heat exchange between the heat medium M and the main heat radiating portion 21 through the heat radiation pipe 10 and the spacer 40, whereby the main heat radiating portion 21 is cooled The temperature of the medium M rises.

  The radiation panel 1 which receives cold heat from the heat medium M and lowers the temperature of the main heat radiating portion 21 radiates cold heat toward the heating and cooling room R, and cools the heating and cooling room R. Since the radiation of cold heat from the radiation panel 1 is performed from the entire ceiling surface of the air conditioning and heating room R, temperature unevenness does not easily occur in the air conditioning and heating room R. On the other hand, the temperature of the heat medium M heat-exchanged with the main heat radiating portion 21 is approximately 19 ° C. The heat medium M raised to about 19 ° C. exits the radiation panel 1 and flows into the heat source machine (not shown) through the return header (not shown) and the warm water return pipe (not shown). The heat medium M at about 19 ° C. flowing into the heat source machine (not shown) is cooled to about 17 ° C. and taken out of the heat source machine (not shown), and thereafter the above-mentioned operation is repeated.

  During heating, the heat medium M is heated to about 36 ° C. in a heat source machine (not shown). The heat medium M having a temperature of about 36 ° C. flowing into the radiation panel 1 exchanges heat with the main heat radiation portion 21 and drops to about 34 ° C. The radiation panel 1 which receives heat from the heat medium M at about 36 ° C. and the temperature of the main heat radiating part 21 rises, radiates heat toward the heating and cooling room R, and heats the heating and cooling room R. The heat medium M which exchanges heat with the main heat radiating portion 21 and is lowered to about 34 ° C. is led to a heat source machine (not shown), heated to about 36 ° C. and taken out from the heat source machine (not shown) , Repeat the above action.

  As described above, according to the radiation panel 1 according to the present embodiment, the heat radiation pipe 10 is pressed to the main heat radiation portion 21 side by the bent tip portion of the pressing projection 33 of the fixing member 30, so heat radiation The pipe 10 is in close contact with the main heat radiating portion 21 via the spacer 40, and a reduction in the amount of heat transfer from the heat medium M to the main heat radiating portion 21 can be suppressed. Moreover, since the spacer 40 is provided, the heat transfer area from the heat radiation pipe 10 to the main heat radiation part 21 can be increased, and the cold heat of the heat medium M can be efficiently transmitted to the main heat radiation part 21.

  In the above description, the radiation panel 1 is installed on the ceiling of the heating and cooling room R. However, the radiation panel 1 may be installed on the wall of the heating and cooling room R together with or instead of the ceiling.

  In the above description, a copper pipe having a circular cross section is used as the heat dissipation pipe 10. However, from the viewpoint of increasing the amount of heat transfer when the spacer 40 is not used, the cross section of the heat dissipation pipe 10 may be flat or square. Good. Moreover, although the material of the heat radiation pipe 10 may be something other than a copper pipe, such as aluminum, an iron pipe, etc., it is preferable that it is a thing with comparatively high heat conductivity.

  In the above description, the main heat radiating portion 21 is formed in a linear shape extending in the width direction W, but may be curved.

  In the above description, although the panel material 20 uses the aluminum alloy as the core material, a material other than the aluminum alloy may be used as the core material. However, in view of thermal conductivity and weight reduction, it is preferable to use an aluminum alloy as the core material.

  In the above description, the spacer 40 is formed separately from the panel member 20. However, the spacer 40 may be integrally formed with the panel member 20. In this case, when the main heat radiating portion 21 of the panel material 20 is pressed to form the spacer 40, a line of depressions after being pressed is formed on the surface of the main heat radiating portion 21 opposite to the spacer 40. It may be The line of depressions formed in this way can be a design accent. The spacer 40 may be omitted, and the heat radiation pipe 10 may be positioned with respect to the panel member 20 by the fixing member 30.

In the above description, the panel material 20 in the axis orthogonal cross section has a shape in which the angular C-shape is turned to the side, but the standing portion 23 and the small protrusion 25 have a rounded shape. It may be. In this case, the fitting portion 31 of the fixing member 30 also has a rounded shape.
FIG. 5 shows an exploded partial front view of a radiation panel 1A according to a modification. In the radiation panel 1A, the standing portion 23A and the small projection 25A of the panel material 20A are rounded. In the panel member 20A, the linear portion is the main heat dissipation portion 21, and the portion from the portion where the tangent of the outer surface of the panel member 20A makes an angle with the main heat dissipation portion 21 It becomes the standing part 23A, and the portion curved inward beyond the standing part 23A becomes the small protrusion 25A. In the panel member 20A, the erected portion 23A and the small projection 25A are continuous with the same curvature. In the panel member 20, the fitting space 29A has an arc shape. On the other hand, in the fixing member 30A, the fitting portion 31A is formed in a quarter arc shape along the contour inside the standing portion 23A of the panel material 20A. Thus, the side intersecting the lower side 30 bs of the lower notch 32 nA is formed in an arc shape diverging from the center notch 32 fA side to the lower side 30 bs side. In the center notch 32fA, sides on both ends in the width direction W are formed in a semicircular shape. The configuration of the through notch 34 of the fixing member 30A is the same as that of the fixing member 30 (see FIGS. 1 and 3B). Further, the heat radiation pipe 10 and the spacer 40 are the same as those of the radiation panel 1 (see FIGS. 1 and 2). The radiation panel 1A configured as described above can be manufactured in the same procedure as the radiation panel 1 (see FIGS. 1 and 2). In addition, since the panel member 20A and the fixing member 30A in which the through cutout 34 is not formed have the same shape as those circulating as the outer wall material of the building, the circulating member is procured and fixed There is an advantage that the radiation panel 1A can be easily manufactured by forming the through notch 34 in 30A and separately procuring the heat radiation pipe 10 and the spacer 40 if necessary.
