Description

  The present invention relates to radiant panels. More specifically, the present invention relates to a radiation panel used for radiant cooling and heating air conditioning, which has an excellent cooling and heating effect and is capable of sufficiently treating the generated dew condensation.

  Radiant cooling and heating air conditioning is used as air conditioning equipment for the room and the like. This radiant cooling and heating air conditioning cools and heats the air by radiant heat exchange, so compared to convection air conditioning in which cold air or warm air is forcedly circulated by a fan, the indoor set temperature can be relaxed and energy can be saved, resulting in uneven temperature distribution and dust. It has the advantage that it is difficult and that the blowing noise can be suppressed.

  In this radiant cooling / heating air conditioning, cold / hot water serving as a heat medium is circulated in a pipe path provided inside the radiant panel to cool or heat the radiant panel. Then, radiant heat is directly exchanged between the radiant panel and the human body to cool and heat the indoor space. Further, in the radiation panel, the air is cooled and heated by convective heat radiation through the air.

  There are two types of radiant panels for radiant cooling / heating, which are installed on the ceiling or wall of a room, or vertically installed on the floor.

  For example, as a radiation panel of a type installed on a ceiling surface, a ceiling radiation type air conditioning system described in Patent Document 1 has been proposed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention.
The structure shown below is an example of the radiation panel to which the present invention is applied, and the content of the present invention is not limited to this, and the setting can be changed appropriately.

  As shown in FIG. 1A, a radiant panel A, which is an example of a radiant panel to which the present invention is applied, is a radiant panel of a vertical type radiant cooling and heating air conditioner that is erected on a floor surface of an indoor space.

  In the following description, based on FIG. 1A, the upper and lower sides in the figure will be referred to as “upper or upper side”, “lower or lower side” and “vertical direction or vertical direction”. Further, based on FIG. 1A, the left and right in the figure are referred to as “left or left side”, “right or right side” and “left and right direction or horizontal direction”. Further, with reference to FIG. 1A, they are referred to as “outer or outer” and “inner or inner” along the left-right direction in the figure.

  Further, with reference to FIG. 1B, the left side of the drawing is referred to as “front or front side”, and the right side of the drawing is referred to as “back or back side”. Further, with reference to FIG. 1B, the left-right direction (front-back direction) in the figure is referred to as “thickness direction”. Further, with reference to FIG. 1B, the inside along the left-right direction in the figure is referred to as the “center side in the thickness direction” and the outside is referred to as the “outside in the thickness direction”.

  As shown in FIG. 1A, the radiation panel A includes a heat dissipation portion 1, a pillar member 2a, a pillar member 2b, an upper louver 3 and a lower louver 4.

  The heat radiating unit 1 is a member in which a pipe 10 (see FIG. 2) that circulates tap water serving as a cooling / heating medium is covered with a panel unit 11 (see FIG. 1A), and is a member that generates radiative heat radiation and convective heat radiation. ..

  The pillar member 2a and the pillar member 2b are support members for standing the radiation panel A on the floor surface, and are frame members for ensuring the overall strength of the radiation panel A. Although the pillar member 2a and the pillar member 2b are members that form the radiation panel A, the pillar member and the wall surface that are already provided in the space in which the radiation panel is installed are referred to as the pillar member 2a and the pillar member 2b. It can also be used as an alternative structure.

  The upper louver 3 and the lower louver 4 are members that cover the pipe 10 at the upper and lower positions of the heat dissipation unit 1 to make it difficult to visually recognize the pipe 10 from the outside. Further, in the region of the heat dissipation portion 1, the pipe 10 is covered with the panel portion 11, so that the panel portion 11 is visually recognized in appearance.

  As shown in FIGS. 2A and 2B, the pipe 10 has a medium supply unit 100, a main pipe 101, a connection pipe 102, and a medium discharge unit 103.

  The pipe 10 is configured to supply tap water from the medium supply unit 100 to the pipe path formed by the main pipe 101 and the connection pipe 102 and discharge the tap water via the medium discharge unit 103. That is, the pipe 10 forms a serial fluid path as a flow path of tap water serving as a cooling / heating medium.

  In addition, the medium discharge unit 103 and the medium supply unit 100 are connected by a circulation path constituted by a pipe (not shown), and a predetermined medium temperature adjusting mechanism for heating or cooling tap water is provided in the middle of this circulation path. Has been.

  That is, a control mechanism (not shown) outputs a control signal to adjust the temperature of the indoor space in which the radiation panel A is installed, and the medium temperature adjusting mechanism adds tap water flowing through the circulation path in response to the control signal. Warm or cool. The tap water of which the temperature is adjusted is supplied to the pipe path formed by the main pipe 101 and the connecting pipe 102.

  The main pipe 101 is a tubular body having a predetermined length, and a plurality of main pipes 101 are arranged at regular intervals. Further, the plurality of main pipes 101 are connected to each other by connecting pipes 102 having a substantially U-shape at the upper end portion or the lower end portion of the adjacent main pipes 101.

  The main pipe 101 and the connecting pipe 102 are made of stainless steel. The main pipe 101 is formed by extrusion molding.

  Here, it is not always necessary that the cold / hot medium that circulates in the pipe path is tap water, and a temperature-adjustable liquid that can be circulated can be used as the fluid. However, when the size of the radiation panel and the number of installations are large, if tap water can be used as the cooling / heating medium, the running cost of the radiation panel can be suppressed as compared with the case where the antifreezing liquid is used as the medium.

  Further, the main pipe 101 and the connecting pipe 102 do not necessarily have to be formed of stainless steel, and a material capable of circulating a cooling / heating medium inside and capable of conducting heat to a panel portion described later is used. However, other metals can also be used. However, it is preferable that the main pipe 101 and the connection pipe 102 are made of stainless steel because the pipe path is less likely to be corroded by the cooling / heating medium.

  Further, as the shape of the main pipe 101, it is not always necessary to adopt a round tubular body having a substantially cylindrical outer shape. For example, as the shape of the main pipe 101, it is also possible to adopt a tubular body having a prismatic outer shape. When a cylindrical body with a prismatic outer shape is used for the main piping, the cooling and heating medium flowing inside the main piping is more likely to be inside the through hole than the outer circumference of the main piping, as compared to the main piping with a substantially cylindrical outer shape. It may easily flow to a region close to the surface (a region outside the center of the through hole, not the center of the through hole), and the heat exchange rate by the cooling / heating medium can be improved.

  Further, as shown in FIG. 2B, it is not always necessary to adopt a structure in which the medium supply unit 100 and the medium discharge unit 103 are provided above the radiation panel. For example, it is possible to adopt a structure in which the medium supply unit and the medium discharge unit are provided at the bottom of the radiation panel.

  Further, the radiation panel does not necessarily have to have a structure having a series of fluid paths. For example, as shown in FIGS. 9 (a) and 9 (b), a radiation panel having parallel fluid paths can be used. 9A shows a structure in which the medium supply unit 100 and the medium discharge unit 103 are provided in the upper portion, and FIG. 9B shows the structure in which the medium supply unit 100 and the medium discharge unit 103 are provided in the lower portion. It is a structure.

  As described above, in the radiation panel having the parallel fluid paths, the plurality of main pipes are composed of the plurality of supply-side main pipes 101a and the plurality of discharge-side main pipes 101b.

  Further, the ends of the plurality of supply-side main pipes 101a on the medium supply unit 100 side are connected by a connection pipe 102a. Further, the ends of the plurality of discharge-side main pipes 101b on the medium discharge portion 103 side are connected by a connection pipe 102c. Further, the ends of the plurality of supply-side main pipes 101a opposite to the medium supply unit 100 and the ends of the plurality of discharge-side main pipes 101b opposite to the medium discharge unit 103 are connected by a connection pipe 102b. ing.

  Further, in the fluid path shown in FIG. 9A, the number of main pipes 101b on the discharge side is larger than the number of main pipes 101a on the supply side. Further, in the fluid path shown in FIG. 9B, the number of main pipes 101a on the supply side is larger than the number of main pipes 101b on the discharge side. In the case of a structure having parallel fluid paths, by adjusting the number of main pipes on the supply side and the discharge side depending on whether the medium supply unit 100 and the medium discharge unit 103 are provided above or below, It is possible to have a structure in which the air generated in the piping path of the piping can be easily discharged to the discharge portion side.

  As described above, the radiation panel to which the present invention is applied can be applied not only to the fluid paths in series but also to the structure having fluid paths in parallel.

  Further, the end of the main pipe 101 and the end of the connecting pipe 102 are connected by a mechanical joint. FIG. 6 (b) shows an example of a method of connecting end portions by a mechanical joint used in the present invention.

  As shown in FIG. 6 (b), the end 101 a of the main pipe 101 and the end 102 a of the connecting pipe 102 are respectively inserted inside the tubular joint body 104 made of stainless steel, and the dedicated machine tool X is used. Then, pressure is applied from outside the joint body 104 to plastically deform (compress) the joint body 104. Then, the end portion 101a of the main pipe 101 and the end portion 102a of the connecting pipe 102 are connected to each other via the joint body that is plastically deformed.

  In this way, by the structure in which the joint body 104 is plastically deformed and crimped to be connected, it is possible to connect the main pipe 101 and the connecting pipe 102 without using a connecting tool such as a nipple or packing. .. As a result, the risk of water leakage of the cooling / heating medium due to damage to the nipple, packing, etc. can be reduced.

  Here, it is not always necessary to connect the end portion of the main pipe 101 and the end portion of the connection pipe 102 with a mechanical joint. However, as described above, the end of the main pipe 101 and the end of the connecting pipe 102 can be connected by a mechanical joint because the end of the pipe can be connected without using a connecting tool such as a nipple or packing. preferable.

  Further, as shown in FIGS. 1B and 2B, a dew condensation receiver 5 that receives dew condensation that occurs during cooling is arranged below the pipe 10 (and the panel portion 11). The condensation receiver 5 is formed in a shape that is recessed toward the center side in the thickness direction and the inside in the left-right direction.

  Further, a discharge hole 50 for discharging the flowing dew condensation to the outside of the dew condensation receiver 5 is formed at the most recessed portion of the bottom of the dew condensation receiver 5. A pipe (not shown) is connected to the end of the discharge hole 50 to discharge the dew condensation to the outside.

  The heat dissipation part 1 is formed by disposing a plurality of panel parts 11 on the front surface side and the back surface side of the main pipe 101 (see FIGS. 1A and 3). The panel portion 11 is made of aluminum.

  More specifically, one main pipe 101 extending in the vertical direction is sandwiched between the front panel part 11a and the back panel part 11b to form a part of the panel part 11. Further, a plurality of front panel parts 11a having the same shape are arranged in the left-right direction in a layout corresponding to one main pipe 101 extending in the vertical direction.

  Also, the back side panel portion 11b has a plurality of the same shape in the left-right direction similarly to the front side panel portion 11a. Further, the shapes of the front panel portion 11a and the back panel portion 11b are formed line-symmetrically with respect to the surfaces where both members face each other.

  The front panel portion 11a has a base portion 110 and a plurality of fins 111. The base portion 110 is composed of a pipe coating portion 112 that covers the outer peripheral surface on the front surface side of the main pipe 101 and a plurality of base surfaces 113.

  Further, in the base portion 110 and the plurality of fins 111, several fins 111 and the corresponding base portion 110 are integrally formed to form one fin unit (reference numeral omitted) (FIG. 3). (See (a)). Therefore, the front panel portion 11a is configured by arranging a plurality of fin units along the width direction.

  Further, the back panel part 11b has a base part 114 and a plurality of fins 115. The base portion 114 is composed of a pipe covering portion 116 that covers the outer peripheral surface on the back surface side of the main pipe 101 and a plurality of base surfaces 117.

  Similarly to the front panel portion 11a, with respect to the base portion 114 and the plurality of fins 115, several fins 115 and the corresponding base portion 114 are integrally formed to form one fin unit (reference numeral omitted). ) Is formed. Therefore, the back panel part 11b is configured by arranging a plurality of fin units along the width direction.

  Also, most of the main pipe 101 in the longitudinal direction is sandwiched between the pipe covering portion 112 of the base portion 110 and the pipe covering portion 116 of the base portion 114 via an adhesive (not shown) on the outer peripheral surface thereof, The entire circumference of the main pipe 101 is covered.

  The front panel portion 11a is formed with a plurality of fins 111 protruding from the base surface 113 toward the outer side (front side) in the thickness direction. The back panel portion 11b is formed with a plurality of fins 115 protruding from the base surface 117 toward the outside (back side) in the thickness direction. Further, the positions where the fins 111 and the fins 115 are formed correspond to each other in the left-right direction, and the protruding lengths thereof are also substantially the same.

  In this way, the front panel portion 11a and the back panel portion 111b have a structure in which the main pipe 101 is sandwiched by the pipe covering portion 112 and the pipe covering portion 116, so that the main pipe 101 is circulated between cold and hot water. The front panel part 11a and the back panel part 111b can exchange heat.

  Further, since the front panel portion 11a and the back panel portion 111b are configured by the plurality of base surfaces 113 and 117 and the plurality of fins 111 and 115, the panel portion 11 has an actual surface area and an apparent appearance as a heat radiation portion. The surface area of can be increased.

  Further, although the main pipe 101 is made of stainless steel and the panel portion 11 is made of aluminum, the outer peripheral surface of the main pipe 101 and the pipe covering portion 112 and the pipe covering portion 116 are fixed via an adhesive. Therefore, it is possible to suppress corrosion due to contact of different metals.

  Further, FIG. 6A is a view of one fin 111 (or fin 115) viewed from a direction substantially orthogonal to the thickness direction. As shown in FIG. 6A, a fin taper portion 111a is formed at the lower end portion of the fin 111 and at a part of the outer portion. The fin taper portion 111a is formed in a shape inclined from the outer side to the inner side in the thickness direction and downward.

  With this fin taper portion 111a, even if dew condensation occurs on the outer edge portion of the fin 111 during cooling, the dew condensation can be guided toward the inner side in the thickness direction at the lower end side thereof. That is, the dew condensation is less likely to be scattered outward from the fins 111, and the dew condensation is easily collected in the above-described dew condensation receiver 5. In FIG. 6A, an arrow indicated by a symbol C indicates a direction in which the dew condensation flows in the fin taper portion 111a.

  Here, the front panel section 11a and the back panel section 11b are composed of a plurality of base surfaces and a plurality of fins. The size and number of the base surfaces and the size and number of the fins are the same as those of the structure shown in the radiation panel A. It is not limited to the content. From the viewpoint of increasing the efficiency of radiant heat exchange, it is preferable to combine the base surface and fins to increase the actual surface area and apparent surface area, but the size and number of the base surface should be adjusted according to the space where the radiant panel is installed. Alternatively, the design and size of the fins can be changed as appropriate.

  Further, the radiation panel to which the present invention is applied necessarily employs a structure in which the panel portion 11 is provided on the front surface side and the back surface side, that is, a structure in which the panel portion 11 is provided on both surface sides when viewed from the pipe 10. No need. For example, it is possible to provide the panel portion 11 only on the front surface side and employ the structure of a single-sided radiation panel on the back surface side, which is attached to a wall surface in the room via a heat insulating material.

  The shape of the fins in the radiation panel to which the present invention is applied is not necessarily limited to the shapes of the fins 111 and 115. That is, the shape of the fins is not particularly limited as long as the plurality of fins are formed so as to project outward from the base surface in the thickness direction. However, from the viewpoint of increasing the actual surface area and the apparent surface area, it is preferable that the shape of the fin is substantially rectangular. Further, as described above, by providing the shape of the fin taper portion 111a at the lower end portion of the fin, even if dew condensation occurs on the outer edge portion of the fin during cooling, the dew condensation proceeds toward the inner side in the thickness direction on the lower end side. Therefore, it is preferable that the fin taper portion is provided at the lower end portion of the fin.

  In addition, the base portion 110 (or the base portion 114) and the plurality of fins 111 (or the plurality of fins 115) do not necessarily need to have several fins and a corresponding base portion integrally formed. .. For example, it is possible to manufacture the fin unit by separately manufacturing the base part and each fin and attaching the fins to the base part. However, from the viewpoint of manufacturing labor and cost, in the base portion 110 (or the base portion 114) and the plurality of fins 111 (or the plurality of fins 115), several fins and a corresponding base portion are integrated. Is preferably formed.

  Further, the front panel portion 11a (or the back panel portion 11b) does not necessarily have to be configured by disposing a plurality of fin units along the width direction thereof. For example, without dividing into fin units, one base portion is provided over the entire length in the width direction of the radiation panel A, that is, the entire length in the width direction of the front panel portion 11a (or the back panel portion 11b). A structure in which fins are provided can also be adopted. However, when the length of the radiation panel A in the width direction becomes large, the front panel portion 11a (or the back panel portion 11b) is manufactured in a structure in which a plurality of fin units are arranged along the width direction. It has the advantage of being easy to do.

  Subsequently, the fixing structure of the panel portion that secures the strength by fixing the panel portion 11 will be described with reference to FIGS. 1B and 5. A crosspiece fixing portion 6 and a crosspiece fixing portion 8 for sandwiching and fixing the panel portion 11 from the front surface side and the back surface side are provided on the upper and lower portions of the panel portion 11 (see FIG. 1B).

  As shown in FIG. 5A, a crosspiece fixing portion 6 is provided on the upper side of the panel portion 11. The crosspiece fixing portion 6 is a portion which is provided along the left-right direction of the panel portion 11 and which clamps and fixes the upper end portion of the panel portion 11 from the front surface side and the back surface side.

  The crosspiece fixing portion 6 includes a horizontal crosspiece portion 60 serving as a main body, a reinforcing portion 61 protruding inward in the thickness direction along the upper end of the horizontal crosspiece portion 60, a base surface 113 and a base surface 117 of the panel portion 11. It has a fixing piece 62 which is in contact with the outer peripheral surface and which fixes the panel portion 11 by sandwiching it from the front surface and the back surface side.

  Further, the lower end of the horizontal beam portion 60 and the upper end of the fixed piece 62 are connected by a beam tapered portion 63. The horizontal rail portion 60, the reinforcing portion 61, the rail taper portion 63, and the fixing piece 62 are provided on the upper surface side and the back surface side of the panel portion 11, respectively, and constitute a rail fixing portion 6.

  More specifically, the panel portion 11 is sandwiched, and at the upper end thereof, fixing pieces 62 are provided at regular intervals in the left-right direction, and the panel portion 11 is sandwiched from the front and back sides, via a fastener 62a, The fixing piece 62 fixes the panel portion 11.

  Further, since the horizontal rail portion 60 and the fixing piece 62 are connected via the rail taper portion 63, and the horizontal rail portion 60 is provided in a predetermined length across the left-right direction, the fixed state of the fixing piece 62 is fixed. It is supported by the horizontal cross section 60. Further, since the reinforcing portion 61 protruding inward in the thickness direction is formed from the upper end of the horizontal rail portion 60, the rail fixing portion 6 has a partially bent shape, and the strength of the rail fixing portion 6 is enhanced. ..

  Further, the lower end of the horizontal beam portion 60 and the upper end of the fixed piece 62 are connected by a beam tapered portion 63, and the beam tapered portion 63 is formed to be inclined from the outer side toward the center side in the thickness direction and toward the lower end. .. Due to the cross-section taper portion 63, even if dew condensation occurs on the horizontal cross-section 60 or the reinforcing portion 61 during cooling, the dew condensation can be guided downward and inward in the thickness direction. That is, the dew condensation is less likely to be scattered outward than the crosspiece fixing portion 6, and the dew condensation is easily guided to the center side of the panel portion 11 and collected in the dew condensation receiver 5.

  Further, in the left-right direction, both end portions of the horizontal rail portion 60, that is, a portion connected to the column member 2a or the column member 2b, the horizontal rail portion 60 is L in a direction substantially orthogonal to the longitudinal direction of the horizontal rail portion 60. An L-shaped portion 60a bent into a letter shape is formed (see FIGS. 5A and 5C).

  Further, the heat insulating material 7 is disposed between the inner peripheral surface of the pillar member 2b and the L-shaped portion 60a, and the L-shaped portion 60a sandwiches the heat insulating material 7 and the pillar member 2b (or the pillar member) via the fixture 60b. It is fixed to 2a).

  As a result, both ends of the crosspiece fixing portion 6 are fixed to the pillar members 2a and 2b, and the panel portion 11 and the crosspiece fixing portion 6 are supported via the pillar members 2a and 2b. By disposing the heat insulating material 7 between the pillar member 2b (pillar member 2a) and the L-shaped portion 60a, heat conduction from each member of the beam fixing portion 6 to the pillar member is prevented, and the heat dissipation efficiency in the panel portion 11 is increased. And the occurrence of dew condensation on the pillar member during cooling can be suppressed.

  Further, as shown in FIG. 5B, a crosspiece fixing portion 8 is provided on the lower side of the panel portion 11. The structure of the crosspiece fixing portion 8 is basically the same as that of the crosspiece fixing portion 6 except that the vertical direction is reversed. Therefore, in the following, the structure of the crosspiece fixing portion 8 will be briefly described, and detailed description thereof will be omitted.

  The structure of the crosspiece fixing portion 8 is a portion which is provided along the left-right direction of the panel portion 11 and which holds and fixes the lower end portion of the panel portion 11 from the front surface side and the back surface side.

  The crosspiece fixing portion 8 includes a horizontal crosspiece portion 80, a reinforcing portion 81, and a fixing piece 82 for fixing the panel portion 11 in between. Further, the upper end of the horizontal rail portion 80 and the lower end of the fixed piece 82 are connected by a connecting portion 83. The horizontal rail portion 80, the reinforcing portion 81, the connecting portion 83, and the fixing piece 82 are provided on the upper surface side and the back surface side of the panel portion 11, respectively, and constitute a rail fixing portion 8.

  Further, in the left-right direction, both end portions of the horizontal rail portion 80, that is, a portion connected to the column member 2a or the column member 2b, the horizontal rail portion 80 is L in a direction substantially orthogonal to the longitudinal direction of the horizontal rail portion 80. An L-shaped portion 80a bent into a letter shape is formed (see FIG. 5 (b)).

  Further, a heat insulating material (not shown) is arranged between the inner peripheral surface of the pillar member 2b and the L-shaped portion 80a, and the L-shaped portion 80a is sandwiched with the heat insulating material, and the L-shaped portion 80a is interposed between the pillar members 2b (or It is fixed to the pillar member 2a).

  As a result, both ends of the crosspiece fixing portion 8 are fixed to the pillar members 2a and 2b, and the panel portion 11 and the crosspiece fixing portion 8 are supported via the pillar members 2a and 2b.

  As described above, since the upper and lower portions of the panel portion 11 are sandwiched and fixed by the crosspiece fixing portion 6 and the crosspiece fixing portion 8, a plurality of fins 111 and fins 115 are formed in the panel portion 11, Even if the actual surface area and the apparent area of the panel portion 11 increase, the stability and strength of the entire radiation panel 1 can be ensured.

  Further, since the crosspiece fixing portion 6 and the crosspiece fixing portion 8 sandwich and fix the outer peripheral surfaces of the base surface 113 and the base surface 117 of the panel portion 11 with the fixing pieces 62 and 82, the portions other than the fixing piece 62 are The crosspiece fixing portion 6 and the panel portion 11 do not come into contact with each other. Therefore, for example, as compared with a fixing structure in which a plurality of fins 111 (or fins 115) are directly connected by a plate-shaped member across the left-right direction, dew condensation flows on the crosspiece fixing portion 6 and the crosspiece fixing portion 8, It becomes easy to prevent the dew condensation from scattering on the outside of the panel portion 11.

  As described above, the radiation panel A includes the upper louver 3 and the lower louver 4 that cover the upper and lower pipes 10 of the heat radiating unit 1 and blind them. The upper louver 3 and the lower louver 4 are provided on both front and back surfaces of the heat dissipation panel A.

  FIG. 7A shows a side cross section of the upper louver 3 on one surface side (rear surface). The upper louver 3 is provided outside (on the back surface side) of the fin 115 (or fin 111) and the crosspiece fixing portion 6.

  The upper louver 3 is formed of a member in which a protruding piece 30 for ventilation that protrudes downward to the outside and a blind piece 31 that is connected to the protruding piece 30 for ventilation and that slopes downward toward the inside alternate with each other in the vertical direction. . That is, when viewed from a direction substantially orthogonal to the thickness direction, the shape is such that a step is formed.

  Moreover, the length of the blindfold piece 31 (the length of the inclined surface) is formed longer than the length of the ventilation protruding piece 30 (the length of the inclined surface). The length of the ventilation projection piece 30 and the blind piece 31 in the longitudinal direction is formed to be substantially the same as the width of the heat dissipation portion 1 (see FIG. 1A).

  Further, the ventilation protrusion 30 has a plurality of through holes 30a formed at regular intervals along the longitudinal direction. Due to the formation of the through hole 30a, when a rising air flow (updraft) is generated inside the radiation panel A (inside the upper louver 3) during heating, the through hole 30a is used. The air is easily released to the outside of the upper louver 3.

  As a result, at the time of heating, it is possible to improve the heat exchange rate between the heat radiating unit 1 and the air in the indoor space where the radiation panel A is installed. In addition, in FIG. 7A, the flow of the ascending air current is shown by an arrow with a reference sign Y1.

  In addition, the lower louver 4 is configured by a member in which the ventilation protruding piece 40 protruding outwardly upward and the blind blind piece 41 connected to the ventilation protruding piece 40 and inclined downwardly outward are alternately continuous in the vertical direction. ing. That is, when viewed from a direction substantially orthogonal to the thickness direction, the shape is such that a step is formed.

  Further, the length of the blindfold piece 41 (the length of the inclined surface) is formed longer than the length of the ventilation protruding piece 40 (the length of the inclined surface). Further, the lengths of the ventilation protruding piece 40 and the blindfold piece 41 in the longitudinal direction are formed to be substantially the same as the width of the heat dissipation portion 1 (see FIG. 1A).

  Further, the ventilation protrusion 40 has a plurality of through holes 40a formed at regular intervals along the longitudinal direction. Due to the formation of the through hole 40a, when a descending air flow (downward airflow) occurs inside the radiation panel A (inside the lower louver 4) during cooling, the through hole 40a is used. The structure is such that air can easily escape to the outside of the upper louver 4.

  As a result, it is easy to prevent a phenomenon in which air accumulates inside the heat radiating unit 1 during cooling and dew condensation easily occurs inside the heat radiating unit 1.

  Thus, the upper louver 3 and the lower louver 4 have a structure in which the heat exchange rate of the heat dissipation panel A is improved and the occurrence of dew condensation is easily suppressed by forming the step shape and the through hole. In addition, in FIG.7 (b), the flow of a downdraft is shown by the arrow which attached | subjected the code | symbol Y2.

  FIG. 8 shows the internal structure of the pillar members 2a and 2b. As shown in FIG. 8, the pillar member 2b (pillar member 2a) is composed of a pillar body 20 and a cover body 21 that is detachable from the pillar body 20.

  Further, in a state where the cover body 21 is attached to the pillar body 20 from the outside (the arrow X in FIG. 8 indicates the attachment direction of the cover body 21), there is a gap between the outer peripheral surface 20a of the pillar body and the cover body 21a. Are formed.

  In this way, a gap is formed between the outer peripheral surface 20a of the column body and the cover body 21a, so that a heat insulating material can be separately placed in the gap. During cooling, dew condensation may occur in the space inside the pillar member 2a (or the pillar member 2b), causing dew condensation on the floor surface on which the radiation panel A is installed, and water may drop. Further, it is possible to suppress the occurrence of dew condensation inside the pillar member.

  As described above, in the radiation panel A to which the present invention is applied, a plurality of panel portions 11 of the heat dissipation portion 1 are formed on the front surface side and the back surface side, and each front panel portion 11a and back panel portion 11b serves as a base portion. By being composed of a plurality of fins, it is possible to increase the actual surface area and the apparent surface area as the heat dissipation portion. Therefore, the structure has an excellent cooling and heating effect by radiation heat radiation and convection heat radiation.

  Further, the panel portion 11 is sandwiched and fixed from the front surface side and the back surface side by the crosspiece fixing portions 6 and 8 provided on the upper and lower portions, thereby suppressing the flow of dew condensation on the crosspiece fixing portion 6 and the like. Above, a strong structure can be obtained.

  Further, in the radiation panel A, by providing the crosspiece fixing portion 6 and the fins 111 and 115 with a tapered shape, it is possible to suppress the scattering of dew condensation to the outside of the panel portion 11.

  Further, by forming the step shape and the through hole of the upper louver 3 and the lower louver 4, it is possible to improve the heat exchange rate and suppress the occurrence of dew condensation by utilizing the flow of air.

  As described above, the radiant panel of the present invention is excellent in cooling and heating effect, and is capable of sufficiently treating the generated dew condensation as to the radiant panel used for radiant cooling and heating.

  Although the invention made by the inventor has been specifically described based on the embodiment, the invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.
