BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0016]
FIG. 1 is an assembled plan view of a heating system according to an embodiment of the present invention, and FIG. 2 is an enlarged view of a connection member shown in FIG. 1. The heating system has an internal space through which a heating fluid flows, that is, a cavity (not shown). And a plurality of connecting members 4 that integrally connect the plurality of heating panels 2 to provide a fluid path between the heating panels 2.
[0017]
Here, each heating panel 2 is made of a thermoplastic plastic, which is easier to manufacture and mold than a metal pipe structure, is formed in a plate shape, and the heating fluid flowing inside the heating panel 2 has a larger area. Over the building floor (or wall or ceiling).
[0018]
In the present embodiment, the heating panel 2 has, for example, a rectangular structure having a pair of long sides and short sides, and each heating panel 2 is provided with a heating at two corners opposed in any one diagonal direction. Two fluid connection portions 6 for supplying and discharging the fluid are formed.
[0019]
Each heating panel 2 is continuously arranged so that any one of the fluid connection portions 6 faces the fluid connection portion 6 of the adjacent heating panel 2, and two fluid connections are provided between the heating panels 2. The connecting member 4 for integrally connecting the connecting portion 6 is provided.
[0020]
As shown in FIG. 2, the connecting member 4 is composed of a central connecting pipe 8 and a pair of elbow (elbow) members 10 assembled at both ends of the connecting pipe 8. The elbow-shaped member 10 made larger than the outer diameter of the connecting portion 6 is fitted to the connecting pipe 8 and the outer peripheral surface of the fluid connecting portion 6. The elbow-shaped member 10 is made of a thermoplastic plastic like the heating panel 2 and is integrated with the heating panel 2 during the heat fusion process while surrounding the fluid connection part 6 when assembling the heating system. So that it can be assembled.
[0021]
Therefore, the heating fluid provided at the inlet of the heating system sequentially passes through the plurality of heating panels 2 by the connecting member 4 and is discharged to the outlet of the heating system, and the flow direction of the heating fluid is indicated by a dotted arrow in the drawing. .
[0022]
In such an assembled heating system, each heating panel 2 controls the flow of the heating fluid smoothly so that the heating fluid does not concentrate or stagnate in a specific portion in consideration of the thermal efficiency of the heating system. It is very important to keep the temperature distribution of No. 2 uniform.
[0023]
FIG. 3 is a perspective view of a heating panel according to a first embodiment of the present invention, FIG. 4 is a partially enlarged view of FIG. 3 for explaining a support member, and FIG. 5 is a view for explaining the inside of the heating panel. FIG. 4 is a sectional view taken along line AA of FIG. 3.
[0024]
As shown, the heating panel 2 has upper and lower plates 14, 16 facing each other so as to have an internal cavity 12, and has a predetermined area and an interval between the upper and lower plates 14, 16 to form an upper and lower plate. It includes a plurality of support members 18 connecting the plates 14 and 16, and two fluid connection portions 6 for supplying and discharging the heating fluid.
[0025]
The support member 18 preferably comprises a pair of recesses 20 extending at each of the upper and lower plates 14, 16 toward the other plate and connecting the upper and lower plates 14, 16.
[0026]
Such a support member 18 prevents deformation of the upper and lower plates 14 and 16 due to an external force, and provides a cavity 12 through which the heating fluid flows between the plurality of support members 18. Therefore, the heating fluid supplied to any one of the fluid connection portions 6 flows through the cavity 12 between the upper and lower plates 14 and 16 and transfers heat to the outside of the upper plate 14 as indicated by a dotted arrow in FIG. Become like
[0027]
The support member 18 also provides resistance to the flow of the heating fluid so that the heating fluid is uniformly distributed inside the heating panel 2, but the flow of the heating fluid supplied to the heating panel 2 is controlled by the support member 18. Are greatly affected by the diameter, spacing, and arrangement of the elements.
[0028]
In this embodiment, the support member 18 is formed in a circular shape having a predetermined diameter, and has a horizontal axis (x-axis in the drawing) parallel to the long side of the heating panel 2 and a vertical axis parallel to the short side of the heating panel 2. It has regularity that is arranged side by side at predetermined intervals along the axis (y-axis in the drawing) direction. Preferably, the distances D1 and D2 between the support members 18 facing each other along the horizontal axis and the vertical axis are the same as the diameter D of the support members 18.
[0029]
As an example, the fluid connection part 6 for supplying and discharging the heating fluid has a center axis (z axis in the drawing) of the fluid connection part 6 at an angle of approximately 45 ° with respect to either side of the upper and lower plates 14 and 16. Is provided. Accordingly, the flow of the heating fluid supplied through one of the fluid connection portions 6 is dispersed by the plurality of support members 18 facing the fluid connection portion 6 and flows inside the heating panel 2.
[0030]
In particular, in this embodiment, a dispersing member for dispersing the flow of the fluid is formed facing the fluid connection part 6 to which the heating fluid is supplied or discharged. 6 and 7 are partially enlarged views of the heating panel of FIG. 3, in which the support member 18 and the dispersing members 22 and 24 are hatched for the sake of convenience.
[0031]
Preferably, the dispersing members 22, 24 are extended toward the other one of the upper and lower plates 14, 16 similarly to the support member 18 so as to extend from the pair of recesses 20 connecting the upper and lower plates 14, 16. Become.
[0032]
As shown in the figure, since the plurality of support members 18 are arranged at regular intervals along the horizontal axis and the vertical axis direction of the heating panel 2, the internal cavity through which the heating fluid flows also has the fluid connection portion. Are set continuously along the horizontal axis and vertical axis direction of the drawing.
[0033]
At this time, the heating panel 2 disposes the first dispersion member 22 at one point of a cavity (the center position is indicated by an imaginary D line) that faces the fluid connection part 6 and continues in the horizontal axis direction. The second dispersion member 24 is disposed at one point of the cavity (the center position is indicated by a virtual E line) that faces the vertical direction and faces the space 6.
[0034]
Therefore, the first dispersing member 22 does not coincide with the center position of the other supporting members 18 along the horizontal axis direction of the heating panel 2, and the second dispersing member 24 also extends along the vertical axis direction of the heating panel 2. It has an arrangement structure in which the center position does not coincide with the other support members 18.
[0035]
Therefore, the first and second dispersing members 22 and 24 (corresponding to the virtual D line and E line, respectively) block the continuous cavity from directly continuing with the fluid connection part 6 and the heating fluid is connected to the continuous cavity. Disperse what is concentrated in the cavity.
[0036]
More specifically, a plurality of the support members 18 are continuously arranged along the horizontal axis and the vertical axis direction (x-axis direction and y-axis direction) of the heating panel 2, and A plurality of support members arranged in a line along a central axis (z axis in the drawing) are arranged in a line, and among a plurality of support members 18 arranged along the central axis of the fluid connection portion 6, a support member closest to the fluid connection portion 6 Assuming that the first support member 26 is used, the first and second dispersion members 22 and 24 are provided at a position where the heating fluid is supplied and the flow is separated by the first support member 26.
[0037]
That is, the first dispersion member 22 is the first continuous cavity in which the flow of the fluid hitting the first support member 26 is separated in the horizontal axis direction, that is, one point on the first virtual line (indicated by a chain line D in the drawing). And the second dispersion member 24 is located on the first continuous cavity where the flow of the fluid impinging on the first support member 26 is separated in the vertical axis direction, that is, on the second imaginary line (indicated by an E-chain line in the drawing). Located at one point.
[0038]
In particular, looking at the positional relationship between the first support member 26 and the first and second dispersion members 22 and 24 with reference to FIG. 6, a tangent line connecting the first support member 26 and the first dispersion member 22 (see FIG. In this case, a tangent connecting the first support member 26 and the second dispersing member 24 (indicated by a dotted line in the drawing) is parallel to the vertical axis of the heating panel 2. It can be seen that the two tangents are parallel and perpendicular to each other with the first support member 26 as the vertex.
[0039]
According to the above configuration, as shown in FIG. 7, the heating fluid provided inside the heating panel 2 along the central axis of the fluid connection portion 6 first strikes the first support member 26 and the flow thereof is in the horizontal axis direction. Separated in the vertical axis direction.
[0040]
Then, the flow of the fluid separated in the horizontal axis direction is again separated in the vertical direction by the first dispersion member 22, the flow of the fluid in the horizontal axis direction is dispersed, and the flow of the fluid separated in the vertical axis direction is The fluid is separated in the left-right direction again (in the drawing) by the two dispersion members 24 and the fluid flow in the vertical axis direction is dispersed. Further, the flow of the fluid separated by the first and second dispersion members 22 and 24 is again dispersed by the plurality of support members 18 that are continuously set along the horizontal axis and the vertical axis direction of the heating panel 2. .
[0041]
As described above, the heating panel 2 having the above-described internal structure allows the first and second dispersion members 22 and 24 to re-distribute the flow of the heating fluid separated through the first support member 26 in the horizontal axis direction and the vertical axis direction. Accordingly, the heating fluid provided to the fluid connection unit 6 is more uniformly distributed inside the heating panel 2.
[0042]
On the other hand, the heating panel 2 has the first and second dispersing members 22 and 24 disposed at two corners facing the fluid connection portion 6 and at the same time, the other two corner portions where the fluid connection portion 6 is not located. May be provided with a guide channel.
[0043]
FIG. 8 is a perspective view of a heating panel according to a second embodiment of the present invention. FIG. 9 is a partially enlarged view of FIG. 8 for explaining a guide channel. The first and second guide channels 28 and 30 are formed in place of the support member 18 at the other two corners where is not located.
[0044]
The first and second guide channels 28 and 30 are extended from each of the upper and lower plates 14 and 16 to the other plate in the same manner as the support member 18 to connect a pair of recesses to connect the upper and lower plates 14 and 16. A predetermined width and length along a horizontal axis (X axis in the drawing) and a vertical axis (Y axis in the drawing) direction of the heating panel 2 ′ at a fixed distance from a corner of the heating panel 2 ′. Formed.
[0045]
Preferably, each guide channel 28, 30 has the same width (W) as the diameter (D) of the support member 18, and the length (L) of the guide channel 28 along the horizontal and vertical axes is 3 The diameter is approximately 6 to 10 times the diameter (D) of the support member 18, which is the same as that obtained by integrally connecting up to five support members 18.
[0046]
The first and second guide channels 28 and 30 reduce the resistance of the heating fluid at the corners of the heating panel 2 'to increase the flow rate of the heating fluid, thereby discharging the heating fluid. Plays the role of guiding in the direction. Therefore, the heating panel 2 'having the first and second guide channels 28 and 30 has a uniform temperature distribution over the entire heating panel 2' because the heating fluid does not stagnate at the corners and the generation of bubbles due to the warm current is suppressed. It has advantages.
[0047]
On the other hand, the preferred aspect ratio (the ratio of the long side to the short side of the heating panel) in the rectangular heating panel 2 considering the flow of the heating fluid is preferably in the range of 1.5: 1 to 3: 1.
[0048]
This is because the center axis of the fluid connection part 6 is almost set at an angle of 45 ° with respect to the long and short sides of the heating panel 2 in consideration of the symmetry of the connecting member 4, but the heating panel 2 has a square structure. Is formed, the flow of the heating fluid is concentrated in a diagonal direction connecting the two fluid connection portions, and it is difficult to uniformly distribute the flow of the heating fluid inside the heating panel 2.
[0049]
In addition, as shown in FIGS. 10 and 11, the heating panel 2 ″ may be formed in a polygonal structure such as a hexagonal or octagonal structure in addition to the above-described rectangular structure. A continuous arrangement of 2 "can be made easier.
[0050]
On the other hand, the heating panel 2 minimizes the heat loss of the heating panel 2 and compensates for the difference in height of the fluid connection part 6 with respect to the upper and lower plates 14 and 16 as shown in FIG. A heat insulating layer 32, more specifically, a styrofoam layer is formed on the bottom surface of the building to further facilitate the installation of the heating panel 2 on the building floor.
[0051]
【The invention's effect】
Thus, the present invention provides the heating panel with a plurality of support members, a dispersing member, and a guide channel, thereby distributing the heating fluid supplied to the heating panel more evenly, thereby making the temperature distribution of the heating panel uniform, The heating fluid flows more smoothly through the entire heating panel including the corners, thereby improving heat transfer efficiency.
