Description

[Detailed description of the invention] [Technical field] This invention relates to a heat exchange panel used for floor heating and the like.

[Background technology]

In recent years, heat exchange panels with excellent lightness and flexibility have been developed, as shown in FIG. , 1', and a triple-layered fabric 3 forming a flow path section 2 has been developed. The triple structure fabric 3 includes a sheet-like fabric portion 3a bonded to the front material 1, and a back material 1'.
A wavy vertical monofilament 3c 1 and a linear monofilament sandwiched between and bonded to both sheet-like fabric portions 3a and 3b to form the flow path portion ₂ . It consists of a thick intermediate fabric part 3c woven with horizontal filaments _3c2 .

In such a heat exchange panel, the resistance given to the fluid (gas, liquid) differs greatly between the A direction and the B direction of the fluid flow direction due to the weaving method of the thick intermediate fabric portion 3c. That is, the resistance is small in the direction A along the horizontal monofilament _3c2 , and the resistance is large in the direction B, which intersects (perpendicularly intersects in the illustrated case) with the horizontal monofilament 3c2.

By the way, heat exchange panels are generally provided with partitions from the inlet to the outlet of the fluid, so that the fluid flows evenly throughout the panel and the temperature distribution is even and uniform. However, in the recently developed heat exchange panel equipped with the above-mentioned triple structure fabric 3, the resistance to flow differs greatly depending on the flow direction, so if sufficient attention is not paid to how to partition the flow channels, the fluid flow may become uneven. As a result, there is a possibility that the temperature distribution becomes non-uniform. Further, in some cases, pressure loss becomes large, requiring the use of a circulation pump with a large capacity, and power consumption also increases.

[Purpose of invention]

The purpose of this idea is to solve the above problem.
To provide a heat exchange panel in which fluid flow and temperature distribution can be made uniform by devising a way of partitioning the flow passages in which the flow passages are made of a fabric whose resistance to flow differs depending on the direction.

[Disclosure of invention]

The heat exchange panel of this invention has a sheet-like double-sided material, and a flow path section that is sandwiched between these double-sided materials to connect them, and has different resistance to flow in one direction and in a direction crossing the two-sided materials. In a heat exchange panel including a fabric to be formed and an inlet and an outlet for the flow passage section, in forming a series of flow passages having a width smaller than the panel width from the inlet to the outlet with a partition, the resistance The segmented flow path along the direction where resistance is large is made longer than the segmented flow path along the direction where resistance is small.

Before explaining the embodiment of this invention, a comparative example thereof will be explained with reference to FIG. This heat exchange panel has a structure similar to that shown in FIG. A partition consisting of a partition 6b extending along the B direction with high resistance through the partition 6b, and a partition 6a continuous with the end of this partition 6b (located approximately at the center of the panel width) along the A direction with low resistance. A section 6 is provided. The entire periphery of the panel is sealed. In the case of this comparative example, the flow R tends to concentrate near the partition part 6a along the A direction where the resistance is low, and there is little or no flow near the both end sides 7a and 7b of the panel, and as a result, There is a drawback that temperature unevenness occurs throughout the panel.

Next, an embodiment of this invention will be explained based on FIG. This heat exchange panel has a structure similar to that shown in Fig. 1, and an inlet 4 and an outlet 5 are separated from each other in a direction B that intersects (perpendicularly intersects) with a direction A where flow resistance is low at one corner of the panel. There is a partition 8b that passes between the inlet 4 and the exit 5 and runs in the A direction with low resistance, and a partition 8b that runs along the A direction with low resistance and continues with the end of this partition 8b (located approximately at the center of the panel width) and runs in the A direction with low resistance. A partition section 8 is provided, which is composed of a partition section 8a extending in the intersecting (perpendicular) direction B. The entire perimeter of the panel is sealed.

The fluid flowing in from the inlet 4 first flows in the direction A where the resistance is low, sufficiently filling one tunnel-shaped space formed by the corrugated vertical monofilament 3c ₁ and the straight horizontal monofilament 3c ₂ , and then flowing into the next tunnel. It flows into a tunnel-like space, fills this space, and then moves on to the next tunnel-like space (see the dashed-dotted arrow). Therefore, the fluid flow R is uniform throughout the entire flow path. That is, the flow is substantially uniform not only near the partitions 8, 8a, and 8b, but also near both end sides 7a, 7b of the panel, and all other locations, resulting in a uniform temperature distribution over the entire panel.

In addition, in this embodiment, the panel width W in the A direction is B
It is suitable for areas where the panel depth L in the direction is smaller. The inlet 4 and outlet 5 may be used interchangeably.

Partitions 8, 8a, 8 as shown in A to D in Figure 4
The one provided with b is also an embodiment of this invention. In addition, this invention has sheet-like fabric parts 3a, 3 on the front and back sides.
It also includes a case in which b is omitted and the thick intermediate fabric portion 3c is directly connected to the front and back surfaces 1 and 1'.

In addition, in a heat exchange panel in which the inlet 4 and the outlet 5 are arranged side by side at one corner of the panel P, two of the connectors 10 provided at the end of the fluid tube 9 are connected to the inlet 4 and the outlet 5 as shown in FIG. It is adhered to the outlet 5, and both connectors 10, 10 are covered with a protective cover 11. In addition, when connecting two heat exchange panels, as shown in _FIG .
and the inlet 4 of the other panel P ₂ ,
Connector 10a, connection tube 9a, connector 1
0a (in the case of series connection, see Fig. 6A), the inlets 4, 4 and the outlet 5,
Bifurcated connector 10 for connecting 5 to each other
b, a connecting body consisting of a connecting tube 9a and a connector 10a (in the case of parallel connection; see FIG. 6B). In both cases of FIGS. 6A and 6B, large protective covers are used for the four connectors.

Figure 7 shows an improved version of the one in Figure 5. A leak-proof reinforcing member 13 with two holes 12 formed therein and a tube 15 forming two recesses 14 and communicating with each recess 14.
A connected body is constituted by the block 16 holding the. First, the reinforcing material 13 is bonded to the panel P so that the holes 12, 12 are aligned with the inlet 4 and the outlet 5 to prevent fluid leakage. Next, block 16 is attached to reinforcing material 1.
Glue to 3. Since the bonding area between the reinforcing material 13 and the panel P is large, leakage can be prevented more reliably than in the case shown in FIG. 5, and peeling of the two can be reliably prevented. It has fewer parts than the one in Figure 5 and is easier to assemble, and since the block 16 serves as both the channel forming part and the cover 11 in Figure 5, it has a good appearance and is resistant to being stepped on. However, the thickness of the panel connection part can be reduced.

A and B in Fig. 8 are improved versions of A and B in Fig. 6, respectively, and the structure is basically the same as that in Fig. 7, so the same parts will be given the same reference numerals and will only be explained. will be omitted. The advantages of these improvements are also similar to those of FIG.
