Description

[Detailed description of the invention] 【Technical field】

The present invention relates to the structure of a joint portion of a thin heat exchange panel that allows heat exchange by passing a fluid inside the panel.

[Background technology]

In the joint portion of this type of heat exchange panel, the mutual adhesion between the joint and the heat exchange panel is extremely important, and if the adhesion is poor, it is extremely difficult to perform thermal fusion. In particular, as shown in FIG.
If the end faces on both sides of the inlet 2 and outlet 3 are uneven (shown slightly exaggerated in Fig. 4), there may be fusion between the shoulder of the joint 4 and the end face of the heat exchange panel 1. There was a problem in that defects were likely to occur, and when defective fusion occurred, water was likely to leak from the gap δ. In addition, if the partition part 5 of the joint 4 is not completely fused to the heat exchange panel 1, mixing of fluids will occur.
This results in a decrease in heat exchange efficiency, and for this reason, it must be positioned at the center between the outlet 3 and the inlet 2. Conventionally, this positioning has been done using a jig, which is time-consuming.

[Purpose of the invention]

The present invention was made in view of the above-mentioned technical background, and its purpose is to ensure watertightness between the heat exchange panel and the joint, and to facilitate the positioning of the joint. The aim is to make it possible to do so.

[Disclosure of the invention]

The structure of the joint part of the heat exchange panel of the present invention is such that a fluid inlet 2 and an outlet 3 are provided at the ends of a thin heat exchange panel 1 that allows fluid to be passed through and exchanged heat.
The joint 4 is attached to the heat exchange panel 1 so as to cover the inlet 2 and the outlet 3 in a watertight manner, and the inlet 2 and the outlet 3 are sealed in the joint 4 in a watertight manner. A partition part 5 is provided to partition the heat exchange panel 1 between the inlet 2 and the outlet 3, and the middle and both outer sides.
A protrusion 6 for preventing water leakage is provided on one of the tip and both ends of the partition 5 in the joint 4, and a recess 7 is provided on the other, and the protrusion 6 and the recess 7 are fitted into each other. This is a characteristic feature of the invention, and the above objective has been achieved. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Reference numeral 1 denotes a heat exchange panel, in which a double-layered fabric is disposed between an upper resin layer and a lower resin layer to form a fluid flow path therein. Such a heat exchange panel 1 may be flexible or rigid. Approximately at the center of the heat exchange panel 1, a flow path is divided into left and right sides by a central rib 8.
The heat exchange panel 1 is provided with rectangular notches 9 at both ends thereof, and a connecting body 10 for connecting the left and right channels is attached to the rear notch 9. As shown in FIG. 1, the front notch 9 has a fluid inlet 2 and an outlet 3 opened on both left and right sides thereof. Furthermore, a recess 7 is cut out at the end of the central rib 8 within the cutout 9, and a recess 7 is also cut out at both shoulder portions of the cutout 9.
The joint 4 is made of synthetic resin and is connected to the heat exchange panel 1 from the front and back.
It is formed into a substantially U-shaped cross section so that the vicinity of the notch 9 can be sandwiched, and a partition 5 is provided at the center of the joint 4 to partition the inside of the joint 4 into left and right sides. An inflow side nozzle 11 and an outflow side nozzle 12 protrude from the left and right sides of 5, and are approximately plate-shaped in plan view. Furthermore, protrusions 6 are protruded within the joint 4 at the tip of the partition 5 and on both sides of the partition 5 in correspondence with the recess 7 of the heat exchange panel 1. Then, the vicinity of the notch 9 of the heat exchange panel 1 is sandwiched between the joints 4, and the protrusions 6 on both sides of the joint 4 are fitted into the recesses 7 on the shoulders of the heat exchange panel 1 to position the joint 4, and the partition part Position the partition portion 5 by fitting the protrusion 6 at the tip of 5 into the recess 7 at the center,
In this state, the peripheral edge of the joint 4 and the heat exchange panel 1 are thermally welded and sealed by pressing with a heat press or the like from above and below. By doing this, even if there is a gap between the heat exchange panel 1 and the joint 4, if the length is less than the length of the protrusion 6, the tip of the partition 5 will be connected to the protrusion 6.
The fitting between the recess 7 and the recess 7 ensures a reliable seal and no mixing of fluids, and the fitting between the recess 7 and the protrusion 6 of the shoulder prevents water from leaking from the inlet 2 or the outlet 3. The heat exchange panel 1 configured as described above is used as a floor heating panel by laying it on the floor, for example, and a fluid feed pipe such as hot water is connected to the nozzle 11 on the inflow side of the joint 4, and the outflow side nozzle 1
A fluid return pipe is connected to 2. Therefore, joint 4
Fluid flows in from the nozzle 11, spreads uniformly from the inlet 2 into one channel partitioned by the central rib 8, passes through the connecting body 10, and flows uniformly into the other channel partitioned by the central rib 8. It goes out from the outlet 3 through the nozzle 12, and is radiated from the heat exchange panel 1 to provide heating.

【Effect of the invention】

Since the present invention is configured as described above, even if there is a gap between the joint and the heat exchange panel, the gap between the joint and the heat exchange panel can be reliably closed by fitting the protrusion and the recess. This has the advantage of reliably preventing water leakage and fluid mixing. Furthermore, there is an advantage that the fitting between the protrusion and the recess allows the joint to be reliably and easily positioned on the heat exchange panel.
