Description

The present invention relates to a method for manufacturing a heat dissipation panel used for a temperature control panel for floor heating and the like, and a jig used for the manufacture.

A floor heating structure in which a temperature control panel in which a hot water pipe is routed in a groove on the upper surface of a plate-shaped substrate is laid on the floor is well known.

The temperature control panel is made of aluminum foil or the like so as to cover the grooves after the hot water pipes are routed in the grooves of a substantially rectangular substrate having a plurality of grooves for arranging the hot water pipes on the upper surface. The sheet is pasted.

FIG. 4 is an enlarged view of a part of the temperature control panel described in Patent Document 1, and FIG. 5 is an enlarged sectional view taken along line VV of FIG. In FIGS. 4 and 5, the heat dissipation sheet is not shown.

The temperature control panel 1 of FIG. 4 has a rectangular main substrate A and auxiliary substrates B, C, D, E, F and the like along the short side portion of the main substrate A. In the main board A, the groove 2 extends linearly in the longitudinal direction of the main board A. In the sub-boards B to F, the groove 3 is curved.

In the sub-board C, each groove 3 extends in a substantially U-shape so as to connect the grooves 2 and 2 of the adjacent main boards A and A.

As shown in FIG. 5, a heat transfer member made of aluminum, copper, or the like called a heat soaking sheet 4 is mounted in the groove 2 of the main heat dissipation panel. As shown in FIG. 6, the heat soaking sheet 4 has a U-shaped cross-sectional portion 4a and a flange portion 4b projecting from both ends of the U-shaped cross-sectional portion 4a in opposite directions. The heat equalizing sheet 4 is for efficiently transferring the heat of the hot water pipe 5 to the upper surface of the temperature control panel 1.

In the sub-boards B to F, since the groove 3 is curved, the linear heat equalizing sheet 4 shown in FIG. 6 cannot be mounted. Therefore, as shown in FIG. 7, for the aluminum sheet 7 pasted on the surface of the grooved substrate B, a cut is made in the aluminum sheet 7 along the groove 3 by a cutter or the like, and then the portion along the cut is made with a fingertip. The flap 7a is pushed into the groove 3 so as to be along the side wall surface of the groove 3. Since this work is performed manually by a worker, it takes time and effort to manufacture a substrate for a temperature control panel.

An object of the present invention is to provide a method capable of easily manufacturing a heat radiating panel used for a temperature control panel or the like, and a jig for that purpose.

The jig for manufacturing a heat dissipation panel of the present invention has a heat transfer sheet of a substrate with a heat transfer sheet having a substrate having a groove and a heat transfer sheet attached to a surface having the groove of the substrate as a groove. A jig for manufacturing a heat-dissipating panel for cutting along and pushing the generated flap into the groove, on the base plate, the blade provided on the base plate according to the groove pattern, and both side surfaces of the blade. It has a push-in piece provided along it for pushing the resulting flap into the groove.

In one aspect of the present invention, the push-in piece is made of rubber or synthetic resin.

In one aspect of the invention, the blade is saw blade-shaped.

In one aspect of the present invention, the base plate is provided with a stopper for positioning the substrate.

In the method for manufacturing a heat transfer panel of the present invention, a substrate with a heat transfer sheet is placed on the jig for manufacturing the heat transfer panel of the present invention, the substrate is pressed to cut the heat transfer sheet, and the generated flap is in the groove. Has a step of pushing into.

According to the jig of the present invention, a substrate with a heat transfer sheet is placed on the jig with the heat transfer sheet facing the jig, and the substrate is pressed (including tapping) to cut the heat transfer sheet. Can be easily pushed into the groove of the substrate. Further, when this jig is used, the quality of the manufactured substrate with a heat transfer sheet is less likely to vary, and the heat transfer characteristics of the substrate with a heat transfer sheet are stable.

In the present invention, by preparing a jig having a blade having a shape that imitates the groove of the substrate, it is possible to easily process (push the flap) the substrate with the heat transfer sheet having various groove patterns.

It is a perspective view which shows the manufacturing method of the heat dissipation panel which concerns on embodiment. FIG. 2 is a sectional view taken along line II-II of FIG. FIG. 2 is a sectional view taken along line III-III of FIG. It is a top view of the temperature control panel. FIG. 4 is a sectional view taken along line VV of FIG. It is a perspective view of a heat soaking sheet. It is a perspective view of the substrate B. It is a perspective view of the substrate B with an aluminum sheet. It is sectional drawing of the substrate B with an aluminum sheet.

Hereinafter, embodiments will be described with reference to FIGS. 1 and 2. In this embodiment, the substrate B with the aluminum sheet 7 shown in FIG. 9 will be described as an example of the heat dissipation panel, but a high heat transfer sheet such as a copper sheet may be used instead of the aluminum sheet. Further, instead of the substrate B, a substrate having grooves of various shapes such as the substrates C, D, E, and F may be used.

The jig 10 has a base plate 11, a blade unit 12 provided on the base plate 11, and a stopper 13 for positioning the substrate B. As shown in FIG. 2, the blade unit 12 includes a thin plate-shaped blade 14 and push pieces 15 arranged along both side surfaces of the blade 14. The thin plate-shaped blade 14 is erected vertically from the upper surface of the base plate 11. The upper end of the blade 14 has a saw blade shape as shown in FIG. The blade 14 is made of metal in this embodiment, but is not limited thereto.

The blade unit 12 is provided with a pattern that matches the arrangement pattern of the groove 3 of the substrate B. The stopper 13 is installed on the base plate 11 in a positional relationship along the outer side of the substrate B.

In order to process the substrate B with the aluminum sheet 7 using this jig 10 to manufacture a heat dissipation panel, the substrate B is placed on the jig 10 so that the aluminum sheet 7 faces downward as shown in FIG. .. At this time, the edge of the substrate B is brought into contact with the stopper 13 for positioning. In this state, each blade unit 12 is overlapped with each groove 3 via the aluminum sheet 7.

Therefore, the substrate B is strongly pressed downward, the blade unit 12 is pushed into the groove 3, the aluminum sheet 7 is cut by the blade 14, and the flap 7a generated by the push piece 15 is pushed into the groove 3, as shown in FIG. The flap 7a is placed along the side wall surface of the groove 3. In order to press the substrate B downward, it is convenient and preferable to hit the substrate B with a tapping tool such as a rubber hammer, but a press machine or the like may also be used. When hitting with a rubber hammer or the like, it is preferable to stack a backing plate on the substrate B and hit it from above.

After that, by separating the substrate B from the jig 10, a heat dissipation panel made of the substrate B with an aluminum sheet in which the flap 7a is along the side wall surface of the groove 3 can be obtained.

If the material of the push-in piece 15 is too hard, the substrate B will be deformed or the aluminum sheet 7 will be damaged when the substrate B is pressed. On the contrary, if the material of the push piece 15 is too soft, there arises a problem that the flap 7a does not follow the side wall surface of the groove 3. For this reason, the push piece 15 is preferably made of a material having predetermined flexibility, such as a synthetic resin sponge or rubber.

Since the stopper 13 is temporarily fixed to the base plate with an adhesive, the positioning can be easily changed according to the shape of the substrate B. Further, it is preferable to use a rubber material for the stopper 13 in order to prevent deformation when the substrate B is pressed.

The type of the blade 14 is not particularly limited, and examples thereof include a straight blade, a sewing machine blade, and a saw blade. Above all, the saw blade is preferable because it easily bites into the aluminum sheet 7 and it is easy to cut the aluminum sheet 7.

In the above embodiment, the upper surface of the push piece 15 is horizontal, but it may be an inclined surface that becomes higher as it approaches the blade 14.

The above description is an example of the present invention, and the present invention is not limited to the above description, and may be an embodiment other than the above.
