  In the sub-substrates B to F, since the groove 3 is curved, it is not possible to mount the straight heat equalizing sheet 4 shown in FIG. Therefore, as shown in FIG. 7, the aluminum sheet 7 is pasted on the surface of the substrate B with the groove, and the aluminum sheet 7 is cut along the groove 3 with a cutter or the like. Is pushed into the groove 3 so that the flap 7a is aligned with the side wall surface of the groove 3. Since this operation is performed manually by an operator, it takes time to manufacture the temperature control panel substrate.

  An object of this invention is to provide the method and jig | tool for it which can manufacture easily the heat radiating panel used for a temperature control panel etc.

  The jig for manufacturing a heat radiating panel of the present invention uses the heat transfer sheet of the substrate with the heat transfer sheet as a groove, which includes a substrate having a groove and a heat transfer sheet attached to the surface having the groove of the substrate. A heat radiating panel manufacturing jig for cutting along the groove and pushing the generated flap into the groove, and a base plate, a blade provided on the base plate in accordance with the groove pattern, and both sides of the blade And a pushing piece for pushing the resulting flap into the groove.

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

  In one aspect of the invention, the blade is sawtooth shaped.

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

  The manufacturing method of the heat radiating panel of the present invention includes stacking a substrate with a heat transfer sheet on the jig for manufacturing the heat radiating panel of the present invention, pressing the substrate to cleave the heat transfer sheet, and forming the generated flap in the groove. The process of pushing into.

  According to the jig of the present invention, the substrate with the heat transfer sheet is stacked on the jig with the heat transfer sheet facing the jig, and the substrate is pressed (including tapping) to cleave the heat transfer sheet. Can be easily pushed into the groove of the substrate. Moreover, when this jig is used, there will be little variation in the quality of the manufactured substrate with a heat transfer sheet, and the heat transfer characteristics of the substrate with a heat transfer sheet will be stable.

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

It is a perspective view which shows the manufacturing method of the thermal radiation panel which concerns on embodiment. It is the II-II sectional view taken on the line of FIG. It is the III-III sectional view taken on the line of FIG. It is a top view of a temperature control panel. It is the VV sectional view taken on the line of FIG. It is a perspective view of a soaking sheet. 3 is a perspective view of a substrate B. FIG. It is a perspective view of the board | substrate B with an aluminum sheet. It is sectional drawing of the board | substrate B with an aluminum sheet.

  Hereinafter, embodiments will be described with reference to FIGS. In this embodiment, the substrate B with the aluminum sheet 7 shown in FIG. 9 will be described as an example of the heat radiating 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 includes 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-like blade 14 and pushing pieces 15 arranged along both side surfaces of the blade 14. The thin 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 in a pattern that matches the arrangement pattern of the grooves 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 manufacture the heat dissipation panel by processing the substrate B with the aluminum sheet 7 using the jig 10, the substrate B is stacked 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 to perform 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 generated flap 7a is pushed into the groove 3 by the pushing piece 15, as shown in FIG. Next, 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 hitting tool such as a rubber hammer, but a press machine or the like may be used. In addition, when hitting with a rubber hammer or the like, it is preferable to put a backing plate on the substrate B and hit from above.

  Thereafter, by separating the substrate B from the jig 10, a heat radiating panel made of the substrate B with the aluminum sheet in which the flap 7 a is along the side wall surface of the groove 3 is obtained.

  If the material of the pushing piece 15 is too hard, the substrate B is deformed and the aluminum sheet 7 is damaged when the substrate B is pressed. On the contrary, if the material of the pushing piece 15 is too soft, a problem that the flap 7a does not follow the side wall surface of the groove 3 occurs. Therefore, it is preferable that the pushing piece 15 is made of a material having a 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 in accordance with the shape of the substrate B. The stopper 13 is preferably made of a rubber material so that deformation does not occur when the substrate B is pressed.

  Although the kind of said blade 14 is not specifically limited, For example, a straight blade, a sewing machine blade, a saw blade etc. are mentioned. Especially, since a saw blade is easy to bite into the aluminum sheet 7, and it is easy to cleave the aluminum sheet 7, it is preferable.

  In the above embodiment, the upper surface of the pushing piece 15 is horizontal, but 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 a mode other than the above.
