3 is a cross-sectional view illustrating a process of preparing a heat transfer unit according to an embodiment of the present invention.

3, in the step of preparing the heat transfer part 200, the sanding surface 220 may be formed by sanding the surface of the second body 210 using a grinder or the like to roughen the surface of the second body 210 )Reference). The second body 210 may be made of a metal material, for example, an aluminum plate, to physically contact the heater and transmit heat generated from the heater to the hair contacting portion. One surface of the second body 210 may have a heater receiving structure protruding outward to receive the heater. The adhesive force between the second adhesive 230 and the second body 210 can be enhanced by applying the second adhesive to the sanding surface 220. [ Then, the second adhesive 230 is applied on the sanding surface 220 (see (c)).

Thereafter, the press can press-mold the hair contact portion 100, the insertion member 300, and the heat cut portion 200 at a predetermined temperature (160 to 180 ° C) and pressure to produce a heat generating plate (see FIG. The insertion member 300 may be formed as an intermediate layer 310 by being adhered to the first adhesive layer 131 of the hair contact portion and the second adhesive layer 231 of the heat transfer portion by high temperature during compression molding by press. The insertion member 300 may be a silicone rubber having high heat resistance, non-toxicity, heat resistance, thermal conductivity, and insulation. The silicone rubber may have a thickness of 0.2 to 0.3 mm. The silicone rubber 300 injected between the hair contact portion 100 and the heat transfer portion 200 may be smaller than the area of the heat transfer portion. The silicone rubber 300, which is smaller than the area of the heat transfer portion, may be formed as the intermediate layer 310 by being pressed sideways while being pressed by heat and pressure when formed by the press. The heat generating plate 1000 is adhered and hardened by being pressed to the upper and lower surfaces of the inserting member (for example, silicone rubber) at high temperatures while the first adhesive and the second adhesive applied at the time of compression molding at a high temperature by the press are cured, The adhesive layer 131, the intermediate layer 310 and the second adhesive layer 231 can be formed. Thereafter, the heating plate 1000 is taken out from the press, and the surface is naturally dried and then the surface is mapped.

Therefore, the heat generating plate 1000 of the present invention is formed not by attaching the Teflon sheet, which is the first body, to the aluminum metal plate as the second body through one adhesive, but also to the Teflon sheet through the silicone rubber, And the second adhesive having strong adhesion to the metal sheet can be used, so that the Teflon sheet can be firmly attached to the metal sheet. On the other hand, even when the first adhesive and the second adhesive are used as the same adhesive, the Teflon sheet can be more firmly attached to the metal plate due to the presence of the intermediate layer formed by pressurizing the silicone rubber inserted at a high temperature. Therefore, even if the iron plate having the heat generating plate of the present invention is used for a long time, the durability of the iron plate can be improved because the Teflon sheet does not fall off the metal plate.

The heat generating plate 1000 manufactured by the method of manufacturing the heat sink heating plate described above includes a metal plate 210 for contacting the heater to transmit heat, a second adhesive layer 231 formed on one surface of the metal plate, A middle layer 310, a first adhesive layer 131 formed on the intermediate layer, and a Teflon sheet 110 bonded to the first adhesive layer. The intermediate layer may be formed by heat and pressure of the silicone rubber. The heat generating plate 1000 may have an intermediate layer 310 formed between the hair contacting portion 100 and the heat transfer portion 200. The intermediate layer 310 can be formed by heat and pressure of the insertion member by the press. The first body 110 and the intermediate layer 310 of the hair contact portion are bonded by the first adhesive layer 131 and the second body 210 of the heat transfer portion and the intermediate layer 310 are bonded by the second adhesive layer 231 . The first adhesive layer 131 may be an adhesive capable of bonding a fluororesin (for example, a Teflon sheet) and a silicone material (for example, silicone rubber), and the second adhesive layer 231 may be a silicone material Rubber) and a metal material.
