On the surface layer of the temperature-equalizing film, the effect of identifying and marking is achieved.

However, since the temperature equalizing sheet is often used in a high-temperature environment, it is often easy to cause melting and peeling of the ink after a period of use, so that the identification mark gradually degrades, and ultimately the identification effect cannot be effectively achieved.

The detailed description and technical content of the present invention will now under:

As shown in FIGS. 1 and 4, the present invention is a heat dissipation label with high contrast chromatic aberration to form an identification mark. The heat dissipation label 10 includes a thermally conductive substrate 20, a bright layer 30 and a contrast layer 40.

The thermally conductive substrate 20 includes a metal layer 21 and a thermally conductive layer 22. The metal layer 21 is made of a metal material with high thermal conductivity (such as copper). The thermally conductive layer 22 is formed of a graphite material with a better thermal conductivity (such as thin graphite), and the thermally conductive layer 22 is plated on the surface of the metal layer 21 by sputtering to cover the metal layer 21. It can make the surface of the thermally conductive layer 22 and the metal layer 21 bonded to have a better link, so that the thermally conductive substrate 20 can obtain a better thermal conduction effect.

The bright layer 30 includes a first insulating layer 31 and an identification layer 32. The first insulating layer 31 is composed of a material with insulating properties, such as PET (polyethylene terephthalate) material. The identification layer 32 is plated on the first insulating layer 31 by electroplating, and the identification layer 32 has a first color. The bright layer 30 is located on one surface of the thermally conductive substrate 20, that is to say the first insulating layer 31 is located on the thermally conductive layer 22, and the identification layer 32 passes through the first insulating layer 31 and the thermal conductivity The layers 22 are opposed to each other.

The contrast layer 40 includes a second insulating layer 41 and a shielding layer 42. The second insulating layer 41 is composed of a material with insulating properties, such as PET (polyethylene terephthalate) material, and the second insulating layer 41 is transparent. The shielding layer 42 is directly plated on the second insulating layer 41 by electroplating, and the shielding layer 42 has a second color. The color of the shielding layer 42 and the color of the identification layer 32 have high contrast. For example, if the first color of the identification layer 32 is a high-brightness color such as red, yellow, green, gold, or silver, and the second color of the shielding layer 42 The color is represented by a dark color (such as ink) or white color, so that the high contrast color difference is formed between the identification layer 32 and the shielding layer 42. The contrast layer 40 is coated on the bright layer 30, that is, the second insulating layer 41 is located on the identification layer 32, and the shielding layer 42 is connected to the identification layer through the second insulating layer 41 32 relative. In other words, the identification layer 32 will be sandwiched between the first insulating layer 31 and the second insulating layer 41, so as to ensure that the identification layer 32 will not be easily impacted by external force to the first insulation There is a peeling phenomenon between the layer 31 and the second insulating layer 41.

As shown in FIGS. 3 to 6, the shielding layer 42 can be further partially removed on the second insulating layer 41. The method of removing the shielding layer 42 is by laser engraving, which mainly uses laser The light hits the shielding layer 42 to remove the area where the shielding layer 42 is hit by the laser light, so that the area where the shielding layer 42 is partially removed forms an identification mark 43 on the second insulating layer 41 . The identification mark 43 formed by the laser engraving method has the effect of miniaturization. At present, the minimum line diameter of the laser engraving technology can reach 0.1mm, so that it can be applied not only to miniaturized products, but also to The identification mark 43 can be changed in various complicated shapes. The identification mark 43 can be used as LOGO, QR CODE, or product model.

When the identification mark 43 is formed on the shielding layer 42, since the identification layer 32 has the high contrast color difference between the shielding layer 42, the first color of the identification layer 32 can pass through the identification mark 43 is displayed on the shielding layer 42. Furthermore, since the identification layer 32 is exposed in the identification mark 43 through the second insulating layer 41, the identification layer 32 exposed in the identification mark 43 is protected by the second insulating layer 41, It can effectively prevent the identification layer 32 from peeling, while maintaining the integrity of the identification mark 43.

In addition, the heat dissipation label 10 of the present invention can further form a printed layer 50 on the contrast layer by printing on the area where the shielding layer 42 is not removed. The printed layer 50 can be used to print bar codes and other content. In this way, in addition to the identification mark 43 on the shielding layer 42, the printed layer 50 can also be used to present more information together, so that the product information that can be exposed on the heat dissipation label 10 is more complete.

When the heat dissipation label 10 is applied to SSD (Solid State Drive), CPU cooling module, motherboard, modem, LED cooling module, tablet computer, notebook computer or smart phone, it can pass the heat conduction The substrate 20 quickly guides the thermal energy generated during the operation of these products, so as to effectively achieve the effect of cooling, and at the same time, it can reveal the product information more completely through the identification mark 43 and can pass through the first insulating layer 31 The effect of double electromagnetic shielding with the second insulating layer 41 makes the applicability of the heat dissipation label 10 more extensive.

Finally, as shown in FIGS. 4 and 7, the heat dissipation label 10 can be further attached to a connecting layer 60 in advance. The connecting layer 60 can be made into a sheet type as shown in the figure, and can also be used as a tape and reel type In order to attach a plurality of the heat dissipation labels 10 to the connection layer 60 at the same time, so as to be able to be applied to the aforementioned products in the future. When the heat dissipation label 10 is pre-attached on the connection layer 60, a thermally conductive adhesive 61 is first used to attach to the other surface of the thermally conductive substrate 20 relative to the bright layer 30, and the thermally conductive back The adhesive 61 is a double-sided adhesive. Therefore, the thermally conductive adhesive 61 can be used to attach the heat dissipation label to the connection layer 60, so that the plurality of heat dissipation labels 10 can be attached to the connection layer 60 at intervals. In order to facilitate the subsequent installation work of the heat dissipation label 10.

In summary, the present invention has indeed met the requirements of the invention patent, so a patent application was filed in accordance with the law. However, the above is only a preferred embodiment of the present invention, and it cannot be used to limit the scope of patent application in this case. Anyone who is familiar with the skills of this case with the aid of other modifications or changes made in accordance with the spirit of the present invention should be covered by the following patent applications.
