The shielding layer may undergo an oxidation reaction at a higher temperature, resulting in a decrease in shielding performance. Summary of the Utility Model

[0020] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides a cloth-based tape that can shield electromagnetic waves, including a surface layer 1. A cushion layer 3 is provided at the bottom of the surface layer 1, a heat-conducting layer 4 is provided at the bottom of the cushion layer 3, a shielding layer 7 is provided at the bottom of the heat-conducting layer 4, a bonding layer 8 is provided at the bottom of the shielding layer 7, a protective layer 12 is provided at the bottom of the bonding layer 8, an adhesive layer 2 is provided at the bottom of the protective layer 12. A plurality of second side grooves 9 are equidistantly opened at the top of the bonding layer 8. A heat-conducting strip 10 is provided on the inner surface of the second side groove 9. A plurality of heat sinks 11 are equidistantly provided on the outer surfaces on both sides of the heat-conducting strip 10. The thicknesses of the heat-conducting strip 10 and the heat sinks 11 are equal to the depth of the second side groove 9. The cross-sections of the heat-conducting strip 10 and the heat sinks 11 are smaller than the cross-section of the second side groove 9. The heat-conducting strip 10 and the heat sinks 11 are respectively in a fitting state with the shielding layer 7 and the inner bottom of the second side groove 9. The cross-sectional sizes of the surface layer 1 and the adhesive layer 2 are equal. The cross-sections of the cushion layer 3, the heat-conducting layer 4, the shielding layer 7, the bonding layer 8, and the protective layer 12 are all equal to the cross-sectional size of the surface layer 1.

[0023] The effect achieved by the entire Example 1 is that when the cloth-based tape is prepared and used, the adhesive layer 2 enables the tape to adhere to an object for use. Through the use of the shielding layer 7, the shielding layer 7 shields electromagnetic waves through its conductive properties. When electromagnetic waves encounter the shielding layer 7, their energy will be absorbed by the conductive material used in the shielding layer 7, thereby effectively preventing the propagation of electromagnetic waves. The heat generated by the adhered object will be conducted through the adhesive layer 2, and the heat of the adhesive layer 2 will be conducted through the protective layer 12, the bonding layer 8, the heat-conducting layer 4, the cushion layer 3, and the surface layer 1 to the air for heat dissipation. When the heat is conducted through the bonding layer 8, through the setting of the second-side groove 9 on the bonding surface of the bonding layer 8 and the shielding layer 7, a heat dissipation channel can be formed inside the second-side groove 9, and the air flow can pass through the second-side groove 9 to carry out the heat of the bonding layer 8 and the shielding layer 7 through the circulation of the air flow. Through the combined use of the heat-conducting strip 10 and the heat sink 11, the heat-conducting strip 10 with strong heat conductivity achieves the purpose of accelerating heat dissipation in the air flow channel. The use of multiple heat sinks 11 can enable the heat-conducting strip 10 to have a large contact area with the air, and increasing the heat dissipation area can significantly improve the heat transfer ability from the heat source to the surrounding environment, enabling the heat to spread to a larger surface area, thereby accelerating the dissipation of heat. The heat dissipation efficiency for the heat generated by the adhered object is relatively high, avoiding the shielding layer 7 from being invalidated due to high temperature after long-term contact with the object, which affects the shielding performance.

[0024] Example 2 is as Figures 1 - 4 shown. A plurality of first-side grooves 5 are equidistantly formed at the bottom of the heat-conducting layer 4. A heat-conducting pad 6 is arranged on the inner surface of the first-side groove 5. The cross-section of the heat-conducting pad 6 is smaller than the cross-section of the first-side groove 5. The heat-conducting pads 6 are respectively in a fitting state with the shielding layer 7 and the inner bottom of the first-side groove 5.

[0025] The effect achieved by the entire Example 2 is that through the combined use of the first-side groove 5 and the heat-conducting pad 6, after the shielding layer 7 is cooled and dissipated of heat through the heat-conducting strip 10 and the heat sink 11, its heat will continue to be conducted to the position of the heat-conducting pad 6. The heat-conducting pad 6 located inside the first-side groove 5 can play a role in ventilation and heat dissipation, further improving the heat dissipation efficiency for the shielding layer 7.

[0026] Working principle: When the cloth-based tape is prepared and used, the adhesive layer 2 enables the tape to adhere to an object for use. Through the use of the shielding layer 7, the shielding layer 7 shields electromagnetic waves through its electrical conductivity. When electromagnetic waves encounter the shielding layer 7, their energy will be absorbed by the conductive material used in the shielding layer 7, thus effectively preventing the propagation of electromagnetic waves. The heat generated by the adhered object will be conducted through the adhesive layer 2. The heat of the adhesive layer 2 will be conducted to the air for heat dissipation through the protective layer 12, the bonding layer 8, the heat-conducting layer 4, the cushion layer 3, and the surface layer 1. When the heat is conducted through the bonding layer 8, through the setting of the second-side groove 9 on the bonding surface of the bonding layer 8 and the shielding layer 7, a heat dissipation channel can be formed inside the second-side groove 9, and air flow can pass through the second-side groove 9, taking out the heat of the bonding layer 8 and the shielding layer 7 by the flow of the air flow. Through the combined use of the heat-conducting strip 10 and the heat sink 11, the heat-conducting strip 10 with strong heat conductivity achieves the purpose of accelerating heat dissipation in the air flow channel. The use of multiple heat sinks 11 can make the heat-conducting strip 10 have a large contact area with the air, and increasing the heat dissipation area can significantly improve the heat transfer ability from the heat source to the surrounding environment, enabling the heat to diffuse to a larger surface area, thereby accelerating the dissipation of heat. The heat dissipation efficiency for the heat generated by the adhered object is relatively high, avoiding the shielding layer 7 from failing due to high temperature after long-term adhesion to the object, which affects the shielding performance. Through the combined use of the first-side groove 5 and the heat-conducting pad 6, after the shielding layer 7 is cooled and dissipated by the heat-conducting strip 10 and the heat sink 11, its heat will continue to be conducted to the position of the heat-conducting pad 6. The heat-conducting pad 6 located inside the first-side groove 5 can play a role in ventilation and heat dissipation, further improving the heat dissipation efficiency of the shielding layer 7.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
