Description

Technical Field

[0001] This utility model relates to the field of thermally conductive silicone pad technology, specifically to a combined thermally conductive silicone pad with an embedded thermally conductive structure. Background Technology

[0002] Thermal conductive silicone pads are a type of thermally conductive medium material synthesized through a special process using silicone as the base material and adding various auxiliary materials such as metal oxides. In the industry, they are also known as thermal conductive silicone pads, thermal conductive silicone sheets, soft thermal conductive pads, thermal conductive silicone gaskets, etc. They are specially designed and manufactured to transfer heat through gaps, filling gaps and opening up thermal channels between heat-generating and heat-dissipating parts, effectively improving heat transfer efficiency.

[0003] Thermally conductive silicone pads with embedded thermal conductive structures, especially those with embedded pipes, carry away heat through the flow of coolant. However, the embedded pipes themselves have a small diameter and are relatively soft. When subjected to significant external force, the embedded pipes can deform, affecting the flow of coolant or even causing damage, thus affecting the performance of the thermally conductive silicone pad. Utility Model Content

[0004] The purpose of this invention is to address the problem that, in the case of a thermally conductive silicone pad with an embedded tube, the heat is carried away by the flow of coolant, but the embedded tube itself has a small diameter and is relatively soft. When subjected to a large external force, the embedded tube will deform, affecting the flow of coolant or even breaking, thus affecting the performance of the thermally conductive silicone pad. The invention provides a combined thermally conductive silicone pad with an embedded thermally conductive structure.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A combined thermally conductive silicone sheet with an embedded thermally conductive structure includes a thermally conductive silicone sheet, a groove is formed on the top surface of the thermally conductive silicone sheet, a thermally conductive tube is disposed in the groove, bottom plates are provided on both sides of the bottom of the thermally conductive silicone sheet, an H-shaped release paper is adhered and fixed to the lower part of the thermally conductive silicone sheet, and an upper release unit is adhered and fixed to the top surface of the thermally conductive silicone sheet.

[0007] As a further embodiment of this utility model: the bottom sheet includes a metal sheet bonded to the bottom of the thermally conductive silicone sheet, and a lower release paper is fixedly connected to the bottom end of the metal sheet.

[0008] As a further aspect of this utility model: the width of the metal sheet is smaller than the width of the thermally conductive silicone sheet, and the length of the metal sheet is less than half the length of the thermally conductive silicone sheet.

[0009] As a further embodiment of this utility model: the upper release unit includes an upper release paper that is adhered to the top surface of the thermally conductive silicone sheet.

[0010] As a further embodiment of this utility model: a silicone grease pack is provided on the top surface of the first upper release paper, adhesive is applied to the outer periphery of the silicone grease pack on the first upper release paper, and a second upper release paper is adhered and fixed to the upper part of the first upper release paper.

[0011] As a further embodiment of this utility model: the top surface of the silicone grease pack is equidistantly engraved with punctuation marks along the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting a bottom separator at the bottom of the thermally conductive silicone pad, a metal sheet is bonded to the bottom of the thermally conductive silicone pad. A lower release paper is fixedly connected to the bottom end of the metal sheet. The width of the metal sheet is set to be smaller than the width of the thermally conductive silicone pad, and the length of the metal sheet is set to be less than half the length of the thermally conductive silicone pad. In this way, the thermally conductive silicone pad is rigidly supported by the lower release paper. After being transferred to the designated position, the adhesiveness of the bottom edge of the thermally conductive silicone pad is used for pre-bonding. Then, the lower release paper is pulled to separate the metal sheet from the thermally conductive silicone pad, and then the metal sheet is bonded from the middle. This achieves effective bonding at the bottom, which can reduce the impact of deformation during the bonding process on the heat pipe, thereby effectively protecting the heat pipe.

[0014] 2. A silicone grease pack is placed on the top surface of the upper release paper one. Adhesive is applied to the outer periphery of the silicone grease pack on the upper release paper one. An upper release paper two is adhered and fixed to the upper part of the upper release paper one. By setting the silicone grease pack to be filled with silicone grease, the upper release paper two is peeled off, the silicone grease pack is punctured with a sharp needle, and then the upper release paper two is re-adhered and pressed, thereby filling the tube groove with silicone grease, reducing the gap between the heat pipe and the tube groove, and ensuring the thermal conductivity of the thermally conductive silicone pad.

Detailed Implementation

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] Please see Figure 1-4 As shown, in this embodiment, a combined thermally conductive silicone sheet with an embedded thermally conductive structure includes a thermally conductive silicone sheet 300. A groove 310 is formed on the top surface of the thermally conductive silicone sheet 300, and a thermally conductive pipe 400 is disposed in the groove 310. Bottom plates 200 are provided on both sides of the bottom of the thermally conductive silicone sheet 300. An H-shaped release paper 100 is adhered and fixed to the lower part of the thermally conductive silicone sheet 300, and an upper release unit 500 is adhered and fixed to the top surface of the thermally conductive silicone sheet 300. By providing bottom plates 200 at the bottom of the thermally conductive silicone sheet 300, the rigidity of the bottom plates 200 is used for support. When the thermally conductive silicone sheet 300 is bonded to the heat dissipation part, the deformation of the thermally conductive silicone sheet 300 can be effectively reduced, thereby protecting the internal thermally conductive pipe 400.

[0024] The bottom sheet 200 includes a metal sheet 210 bonded to the bottom of the thermally conductive silicone sheet 300. A lower release paper 220 is fixedly connected to the bottom end of the metal sheet 210. The width of the metal sheet 210 is smaller than the width of the thermally conductive silicone sheet 300, and the length of the metal sheet 210 is less than half the length of the thermally conductive silicone sheet 300. In this way, the lower release paper 220 provides rigid support for the thermally conductive silicone sheet 300. After being transferred to a designated position, the adhesiveness of the bottom edge of the thermally conductive silicone sheet 300 is used for pre-bonding. Then, the lower release paper 220 is pulled to separate the metal sheet 210 from the thermally conductive silicone sheet 300, and then bonding is performed from the middle, thereby achieving effective bonding at the bottom.

[0025] Please see Figure 1 , 2 As shown in Figure 5, in this embodiment, the upper release unit 500 includes an upper release paper 510 that is adhered to the top surface of the thermally conductive silicone sheet 300, and the upper release paper 510 protects the top adhesive layer.

[0026] A silicone grease pack 520 is provided on the top surface of the upper release paper 510. The upper release paper 510 is coated with adhesive around the silicone grease pack 520. An upper release paper 530 is attached and fixed to the upper part of the upper release paper 510. By filling the silicone grease pack 520 with silicone grease, the upper release paper 530 is peeled off, the silicone grease pack 520 is punctured with a needle, and then the upper release paper 530 is re-attached and pressed to fill the silicone grease into the tube groove 310, thereby reducing the gap between the heat pipe 400 and the tube groove 310. Finally, the upper release paper 510 is peeled off and the heat sink is placed on top of it.

[0027] The top surface of the silicone grease pack 520 is equidistantly marked with dots along the groove 310, so that the needle can puncture the dots to release the silicone grease in a directional manner.
