Description

Technical Field

[0001] The utility model relates to the technical field of silica gel sheets, and specifically relates to a heat-conducting silica gel sheet with tensile resistance. Background Technique

[0002] The heat-conducting silica gel sheet is a kind of silica gel made by mixing organic silica gel as the main body with fillers, heat-conducting materials, adhesive glues and other polymer materials, and has good heat-conducting, bonding and electrical insulation properties. It is mainly applied to the transfer interface between electronic devices and heat sinks or product shells, playing the role of filling voids, opening up the heat channel between the heat-generating part and the heat-dissipating part, and improving the heat transfer efficiency.

[0003] In the process of using the existing technology, although there are many benefits, there are still the following problems. It lacks a tensile structure for the heat-conducting sheet, resulting in the inconvenience of the heat-conducting sheet to adapt to different-sized usage positions and affecting the adaptability of the heat-conducting sheet. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat-conducting silica gel sheet with tensile resistance to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heat-conducting silica gel sheet with tensile resistance, including a first heat-conducting sheet, a storage groove, through holes and a second heat-conducting sheet. Through holes are arranged on the outer wall of the first heat-conducting sheet in a rectangular array distribution. A storage groove is arranged on one side of the inner wall of the through hole. A second heat-conducting sheet is arranged inside the storage groove. A third heat-conducting sheet is arranged on the outer wall of one end of the second heat-conducting sheet passing through the storage groove. Elastic sheets are fixedly attached to the outer wall of the first heat-conducting sheet in a rectangular array distribution.

[0006] When using the heat-conducting silica gel sheet with tensile resistance in this technical solution, the staff manually pulls the third heat-conducting sheet, and the third heat-conducting sheet drives the second heat-conducting sheet to move inside the storage groove, so as to unfold the third heat-conducting sheet.

[0007] Preferably, through holes are arranged in a rectangular array distribution inside the first heat-conducting sheet. The through holes adopt a through design and are connected with ventilation holes. The gas inside the storage groove is connected with the outside air through the through holes and the ventilation holes, so as to be able to discharge or enter the air inside the storage groove. And the through holes can give the first heat-conducting sheet a deformation space, ensure the deformation ability of the first heat-conducting sheet, and improve the tensile performance of the first heat-conducting sheet.

[0008] Preferably, anti-slip strips are fixedly attached to the outer walls of the upper and lower ends of the first heat-conducting sheet. The length of the anti-slip strips is adapted to the size of the first heat-conducting sheet. The anti-slip strips are designed in a rectangular shape. The anti-slip strips improve the friction between the first heat-conducting sheet and the connected device and improve the stability between the first heat-conducting sheet and the connected device.

[0009] Preferably, both the inner wall of the storage groove and the outer wall of the second heat conducting sheet are designed in a rectangular shape, and the storage groove is communicated with the inside of the through hole through the ventilation hole. The gas inside the storage groove can be discharged through the ventilation hole and the through hole, ensuring that the gas pressure inside the storage groove is constant, which is convenient for the staff to extract or reset the second heat conducting sheet.

[0010] Preferably, the third heat conducting sheet is located outside the first heat conducting sheet, and the upper and lower end faces of the third heat conducting sheet and the first heat conducting sheet are in a horizontal state. Both outer walls of the third heat conducting sheet are designed in an inclined shape. The third heat conducting sheet can transfer heat to the first heat conducting sheet through the second heat conducting sheet, ensuring the overall heat exchange performance of the plate and increasing the overall size of the plate.

[0011] Preferably, a dust-proof film is provided on the outer wall of the end of the third heat conducting sheet away from the second heat conducting sheet, and the dust-proof film is designed in a rectangular shape. The dust-proof film shields and protects the third heat conducting sheet, preventing external dust from contaminating the third heat conducting sheet.

[0012] Preferably, the elastic sheet corresponds to the position of the storage groove, and the outer wall of the elastic sheet is designed in a folded shape. The inner wall size of the elastic sheet is larger than the inner wall size of the storage groove. The elastic sheet can shield between the third heat conducting sheet and the first heat conducting sheet, thereby shielding and protecting the storage groove and the second heat conducting sheet. Moreover, the elastic performance of the elastic sheet can assist the third heat conducting sheet to reset.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the second heat conducting sheet, the storage groove and the elastic sheet, the present utility model achieves the effect of improving the adaptability of the heat conducting sheet. When the staff manually pulls the third heat conducting sheet, the third heat conducting sheet drives the second heat conducting sheet to move inside the storage groove, so that the third heat conducting sheet unfolds, which can increase the overall size of the plate, ensure that the plate can adapt to different sizes of use positions, and improve the adaptability of the plate.

Elastic sheets 13 distributed in a rectangular array are fixedly attached to the outer wall of the first heat-conducting sheet 1.

[0022] Through holes 12 distributed in a rectangular array are arranged inside the first heat-conducting sheet 1. The through holes 12 adopt a through design, and the through holes 12 are communicated with the ventilation holes 21. The gas inside the storage groove 2 is communicated with the outside air through the through holes 12 and the ventilation holes 21, so that the air inside the storage groove 2 can be discharged or entered. Moreover, the through holes 12 can give the first heat-conducting sheet 1 a deformation space, ensure the deformation ability of the first heat-conducting sheet 1, and improve the tensile performance of the first heat-conducting sheet 1.

[0023] Anti-slip strips 11 are fixedly attached to the outer walls of the upper and lower ends of the first heat-conducting sheet 1. The length of the anti-slip strips 11 is adapted to the size of the first heat-conducting sheet 1. The anti-slip strips 11 adopt a rectangular shape design. The anti-slip strips 11 improve the friction between the first heat-conducting sheet 1 and the connected device, and improve the stability between the first heat-conducting sheet 1 and the connected device.

[0024] Embodiment 2: A stretch-resistant heat-conducting silica gel sheet, including a first heat-conducting sheet 1, a storage groove 2, a through hole 12, and a second heat-conducting sheet 22. The outer wall of the first heat-conducting sheet 1 is provided with through holes 12 distributed in a rectangular array. One side of the inner wall of the through hole 12 is provided with a storage groove 2. A second heat-conducting sheet 22 is arranged inside the storage groove 2. A third heat-conducting sheet 23 is arranged on the outer wall of one end of the second heat-conducting sheet 22 penetrating through the storage groove 2. Elastic sheets 13 distributed in a rectangular array are fixedly attached to the outer wall of the first heat-conducting sheet 1.

[0025] The first heat conducting sheet 1 is provided with through holes 12 distributed in a rectangular array, the through holes 12 are of a through-type design, and the through holes 12 are connected with the vent holes 21. The gas inside the storage slot 2 is connected with the outside air through the through holes 12 and the vent holes 21, so that the air inside the storage slot 2 can be discharged or enter, and the through holes 12 can provide the first heat conducting sheet 1 with a deformation space, thereby ensuring the deformation capacity of the first heat conducting sheet 1 and improving the tensile strength of the first heat conducting sheet 1.

[0026] The outer walls of the upper and lower ends of the first heat conducting sheet 1 are fitted with anti-slip strips 11, the length of which matches the size of the first heat conducting sheet 1, and the anti-slip strips 11 are designed in a rectangular shape. The anti-slip strips 11 increase the friction between the first heat conducting sheet 1 and the connected device, and improve the stability between the first heat conducting sheet 1 and the connected device.

[0027] The inner wall of the storage slot 2 and the outer wall of the second heat conducting sheet 22 are both designed in a rectangular shape, and the storage slot 2 is connected to the inside of the through hole 12 through the vent hole 21. The gas inside the storage slot 2 can be discharged through the vent hole 21 and the through hole 12, ensuring that the gas pressure inside the storage slot 2 is constant, making it convenient for the staff to extract or reset the second heat conducting sheet 22.

[0028] The third heat conducting sheet 23 is located outside the first heat conducting sheet 1, and the upper and lower end surfaces of the third heat conducting sheet 23 and the first heat conducting sheet 1 are in a horizontal state, and the outer walls on both sides of the third heat conducting sheet 23 are designed in an inclined shape. The third heat conducting sheet 23 can transfer heat with the first heat conducting sheet 1 through the second heat conducting sheet 22, thereby ensuring the heat exchange performance of the entire plate and increasing the overall size of the plate.

[0029] The outer wall of the third heat conducting sheet 23 facing away from the second heat conducting sheet 22 is provided with a dustproof film 24, which is designed in a rectangular shape.

[0030] The elastic sheet 13 corresponds to the storage slot 2, and the outer wall of the elastic sheet 13 is designed in a folded shape, and the inner wall size of the elastic sheet 13 is larger than the inner wall size of the storage slot 2. The elastic sheet 13 can block the third heat conductive sheet 23 and the first heat conductive sheet 1, thereby shielding and protecting the storage slot 2 and the second heat conductive sheet 22, and the elastic performance of the elastic sheet 13 can assist the third heat conductive sheet 23 to reset. When the staff manually pulls the third heat conductive sheet 23, the third heat conductive sheet 23 drives the second heat conductive sheet 22 to move inside the storage slot 2, so that the third heat conductive sheet 23 is unfolded, which can increase the overall size of the plate, ensure that the plate can adapt to the use positions of different sizes, and improve the adaptability of the plate.
