[0001] The utility model relates to the technical field of thermal conductive pads, in particular to a silicone oil-free thermal conductive pad. Background Art

[0002] Silicone-free thermal pads are a non-silicone thermally conductive material based on a special resin. They are made by adding metal oxides and special additives and undergoing a specialized process. Their key features include the absence of siloxane volatilization and silicone oil precipitation, thus avoiding the potential circuit failure and contamination associated with traditional silicone-based materials. Consequently, silicone-free thermal pads, also known as oil-free and pollution-free thermal pads, are particularly suitable for silicon-sensitive applications.

[0003] Electronic devices generate a lot of heat during operation. In order to dissipate heat from the components inside the electronic devices, silicone-free thermal pads need to be attached to the surfaces of the components. However, existing silicone-free thermal pads are prone to curling after being used for a period of time, which affects the heat dissipation effect of the silicone-free thermal pads and is easy to fall off. Therefore, it is necessary to propose a silicone-free thermal pad to solve the above problem. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figures 1-4The shown type of silicone oil-free thermal conductive gasket includes a gasket body 1, and a thermal conductive adhesive layer 4 and a release film 5 are sequentially arranged at the bottom of the gasket body 1. An easy-tear strip 6 is fixedly arranged at the end of the release film 5. When using the gasket body 1, the easy-tear strip 6 is held in hand to tear off the release film 5, so that the gasket body 1 is attached to the heating element of the electronic device through the thermal conductive adhesive layer 4 to dissipate heat from the heating element. However, after being used for a period of time, the gasket body 1 is prone to curling, which affects the heat dissipation effect of the gasket body 1 and makes the gasket body 1 easy to fall off. Therefore, the utility model provides a slot 2 on the outer wall of the gasket body 1, which is located in the internal structural layer of the gasket body 1. The slot 2 is a "U"-shaped structure, and the slot 2 passes through the side wall of the gasket body 1. The inside of the slot 2 is provided with a heat dissipation copper plate 3 fixedly connected to the gasket body 1 through thermal conductive adhesive.

[0026] Specifically, by inserting the heat dissipation copper plate 3 into the middle part of the edge of the gasket body 1, the edge of the gasket body 1 is reduced to reduce the curling of the gasket body 1 after a period of use under the action of the gravity of the heat dissipation copper plate 3, thereby ensuring the heat dissipation effect of the gasket body 1, and solving the problem that the heating elements of the electronic device are dissipated by attaching the gasket body 1, but the gasket body 1 is prone to curling after a period of use, affecting the heat dissipation effect of the gasket body 1.

[0027] In order to allow the heat dissipation copper plate 3 to assist the gasket body 1 in dissipating heat, the four ends of the heat dissipation copper plate 3 are extended out of the slot 2 and protrude from the side of the gasket body 1, thereby increasing the contact area between the heat dissipation copper plate 3 and the air, allowing the heat on the heat dissipation copper plate 3 to be dissipated into the air faster, assisting the heat dissipation of the gasket body 1 and improving the heat dissipation effect of the gasket body 1.

[0028] In addition, in order to further increase the contact area between the heat dissipating copper plate 3 and the air, an auxiliary heat dissipating component is provided on the heat dissipating copper plate 3, and the auxiliary heat dissipating component includes heat dissipating fins 7. There are a plurality of heat dissipating fins 7, and the heat dissipating fins 7 are evenly arranged and distributed on the four edges of the heat dissipating copper plate 3. Thus, by providing a plurality of heat dissipating fins 7, the contact area between the heat dissipating copper plate 3 and the air is greatly increased, and the heat on the gasket body 1 is dissipated faster.

[0029] Taking into account that the adhesion between the thermal conductive adhesive layer 4 and the heating element decreases after the gasket body 1 has been used for a period of time, in order to avoid the problem that the gasket body 1 is easy to fall off, a fixing component is also provided on the heat dissipation copper plate 3, and the fixing component includes four circular copper plates 12 respectively fixed at the four corners of the heat dissipation copper plate 3, and the interior of the circular copper plate 12 is fixedly provided with a threaded hole 13, and the inner circle of the threaded hole 13 is threadedly connected with a threaded rod 14, and the top of the threaded rod 14 is fixedly provided with a handle 15, and the bottom of the threaded rod 14 is fixedly provided with a suction cup 17. Turning the handle 15 drives the threaded rod 14 to move downward in the threaded hole 13, allowing the suction cup 17 to be adsorbed on the mounting plate of the heating element, thereby improving the attachment stability of the gasket body 1 and making the gasket body 1 and the heating element in close contact, which can more effectively take away the heat from the heating element.

[0030] In addition, the height of the suction cup 17 can be adjusted by lifting and lowering the threaded rod 14 to accommodate heating elements of different heights.

[0031] Furthermore, a plurality of anti-slip strips 16 distributed in a ring shape are fixedly provided on the outer ring of the handle 15. The installation of the anti-slip strips 16 facilitates the rotation of the handle 15 without slipping.

[0032] Furthermore, an exhaust pipe 18 and an air outlet pipe 21 are fixedly provided on the side of the suction cup 17, a one-way valve is provided inside the exhaust pipe 18, and a piston 20 is provided inside the air outlet pipe 21. The piston 20 and the air outlet pipe 21 are interference fit, and the piston 20 is connected to the suction cup 17 through a connecting rope 19. When the suction cup 17 is pressed against the mounting plate of the heating element, the air inside the suction cup 17 flows out from the exhaust pipe 18 through the one-way valve, so that the suction cup 17 is adsorbed on the mounting plate. When the gasket body 1 needs to be removed, the piston 20 is pulled out from the inside of the air outlet pipe 21 through the connecting rope 19, the pressure inside the suction cup 17 is replenished, and the adsorption of the suction cup 17 on the mounting plate is cancelled, so that the gasket body 1 can be directly taken from the heating element, which is convenient for the fixed installation and disassembly of the gasket body 1 without damaging the mounting plate.

[0033] In order to further improve the close contact between the gasket body 1 and the heating element, a leveling component is also provided on the heat dissipation copper plate 3, and the leveling component includes a first side plate 8 and a second side plate 10. The first side plate 8 and the second side plate 10 are both fixedly arranged on the heat dissipation copper plate 3, and the first side plate 8 and the second side plate 10 are respectively located on the longitudinal center line and the transverse center line of the heat dissipation copper plate 3. The first side plate 8 and the second side plate 10 are symmetrically distributed about the center line of the heat dissipation copper plate 3. A first horizontal plate 9 is fixedly arranged between the tops of the two first side plates 8, and a second horizontal plate 11 is fixedly arranged between the tops of the two second side plates 10. The first side plate 8, the first horizontal plate 9, the second side plate 10 and the second horizontal plate 11 are all fitted together with the gasket body 1. By installing the first side plate 8, the first horizontal plate 9, the second side plate 10 and the second horizontal plate 11, the gasket body 1 is leveled so that the gasket body 1 is in full close contact with the heating element, avoiding the problem of low heat dissipation efficiency in this part due to local protrusions.

[0034] Furthermore, the first side plate 8 , the first transverse plate 9 , the second side plate 10 and the second transverse plate 11 are all made of copper, so that the gasket body 1 can be leveled while assisting in heat dissipation of the gasket body 1 .
