[0002] A thermal pad is a pad made of thermally conductive material, used as an auxiliary material to provide heat conduction and heat dissipation between electronic equipment and radiators.
[0003] At present, thermal conductive gaskets are installed between electronic devices and radiators. However, after the equipment has been running for a certain period of time, as the temperature rises, the gasket material will soften and creep, resulting in gasket stress relaxation, causing the sealing performance to deteriorate and unable to fit closely between the equipment and the radiator. Therefore, a composite thermal conductive gasket is urgently needed. Utility Model Content

[0005] Preferably, a first adhesive layer is provided between the support plate and the gasket body, and the thickness of the first adhesive layer is set to 0.2-0.5 cm.
[0006] Preferably, a fitting gasket for fitting with an electronic device or a radiator is provided on the outer side surface of the support plate, and the fitting gasket and the gasket body are both made of silicone material.
[0007] Preferably, a second adhesive layer is provided between the outer side surface of the support plate and the fitting gasket, and the curvature of the second adhesive layer is set to 0.2-0.5 cm.
[0008] Preferably, a heat dissipation hole connected to the through slot is provided on the fitting gasket, and a heat dissipation channel is formed between the corresponding upper and lower heat dissipation holes and the through slot.
[0009] Preferably, the support plate is supported by a ceramic sheet or a graphite sheet, and the thickness is set to 0.5-1.5 cm.
[0010] By means of the above technical solution, the utility model provides a composite thermally conductive pad, which has at least the following beneficial effects:
[0011] 1. This composite thermally conductive gasket has hard support plates attached to the upper and lower surfaces of the gasket body, and a number of return springs are arranged between the two support plates, which can prevent the gasket body from loosening and reducing the sealing between the device and the radiator after the gasket body is softened at high temperature.
[0012] 2. The composite thermally conductive gasket is also provided with heat dissipation holes on the bonding gasket that are connected to the internal grooves of the gasket body to form a heat dissipation channel, which can accelerate heat transfer and thus improve the heat dissipation effect.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Combination Figure 1-Figure 3 As shown, the utility model provides: a composite thermally conductive gasket, comprising a gasket body 1, the upper and lower surfaces of the gasket body 1 are fixed with support plates 2 for providing rigid support, a first adhesive layer 5 is laid between the support plate 2 and the gasket body 1, the thickness of the first adhesive layer 5 is 0.2-0.5cm, the support plate 2 is supported by a ceramic sheet or a graphite sheet, and the thickness is 0.5-1.5cm, a plurality of through grooves 3 are opened between the gasket body 1 and the two support plates 2, and a reset spring 4 for flexibly supporting the gasket body 1 is installed in the through groove 3, and the reset spring 4 provides an outward thrust to the upper and lower support plates 2, and can provide support force when the gasket body 1 is relaxed at high temperature, so as to avoid the problem of reduced sealing between the device and the radiator due to relaxation;
[0021] Furthermore, a fitting gasket 6 for fitting with an electronic device or a radiator is installed on the outer side of the support plate 2. The fitting gasket 6 and the gasket body 1 are both made of silicone material, which has good toughness and thermal conductivity. A second adhesive layer 7 is laid between the outer side of the support plate 2 and the fitting gasket 6. The curvature of the second adhesive layer 7 is 0.2-0.5 cm.
[0022] Furthermore, a heat dissipation hole 8 connected to the through groove 3 is opened on the fitting gasket 6, and the corresponding upper and lower heat dissipation holes 8 and the through groove 3 form a heat dissipation channel, which can transfer the heat generated by the equipment to the outside through the air and accelerate the volatilization of heat.
[0023] In the present solution, a support plate 2 is respectively fixed to the upper and lower surfaces of the pad body through a first adhesive layer 5, and a plurality of reset springs 4 are connected between the upper and lower support plates 2. When the gasket body 1 is relaxed and softened by an external force, these reset springs 4 can provide support force to the gasket body 1 to avoid softening and relaxation of the gasket body 1, always maintain the sealing between the equipment and the heat dissipation, and have a heat conduction effect. In addition, a heat dissipation hole 8 is provided on the external fitting gasket 6, which is usually matched with the gasket body 1 for installing the reset spring 4 to directly bring out the external hot air and improve the heat dissipation efficiency.
