Description

Technical Field

[0001] This utility model relates to the field of thermal conductive pad technology, specifically a high-temperature resistant thermal conductive pad with protective function. Background Technology

[0002] Thermal pads are high-performance gap-filling thermally conductive materials, mainly used for heat conduction between heat-generating components and heat sinks or metal bases in electronic devices. Thermal pads are highly compressible, soft, and elastic, capable of covering uneven surfaces, effectively eliminating air gaps, and improving heat conduction efficiency. To further enhance the thermal conductivity of thermal pads, thermal pads with internal heat-conducting fins have been developed, which can accelerate the conduction and transfer of heat from electrical appliances.

[0003] However, since different electrical appliances have different distributions of charged parts inside, the amount of heat transferred downwards in different areas inside the appliance is also different. Existing thermal pads with thermal conductive structures usually cannot change the position of the thermal fins, which makes it impossible to adjust the density of the thermal fins, thus easily leading to poor heat conduction. On the other hand, covering the thermal pad with thermal fins completely results in high usage costs.

[0004] To address these issues, we designed a protective high-temperature resistant thermally conductive pad. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant thermally conductive pad with protective function to solve the problems mentioned in the background art.

[0014] Further, the top and bottom of the reinforcing member are provided with mounting grooves, and the heat-conducting gasket body is fixedly installed in the mounting grooves.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0023] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a kind of high-temperature-resistant heat-conducting gasket with protection, including two heat-conducting gasket main bodies 1 and reinforcing member 2 installed between two heat-conducting gasket main bodies 1, comprising,

[0024] Cavity 3 is opened in reinforcing member 2 along transverse direction;

[0025] Fixed box 4 is set with the same direction as cavity 3, and is fixedly installed in the top wall of cavity 3;

[0026] Heat-conducting fin 5, the number is multiple, is slidably arranged in cavity 3, and is connected with fixed box 4, for adjusting the position and density of multiple heat-conducting fins 5.

[0027] Specific implementation, when using, the heat-conducting gasket can be installed in the gap between electric appliance and radiator, the heat transferred by electric appliance can be transferred to radiator for heat dissipation through heat-conducting gasket main body 1, reinforcing member 2, fixed box 4 and heat-conducting fin 5, and the arrangement of some parts inside electric appliance can be different, at this time, in order to ensure that the gasket can efficiently conduct heat, at this time, heat-conducting fin 5 can be pulled to slide in cavity 3, not only the position of heat-conducting fin 5 in cavity 3 can be changed, but also multiple heat-conducting fins 5 can be combined to improve the density of heat absorption and heat conduction, so as to improve the effect of heat conduction.

[0028] It should be noted that, in order to improve the high-temperature resistance of heat-conducting gasket main body 1, the material of heat-conducting gasket main body 1 can be set as fluororubber, since fluororubber can be used for long-term at 250 DEG C and short-term at 300 DEG C, and has excellent aging resistance and weather resistance, so as to improve the high-temperature resistance of the heat-conducting gasket, in addition, the high-temperature resistance can also protect the heat-conducting gasket from side, which helps to prolong the service life of the heat-conducting gasket.

[0029] Please refer to Figures 1-4 It is shown that the top of heat-conducting fin 5 is provided with sliding groove 6, positioning strip 7 is slidably inserted in sliding groove 6, the bottom of fixed box 4 is provided with multiple clamping grooves 9, the top of positioning strip 7 is slidably inserted in clamping groove 9, and support spring 8 is fixedly installed between the bottom wall in sliding groove 6 and positioning strip 7.

[0030] In actual implementation, on the basis of the above implementation, before adjusting the position of the heat-conducting fin 5, pulling down the positioning strip 7 can make the positioning strip 7 compress the supporting spring 8 to slide in the sliding groove 6, so that the heat-conducting fin 5 can normally slide, and after adjusting the position of the heat-conducting fin 5, releasing the positioning strip 7 can make the supporting spring 8 push the positioning strip 7 out of the sliding groove 6 and into the clamping groove 9 due to the elastic force of the supporting spring 8, so as to ensure the stability of the heat-conducting fin 5 and avoid the problem of deviation of the heat-conducting fin 5 due to the vibration transmitted from the outside. By arranging the permanent magnet 11, the positioning strip 7 can be adsorbed when contacting the permanent magnet 11, so that the positioning strip 7 can be simply positioned, and the personnel can conveniently slide the heat-conducting fin 5.

[0031] Referring to Figures 1-4 The front side of the positioning strip 7 is fixedly installed with a pulling block 10. Pulling the pulling block 10 can make the pulling block 10 drive the positioning strip 7 to move, so that the personnel can save labor when pulling the positioning strip 7.

[0032] Referring to Figures 1-4 The outer surface of the pulling block 10 is provided with anti-skid lines. The anti-skid lines can increase the friction between the hands of the personnel and the pulling block 10, so as to help solve the problem of slipping when the personnel pulls the pulling block 10.

[0033] Referring to Figures 1-4 The inner bottom wall of the sliding groove 6 is fixedly installed with a permanent magnet 11, the material of the positioning strip 7 is iron, and the positioning strip 7 is magnetically connected with the permanent magnet 11 in cooperation. By arranging the permanent magnet 11, the positioning strip 7 can be adsorbed when contacting the permanent magnet 11, so that the positioning strip 7 can be simply positioned, and the personnel can conveniently slide the heat-conducting fin 5.

[0034] It should be noted that the adsorption of the positioning strip 7 and the permanent magnet 11 needs the positioning strip 7 to descend to half of the stroke, so as not to worry that the positioning strip 7 is adsorbed by the permanent magnet 11 due to the vibration transmitted from the electric appliance.

[0035] The top and the bottom of the reinforcing part 2 are both provided with an installation groove 12, and the heat-conducting gasket main body 1 is fixedly installed in the installation groove 12. The installation groove 12 can increase the stability between the reinforcing part 2 and the heat-conducting gasket main body 1.

[0036] Working principle: when in use, the heat-conducting gasket can be installed in the gap between the electric appliance and the heat sink, the heat transmitted from the electric appliance can be transmitted to the heat sink through the heat-conducting gasket main body 1, the reinforcing part 2, the fixing box 4 and the heat-conducting fin 5 to be dissipated, and the arrangement of the parts inside some electric appliances can be different, at this time, in order to ensure that the gasket can efficiently conduct heat, the heat-conducting fin 5 can be pulled to slide in the cavity 3, which can not only change the position of the heat-conducting fin 5 in the cavity 3, but also can combine multiple heat-conducting fins 5 to improve the density of heat absorption and heat conduction, so as to improve the heat conduction effect.

[0037] Moreover, it needs to explain, before adjusting the position of the heat conduction fin 5, pulling the pull block 10 downward can make the positioning strip 7 compress the supporting spring 8 to slide in the sliding groove 6, so that the heat conduction fin 5 can slide normally. After adjusting the position of the heat conduction fin 5, releasing the pull block 10 can make the supporting spring 8 push the positioning strip 7 out of the sliding groove 6 and into the clamping groove 9 due to its own elastic force, which can ensure the stability of the heat conduction fin 5 and avoid the problem of deviation of the heat conduction fin 5 due to external vibration. By setting the permanent magnet 11, the positioning strip 7 can be adsorbed when it contacts the permanent magnet 11, which can simply position the positioning strip 7 and facilitate personnel to slide the heat conduction fin 5.
