Description

Technical Field

[0001] The present application relates to the technical field of heat sink gaskets, and in particular to a heat sink gasket. Background Art

[0002] The so-called heat sink refers to an object whose temperature does not change with the amount of heat energy transferred to it. It can be objects such as the atmosphere and the earth. In industry, it refers to a micro heat sink, a device used to cool electronic chips.

[0003] The existing patent (publication number: CN207688707U) discloses a heat sink gasket, including a gasket body, a heat dissipation hole is opened at the bottom of the gasket body, a bracket located at the bottom of the heat dissipation hole is movably installed at the bottom of the gasket body, a micro motor is fixedly connected to the inside of the bracket, a connecting block is fixedly connected to the rotating shaft of the micro motor, a fan blade is fixedly connected to the surface of the connecting block, the bottom of the gasket body is fixedly connected to support blocks located on both sides of the heat dissipation hole, the bottom of the support block is fixedly connected to a support column, the length of the support column is greater than the thickness of the bracket, the top of the bracket is movably connected to the bottom of the support block, and both sides of the bracket are fixedly connected to receiving blocks.

[0004] The above-mentioned comparative document points out that the heat sink gasket can improve the heat dissipation effect of the gasket body by opening heat dissipation holes, so that in cooperation with the micro motor, the connecting block and the fan blades, the heat can be quickly dissipated, thereby improving the heat dissipation efficiency and being able to adapt to occasions with high heat dissipation requirements, making it convenient for people to use. However, in a high temperature environment, the air volume generated by the fan may not be sufficient to effectively dissipate the heat. When the ambient temperature approaches or exceeds the designed operating temperature of the fan, the heat dissipation effect of the fan will be significantly reduced, and the wind generated by the fan may not be sufficient to cool it. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a heat sink gasket with advantages such as improved cooling efficiency, and solves the problem that the heat sink gasket can improve the heat dissipation effect of the gasket body by opening heat dissipation holes, so that it can cooperate with the micro motor, connecting block and fan blades to quickly dissipate heat, thereby improving the heat dissipation efficiency and being able to adapt to occasions with high heat dissipation requirements, making it convenient for people to use. However, in a high temperature environment, the air volume generated by the fan may not be sufficient to effectively dissipate the heat. When the ambient temperature approaches or exceeds the designed operating temperature of the fan, the heat dissipation effect of the fan will be significantly reduced, and the wind generated by the fan may not be sufficient to cool it.

[0006] To achieve the above object, the present application provides the following technical solution: A heat sink gasket, comprising a gasket body, a surrounding plate is fixedly connected to the upper end of the gasket body, a fixing frame is fixedly connected to the upper end of the surrounding plate, a refrigeration chip is fixedly connected inside the fixing frame, a plurality of cooling rods arranged in a rectangular array are fixedly connected to the bottom end of the refrigeration chip, a plurality of ventilation pipes are fixedly connected to both sides of the surrounding plate, a bracket is fixedly connected inside each of the plurality of ventilation pipes, a motor is fixedly connected inside each of the plurality of brackets, and a fan blade is fixedly connected to the output end of each of the plurality of motors.

[0007] Through the above solution, the device can actively reduce the temperature of the gasket body and its contact surface by the combined use of the refrigeration chip and the plurality of cooling rods, achieving efficient thermal management. The motor in the ventilation pipe drives the fan blade to rotate, which can accelerate the air flow. Compared with the traditional passive heat dissipation method, active refrigeration is adopted, which can reduce the temperature more quickly and efficiently. The device dissipates heat by setting active refrigeration and air cooling technologies, achieving an efficient, uniform and reliable heat dissipation effect.

[0008] Further, a dust-proof net is fixedly connected to the side of each of the plurality of ventilation pipes away from the surrounding plate.

[0009] Through the above solution, the dust-proof net can effectively prevent external dust, small particles and other sundries from entering the inside of the ventilation pipe, ensuring the cleanliness of key components such as the fan blade and the motor, thereby prolonging their service life and ensuring the heat dissipation performance.

[0010] Further, a ventilation groove is opened inside the gasket body, a plurality of ventilation holes arranged in a rectangular array are opened at the upper end of the gasket body, and a plurality of first heat dissipation fins arranged in a linear array are fixedly connected inside the ventilation groove.

[0011] Through the above solution, the design of the ventilation groove and the ventilation holes can increase the channels for air circulation, making it easier for heat to dissipate from the gasket body, thereby improving the overall heat dissipation performance. In a high-temperature environment, the temperature of the device can be effectively reduced.

[0012] Further, a heat sink is fixedly connected to the upper end of the fixing frame, and a plurality of second heat dissipation fins arranged in a linear array are fixedly connected to the upper end of the heat sink.

[0013] Through the above solution, the heat sink and the second heat dissipation fins are used to dissipate heat for the refrigeration chip.

[0014] Further, each of the plurality of fan blades is rotatably arranged inside the ventilation pipe.

[0015] Through the above solution, the fan blade rotates inside the ventilation pipe, which can ensure that the air flow flows along a specific path, thereby optimizing the heat dissipation effect.

[0016] Furthermore, both the gasket body and the first heat dissipation fin are made of metal copper material.

[0017] Through the above solution, metal copper is a material with excellent thermal conductivity, and its thermal conductivity coefficient is much higher than that of other common metals. The gasket body and the first heat dissipation fin made of copper material can quickly transfer heat from the heat source to the heat dissipation surface, improving the heat dissipation efficiency.

[0018] Furthermore, both the heat sink and the second heat dissipation fin are made of aluminum alloy material.

[0019] Through the above solution, the aluminum alloy has a low density. Compared with other metal materials such as steel, it is lighter in weight while maintaining a certain strength. This enables the heat sink and the second heat dissipation fin to reduce the overall weight while providing heat dissipation performance.

[0020] Furthermore, all of the plurality of cooling rods are made of stainless steel material.

[0021] Through the above solution, the cooling rods are made of stainless steel material, which has the characteristics of corrosion resistance and high strength, and can ensure the long-term stable operation of the device.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] For this heat sink gasket, by using the cooperation of the refrigerating sheet and the plurality of cooling rods, the device can actively reduce the temperature of the gasket body and its contact surface, realizing efficient thermal management. The motor in the ventilation pipe drives the fan blade to rotate, which can accelerate air flow. Compared with the traditional passive heat dissipation method, active refrigeration is adopted, which can reduce the temperature more quickly and efficiently. The device dissipates heat by setting active refrigeration and air-cooling technologies, achieving an efficient, uniform, and reliable heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , a heat sink gasket in this embodiment includes a gasket body 1. An enclosure 2 is fixedly connected to the upper end of the gasket body 1. A fixed frame 3 is fixedly connected to the upper end of the enclosure 2. A thermoelectric cooler 4 is fixedly connected inside the fixed frame 3. A plurality of cooling rods 5 arranged in a rectangular array are fixedly connected to the bottom end of the thermoelectric cooler 4. A plurality of ventilation pipes 6 are fixedly connected to both sides of the enclosure 2. Brackets 7 are fixedly connected inside the plurality of ventilation pipes 6. Motors 8 are fixedly connected inside the plurality of brackets 7. Fan blades 9 are fixedly connected to the output ends of the plurality of motors 8. Through the combined use of the thermoelectric cooler 4 and the plurality of cooling rods 5, the device can actively reduce the temperature of the gasket body 1 and its contact surface, achieving efficient thermal management. The motor 8 in the ventilation pipe 6 drives the fan blade 9 to rotate, which can accelerate air flow.

[0032] Please refer to Figure 2 , Figure 3 and Figure 4 , dust filters 10 are fixedly connected to the sides of the plurality of ventilation pipes 6 away from the enclosure 2. The dust filters 10 can effectively prevent external dust, small particles and other sundries from entering the inside of the ventilation pipes 6, ensuring the cleanliness of key components such as the fan blades 9 and the motors 8, thereby extending their service life and ensuring the heat dissipation performance. Ventilation grooves 11 are provided inside the gasket body 1. A plurality of ventilation holes 12 arranged in a rectangular array are provided at the upper end of the gasket body 1. A plurality of first heat sink fins 13 arranged in a linear array are fixedly connected inside the ventilation grooves 11. The design of the ventilation grooves 11 and the ventilation holes 12 can increase the channels for air circulation, making it easier for heat to dissipate from the gasket body 1, thereby improving the overall heat dissipation performance. In a high-temperature environment, the temperature of the device can be effectively reduced. A heat sink 14 is fixedly connected to the upper end of the fixed frame 3. A plurality of second heat sink fins 15 arranged in a linear array are fixedly connected to the upper end of the heat sink 14. The heat sink 14 and the second heat sink fins 15 are used to dissipate heat for the thermoelectric cooler 4.

[0033] Please refer to Figure 2 and Figure 3 Multiple fan blades 9 are rotatably arranged inside the ventilation pipe 6. The rotation of the fan blades 9 inside the ventilation pipe 6 can ensure that the air flow flows along a specific path, thereby optimizing the heat dissipation effect. The gasket body 1 and the first heat dissipation fins 13 are both made of copper. Copper is a material with excellent thermal conductivity, and its thermal conductivity coefficient is much higher than that of other common metals. The gasket body 1 and the first heat dissipation fins 13 made of copper can quickly transfer heat from the heat source to the heat dissipation surface, improving the heat dissipation efficiency. The heat sink 14 and the second heat dissipation fins 15 are both made of aluminum alloy. Aluminum alloy has a low density. Compared with other metal materials such as steel, it is lighter in weight while maintaining a certain strength. This enables the heat sink 14 and the second heat dissipation fins 15 to reduce the overall weight while providing heat dissipation performance. Multiple cooling rods 5 are all made of stainless steel. The cooling rods 5 made of stainless steel have the characteristics of corrosion resistance and high strength, which can ensure the long-term stable operation of the device.

[0034] In this embodiment, for this heat sink gasket, the device can actively reduce the temperature of the gasket body 1 and its contact surface through the combined use of the Peltier cooler 4 and multiple cooling rods 5, achieving efficient thermal management. The motor 8 in the ventilation pipe 6 drives the fan blade 9 to rotate, which can accelerate the air flow. Compared with the traditional passive heat dissipation method, active refrigeration can more quickly and efficiently reduce the temperature. The device uses active refrigeration and air-cooling technology for heat dissipation, achieving an efficient, uniform, and reliable heat dissipation effect.

[0035] The working principle of the above embodiment is as follows:

[0036] When the device starts to operate and generate heat, the heat sink gasket starts to work. The Peltier cooler 4 and the motor 8 are powered on and ready to enter the working state. The Peltier cooler 4 starts to work, uses the thermoelectric effect to produce a refrigeration effect to cool the air, and then transfers it to the gasket body 1 and its contact surface to reduce its temperature. The motor 8 starts and drives the fan blade 9 to rotate inside the ventilation pipe 6. The rotation of the fan blade 9 accelerates the air flow, forming an air current. The air current passes through the ventilation holes 12 and ventilation grooves 11 of the gasket body 1, taking away the heat on the gasket body 1 and the first heat dissipation fins 13. The heat is taken out together with the air current, improving the heat dissipation efficiency. At the same time, to ensure the heat dissipation effect of the Peltier cooler 4, the heat sink 14 and the second heat dissipation fins 15 start to play a role in dissipating heat for the Peltier cooler 4.
