Description

Technical Field

[0001] This utility model relates to the technical field of thermal conductive material packaging, and in particular to a thermal conductive paste packaging. Background Technology

[0002] Currently, gallium-based liquid metal composite thermal paste has become an important choice for thermal interface materials of high-power-density electronic devices (such as CPUs, GPUs, and power modules) due to its extremely high thermal conductivity (5–10 times that of traditional silicone grease). However, its widespread application still faces multiple technical challenges.

[0003] Gallium-based liquid metals are highly susceptible to oxidation in air, rapidly forming a gallium oxide (Ga2O3) film on their surface. This leads to increased viscosity and decreased fluidity, affecting not only coating uniformity but also reducing thermal conductivity. Therefore, effectively isolating the product from oxygen during storage and use is crucial for ensuring stable product performance. Existing technologies suffer from problems such as easy oxidation, inconvenient coating, and complex operation, hindering the widespread application of gallium-based liquid metal thermal pastes.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1 to 11 As shown, a preferred embodiment of the present invention provides a thermal paste package, including a tube 10 and a plurality of replaceable coating parts 20; The hose 10 includes a hose body 11, a grease outlet connector 13, and a sealing membrane 15. The hose body 11 is provided with a receiving cavity 12 for containing thermal conductive grease. The grease outlet connector 13 is located at one end of the hose body 11 and is provided with a grease outlet 14. The grease outlet 14 is connected to the receiving cavity 12 and is sealed to the sealing membrane 15. The coating component 20 includes a base 21 and a coating head 23 connected to one end of the base 21. The coating head 23 is provided with a paste channel 24, and the base 21 is provided with a paste outlet channel 22. The coating head 23 is connected to one end of the base 21, and the other end of the base 21 is detachably connected to the paste outlet connector 13. One end of the paste outlet channel 22 is connected to the paste channel 24, and the other end is connected to the paste outlet 14. The coating heads 23 of the multiple coating parts 20 have different shapes.

[0032] This utility model discloses a thermal paste packaging system. The paste outlet 14 is located on the paste connector 13 of the flexible tube 10. The paste outlet 14 is sealed to a sealing film 15, which blocks the paste from contacting air. The sealing film 15 is only broken when the coating component 20 is installed, preventing premature exposure of the paste within the receiving cavity 12, maximizing shelf life, and achieving a sealed, oxidation-proof design. Each coating component 20 includes a base 21 and a coating head 23, with each coating head 23 having a different shape to accommodate different coating functions and achieve diversified coating. The coating component 20 is detachably connected to the paste outlet 13 of the flexible tube 10 via the base 21, allowing users to detach and reattach the coating component 20 from the flexible tube 10 without additional tools, improving ease of use. After installing the coating component 20 on the flexible tube 10, the paste can be dispensed directly from the paste outlet 14 by squeezing the tube body 11 of the flexible tube 10, eliminating the need for intermediate operations such as paste transfer and scraping, further enhancing ease of use.

[0033] In one embodiment, the sealing membrane 15 is an aluminum-plastic composite membrane. The aluminum-plastic composite membrane has good barrier properties, effectively preventing oxygen and moisture, and preventing the thermal grease from oxidizing and deteriorating.

[0034] In one embodiment, the tube body 11 includes a barrier layer and a protective layer from the inside out, wherein the barrier layer is soluble polytetrafluoroethylene, i.e., PFA, and the protective layer is plastic.

[0035] In one embodiment, one end of the tube body 11 is heat-sealed, and the other end is connected to a paste dispensing connector 13. The paste dispensing connector 13 is made of rigid plastic and forms a paste dispensing port 14. The paste dispensing port 14 is sealed with a sealing film 15 by heat pressing.

[0036] Furthermore, such as Figures 3 to 5As shown, one of the coating components 20 is defined as the first coating component 30, the base 21 of the first coating component 30 is defined as the first base 32, and the coating head 23 of the first coating component 30 is defined as the first coating head 31. The first coating head 31 is spherical and is rotatably connected to one end of the first base 32. The first base 32 is provided with a paste dispensing channel 22, and the end of the first base 32 away from the first coating head 31 is threadedly connected to the paste dispensing connector 13. The spherical coating head 23 is rotatably connected to the first base 32. When the user applies pressure to the tube body 11 and moves the hose 10, the first coating head 31 can roll freely on the contact surface, causing the paste to spread evenly. This is particularly suitable for dot or line coating of planar devices such as CPUs or GPUs. The first coating component 30 is threadedly connected to the paste dispensing connector 13. If the ball is contaminated or worn, the entire module can be replaced directly without cleaning or disassembly, simplifying maintenance and extending the service life of the main packaging.

[0037] As one embodiment, such as Figures 3 to 5 As shown, the first coating head 31 is a ceramic ball. Ceramic balls are hard, wear-resistant, and do not react with liquid metal, avoiding contamination. The surface of the ceramic balls is smooth, allowing for smooth rolling and uniform paste application. They also possess insulation properties, ensuring safe use and extending module lifespan.

[0038] Furthermore, such as Figures 3 to 5 As shown, the first base 32 has a slot 33 at one end facing the first coating head 31. The first coating head 31 is rotatably connected to the slot 33. The slot 33 has a first latch 34 and a second latch 35 that are interconnected. The diameters of the first latch 34 and the second latch 35 are smaller than the diameter of the first coating head 31. The second latch 35 is connected to the paste dispensing channel 22. A paste dispensing channel 24 is formed between the first coating head 31 and the inner peripheral wall of the spherical slot 33. The first base 32 has a slot 33 to accommodate and limit the spherical coating head 23. The diameters of the first latch 34 and the second latch 35 are both smaller than the diameter of the first coating head 31, achieving mechanical limitation of the first coating head 31 being embedded in the slot 33 but able to rotate. The second slot 35 is connected to the paste outlet channel 22. The paste in the tube body 11 enters the slot 33 from the inside of the first base 32 through the second slot 35. The gap formed between the first coating head 31 and the inner peripheral wall of the slot 33 is the paste outlet channel 24. The paste flows into the paste outlet channel 24 through the second slot 35 and is then squeezed out as the first coating head 31 rolls.

[0039] Furthermore, such as Figures 3 to 5 As shown, the inner wall of the slot 33 is arc-shaped, and the diameter 'a' of the first coating head 31 is set between 1mm and 5mm. The arc-shaped inner wall of the slot 33 fits more closely with the first coating head 31, ensuring smooth rotation and uniform paste application. The spherical first coating head 31 with a diameter of 1mm–5mm is suitable for coating various electronic components, offering strong practicality and stable and reliable operation.

[0040] Furthermore, such as Figures 6 to 7 As shown, one of the coating elements 20 is defined as the second coating element 40, the base 21 of the second coating element 40 is defined as the second base 43, and the coating head 23 of the second coating element 40 is defined as the second coating head 41. The second base 43 is provided with a paste dispensing channel 22, and the second coating head 41 is needle-shaped. The end of the second coating head 41 away from the second base 43 is provided with a second coating surface 42, and the second coating head 41 is provided with a paste dispensing channel 24, one end of which penetrates the second coating surface 42. The needle-shaped second coating head 41 dispenses paste in a concentrated manner, enabling precise coating in narrow areas and avoiding overflow. The axial paste dispensing channel 22 ensures stable paste flow, making it suitable for fine operations such as product gaps, improving coating accuracy and controllability.

[0041] In one embodiment, the second coating head 41 is a polytetrafluoroethylene (PTFE) needle. The PTFE needle has a smooth inner wall and strong chemical inertness, making it difficult for the paste to adhere, ensuring smooth and unobstructed paste dispensing; it is corrosion-resistant, does not contaminate the thermal paste, ensures long-term stability of fine coating, and is easy to maintain.

[0042] Furthermore, such as Figures 6 to 7 As shown, the outer diameter of the second coating head 41 is set between 1.5mm and 5.5mm, and the diameter b of the paste channel 24 is set between 1mm and 5mm. The needle-shaped second coating head 41, with an outer diameter of 1.5mm–5.5mm and a channel diameter of 1mm–5mm, is suitable for coating gaps of different widths, ensuring smooth paste dispensing and preventing clogging. It balances structural strength and flow control, improving the accuracy and efficiency of fine operations.

[0043] Furthermore, such as Figures 8 to 9 As shown, one of the coating components 20 is defined as the third coating component 50, the base 21 of the third coating component 50 is defined as the third base 53, and the coating head 23 of the third coating component 50 is defined as the third coating head 51. The third base 53 is provided with a paste dispensing channel 22. The third coating head 51 is flat, and a third coating surface 52 is provided at the end of the third coating head 51 away from the third base 53. The third coating head 51 is provided with a paste dispensing channel 24, one end of which penetrates the third coating surface 52. The width c of the third coating surface 52 is set between 5mm and 10mm, and the width of the end of the paste dispensing channel 24 facing the third coating surface 52 corresponds to the width of the third coating surface 52. The width of the flat third coating head 51 is set between 5mm and 10mm, which is suitable for common chip areas, enabling large-area coating to be completed in one go. This method is highly efficient, avoids uneven coating caused by manual scraping, and improves coating quality.

[0044] As one embodiment, such as Figures 8 to 9As shown, the thickness of the third coating head 51 is set between 1mm and 5mm. It possesses moderate elasticity while ensuring sufficient strength, resulting in good adhesion and uniform coating; it is not easily deformed, can be reused repeatedly, and improves the stability and durability of large-area coating.

[0045] As one embodiment, the paste dispensing channel 22 is the same width as the third coating surface 52, thereby improving the uniformity of paste dispensing from the third coating surface 52 in the width direction.

[0046] Furthermore, such as Figures 10 to 11 As shown, one of the coating elements 20 is defined as the fourth coating element 60, the base 21 of the fourth coating element 60 is defined as the fourth base 64, and the coating head 23 of the fourth coating element 60 is defined as the fourth coating head 61. The fourth base 64 is provided with a paste dispensing channel 22, and the fourth coating head 61 is a brush head. The end of the fourth coating head 61 away from the fourth base 64 is provided with a fourth coating surface 65. The brush head includes multiple brush strips 62 connected to the fourth base 64, and paste channels 24 are formed between adjacent brush strips 62. The fourth coating head 61 is a brush head, and the brush head includes multiple brush strips 62. One end of the brush strips 62 is connected to the fourth base 64 for fixation. The gap between adjacent brush strips 62 forms a paste channel 24, which is suitable for irregular surfaces and precision components, such as GPU memory areas, to avoid damage and improve coating adaptability and safety.

[0047] As one embodiment, such as Figures 10 to 11 As shown, the fourth coating head 61 is a silicone brush head. The silicone brush head is flexible and wear-resistant, conforms to irregularly shaped surfaces without damaging components; it has good chemical stability, does not easily adhere to paste, is easy to clean, and improves the safety and reusability of fine coating.

[0048] As one embodiment, such as Figures 10 to 11 As shown, the fourth base 64 has multiple paste-applying holes 63 on one end face facing the fourth coating head 61. The paste-applying holes 63 are located between adjacent brush strips 62 and communicate with the paste-applying channel 22. The paste-applying holes 63 extend from the outlet of the paste-applying channel 22 and are positioned in the gaps between the brush strips 62 to ensure that the paste is evenly delivered from inside the fourth base 64 to each brush strip 62, avoiding local interruption or blockage.

[0049] Furthermore, such as Figures 10 to 11 As shown, the width d of the fourth coating head 61 is set between 5mm and 20mm to cover the coating needs of products ranging from narrow slits to medium-sized areas. The thickness e of the fourth coating head 61 is set between 1mm and 5mm to ensure that the brush head has a certain structural strength while having good flexibility to adapt to slightly uneven surfaces or low gap spaces, avoid damaging components, and improve operational safety and applicability.

[0050] Furthermore, such as Figure 2As shown, the coating component 20 also includes a cover 25, which has a cavity with an opening facing the coating head 23. The coating head 23 extends into the cavity to achieve physical isolation. The cover 25 covers the outer peripheral surface of the base 21, forming a sealed package. The cover 25 covers the coating head 23, preventing dust and oxidation, and avoiding contamination and damage.

[0051] In one embodiment, the cover 25 is threadedly connected to the coating head 23.

For example, the user selects the flat third coating head 51 for the CPU top cover.

[0053] 2. Activation: Unscrew the cap 25. At this time, the sealing film 15 is still intact and the paste is not exposed.

[0054] 3. Connection and Deseal Breaking: Connect the selected coating component 20 to the paste dispensing connector 13. During tightening, a spike structure inside the coating component 20 (not shown in the figure) will pierce the sealing membrane 15, allowing the paste to flow into the paste dispensing channel 22 and reach the selected coating hole. Alternatively, the sealing membrane 15 can be torn beforehand before connecting the coating component 20 to the paste dispensing connector 13.

[0055] 4. Coating: Squeeze the flexible packaging bag, and the paste will flow out from the selected coating head 23 and be directly coated on the target surface.

Each coating component 20 includes a base 21 and a coating head 23, and the shape of the coating head 23 of each coating component 20 is different, thus satisfying different coating functions and achieving diversified coating. The coating component 20 is detachably connected to the paste outlet 13 of the flexible tube 10 via the base 21, allowing users to detach and install the coating component 20 from the flexible tube 10 without additional tools, improving ease of use. With the coating component 20 installed on the flexible tube 10, the paste can be dispensed directly from the paste outlet 14 by squeezing the tube body 11 of the flexible tube 10, eliminating the need for intermediate operations such as paste transfer and scraping, further improving ease of use.
