Description

Technical Field

[0001] The utility model belongs to the technical field of temperature balancing plate manufacturing, and particularly relates to a water injection and nitrogen blowing device for an ultra-thin temperature balancing plate. Background Art

[0002] Ultra-thin temperature equalizer (hereinafter referred to as temperature equalizer), also known as ultra-thin VC board, is commonly used for heat dissipation of electronic devices such as mobile phones or laptops. During the manufacturing of existing temperature equalizers, water needs to be injected into the temperature equalizer using an injection needle, and the evaporation of water and the movement of water vapor from the hot end to the cold end are used to realize heat dissipation. However, due to the small internal space of the ultra-thin temperature equalizer and the slow internal capillary water absorption, liquid is retained at the water injection nozzle during injection, which can easily cause liquid overflow, resulting in inaccurate internal sealing volume of the temperature equalizer product and product failure.

[0003] Patent announcement number CN116634739A discloses a mechanism for injecting water and blowing nitrogen into an ultra-thin temperature-averaging plate, comprising a gas-liquid separator having a gas passage and a liquid passage, one end of the gas-liquid separator being connected to a locking cylinder, the other end of the locking cylinder being connected to an injection needle, the injection needle being connected to the water injection port of the temperature-averaging plate, and the gas-liquid separator being used to inject liquid and gas into the temperature-averaging plate at intervals. The present invention injects nitrogen into the product through the gas passage, pressurizes the water injection port of the temperature-averaging plate, and causes the liquid remaining on the product nozzle to flow into the interior of the product capillary structure, thereby reducing the outflow of liquid and improving the yield of the temperature-averaging plate. In this embodiment, nitrogen is selected as the gas to avoid oxidation inside the temperature-averaging plate.

[0004] However, there are currently the following problems with nitrogen blowing: water leakage is prone to occur during water injection, which may cause corrosion, rust or damage to the liquid connection pipes of the gas-liquid isolator and nearby equipment components. Long-term water accumulation or humidity may affect the normal operation of the equipment. Therefore, we proposed an ultra-thin temperature-stabilizing plate water injection and nitrogen blowing device. Utility Model Content

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, an ultra-thin temperature-vaporizing plate water injection and nitrogen blowing device includes a gas-liquid separator 1, an annular groove is formed at the bottom of the gas-liquid separator 1, a liquid connecting pipe 11 is fixedly passed through the top of the gas-liquid separator 1, a needle fixing tube 12 is fixedly passed through the bottom of the gas-liquid separator 1, a gas interface 13 is formed on the side of the gas-liquid separator 1, a gas outlet 14 is formed at the bottom of the gas-liquid separator 1, the needle fixing tube 12 and the gas outlet 14 are both formed within the range of the annular groove, a gas passage 15 is formed inside the gas-liquid separator 1, and a sealing device 2 is provided on the top of the liquid connecting pipe 11;

[0026] The sealing device 2 includes a connecting ring 21, the inner wall of the connecting ring 21 is fixedly connected to the circumferential surface of the liquid connecting pipe 11, and the side of the connecting ring 21 is fixedly connected to an annular airbag 22, and the annular airbag 22 is used to prevent liquid leakage. The top of the gas-liquid isolator 1 is fixedly connected to a hollow circular plate 23, and a threaded groove 24 is provided on the side of the hollow circular plate 23. The threaded groove 24 is used to provide a movement trajectory of the connecting rod 25. The inner wall of the threaded groove 24 is slidably connected to the connecting rod 25, and one end of the connecting rod 25 is fixedly connected to a connecting block 26, and the end of the connecting block 26 away from the connecting rod 25 is fixedly connected to an extrusion ring 27, and the side of the hollow circular plate 23 is fixedly connected to a slot plate 28.

[0027] According to the above structure, water is injected into the liquid connecting pipe 11 through the water injection pipe, so that the water is injected into the interior of the temperature equalizing plate through the liquid connecting pipe 11 and the water injection port of the temperature equalizing plate, and during the water injection process, the water injection is intermittently stopped, and nitrogen is injected into the product through the gas passage 15. At the same time, the connecting block 26 is pushed. The connecting block 26 begins to move after receiving the driving force. When the connecting block 26 begins to move, the connecting block 26 drives the connecting rod 25 to rotate and move upward along the trajectory of the threaded groove 24. When the connecting rod 25 rotates and moves upward, the connecting rod 25 drives the extrusion ring 27 to rotate and move upward.

[0028] like Figure 2 As shown, the inner wall of the extrusion ring 27 is slidably connected to the circumferential surface of the liquid connecting pipe 11. The top of the extrusion ring 27 is provided with an inclined surface. The inclined surface causes the annular airbag 22 to begin to squeeze upward, and the bottom of the annular airbag 22 is located on the displacement track of the extrusion ring 27. The side of the slot plate 28 is located on the displacement track of the connecting rod 25. The slot plate 28 is used to fix the connecting rod 25 and is set to a resilient material.

[0029] According to the above structure, when the extrusion ring 27 moves upward, the extrusion ring 27 squeezes the annular airbag 22 above, and the annular airbag 22 begins to move upward after receiving the extrusion force from the extrusion ring 27. When the annular airbag 22 moves upward, the annular airbag 22 seals the connection between the water injection pipe and the liquid connecting pipe 11. At the same time, when the connecting rod 25 moves, the side of the connecting rod 25 is clamped to the side of the slot plate 28, so that the connecting rod 25 is clamped to the side of the slot plate 28, which can effectively prevent water leakage, thereby protecting the gas-liquid isolator 1 and its surrounding environment from water damage, ensuring that the device maintains efficient operation, and reducing unnecessary energy and resource waste.

[0030] like Figure 5 As shown, a cleaning device 3 is provided on the top of the gas-liquid isolator 1, and the cleaning device 3 includes a push rod 31, one end of the push rod 31 passes through and is slidably connected to the top of the gas-liquid isolator 1, the circumferential surface of the push rod 31 is fixedly connected to a sealing ring, one end of the push rod 31 is fixedly connected to a push block 32, the circumferential surface of the push rod 31 is fixedly sleeved with a spring 33, the end of the spring 33 away from the push rod 31 is fixedly connected to the top of the gas-liquid isolator 1, the spring 33 is used to provide a reset effect for the structure, the inner wall of the gas passage 15 is fixedly connected to an elastic telescopic rod 34, the end of the elastic telescopic rod 34 away from the gas passage 15 is fixedly connected to a circular plate 35, the side of the circular plate 35 is fixedly connected to a fixed rod 36, and the circumferential surface of the fixed rod 36 is fixedly connected to a plurality of annular scrapers 37. The arrangement of the annular scrapers 37 enables the inner wall of the gas passage 15 to be scraped, and the top of the circular plate 35 is fixedly connected to a triangular block 38.

[0031] According to the above structure, when use is completed, the connecting block 26 is pushed, and the connecting block 26 drives the connecting rod 25 to disengage from the slot plate 28, so that the connecting rod 25 begins to rotate and move downward along the trajectory of the threaded groove 24. When the connecting rod 25 moves downward, the connecting rod 25 is squeezed onto the protrusion at the bottom of the push rod 31 below. After the protrusion is squeezed by the squeezing force from the connecting rod 25, it begins to drive the push rod 31 to move downward. When the push rod 31 moves downward, the push rod 31 is squeezed onto the spring 33 below. At the same time, when the push rod 31 moves downward, the push rod 31 drives the push block 32 below. It also starts to move downward. When the pushing block 32 moves downward, the pushing block 32 squeezes the triangular block 38 below. After receiving the squeezing force from the pushing block 32, the triangular block 38 starts to move outward. When the triangular block 38 moves outward, the triangular block 38 drives the bottom circular plate 35 to move outward. When the circular plate 35 moves outward, the circular plate 35 is stretched to the elastic telescopic rod 34 on the side. At the same time, when the circular plate 35 moves outward, the circular plate 35 drives the side fixing rod 36 to move outward. When the fixing rod 36 moves outward, the fixing rod 36 drives the annular scraper 37 to move outward.

[0032] like Figure 5 As shown, the side of the annular scraper 37 contacts the inner wall of the gas passage 15. The bottom of the push block 32 is provided with an inclined surface. The inclined surface allows the triangular block 38 to move outward, and the top of the triangular block 38 is located on the displacement trajectory of the push block 32. The top of the push rod 31 is fixedly connected to a protrusion. The protrusion on the top of the push rod 31 is located on the displacement trajectory of the connecting rod 25. The bottom of the circular plate 35 is slidably connected to the inner wall of the gas passage 15.

[0033] When the push rod 31 moves upward, the pushing rod 31 drives the pushing block 32 to move upward. When the pushing block 32 moves upward, the squeezing force of the pushing block 32 on the triangular block 38 disappears. Then, the triangular block 38 starts to move inward through the elastic force of the elastic telescopic rod 34 on the side of the circular plate 35. When the circular plate 35 moves inward, the circular plate 35 drives the fixing rod 36 to move inward. When the fixing rod 36 moves inward, the fixing rod 36 drives the annular scraper 37 to move inward, thereby causing the annular scraper 37 to move left and right. When the annular scraper 37 moves left and right, the annular scraper 37 scrapes the inner wall of the gas passage 15, thereby removing attached dirt and sediment and keeping the passage unobstructed. This can improve gas flow efficiency and reduce flow resistance, thereby optimizing the gas transmission and separation process.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
