Description

TECHNICAL FIELD

[0001] The utility model relates to the field of temperature equalizing plate, and specifically, in particular to a temperature equalizing plate liquid injection structure and temperature equalizing plate. BACKGROUND

[0002] In the field of ultra-thin temperature equalizing plate manufacturing, the traditional single-channel liquid injection method has long been restricted by production efficiency and product quality due to its inherent defects. High-pressure gas injection not only may cause the expansion and deformation of the temperature equalizing plate structure, damaging the appearance and dimensional stability, but also, in the exhaust stage after work, the accompanying gas injection may unintentionally take away a certain amount of working liquid, directly affecting the accuracy of the internal liquid content of the temperature equalizing plate, making it difficult to meet the preset standards.

[0003] In addition, the at least 2mm thick liquid injection structure in the traditional design can meet the connection requirements of the 2mm diameter liquid injection pipe, but it also seriously hinders the parallel stacking and storage of the temperature equalizing plate without removing the liquid injection structure, occupying a large amount of space and increasing the risk of deformation during the turnover process. In automated operation, the lack of a unified positioning reference leads to low efficiency, and these problems have become a common problem plaguing the industry. SUMMARY

[0004] Therefore, the utility model provides a temperature equalizing plate liquid injection structure and temperature equalizing plate, which injects liquid by suction force, guides the working liquid to flow into the temperature equalizing plate cavity gently and accurately, completely eliminates the problem of gas spouting out of the liquid injection port, and ensures that the working liquid content can reach the set value. At the same time, thanks to the liquid injection method by suction force, the thickness of the temperature equalizing plate liquid injection structure can be thinned to be comparable to the thickness of the temperature equalizing plate cavity, or even lower, so that the temperature equalizing plate can be stacked in parallel during the processing stage, greatly saving the turnover space and reducing the defective rate, and facilitating the development of automated production.

[0005] The utility model realizes the purpose through the following technical scheme:

[0006] A temperature equalizing plate liquid injection structure is provided, which is in communication with the temperature equalizing plate cavity and is used for injecting liquid into the temperature equalizing plate cavity, comprising a first cover plate, a second cover plate, a first through hole and a second through hole provided on the first cover plate, a first channel in communication with the first through hole and the temperature equalizing plate cavity, and a second channel in communication with the second through hole and the temperature equalizing plate cavity.

[0007] Through the way of suction instead of traditional high-pressure perfusion, the working liquid is guided to flow into the inner cavity of the vapor chamber gently and accurately, which completely eliminates the problem of gas spouting out of the liquid injection port in the past. Thanks to the capillary structure design inside the vapor chamber, the liquid can be fully diffused in the inner cavity space and tightly adsorbed on the wall surface, ensuring a high liquid retention rate and ensuring that the working liquid content can reach the set value. Thanks to the liquid injection method by suction, the thickness of the vapor chamber liquid injection structure can be thinned to the thickness of the inner cavity of the vapor chamber, or even lower, so that the vapor chamber can be stacked in parallel during the processing stage, greatly saving the turnover space and reducing the defective rate. At the same time, it is convenient for the robot to grab and identify, which significantly improves the smoothness of the automatic production line and reduces the delay caused by positioning errors.

[0008] Specifically, the first through hole and the second through hole are independent of each other. When one of the through holes is used as a liquid injection port, the channel connected thereto is used as a liquid injection channel. At the same time, the other through hole is used as an air extraction port, and the channel connected thereto is used as an air extraction channel. The liquid injection port and the air extraction port can be interchanged according to actual conditions. During operation, an air extraction device is connected to the air extraction port, and during the liquid injection process, the air extraction device continuously extracts air from the air extraction port while injecting a set amount of working liquid into the liquid injection port. Because the air extraction port is always in an air-extracted state, the liquid injection port is in an air-inhaling state, and the suction force of the liquid injection port quickly sucks the working liquid into the inner cavity of the vapor chamber. When the working liquid enters the inner cavity of the vapor chamber through the liquid injection channel, the space instantaneously increases and the inner cavity is designed with a capillary structure, so that the working liquid can be fully retained in the inner cavity of the vapor chamber.

[0009] Preferably, the first through hole and the second through hole are circular or polygonal.

[0010] Whether it is a circular or polygonal through hole, it can achieve uniform coverage and ensure that the inner cavity filling degree of each vapor chamber is consistent, thereby improving the consistency and reliability of the product.

[0011] Circular through hole: classic design, thanks to its perfect symmetry, the circular through hole can provide balanced liquid injection effect, which is suitable for most vapor chamber inner cavity structures. It is not only easy to process, but also can maximize the reduction of resistance during liquid flow, thereby promoting the injection speed and efficiency.

[0012] Polygonal through hole: breaking the convention, the polygonal through hole has a unique guiding effect, which can adjust the liquid injection flow direction and rate according to specific needs, and is particularly suitable for vapor chambers with complex inner cavity designs. The multi-angle edges increase the contact area with the inner cavity, ensuring more uniform liquid distribution and avoiding local accumulation.

[0013] Preferably, the first channel is provided on the first cover plate or the second cover plate.

[0014] The first channel is freely arranged on the first cover plate or the second cover plate. The position of the first channel is not fixed, and the installation of the first channel on the first cover plate or the second cover plate can be flexibly determined according to actual production needs. This humanized design consideration fully embodies the flexibility and foresight of engineering design, facilitates later maintenance and upgrading, and also simplifies the equipment debugging process and shortens the production time.

[0015] Preferably, the first channel is stamped and formed on the first cover plate or the second cover plate.

[0016] The metal plate is accurately molded into the required first channel by using a high-pressure device. The edge of the stamped first channel is smooth and has no burrs, ensuring smooth liquid flow and reducing internal loss to improve liquid injection efficiency. The stamped first channel is integrated with the first cover plate (or the second cover plate), which eliminates the need for additional interfaces and sealing treatment. This not only simplifies the production process but also significantly reduces the risk of liquid leakage and improves the reliability and durability of the entire liquid injection system.

[0017] Preferably, the second channel is arranged on the first cover plate or the second cover plate.

[0018] The second channel is freely arranged on the first cover plate or the second cover plate. The position of the second channel is not fixed, and the installation of the second channel on the first cover plate or the second cover plate can be flexibly determined according to actual production needs. This humanized design consideration fully embodies the flexibility and foresight of engineering design, facilitates later maintenance and upgrading, and also simplifies the equipment debugging process and shortens the production time.

[0019] Preferably, the second channel is stamped and formed on the first cover plate or the second cover plate.

[0020] The metal plate is accurately molded into the required second channel by using a high-pressure device. The edge of the stamped second channel is smooth and has no burrs, ensuring smooth liquid flow and reducing internal loss to improve liquid injection efficiency. The stamped second channel is integrated with the first cover plate (or the second cover plate), which eliminates the need for additional interfaces and sealing treatment. This not only simplifies the production process but also significantly reduces the risk of liquid leakage and improves the reliability and durability of the entire liquid injection system.

[0021] Preferably, the first channel and the second channel are separated from each other by a partition.

[0022] The partition clearly separates the liquid injection channel and the air extraction channel by physical separation, so that the air extraction operation is not affected while the liquid is being injected. In this way, the liquid during the liquid injection process will not be disturbed by the air extraction operation, ensuring that the working liquid can smoothly and completely enter the inner cavity of the uniform plate, greatly improving the accuracy and efficiency of the liquid injection.

[0023] Preferably, the partition is stamped and formed on the first cover plate or the second cover plate.

[0024] The partition can be directly arranged on the first cover plate or the second cover plate and directly formed on the surface of the cover plate by stamping process.

[0025] A uniform temperature plate comprises the uniform temperature plate liquid injection structure as described above.

[0026] Preferably, the partition extends into the inner cavity of the uniform temperature plate.

[0027] The partition extending into the inner cavity completely isolates the liquid injection channel and the air extraction channel, avoids the invasion of air or other impurities, and effectively avoids the mixing of external gas during the air extraction process, thereby ensuring the purity of the internal environment, which is crucial for maintaining the thermal stability of the uniform temperature plate.

[0028] Compared with the prior art, the utility model has the beneficial effects that:

[0029] The uniform temperature plate liquid injection structure guides the working liquid to flow into the inner cavity of the uniform temperature plate gently and accurately by suction force instead of the traditional high-pressure injection mode, thereby completely eliminating the problem of air spouting out of the liquid injection port.

[0030] Specifically, the first through hole and the second through hole are independent of each other, when one of the through holes is used as a liquid injection port, the channel communicated with the liquid injection port is used as a liquid injection channel. Meanwhile, the other through hole is used as a gas extraction port, and the channel communicated with the gas extraction port is used as a gas extraction channel; the liquid injection port and the gas extraction port can be interchanged according to actual conditions. During work, a gas extraction device is connected to the gas extraction port, and during the liquid injection process, the gas extraction device is always extracting gas from the gas extraction port, and at the same time, a certain amount of working liquid is injected into the liquid injection port. Because the gas extraction port is always in the state of being extracted, the liquid injection port is in the state of being inhaled, and the suction force of the liquid injection port can quickly suck the working liquid into the inner cavity of the uniform temperature plate. When the working liquid enters the inner cavity of the uniform temperature plate through the liquid injection channel, the space instantaneously increases and the inner cavity is designed with a capillary structure, so that the working liquid can be completely left in the inner cavity of the uniform temperature plate.

Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0035] It should be noted that similar reference numerals and letters refer to like items in the accompanying drawings, and once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings. In the description of embodiments of the present application, it needs to be understood that the terms "upper", "lower", "left", "right", "vertical", "horizontal", and the like are words of convenience and are not to be construed as limiting terms unless otherwise indicated by the context. These terms merely identify the orientation in use or normal position of an item as shown in the figures or as commonly understood by those in the art, and thus can not be construed as specifically related to the particular orientation of the items shown in the figures or as limiting the scope of the claims to only the positional relationships illustrated in the figures.

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0037] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0038] The present embodiment provides a uniform temperature plate, comprising a uniform temperature plate body and a uniform temperature plate liquid injection structure, the uniform temperature plate body is provided with a uniform temperature plate cavity, the uniform temperature plate liquid injection structure is communicated with the uniform temperature plate cavity and is used for injecting liquid into the uniform temperature plate cavity, comprising a first cover plate 1, a second cover plate 2, a first through hole 3 and a second through hole 4 arranged on the first cover plate 1, a first channel 5 communicated with the first through hole 3 and the uniform temperature plate cavity, and a second channel 6 communicated with the second through hole 4 and the uniform temperature plate cavity.

[0039] Through the suction force instead of the traditional high-pressure perfusion mode, the working liquid is guided to flow into the uniform temperature plate cavity gently and accurately, and the problem of the liquid injection port spouting gas outward is completely eliminated. Due to the capillary structure design inside the uniform temperature plate, the liquid can be fully diffused in the cavity space and closely adsorbed on the wall surface, ensuring a high liquid retention rate and ensuring that the working liquid content can reach the set value. Due to the liquid injection mode by suction force, the thickness of the uniform temperature plate liquid injection structure can be thinned to be equivalent to the thickness of the uniform temperature plate cavity, or even lower, so that the uniform temperature plate can be stacked in parallel during the processing stage, greatly saving the turnover space and reducing the defective rate. At the same time, it is convenient for the robot to grasp and identify, significantly improving the smoothness of the automatic production line and reducing the delay caused by positioning errors.

[0040] Specifically, the first through hole 3 and the second through hole 4 are independent of each other. When one of the through holes is used as a liquid injection port, the channel connected therewith is used as a liquid injection channel. Meanwhile, the other through hole is used as an air extraction port, and the channel connected therewith is used as an air extraction channel. The liquid injection port and the air extraction port can be interchanged according to actual conditions. During operation, an air extraction device is connected to the air extraction port, and during the liquid injection process, the air extraction device continuously extracts air from the air extraction port, while the liquid injection port is injected with a predetermined amount of working liquid. Since the air extraction port is always in an air-extracted state, the liquid injection port is in an air-intake state, and the suction force of the liquid injection port rapidly sucks the working liquid into the inner cavity of the vapor chamber. When the working liquid enters the inner cavity of the vapor chamber through the liquid injection channel, the space instantaneously increases, and the inner cavity is designed with a capillary structure, so that the working liquid can be completely retained in the inner cavity of the vapor chamber.

[0041] In this embodiment, the first through hole 3 and the second through hole 4 are circular.

[0042] Circular through hole: classic design, thanks to its perfect symmetry, the circular through hole can provide balanced liquid injection effect, suitable for most vapor chamber inner cavity structures. It is not only easy to process, but also can maximize the reduction of resistance during liquid flow, promoting the injection speed and efficiency.

[0043] In other embodiments, the first through hole 3 and the second through hole 4 can be polygonal.

[0044] Polygonal through hole: breaking the routine, the polygonal through hole has a unique guiding effect, which can adjust the liquid injection flow direction and rate according to specific needs, especially suitable for vapor chambers with complex inner cavity design. The multi-angle edges enhance the contact area with the inner cavity, ensuring more uniform liquid distribution and avoiding local accumulation.

[0045] In this embodiment, the first channel 5 is provided on the second cover plate 2. In other embodiments, the first channel can be provided on the first cover plate.

[0046] Free configuration on the first cover plate 1 or the second cover plate 2: the position of the first channel 5 is not fixed, and can be flexibly determined to be installed on the first cover plate 1 or the second cover plate 2 according to actual production needs. This humanized design consideration fully embodies the flexibility and foresight of engineering design, facilitating later maintenance and upgrading, while also simplifying the equipment debugging process and shortening the production time.

[0047] In this embodiment, the first channel 5 is stamped on the second cover plate 2. In other embodiments, the first channel can be stamped on the first cover plate.

[0048] The first channel 5 is precisely shaped by high-pressure equipment, and the edges of the first channel 5 punched out are smooth and free of burrs, ensuring smooth liquid flow and reducing internal loss to improve liquid injection efficiency. The first channel 5 is integrated with the first cover plate 1 (or the second cover plate 2) by stamping, eliminating the need for additional interfaces and sealing treatment. This not only simplifies the production process but also significantly reduces the risk of liquid leakage, improving the reliability and durability of the entire liquid injection system.

[0049] In this embodiment, the second channel 6 is provided on the second cover plate 2. In other embodiments, the second channel can be provided on the first cover plate.

[0050] The second channel 6 is freely configured on the first cover plate 1 or the second cover plate 2: The position of the second channel 6 is not fixed and can be flexibly determined to be installed on the first cover plate 1 or the second cover plate 2 according to actual production needs. This humanized design consideration fully embodies the flexibility and foresight of engineering design, facilitating later maintenance and upgrading, and also simplifying the equipment debugging process and shortening the production time.

[0051] In this embodiment, the second channel 6 is stamped and formed on the second cover plate 2. In other embodiments, the second channel can be stamped and formed on the first cover plate.

[0052] The second channel 6 is precisely shaped by high-pressure equipment, and the edges of the second channel 6 punched out are smooth and free of burrs, ensuring smooth liquid flow and reducing internal loss to improve liquid injection efficiency. The second channel 6 is integrated with the first cover plate 1 (or the second cover plate 2) by stamping, eliminating the need for additional interfaces and sealing treatment. This not only simplifies the production process but also significantly reduces the risk of liquid leakage, improving the reliability and durability of the entire liquid injection system.

[0053] In this embodiment, the first channel 5 and the second channel 6 are separated from each other by the partition 7.

[0054] By physically separating the liquid injection channel and the air extraction channel, the partition 7 clearly distinguishes between the two, so that the air extraction operation is not affected while the liquid is being injected. In this way, the liquid during the injection process will not be disturbed by the air extraction operation, ensuring that the working liquid can smoothly and completely enter the inner cavity of the uniform plate, greatly improving the accuracy and efficiency of the liquid injection.

[0055] In this embodiment, the partition 7 is stamped and formed on the second cover plate 2. In other embodiments, the partition can be stamped and formed on the first cover plate.

[0056] The partition 7 can be directly arranged on the first cover plate 1 or the second cover plate 2 and directly formed on the surface of the cover plate by a stamping process. Such a design not only simplifies the number of components, reduces potential leakage points, but also helps to speed up the assembly speed and reduce the manufacturing cost. The partition 7 formed by stamping has high structural strength and can work stably in a high-temperature and high-pressure environment for a long time without worrying about aging or damage, thereby providing a reliable guarantee for long-term operation of the liquid injection system.

[0057] In the embodiment, the partition 7 extends into the inner cavity of the uniform temperature plate.

[0058] The partition 7 extending into the inner cavity is like an invincible barrier, which completely isolates the liquid injection channel and the air extraction channel and avoids the invasion of air or other impurities. In particular, during the air extraction process, external gas can be effectively avoided from mixing, thereby ensuring the purity of the internal environment, which is crucial for maintaining the thermal stability of the uniform temperature plate.

[0059] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
