Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of the heat plate, in particular to a heat plate and a processing method thereof. BACKGROUND

[0002] In the prior art, a common way of water injection structure or air extraction structure is to form a pre-designed water injection port on the heat plate by injection molding, and a water injection pipe is used to inject cooling liquid into the heat plate.

[0003] When water is injected from the side of the heat plate, the water injection nozzle needs to be sealed with the water injection port of the heat plate to prevent water leakage and cause the water injection amount in the heat plate to not meet the set amount. When the water injection nozzle and the water injection port of the heat plate form a seal, the air pressure in the heat plate cannot be discharged when water is injected, which causes difficulty in water injection and affects the water injection efficiency. SUMMARY

[0004] In view of the above technical problems, the present application provides a heat plate and a processing method thereof.

[0005] The present application provides a heat plate, which comprises a plate body having an internal cavity, a first water injection port is arranged at one end of the plate body and communicates with the internal cavity, and the heat plate further comprises:

[0006] A removable structure is arranged at one end of the plate body.

[0007] The removable structure is internally provided with a water injection channel and a gas storage chamber communicating with the water injection channel, one end of the water injection channel communicates with the outside, the other end of the water injection channel communicates with the first water injection port, and the gas storage capacity of the gas storage chamber is equal to or greater than the exhaust capacity after the internal cavity is injected with water.

[0008] In some embodiments of the present application, the inner diameter of the gas storage chamber is greater than the inner diameter of the water injection channel.

[0009] In some embodiments of the present application, the water injection channel comprises:

[0010] A section of channel, one end of the section of channel communicates with the gas storage chamber;

[0011] A second section of pressurizing channel, one end of the second section of pressurizing channel communicates with the gas storage chamber.

[0012] In some embodiments of the present application, the removable structure comprises a first removable part and a second removable part which are sealedly connected to each other, and the water injection channel and the gas storage chamber are formed between the first removable part and the second removable part.

[0013] In some embodiments of the present application, the water injection channel comprises a first water injection groove arranged on the first removable part and a second water injection groove arranged on the second removable part.

[0015] In some embodiments of the present application, the gas storage chamber comprises a first gas storage groove arranged on the first removable part and a second gas storage groove arranged on the second removable part.

[0016] In some embodiments of the present application, the gas storage chamber is any one of an elliptical cavity and a rhombic cavity.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] The water injection pipe and the air extraction structure are cancelled, the overall length is reduced, the removable structure is increased, the water injection and air extraction are simultaneously realized through the removable structure, the production process is simplified, the liquid injection stability is improved, the cannula and the UV curing process can be cancelled.

[0019] In use, the second water injection port can be used to inject liquid into the internal cavity of the vapor chamber through the water injection channel by using a water injection device. During the liquid injection process, the gas in the internal cavity is extruded and escapes outward and is stored in the gas storage chamber. Specifically, during the water injection process, the second water injection port is sealingly connected with the water injection needle or the water injection device, so that the air extraction and the gas storage in the gas storage chamber are simultaneously realized during the water injection process.

[0020] It can be understood that, due to the design of the water injection channel and the gas storage chamber, the water injection and air extraction processes can be simultaneously realized, the cannula and the UV curing process are not required, the process flow is simplified, and the production efficiency is greatly improved. In addition, the design of the removable structure makes it convenient to cut off after the water injection and air extraction operations are completed, thereby cancelling the water injection pipe and the air extraction structure and reducing the overall length.

[0021] On the other hand, the present application also provides a processing method of a vapor chamber, comprising:

[0022] S1, fixing the plate body, and sealingly connecting a water injection nozzle to the water injection channel of the removable structure at the water inlet end, and the water injection nozzle is in communication with a water source;

DETAILED DESCRIPTION

[0036] Exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art. 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. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0037] Reference Figure 1 The present embodiment provides a vapor chamber, which includes a plate body 1 having an internal cavity 11, and a first water inlet 12 is provided at one end of the plate body 1 and communicates with the internal cavity 11. The vapor chamber further includes:

[0038] A removable structure 2 is provided at one end of the plate body 1.

[0039] The removable structure 2 is provided with a water injection channel and a gas storage chamber 25 communicating with the water injection channel. One end of the water injection channel communicates with the outside, and the other end of the water injection channel communicates with the first water inlet 12. The gas storage capacity of the gas storage chamber 25 is equal to or greater than the exhaust capacity of the internal cavity 11 after being injected with water.

[0040] Specifically, the removable structure 2 can be removed by any one of shearing and punching.

[0041] It can be understood that the present embodiment cancels the traditional water injection pipe design, simplifies the structure of the vapor chamber, reduces the number of components and potential failure points. Through the removable structure 2, the exhaust and water injection operations can be conveniently performed, and the maintenance efficiency of the vapor chamber is improved. During the water injection process, the internal gas can be effectively discharged and stored in the gas storage chamber 25 of the removable structure 2, avoiding the gas remaining in the vapor chamber, thereby improving the heat conduction efficiency and reliability of the vapor chamber. After the water injection is completed, the first water inlet 12 is sealed and the removable structure 2 is cut or punched, which can ensure the sealing of the vapor chamber and prevent liquid leakage and invasion of external pollutants. Simplifying the structure and reducing the number of components helps to reduce production costs, while improving the market competitiveness of the product.

[0042] ReferenceFigures 3-4 In one embodiment of the present application, the inner diameter of the gas storage chamber 25 is greater than the inner diameter of the water injection channel.

[0043] Specifically, the inner diameter of the gas storage chamber 25 in the present embodiment is greater than the inner diameter of the water injection channel, ensuring that there is sufficient space in the gas storage chamber 25 to store the amount of exhaust gas discharged after the internal cavity 11 is injected with water.

[0044] Referring to Figure 2 and Figure 5 In one embodiment of the present application, the water injection channel comprises:

[0045] a first channel 21, one end of the first channel 21 being in communication with the gas storage chamber 25;

[0046] a second pressurizing channel 22, one end of the second pressurizing channel 22 being in communication with the gas storage chamber 25.

[0047] Specifically, the first channel 21 in the present embodiment is used for sealed connection with the water injection device, and the water injection device injects water into the internal cavity 11 of the plate body 1 through the first channel 21, the gas storage chamber 25, and the second pressurizing channel 22.

[0048] Specifically, the two ends of the second pressurizing channel 22 in the present embodiment are in communication with the gas storage chamber 25 and the first water injection port 12, respectively, wherein the inner diameter of the end of the second pressurizing channel 22 in communication with the gas storage chamber 25 is greater than the inner diameter of the end of the second pressurizing channel 22 in communication with the first water injection port 12, thereby forming a tapered section in the middle section of the second pressurizing channel 22.

[0049] It can be understood that in the present embodiment, the inner diameter of the second pressurizing channel 22 in the water injection direction gradually decreases, and the middle section is tapered, so that when the water flow passes through the second pressurizing channel 22 during the water injection process, the water flow velocity increases due to the gradual decrease in the inner diameter, thereby pressurizing the water flow. The pressurization not only improves the water injection efficiency, but also enhances the flowability of the water flow.

[0050] Referring to Figure 6 In one embodiment of the present application, the removable structure 2 comprises a first removable part 23 and a second removable part 24 that are sealedly connected to each other, and the water injection channel and the gas storage chamber 25 are formed between the first removable part 23 and the second removable part 24.

[0051] It can be understood that in the present embodiment, a continuous water injection channel can be formed between the first removable part 23 and the second removable part 24, and the water injection channel allows liquid to pass through and be evenly distributed to the area that needs to be injected with water, thereby improving the water injection efficiency and uniformity.

[0052] It can be understood that a gas storage chamber 25 is also formed between the first removable part 23 and the second removable part 24 in the embodiment. Since the gas storage chamber 25 and the water injection channel are in communication, during water injection, the escaping gas in the internal cavity 11 of the plate body 1 can be discharged into the gas storage chamber 25 through the water injection channel, thereby providing storage space for the escaping gas after being discharged through the first water injection port 12. In addition, since the channel 21 and the water injection device are sealingly connected during water injection, the provision of the gas storage chamber 25 avoids the problems of difficulty in water injection and reduction in water injection efficiency caused by the inability of the internal gas pressure of the vapor chamber to be discharged.

[0053] Referring to Figures 3-4 In a specific embodiment of the present application, the water injection channel includes a first water injection groove 231 provided on the first removable part 23 and a second water injection groove 241 provided on the second removable part 24.

[0054] It can be understood that the first water injection groove 231 and the second water injection groove 241 in the embodiment are preferably circular arc grooves, and the embodiment does not make specific limitations thereon. Any groove shape that can realize water injection operation or access to a water injection device can be provided.

[0055] It can be understood that, in the embodiment, the first water injection groove 231 is provided on the first cover plate and the second water injection groove 241 is provided on the second cover plate, thereby forming a continuous water injection channel. The water injection channel allows liquid to pass through and be uniformly distributed to the area requiring water injection, thereby improving water injection efficiency and uniformity. In addition, since the water injection grooves are provided separately, they can be customized for different removable part materials and shapes to adapt to different application requirements.

[0056] In a specific embodiment of the present application, in the water injection direction of the water injection channel, the length of the first water injection groove 231 is longer than the length of the second water injection groove 241, and the first water injection groove 231 is in communication with the first water injection port 12.

[0057] It can be understood that, in the embodiment, the first water injection groove 231 and the second water injection groove 241 combine to form a water injection channel. The first water injection groove 231 is in communication with the first water injection port 12, thereby realizing liquid injection of the internal cavity 11 of the vapor chamber by the water injection device. The second water injection groove 241 is not in communication with the first water injection port 12, thereby allowing the escaping gas in the internal cavity 11 to be discharged into the gas storage chamber 25 through the second groove during water injection, providing a gas discharge channel for the escaping gas after being discharged through the first water injection port 12, and being discharged into the gas storage chamber 25. Since the second water injection port is sealingly connected with the water injection device during water injection, the escaping gas is stored in the gas storage chamber 25.

[0058] Referring to Figure 6In an embodiment of the present application, the air chamber 25 comprises a first air storage groove 232 arranged in the first removable part 23 and a second air storage groove 242 arranged in the second removable part 24.

[0059] In an embodiment of the present application, the air chamber 25 is an oval cavity or a rhombic cavity.

[0060] It can be understood that the first air storage groove 232 and the second air storage groove 242 combine to form the air chamber 25. When water is injected into the internal cavity 11 of the plate body 1 through the water injection channel, the water flow passes through the first channel 21, the air chamber 25 and the second channel 22 in sequence. When the water flow passes through the air chamber 25, the internal diameter of the air chamber 25 first gradually increases and then gradually decreases. When the water flow enters the air chamber 25, the water flow speed slows down with the increase of the diameter of the cavity, resulting in a local pressure drop and forming a low-pressure area. Subsequently, when the water flow passes through the part with gradually decreasing diameter, the water flow speed increases, resulting in a local high-pressure area. Therefore, the oval or rhombic cavity design can produce a pressure change effect of first decreasing and then increasing when the water flow passes through, which can optimize the dynamic characteristics of the water flow and improve the efficiency of water injection.

[0061] In an embodiment of the present application, the internal cavity 11 is provided with a heat dissipation fin 3. The heat dissipation fin 3 is, for example, a copper mesh. Of course, the heat dissipation fin 3 can also be replaced by a liquid absorption chip.

[0062] Specifically, the heat dissipation fin 3 in the embodiment can effectively exchange heat with the internal water, thereby improving the stability and service life of the device.

[0063] On the other hand, the present application also provides a processing method of a vapor chamber, comprising:

[0064] S1, fixing the plate body 1 and sealingly connecting a water injection nozzle to the water injection channel of the removable structure 2 at the water inlet end, and the water injection nozzle is connected to a water source;

[0065] S2, the water flow in S1 passes through the air chamber 25 of the removable structure 2 and enters the first water injection port 12 of the plate body 1 from the water outlet end of the water injection channel, and finally a certain amount of water is injected into the internal cavity 11 of the plate body 1; during the water injection process, the gas in the internal cavity 11 is discharged to the air chamber 25 through the first water injection port 12 and the water injection channel, and the air storage capacity of the air chamber 25 is equal to or greater than the exhaust capacity after the internal cavity 11 is injected with water, that is, the water injection is completed.

[0066] S3, closing the first water injection port 12 in S2, that is, obtaining a vapor chamber.

[0067] S4, removing the removable structure 2 in S3.

[0068] Specifically, in the above S4, the reserved end after the removal of the removable structure 2 is removed to be flush with the corresponding side edge of the plate body 1, so as to avoid the convexity of the removable structure 2 from affecting the installation and fixation of the uniform heat plate.

[0069] In some embodiments of the present application, before the above S1, further comprising:

[0070] S0, plate body 1 forming process, the specific processing steps are as follows:

[0071] The first cover plate and the first removable part 23 with the first internal sub-cavity, and the second cover plate and the second removable part 24 with the second internal sub-cavity are punched out by the punching process. When the edges of the first cover plate and the second cover plate, and the edges of the first removable part 23 and the second removable part 24 are sealed and connected, the first internal sub-cavity and the second internal sub-cavity form the internal cavity 11, and the first removable part 23 and the second removable part 24 form the water injection channel and the gas storage chamber 25, and the first water injection port 12 can be arranged on the first cover plate or the second cover plate.

[0072] That is, the first cover plate and the first removable part 23 are formed by punching at one time, and the first internal sub-cavity, the first gas storage groove 232 and the first water injection groove 231 are formed at one time, which can improve the processing efficiency, and at the same time, can avoid the residual metal scraps in the plate body due to the secondary mechanical processing (such as the metal scraps caused by the opening of the exhaust hole, etc.).

[0073] Similarly, the second cover plate and the second removable part 24 also have the above advantages, which will not be described here.

[0074] Secondly, by the punching method, the consistency of product quality can be ensured to ensure the sealing performance and product quality reliability after mutual assembly.

[0075] It can be understood that the processing method of the uniform heat plate in the embodiment has the same beneficial effects as the above uniform heat plate, which will not be described here.
