Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of welding technology, and in particular to a welding method and a product processed thereby. Background Art
[0002] During a welding operation, solder paste is typically applied to the end of a first component, which is then secured to a second component via soldering to form a finished product. However, this traditional welding method presents several challenges. First, controlling the amount of solder paste used is crucial. Using too little solder paste can easily lead to poor soldering, compromising product quality and reliability. Conversely, using too much solder paste can cause excess solder paste to leak out, affecting the product's appearance and potentially creating safety hazards such as short circuits. Second, excessive solder paste can be drawn into the gap between the first and second components. In this case, thermal expansion and contraction can easily cause deformation at the weld joint, impacting not only the product's appearance but also its functionality and lifespan. Furthermore, traditional welding methods require high operator skill, requiring precise control of solder paste application, which increases the complexity of the production process and the potential for human error. Furthermore, this method's low level of automation makes it difficult to meet the demands of large-scale production. Finally, traditional welding methods are not environmentally friendly or energy-efficient. Excessive solder paste waste not only increases production costs but also potentially causes unnecessary environmental pollution. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them.

[0031] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions of this disclosure can be achieved. This is not a limitation herein.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.
[0033] The following describes in detail the various embodiments of the present application in conjunction with the accompanying drawings.
[0034] Please also refer to Figure 1 and Figure 2 This embodiment provides a welding method, which can be applied to devices such as a vapor chamber, a heat sink, or a heat exchanger, and is not limited here. The welding method includes the following steps:
[0035] S1 , providing a first component 11 to be soldered, opening a slot 111 on the first component 11 , and placing solder 13 in the slot 111 .
[0036] S2 , providing a second component 12 to be soldered, and pre-fixing the first component 11 with solder 13 placed thereon to the second component 12 .
[0037] S3, providing a heating furnace, placing the second component 12 pre-fixed with the first component 11 into the heating furnace, and melting the solder 13 in the first component 11 by the heating furnace, so that the first component 11 is welded and fixed to the second component 12 to form a product. For example, the solder 13 can be brazing material.
[0038] In the above-mentioned welding method, a first component 11 to be welded is provided, a slot 111 is opened on the first component 11, and solder 13 is placed in the slot 111; a second component 12 to be welded is provided, and the first component 11 with the solder 13 is pre-fixed to the second component 12; a heating furnace is provided, and the second component 12 with the first component 11 pre-fixed is put into the heating furnace, and the heating furnace melts the solder 13 in the first component 11 so that the first component 11 is welded and fixed to the second component 12 to form a product; in this way, by opening the slot 111 on the first component 11 and placing the solder 13 in the slot 111, the amount of solder 13 can be accurately controlled to avoid the problem of too much or too little solder 13, thereby improving the welding quality and reducing the waste of solder 13. At the same time, the first component 11 is pre-fixed to the second component 12 and then welded by the heating furnace, which simplifies the operation process, reduces the requirements for the operator's skills, and improves production efficiency. The above-mentioned welding method has the advantages of improving welding quality, reducing the waste of solder 13, simplifying the operation process, and improving production efficiency.
[0039] See also Figure 3 In some embodiments, the slot 111 penetrates the first component 11 , and the heating furnace melts the solder 13 in the first component 11 so that the two ends of the first component 11 are welded and fixed to the top 121 and the bottom 122 respectively.
[0040] Thus, by providing slots 111 extending through first component 11, the solder 13 is ensured to be fully melted and evenly distributed during the heating process, thereby solving the problem of how to melt the solder 13 in the first component 11 using a heating furnace and securely weld the two ends of the first component 11 to the top 121 and bottom 122, respectively. The use of a heating furnace melts the solder 13 within the first component 11, thereby evenly distributing the solder 13 at the two ends of the first component 11, and ultimately securing the two ends of the first component 11 to the top 121 and bottom 122, respectively.
[0041] Specifically, the through-hole design of slots 111 effectively improves the uniformity of heating of the solder 13, preventing local overheating or insufficient melting of the solder 13 during the heating process. The first component 11 is heated in a furnace, allowing the solder 13 to fully melt and evenly distribute within the slots 111, thereby ensuring that the ends of the first component 11 are securely soldered to the top 121 and bottom 122.
[0042] Preferably, the cross-sectional shapes of the first component 11 and the slot 111 are both circular, wherein the ratio between the outer diameter and the inner diameter of the first component 11 is 2-3. For example, when the outer diameter of the first component 11 is 3 mm, the aperture of the slot 111 is 1-1.5 mm, so that the solder 13 can be placed into the slot 111 while ensuring the supporting strength of the first component 11.
[0043] It can be understood that when the ratio between the outer diameter and the inner diameter of the first component 11 is less than 2, the slot 111 of the first component 11 is too large, affecting the supporting strength of the first component 11. When the ratio between the outer diameter and the inner diameter of the first component 11 is greater than 3, the aperture of the first component 11 is too small, resulting in a smaller space, which is not conducive to the placement of the solder 13.
[0044] See also Figure 2 In some embodiments, a top portion 121 and a bottom portion 122 to be welded are provided, and the first component 11 is first clamped between the top portion 121 and the bottom portion 122, and then the top portion 121 is clamped to the bottom portion 122, so that the first component 11 is pre-fixed between the top portion 121 and the bottom portion 122. The top portion 121 is clamped to the bottom portion 122 to form the second component 12. For example, the top portion 121 and the bottom portion 122 may be made of copper, aluminum, or a copper-aluminum alloy.
[0045] In this way, by providing the top 121 and the bottom 122, the first component 11 is clamped between the top 121 and the bottom 122, and the top 121 is clamped to the bottom 122, thereby achieving pre-fixation of the first component 11, and the first component 11 can be stably fixed on the second component 12 before welding by clamping, thereby improving the welding quality and product reliability.
[0046] Furthermore, a variety of snap-fit structures may be used between the top 121 and the bottom 122. For example, a snap-fit groove and a snap-fit buckle may be provided on the contact surface between the top 121 and the bottom 122, and snap-fit fixation may be achieved through the cooperation of the snap-fit groove and the snap-fit buckle.
[0047] Furthermore, a sealing member may be provided on the contact surfaces of the top portion 121 and the bottom portion 122. The sealing member is provided in an annular manner along the contact surfaces to provide a travel seal when the top portion 121 and the bottom portion 122 are secured. For example, the sealing member may be a rubber sealing ring; alternatively, the gap between the contact surfaces of the top portion 121 and the bottom portion 122 may be sealed by welding.
[0048] Furthermore, there are multiple first components 11 , which are arranged at intervals, and each first component 11 filled with solder 13 is pre-fixed between the top 121 and the bottom 122 .
[0049] Furthermore, a carrying jig is provided, and the first component 11 is first positioned on the carrying jig, and then the bottom 122 is covered and clamped on the carrying jig so that the first component 11 is clamped between the bottom 122 and the carrying jig; the carrying jig and the bottom 122 clamping the first component 11 are turned upside down so that the bottom 122 faces downward and the carrying jig faces upward; the carrying jig is moved away from the bottom 122, and solder 13 is placed into the slot 111 of the first component 11, and the top 121 is covered and clamped on the bottom 122, so that the first component 11 is clamped between the top 121 and the bottom 122.
[0050] In this way, through these steps, the solder 13 can be effectively fixed and placed during the welding process, ensuring that the position of the solder 13 is accurate, thereby improving the welding quality and avoiding the problem of too much or too little solder 13.
[0051] Specifically, first, the first component 11 is positioned on the carrier jig, and the bottom 122 is placed on and clamped on the carrier jig so that the first component 11 is clamped between the bottom 122 and the carrier jig. This step ensures that the first component 11 can be stably fixed in the specified position during the welding process. Then, the carrier jig and the bottom 122 holding the first component 11 are turned upside down so that the bottom 122 faces downward and the carrier jig faces upward. This step facilitates subsequent operations and ensures that the solder 13 can be accurately placed in the slot 111 of the first component 11. Next, the carrier jig is moved away from the bottom 122, and the solder 13 is placed into the slot 111 of the first component 11. The top 121 is placed on and clamped on the bottom 122 so that the first component 11 is clamped between the top 121 and the bottom 122. In this way, the solder 13 can be accurately placed in the slot 111 of the first component 11, ensuring welding quality.
[0052] See also Figure 2 In some embodiments, a first copper mesh 1212 and a first shell 1211 are provided, and the first copper mesh 1212 is fixed to the first shell 1211 to form a top 121. When the first component 11 is clamped between the top 121 and the bottom 122, one end of the first component 11 is abutted against the first copper mesh 1212.
[0053] In this way, the mesh structure of the first copper mesh 1212 can gather the condensed cooling medium and form a larger condensation area, so that the gaseous cooling medium can be quickly condensed into liquid, thereby improving the condensation effect and increasing the heat dissipation efficiency.
[0054] Furthermore, the first copper mesh 1212 can be fixed by welding, screw connection, or bonding, etc. As a preferred embodiment, the first copper mesh 1212 can be fixed to the first housing 1211 by welding to ensure the firmness and reliability of the connection.
[0055] See also Figure 2 In some embodiments, a second copper mesh 1222 and a second shell 1221 are provided, and the second copper mesh 1222 is fixed to the second shell 1221 to form a bottom 122. When the first component 11 is clamped between the top 121 and the bottom 122, the other end of the first component 11 is abutted against the second copper mesh 1222.
[0056] In this way, by fixing the second copper mesh 1222 on the second shell 1221 and storing the cooling medium through the mesh holes of the second copper mesh 1222, the cooling medium has a larger heating area, so that it can evaporate faster and become gas and diffuse, thereby improving the evaporation efficiency of the cooling medium and further improving the heat dissipation efficiency.
[0057] Preferably, the second copper mesh 1222 can be made of a variety of materials and structures. For example, the mesh size and shape of the copper mesh can be adjusted according to actual needs to optimize the heat dissipation effect.
[0058] In some embodiments, an evaporation tank is opened at the bottom 122 for storing cooling medium. Specifically, the position of the evaporation tank corresponds to the position of the external heat source, and capillary channels are opened on the top 121 and the bottom 122 of the second component 12, so that the capillary channel of the top 121 is connected to the capillary channel of the bottom 122, and the capillary channel of the bottom 122 is connected to the evaporation tank.
[0059] In this way, by arranging an evaporation tank at the bottom 122, a space for storing the cooling medium is provided, and the connection between the capillary channel 121 and the bottom 122 ensures that the cooling medium can effectively flow and distribute during the welding process. At the same time, the evaporation tank can ensure that the cooling medium is effectively stored during the welding process, and the design of the capillary channel ensures that the cooling medium can flow back between the top 121 and the bottom 122 to the evaporation tank and the mesh on the second copper mesh 1222. The mesh of the second copper mesh 1222 disperses the cooling medium, which helps to evaporate quickly. The cooling medium in the evaporation tank and the second copper mesh 1222 evaporates after being heated, and flows to the mesh of the first copper mesh 1212 at the top 121 for aggregation. After aggregation, it flows along the capillary channel to the mesh of the evaporation tank and the second copper mesh 1222, thereby achieving a circulating heat dissipation effect of the product.
[0060] Furthermore, the evaporation tank can be formed by opening a groove at an appropriate position on the bottom 122. The size and shape of the groove can be designed according to the storage requirements of the cooling medium. The capillary channel can be opened on the top 121 and the bottom 122 using micro-machining technology, or it can be indirectly set on the top 121 and the bottom 122 through a capillary plate. The size and spacing of these channels should be able to ensure the effective flow and distribution of the cooling medium.
[0061] Furthermore, the capillary channel may adopt different geometric shapes, such as straight, curved or spiral, to optimize the flow path and efficiency of the cooling medium.
[0062] See also Figure 1 , S4, the welding method further comprises the steps of:
[0063] The second component 12 formed after the top 121 is snapped onto the bottom 122 has a filling cavity inside. Specifically, the filling cavity is formed by the top 121 and the bottom 122. A liquid injection device is provided to fill the cooling medium into the filling cavity of the second component 12 through the liquid injection device.
[0064] Thus, the purpose of filling the filling cavity of the second component 12 with the cooling medium by the liquid injection device is to convert the cooling medium into gas after being heated and fill the second component 12, thereby facilitating rapid heat conduction and diffusion. In this way, the heat diffusion efficiency of the second component 12 is improved.
[0065] Furthermore, the injection equipment can take various forms. For example, manual injection equipment or automatic injection equipment can be used. Manual injection equipment usually includes a syringe or a manual pump, which is simple to operate and suitable for small-scale production. Automatic injection equipment includes an electric pump or a hydraulic pump, which is suitable for large-scale production and can improve injection efficiency.
[0066] Furthermore, a flow control device may be provided in the liquid injection device to precisely control the injection amount of the cooling medium and ensure the consistency of the cooling effect.
[0067] Furthermore, the choice of cooling medium can also be diversified. For example, the cooling medium can be water, ethylene glycol, liquid nitrogen, etc. Different cooling media can be selected according to specific application requirements.
[0068] See also Figure 1 , S5, the welding method further comprises the steps of:
[0069] A negative pressure component is provided, through which air in the filling cavity of the second component 12 is extracted, so that the filling cavity of the second component 12 is in a negative pressure state.
[0070] In this way, by extracting the air inside the second component 12, a negative pressure state is formed in the filling cavity. The negative pressure state can prevent the air from affecting the welding process and ensure the welding quality and effect. At the same time, the negative pressure state helps the filling and flow of the cooling medium, further improving the performance and reliability of the welding product.
[0071] Furthermore, the negative pressure component can be implemented by a vacuum pump or other device capable of generating negative pressure; preferably, the vacuum pump can be connected to the filling cavity in the second component 12 through a pipeline, and the air pressure in the filling cavity in the second component 12 can be adjusted by controlling the working state of the vacuum pump.
[0072] Furthermore, a pressure sensor may be provided in the filling cavity of the second component 12 to monitor the negative pressure state in real time and ensure the working effect of the negative pressure component.
[0073] Furthermore, a plurality of air extraction ports may be provided at different locations within the second component 12 so as to extract air more evenly and ensure a consistent negative pressure state within the entire second component 12 .
[0074] Furthermore, the second component 12 also includes a support body 14, which is received in the filling cavity and fixedly connected between the top 121 and the bottom 122. The support body 14 is used to support the top 121 and the bottom 122 to improve the strength of the second component 12 and reduce the risk of deformation caused by negative pressure.
[0075] In this embodiment, the first housing 1211 , the second housing 1221 , the first copper mesh 1212 , and the second copper mesh 1222 are all cut to obtain standard size specifications.
[0076] This embodiment also discloses a product, which is manufactured using the above-mentioned welding method. The product is not limited to devices such as a temperature homogenizer, a radiator, or a heat exchanger.
[0077] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
