Description

Technical Field

[0001] This utility model belongs to the field of welding technology for heat pipe heat transfer bodies in power supplies, and particularly relates to a welding device for heat pipe heat transfer bodies in power supplies. Background Technology

[0002] With the rapid development of the marine vessel industry, the performance of ship propulsion systems is constantly improving, and the number of power modules is also increasing accordingly. In order to optimize the hull structure and improve space utilization, the space for power modules has been significantly reduced. Under these circumstances, traditional heat dissipation unit designs can no longer meet the requirements, and heat dissipation units must be designed with irregular structures to adapt to the limited space of the hull.

[0003] The heat dissipation unit mainly includes a substrate, heat pipes or water pipes, and fins. Heat pipes or water pipes are welded onto the substrate, and fins are used to dissipate heat from the heat pipes or water pipes. To reduce the space required for power module placement, the heat pipes or water pipes, which were originally mounted on the substrate plane, are now extended from the side or near the side of the substrate. The welding holes on the substrate are located on the side, and the heat pipes or water pipes need to be inserted into these holes for welding. For example, patent application number CN201510253370.0 discloses a heat pipe heat dissipation module for marine power supplies. Patent application number CN202420286853.5 discloses a heat pipe heat dissipation device for marine power supplies. The welding process for this irregularly shaped heat dissipation unit faces many challenges. General-purpose welding stations, due to their structural and functional limitations, cannot meet the welding requirements of irregularly shaped heat dissipation units. Specifically, general-purpose welding stations have the following problems:

[0004] Soldering method not applicable: General-purpose soldering stations typically use a horizontal soldering method, while the heat pipes of irregularly shaped heat sinks extend from one side of the heat sink unit, requiring side soldering to ensure that the solder can fully fill the solder holes on the substrate. General-purpose soldering stations cannot provide this specific soldering angle and position.

[0005] Difficulty in welding positioning: The heat dissipation unit has a complex shape, and the general welding station lacks an effective positioning device, making it difficult to ensure the stability and consistency of the heat dissipation unit during the welding process, which can easily lead to welding defects.

[0006] Low welding efficiency: General-purpose welding stations are typically designed for single-station operation, which cannot meet the needs of simultaneous welding at multiple stations. In the production of marine power modules, the number of heat dissipation units to be welded is large, and the welding efficiency of a single station is insufficient to meet production demands.

[0007] Lack of dedicated clamping device: During the welding process, a certain amount of pressure needs to be applied to the heat dissipation unit to ensure that the welding heat can be evenly conducted to all parts of the heat dissipation unit. General welding stations usually do not have a dedicated clamping device and cannot meet this requirement.

[0008] In summary, existing general-purpose welding stations cannot meet the welding requirements of irregularly shaped heat dissipation units for marine power modules. Specialized welding equipment is needed to solve these problems, improve welding quality and efficiency, and ensure the heat dissipation performance and reliability of marine power modules. Summary of the Invention

[0009] The purpose of this invention is to provide a welding device for heat pipe heat transfer bodies in power supplies, thereby solving the problem of welding heat pipes to substrates in irregularly shaped heat dissipation units.

[0010] To achieve the above objectives, this utility model employs the following technical solution:

[0011] A welding device for a heat transfer body of a power supply heat pipe includes a frame and at least one set of welding units connected to the frame. Each welding unit includes an electric heating plate, a cylinder, and a pressure plate. The electric heating plate is vertically fixed on the frame, the cylinder is fixedly connected to the frame, the cylinder is connected to the pressure plate, and the pressure plate is arranged opposite to the electric heating plate.

[0012] It also includes cast iron plates and insulation plates. The cast iron plates are connected to the frame, and the insulation plates are fixed between the electric heating plates and the cast iron plates.

[0013] The cast iron plate, insulation plate, and electric heating plate are fixedly connected to the frame by bolts.

[0014] A positioning plate is fixedly connected to the frame, and the positioning plate is set on the bottom and side surfaces of the cast iron plate.

[0015] The pressure plate is fixedly connected to the insulating asbestos board, and the piston of the cylinder is connected to the pressure plate through the insulating asbestos board.

[0016] The insulation board is an asbestos board.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model has a reasonable structure and adopts a vertical welding method, which can adapt to the structural characteristics of the heat pipe of the heat dissipation unit extending from the side, ensuring that the solder can be fully filled into the welding hole of the heat dissipation substrate, thereby effectively solving the welding problem of irregular heat dissipation units.

[0019] 2. The combination of the electric heating plate, the heat insulation plate, and the cast iron plate in this utility model not only provides stable welding heat, but also effectively prevents the electric heating plate from deforming due to heat, thus ensuring the stability and reliability of the welding process.

[0020] 3. This utility model can use multiple welding units to meet the needs of welding multiple heat dissipation units at the same time. This multi-station design significantly improves welding efficiency and meets the needs of large-scale production.

[0021] 4. This invention utilizes a cylinder to provide stable clamping force, ensuring the heat dissipation unit is tightly attached to the electric heating plate. This guarantees that welding heat is evenly conducted to all parts of the heat dissipation unit, thereby improving welding consistency and quality. Furthermore, using a cylinder to provide clamping force significantly saves operation time and labor intensity compared to traditional manual clamping methods. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings. However, it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0025] See Figure 1 A welding device for a heat transfer body of a power supply heat pipe includes a frame 1 and at least one welding unit. The welding unit is connected to the frame 1. The welding unit includes an electric heating plate 2, a cylinder 3, and a pressure plate 4. The electric heating plate 2 is vertically fixed on the frame 1. The cylinder 3 is fixedly connected to the frame 1 and connected to the pressure plate 4. The pressure plate 4 is arranged opposite to the electric heating plate 2.

[0026] The welding device for the heat transfer body of the power supply heat pipe also includes a cast iron plate 5 and an insulation plate 6. The cast iron plate 5 is connected to the frame 1, and the insulation plate 6 is fixed between the electric heating plate 2 and the cast iron plate 5. The cast iron plate 5, the insulation plate 6, and the electric heating plate 2 are fixedly connected to the frame 1 by bolts. The insulation plate 6 is an asbestos board.

[0027] A positioning plate 7 is fixedly connected to the frame 1. The positioning plate 7 is set on the bottom and side surfaces of the cast iron plate 5 and is used to position the base plate. The pressure plate 4 is fixedly connected to the insulating asbestos board. The piston of the cylinder 3 is connected to the pressure plate 4 through the insulating asbestos board. The insulating asbestos board is used to insulate heat and prevent the cylinder 3 from operating at high temperatures.

[0028] Example

[0029] The welding apparatus for the heat transfer element of the power supply heat pipe includes a frame 1 and four welding units connected side-by-side on the frame 1. An electric heating plate 2 is designed according to the size of the heat dissipation unit's substrate surface to provide welding heat. An HT200 cast iron plate 5 is then installed on the back of the heating plate, with an asbestos board placed between them to insulate against heat. The electric heating plate 2, the asbestos board, and the HT200 cast iron plate 5 are all bolted to the upright plate of the frame 1.

[0030] The heat pipes are soldered with the protruding side facing upwards to ensure the solder fully fills the solder holes in the substrate. Positioning plates 7 are installed on the bottom and sides of the cast iron plate 5, extending beyond the heating plate surface. These plates are used for vertical placement and side positioning of the substrate, completing the positioning process. A movable pressure plate 4 is installed opposite the heating plate, with a pneumatic system providing clamping force. A cylinder 3 is fixed to the frame 1. The pressure plate 4 and the insulating asbestos board are connected by bolts, with the cylinder 3 connected to the insulating asbestos board. The pressure plate 4 is used to press the substrate, and the insulating asbestos board is used to insulate against heat, preventing the cylinder 3 from being affected by heat and affecting its seal. The cylinder 3 is connected to a pneumatic circuit to provide clamping force. The pressure plate 4 corresponds to the electric heating plate 2. A temperature sensor can be installed on the electric heating plate 2 to detect the heating temperature.

[0031] The cylinders 3 of the four welding units are supplied with air by a separate pneumatic system, and the electric heating plates 2 are also supplied with power separately, so they can work simultaneously and alternately without interfering with each other.

[0032] The solder melting temperature is 185℃. During soldering, the substrate is positioned against the positioning plate 7. Under the action of the cylinder 3, the substrate is pressed between the pressure plate 4 and the electric heating plate 2. The electric heating plate 2 heats the substrate to 185℃. After the solder in the soldering hole of the substrate melts, the heat pipe is placed at the position to be soldered. Heating is stopped. When the temperature drops to 60℃, the piston rod of the cylinder 3 retracts, the substrate is removed, and the soldering of the heat pipe is completed.

[0033] The new welding device effectively solves the shortcomings of existing general welding stations in welding irregular heat dissipation units by optimizing welding methods, improving welding efficiency, ensuring welding consistency, and precisely controlling temperature. It significantly improves the welding quality and production efficiency of heat dissipation devices for marine power modules.
