[0025] In order to make the technical means, creation characteristics, purposes and effects realized by the utility model easy to understand, the following further describes the utility model by combining with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, and are not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] The specific embodiments of the utility model are described below by combining with the drawings. Specific embodiment one:

[0028] Reference Figs. 1-6The utility model provides a metal plate welding circulating water cooling anti -variator, including cooler main part 1 and support leg 4, cooler main part 1 is the core structure of whole water cooling variator, provides installation and containing space for inside flow guide pipe, guide floating head 2 etc. Component, it is also the main place of heat exchange simultaneously, bears the circulation flow of cooling liquid and heat exchange process, one side of cooler main part 1 top surface is equipped with cooling liquid inlet pipe 7, one side of cooler main part 1 bottom surface is equipped with cooling liquid outlet pipe 8, and cooling liquid enters the inside of cooler main part 1 from cooling liquid inlet pipe 7, and is contacted with first spiral flow guide pipe 12 and second spiral flow guide pipe 13 in the main part, and heat is passed to cooling liquid through flow guide pipe, and the cooling liquid after heating flows from cooling liquid outlet pipe 8, realizes the carrying out of heat and cooling, according to the demand of heat exchange, cooling liquid continues to circulate in cooler main part 1, guarantees the stable cooling of system, provides stable structural basis for whole water cooling system, ensures that heat exchange process can orderly carry out in its inside, guarantees the normal operation and cooling function realization of whole equipment.

[0029] The first spiral flow guide pipe 12 is arranged at a position close to the center in the cooler body 1, and the second spiral flow guide pipe 13 is arranged at a position close to the inner wall in the cooler body 1. The two ends of the cooler body 1 are connected with the guide floating head 2. The first spiral flow guide pipe 12 and the second spiral flow guide pipe 13 penetrate the surface of the sealing plate 11. The first spiral flow guide pipe 12 is provided with two groups, and the adjacent first spiral flow guide pipes 12 are symmetrically distributed along the center of the installation position. The first spiral flow guide pipe 12 guides the flow of the cooling liquid in the cooler body 1, increases the contact area between the cooling liquid and the internal space of the cooler body 1, and promotes the heat exchange efficiency. The double spiral structure enables the flow guide pipe to have a larger surface area in a limited space, thereby enhancing the heat transfer effect between the cooling liquid and the material to be cooled. The cooling liquid enters the first spiral flow guide pipe 12 from one end, flows in the cooler body 1 along the spiral structure, and in the process, heat is transferred from the surrounding environment to the cooling liquid in the flow guide pipe, causing the temperature of the cooling liquid to rise. Finally, the cooling liquid flows out of the flow guide pipe from the other end, forming a circulating flow path with the cooling liquid in the cooler body 1. Through the special spiral structure, the heat exchange process is optimized, the efficiency and speed of heat transfer are improved, the area occupied by the flow guide pipe in the cooler body 1 is effectively increased, the cooling liquid is facilitated to fully contact the incoming liquid, the contact area is increased, rapid heat exchange is performed, and the circulating water cooling efficiency is improved. The second spiral flow guide pipe 13 in the cooler body 1 is symmetrically distributed along the center of the installation position, and the second spiral flow guide pipe 13 on one side of the cooler body 1 is provided with multiple groups in the horizontal direction. The second spiral flow guide pipe 13 is similar to the first spiral flow guide pipe 12 and is mainly used for guiding the flow of the cooling liquid and promoting heat exchange. The distribution position and number of the second spiral flow guide pipe 13 in the cooler body 1 further optimize the heat exchange effect in the cooler body 1 and improve the overall cooling performance in cooperation with the first spiral flow guide pipe 12. After the cooling liquid enters the second spiral flow guide pipe 13, it flows in the spiral structure, heat is transferred from the outside to the cooling liquid, heat exchange and transfer are realized, and the cooling liquid circulating network in the cooler body 1 is constructed together with the first spiral flow guide pipe 12. Different distribution positions and numbers enable the cooling liquid to more comprehensively and uniformly exchange heat in the cooler body 1. The symmetric distribution along the center of the installation position and the multiple groups on one side cooperate with the first spiral flow guide pipe 12 to comprehensively improve the heat exchange efficiency in the cooler body 1, making the cooling effect more uniform and efficient.

[0030] The guide float head 2 plays a guiding and buffering role in the cooling liquid flow process, and the internal liquid flow guide disc 9 can further guide and disperse the entering cooling liquid, optimizing the contact effect of the cooling liquid with the spiral flow guide pipe. When the cooling liquid flows from the cooler main body 1 into the guide float head 2, it is first affected by the liquid flow guide disc 9 and is scattered by the arc-shaped guide blades 10, changing the flow direction and shape, and then flows out of the guide float head 2 into the next circulation path. As a transition component connecting the cooler main body 1 and the external pipeline, it guides and regulates the flow of cooling liquid, ensuring stable circulation and efficient heat exchange of the cooling liquid in the entire system. The internal liquid flow guide disc 9 guides the liquid, and the entering liquid is scattered under the action of the arc-shaped guide blades 10 on the surface of the liquid flow guide disc 9, increasing the contact area with the first spiral flow guide pipe 12 and the second spiral flow guide pipe 13, and forming a vortex flow of the flowing liquid, further improving the heat exchange efficiency. The guide float head 2 is internally provided with a liquid flow guide disc 9, which is internally provided with a plurality of arc-shaped guide blades 10 arranged in a straight line array. The outer wall of the liquid flow guide disc 9 is threadedly connected with the inner wall of the guide float head 2, and the center position of the arc-shaped guide blade 10 is movably connected with the inner wall of the liquid flow guide disc 9. The liquid flow guide disc 9 is located inside the guide float head 2 and is used to guide and disperse the cooling liquid entering the guide float head 2, change the flow state of the cooling liquid, and make it more fully contact with the spiral flow guide pipe, improving the heat exchange efficiency. When the cooling liquid enters the liquid flow guide disc 9, it is impacted and changes direction due to the action of the arc-shaped guide blades 10, forming a dispersed flow state and increasing the contact opportunity with the spiral flow guide pipe. In combination with the overall flow guiding function of the guide float head 2, the cooling liquid is effectively regulated at the moment of entering, optimizing the flow and heat exchange process of the cooling liquid in the entire cooling system. The entering liquid is scattered under the action of the arc-shaped guide blades 10 on its surface, increasing the contact area with the first spiral flow guide pipe 12 and the second spiral flow guide pipe 13, improving the heat exchange effect, and promoting the efficient operation of the entire water cooling system.

[0031] The arc-shaped material guiding blade 10 is a key component of the liquid guiding disc 9. Through the special arc-shaped structure, the cooling liquid entering the liquid guiding disc 9 is scattered and forms a vortex and other special flow patterns, thereby enhancing the contact effect of the cooling liquid with the spiral flow guide pipe. By virtue of the relative relationship between the arc-shaped shape and the flow direction of the cooling liquid, when the cooling liquid impacts on the arc-shaped material guiding blade 10, the blade generates a lateral force on the cooling liquid, so that the flow direction of the cooling liquid is changed and the cooling liquid is scattered. At the same time, the vortex is formed under the guidance of the blade, the mixing and flow speed of the cooling liquid are increased, and the cooling liquid continues to play a role when passing through the liquid guiding disc 9, so that the flow state of the cooling liquid is constantly changed, the cooling liquid can more fully exchange heat with the spiral flow guide pipe, the flowing liquid is formed into a vortex and flows rapidly in the liquid guiding disc 9, the contact area with the spiral flow guide pipe is increased, and thus the circulating water cooling efficiency is improved and the cooling performance of the entire water-cooled transformer is improved.

[0032] The cooler body 1 is provided with a sealing flange 3 at both ends, and the sealing flange 3 is connected with the end of the guide floating head 2. The sealing flange 3 connects the cooler body 1 and the guide floating head 2, plays a sealing and fixing role, ensures the tightness of the connection between the two, prevents the cooling liquid from leaking at the connection, and at the same time provides protection for the structural stability of the entire device. The support feet 4 are bolted at the bottom of the cooler body 1, support the entire water-cooled transformer device, so that it can be stably placed on the working plane, bear the weight of the device, and keep the balance and stability of the device.

[0033] The end of the guide floating head 2 at one end of the cooler body 1 is provided with a floating head liquid inlet pipe 5, and the end of the guide floating head 2 away from the floating head liquid inlet pipe 5 is provided with a floating head liquid outlet pipe 6. The floating head liquid inlet pipe 5 provides a cooling liquid input channel for the guide floating head 2, introduces the cooling liquid in the cooler body 1 into the guide floating head 2, so that the cooling liquid is guided and heat exchanged in the guide floating head 2. The floating head liquid outlet pipe 6 discharges the cooling liquid after the guiding and heat exchange optimization in the guide floating head 2, so that the cooling liquid can continue to flow in the cooler body 1 or the entire cooling circulation system to complete the subsequent heat exchange and circulation process.

[0039] Cooling operation in the welding process

[0040] Heat exchange process: in the process of sheet metal welding, the welding site will produce a large amount of heat. These heat is transferred to the cooling channel of the welding equipment, the cooling liquid absorbs heat when flowing through these channels, then, the cooling liquid after heating flows into the cooler body 1 of the water-cooled transformer through the pipeline. In the cooler body 1, the cooling liquid flows in the first spiral guide pipe 12 and the second spiral guide pipe 13, and the heat is dissipated by heat exchange with the external environment of the cooler body 1, which is usually air. The cooling liquid changes the flow state in the guide floating head 2 by the action of the liquid guide disc 9 and the arc-shaped guide blade 10, further optimizes the contact with the guide pipe, and enhances the heat exchange effect, and then flows out of the guide floating head 2, continues to circulate in the system, so as to realize the continuous cooling of the sheet metal welding equipment.

[0041] Temperature control: through the temperature sensor installed in the welding equipment and the water-cooled transformer, the temperature of the cooling liquid and the temperature of the key parts of the welding equipment are monitored in real time. If the temperature is too high, the cooling effect can be enhanced by adjusting the flow of the cooling liquid. For example, increase the circulating speed of the circulating pump or adjust the opening of the valve on the pipeline to increase the circulating speed of the cooling liquid. At the same time, according to the temperature feedback, the welding process parameters such as welding current, welding speed, etc. can also be adjusted appropriately to control the heat generation in the welding process.
