Description

Technical Field

[0001] The utility model relates to the technical field of arc welding machines, in particular to a low-power manual arc welding machine. Background Art

[0002] In traditional manual arc welding machines, heat dissipation design primarily relies on natural convection or air cooling. Natural convection dissipates internal heat to the surrounding environment through the heat sink of the welding machine casing. While its structure is relatively simple, its heat dissipation efficiency is low, making it difficult to effectively control the temperature of the welding machine, especially during high-intensity continuous operation. Air cooling, on the other hand, uses an electric fan to force air flow, increasing the heat dissipation surface area and thus accelerating heat dissipation. However, this type of air-cooling structure generally requires a larger fan motor, resulting in increased power consumption. Furthermore, the operation of the electric fan generates noise and has a limited service life. Especially in harsh environments, the fan is easily damaged by dust, iron filings, and other factors, increasing maintenance costs.

[0003] Although these traditional heat dissipation methods can alleviate the problem of heat accumulation inside the welding machine to a certain extent, there are still some shortcomings. First, natural convection heat dissipation is difficult to meet the temperature control requirements of long-term, high-load operations due to its limited efficiency. Secondly, although air-cooled heat dissipation can improve heat dissipation efficiency, the fan consumes a lot of energy and is not suitable for use in low-power welding machines. In addition, the air-cooled heat dissipation structure is prone to fan failure or air inlet blockage, resulting in a decrease in heat dissipation performance and even causing the welding machine to overheat. In view of this, research and improvement are carried out on the existing problems, and a low-power manual arc welding machine is provided to solve the current problems. The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Utility Model Content

[0004] The utility model aims to solve the technical problems existing in the prior art or related technologies.

[0005] A low-power manual arc welding machine comprises a welding machine body, an oil cooling assembly, and an active heat dissipation assembly. The oil cooling assembly is fixedly mounted on one side of the welding machine body, and several active heat dissipation assemblies are symmetrically arranged on the upper and lower sides of the oil cooling assembly. A control panel is provided on one side of the welding machine body. The oil cooling assembly comprises a fixing base, a circulating oil box, a heat dissipation pipe, a heat dissipation fin, and a heat conduction block fixed to the interior of the welding machine body. The heat conduction block is adhered to the surface of a high-voltage coil on the surface of the welding machine body. The circulating oil box is symmetrically arranged on both sides of the welding machine body and communicates with the interior of the heat conduction block via a pipe. The heat dissipation pipes and heat dissipation fins are arranged in a plurality of numbers and are alternately arranged inside the fixing base. The active heat dissipation assembly comprises a piezoelectric ceramic vibrating element and a metal film fixed to the output end of the piezoelectric ceramic vibrating element. The heat dissipation pipes and heat dissipation fins are provided inside the heat dissipation duct for the movement of the metal film. By adopting the above technical solution, the structure can form an effective cooling oil circulation path, and the micro-vibration of the piezoelectric ceramic vibrating element drives air flow, effectively improving heat dissipation efficiency, ensuring low power consumption and stable operation of the welding machine.

[0006] In a preferred example, the present invention can be further configured as follows: a plurality of the heat dissipation pipes are arranged parallel to each other, and the two ends of the heat dissipation pipes are respectively connected to the interior of the circulating oil boxes on both sides; the heat dissipation pipes, heat dissipation fins and heat conduction blocks are all metal components. By adopting the above technical solution, the metal material design of the heat dissipation pipes, heat dissipation fins and heat conduction blocks can significantly improve the heat conduction efficiency, so that the cooling oil can quickly take away the heat during the circulation process, thereby improving the heat dissipation effect and extending the service life of the welding machine.

[0007] In a preferred embodiment, the present invention can be further configured such that the heat dissipating fins are corrugated, and the surfaces of the heat dissipating fins are welded to the surface of the heat dissipating tube. By adopting this technical solution, the corrugated heat dissipating fins provide a larger surface area, which helps to increase the heat dissipation effect. The corrugated structure also enhances the welding strength, ensuring that good heat dissipation performance is maintained during long-term use.

[0008] In a preferred embodiment, the present invention can be further configured such that a circulating pump for driving the cooling oil is installed inside the circulating oil box and the heat sink fins. The circulating pump is used to circulate the cooling oil within the circulating oil box, the heat sink pipe, and the heat transfer block. By adopting this technical solution, the circulating pump drives the cooling oil to circulate within the system, ensuring that the cooling oil continuously removes heat from within the welder, achieving effective circulating cooling and preventing performance degradation caused by localized high temperatures.

[0009] In a preferred embodiment, this invention can be further configured as follows: the piezoelectric ceramic vibrating element is used to generate mechanical vibrations, vibrating slightly when powered through the inverse piezoelectric effect; the metal film is connected to the piezoelectric ceramic vibrating element to transmit the vibrations to the surrounding air, thereby generating air flow. By adopting this technical solution, the micro-vibration of the piezoelectric ceramic vibrating element can guide air flow, enhancing the heat dissipation effect around the heat sink fins, achieving active heat dissipation while requiring only a small amount of power, making it suitable for low-power welding applications.

[0010] In a preferred embodiment, the present invention can be further configured such that the vibration frequency of the piezoelectric ceramic vibrating element is adjustable to accommodate varying heat dissipation requirements. By employing this technical solution, the frequency-adjustable piezoelectric ceramic vibrating element can adjust its vibration intensity based on the heat dissipation requirements of the welder, increasing the vibration frequency at high temperatures to promote heat dissipation and reducing the vibration frequency at low temperatures to conserve energy, thereby enhancing the system's adaptability and energy-saving effects.

[0011] The beneficial effects achieved by the utility model are:

[0012] 1. This utility model effectively reduces the internal temperature of the welding machine by combining an oil cooling assembly with an active heat dissipation assembly. The design of the circulating oil box, heat pipe, and heat dissipation fins in the oil cooling assembly allows the cooling oil to circulate within the welding machine, transferring heat to the external heat sink and accelerating heat dissipation, thereby improving the durability and stability of the welding machine.

[0013] 2. In this utility model, by adopting an active heat dissipation design of piezoelectric ceramic vibration elements and metal film, the inverse piezoelectric effect is used to generate micro-vibrations to promote air flow. The piezoelectric ceramic material only requires a small amount of electrical energy to generate effective vibrations and does not need to maintain the operation of a high-power motor like a fan. Therefore, the overall energy consumption is extremely low, and power consumption is reduced while ensuring heat dissipation efficiency, which is suitable for the use requirements of low-power welding machines.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0022] The following is combined with Figures 1-4 Some embodiments of the present invention provide a low-power manual arc welding machine. Example 1

[0023] In this embodiment, a low-power manual arc welding machine includes a welding machine body 100, an oil cooling assembly 200, and an active heat dissipation assembly 300. The oil cooling assembly 200 is fixedly mounted on one side of the welding machine body 100, and several active heat dissipation assemblies 300 are symmetrically arranged on the upper and lower sides of the oil cooling assembly 200 to further optimize the heat dissipation effect. A control panel 110 is provided on one side of the welding machine body 100 to facilitate user operation and control. The oil cooling assembly 200 includes a fixing base 210, a circulating oil box 220, a heat dissipation pipe 230, heat dissipation fins 240, and a heat conduction block 250 fixed to the interior of the welding machine body 100. The heat conduction block 250 is adhered to the surface of the high-voltage coil on the surface of the welding machine body 100 to ensure that heat can be quickly transferred to the outside. The circulating oil box 220 is symmetrically arranged on both sides of the welding machine body 100 and is connected to the interior of the heat conduction block 250 via a pipeline to achieve the circulation of cooling oil. The heat pipes 230 and fins 240 are arranged alternately inside the mounting base 210 to increase the heat dissipation area. The active heat dissipation assembly 300 includes a piezoelectric ceramic vibrating element 310 and a metal film 320 fixed to the output end of the piezoelectric ceramic vibrating element 310. The metal film 320 transmits vibrations to the surrounding air, promoting air flow and enhancing heat dissipation efficiency. A heat dissipation air cavity 231 is provided inside the heat pipes 230 and fins 240 to accommodate the movement of the metal film 320 and ensure stable vibration transmission.

[0024] In this structure, the oil cooling assembly 200 forms a complete oil cooling circulation system through the circulating oil box 220, heat pipe 230, and heat dissipation fins 240. The circulating oil box 220 is an oil tank containing cooling oil. A circulating pump propels the oil through the circulating oil box 220, heat pipe 230, and heat conduction block 250, effectively transferring internal heat to the outside. The active heat dissipation assembly 300 generates micro-vibrations through the piezoelectric ceramic vibrating element 310, and the metal film 320 transmits the vibrations to the surrounding air, creating an active heat dissipation function. With this structure, the entire welder can maintain a low temperature during long-term use, extending its service life. Example 2

[0025] In this embodiment, the structure of Example 1 is further optimized and improved, including the addition of a corrugated design for the heat sink fins and an adjustable vibration frequency function to accommodate the heat dissipation requirements under different operating conditions. Consistent with Example 1, the welding machine body 100, oil cooling assembly 200, and active heat dissipation assembly 300 constitute the main structure of this welding machine. The heat pipes 230 and heat sink fins 240 within the oil cooling assembly 200 are heat pipes and corrugated heat sink fins, respectively, arranged alternately within the fixing base 210 to increase the heat transfer area. The active heat dissipation assembly 300 generates mechanical vibrations through a piezoelectric ceramic vibrating element 310, with an adjustable vibration frequency, to improve heat dissipation efficiency in high-temperature environments.

[0026] In this embodiment, several heat pipes 230 are arranged parallel to each other, each connected to the interior of the circulating oil box 220 at both ends, ensuring smooth circulation of cooling oil throughout the cooling system. The cooling fins 240 are corrugated sheets with a larger surface area and are welded to the outer surface of the heat pipes 230, effectively enhancing heat dissipation. The circulating oil continuously flows through the circulating oil box 220, heat pipes 230, and heat conductive blocks 250. Thanks to the use of heat conductive blocks 250, heat is quickly transferred to the cooling fins and dissipated into the air.

[0027] Furthermore, by incorporating a vibration frequency control device into the piezoelectric ceramic vibrating element 310, the vibration frequency is adjusted based on actual temperature requirements, thereby varying the air flow rate and achieving energy savings and efficient heat dissipation. At higher temperatures, the vibration frequency is increased to accelerate air circulation; at lower temperatures, the frequency is reduced to reduce energy consumption. This improvement significantly improves the heat dissipation performance of the welder while maintaining low power consumption, ensuring stable operation and efficient heat dissipation.

[0028] The working principle and use process of this utility model:

[0029] The circulating oil box 220 starts working, pushing the cooling oil to circulate in the oil cooling assembly 200. After the cooling oil absorbs the heat inside the welder through the heat conductive block 250, it enters the heat dissipation pipe 230 for heat dissipation. The piezoelectric ceramic vibration element 310 begins to vibrate slightly, driving the metal film 320 to form air flow, which assists in heat dissipation. The operator can adjust the vibration frequency of the piezoelectric ceramic vibration element 310 through the control panel 110 according to the temperature of the welder to adapt to different heat dissipation requirements. During the welding process, the temperature sensor monitors the temperature of the heat conductive block 250 and the high-voltage package inside the welder body 100. When the temperature exceeds the preset value, the temperature control system automatically adjusts the operating frequency or power of the circulation pump inside the circulating oil box 220 and the piezoelectric ceramic vibration element 310 to enhance the cooling effect. The control panel 110 displays the temperature and power consumption status of the welder in real time, making it convenient for the operator to adjust the welding parameters according to actual conditions.
