Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, specifically to a rapid cooling device for electric welding machines. Background Technology

[0002] An electric welding machine uses the high-temperature electric arc generated when the positive and negative poles are short-circuited for a moment to melt the welding material on the welding rod and the material to be welded, so that the objects in contact are joined together. Its structure is very simple, just a high-power transformer.

[0003] Existing welding machines, such as the one disclosed in publication number CN219665363U, can ensure that the external airflow is kept at a continuously low temperature to cool the machine core. However, the cooling fans on both sides of this welding machine cannot easily guide the cold air evenly to the heat dissipation components on the transformer inside the machine, resulting in uneven heat dissipation. Therefore, we propose a rapid cooling device for welding machines. Utility Model Content

[0013] 1. In this utility model, heat-conducting plates are fixedly installed on both sides of the transformer component, and upper and lower heat dissipation fins are respectively installed on the upper outer side and lower inner side of the heat-conducting plates. These can evenly transfer the heat at the upper end of the transformer component, so that the heat can be concentrated and dissipated by the upper and lower cooling fans on the upper and lower sides, thereby achieving rapid cooling during the use of the welding machine.

In this utility model, the upper guide inner plate and upper guide outer plate installed at the inner end of the upper cooling fan, and the lower guide outer plate and lower guide inner plate installed at the inner end of the lower cooling fan, can also guide the cooling air respectively, so as to concentrate the airflow to the upper and lower cooling fins to ensure the heat dissipation effect.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a rapid cooling device for an electric welding machine. Example

[0026] Combination Figure 1-6 As shown, the present invention provides a rapid cooling device for a welding machine, comprising: a welding machine body 100 and a heat dissipation assembly 200; the welding machine body 100 includes an inner casing 101 and an outer cover 102 at its inner and outer ends, a fixing frame 103 fixedly installed on both sides of the inner casing 101, and a transformer component 104 fixedly installed at the bottom of the fixing frame 103; the heat dissipation assembly 200 includes a heat-conducting plate 201 fixedly installed at both ends of the transformer component 104, upper heat dissipation fins 202 fixedly installed on the upper outer side of the heat-conducting plate 201, lower heat dissipation fins 203 fixedly installed on the lower inner side of the heat-conducting plate 201, and a fixing frame 104 fixedly installed on one side of the inner casing 101. The upper cooling fan 205 and the lower cooling fan 206 are fixedly installed on the upper and lower sides of the plate 204 and the fixed plate 204 respectively. The upper guide inner plate 207 is fixedly installed in the middle of the inner end of the upper cooling fan 205. The lower guide outer plates 208 are fixedly installed on both sides of the inner end of the lower cooling fan 206. The upper guide outer plates 209 are also fixedly installed on both sides of the inner end of the upper cooling fan 205. The exhaust guide plate 210 is fixedly installed on one side of the upper part of the heat conduction plate 201. The upper heat dissipation vents 211 are arranged on both sides of the outer cover 102. The lower guide inner plates 212 are fixedly installed on both sides of the inner end of the lower cooling fan 206. The lower heat dissipation vents 213 are arranged on one side of the inner box 101.

[0027] Specifically, the welding machine utilizes the high-temperature arc generated when the positive and negative electrodes are momentarily short-circuited to melt the welding rod and the material being welded. The transformer component 104 within the welding machine body 100 has heat-conducting plates 201 fixedly installed on both sides, and upper heat dissipation fins 202 and lower heat dissipation fins 203 installed on the upper outer and lower inner sides of the heat-conducting plates 201, respectively. These heats can evenly transfer heat from the upper end of the transformer component 104, which is then concentrated and cooled by upper cooling fans 205 and lower cooling fans 206, achieving rapid cooling of the welding machine body 100 during use. Simultaneously, upper guide inner plates 207 and upper guide outer plates 209 installed inside the upper cooling fan 205, and lower guide outer plates 208 and lower guide inner plates 212 installed inside the lower cooling fan 206, can also guide the cooling air, concentrating it on the upper ends of the upper heat dissipation fins 202 and lower heat dissipation fins 203 to ensure efficient heat dissipation. Furthermore, the airflow after heat dissipation can also be discharged sequentially through the upper heat dissipation port 211 and the lower heat dissipation port 213 at the outer ends of the upper heat dissipation fin 202 and the lower heat dissipation fin 203, so as to avoid the problem of temperature rise caused by accumulation in the inner box 101. The heat conduction plate 201 fixedly installed on both sides of the transformer component 104 is mainly used to transfer the heat generated by the transformer component 104 during use, so as to transfer the heat to the upper heat dissipation fin 202 and the lower heat dissipation fin 203 at the outer ends. The fixing plate 204 is mainly used to fix the upper cooling fan 205 and the lower cooling fan 206 in a unified manner. The exhaust guide plate 210 installed on one side of the upper part of the heat conduction plate 201 is mainly used to guide the hot air after the upper cooling fan 205 dissipates heat from the upper heat dissipation fin 202, so as to guide it to the upper heat dissipation port 211 for output. The lower heat dissipation port 213 opened on one side of the inner box 101 is located at one end of the lower heat dissipation fin 203 and can be used for the output of the hot air after the lower heat dissipation fin 203 dissipates heat.

[0028] Working principle and usage process of this utility model:

[0029] When the welding machine body 100 cools down rapidly, both the upper cooling fan 205 and the lower cooling fan 206 on one end will start. After the upper cooling fan 205 starts, it will concentrate the cold air from the outside through the upper guide inner plate 207 and the upper guide outer plate 209 on both sides of the inner end and deliver it to the upper heat dissipation fins 202 on the outer side of the upper part of the heat conduction plates 201 at both ends, so as to evenly dissipate heat from the upper heat dissipation fins 202 on both sides. The hot air after being dissipated by the upper heat dissipation fins 202 will be guided by the exhaust guide plate 210 to the outside. The upper heat dissipation vent 211 on the side discharges the cold air. After the lower cooling fan 206 is started, it will divide the cold air from the outside into three groups and evenly deliver it to the lower heat dissipation fins 203 on both sides through the lower guide outer plate 208 and the lower guide inner plate 212 at the inner end, so as to evenly dissipate the heat from the lower heat dissipation fins 203. The hot air after the heat dissipation of the lower heat dissipation fins 203 will be discharged uniformly through the lower heat dissipation vent 213 on the outer side. In this way, the transformer component 104 is evenly and quickly cooled down, thereby achieving rapid cooling of the welding machine body 100.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
