[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0020] First, combine Figures 1 to 3 A novel heat dissipation structure of a welding machine according to an embodiment of the utility model is described, which is used to enhance the heat dissipation of the welding machine and has a wide range of application scenarios.

[0021] like Figures 1 to 3 As shown, the novel heat dissipation structure of the welding machine according to the embodiment of the utility model comprises: a fan 1; an air guide duct 2, and a radiator 3.

[0022] Specifically, Figures 1 to 3 As shown, in this embodiment, one end of the air duct 2 is fixed at the air outlet of the fan 1, and the cross-sectional areas at both ends of the air duct 2 are larger than the cross-sectional area of ​​the middle part of the air duct 2; the air duct 2 is a Laval tube. According to the Laval effect in fluid mechanics, when a channel is formed, if the cross-sectional area of ​​the channel gradually decreases, the speed at which the fluid passes through can be gradually increased. The front section of the air duct 2 contracts, which can accelerate the flow rate of the wind flow, inhale a large amount of wind flow, increase the guide speed on the basis of increasing the air volume, and flow into the rear section of the air duct 2 in a higher speed jet state; the hourglass-shaped air duct 2 can also reduce the wind flow loss on the way to the radiator 3, correct and maintain the forward direction of the wind flow, so that the wind flow inhaled by the fan 1 is used for maximum heat dissipation; the radiator 3 is arranged at the other end of the air duct 2; the air duct 2 guides the wind flow of the fan 1 to the radiator 3, and the radiator 3 dissipates the heat of the welding machine.

[0023] Further, if Figure 2~3 As shown, in this embodiment, the radiator 3 includes: a heat transfer plate 31, the outer side of the heat transfer plate 31 is connected to the heating surface of the electronic components of the welding machine, and one end of the heat transfer plate 31 is arranged at the other end of the air duct 2; a plurality of heat sinks 32, the plurality of heat sinks 32 are arranged side by side on the inner side of the heat transfer plate 31, and a heat dissipation air duct is formed between adjacent heat sinks 32, the heat dissipation air duct is connected to the air duct 2, and the air flow transported by the air duct 2 enters the heat dissipation air duct to dissipate the heat of the heat sink 32, thereby dissipating the heat of the electronic components inside the welding machine.

[0024] Further, if Figure 2~3As shown, in this embodiment, the heat sink 32 is shuttle-shaped, and the two side surfaces of the heat sink 32 opposite to the heat dissipation duct are arc-shaped, which increases the heat dissipation area. At the same time, in the Coanda effect, when the fluid encounters an obstacle, the speed of the fluid will decrease at the front edge of the obstacle and increase at the rear edge of the obstacle. This change in speed can cause the fluid to form an alternating vortex structure behind the obstacle. The alternating vortices break away from the two sides of the obstacle at a regular frequency and move downstream along the direction of the fluid. The bending effect of the heat sink 32 has this effect. The wind flow accelerated by the air guide duct 2 is cut and enters the heat dissipation duct between the heat sink 32 respectively, reducing the collision of the wind flow when entering the radiator 3, reducing the loss of wind potential energy, and reducing high-frequency vibration and thus reducing high-frequency whistling noise, thereby extending the service life of the welding machine; the two ends of the heat dissipation duct are expansion sections, and the middle part of the heat dissipation duct is a contraction section. The height of the contraction section is less than the height of the expansion section. The Laval effect is used to increase the speed of the wind flow passing through the radiator 3, accelerate the heat transfer on the heat sink 32, and improve the heat dissipation efficiency.

[0025] Further, if Figure 2~3 As shown, in this embodiment, a plurality of heat sinks 32 are evenly distributed on the inner side of the heat transfer plate 31, so that the heat dissipation is more uniform and the heat dissipation effect is better.

[0026] The wind from the fan 1 inhales a large amount of wind through the air duct 2, while increasing the wind speed, and then flows into the heat dissipation air duct between the heat sinks 32, increasing the speed of the wind passing through the radiator 3, accelerating the heat transfer on the heat sink 32, and dissipating the heat from the heat sink 32.

[0027] Above, refer to Figures 1 to 3 A novel heat dissipation structure of a welding machine according to an embodiment of the utility model is described, which can increase the working efficiency of the air duct in the heat dissipation part of the welding machine and reduce the energy consumption required for heat dissipation of the welding machine.

In the absence of further restrictions, the elements defined by the sentence "comprises..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
