[0013] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0014] like Figures 1-9 As shown, a portable self-cooling welding machine according to an embodiment of the present invention includes: a chassis assembly, an air duct assembly, and a cooling assembly; The chassis assembly includes: a chassis 1 and a ventilation grille 2; Both sides of the box body 1 are provided with ventilation grilles 2; The air duct assembly is located inside the housing 1, and the air duct assembly includes: a circuit board 4, a sealing plate 5, and a sealing plate 6; The circuit board 4 and the sealing plate 5 are arranged opposite to each other. The sealing plate 6 is located on the top of the circuit board 4 and the sealing plate 5 and is used to connect the circuit board 4 and the sealing plate 5. There is an air duct between the circuit board 4 and the sealing plate 5. The inlet end and the outlet end of the air duct are respectively facing the two ventilation grilles 2. The cooling assembly includes: a cooling fan 7 and a cooling mechanism 8; The cooling fan 7 is located at the ventilation grille 2 at the inlet end of the air duct, and the cooling mechanism 8 is located inside the air duct and is positioned corresponding to the circuit board 4.

[0015] This application forms an air duct between the circuit board 4 and the sealing plate 5, and seals the top of the air duct with the sealing plate 6. The cooling fan 7 blows air from outside the housing 1 into the housing 1 through the ventilation grille 2. The cooled air passes through the air duct and cools the circuit board 4. The cooling mechanism 8 improves the cooling efficiency of the circuit board 4. After passing through the air duct, the cooled air leaves the housing 1 through the ventilation grille 2 at the other end, realizing automatic cooling of the welding machine, ensuring the service life of the circuit board 4, avoiding welding machine failure, and ensuring the operator's work efficiency.

[0016] like Figures 1-4As shown, the box body 1 has an inclined plate 11, a top plate 12, and a pull rod 3; Both sides of the box body 1 are provided with inclined plates 11. The inclined plates 11 are used to connect the ventilation grille 2 and the top plate 12. A horizontally arranged tie rod 3 is provided at the connection between the ventilation grille 2 and the inclined plate 11. An inclined tie rod 3 is provided at the connection between the inclined plate 11 and the top plate 12. A vertically arranged tie rod 3 is provided on the top plate 12.

[0017] In this embodiment, five pull rods 3 are provided on the housing 1. Two sets of pull rods 3 are symmetrically arranged on the left and right sides, which makes it easier for two people to carry the welding machine together. The inclined pull rods 3 make it easier for two people to lift the welding machine together. The pull rods 3 on the top plate 12 make it easier for a single person to lift the welding machine.

[0018] like Figures 3-6 As shown, the soldering surface of the circuit board 4 is oriented towards the air duct.

[0019] In this embodiment, by setting the soldering surface of the circuit board 4 towards the air duct, the cooling air in the air duct cools the circuit board 4, while preventing dust in the air duct from adhering to the component surface of the circuit board 4, thus ensuring that the components on the circuit board 4 work normally.

[0020] like Figures 3-7 As shown, the circuit board 4 includes: a first circuit board 41 and a second circuit board 42; The first circuit board 41 and the second circuit board 42 are connected to each other. The first circuit board 41 is located near the cooling fan 7, and the cooling mechanism 8 is located corresponding to the first circuit board 41.

[0021] The cooling mechanism 8 includes: a first heat sink 81, a second heat sink 82, and a third heat sink 83; The first heat sink 81, the second heat sink 82 and the third heat sink 83 are all heat sink fins. The first heat sink 81 is disposed on the bottom surface of the housing 1, and the back of the first heat sink 81 is disposed facing the first circuit board 41. The fin surfaces of the second heat sink 82 and the third heat sink 83 are disposed opposite to each other, and the third heat sink 83 is located above the second heat sink 82.

[0022] In this embodiment, the first circuit board 41 is a functional circuit board 4. The functional circuit board 4 generates a lot of heat when it is working, so a cooling mechanism 8 is required to dissipate heat from the first circuit board 41.

[0023] like Figures 8-9 As shown, the ventilation grille 2 includes: a first grille 21, a second grille 22, and a third grille 23; The second grille 22 is located between the first grille 21 and the third grille 23. The first grille 21 is located on the outside of the box body 1. The first grille 21 is provided with an inclined grille plate. The second grille 22 is provided with rectangular ventilation holes evenly distributed. The third grille 23 is provided with strip-shaped ventilation holes.

[0024] In this embodiment, the first grille 21, which is set at an angle, prevents rainwater from entering the housing 1 and prevents rainwater from damaging the circuit board 4.

[0025] Above, refer to Figures 1-9 This application describes a portable self-cooling welding machine according to an embodiment of the present invention. An air duct is formed between a circuit board 4 and a sealing plate 5. The top of the air duct is sealed with a sealing plate 6. A cooling fan 7 blows air from outside the housing 1 into the housing 1 through a ventilation grille 2. The incoming cooling air passes through the air duct and cools the circuit board 4. A cooling mechanism 8 improves the cooling efficiency of the circuit board 4. After passing through the air duct, the cooling air exits the housing 1 through the ventilation grille 2 at the other end, achieving automatic cooling of the welding machine, ensuring the service life of the circuit board 4, preventing welding machine malfunctions, and guaranteeing the operator's work efficiency.
