Description

Technical Field

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

[0002] What is an electric welding machine? It is an electrical device used to weld metal materials. It converts electrical energy into heat energy and 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, thereby achieving the fusion connection of metals or other materials.

[0003] Currently, welding machines typically consist of a high-power transformer and a welding machine casing. It converts high-voltage, low-current power into low-voltage, high-current power to meet welding requirements. This high-power transformer generates a significant amount of heat during operation. Existing welding machines often use cooling fans to dissipate heat from the internal casing. However, in practical use, it has been found that this cooling method struggles to maintain the transformer at a suitable temperature, resulting in ineffective heat dissipation.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of poor heat dissipation effect when using only a cooling fan in the prior art, this utility model provides a cooling device for an electric welding machine. The cooling device includes: a main body adapted to be mounted above the electric welding machine, and an exhaust fan installed on the main body; a first side frame adapted to be mounted on the circumferential outer side of the side heat dissipation holes of the electric welding machine and fixedly connected to the main body; a second side frame arranged opposite to the first side frame and telescopically connected to the main body; a folded rubber membrane disposed between the second side frame and the main body; and magnetic suction components suitable for connection to the electric welding machine disposed on the first and second side frames.

[0006] This utility model discloses a cooling device for a welding machine, comprising a main body, a first side frame, and a second side frame. These three components abut against the top and sides of the welding machine, respectively, forming a closed space. The first and second side frames cover the outer periphery of the side ventilation holes, and an exhaust fan is installed on the main body. The exhaust fan draws air from inside the welding machine through the side ventilation holes, accelerating the airflow and enhancing the cooling effect. The second side frame is telescopically connected to the main body, and a folded rubber membrane is provided between the second side frame and the main body, allowing the cooling device to adapt to welding machines of different widths, thus enhancing its applicability. Magnetic attachments are provided on the first and second side frames for easy fixation to the welding machine, simplifying operation and making it convenient to use. Through the above-described design, this utility model's cooling device for a welding machine adds an exhaust structure to the outside of the welding machine, accelerating the airflow and enhancing its cooling effect.

[0007] Furthermore, the main body includes a frame, a top plate mounted on the frame, and side plates mounted on the frame; the exhaust fan is mounted on the top plate.

[0008] Furthermore, a support rod suitable for abutting against the welding machine is installed on the top plate.

[0009] Furthermore, the frame includes a crossbeam, a longitudinal beam connected to the crossbeam, and a column connected to the crossbeam and the longitudinal beam; the second side frame includes a guide column that forms a telescopic connection with the crossbeam, a frame body connected to the guide column, and a panel installed on the frame body.

[0010] Furthermore, a guide hole matching the guide post is provided on the crossbeam.

[0011] Furthermore, a connecting rod adapted to face the welding machine is provided on the frame, and the magnetic suction element is mounted on the connecting rod.

[0012] Furthermore, the crossbeam, the longitudinal beam, and the column form a detachable connection.

[0013] Furthermore, a connector is provided between the crossbeam, the longitudinal beam, and the column.

[0014] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0015] (1) The main body, the first side frame and the second side frame are respectively attached to the top and sides of the welding machine and form a closed space with the welding machine. The first side frame and the second side frame are covered on the circumferential outside of the side heat dissipation holes, and an exhaust fan is installed on the main body. The exhaust fan can draw air from the welding machine through the side heat dissipation holes, accelerate the flow of air inside the welding machine, and thus enhance the heat dissipation effect of the welding machine.

[0016] (2) The second side frame is connected to the main body in a telescopic fit, and a folded rubber membrane is provided between the second side frame and the main body, so that the cooling device can adapt to welding machines of different widths and enhance the applicability of the cooling device.
