Description

Technical Field

[0001] The utility model relates to the technical field of electric welding machines, in particular to a cooling device for an electric welding machine. Background Art

[0002] The electric welder uses the high-temperature arc generated when the positive and negative poles are short-circuited for an instant to melt the solder on the welding rod and the material to be welded, so that the contacted objects are combined. Its structure is equivalent to a high-power transformer. It uses the principle of inductance. The inductance will produce a huge voltage change when it is connected and disconnected, thereby generating an instantaneous high-voltage arc in a short time. When the electric welder is running, the heat generated by the loss of the winding and the core must be dissipated in time to avoid overheating and insulation damage.

[0003] Therefore, a cooling device is needed to assist in heat dissipation. The existing devices all place the welding machine inside a housing, cooperate with a fan for heat dissipation, and set universal wheels at the bottom to move with the welding machine. However, this heat dissipation device cannot be adapted to welding machines of different sizes, and most of the existing devices do not have an internal fixing mechanism, which causes the welding machine to detach during movement, affecting work efficiency.

[0004] In addition, the existing cooling device has a poor cooling effect on welding machines of different sizes. It only blows in one direction and cannot cool the entire welding machine, resulting in incomplete cooling, which affects the service life and use efficiency of internal parts and reduces the applicability of the device.
