Description

Technical Field

[0001] The present application relates to the technical field of electric welding guns, and in particular to a cooling device for an electric welding machine. Background Art

[0002] With the rapid development of industrial technology, electric welding machines, as an indispensable and important equipment in the field of metal processing, have a direct impact on production efficiency and product quality due to the stability and reliability of their working performance. Electric welding machines, as an indispensable and important equipment in modern welding technology, have been continuously evolving with the progress of power technology, electronic control technology and materials science. They have become a key tool in many fields such as industrial production, construction, and automobile maintenance.

[0003] During the operation of the electric welder, the high temperature generated by the current passing through the electrode causes the internal components of the welder to bear a huge heat load. Long-term high-temperature operation will not only reduce the working efficiency of the welder, but may also cause equipment failure and even shorten the service life of the equipment. The common cooling methods for electric welders on the market currently mainly use fans and natural air cooling. The efficiency of fans is low and the cooling range is not large. Natural air cooling relies on natural convection heat dissipation of ambient air, with limited effect and easily affected by ambient temperature. To this end, we propose a cooling device for electric welders to solve the above problems. Utility Model Content

[0013] At least one of the above technical solutions adopted in the embodiments of the present application can achieve the following beneficial effects:

[0014] Firstly, cold water is delivered into the cold pipe through the water pump in the cold head to cool the heat sink. The cold water in the cold pipe becomes hot water, and the temperature of the air around the heat sink will decrease. The rotation of the second fan causes the air in the outer shell to flow, thereby cooling the interior of the welding machine, thereby achieving the effect of increasing the working efficiency of the welding machine. The overall sealing of the outer shell can also isolate the interference of dust on the welding machine, thereby extending the service life of the equipment and reducing the probability of failure of the welding machine.
