CONSTRUCTIVE ARRANGEMENT FOR COOLING SYSTEM OF WELDING, PLASMA OR LASER CUTTING MACHINES

摘要

A constructive arrangement is described for a cooling system of welding, plasma or laser cutting machines comprising a tubular fin assembly (30) interconnected to the heat sink (20) arranged in the inner portion of the welding, plasma or laser cutting machine (10), helping the heat dissipation through the use of the air and gas inlet and outlet of the equipment itself near the fins arranged to the heat sink at an ambient or refrigerated temperature, improving efficiency and increasing equipment life. In addition, the tubular fin assembly can be used as the sole source of refrigeration in the welding, plasma cutting or laser machines. Solving and improving the drawbacks identified in the prior art.
