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

Abstract

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.

Description

[0019] In order to better describe the technical characteristics of the constructive arrangement in the cooling system of welding, plasma or laser cutting machines, the following FIGURES are presented:

[0020] FIG. 1 shows the perspective view of the welding, plasma or laser cutting machine, illustrating the heat sink and the set of interconnected tubular fins at the inlet and outlet points.

[0021] The constructive arrangement for welding, plasma or laser cutting machines, object of this utility model, comprises a welding, plasma or laser cutting machine (10) internally containing a heat sink (20) which can have fins (21) or massif, and is usually made of aluminum or copper.

[0022] The heat sink (20) has a tubular fin assembly (30) disposed between the fins (21) of the heat sink, said tubular fins (30) helping the heat exchange and dissipation, in order to cool down the internal components and improve the working efficiency of welding, plasma or laser cutting machines (10).

[0023] The tubular fin assembly (30) is interconnected adjacent to the air or gas inlet (11) and outlet (12) of the equipment, the same air and gas outlet and exhaust point being used in the welding, plasma or laser cutting process. Thus, the same gas or air used in the process passes through the tubular fins (30) before being directed to the cutting or welding torch, so as to help the heat exchange next to the sink 20.

[0024] The air or gas entering the equipment (10) through the inlet point (11) has a low temperature and when it passes through the tubular fin assembly (30) disposed between the heat sink (20), it dissipates the heat generated inside the equipment (10) in order to facilitate the cooling of the internal components.

[0025] The welding or cutting machines (10) provided by the tubular fin assembly (30) can be used without the auxiliary fans normally contained therein, so as to reduce the entry of dust, oil or particles into internal components, increasing life and reducing constant maintenances.

[0026] Optionally, the tubular fin assembly (30) can be used as the single cooling source of the welding, plasma or laser cutting machines (10), allowing the removal of the heat sink and auxiliary fans, so as to enable the construction of smaller equipment.

[0027] Accordingly, the constructive arrangement for cooling system of welding, plasma or laser cutting machines, object of this utility model, has the purpose of improving the cooling system of welding or cutting machines (10) through 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 or gas inlet (11) and outlet (12) of the equipment itself, together with the tubular fins (30) arranged to the sink (20) at an ambient or refrigerated temperature, improving efficiency and increasing the life of the equipment (10). In addition, the tubular fin assembly (30) can be used as the sole source of cooling for welding, plasma or laser cutting machines (10).
