Title (EN) IMPROVED COOLING OF A WELDING IMPLEMENT
(FR) REFROIDISSEMENT PERFECTIONNÉ D’UN OUTIL DE SOUDAGE
Abstract: front page image
(EN)A welding implement and a method of extracting heat from a welding implement (32) are disclosed. The welding implement (32) includes one or more heat pipes (96) which transfer thermal energy away from the torch head (102). A fluid, such as a shielding gas, may then convectively transfer the thermal energy away from the welding implement (32). The present invention thus provides a handheld welding implement (32) that is compact, such that it can be used in confined spaces, and operated for longer periods of time, since the improved heat dissipation helps to maintain the welding implement at a temperature that an operator may hold.
(FR)La présente invention se rapporte à un outil de soudage et à un procédé d’extraction de chaleur d’un outil de soudage (32). L’outil de soudage (32) comprend un ou plusieurs caloducs (96) qui transfèrent l’énergie thermique loin du bec de chalumeau (102). Un fluide, tel qu’un gaz protecteur, peut ensuite transférer par convection l’énergie thermique loin de l’outil de soudage (32). La présente invention a ainsi pour objet un outil de soudage portatif (32) qui est compact, de sorte qu’il puisse être utilisé dans des espaces restreints, et qui fonctionne pendant de plus longues périodes, étant donné que l’amélioration de la dissipation de chaleur aide à maintenir l’outil de soudage à une température permettant à un opérateur de le tenir.
