Title
(EN) SKIN TREATMENT DEVICE
(FR) DISPOSITIF DE TRAITEMENT CUTANÉ
Abstract
(EN)
The invention relates to a skin treatment device comprising a handle (1) with an energy supply, an application head (2) with at least one heat source comprising at least one semiconductor light source (3), and at least one heat sink comprising cooling fins (4). The heat sink is located remote from the heat source within the handle (1). Further, the heat source is thermally connected to the heat sink by means of a heat transfer system (6, 6', 6'') which comprises an hermetically sealed tubular body containing a working medium, wherein the pressure within the tubular body is chosen such that the working medium is a saturated liquid at room temperature and may be vaporized by the heat source.
(FR)
L'invention concerne un dispositif de traitement cutané comprenant une poignée (1) comportant une alimentation électrique, une tête d'application (2) équipée d'au moins une source de chaleur comprenant au moins une source de lumière à semi-conducteur (3), et au moins un puit de chaleur comprenant des ailettes de refroidissement (4). Le puits de chaleur est situé à distance de la source de chaleur à l'intérieur de la poignée (1). En outre, la source de chaleur est thermiquement reliée au puits de chaleur au moyen d'un système de transfert de chaleur (6, 6', 6'') qui comprend un corps tubulaire hermétiquement fermé contenant un milieu de travail, la pression à l'intérieur du corps tubulaire étant choisie de telle sorte que le milieu de travail est un liquide saturé à température ambiante et peut être vaporisé par la source de chaleur.
