Title
(EN) HEAT EXCHANGER FOR HIGH-POWER SEMICONDUCTOR LASERS
(FR) ECHANGEUR DE CHALEUR POUR LASERS SEMI-CONDUCTEURS PUISSANTS
Abstract
(EN) The invention relates to semiconductor lasers and is particularly directed at heat exchangers to be fixed in order to cool rulers of high power laser diode arrays. The structure of the microchannels used for the flow of cooling liquid consists of two communicating arrays of microchannels with slits, whereby said arrays are made from a material with good thermal conductivity and are mounted in a common housing. One of these arrays, used for heat dissipation, is placed directly under the location where the laser is mounted. The axes of the channels of the two arrays are perpendicular. The second array consists of subsystems of non-communicating microchannels, which are used to supply and to remove cooling liquid. The flow of liquid generates turbulence. The object of the invention provides a better heat dissipation from the active areas of the laser and is moreover a high tech product.
(FR) L'invention appartient au domaine des lasers semi-conducteurs et concerne notamment des échangeurs de chaleur destinés à être fixés à demeure pour refroidir des règles et des réseaux de diodes laser haute puissance. La structure des microcanaux destinés à l'écoulement du liquide de refroidissement est constituée par deux réseaux communicants de microcanaux à fente, lesdits réseaux étant faits à partir d'un matériau qui conduit bien la chaleur et disposés dans un boîtier commun. Un de ces réseaux, destiné à l'évacuation de la chaleur, est disposé directement sous l'emplacement de fixation du laser. Les axes des canaux des deux réseaux sont perpendiculaires. Le deuxième réseau est constitué de sous-systèmes de microcanaux non communiquants, qui servent à amener et à évacuer le liquide de refroidissement. L'écoulement du liquide génère des turbulences. L'objet de l'invention permet une meilleure évacuation de la chaleur depuis les zones actives du laser et se présente en outre comme un produit de haute technicité.
