Patent

CA 2476217

New designs, methods and processes are described that in which laminated devices and configured in a style named the "ortho" style. To form a device in the ortho style, plates or sheets are machined to have apertures and then stacked together such that the apertures connect and fluid can flow through the device in a direction that is substantially parallel to the direction of sheet thickness. Various laminated devices and processes using them are also described. For example, devices in which non-rectangular microchannels conform around reaction chambers or other bodies that need to be heated or cooled, are described. Features that separate or trip boundary layer and enhance heat transfer are also described.

L'invention concerne de nouveaux procédés, des nouvelles méthodes et des nouvelles conceptions, permettant d'obtenir des dispositifs stratifiés présentant une configuration dans un style dit </= ortho >/= . Pour réaliser un dispositif dans le style ortho, le procédé consiste à usiner des plaques ou des couches de façon à obtenir des ouvertures, puis à empiler ces plaques ou ces couches pour que les ouvertures soient alignées et qu'un fluide puis s'écouler à travers le dispositif, dans une direction sensiblement parallèle à l'épaisseur des couches. L'invention concerne également divers dispositifs stratifiés et des procédés utilisant ces dispositifs. L'invention concerne, par exemple, des dispositifs dans lesquels des microcanaux non rectangulaires sont adaptés aux contours de chambres de réaction ou d'autres corps devant être chauffés ou refroidis. L'invention concerne enfin des éléments permettant de séparer ou d'activer des couches limite et d'augmenter le transfert de chaleur.
