Patent

CA 2351687

The present invention relates to the problem of obtaining a device for increasing the heat transfer from an object (3; 73; 103). The problem is solved by means of a device (1; 71; 101) comprising one or more oscillating membranes (21, 25; 81; 121, 125) for generating an air motion of air surrounding the object (3; 73; 103). Further, the device comprises means (31, 33; 87; 129, 131) for affecting the air motion so that this causes a continuous exchange of air surrounding the object (3; 73; 103). The continuous exchange of the surrounding air means that the object (3; 73; 103) is surrounded by relatively cold air all the time, and therefore the heat transfer from the object (3; 73; 103) to the surrounding air is efficient.

L'invention porte sur le problème de l'obtention d'un dispositif accroissant le transfert de la chaleur provenant d'un objet (3; 73; 103). Ledit problème est ici résolu à l'aide d'un dispositif (1; 71; 101) présentant une ou plusieurs membranes oscillantes (21, 25; 81; 121, 125) produisant un déplacement d'air autour de l'objet (3; 73; 103), et comprenant en outre des moyens (31, 33; 87; 129, 131) agissant sur lesdits déplacements d'air pour qu'ils entraînent un renouvellement continu de l'air entourant l'objet (3; 73; 103). Ce renouvellement continu signifie que l'objet (3; 73; 103) est entouré en permanence d'air relativement froid, d'où un transfert de chaleur efficace de l'objet (3; 73; 103) vers l'air environnant.
