Title (EN) ENERGY CONVERTER WITH ANNULAR REGENERATOR, ANNULAR HEATING DEVICE, AND METHOD OF MAKING THE HEATING DEVICE
(FR) CONVERTISSEUR D'ENERGIE A REGENERATEUR ANNULAIRE, DISPOSITIF DE CHAUFFAGE ANNULAIRE, ET PROCEDE POUR SA FABRICATION
Abstract:
(EN) An energy converter working according to e.g. the Stirling cycle has a cold side, a hot side and, arranged therebetween, an annular regenerator (6) through which passes a flow path for the working gas of the converter. This path is substantially radially directed and has an increasing flow area in the direction from the cold side to the hot side. A heating device especially adapted for use as a regenerator in such an energy converter has an inner layer consisting of at least one strip of coarse wire netting; a coil arranged on the inner layer and having a plurality of turns of at least one strip of fine wire netting; and an outer layer wound round the coil and consisting of at least one strip of coarse wire netting. In a method of making such a heating device, an inner layer is formed of at least one strip of coarse wire netting; a coil with a plurality of turns of at least one strip of fine wire netting is wound round the inner layer; and an outer layer of at least one strip of coarse wire netting is wound round the coil.
(FR) Un convertisseur travaillant au cycle Stirling, par exemple, comprend un côté froid, un côté chaud, et, dispose entre les deux, un régénérateur annulaire (6) à travers lequel passe une voie d'écoulement pour le gaz de fonctionnement dudit convertisseur. Ladite voie est sensiblement orientée radialement, et comprend une zone d'écoulement croissante dans le sens menant du côté froid vers le côté chaud. Un dispositif de chauffage spécialement apte à l'usage dans un tel convertisseur comprend une couche interne qui consiste en au moins une bande de grillage à fil grossier. Ledit dispositif est doté également d'une bobine montée sur la couche interne et présentant une pluralité de tours d'au moins une bande de grillage à fil fin ainsi qu'une couche externe en roulant ladite bobine, qui consiste en au moins une bande de grillage à fil grossier. Un procédé possible pour la fabrication dudit dispositif comprend la réalisation d'une couche interne à partir d'au moins une bande de grillage à fil grossier; ensuite une bobine dotée d'une pluralité de tours d'au moins une bande de grillage de fil fin est embobinée autour de la couche interne, et une couche externe d'au moins une bande de grillage à fil grossier est alors embobinée autour de ladite bobine.
