Claims (15)

  1. Tête froide (2) pour un refroidisseur à tube pulsé, comprenant :
    un régénérateur (4) ayant une première extrémité (6) pouvant être raccordée à un compresseur (45) ;
    un tube pulsé (14) ayant une première extrémité (12) et une deuxième extrémité (16);
    un échangeur de chaleur (10) raccordé entre une deuxième extrémité (8) du régénérateur (4) et la première extrémité (12) du tube pulsé (14) ; et
    un dispositif de commande de phase raccordé au niveau de la deuxième extrémité (16) du tube pulsé (14) pour commander la dynamique d'écoulement dans le tube pulsé (14) afin de fournir un refroidissement au niveau de l'échangeur de chaleur (10); dans laquelle :
    le tube pulsé (14) comprend une paroi (15) ayant une partie poreuse destinée à permettre à un gaz de travail d'entrer dans le tube pulsé (14) ou d'en sortir directement à travers la partie poreuse, la partie poreuse étant plus proche de la parallèle que de la perpendiculaire à un axis d'allongement du tube pulsé (14), caractérisée en ce que :
    l'échangeur de chaleur entour coaxialement le tube pulsé.
  2. Tête froide (2) selon la revendication 1, dans laquelle la partie poreuse fait partie d'une paroi partagée qui est partagée entre le tube pulsé (14) et au moins l'un des éléments suivants : le régénérateur (4), l'échangeur de chaleur (10), un distributeur d'écoulement (11) entre le tube pulsé (14) et le dispositif de commande de phase.
  3. Tête froide (2) selon la revendication 2, dans laquelle le régénérateur (4) entoure coaxialement le tube pulsé (14) et la partie poreuse fait partie d'une paroi partagée qui est une paroi radialement interne du régénérateur (4).
  4. Tête froide (2) selon la revendication 2, dans laquelle le tube pulsé (14) entoure coaxialement le régénérateur (4) et la partie poreuse fait partie d'une paroi partagée qui est une paroi radialement interne du tube pulsé (14).
  5. Tête froide (2) selon la revendication 4, dans laquelle le régénérateur (4) est sensiblement cylindrique et le tube pulsé (14) a une section transversale sensiblement annulaire.
  6. Tête froide (2) selon l'une quelconque des revendications précédentes, dans laquelle la partie poreuse s'étend depuis la deuxième extrémité (8) du régénérateur (4) suivant une partie du régénérateur (4) vers la première extrémité (6) du régénérateur (4), sans atteindre la première extrémité (6) du régénérateur (4).
  7. Tête froide (2) selon l'une quelconque des revendications précédentes, dans laquelle la porosité de la partie poreuse de la paroi (15) décroît en fonction d'une séparation croissante depuis la deuxième extrémité (8) du régénérateur (4).
  8. Tête froide (2) selon la revendication 1, dans laquelle le tube pulsé (14) est orienté de sorte que la deuxième extrémité (16) du tube pulsé (14) soit plus éloignée de la première extrémité (6) du régénérateur (4) que de la première extrémité (12) du tube pulsé (14).
  9. Tête froide (2) selon l'une quelconque des revendications précédentes, dans laquelle le dispositif de commande de phase est configuré pour commander la dynamique d'écoulement à l'aide d'au moins un composant de commande de phase fluidique afin de commander l'écoulement de gaz vers et hors de la deuxième extrémité (16) du tube pulsé (14), les composants de commande de phase fluidique étant configurés pour fonctionner sans l'utilisation d'une partie mobile solide quelconque.
  10. Tête froide (2) selon l'une quelconque des revendications précédentes, dans laquelle le dispositif de commande de phase fournit l'un ou les deux d'un amortissement et d'une inertie.
  11. Tête froide (2) selon l'une quelconque des revendications précédentes, dans laquelle le dispositif de commande de phase comprend un piston et un cylindre en communication fluidique avec la deuxième extrémité (16) du tube pulsé (14).
  12. Tête froide (2) selon l'une quelconque des revendications précédentes, dans laquelle la partie poreuse de la paroi (15) est formée à partir d'une feuille électroformée.
  13. Tête froide (2) selon la revendication 12, dans laquelle la feuille électroformée est prise en sandwich entre des couches de treillis qui agissent pour uniformiser et/ou redresser l'écoulement de gaz traversant la partie poreuse de la paroi (15).
  14. Tête froide (2) selon l'une quelconque des revendications précédentes, la tête froide (2) étant configurée pour fonctionner comme un refroidisseur multi-étage et a un premier ensemble de tube pulsé comprenant :
    un premier régénérateur (4) ayant une première extrémité (6) pouvant être raccordée à un compresseur (45) ;
    un premier tube pulsé (14) ayant une première extrémité (12) et une deuxième extrémité (16) ; et
    un premier échangeur de chaleur (10) raccordé entre une deuxième extrémité (8) du premier régénérateur (4) et la première extrémité (12) du premier tube pulsé (14), dans laquelle
    le dispositif de commande de phase est raccordé au niveau de la deuxième extrémité (16) du premier tube pulsé (14) pour commander la dynamique d'écoulement dans le premier tube pulsé (14) afin de fournir un refroidissement au niveau du premier échangeur de chaleur (10),
    le premier tube pulsé (14) comprend une paroi (15) ayant la partie poreuse destinée à permettre à un gaz de travail d'entrer dans le premier tube pulsé (14) ou d'en sortir directement à travers la partie poreuse, la partie poreuse étant plus proche de la parallèle que de la perpendiculaire à un axis d'allongement du premier tube pulsé (14) ; et
    la tête de froid (2) comprend en outre un deuxième ensemble de tube pulsé à étage comprenant :
    un tube pulsé supplémentaire (74) raccordé directement au premier tube pulsé (14) dans la région du premier échangeur de chaleur (10) et de telle sorte qu'il existe un raccordement fluidique continu entre le premier tub pulsé (14) et le tube pulsé supplémentaire (74), le tube pulsé supplémentaire (74) étant couplé fluidiquement au dispositif de commande de phase via ledit raccordement fluidique continu ;
    un régénérateur supplémentaire (72) configuré pour recevoir un gaz de travail depuis le premier régénérateur (4) ; et
    un échangeur de chaleur supplémentaire (76) configuré pour fournir un refroidissement à une température inférieure au refroidissement fourni par le premier échangeur de chaleur (10).
  15. Refroidisseur à tube pulsé comprenant une tête froide (2) selon l'une quelconque des revendications précédentes et un compresseur (45) raccordé à la première extrémité (6) du régénérateur (4).
