Abstract

L'invention concerne les tubes électroniques amplificateurs fonctionnant en hyperfréquence.The invention relates to electronic amplifier tubes operating in microwave.

Le tube électronique comporte un fourreau tubulaire allongé (10) à l'intérieur duquel se développe un faisceau d'électrons (12), un carter (28) assurant le maintien mécanique du fourreau (10), et des moyens pour assurer un transfert thermique du fourreau (10) vers le carter (28) afin de refroidir le fourreau (10). Les moyens pour assurer le transfert thermique comportent une résine (36) remplissant un volume libre situé entre le fourreau (10) et le carter (28) et des gros granules (38) d'un matériau à résistance thermique inférieur à celle de la résine (36), dans laquelle ils sont noyés.

Figure 00000001
The electronic tube comprises an elongated tubular sheath (10) inside which develops an electron beam (12), a casing (28) ensuring the mechanical maintenance of the sheath (10), and means for ensuring thermal transfer from the sheath (10) to the casing (28) in order to cool the sheath (10). The means for ensuring the thermal transfer comprise a resin (36) filling a free volume situated between the sheath (10) and the casing (28) and large granules (38) of a material with a thermal resistance lower than that of the resin. (36), in which they are embedded.
