Abstract
A part for a Joule-Thomson cooler, comprising a gas discharge pipe and a seal closing the gas discharge pipe, the seal being capable of breaking, at least partially, under the effect of gas expansion triggered by the cooler so as to allow the gas to be discharged out of the cooler through the gas discharge pipe. The part is obtained by an additive manufacturing method that comprises stacking layers of powder along a stacking axis in order to form the part, the stacking axis being parallel to a central axis of a second gas discharge pipe separate from the first discharge pipe.
