Claim 0:
1. An electronic system comprising:
an external jacket;
a wall of an internal cavity that is to be cooled;
at least one fixed connection fixing the external wall of the internal cavity that is to be cooled to the external jacket;
a heat-transport fluid cooling circuit comprising grooves on the external surface of the wall of the internal cavity and a sleeve comprising a flexible portion positioned flush with the external surface of the external wall of the internal cavity, thereby forming mini-canals with said grooves, having a non-zero longitudinal component, the flexible portion comprising an end first part of a first thickness greater than a second thickness of a contiguous second part of the flexible portion, the second part being contiguous with a third part of the sleeve which has a third thickness greater than the first and second thicknesses, and in contact with a jacket positioned on the outside of the external jacket;
at least one radial extension of the wall of the internal cavity creating connecting points configured to hold the sleeve in place; and
a space between the external wall of the internal cavity and the sleeve at the flexible portion of the sleeve.
