• the fluid is extracted from the cooling circuit via the outlet orifice 334.
• the fluid circulates through the circuit cooling with a controlled flow. Of course, the direction of flow of the fluid can be reversed.
• the fixed part 310 the mobile part 320 and all the branches 311, 312,
• the mount 300 is made in one piece.
• the cooling circuit 380 is made in one piece with all the elements of the frame 300, that is to say that it is made in one piece with the fixed part 310, the mobile part 320 and each joint 315.
• the frame 300 is made from a metallic material.
• the fixed part 310, the movable part 320 and each articulation 315 comprise a metallic material.
• the metallic material includes, for example, aluminum, copper or stainless steel.
• the frame 300 is manufactured by additive manufacturing.
• the frame 300 illustrated in Figures 7 and 8 is flexible in translation along a translation axis L 5 .
• this other articulation is also a flexible articulation allowing another translational movement along another translational axis between the movable part 320 and the other movable part.
• the other axis of translation is transverse with respect to the axis of translation L 5 .
• a frame comprising a flexible articulation in rotation, another flexible articulation in translation, the two flexible articulations being arranged in series, and the cooling circuit integrated into the frame.
• the cooling circuit passes in series via the fluid inlet port 332 inside the fixed part of the frame, the first articulation, the second articulation, the movable part of the frame, then passes back through the second articulation, the first articulation then the fixed part of the frame in the direction of the fluid outlet orifice.
