An enclosure and a dynamic heat dissipation method for a heat source inside the enclosure and a dynamic heat dissipation system are provided. The dynamic heat dissipation method includes: acquiring a relatively low temperature area of the enclosure; and driving the heat source to move to the relatively low temperature area. A heat source, which is conventionally at a relatively fixed position, is artificially and actively transformed into a mobile heat source, so as to allow the heat source to be self-adapted to the temperature field; a relatively low temperature area inside the enclosure is searched, taking advantage of the characteristics of temperature differences, the position of the heat source is adjusted and the heat dissipation layout is adjusted, thereby providing the heat source with an optimal heat transfer direction from inside to outside and an enclosure environment where the heat is dissipated at a maximum rate.

A rotating machine with a fluid rotor comprises a set of blades (4) mounted on arms (2) rotating about a main axis (1) of the rotor, the rotor being held by a support structure (5) in an orientation such that said axis (1) is essentially perpendicular to the direction of the flow of fluid, each blade (4) being mounted pivoting about a respective axis of rotation (3) parallel to the main axis (1), the machine comprising a linkage (13, 7, 14) for generating a relative rotational movement of each blade (4) relative to the arm (2) of same at the axis of rotation (3) thereof, in order to thus vary the tilt of the blade relative to the flow of fluid in an angular range. According to the invention, the machine comprises means for collectively modifying the geometry of the linkages (13, 7, 14) from a movement generated at the main axis of the rotor in order to vary the amplitude of the angular range.
