<p>Heat exchanger between a relatively hot fluid flowing through an annular or tubular space bounded by a heat conducting wall and a relatively cold fluid which surrounds and externally embraces at least part of said annular or tubular space and which comprises a rotor mounted rotationally in said annular space, as well as a source of motion which can be kinematically connected to the rotor to create turbulence and fling at least part of the hot fluid against the wall of the annular space. <IMAGE></p> |
