The present invention relates generally to the rotary high density heat exchangers. In one embodiment, the present invention relates to rotary high density heat exchangers that contain one or more fan blades where each fan blade contains heat exchanging surfaces on the surface thereof.

The invention relates to a device for converting thermal energy of a low temperature into thermal energy of a high temperature by means of mechanical energy, and vice versa, comprising a rotor which is mounted so as to rotate about a rotational axis and in which a flow channel is provided for a working medium that circulates in a closed circuit process, said medium being conducted outwards, relative to the rotational axis, in a compression unit in order to increase pressure, and being conducted inwards, relative to the rotational axis, in an expansion unit in order to reduce pressure. At least one heat exchanger is provided for exchanging heat between said working medium and a heat exchange medium.

An air conditioning system having a compact configuration may include an evaporator and a heater core that have a cylindrical shape. The evaporator defines a cavity. The heater core is positioned within the cavity such that the evaporator and the heater core are coaxially positioned with each other about a center axis. The heater core is configured to rotate about the center axis to draw in air.

A rotary heat exchanger includes: a tubular-shaped heat transfer tubular body (3) which is rotatable with a central axis (C) as a rotation center, which allows a first medium (11) to flow therein, and outside of which a second medium (12) having a temperature different from temperature of the first medium (11) flows; a central member (2) which is provided on an inner side of the heat transfer tubular body (3) in a radial direction and which is fixed coaxially with the heat transfer tubular body (3); and an outer sliding contact member (6) which is in sliding contact with an outer circumferential surface of the heat transfer tubular body (3), and the heat transfer tubular body (3) is rotatably supported with respect to the central member (2) via bearings (17, 18) disposed at two end portions of the central member (2) in an axial direction.
