The heat exchanger includes an inner casing extending circumferentially around the central axis and securable to the shaft for concurrent rotation therewith, and an outer casing extending circumferentially around the central axis and secured to the inner casing, the outer casing located radially outwardly of the inner casing relative to the central axis. First conduits are secured to the outer casing and to the inner casing for rotation about the central axis, the first conduits located radially between the outer casing and the inner casing, and circumferentially distributed about the central axis. First passages are defined in the first conduits. Second passages are circumferentially interspaced between the first passages and are located radially between the inner casing and the outer casing. The second passages are in heat exchange relationship with the first passages.

The invention disclosed generally relates to a heat exchange system comprising an outer tube, an inner tube generally located within the outer tube and comprising a longitudinal axis running along the length of the inner tube, and a fixed elongate member located within the inner tube and comprising a longitudinal axis running along the length of the elongate member. The inner tube is mounted on a rotational drive system to rotate the inner tube about its longitudinal axis. The system further includes at least one inlet and at least one outlet. One or more projecting members project from an outer surface of the elongate member, an outer surface of the inner tube or an inner surface of the outer tube.

A heat sink assembly includes a thermally conductive support member configured to be attached to a heat source and a heat sink. An adjustable mechanism is configured to moveably connect the thermally conductive support member to the heat sink. The adjustable mechanism permits the heat source to be moved relative to the heat sink without requiring access to the adjustable mechanism. The heat sink assembly provides a mechanically adjustable and supportive system having a thermally conductive path for heat removal from the object. The integral movable adjustment mechanism permits the thermally conductive member to translate without loss of the thermal path between the two ends. The heat source can move and become rigidly fixed in location without direct access. A compression mechanism may provide a continuous force between the support member and the heat sink as the support member is translated to permit movement of the heat generating source.

The heat exchanger includes an inner casing extending circumferentially around the central axis and securable to the shaft for concurrent rotation therewith, and an outer casing extending circumferentially around the central axis and secured to the inner casing, the outer casing located radially outwardly of the inner casing relative to the central axis. First conduits are secured to the outer casing and to the inner casing for rotation about the central axis, the first conduits located radially between the outer casing and the inner casing, and circumferentially distributed about the central axis. First passages are defined in the first conduits. Second passages are circumferentially interspaced between the first passages and are located radially between the inner casing and the outer casing. The second passages are in heat exchange relationship with the first passages.

Contoured fan blades and associated systems and methods are disclosed herein. A representative embodiment includes a hub and multiple curved fan blades circumferentially arranged around, and coupled to, the hub. Individual fan blades can have a tip, a first curved edge, and a second curved edge. The first and second curved edges extend over at least part of the length between the hub to the tip of the fan blade. The fan blade is formed with multiple upper channels and multiple lower channels. The multiple upper and lower channels extend from the first curved edge to the second curved edge.

A thermal-energy exchange and storage system has a borefield with a core zone and at least one capacity expansion zone. Each of the core zone and the at least one capacity expansion zone have a plurality of boreholes. The at least one capacity expansion zone is positioned outwards from and encircling the core zone and each additional capacity expansion zone is positioned outwards from and encircling the previous capacity expansion zone. A heat source is provided in fluid communication with a heat exchanger. An injection system circulates an operating fluid. The injection system has at least one U-tube installed within the plurality of boreholes and operating fluid is circulated between the at least one U-tube and the heat exchanger for transferring heat from the heat source. An extraction system is provided for extracting heat stored in the system for use in an infrastructure.

The device (1) for bringing a gas and a liquid into contact includes an enclosure (E), first means (5) for introducing into the enclosure and circulating therein a gas stream (G), second means (6) for introducing into the enclosure and circulating therein a liquid stream (L) that circulates inside the enclosure (E) in the same direction as the gas stream (G), and means (4A) for mixing the gas stream (G) and the liquid stream (L). These mixing means (4A) are positioned inside the enclosure (E) in the path of the gas stream and liquid stream and are capable of locally deflecting upward, and/or of locally causing to rise, at least one portion of the gas stream and liquid stream, so as to locally create turbulences in the gas stream and in the liquid stream.
