An example memory module cooler may include a first liquid manifold, a second liquid manifold, and a cooling tube connected to the first and second liquid manifolds such that. The cooling tube may be connected to the manifolds such that (1) liquid coolant can flow from the first liquid manifold through the cooling tube to the second liquid manifold, and (2) the cooling tube can be rotated relative to the first and second liquid manifolds around a longitudinal axis of the cooling tube. The cooling tube may have an oblong cross-sectional profile.

Systems and methods described herein are directed to rotary heat exchangers configured to transfer heat to a heat transfer medium flowing in substantially axial direction within the heat exchangers. Exemplary heat exchangers include a heat conducting structure which is configured to be in thermal contact with a thermal load or a thermal sink, and a heat transfer structure rotatably coupled to the heat conducting structure to form a gap region between the heat conducting structure and the heat transfer structure, the heat transfer structure being configured to rotate during operation of the device and flow a heat transfer medium in a substantially axial direction through the heat transfer structure. In example devices heat may be transferred across the gap region from a heated axial flow of the heat transfer medium to a cool stationary heat conducting structure, or from a heated stationary conducting structure to a cool axial flow of the heat transfer 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.

Heat pump configurations that provide continuous heat transfer capabilities without any need for electricity. The overall system includes a rotatable hourglass structure situated within a sphere or ovoid container with internal tracks aligned with wheels on the hourglass. With a heat collection component situated on the underside of the container, the rotatable hourglass, being constructed of suitable heat transfer materials, absorb the collected heat in the lower portion of the container, thereby causing the air present therein to expand, forcing a plunger upward from one hourglass chamber to the other. The plunger effectuates operation of a magnetic switch to release the hourglass to rotate and then oscillate from one position to another until the heat collection operation discontinues. With a coolant introduced within the heated chamber (and drawn through pressure differential), heat can be transferred thereto. The heated coolant is then transferred to a reservoir for future utilization.
