摘要： A heat exchanger includes a shell, a coiled tube, and a swirler. The shell has an inlet and an outlet and forms a cavity. A first of a liquid refrigerant and a vapor refrigerant enters the inlet of the shell. The coiled tube is positioned within the cavity and is connected to an inlet tube from outside the shell and an outlet tube to outside the shell. A second of the liquid refrigerant and the vapor refrigerant enters the inlet tube of the coiled tube. The swirler is arranged adjacent the inlet of the shell and is dimensioned to distribute the first of the liquid refrigerant and the vapor refrigerant across the coiled tube.

摘要： The present application discloses a microchannel flat tube and a microchannel heat exchanger. The microchannel flat tube includes a flat tube body and a row of channels. The row of channels is arranged in the flat tube body along a width direction. The row of channels extends through the flat tube body along a length direction. A cross-section of each channel includes a first width in the width direction and a first height in a thickness direction. The row of channels at least includes a first group of first channels, a second group of second channels and a third group of third channels along the width direction. The first widths of the first channels, the second channels and the third channels decrease at a fixed rate, thereby facilitating the control of the thickness of the microchannel flat tube and improving the heat exchange efficiency of the third channels.

摘要： Apparatus related to thermal storage and exchange systems for use in buildings to selectively cool and/or heat a heat storage medium and cause said medium to reversibly pass between a liquid phase and a solid phase without requiring a complete discharge of a thermal reservoir between phase changes. In one embodiment, a cube filled with water and a gas or liquid within the horizontal tubing is used to charge the system, thereby freezing the water. The vertical tubing is then used to recover the energy by melting the ice, which is used for air conditioning. In one embodiment, copper tubing and fins are used to efficiently charge and discharge the system.

摘要： A heat exchange system for a turbomachine includes a heat exchanger that has a support wall extending along a longitudinal direction L and a plurality of fins each extending along a radial direction from a radially external surface of the support wall. The heat exchanger further includes a first profiled wall arranged upstream from the fins and configured to guide and slow down the flow of air entering the heat exchanger through the fins. A second profiled wall is arranged downstream from the fins and configured to accelerate the flow of air leaving the heat exchanger. Each first and second profiled wall is attached to the support wall via support elements extending radially from the radially external surface.
