摘要： A heat exchanger includes a plurality of multi-channel heat exchange tubes extending between spaced inlet and outlet headers. Each heat exchange tube has a plurality of flow channels defining discrete flow paths extending longitudinally in parallel relationship from its inlet end to its outlet end. The inlet header has a channel for receiving a two-phase fluid from a fluid circuit and a chamber for collecting the fluid. The chamber has an inlet in flow communication with the channel and an outlet in flow communication with the plurality of fluid flow paths of the heat exchange tubes. The channel defines a relatively high turbulence flow passage that induces uniform mixing of the liquid phase refrigerant and the vapor phase fluid and reduces potential stratification of the vapor phase and the liquid phase within the fluid passing through the header.

摘要： A comb-like insert having a body and plurality of tapered fingers is installed with its fingers disposed within respective minichannels. The fingers and their respective minichannels are so sized as to restrict the channels and frictionally hold the insert in place in one dimension while providing for gaps in another dimension such that the flow of refrigerant is somewhat obstructed but allowed to pass through the gaps between the insert fingers and the minichannel walls and then expand as it passes along the tapered fingers to thereby provide a more homogenous mixture to the individual minichannels. A provision is also made to hold the insert in its installed position by way of internal structure within the inlet manifold. In one embodiment, an internal plate is provided for that purpose, and the plate has openings formed therein for the equalization of pressure on either side thereof.

摘要： The present invention is directed to a method of reducing cooling capacity in a rotary vane compressor in such a way that the power requirement to drive the rotor is reduced to the same extent (or close to) as capacity is reduced. An economizer port operating in economizing and unloading cycles is located in the compression region at a point after the compression chamber has been closed for the compression and at a point where sufficient both unloading (reducing) and economizing (increasing) capacities are provided. A valve is associated with the economizer port, the valve body being formed from a part of the stator body. A seat of the valve in the closed position is shaped to be contiguous with the wall portion of the stator. In an opened position the valve provides conmumnication between the compression chamber and an external portion of the economizer port.
