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： A heat exchanger includes an inlet header, an outlet header and a plurality of flat, multi-channel heat exchange tubes extending therebetween. A longitudinally extending member divides the interior of the header into a first chamber on one side thereof for receiving a fluid and a second chamber on the other side thereof. A plurality of multi-channel heat exchange tubes extend between the headers with the respective inlet end of each heat exchange tube passing into the second chamber of the inlet header. Fluid passes through a series of longitudinally spaced openings in the longitudinally extending member for distribution to the inlets to the channels of the multi-channel heat exchange tubes. The fluid may undergo expansion as it passes through the openings.

摘要： A heat exchanger includes a plurality of flat, multi-channel heat exchange tubes extending between spaced headers. Each heat exchange tube has an inlet end in fluid flow communication with one of the headers and an outlet opening to the other header. Each heat exchange tube has a plurality of flow channels extending longitudinally in parallel relationship from its inlet end to its outlet end. A plurality of connectors are positioned between the inlet header and the heat transfer tubes to define a flow path providing fluid flow communication between the inlet header and the inlet ends of the heat exchange tubes. Two or more flow restriction ports are arranged in the series in the flow path through each connector whereby fluid flowing from the inlet header to the flow channels of the heat exchange tube associated therewith undergoes an expansion as the fluid passes through each flow restriction port.

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.
