Title:
PARALLEL FLOW EVAPORATOR WITH VARIABLE CHANNEL INSERTION DEPTH
Document Type and Number:
WIPO Patent Application WO2006055297
Kind Code:
A3
Abstract:
In a parallel flow heat exchanger having an inlet manifold connected to a plurality of parallel channels, the degree of insertion depth of the parallel channels into the inlet manifold is variable so as to adjust the impedance to the refrigerant flow into the individual channels. The degree of insertion depth is progressively reduced toward a downstream end of the manifold for the individual channels or for the channel sections. The diameter of the inlet manifold is locally increased or its cross-section area altered in order to accommodate the flow of refrigerant around the tube insertions. Similar technique is applied to the outlet manifold as well to further balance hydraulic resistances.
