Abstract (en)
[origin: CN110382977A] A refrigerant condenser having multiple sections of straight tubes terminating in segmented headers, each subsequent section having an overall cross-sectional area less than an initial section with the overall cross section of the initial section large enough to substantially reduce vapor velocity thus reducing the refrigerant pressure drop; the total cross-sectional area dimensioned to cause entrance vapor velocity, to be sufficient to establish an internal film heat transfer coefficient greater than the external heat transfer coefficient while limiting the internal pressure drop for the heatrejection intended.
