Abstract
In a parallel flow heat exchanger, which is susceptible to having a non-uniform distribution of a two-phase refrigerant flow to the individual channels, the resultant differences in the refrigerant flow therethrough are compensated and counter-balanced by a corresponding difference in the external heat transfer rate for the respective channels. In one embodiment, these differences are accomplished by variable characteristics of extended heat transfer surface elements such as fin type, fin density, fin geometry and difference in construction materials, and in another embodiment, by varying the airflow distribution over the cross-section area of the heat exchanger.
