The key differences between stacked evaporators and manifold evaporators in car air conditioning systems lie in their structural design, refrigerant flow, and resulting performance characteristics. Stacked Evaporator Stacked-Evaporator Structural Characteristics: A stacked evaporator typically consists of multiple flat, layered heat exchange passages (or primary heat sinks). Heat exchange fins are placed between adjacent layers to increase the heat transfer surface area. The refrigerant flows through these stacked passages either in series or in parallel, connected by ports. Internal structures like flow equalization holes, flow restrictor fins, or internal fins might be present to ensure even refrigerant distribution. Working Principle: The...
