IHX Tubes These tubes are a combination of Suction and Liquid tubes used in the A/C Lines. The hot liquid in the Liquid tube is cooled by the low temperature gas in the Suction tube thereby improving the performance of the A/C system around 10%. There are two types of IHX namely spiral inner tube type and channel outer tube type (with or without spiral). Most of the modern-day vehicles use this IHX tubes to increase the performance and to reduce the tube clutter in the engine compartment.
Condensor Manifolds These are Inlet & Outlet manifolds used in the construction of the Condenser Core which is normally mounted on the front side of the Radiator. The Condenser helps is cooling the liquid refrigerant using the outside ram air assisted by a cooling fan. These manifolds help in diverting the refrigerant in different passages (3/4/5 passes) by using baffles to increase the heat transfer area. Some of the manifolds have the receiver drier tanks attached to them to remove the moisture from the refrigerant.
