A quench cooler or transferline heat exchanger for quenching the effluent from a cracking furnace has an inlet coupling between the cracking furnace tubes and the tubes of the quench cooler which splits the flow into a plurality of branches. The flow passages are configured to initially decelerate and then reaccelerate the gas. This involves a conical diverging diffuser section and then a tapered and branched converging section. The cross sectional transitions are smooth to avoid dead spaces and minimize pressure loss.
