Abstract
A liquid distributor delivers a falling flow of the liquid to be distributed substantially uniformly along a longitudinal extent of the liquid distributor. The liquid distributor has a bottom wall including a longitudinally extending distribution plate having a plurality of laterally spaced and longitudinally extending channels. A shell and tube evaporator for chilling a working fluid incorporates the liquid distributor as a distributor of liquid onto the heat exchange tubes of a tube bundle disposed within an interior volume of the shell. Each channel is aligned with a respective column of the plurality of vertical columns of heat exchange tubes and is configured to deliver a falling flow of liquid refrigerant onto the respective tube column substantially uniformly along the longitudinal extent of the respective tube column.
