Baudelot cooler

The extended flat face may be used for air cooling, for liquid cooling if immersed in a tank, or as a Baudelot cooler. 

I. Baudelot coolers (see Figures 7.7 and 7.8a). The evaporator stands above a collection tank, and the water runs down the outside surface in a thin layer. Evaporator construction can be pipe coils or embossed plates. The latter are now usually of stainless steel, to avoid corrosion troubles. Evaporators maybe flooded or dry expansion. During operation, a Baudelot cooler... 

Chilling of brines for pre-cooling will generally be in shell-and-tube evaporators. The Baudelot cooler within the pressure vessel may be cooled by flooded or dry expansion refrigerant, or by brine. 

BAUDELOT COOLER - Heat exchanger in which water flows by gravity over the outside of the tubes or plates.
