Abstract
A heat exchanger for cooling a liquid comprising a cavity (2) containing a refrigerating liquid capable of evaporation under the effect of a depression maintained by a pump. The cavity includes at least a first wall (21) in contact with the liquid to be cooled, the first wall (21) being substantially conical such that its cross-sectional surface tapers from the base towards the top, and at least a second wall (22) forming the base of the conical shape and incorporating communication (30) between the cavity (2) of the exchanger and the pump.
