DEVICE FOR HEATING LIQUIDS IN THE FIELD OF MEDICAL APPLICATIONS

摘要

A device for heating liquids has a cylindrical heat exchanger (10) having a groove (18) on the outside to take a pipe (20) through which the liquid flows. The groove (18) forms turns (w) with a heat transfer length (l) per turn (w). For a given longitudinal section (L) of the pipe (20), the heat transfer length (l) per turn (w) is increased by a factor of 1.4 or the heat exchange cylinder (10) is arranged substantially horizontally and the diameter of the heat exchanger (10) is greater than or equal to 160 mm.
