Abstract:
Brazed-plates condenser, the condenser comprising a heat exchanger body which has at least one condensation passage for a condensing fluid flowing downward and containing low boiling constituents, said condensation passage being flat in shape and delimited between two substantially vertical parallel plates, said passage having a general plane, said passage containing, over most of its height, a heat-exchange spacer corrugation with substantially vertical generatrices; an inlet box for said fluid, said inlet box being located at the upper end of the passage; an outlet box for a liquid resulting from said condensation of said fluid except said low-boiling constituents, said outlet box being located at the bottom end of the passage and at a bottom end of the plates, said outlet box being connected to a liquid condensate outlet pipe and to a gas outlet pipe; an outlet distributor spacer corrugation having generatrices which are at an angle to the direction of the generatrices of the heat-exchange corrugation and which direct the liquid condensate from a bottom end of the heat-exchange corrugation to the outlet box, wherein, in cross section in said general plane, a part of the outlet box which leis between a lowermost point of said outlet box and a lowermost point of intersection of said liquid condensate outlet pipe and said outlet box, is entirely situated at a level that is lower than the level of a lowermost point of the distributor corrugation.
