The condensate and coolant are then collected at the bottom. The large surface place reached by the spray assures they are really productive heat exchangers.
The spiral exchangers, since the title indicates, have spiral bodies which can be made from two flat components, usually metal strips, which can be spiral to variety two channels.
In such a exchanger the tubesheet for the Rear Header stop will not be welded on the shell but permitted to go or float.
