These are heat exchanging apparatuses intended both to cool and to preheat various fluids.
They have specific constructions, by which it is possible to be groupped, as follows:
- Heat exchangers TKH type-shell-and-tube construction with fixed tube plates and straight heat exchanging tubes.
- Heat exchangers KC tupe shell – and – tube construction in which the heat exchanging tubes are wound on serpentines.
- Heat exchangers СТТ type-construction consist of tube in tube wound on a serpentines.
- Heat exchangers KC8 type – it is not suitable to operate with sea and fresh water
The termal engineering and hydrodynamic characteristics depend on the parameters of the system in which they are included.
