Heat Exchangers

Heat Exchangers

The basic principle of a heat exchanger (Shell & tube type) is the medium to be cooled (high temp. fluid) pass through the shell and cooling medium (Low temp. fluid) pass through the tubes. The heat is transferred from medium to be cooled to cooling medium. This high temp. fluid enters the shell through inlet nozzle and flows through the baffles according to the design / orientation and meets tubes and at this point the heat transfer occurs. By the time this fluid reaches the outlet nozzle the temp. would have come down to the required level. The cooling medium can be a refrigerant / chilled water or in marine applications - sea water.
