- FIG. 6 shows a section through the heat exchanger (2) along the line A-A in Fig. 2.
- sea water is through the Cooling medium inlet (14) introduced into the heat exchanger chamber (3.1).
- the heat exchanger chamber (3.1) is by means of a medium separating plate (10.1) that passes through the pipes (4.1) is closed. A contact of sea water and the charge air is thus avoided.
- the charge air is through the charge air inlet (5.1) introduced and flows around the sea water transporting pipes 4.1, whereby the charge air (7.1) to to the charge air outlet (6.1) is cooled because the heat is transferred to the Sea water is released.
- the sea water flows into the cover (21) of the heat exchanger cover (12) and is arranged by the in the lid (12) Flow channel (22) passed into the cover (23).
- the lake water flows through the heat exchanger chamber (3.2) to the Cool the fuel (7.2).
- the sea water enters the cover (15) of the heat exchanger cover (11) and flows into the Cover (19) by means of the division of the cover (17) of the baffle (18) is formed.
