SEAWATER HEAT EXCHANGER OF CLOSED COOLING CIRCUIT - APPLICATION OF SAME IN SEA ENGINES

摘要

Novelty: Prompt and efficient heat exchange via sea water in sea engines. Technical features: Heat exchange is due to the differential course of the cooling liquid through the flow reflectors-diaphragms (2) and the counter-flow inlet and outlet of the cooling liquid and sea water (fig.1-A1,A2, B1, B2). The construction in question becomes resistant to electrolysis-induced erosion thanks to anodes (4) placed at the sea water seal (5) and the cooling liquid replenishment-storage recipient (7) of the engine as well as to the construction which is completely made of stainless steel 316L. Furthermore,the dismounting of the scanty tubes of the dismountable cell (14) facilitates the potential replacement of any tube (12) but not the thorough replacement of the cell. Advantages: Faster visual control and cleaning due to the dismountable scanty structure of the cell's tube; facility in connecting the inlet and outlet tubes of the seawater and cooling liquid in restricted areas of the engine by utilisation of rotary angular tubes (8) serving for the inlet and discharge of same as to the desired place.
