Abstract (en)
The invention concerns a heat exchanger for exchanging heat between a first fluid flow generated by pumping fluid through a ship's engine and/or other heat generating equipment and through a cooling channel (11,12,13) and a second fluid flow generated by a ship's propeller (3) and the ship's speed comprising a nozzle surrounding the ship's propeller (3) having an outer wall (16) that forms an outside surface (6) of the nozzle and an inner wall (17) that forms an inside surface (4) of the nozzle and the outer wall (16) and the inner wall (17) form a cooling surface between the first fluid flow and the second fluid flow over approximately the whole perimeter of the nozzle. In accordance with the invention, the cooling surface area is approximately constant along the length of the cooling channel (11,12,13) in the nozzle.
