Definitions

  • the invention relates to a cooling apparatus suitable for cooling water, for example, the cooling water of a marine engine, comprising cooling pipes through which the cooling water is conducted, a pipe plate on which the cooling pipes are mounted, and a water header at the side of the pipe plate facing away from the cooling pipes, which water header has connecting stubs for inlet and out- let of the cooling water.
  • a cooling apparatus is a heat exchanger used on sea-going ships that have 5 to 10 megawatt-powered marine engines. Such ships have a length of between 30 and 150 metres. As a rule the cooling apparatus is used for cooling the cooling water of the marine engines. Of course, the cooling apparatus can also be employed for cooling water from another source. For the purpose of cooling, heat exchange takes place between the cooling fluid in the cooling apparatus of the marine engine and the surrounding seawater.
  • the cooling apparatus is mounted in a cavity in a special watertight space behind the ship's hull.
  • the ship's hull is provided with inlet and outlet openings to allow the seawater access to the cooling apparatus.
  • the pipe plate plays an important role in the cooling apparatus. Said pipe plate has a number of functions, such as
  • the cooling apparatus as such and its parts such as the pipe plate have to comply with strict requirements.
  • the desired mechanical life of the cooling appara- tus is 20 years and this also applies to the pipe plate. This mechanical life corresponds with that of the ship in which the cooling apparatus is installed. Consequently the cooling apparatus is sold as a maintenance-free product. This means that the occurrence of unforeseen maintenance is not permitted, whereas customary planned maintenance may take place. This takes place when the ship is docked.
  • the cooling apparatus and the pipe plate have an important safety function. As mentioned above, the cooling apparatus is located behind a cavity in the ship's hull. This means that the cooling apparatus must be leak-proof at all times, including under conditions of fire and in the presence of corrosive liquids and gases.
  • the pipe plate of the cooling apparatus is subjected to considerable stress.
  • the pipe plate has to be able to withstand all thermomechani- cal stresses; short-term (stationery, blow, impact, vibrations) , long-term (creep, stress relaxation) , thermal stresses and thermal shock.
  • the thermal limits are determined, among other things, by thermal safety measures ap- plied to the marine engine itself.
  • the cost price of the known cooler (price level 1999) is from about NLG 2,500 for the smallest model to NLG 40,000 for the larger models.
  • the known cooling apparatus and its integral parts such as cooling pipes, pipe plate and water header, are made of metal, is a problem.
  • the cooling pipes and pipe plate are substantially made of a copper alloy. This results in the problem that the mounted cool- ing apparatus causes corrosion problems due to contact potentials .
  • the aims of the invention may be realized with a cooling apparatus whose pipe plate is made of plastic.
  • the plastic has a load-bearing capacity of up to 6 bars overpressure at a temperature ranging from -20°C to +100°C. In this way the load requirements occurring in practice can be met, while in addition the load-bearing capacity of the plastic pipe plate is maintained during the entire mechanical life of the cooling apparatus .
  • the pipe plate and the water header form a whole.
  • the cost price of the cooling apparatus embodied with the plastic pipe plate is already reduced by approximately 20-30%. This cost price may be further reduced by means of the measure just mentioned.
  • Figure 1 shows as silhouette a ship 1, and in detail a cross section of a cooling apparatus mounted in the ship. It is a ship of the type discussed above, namely with a length between 30 and 150 metres and provided with a 5 to 10 megawatt-powered engine.
  • a cooling apparatus 3 is installed in the ship's side, approximately in the circle 2, a cooling apparatus 3 is installed. Said cooling apparatus 3 is mounted in a space behind the ship's hull 6, made water-tight by means of partition plates 4 and 5. Via the openings 7 and 8, the space delimited by the partition plates 4 and 5 and the ship's hull 6, is freely accessible to seawater.
  • the cooling apparatus 3 has connection stumps 9 and 10 for the supply or discharge of cooling water to the marine engine (not shown) .
  • Said connection stumps 9 and 10 form part of a water header 11, which is in commu- nication with a pipe plate 12.
  • On the said pipe plate 12 the cooling pipes 13 are mounted, through which flows the cooling water of the marine engine, supplied and discharged via the connection stumps 9 and 10.
  • the pipe plate 12 is made of plastic, which preferably has a load-bearing capacity of up to 6 bars in a temperature range from -20°C to +100°C. Due to its plastic embodiment, said pipe plate 12 provides a galvanic separation between the ship 1 on one hand and the coil of cooling pipes 13 on the other hand, thereby safeguarding said cooling pipes against cor- rosion problems.
  • the pipe plate 12 and the water header 11 are designed such as to form a whole.
  • the cooling apparatus 3 is provided with a substantially copper-comprising element which, when the cooling apparatus 3 is installed in a ship, can be adjusted to an anodic po- tential. This latter feature effectively combats fouling of the cooling apparatus, thereby ensuring that a high level of cooling power is maintained.
