Marine Heat Exchanger
1. Marine Heat Exchanger Summary
A heat exchanger is a device used to transfer heat between two or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.
The HI-SEA Marine's shell and tube heat exchanger range includes hydraulic oil coolers, marine oil coolers, charge air coolers and swimming pool heat exchangers, all of which feature a fully floating tube bundle designed to prevent fatigue from thermal expansion and improve serviceability. In addition to this, our heat exchangers are fitted with twin seals and witness rings as standard to provide maximum protection against cross fluid contamination.
2. Advantages of Marine Heat Exchanger
Our shell and tube heat exchangers are designed to be as flexible as possible. By changing the materials of the headers and tubes, the heat exchangers can be used in fresh water and marine environments. We can also adjust the number of fluid passes on both circuits ensuring that the heat exchanger can perform at its most optimal level before increasing the size. This can improve efficiency and reduce costs for our customers. For more specialist requirements however we can design shell and tube heat exchangers with unique characteristics making them a perfect fit for your equipment.
3. Composition of Marine Heat Exchanger
Shell and tube heat exchangers consist of series of tubes. One set of these tubes contains the fluid that must be either heated or cooled. The second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required. A set of tubes is called the tube bundle and can be made up of several types of tubes: plain, longitudinally finned, etc. Shell and tube heat exchangers are typically used for high-pressure applications (with pressures greater than 30 bar and temperatures greater than 260 °C). This is because the shell and tube heat exchangers are robust due to their shape.
Several thermal design features must be considered when designing the tubes in the shell and tube heat exchangers: There can be many variations on the shell and tube design. Typically, the ends of each tube are connected to plenums (sometimes called water boxes) through holes in tubesheets.
