Heat exchangers can be used for a wide variety of uses. As the name implies, these can be used for heating as well as cooling. The two primary types of marine heat exchangers used aboard vessels in the maritime industry are plate, and shell and tube. Maintenance for heat exchangers prevents fouling and galvanic corrosion from dissimilar metals.
Marine engines and some stationary engines have ready access to a large volume of water at a suitable temperature. The water may be used directly to cool the engine, but often has sediment, which can clog coolant passages, or chemicals, such as salt which can chemically damage the engine. Thus, engine coolant may be run through a heat exchanger ...
Tubular heat exchanger Partial view into inlet plenum of shell and tube heat exchanger of a refrigerant based chiller for providing air-conditioning to a building. A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. [1]
The study concluded that although microbial fouling was an issue for the warm surface water heat exchanger, the cold water heat exchanger suffered little or no biofouling and only minimal inorganic fouling. [46] Besides water temperature, microbial fouling also depends on nutrient levels, with growth occurring faster in nutrient rich water. [113]
Types of recuperator, or cross plate heat exchanger. A recuperator is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat. Generally, they are used to extract heat from ...
A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids.This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids are spread out over the plates.
Outboards manufactured by Seven Marine use a closed-loop cooling system with a heat exchanger. This means saltwater is not pumped through the engine block, as is the case with most outboard motors, but instead engine coolant and outside water are pumped through (opposite sides of) the heat exchanger.
Exhaust heat management helps reduce exhaust heat radiating from the exhaust pipe and components. One dominant solution to aftermarket upgrades is the use of a ceramic coating applied via thermal spraying as a heat shield. This not only reduces heat loss and lessens back pressure, but also provides an effective way to protect the exhaust system ...
