Water to Water Heat Exchanger
1. Water to Water Heat Exchanger Summary
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. The tubes may be straight or bent in the shape of a U, called U-tubes.
HI-SEA Marine's shell and tube heat exchangers can also be used for water to water heating or cooling. They are particularly ideal for use as jacket water heat exchanger, using water glycol mixtures cooled by raw sea water. If glycol or other corrosion inhibitors aren't available then Thermex heat exchangers can be supplied with copper shells or other materials upon request.
