Product Features : –
Two types of heat exchanger are used to cool hydraulic oil: (1) shell-and-tube and (2) finned tube. The shell-and-tube heat exchanger has a series of tubes inside a closed cylinder. The oil flows through the small tubes, and the fluid receiving the heat (typically water) flows around the small tubes. Routing of the oil can be done to produce a single pass (oil enters one end and exits the other end) or a double pass (oil enters one end, makes a u-turn at the other end, and travels back to exit at the same end it entered).

Above is typically a shell and tube-type heat exchanger. The cooling water is pumped into the heat exchanger and flows around the tube bank. The hydraulic fluid, which is to be cooled, flows through the tubes. While flowing through the tubes, the fluid gives away heat to the water, thereby reducing its temperature.
Advantages of water-cooled heat exchanger are : –

1. They are very compact and cost-effective

2. They do not make noise

3. They are good in dirty environments.

Shell-and-Tube Heat Exchangers Construction Details

The shell-and-tube heat exchanger is named for its two major components – round tubes mounted inside a cylindrical shell.

The shell cylinder can be fabricated from rolled plate or from piping (up to 24 inch diameters).  The tubes are thin-walled tubing produced specifically for use in heat exchangers.

Tubes  

Tubing may be seamless or welded.  Seamless tubing is produced in an extrusion process; welded tubing is produced by rolling a strip into a cylinder and welding the seam.  Welded tubing is usually more economical.

Normal tube diameters are 5/8 inch, 3/4 inch and 1 inch.  Tubes of smaller diameter can be used but they are more difficult to clean mechanically.  Tubes of larger diameter are sometimes used either to facilitate mechanical cleaning or to achieve lower pressure drop.

The normal tube wall thickness ranges from 12 to 16 BWG (from 0.109 inches to 0.065 inches thick).  Tubes with thinner walls (18 to 20 BWG) are used when the tubing material is relatively expensive such as titanium.

Tubing may be finned to provide more heat transfer surface; finning is more common on the outside of the tubes, but is also available on the inside of the tubes.  High flux tubes are tubing with special surface to enhance heat transfer on either or both sides of the tube wall.  Inserts such as twisted tapes can be installed inside tubes to improve heat transfer especially when handling viscous fluids in laminar flow conditions.  Twisted tubes are also available.  These tubes can provide enhanced heat transfer in certain applications.

Typical Applications 
              
The shell-and-tube heat exchanger is by far the most common type of heat exchanger used in industry.  It can be fabricated from a wide range of materials both metallic and non-metallic. Design pressures range from full vacuum to 6,000 psi.  Design temperatures range from -250oC to 800oC.  Shell-and-tube heat exchangers can be used in almost all process heat transfer applications.
The shell-and-tube design is more rugged than other types of heat exchangers.  It can stand more (physical and process) abuse.  However, it may not be the most economical or most efficient selection especially for heat recovery applications or for highly viscous fluids.  The shell-and-tube heat exchanger will perform poorly with any temperature crosses unless multiple units in series are employed.
Typical applications include condensers, reboilers and process heaters and coolers.
