What are cross flow fans?
What are cross flow fans?
The cross flow fan (also called a tangential fan) is used extensively in the HVAC industry, as well as in electronics. It produces an even laminar airflow and allows horizontal or vertical mounting; in addition, a cross flow fan prevents the overheating of components.
Where are cross flow fans used?
Examples of use cases for cross flow fans include:
- Drying units.
- Air curtains.
- Melting machines.
- Transformer air cooling.
- Automotive air conditioning.
What is a tangential fan?
In a tangential fan, the air is drawn in over the entire length of the fan impeller. Inside the impeller, the airflow is diverted and accelerated by the vortex created by the rotation of the impeller. The airstream then exits over the entire length of the impeller on the discharge side.
How many types of axial flow fans are there?
The two most common types of industrial, Axial Flow Fans are Tube Axial Fans (or Ducted Fans) and Panel Fans or Wall Fans. Tube Axial Fans use a propeller, rotating in a round section of duct, which is mounted into ductwork of the same diameter to exhaust hot and/or contaminated air from a process or system.
How many types of fan are there?
There are three main types of fans used for moving air, axial, centrifugal (also called radial) and cross flow (also called tangential).
What is difference between centrifugal and axial fan?
An axial fan is one in which the extracted air is forced to move parallel to the shaft about which the blades rotate. Centrifugal fans extract air at right angles to the intake of the fan, and spin the air outwards to the outlet by deflection and centrifugal force.
How do centrifugal fans work?
Centrifugal fans rely on blades to drag air into a circular motion with centrifugal forces speeding up airflow radially and outwards. These fans move air outward thorough ducts or tubes, and they provide a stronger and more stable air flow than axial fans do.
Where is a tangential fan used?
These days tangential fans can be used for a number of applications including: air curtains, blowers for electrical resistance heaters (Electric Fires / Kick space heaters), skin cooling for ovens amongst others.
