Cross Flow Heat Exchanger- Engineering Lab Training Systems Description and Specifications for Lab Tenders
Cross Flow Heat Exchanger- Engineering Lab Training Systems.
Technical Description
The benchtop unit mainly
comprises a vertical air duct. A fan draws the air through the duct.
Interchangeable heaters dissipate heat directly into the airflow. The
following heater elements are included: pipe, pipe bundle and finned
pipe. To investigate the effect of the flow in the pipe bundle, the
heater insert can be positioned in different pipe rows. Electronic
sensors are used to take measurements. The measured values are indicated
digitally on the display unit and transferred directly to a PC. A data
acquisition card for the PC with easy to use software is included. The
software enables, among other aspects, the measured data to be recorded
and stored. The flow rate, Reynolds and Nusselt numbers are calculated,
temperature-time relation and the dependence of the Nusselt number on
the Reynolds number can be demonstrated graphically.
