概要

The Free and Forced Convection Heat Transfer Unit, "TCLFB", allows to study the efficiency ofdifferent exchangers, analyzing the heat transmission coefficients of each exchanger exposedto different airflows.

Fan placed in the upper part of the tunnel allows controlling the airflow that goes through thetunnel.

Electronic console contains the control circuits to measure temperatures, electrical control,electrical supply and speed control of the fan.

The airflow is measured with a flow sensor set at the inferior part of the tunnel.

This unit allows making a study of the heat transmission in three different types of exchangers:

  • Flat exchanger.
  • Pins exchanger.
  • Fins exchanger.
