TH-3111B Concentric Tube Heat Exchanger

This exchanger allow us to measure cold water and hot water temperatures in different points of the exchanger.

  • Anodized aluminium structure and panels in HDF.
  • All the water contact parts are made of PVC, Brass, Copper or Stainless Steel to avoid corrosion.
  • Diagram in the front panel with similar distribution to the elements in the real unit.
  • Formed by two copper concentric tubes with hot water circulating through the internal tube and cold water circulating through the annular space.
  • Exchange length: L x 4 x 0.5 = 2m.

 

Internal tube

  • Internal diameter: 8mm
  • External diameter: 10mm
  • Thickness = 1mm
  • Internal heat transfer area: 0.0377 m2
  • External heat transfer area: 0.0471 m2

External tube

  • Internal diameter: 13~14mm
  • External diameter: 15~16mm
  • Thickness = 1~1.5mm

 Sensors

  • Temperature sensors (”K” type thermocouples).
  • Hot water sensor in the middle of the exchanger.
  • Cold water sensor in the middle of the exchanger.

Description

This unit is used for study the heat transfer through a concentric tube under parallel or counter flow conditions.

The Turbulent Flow Heat Exchanger allow us to study the heat transfer between hot water that circulates through an internal tube and cold water that flows through the annular zone between the internal an the external tubes. This exchanger allow us to measure cold water and hot water temperatures in different points of the exchanger.
