Radiator Performance Testing

Calorimetric Radiator Testing

Young Calibration’s Radiator Calorimetric Test Facility offers thermal performance characterisation for automotive, marine and industrial heat exchangers worldwide. Although the facility is predominantly aimed at the passenger car market, the wind tunnel and plant can cover low temperature/ low flow coolers, high performance passenger cars and up to medium-size truck installations.

Radiator Testing Facilities

Extensive capabilities exist within the laboratory to cover radiators, cab heaters, low temperature radiators and industrial coolers.

Coolant Side Specification
  • Flow 1 – 400 lpm
  • Pressure < 2 bar dP
  • Temperature 40-95°C
  • Fluids: Water or 50/50 Antifreeze Mix
Cooling Air Side Specification
  • Size 900 x 800 mm
  • Flow 30 – 4000 l/s
  • Face Velocity 1 – 15 m/s
  • Pressure 10 – 5000 Pa
  • Temp 20 – 35 ±1°C
Calorimetric Radiator Testing

Detailed test reports present all the data in both tabular and graphical formats, covering air-side pressure drop, coolant side pressure drop, heat rejection performance, heat dissipation and individual measurement uncertainty statements.



Radiator Performance Testing
Recent Testing Projetcs
Previous testing programmes have included:

• CFD Model validation
• Thermal Imaging
• Production line sensitivity
• Cooler Pack Assessment
• Racecar Cooling Duct Development
• Benchmarking Exercises

The company operates two calorimetric test rigs, both of which can undertake radiator heat exchanger testing. The open outlet designed tunnel has the facility to run either, water or 50:50 antifreeze fluids, and has an increased airside capability upto 5000 Pa. This increased pressure capability allows for the testing of vehicle front end modules and single seater racecar monocoques to be installed within the tunnel.

We continue to serve a variety of industries, including; military, Formula 1, NASCAR, aerospace, Combined Heat & Power (CHP) applications and more recently Fuel Cell integration companies.
