Automotive Coolant Test Loop for Radiator Pressure Drop and Flow Distribution Testing
Drawing preview
The scenario

An automotive test rig requires a coolant circulation loop to evaluate radiator performance by measuring pressure drop across the radiator and flow distribution through the system.

What is in this drawing

Read the decisions behind it.

01

Use hx_air_cooled for the radiator as a liquid-to-air heat exchanger

02

Measure differential pressure with PT-101 and PT-102 feeding PDI-101

03

Control flow rate with FT-101 and FIC-101 on a diaphragm-operated control valve

Reuse for any liquid cooling loop test bench where heat exchanger pressure drop and flow characteristics need to be evaluated.
