Minerva Cooling Systems wanted to carry out several series of tests, particularly on the air and water-cooled plate ranges designed by the Design Office or designed by customers in order to qualify their ability to evacuate calories through their cooling circuits.
This bench is now used to quickly qualify cooling assemblies through the thermal (and hydraulic) spectrum under real conditions and complements software simulations.
It is thermally insulated and controlled by a Siemens cabinet and industrial acquisition PC. A touch screen is used to control the bench and view the data received immediately.
For water-cooled plates:
Entry parameters
- Controlled fluid cooling, 120L tank.
- 1 to 10 bar pressure pump and 60l/min flow rate
- Pressure and rate inspection
- Cooling temperature inspection
Measures traced
- Temperature under electronic components (IGBT for example)
- Fluid entry and exit temperature in the plate
- Entry and exit pressures and flow rates
For the air-cooled plates:
Entry parameters
- Air cooling at a maximum rate of 10m/s
- Frequency variation flow rate adjustment
- Pressure, speed and temperature variation
- Entry and exit air temperature inspection
Measures traced
- Temperature under components
- Upstream and downstream air entry temperature
- Upstream and downstream air pressure and speed
Pulsed pressure inspection for the water plates:
Also called the "pull test". In this case, the bench applies a pulsed pressure that may be adjusted from 0 to 10 bars to the water plates for a pressure increase and lowering cycle of a few seconds.
Additional tests:
Minerva Cooling Systems also manages the following for its customers with approved laboratories
- Impact and vibration qualifications according to standard CEI 61373
- Saline mist corrosion resistance tests
- Rapid temperature variation tests
- 3D thermal exchange test bench
