Setrab Intercooler Performance Estimation
Finding the right size of intercooler or determining the input data for dimensioning can be challenging. Enter your vehicle data below to estimate the performance of particular size of intercooler.
Please note that the program below provides an estimation of expected performance. Actual performance will depend on a multitude of variables, e.g. installation, actual air flow through cooler, tank design, etc.
Cooling air face velocity
The table below can be used to estimate the air speed through the cooler depending on vehicle speed and inlet size.
| m/s (Va) | ||||||
| Vvehicle | Vvehicle | Vvehicle | Front inlet area size in % of cooler area | |||
| m/s | km/h | mph | 30% | 50% | 70% | 100% |
| 13.9 | 50 | 31 | 2.1 | 2.2 | 2.3 | 2.4 |
| 27.8 | 100 | 62 | 4.7 | 5.4 | 5.6 | 5.7 |
| 41.7 | 150 | 93 | 7.3 | 8.2 | 8.5 | 8.7 |
| 55.6 | 200 | 124 | 9.7 | 10.9 | 11.4 | 11.7 |
| 69.4 | 250 | 155 | 12 | 13.6 | 14.2 | 14.5 |
| 83.3 | 300 | 185 | 14.3 | 16.3 | 16.9 | 17.3 |
For example, if vehicle speed is 150 km/h and the relation between front air inlet opening and the charge cooler area is 50% you will have roughly 8.2 m/s cooling air face velocity.
The cooling air face velocity is on average 15-18% of vehicle speed in the table above. These values can be better or worse depending on intercooler installation in the vehicle and vehicle aerodynamics.
We hope you find this feature useful and we would be happy to receive your feedback to help us develop it further.
