Liquid to liquid
WCAC Twin Core
Customized Air to liquid cooled charge air coolers for demanding applications.
Air to liquid
LT Cooler
Specifically developed design for circuits using liquid coolant or low viscosity heat transfer fluids with working pressures up to 5 bar. High efficient fluid side dimple pattern and a louvered high efficient low height air side fin. Strong yet thin materials used throughout the cooler ensures lowest possible weight. Available in one to multi pass flow in S-configuration or a unique 3 pass back to front fluid flow giving an extra advantage at lower coolant and air speeds. Product can be designed and produced in line with specific customer specifications. Core depth ~50mm.
Technical requirements are derived in cooperation with the customer and in this process we can offer i.e:
- Heat rejection analysis.
- Coolant pressure drop and temperature field analysis using CFD.
- Forming simulation for manufacturability.
- Pulsation and vibration analysis
Product can be adapted and produced in line with specific OEM customer specifications.
