Abstract
The previous study presented during the last VTMS 4 showed the following results, for all engine cooling system and depending on the vehicles:
- Cost reduction by - 10 to -15%,
- Weight reduction by -15 to - 21%,
- Coolant volume reduction by -25%
- Fuel consumption by -3%,
- Thermal comfort improvement.
Despite of these good results, most of car manufacturers hesitated to use this new concept due to this technological breakthrough of engine cooling system because of expensive durability studies.
In this paper the electric fan has been simply suppressed and replaced by the heating blower allowing to cool the engine at idle and at low vehicle speed.
By suppressing the electric cooling fan, the advantages of this new economical engine cooling system become:
- cost reduction up to - 30%,
- weight reduction up to - 30%.
