As part of the engine cooling system, fan systems include a fan system motor, a blade and a shroud.
Electrification and new ICE require greater fan system power and therefore higher energy consumption that generate higher noise levels.
Blade and shroud design have been improved to optimize acoustics and efficiency whilst light and compact brushless motors provide maximum airflow at minimized noise levels for powertrain/battery cooling, with best-in-class efficiency.
EVs coolant hub architectures with several coolant loops (cabin heater/battery/power electronics) have a high degree of complexity, in particular for vehicles equipped with a Heat Pump system. In order to increase the vehicle’s driving range, the pressure drops and thus the electrical power consumption of the water pump must be reduced.
Smart Coolant Modules are subsystems that can be customized to meet specific customer requirements. They must therefore be compatible with most of BEVs Thermal Management Systems including Direct and Indirect Heat Pumps.
BEVs often have a thin air inlet located at the bottom of the front end while the cooling needs remain high and acoustic constraints are severe. Minimizing the electrical consumption is also key to stabilizing the vehicle’s range. To address these constraits, Valeo has developped tilted cooling modules as well as an ultra flat cooling module at 210 mm in the Z axis.
Located in the front cooling module, air conditioning condensers are heat exchangers that are part of the refrigerant loop (A/C system). When going through this type of exchangers, the refrigerant becomes liquid, or put differently “condenses”, to release the heat it carries in the air that crosses the exchanger.
In R-744 A/C & heat pump systems, gas coolers have exactly the same function.
A/C Condensers can sometimes include an evaporation function – they are the called “evaporative-condensers”. Evaporators are exchangers that provide cold air while drying the air that goes through it to demist the windshield.
Located in the front cooling module, radiators are part of the cooling system.
They can be used in cooling or heating mode depending on the cooling loop (with or without heat pump).
Valeo radiators are designed for vehicles with combustion, hybrid and full electric engines. The purpose of a car radiator is to improve cooling performance and reduce energy consumption.
