Thermal Management overview

Thermal management refers to energetically optimizing the thermal balance in a vehicle. A thermal management system involves controlling temperature through technology. This technology is based on thermodynamics and heat transfer.
Thermal management is a wide-ranging term covering various forms of heat transfer, including conduction, convection, and radiation, involving different processes.

In the automotive industry, thermal management is necessary for protecting and insulating batteries.
Battery cooling system´s performance is crucial for BEV, HEV, PHEV, and FCEV vehicles, a proper design of the cooling system can provide real answers to key challenges related to:​

• Durability of battery
• Vehicle performance
• Fast recharging ​
• Range ​

New solutions needed for advanced battery cooling in innovative systems specifying new hydraulic requirements:

• heat transfer from battery cell/module to coolant, heat transfer within the system, heat sink

• solutions for better heat transfer from battery to coolant:

a) immersive cooling with dielectric coolant & different viscosity

b) improved geometry in cooling plates

c) higher flow rate in the system to increase heat transfer from source to sink

d) “Coolant on Demand Strategy” connecting coolant and refrigerant systems

Thermal Management system

Cooling pumps for thermal management and for EV fast charging are key components to supply coolant on-demand for critical thermal management systems. By cooling the engine precisely and only as required, cooling pumps reduce fuel consumption with the additional benefit of curbing friction losses and emissions.

Traditional water pumps such as centrifugal pumps are characterized by one single BOP so the request of "Coolant on Demand" and "Fast Charging" requires an increase of the number of traditional pumps to satisfy multiple coolant circuits; a more efficient pump like Positive Displacement can reduce the number of pumps.

The future could be represented by the technology of positive displacement volumetric pumps which could play a better role as cooling pumps for these systems with the following main advantages:

• Robust design​
• High Efficiency​
• Suitable for high pressure and high flow​
• Low Noise​
• Tolerant to abrasive particles​
• Easy assembly​
• Multiple BOP (Best operating Point) due to a variable speed
