Vehicle Thermal Management

Vehicle Thermal Management<

There are multiple sub-systems in the mobility in which a highly complex and inter-dependent heat transfer takes place. Designers ought to know the heat transfer mechanism from one sub- system to another for designing vehicles for low energy consumption and thermal comfort of the passengers. 1D System & 3D CFD simulations thus become vital for the vehicle thermal management. 1D- 3D co-simulation are often employed for simulating different operating parameters of the different systems.

ESPL regularly supports our OEM customers in the vehicle thermal management domain. As the simulations required to be carried out at Full Vehicle level, understanding of system engineering requirements and a high-tech infrastructure form the basis. HPC cluster and multi- CPU licenses at our setup are capable of solving massively sized simulations within few hours to serve our customers in timely manner.

Underhood Thermal Management

Underhood area of any vehicle is one of the most complex assemblies of radiator, engine, coolant circuit, radiator, oil cooler, condenser, hoses, cables, surge tank, battery, sub-frame and many more parts. Packaging of all the parts from functional requirements, assembling while production and future maintenance requirements is not anyone’s cup of tea, On top of that, underhood is the most critical region for the thermal management. Designers have to fight against limited space for effective cooling of engines, optimizing HVAC performance and controlling heat transfer from underhood to passenger compartment.

After working on multiple underhood simulations, we had developed an optimized method based on Part based modelling approach and tried to reduce complications for customers. Our method with a systematic way for defining well- assigned interfaces and part labelling system, new variants of the underhood models can be built at significantly lower time.

Imagine your car parked throughout the coldest sub-zero winter night and started on the next morning. We can simulate the thermal shock experienced by your car within the first few minutes of engine starting. Interesting. Isn’t it?

EV Thermal Management & HVAC Systems

EV thermal management is a vehicle integration task. Compared to traditional IC engine underhood area, the complexities in case of EVs are lesser. However EV thermal management comes with new challenges like efficient and silent HVAC systems, optimized pump performance for the coolant. All the challenges can be simulated much in advance with the implementation of CAE.
