Aerocooling and battery cooling systems
The engine, whether the endothermic or the more modern electric, must operate within a precise temperature range in order to ensure maximum performance.
The main challenge when designing a cooling system is to be able to maintain the right temperature range and at the same time ensure high vehicle performance and safety.
In electric cars, the challenge is greater since the batteries, to ensure the highest performance and maximum service life, must be maintained at temperatures of about 15-30°C.
For this purpose, in some cases it is also necessary to provide for the installation of auxiliary heaters and chillers.
The proper functioning of the cooling system is critical not only for performance, but also for vehicle safety, as lithium-ion batteries, if overheated or improperly cooled, can be affected by the "thermal runaway" phenomenon, which can potentially result in the burning of the liquid electrolyte contained in the batteries, a highly flammable and difficult to extinguish material.
Currently, the machines typically have dual liquid- and air-fed cooling systems. The first system consists of several components that, working in synergy, manage the various coolant flows to maintain the temperature target during the various working phases of the car, from start-up to stress phases.
The second system, on the other hand, is used both to dynamically cool the fluid through radiators and fans and to cool the hottest areas of the vehicle, maintaining, in both cases, the right balance between aeorodynamics and vehicle reliability.
