Smart microelectronics from Infineon help meet thermal management challenges and increase the efficiency of cooling and HVAC systems
Modern vehicles increasingly rely on microelectronic components. This applies in particular to powertrain applications like electric pumps, including fuel, oil and water pumps, and fans such as HVAC blowers, engine cooling and battery cooling fans.
Due to their proximity to the engine, motor control solutions for automotive pumps and fans must be extremely robust and able to withstand high temperatures. Additionally, car manufacturers are challenged to accommodate a rising number of auxiliary pumps in a limited space.
Pumps
Enhanced motor control efficiency is one of the key success factors in pump design. Infineon’s cost- and system-optimized solutions, boasting a high level of integration, are all geared towards maximizing efficiency, especially those designed for BLDC motor control.
Auxiliary pumps and fans, such as water and oil pumps as well as engine and battery cooling fans, are exposed to high temperatures. Further design challenges for these applications include the need to increase electrical efficiency, minimize acoustic noise and overcome space constraints. Infineon’s highly integrated Embedded Power ICs master these challenges with ease.
A fuel pump runs continuously and is often positioned below the rear seat, where it has limited cooling capabilities. So ECU cooling presents its own design challenges. Infineon’s cost- and system-optimized NovalithIC™ solutions are the perfect fit for fuel pumps due to their high level of reliability.
Engine/Battery Cooling Fans
The engine/battery cooling fan is one of the main thermal management components in the engine compartment. Powerful cooling fans are key to meeting rising demand for greater fuel efficiency and longer ranges for electric vehicles. One way of extending range, for example, is by maintaining a stable thermal environment around batteries.
