DC motors and fans drive automotive
cooling
Automotive cooling applications provide a fast growing opportunity for the application of DC motors and ventilation modules.
The increasing power requirements of existing electronics and the increasing number of independent modular systems in automotive applications provide a fast growing opportunity for the application of DC motors and ventilation modules Sunon has developed a number of products for automotive applications, including cooling of electronic control units (ECUs)

Optimised CPU cooler outperforms Intel original
The design of the Aturbo CPU cooler is based on a well-proven air-cooling scheme with an improved base and fin blades.
Fans and blowers have the smallest of claims
Micro-miniature fans and blowers overcome strict space limitations to provide forced cross airflow in a micro-sized chassis.
In this application the cooling performance of the existing solution has been limited by the severs environmental conditions under the bonnet.
To make matters worse, the increasing sophistication of today's ECUs has drastically increased the heat generated.
Sunon has developed a "breakthrough design" fan that matches the future flow performance requirements and is capable of reliable operation in harsh environmental conditions with exposure to chemicals such as brake fluid, as well as high temperatures as high as 120C.
Inside the car, seat ventilation modules not only provide improved personal thermal comfort for passengers, but also reduce vehicle fuel consumption by cutting the demands on the main air conditioning system.
The challenges posed by this application include requirements for low levels of noise and vibration, high levels of dynamic stress as well as EMI/EMC limitations.
By initiating a new motor development, Sunon has provided advanced engineering support to meet the design and technical requirements of this new application from its concept phase to its production stage with the support and appreciation of tier one automotive customers.
The integration of a cooling fan in automotive infotainment applications is also crucial in meeting the increasing levels of power dissipation required.
The challenge for fan integration in this application module is not only for the ease of assembly but also the limitation of noise generated via various interfaces, such as heatsink, mounting assemblies, finger guards, wiring and connector interfaces, which influence the noise behaviour.
For this application, Sunon has not only tailored its MagLev system to the specific needs of the projects but also, through local engineering support, provided guidelines and design templates to optimise fan design integration within the module. Request a free brochure from Sunon ...
