How to improve system performance with fan controls and protections
When an end system produces excess heat, designers commonly turn to dc fans to provide forced-air cooling for improved heat dissipation. Based on the well-known thermal-convection principle, forced air cooling should typically go beyond simply selecting a fan and running it full-time in your application. This full-time operation suffers from both its inefficiency and long-term […]
Understanding airflow fundamentals for proper DC fan selection
DC Fans have been the go-to solution in a designer’s thermal management toolbox for years, providing efficient cooling for products requiring the removal of heat from a few watts to several hundred watts. To ensure that the appropriate fan is selected, it is important to align the system’s cooling needs with the fan’s airflow characteristics. […]
An overview of fan bearing designs
by Ryan Smoot, CUI Devices Fans are a crucial feature of many electronic systems, maintaining operation within a certain temperature range, while ensuring electronics are working at their optimum level across their operational lifetime. Key to a fan’s design is the consistent running of the bearing on which the rotor spins. The sleeve bearing and […]
