TA1 = Ambient room temperature under normal operating conditions ie: 20☌, sea level, clean filters, typical power usage. TE = Exhaust temperature of equipment at full fan speed under normal operating conditions, ie: 20☌, sea level, clean filters, typical power usage. Once these variables are established, the equipment’s temperature rise, Delta T can be determined.Įquipment Temperature Rise, Delta T = TE – TA1 Using thermal analysis computer modeling early in the product design is vital in determining your cooling system variables. Heat Sources (power dissipation of devices) higher semiconductor junction temperatures at reduced fan speeds. The key to designing an effective adaptive fan speed control system for electronics applications is striking the right balance between reduced noise, energy savings, fan life, constant semiconductor junction temperatures vs.
