The design requirements:
Thermal power- 140W
Al1060 Skived fin +Heat pipes
Heat sink size: 120*280*75mm
Fin thickness:0.8mm
Fin distance :2.4mm
heat sink base:7.0mm
Input flow Fan:125CFM
3000 PWM
(120x120x25mm Fan)*2pcs
Environment 28℃
The Max temperature of heat sink surface is below 50 ℃
The temperature difference of the same chip type is about 2 ℃
Making the thermal solution for the heat sink,we can see the heat source distribution in the heat sink, the minimum and maximum temperatures, and the fan flow rate.
The Max temperature of heat sink surface is 44.4℃,Data calculated based on thermal analysis software ANSYS ICPAK,Used the simple model method, the result will be different from the actual module.
