We all know that Extruded Aluminium heatsink will perform better than flat and low cost Stamped Metal heatsink, given the same size. But how much better is the diecast or extruded heatsink over just a flat aluminium plate? Lets do some testing, we will perform three separate tests. Finned heatsink, aluminium plate of the same size as heatsink and aluminium plate with the fan forced cooling.
Test rig consist of 70 Watt thermal load applied by the centrally mounted resistor. The heat sink size is 100mm wide and 250mm long. Thickness of the fabricated aluminium plate is 4.0mm and extruded part...

HEATSINK OPTIMIZATION
Introduction
Optimal design of a heatsink, meeting program targets for cost, weight, size, and performance, is one of the more challenging activities within most electronics engineering teams. Without a dedicated solver, designers or thermal engineers can be involved in a game of ‘opinioneering’, which typically involves overdesign, or initiate an expensive and time-consuming physical design of experiments that provides limited results. In the case study below, we worked to optimize an extruded aluminum heat sink for an IGBT module in a low-cost, high-volume design. Reliability requirements (10-year life), harsh environments (vibration, elevated temperature), limited ability to perform maintenance (consumer...
