Electronics Cooling | Active and Passive Cooling

Controlling temperature is critical to the efficiency, safety, and durability of many products and processes. With Ansys simulation you can improve thermal management of products and processes. By enabling engineers to understand the root cause of thermal problems, and identifying electronics active and passive cooling thresholds, thermal/electronic overheating issues can corrected in the pre-design stages.

In addition, simulation makes it practical to evaluate a wide range of alternative designs.  Including, design optimization to ensure product safety under many different operating scenarios.

Single physics solutions with relatively simple physical models are sufficient for some thermal management challenges.  However, many applications do not meet all the assumptions on which the simpler models are based.


Why Thermal Analysis Matters

Most products and processes have a thermal comfort zone, a range of temperatures in which they operate most efficiently. Operating outside this zone may cause problems such as failures of critical components.  Other potential issues include generation of thermal mechanical stresses which may also lead to early failure.

Investigating thermal effects in the laboratory is often not practical beyond a few sets of conditions. As it is, laboratory testing is time-consuming and costly to replicate complex thermal scenarios.

However, simulating the thermal performance of a product early in the design phase can save large amounts of time and money.  Through proper planning, engineers can achieve optimal design of early prototypes from a thermal management standpoint.

As a result, this would reduce the need for additional prototypes that might otherwise be required to diagnose and correct thermal issues. Simple computational fluid dynamics (CFD) software can be used to analyze thermal issues.  A common application includes determining how/how much heat is transferred through a fluid.

However, many problems are more complex.  For example, those that involve multiple mechanisms of heat transfer. Or, where heat is transferred through both solids and structures. Engineers often need to understand how heat is transferred by several different mechanisms. Often through a complicated interconnected system in order to understand how their product or process will perform under a given set of conditions.
