Understand Your Products Thermal Performance with Ansys Icepak Software

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 so they can correct them quickly. Simulation also makes it practical to evaluate a wide range of alternative designs to optimize the design and ensure its safety under many different operating scenarios. Single physics solutions with relatively simple physical models are sufficient for some thermal management challenges, but 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 or generation of thermal mechanical stresses that may lead to early failure. Investigating thermal effects in the laboratory is often not practical beyond a few sets of conditions, since it is time-consuming and costly to replicate complex thermal scenarios.

Simulating the thermal performance of a product early in the design phase can save large amounts of time and money by getting the design of the early prototypes right 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 such as determining how heat is transferred through a fluid. However, many problems are more complex, such as those that involve multiple mechanisms of heat transfer, where heat is transferred through both solids and structures. Engineers often need to understand how heat is transferred by several different mechanisms through a complicated interconnected system in order to understand how their product or process will perform under a given set of conditions.
