The thermal performance may affect reliability, efficiency and service life of engineered products. Excessive high temperature exposure may cause accelerated ageing, material deterioration or performance variations in components. Therefore, thermal validation should start as early as possible before a product undergoes physical testing. Thermal analysis software\u00a0allows engineers to model the heat behaviour, test for design conditions and detect potential thermal problems in their design process.<\/p>\n

Evaluating Temperature Distribution<\/strong><\/h2>\n

A key application for thermal analysis software is to gain an understanding of the temperature distribution throughout a component or system. Heat generation, heat conduction, heat convection and heat radiation can be modeled by engineers to find how the thermal energy flows through the design.<\/p>\n

This temperature distribution can help identify regions of hot or cold spots. If they are identified at the design phase, then the engineers can explore the possibilities of changing something before testing physical prototypes.<\/p>\n

Identifying Thermal Hotspots<\/strong><\/h3>\n

Even if the system temperature seems to be acceptable, localized hot spots can cause big reliability issues. The engineer can use simulation to look at the differences in temperature at certain parts of a design, at certain points between parts of a design, or at certain areas within a design.<\/p>\n

In one instance, the critical parts of an electronic assembly can be located in close proximity to components that generate heat. Thermal analysis software<\/strong><\/a>\u00a0can be used to determine if the proposed arrangement results in unacceptable temperature gradients, and if changes in component placement, or cooling are required.<\/p>\n

An investigation of different operating conditions<\/strong><\/h3>\n

Products are not usually tested at a single thermal condition. Thermal behaviour may be influenced by ambient temperature, workload, flow of power, airflow and surrounding components.<\/p>\n

Using thermal analysis software, engineers can evaluate designs for various boundary conditions and operating scenarios. Multiple simulations can be done to make sure the design stays within the defined temperature limits under normal, demanding and abnormal conditions.<\/p>\n

Comparing Cooling Strategies<\/strong><\/h3>\n

Another aspect of thermal design validation is the ability of the system to reject heat generated. Simulation can help engineers evaluate various cooling options prior to their physical realization.<\/p>\n

Possible design changes include heat sinks, heat interfaces, air flow paths, fans, vents, and\/or changes in material selection. The simulated results can then be compared and analyzed to gain knowledge on the changes that are required to give the designer a meaningful thermal improvement and the changes that can be made to the overall design.<\/p>\n

Supporting Design Iterations<\/strong><\/h3>\n

While physical prototypes are useful for validation, creating and testing a number of prototypes can become time consuming and expensive. In addition to the initial design phase, simulation is an additional stage of testing that occurs before physical testing.<\/p>\n

Engineers can change the geometry, materials, and locations of components and cooling systems and simulate again to test the impact of the changes. This cycle of design, build, test and redesign can pinpoint design drawbacks at an early stage and give more understanding of how a specific combination is performing.<\/p>\n

Improving Validation Before Physical Testing<\/strong><\/h3>\n

Physical validation is not a replacement for thermal simulation. Instead, it enables engineers to test the physical system with a more comprehensive design. From the simulation results, attention can be directed to areas that are critical and need more focus during the prototype testing phase.<\/p>\n

If the results from simulation and testing are compared, this may also provide a way for engineers to improve the properties of materials, boundary conditions or modelling assumptions. This forms a loop which can enhance the accuracy of later analyses.<\/p>\n

Supporting More Reliable Design Decisions<\/strong><\/h2>\n

Thermal design validation needs to be more than just meeting a set temperature. Engineers should be able to understand how heat is distributed, thermal gradient, hotspot and performance under various operating conditions.<\/p>\n

Thermal analysis software\u00a0can aid this process by offering a means of analyzing these factors prior to production. Combining engineering judgement and physical testing with thermal simulation can enable teams to uncover potential risks at an earlier stage and to assess design options and create products that offer increasingly predictable thermal performance.<\/p>\n\t\t\t\t\t\t\t
