Thermal Design Of Electronic And Thermal Simulation Technology Applications

Because electronic products are developing according to power rise, equipment exquisite, environment diversification three trends of development, that causes the electronic products heat consumption increase in the limited spatial internal, the products internal heat flow density enlarge, temperature rise, thus raise the electronic component thermal failure probability and reduce the product thermal reliability, seriously influence product normal work. To ensure the thermal reliability of the components and electronic products, thermal design is very important. Due to the traditional hot design method belongs to one atonement method, it rely on the engineers experience and need a large number of calculations. But thermal design of the use of simulation technology may let engineers judge designs whether to satisfy the product the hot reliability before the prototypical manufacture, and shorten product development cycles, reduce development costs, improve product time pass rate. Therefore, the electronic industry is urgently needed thermal design method of simulation technology.At present, thermal simulation technology application tools software have several. But this topic use's tool software is FLOTHRM. FLOTHERM is a more popular and professional thermal simulation technology applications software at present, with a professional Fluid Dynamics (CFD) solver able to analyze a variety of fluid, and it includes FLOMERICS Software Company's unique experience in the heat transfer in electronic equipment and the databases for the electronics industry developed model library. It is the world's first CFD software for the field of electronic thermal. It is not only meet the professionals to solve complex electronics cooling problems, and suitable for the structure of general staff engaged in electronic product design to conduct fast and accurate thermal design.This paper describes the background and the practical value of the subject; Expounds the influence of temperature to electronic products, and the main cause of rising temperatures of electronic products; Introduced simply the heat transfer way and follows the law; Expounds thermal design considerations factor, the electronic component thermal characteristics, thermal design cycle, thermal design process, the choice of cooling technology and thermal design of the basic method. Introduce simply the FLOTHERM software's features and functions. Elaborate mainly the FLOTHERM software's application in thermal design of the electronic products.This topic expounds the processes and methods of thermal simulation by FLOTHERM simulation tool, based on Changhong ITV210 product development. Prototype test results have verified the accuracy of the simulation. It introduced that the thermal design method of simulation technology is feasible and reliable.
