Thermal Analysis Tool Enables Low-Cost, Fast–to-Market Product Development

Funai Electric engineers and manufactures low cost, high quality electronics products. Their success surpassing the fierce competition in their industry is firmly linked to ambitious implementation of thermal analysis for product development and product issue troubleshooting. SC/Tetra HPC (High Performance Computing) solver is Funai Electric’s thermal analysis tool of choice and has been instrumental in helping the company achieve success.

Head Office of Funai Electric Co., Ltd. (Osaka, Japan)

 Funai Electric is a general consumer appliance manufacturer that designs, develops and manufactures electronic products such as video equipment, LCD TV and Blu-ray/DVD players, printers for home and office use, and other telecommunications devices and ancillary computer equipment. The company serves as an original equipment manufacturer (OEM) for other companies and also manufactures products under their own brands. These products are widely distributed throughout North America, South America, Europe, Asia, and other parts of the world.

​ Funai Electric has gained substantial credibility in the industry, as well as considerable market share, since being founded in 1961. Their remarkable ability to deliver low price, high quality products on schedule is the key to their success.

Thermal Analysis of a High-Heat-Source Projector

 Funai Electric first started applying thermal analysis software to develop a projector, whose light source generated large amounts of heat. Before using thermal analysis software, if a problem occurred during prototype production or during the temperature measurement tests, determining a solution required going back to the design and repeatedly making adjustments. Although Funai Electric knew they needed an alternative to this time-consuming and inefficient process, their engineers were used to working this way. They relied on estimations based on the previous data and experience, and this hindered them from making fundamental improvements. At the same time, Funai Electric customers demanded shorter development time and product miniaturization. This led Funai Electric to consider introducing CFD analysis.

SC/Tetra is a Perfect CFD Tool for Development

 One engineer at Funai Electric explains that the company decided to use SC/Tetra CFD software primarily because “the software was entirely developed by a reliable firm, who provided fast and extensive support.” Before making the final decision, Funai Electric requested each software vendor to present results from their software to compare performance and functionalities. The highly accurate results from the benchmark model analysis performed by Cradle convinced Funai Electric engineers that SC/Tetra was a very good choice. They were also well satisfied with the efficient communication with the Cradle staffs, noting that their questions were thoroughly answered in a short amount of time.

​  While Funai Electric’s main reason for using thermal analysis software was to design electronic devices, they decided to use SC/Tetra instead of HeatDesigner, a structured mesh thermal analysis software specially designed for electronics cooling. SC/Tetra enabled the Funai Electric engineers to create intricate, highly detailed models. Engineers could analyze their rotating disk drive products such as CD-RW and DVD drives for PC and video equipment. They were able to represent fans and blowers with a high degree of precision and perform the associated system analyses. After discussing software options with Cradle, Funai Electric decided that SC/Tetra provided the greatest amount of modeling flexibility.

Software that Meets the Demand for Parallel Computing

 When Funai Electric began using SC/Tetra, calculation time could be very long because of the high complexity needed to model the area around the projector lamp. This complexity imposed considerable computation load, and modeling the details of the rest of the projector further increased the computation time and burden. Upgrading computer hardware shortened the analysis time but only by a modest amount. In some cases, complicated models from the design team could still take over 200 hours to converge. This left no room in the schedule to consider alternative design concepts. The problem was much worse during the early phase of SC/Tetra introduction, when the geometry models contained too much detail. Requiring 200 hours to obtain a solution disappointed the engineers, who voiced the need for faster turnaround. To solve this issue, Funai Electric introduced SC/Tetra HPC solver with parallel computing. Parallel computing with 24 processors reduced computation time significantly.
