JVC VN-V685U White paper: Thermal Simulation is Key to JVC CCTV Product Relia - Page 4

In addition to product performance tests, JVC regularly performs advanced thermal simulations, such as ones shown in Figure 3, to improve product design. The use of thermal simulation earlier in development makes it easier to visualize heat in every part of every component, thus enabling engineers to prevent thermal issues and create products with significantly greater reliability. Visualization of heat Visualization of airflow Figure 3. Thermal simulation illustrates potential design issues. Preventing thermal issues through thermal analysis and design requires careful electronic and mechanical engineering. As show in Figure 4, the process is repeated through a number of iterations to resolve any thermal issues at an early stage of development. Step 1 Power consumption of main heat-generating parts calculated Potentially at-risk parts isolated Heat dissipation calculated Target temperatures determined Step 2 Mounting positions studied Measures considered for potentially at-risk parts Step 3 3D modeling Shapes and conditions input Power consumption Thermal conductivity and other factors Step 4 Analysis Airflow estimated Convergence determined NG Step 5 Results Figure 4.
