Thermal design and simulation
With the development of electronic devices and devices towards miniaturization, power consumption continues to rise, and the demand for high heat flux density heat dissipation is becoming increasingly urgent. Thermal design is also receiving more attention. Thermal design is the use of appropriate and reliable methods to control the temperature of all electronic components inside a product, so that they do not exceed the maximum temperature required for stable operation under the working environment conditions, in order to ensure the safety of normal product operation and the reliability of long-term operation. In addition, controlling the heating amount in low-temperature environments to start the equipment is also an important aspect of thermal reliability. In modern society, with the increasing emphasis on energy consumption and environmental protection, thermal design has become an important technological field. It is increasingly valued in industries such as communication, security, PC, automotive, LED, and inverter, and has become an indispensable and important field in product research and development.
Thermal design refers to the process of determining the internal heat distribution and transfer path of a product or system through thermal analysis and simulation, and improving its thermal performance through optimized design. According to different application fields, thermal design can be divided into different types such as architectural thermal design, electronic thermal design, and automotive thermal design. In addition, according to different design goals, thermal design can also be divided into different aspects such as thermal management, heat transfer, and thermal comfort.
If thermal design is not carefully carried out and corresponding measures are not taken during the design phase, problems caused by heat may be discovered during the product trial production stage or even during mass production. Although the problem is not limited to heat, the closer to the mass production stage, the more time and cost it takes to take countermeasures, and even product delivery delays may occur, leading to the major problem of missed business opportunities. The worst-case scenario is that problems only arise in the market, leading to recalls and credit issues. So, thermal design is fundamentally crucial. Therefore, it is necessary to effectively carry out thermal design from the beginning stage. In addition, it is also important to recognize that with the changing trends in technological development, thermal design has become more stringent than ever before.
Thermal design work is a closed loop, from structural design in the early stage of the project, hardware layout, software control, material selection to temperature rise testing in the later stage, all should involve the participation of thermal design engineers. At the same time, the demand for faster product iteration has led to shorter design cycles for engineers. Therefore, more and more enterprises are adopting thermal simulation to reduce costs, accelerate research and development, improve the thermal performance reliability of power devices, and efficiently drive thermal design.
