Why does thermal managemnt is getting more and more important
With the continuous development of electronic technology, the integration degree of electronic chips is getting higher and the working frequency is also getting faster, which leads to an increasing amount of heat generated by electronic chips during the working process. In order to ensure the stable operation of electronic chips, research and application of heat dissipation technology have become crucial. This article will analyze and study from two levels: active and passive cooling, in order to explore more effective measures for the application of cooling technology.
Active cooling technology mainly includes air cooling, liquid cooling, and heat pipe technology. Air cooling technology is currently one of the most common heat dissipation methods, which uses a fan to blow cold air towards the heat sink and take away the heat through the sink. Liquid cooling technology involves flowing liquid over the surface of electronic chips and taking away heat through the circulation of the liquid. Heat pipe technology utilizes the phase change principle inside the heat pipe to transfer heat from the surface of the electronic chip to the heat sink.
Passive heat dissipation technology mainly includes heat sinks, heat sinks, and thermal conductive materials. Heat sink is one of the most common forms of passive cooling technology, which transfers the heat generated by electronic chips to the air through the heat sink. Heat sink is the process of connecting electronic chips with heat sinks, transferring heat to the sink through the fins, and then dissipating the heat into the air through the sink. Thermal conductive materials use materials with higher thermal conductivity to transfer the heat generated by electronic chips to other parts.
When choosing a heat dissipation method, it is necessary to consider the actual situation comprehensively. For example, for equipment with large space and low heat generation, air-cooled cooling can be chosen; For equipment with small space and high heat generation, liquid cooling or heat pipe cooling methods can be chosen. For some special application scenarios, such as high temperature, high humidity, etc., it is necessary to choose a more suitable heat dissipation method.
In short, with the continuous development of electronic technology, the research and application of heat dissipation technology have become crucial. Only by continuously optimizing and innovating cooling technologies can we better meet the cooling needs of electronic chips and ensure their stable operation.
