什么是 LDO 的热阻系数？
热阻系数 RθJA ，即 Junction-to-ambient thermal resistance，PN 结到环境的热阻，该参数反映了芯片发热的程度，值越大，相同负载功率下就发热越高，是跟封装类型尺寸相关的，封装越大，热阻系数就越小。

IC的热阻都由什么因素决定？为什么相同封装的IC热阻系数相差很多？
热阻参数，有结-壳热阻、结-散热器热阻、结-空气热阻，热阻值是经过JEDEC标准测试得到的。制造厂家不同、内部芯片尺寸不同，热阻参数也有可能不一样。
热阻和导热系数分别是什么意思？二者关系怎样？
热阻θ＝L/(λS)，式中：λ是导热系数，L是材料厚度或长度，S是传热面积。物体对热流传导的阻碍能力，与传导路径长度成正比，与通过的截面积成反比，与材料的导热系数成反比。

WHAT IS THE SHELF LIFE OF THERMAL GRIZZLY THERMAL PASTE AFTER OPENING?
If stored and packaged correctly, the thermal paste can be used for at least 3 years without any problems, and in many cases for considerably longer.
Can I use the Thermal Wizard Selection Tool without knowing my cooling requirements?
Yes. The Thermal Wizard provides four calculators for Device Cooling, Enclosure Cooling, Air Cooling and Liquid Cooling with preprogrammed examples. Each calculator has several examples to help you get started. Once you have determined the Qc value, you are able to specify the appropriate thermoelectric products.
What is the Thermal Wizard?
The Thermal Wizard is a product search and selection tool that helps engineers find the optimal thermal management solution for thermoelectric coolers, thermoelectric cooler assemblies and liquid cooling systems.
What are the benefits of using liquid instead of air cooling systems?
Liquid heat exchangers can reduce the thermal resistance of conventional heat sink fan dissipation mechanisms by a factor of 10 or more, which makes it much more efficient. This is due to the poor thermal properties of air versus coolants such as water. Liquid cooling systems have a more rapid cool down time, which means less time to reach the desired temperature. While conventional air cooling systems push air all around the system, and can potentially add heat from surrounding hot electronics, liquid cooling systems are equipped with a heat exchanger that routes heat away through a liquid circuit. Air-cooling systems in the higher capacity range often require larger fans, which can increase noise as well as the size of the system.
为何KennTherm在使用初期看不到与一般市售导热膏(Thermal Grease) 的差异？
由于一般市售导热膏(Thermal Grease)在长期使用时，会有dry-out的现象，会造成其热阻值上升，因此使用初期并不会看到KennTherm与一般市售导热膏(Thermal Grease)两者的差异。
When is a custom solution necessary to solve a thermal problem?
A standard solution is typically designed for general purpose applications. Since there are an unlimited number of application possibilities, standards cannot fulfill all application requirements. Achieving a fine-tuned specification generally results in some level of customization, whether it is capacity vs form factor or efficiency. Trial and test validation typically leads to determining if a standard is suitable for application or not.
KennTherm与一般市售导热膏比较如何？
使用初期KennTherm 的热阻值与一般市售导热膏(Thermal Grease)相近。但是随时间增加，由于一般市售导热膏(Thermal Grease)内的油脂挥发，热阻值会逐渐的变大，而KennTherm的热阻值不会因为时间的变化而改变。再者作业加工时一般市售导热膏(Thermal Grease)容易因加压而由周围流动溢出污染机构，而KennTherm无此一问题。
