Thermal heatsink is essential to electronic equipment

   Electronic equipment does not dissipate heat. As small as the computers we use for living and office, as large as large-scale equipment in industries such as industrial and medical treatment, we can't get around the problem of heat dissipation. So why is heat dissipation so important?

    Speaking of heat dissipation, we should first understand why it is hot. Take the computer CPU for example. CPU is composed of hundreds of millions of transistors, which are equivalent to circuit switches. The heat generated when the current passes through the micro components in the CPU is Joule heat. The heat released when the current passes through the PN junction, which accounts for the majority, is usually proportional to the frequency and the square of the current. Therefore, the faster the computer operation, the greater the workload of the processor, and the more heat will be generated.

   Some people may say that the heat is large, then it can be made of high-temperature resistant materials. In fact, due to the influence of various factors such as cost and technology, high temperature resistant materials can not be widely used. The effect of effective heat dissipation is much more than that of high temperature resistant materials.

      In addition to the computers, all other large electronic devices also need heat dissipation protection as long as they meet the requirements of intensive heating. Especially in medical treatment and precision instruments, once the temperature is too high, the equipment will deviate, and the consequences will be very serious.

    At present, the cooling means for electronic equipment is mainly air-cooled forced convection. In fact, from the development trend and power consumption scale of electronic chips, air-cooled cooling has become more and more difficult. The emerging water-cooled heat dissipation has opened a new channel, especially the successful application in the direction of computer heat dissipation, which has greatly driven the popularization of liquid cooling in the electronic industry. Quiet, efficient, stable and long life make up for the vacancy of heat dissipation in the industry. In the future, it will be more effectively committed to the cooling solution of the electronic industry.
