  The thermal solution of servers has always been the focus of the industry. In nowadays, when the computing density is getting higher and higher and the power consumption is increasing, the thermal problem of servers, especially the data centers with a large number of application servers, the thermal issue is always the first consideration, and because of the external heat dissipation is difficult to completely solve the problem, and the heat dissipation efficiency is low, the internal part of the server is overheated, which cannot meet the requirements of the safe server working temperature. Therefore, more and more server manufacturers have focused the thermal issues of the server internal part especially the CPU.

   For server cooling, especially server CPU cooling, simply increasing the number of fans or increasing the fan speed cannot solve the problem very well. The more fans, the faster the speed, the more power consumption and the greater the noise. For users, power consumption and noise are also big problems. so we need to design a high heat dissipation efficiency heat sink to remove the heat from the CPU and dissipate it to air faster. 

  The server CPU is the CPU (Center Process Unit central processor) used on the server. The server is an important device in the network, it is necessary to accept access from dozens of people and as many as tens of thousands of people. Therefore, strict requirements such as rapid throughput, super stability, and long -term operation. As the server have large data, therefore, the CPU is the "brain" of the computer and the primary indicator of the server performance. The CPU of the server is distinguished according to the CPU's instruction system, which is usually divided into two types: CISC type CPU and RISC type CPU. 

   As the CPU is the core ofcomputing and control core of the computer system also it is the final execution unit for information processing and program operation. Since the appearing of the CPU, it has made huge development in logical structure, operating efficiency, and functional extension. 

  The CPU appeared in the era of large -scale integrated circuits. The iterative update of the processor architecture design and the continuous improvement of the integrated circuit process prompted it to continuously develop and improve.

 From the initial dedicated to mathematical calculations to the widely used in general computing, from 4 to 8, 16, 32, 32 -bit processors, and finally to 64 -bit processors, from each manufacturer's incompatibility to the emergence of different instruction set architectures, The CPU has been developing rapidly since its birth.

  As the CPU circuit is more integrated and complicated, the thermal dissipation is the most important issue to think about, if the server CPU is overheated, the whole system could not work normally even shut down. So an appropriate heat sink for server CPU is essential and it's the most improtant point when designing the server system.

  Currently the most popular server CPU heat sink is heat pipe heat sink, the heat pipe heat sink is an efficient radiator device, which has unique heat dissipation characteristics. It has a high heat transferring rate, and the temperature between the evaporation end and the condensation side  is even.

  The thermal resistance of the radiator is determined by the thermal conductivity of the material and the effective area in the volume. When a physical aluminum or copper radiator reaches 0.006m³, it can not significantly reduce the heat resistance by increasing its volume and area. For separate semiconductor devices with double -sided heat dissipation, the heat resistance of all -copper or all -aluminum heat sink can only reach 0.04 ° C/W. The heat pipe radiator can reach 0.01 ℃/w. Under natural convection cooling conditions, the performance of heat pipe radiator can be increased by more than ten times compared to the physical radiator.

  The Intel CPU server heat pipe heat sink has the following advantages:

① The heat transferring speed is fast, and its ability to transfer heat is more than 1,000 times faster than the same size and weight copper pipe;

② Small volume and light weight;

③ The heat dissipation efficiency is high, which can simplify the heat dissipation design of electronic equipment, such as turning wind cold to self -cold;

④ No need to add power supply, no special maintenance is required at work;

⑤ After the temperature is very good, after the thermal balance, the temperature gradient of the evaporation end and the condensation end is quite small;

⑥ It is stable and reliable and does not pollute the environment.
