  People are inseparable from network technology in daily work and life, It even can be said that the society is inseparable from the network. As a node of the network, the computer server that stores and process 80 % of the data of the network which requires 24 hours Working uninterrupted.

  Computer server is a high -performance computer, network terminal devices such as family and microcomputers access the Internet, obtain information, communicate with external communication, entertainment, etc., and must also pass the computer server. Therefore, it can also be said that the computer server is "organizing" and " Leading "these devices. A long -term and efficient computer server is what a company has to own.

  There are many factors that affect the computer server working, and the thermal issue is one of the main factors. The computer server is a high -performance computer, and it is also a machine with high power consumption. Most of the company would put the server in a exclusive air -conditioned computer room, the machinery and equipment generate heat is unavoidable, mainly because the power of electric energy cannot be fully converted. Most of the energy will be lost in the form of heat, so it will cause the machine and equipment to heat up. The air is a bad conductor of heat, the continuous heat generated by the server CPU will make the equipment overheat.

  So how to solve the thermal problem of server is important to mantain the performance of server. For server cooling, there are two main cooling types: Air cooling and liquid cooling, due to the liquid cooling cold plate is very expensive and difficult to install, air cooling heat sink is more widely used in server market. As different server as different power, the air cooling heat sink can be classified into several types such as aluminum extruded heatsink, heat pipe heatsink, skived fin heatsink, and vapor chamber heatsink. For high performance server, aluminum zipper fin copper vapor chamber heatsink is the best air cooling solution, as the vapor chamber can conduct and spread the heat rapidly.

  Vapor Chamber is a component that transmits heat very efficiently, vapor Chamber is also called the vacuum cavity thermal plate heat dissipation technology. With the increase in power consumption and heat of the game graphics card, a cooling solution provided by a cooling manufacturer called Celsia for AMD high-end graphics cards. Today, Vapor chamber heatsink is widely used in server, telecommunication, GPU and other industrial area.

  Vapor Chamber technology is similar to the heat pipe in principle, but there are some difference in the conduction method. The heat pipe is a one -dimensional linear heat conduction, while the heat in the vapor chamber is conducted on a two -dimensional surface, so the efficiency is higher.

Specifically, after absorbing the heat of the chip at the bottom of the vacuum cavity, the evaporation spread to the vacuum cavity, transmit the heat to the zipper fins, and then condense to the liquid back to the bottom. This kind of refrigerator -like evaporation and condensation process is rapidly circulating in the vacuum cavity, achieving a high heat dissipation efficiency.

  Aluminum zipper fin copper vapor chamber heatsink is designed for high power applications due to its excellent thermal conductivity and heat dissipation ability. the components and process as below:

Aluminum zipper fin: it's produced by high speed stamping machine, then nickel plated for soldering, aluminum zipper fin is popular due to it's excellent thermal dissipation ability, lightweight, low cost.

Vapor chamber: the top cover and bottom base are manufactured by stamping machine, the material is usually copper as it's a better conductor than other metals. After mesh welding and difusion bonding, vaccum, filling water, etc. A vapor chamber is completed, it's a critical thermal component for high power devices.
