Auxiliary tool for assembling server CPU and radiator

Technical Field

The utility model relates to a server technical field, in particular to server CPU and radiator assembly auxiliary fixtures.

Background

With the development of the electronic technology in China, more and more electronic devices have been widely used.

Servers are important components in electronic devices, and are devices that provide computing services. Since the server needs to respond to and process the service request, the server generally has the capability of assuming and securing the service. The server is divided into a file server, a database server, an application server, a WEB server and the like according to different service types provided by the server. The main components of the server include a processor, a hard disk, a memory, a system bus, etc., and are similar to a general-purpose computer architecture, but the server is required to have high processing capability, stability, reliability, security, expandability, manageability, etc., because it needs to provide highly reliable services.
