Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling radiators, in particular to a rack-type liquid cooling radiator. Background Art

[0002] Servers are usually divided into rack servers, tower servers and computer room servers. Rack servers are computers that are installed in server cabinets, have uniform appearance specifications, and are easy to centrally manage, including 1U, 2U, 4U and other specifications. One of the most important performance indicators in a server is the CPU / GPU operating frequency. The higher the CPU / GPU operating frequency, the better the server performance, but at the same time, the server generates more heat, resulting in higher temperatures. When the temperature exceeds the operating temperature allowed by the CPU / GPU, the server will crash or even be damaged. Therefore, cooling technology is urgently needed to solve the problem of local high temperature of the CPU / GPU. However, air cooling is the main cooling method in data centers on the market, and air cooling data centers have not yet been popularized. The systematic cooling transformation of air-cooled data centers also has the problems of high cost, long cycle, and impact on the business of existing customers. Utility Model Content

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

This rack-mounted liquid-cooled radiator is integrated into a rack-mounted CDU for use by arranging a liquid inlet pipe, a circulation pipe, and a liquid outlet pipe, or a single unit or multiple units are connected in series or in parallel to the primary side of the CDU for heat exchange, and the heat exchanged is transferred to the coolant inside the circulation pipe in the bottom heat sink of the integral radiator. When the coolant flows, the fan inside the integral radiator will inhale cold air from the air-cooled data center.
