Description
Technical Field
The invention relates to the technical field of server heat dissipation, in particular to a water-cooling and air-cooling dual-purpose redundant radiator of a traditional server and a using method thereof.
Background
With the rapid development of internet and internet of things scientific technologies, servers play more and more important roles in the internet industry, the server technology is continuously innovated and advanced, particularly, a CPU (central processing unit) is continuously updated and updated according to the Moore's law, and the power consumption of the servers is continuously increased along with the continuous improvement of the performance of the servers, so that the heat dissipation problem becomes a problem which server manufacturers have to face.
The traditional server heat dissipation is any one of air cooling heat dissipation, water cooling plate heat dissipation and complete immersion type liquid cooling.
In the above heat dissipation manner, in terms of air-cooling heat dissipation, firstly, as is well known, the air-cooling heat dissipation PUE is always high, the server for air-cooling heat dissipation has a built-in fan, the built-in fan needs to maintain a high rotation speed, and much electric energy needs to be consumed in the high rotation speed, secondly, the air-cooling heat dissipation data center needs to be provided with a whole set of air-cooling units to cool down the hot channel of the data center, and the annual power consumption of the air-cooling units is quite remarkable, and the cost is high; thirdly, as the power consumption of the CPU is higher and higher, the air-cooled heat dissipation can reach the bottleneck of the CPU immediately, and the heat dissipation requirement of the high-power-consumption CPU can not be met; finally, the noise of the built-in fan of the air-cooled heat dissipation server can reach 90 decibels, even exceeds 100 decibels, and the health of the data center is seriously affected for operation and maintenance personnel. The air-cooled heat dissipation server is relatively much lower in dependence on the refrigerating unit, and the built-in fan can keep the server normally running for several hours.
In the aspect of water cooling plate heat dissipation, the shortcoming of forced air cooling radiator can be solved to the water cooling plate radiator, but the water cooling plate radiator relies on central water circulating system very much, if water circulating system trouble or pipeline leak, the CPU heat will can't in time be taken away to the cold drawing, even if rotate for the built-in fan that other parts dispel the heat in the water cooling server at full speed, also can't take away the heat on the cold drawing radiator of bald, lead to whole data center server CPU to shut down because of high temperature in batches very short time.
The completely immersed liquid cooling heat dissipation technology is a non-traditional data center server design technology, is a new architecture, has the difficulties of stability of cooling liquid, system sealing, pressure control inside the system and the like, and has no technical solution which can not be popularized in batches and brought into the market.
