Problems solved by technology

[0003] At present, traditional thermal management technologies, such as air forced convection cooling, single-phase liquid cooling, etc., often have problems with unsatisfactory heat dissipation due to factors such as insufficient heat transfer capacity or restricted by conditions.

At the same time, since the computer room system of the data center is basically in a state of uninterrupted operation, traditional cooling equipment needs to keep running to prevent the temperature of the computer room system from exceeding the standard, which not only increases the energy consumption of the data center, but is also prone to failure of the cooling equipment due to long-term operation The problem

In addition, although there are a variety of heat dissipation methods, in most cases the heat dissipation system only uses one or two of them, and the heat dissipation method is relatively simple, ignoring the changes in the basic heat load of the heat dissipation system caused by the outdoor ambient temperature changing with the seasons. As well as the dynamic load change of the cooling system caused by the outdoor ambient temperature changing with time during the day, it is easy to cause energy waste. Therefore, there is a need for multiple cold sources to work together and operate flexibly to achieve high-efficiency and low-energy cooling of the computer room system.
