[0002] With the advent of the information explosion era, data centers have also developed rapidly. Therefore, more server cabinets must be stacked in the limited space of the data center to meet the usage requirements. However, at the same time, the increase in server cabinets generates a large amount of heat energy, which is very important for cooling the servers.

[0003] In the traditional technology, cooling equipment such as air conditioners and exhaust fans is relied on to cool the servers in the data center, resulting in high energy consumption. In the existing technology, the more commonly used energy-saving means is to use the external natural cold air to cool down, reduce the use of mechanical refrigeration, and reduce the start and stop of the compressors in the air conditioners. However, this method is not applicable in hot seasons. Moreover, the air conditioning system is used to cool the computer room, but the electricity cost is relatively high during the summer peak period. In addition, the phase change energy storage technology is used, but the phase change energy storage container is relatively far from the area to be cooled, so that when the phase change energy storage container releases cold, a large amount of cold is consumed in the transmission pipeline.

[0004] Therefore, the utility model provides an energy-saving cooling device for a data center to solve the above problems. Content of the Utility Model
