Data center cooling device based on condensate water recovery and wall body integration Technical Field The application relates to the technical field of data center infrastructures, in particular to a data center cooling device based on condensate water recovery and wall integration. Background Data centers are increasingly power consuming as a core physical carrier for digital economies. Data center energy consumption is statistically about 1% -2% of global power consumption and continues to grow rapidly. The energy consumption of the air conditioner refrigerating system is up to 30% -45%, and the air conditioner refrigerating system is the main energy consumption part next to IT equipment. The energy consumption of the refrigeration system is reduced, and the method has important significance for improving the energy efficiency ratio (PUE value) of the data center and realizing the target of double carbon. At present, the main stream technology path for reducing the refrigeration energy consumption of the data center is to utilize natural cold sources as much as possible, so as to reduce the operation time of mechanical refrigeration. The technology mainly comprises the steps of 1, naturally cooling the water side, namely, cooling the circulating water of the air conditioner by using outdoor low-temperature air or water body through a plate heat exchanger. However, in hot and humid areas, the natural cold source has short available time due to higher wet bulb temperature, and the system is complex to switch under partial load and has low efficiency. 2. And the air side is naturally cooled, and outdoor cold air is directly or indirectly introduced. The direct introduction faces the difficulty of air purification and humidity control, and the indirect introduction requires the addition of a large-sized air-air heat exchanger, which occupies a large area and has limited efficiency in damp and hot areas. 3. The evaporation cooling is to absorb heat and refrigerate by utilizing water evaporation, the effect is remarkable in a dry area, but the efficiency is rapidly reduced in a high humidity area, and the problems of frequent water quality treatment and maintenance and the like exist. 4. The natural cooling (heat pipe) at the fluorine side has high energy efficiency by utilizing the phase change circulation of the refrigerant, but has strict requirements on the indoor and outdoor height difference and pipeline installation and higher initial investment. In summary, when the conventional natural cooling technology is applied to a data center in a hot and humid area, the common problems of low natural cold source utilization rate, large equipment occupation area, complex system, low integration level with buildings and the like are generally existed. Meanwhile, a large amount of low-temperature condensed water (usually 10-15 ℃) is generated in the refrigerating and dehumidifying process of the data center air conditioning system, and the part of waste cold is usually directly discharged and cannot be effectively utilized.
