As shown in the figure, the DC cabin of the present application, as shown in the figure, the circulation unit, the air that the air inlet manifold enters are cold wind, and after passing through the cabinet, what comes out from the air outlet manifold is cold wind, and the realization is taken away the heat of data center and is realized cooling cycle. Specifically, air cooling and gas-liquid cooling are divided;
when only the cold air in nature is used for cooling, the first and second three-way valves enable the first cold air pipe, the second cold air pipe and the air inlet manifold to be communicated, and the air coming out of the air outlet manifold is subjected to heat exchange cooling with the external air through the first heat exchanger, so that the circulating cooling cabinet is realized.
When water cooling is needed, air cooled by the first heat exchanger flows out of the first cold air pipe and then is cooled by the water cooling box (air flow in the water cooling box is divided into the plurality of heat exchange pipes, water cooling is achieved, the water cooling effect is good, the temperature is further reduced), and circulating cooling is achieved when the air flows to the air inlet main pipe. In addition, the water quantity in the water cooling tank is adjustable, the first water outlet pipe or the second water outlet pipe can be used for discharging water by switching the second three-way valve, so that the water cooling tank is filled with water or only about half of the water, the length of the heat exchange pipe in the cooling water is controlled, and the control of the refrigeration degree is realized. And the water in the water cooling tank also realizes heat exchange with a natural cold water source through the water storage tank and the second heat exchanger, so that the water in the water cooling tank is also circulated, and the heat exchange is realized with the natural water. And when needing bigger refrigerating capacity for the water-cooling tank fills with water, and the refrigeration unit can realize the further cooling to the storage water tank, thereby realizes better refrigeration effect.
Since the cooling cycle of the present application relies on the cyclic heat exchange of multiple heat exchangers, and multiple circulation pipes are always submerged in water, and there are many elbows, special attention needs to be paid to the sealing performance of the heat exchange pipes, otherwise humidity imbalance in the data center may be caused. Therefore, when the first water outlet pipe is used for discharging water (the water level is higher than the first water outlet pipe by a section of height), the curved plate below is adopted for detection; when the second water outlet pipe is used for discharging water, the curved plates above and below are adopted for detection at the same time. When the water cooling tank is not used (the first three-way valve and the second three-way valve are not communicated with the water cooling tank), the water cooling tank is filled with water, the heat exchange pipe can be pressurized by the pressurizing air pump, the air tightness is detected, and the two curved plates can be used for jointly detecting at the moment. Before detection, because the water surface is higher than a curved plate used for detection (because the first partition plate and the second partition plate are both provided with one ends inclined upwards, bubbles cannot be retained in corners between the partition plates and the side walls of the water cooling tank in the process of water flow moving upwards), a small amount of bubbles possibly retained at the curved plate are shielded by the curved plate and cannot move upwards, at the moment, a water flowing pipe valve is opened, and a corresponding ultrasonic vibration unit is started, so that the bubbles retained at the position flow away through the water flowing pipe, after flowing away, the water flowing pipe valve and the ultrasonic vibration unit are closed, detection is carried out, and if bubbles are generated in the detection process (the generated bubbles can be retained at the curved plate), the bubbles are collected by an image collector, so that alarm is triggered, and timely maintenance is carried out. If no bubble appears, the hermetic seal is satisfactory. At the time of pressurization detection, the water cooling tank does not participate in cooling of the data center. When the water cooling tank participates in cooling of the data center (at the moment, the water surface submerges the first water outlet pipe or the second water outlet pipe and the corresponding curved plate), the method can be used for monitoring the heat exchange pipe in real time.
