[0017] This cooling source device is tightly integrated with the computer room and used in conjunction with the room's design. It provides both cool air and a cooling liquid source. In high-temperature seasons, using this device in addition to mechanical refrigeration can significantly reduce data center power consumption. In low-temperature seasons, it can even be used solely to cool the data center room. This device fully utilizes naturally cooled air and cold water, providing both cooling liquid and cool air, achieving a perfectly closed loop with the outside world.
[0018] The cooling liquid in this cooling source device mainly relies on the isenthalpic process between the external air and the sprinkled water in the packing, which cools the sprinkled water. The cooled sprinkled water is then pumped to the plate heat exchanger by the cooling water pump, where it exchanges heat with the higher-temperature cold liquid in the terminal air conditioner in the computer room. The heated cooling water is then pumped to the water distributor and sprayer by the cooling water pump. The water distributor sprays the heated cooling water into the packing, and the cycle continues. The cold liquid in the terminal air conditioner exchanges heat and then exchanges heat with the hot air in the server in the computer room to heat it up, and the hot air in the computer room exchanges heat and cools it down. The terminal air conditioner here is the row-to-row air conditioner, which cools the servers in its area.
[0019] The cooling air in this cooling source device is mainly generated by the evaporation of water mist into dry air. After passing through the filler, the external air is cooled to medium-temperature and high-humidity air. The air is then pumped to the adsorption zone of the adsorption wheel by the fan. The adsorption wheel adsorbs the medium-temperature and high-humidity air, turning it into medium-temperature and low-humidity air. The sprayer sprays the heated water in the plate heat exchanger into the medium-temperature and low-humidity air. The water mist evaporates rapidly, turning the medium-temperature and low-humidity air into low-temperature medium-humidity air. The air then enters the machine room, exchanges heat with the hot air in the machine room, and cools the room. A portion of the hot air in the hot channel enters the desorption zone of the adsorption wheel, desorbing the water vapor from the adsorption wheel and turning it into high-humidity and high-temperature air.
[0020] This device supplies cooling liquid to the cold aisle of the computer room, while cooling air is supplied to the active area. The adsorption wheel desorbs the hot air from the hot aisle. This device requires a computer room design and requires both inlet and outlet vents.
[0021] In order to replenish water to the cold source device in time, preferably, it also includes a water collecting and ventilation channel 23, a water collector 24, a water collecting tray 25, a water collecting storage tank 26, and a return water pump 27. The air inlet end of the water collecting and ventilation channel 23 is connected to the air outlet side of the desorption zone of the adsorption wheel 14, the air outlet end of the water collecting and ventilation channel 23 is connected to the water collector 24, the water collecting tray 25 is located below the water collector 24, the water collecting storage tank 26 is connected to the water collecting tray 25 through a pipeline, the water inlet end of the return water pump 27 is connected to the water collecting storage tank 26 through a pipeline, and the water outlet end of the return water pump 27 is connected to the water storage tank 19 through a pipeline.
[0022] As the amount of water used in the spray and evaporation decreases, external water replenishment is required. This device fully utilizes the high-humidity air during desorption and uses a water collector to collect water from the high-humidity air, thereby partially replenishing the water supply and reducing the pressure of external water replenishment. The water collected by the water collector is transported to the water storage tank through the return water pump.
[0023] In order to further reduce the external air inlet temperature and to ensure that the cold source device is not affected by the pollution of external air impurities, it is preferably also included a pre-cooling filler 28, a pre-cooling water distributor 29, a pre-cooling surface cooler 30, a pre-cooling water pump 36, a pre-cooling water receiving pan 31, and a pre-cooling water storage tank 32. The water inlet end of the pre-cooling water pump 36 is connected to the water storage tank 19 through a pipe, the water outlet end of the pre-cooling water pump 36 is connected to the water inlet end of the pre-cooling surface cooler 30 through a pipe, the water outlet end of the pre-cooling surface cooler 30 is connected to the pre-cooling water distributor 29 through a pipe, the pre-cooling filler 28 is located directly below the pre-cooling water distributor 29, the pre-cooling water receiving pan 31 is located directly below the pre-cooling filler 28, and the pre-cooling water storage tank 32 is connected to the pre-cooling water receiving pan 31 through a pipe.
[0024] The external air is precooled by setting a precooling surface cooler at the air inlet of the cold source providing device. The cold liquid in the precooling surface cooler comes from the cooling water in the water storage tank. At the same time, in order to prevent the external air from carrying impurities to contaminate the device, a precooling filler and a precooling water distributor are set on the air inlet side. The external air passes through the precooling filler, and the impurities are mixed with the water in the filler and flow into the precooling water receiving tray, and finally transported to the precooling water storage tank.
[0025] In order to ensure that the cooling water of the cold source device remains clean, preferably, the pre-cooling water tank 32 includes a filtering mechanism 33, a discharge valve 34, and a balancing water pipe 35. The filtering mechanism 33 is located below the water inlet of the pre-cooling water tank 32, and the discharge valve 34 is located at the bottom of the pre-cooling water tank 32. One end of the balancing water pipe 35 is connected to the pre-cooling water tank 32, and the other end is connected to the water tank 32.
[0026] The cloth shower water mixed with impurities flows into the pre-cooling water storage tank, is filtered by the filtering mechanism, flows into the clean water area, and flows into the water storage tank through the balancing water pipe. The balancing water pipe is set above the pre-cooling water storage tank, and the impurities are precipitated in the sewage area. A discharge valve is provided in the sewage area. By opening the discharge valve regularly, the precipitated impurities can be discharged.

[0028] By setting fillers to perform isenthalpic heat exchange with external air, cold air and cold water are obtained. The cold water is transported to the plate heat exchanger to exchange heat with the hot liquid at the air-conditioning terminal in the computer room. By setting an adsorption wheel, the high-humidity and medium-temperature air after the isenthalpic heat exchange is adsorbed with water vapor and turned into low-humidity and medium-temperature dry air. Then, by setting a sprayer, high-temperature water vapor is sprayed on the low-humidity and medium-temperature dry air. The water vapor absorbs heat and evaporates, and the low-humidity and medium-temperature dry air becomes cold air and enters the computer room to cool the hot air. The hot air enters the desorption zone of the adsorption wheel to desorb the water vapor in the desorption zone. The high-humidity air is collected by setting a water collection device and transported to the water storage tank for water replenishment. The outside air is pre-cooled by setting a pre-cooling surface cooler and pre-cooling fillers to further reduce the temperature of the outside air. The impurities in the outside air are purified and filtered by setting a pre-cooling water storage tank and a filtering mechanism.
[0029] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
