Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of computer room water chiller, and particularly relates to a computer room water chiller water spray device. BACKGROUND

[0002] In today's highly informationized society, as the core hub of data processing and storage, the stable operation of the internal equipment of the computer room is crucial to the accurate transmission and processing of information. The water chiller in the computer room, as the key heat dissipation equipment, undertakes the important task of cooling numerous high-power, high-heat electronic components and devices.

[0003] With the rapid development of information technology, the number of devices in the computer room is increasing, and the power density is also increasing, which makes the heat dissipation demand grow exponentially. The traditional computer room water chiller cooling technology gradually reveals many shortcomings in the face of this challenge.

[0004] The common cooling method of computer room water chiller in the past mainly includes air cooling and water cooling. The air cooling system promotes air flow by fan to take away heat, but the heat dissipation efficiency of this method is relatively low. When a large number of devices in the computer room are running and heat is concentrated, the air cooling system often cannot quickly and effectively remove heat, which easily leads to high temperature in the computer room, thereby affecting the performance and stability of the devices and shortening their service life.

[0005] Although the water cooling system is superior to air cooling in terms of heat dissipation capacity, it also has obvious defects. The spray head structure in the traditional water cooling system is simple, and the shape of the sprayed water flow is not fine enough to form uniform and fine water mist, which leads to insufficient contact with the surface of the water chiller and greatly reduces the cooling effect. Moreover, due to dust, fibers and other impurities in the computer room environment and mineral deposits in the water, the water spray holes of the spray head are easily clogged. Once clogging occurs, not only will the cooling water flow be reduced or even interrupted, causing local overheating, but also it may cause failure of the water chiller, posing a great threat to the normal operation of the computer room.

[0006] In addition, the existing cooling device cannot flexibly adjust the water spray angle and coverage during operation, making it difficult to adapt to the differences in heat dissipation requirements of different parts of the water chiller. This leads to the possibility of overcooling in some parts, while other critical parts do not get enough cooling, affecting the cooling efficiency and uniformity of the entire water chiller.

[0007] Therefore, we propose a computer room water chiller water spray device, which not only enables water mist to be sprayed all around the various parts of the water chiller body, avoiding local overheating and achieving comprehensive and uniform cooling, but also timely removes impurities from the water spray holes of the atomizing spray head, significantly reducing the risk of spray head clogging, ensuring long-term stable operation of the device, reducing maintenance costs and downtime.

[0027] The water chiller body 2 of the water chiller mainly comprises a compressor, a condenser, an evaporator and a throttling device (expansion valve or capillary tube, etc.), and the working principle is as follows:

[0028] 1. The compressor sucks in low-temperature and low-pressure refrigerant gas from the evaporator, and converts it into high-temperature and high-pressure gas through the compression of the compressor.

[0029] 2. The high-temperature and high-pressure refrigerant gas enters the condenser, and the condenser exchanges heat with the outside air or water to cool and condense the refrigerant gas into high-temperature and high-pressure liquid.

[0030] 3. The high-temperature and high-pressure refrigerant liquid is throttled and decompressed by the throttling device (such as an expansion valve) to become a low-temperature and low-pressure gas-liquid mixture.

[0031] 4. The low-pressure refrigerant gas-liquid mixture enters the evaporator, absorbs the heat of the cooled medium (usually water or air) in the evaporator, and the refrigerant completely evaporates into low-temperature and low-pressure gas, thereby achieving the cooling of the cooled medium.

[0032] The cooled medium is transported to the place or equipment that needs to be cooled after being cooled by the evaporator, and the refrigeration cycle is completed. The whole process is continuously cycled to continuously provide low-temperature refrigerant and achieve the refrigeration effect.

[0033] It should be noted that the water chiller body 2 belongs to the prior art and will not be described in detail here.

[0034] Meanwhile, the rotating assembly comprises a first motor 9 arranged on the support 3, the output end of the first motor 9 is connected with the connecting disc 4, and the connecting disc 4 is driven to rotate by the first motor 9.

[0037] The top of the water tank 10 is provided with a water inlet pipe, and the inside of the water inlet pipe is provided with a filter screen. The water enters the water tank 10 through the water inlet pipe, and the impurities in the water are filtered through the filter screen.

When the cooling work is completed, the arc-shaped protective plate 6 returns to the initial position under the action of the rotating assembly, and then the rotating assembly starts to work, drives the impurity removal disc 8 to rotate.
