TECHNICAL FIELD

The present disclosure relates to the technical field of small water chiller for water circulation, and more particularly, to a small water chiller for water circulation in a data center.

BACKGROUND

As globally collaborative specific network equipment, a data center is used to transmit, accelerate, display, compute, and store data information on network infrastructure. Emergence of the data center guides people's understanding from a quantitative and structured world to an uncertain and nonstructured world. It will gradually become a part of modern social infrastructure, just like transportation and network communication, and has a positive impact on many industries.

At present, when in use, to ensure smooth and safe operation of the data center, generally corresponding cooling measures may be taken. For example, an existing water circulation refrigeration system is used, which is a refrigeration system mainly comprised of a cooling tower, a cooling water circulation pump, a water chilling unit, and a cold water circulation pump to refrigerate environment where the data center is positioned.

Referring to FIGS. 1 to 5 and FIG. 13, a small water chiller for water circulation in a data center includes a data center 1 and a machine room floor 2, where an auxiliary bracket touching the machine room floor 2 is mounted at a bottom of the data center 1. A closed heat transfer cylinder 3 is nested inside a corner of the data center 1, and a cooling trough positioned at a rear end of the data center 1 is provided on the machine room floor 2. Inside the cooling trough there is sleeved with a capsular cold water component 4, a limit support plate 5, a support shaft 6, an inclined pressure-regulating plate 7, an outlet one-way valve tube 8, and a reflux one-way valve tube 9. The capsular cold water component 4 is internally sleeved with a first reset spring, and a bottom of the capsular cold water component 4 is provided with a receiving cavity, which is provided with a small water chiller for refrigerating a cooling liquid inside the capsular cold water component 4. A middle of the support shaft 6 is attached into a side of the inclined pressure-regulating plate 7 by means of a bearing.

A surface on a top of the capsular cold water component 4 is glued and fixed to a surface on a bottom of the limit support plate 5, and two sides of the limit support plate 5 are fixed to an inner wall of the cooling trough by means of a screw; making it convenient for subsequent disassembly. A bottom surface of the capsular cold water component 4 is adhered and connected to an inner wall on a bottom of a demising trough. Both the top and the bottom of the capsular cold water component 4 are limited, which causes lateral deformation buffering of the capsular cold water component 4 after it is compressed.

An end of the outlet one-way valve tube 8 and an end of the reflux one-way valve tube 9 are connected to a liquid transport composite pipe fitting 10 and a reflux composite pipe fitting 11, respectively. An output end of the liquid transport composite pipe fitting 10 and an input end of the reflux composite pipe fitting 11 extend and attach to a bottom and a top of the closed heat transfer cylinder 3, respectively. Other end of the outlet one-way valve tube 8 and other end of the reflux one-way valve tube 9 extend and attach to two sides of the capsular cold water component 4, respectively.

The liquid transport composite pipe fitting 10 includes a main liquid transport tube 101, a first annular tube 102, and a first branch tube 103. An end of the main liquid transport tube 101 and an end of the first branch tube 103 are both attached to the first annular tube 102, other end of the main liquid transport tube 101 is connected to an end of the outlet one-way valve tube 8, and other end of the first branch tube 103 is used as the output end of the liquid transport composite pipe fitting 10 and is attached onto the bottom of the closed heat transfer cylinder 3. The reflux composite pipe fitting 11 includes a main reflux tube 111, a second annular tube 112, and a second branch tube 113. An end of the main reflux tube 111 and an end of the second branch tube 113 are both attached to the second annular tube 112, other end of the main reflux tube 111 is connected to an end of the reflux one-way valve tube 9, and other end of the second branch tube 113 is used as the input end of the reflux composite pipe fitting 11 and is attached onto the top of the closed heat transfer cylinder 3. The liquid transport composite pipe fitting 10 and the reflux composite pipe fitting 11 are structurally linked to the outlet one-way valve tube 8, the reflux one-way valve tube 9 and the capsular cold water component 4, to form a circulation channel for subsequent water circulation.

An outer side on a top of the reflux composite pipe fitting 11 is provided with a pressure-exerting rod piece 12 and a power output component 13, where an output structure of the power output component 13 is connected to an end of the pressure-exerting rod piece 12 in a transmission way, and other end of the pressure-exerting rod piece 12 extends to a surface in a middle of the inclined pressure-regulating plate 7 for adhesive connection.

The pressure-exerting rod piece 12 includes a curved support rod 121, a pressure-exerting sleeve roller 122, and a linkage rod 123. A side of the curved support rod 121 is attached to an inner side in a middle of the pressure-exerting sleeve roller 122 by means of a bearing, and other side of the curved support rod 121 is welded and fixed to an end of the linkage rod 123. A surface of the pressure-exerting sleeve roller 122 is adhered and connected to a surface in a middle of the inclined pressure-regulating plate 7. An outer side of the power output component 13 is covered with a semi-open protective shell. The power output component 13 includes a hydraulic rod 131 and a transition rod 132, where an output end of the hydraulic rod 131 is connected to an end of the transition rod 132 in a transmission way, and the transition rod 132 is used as an output structure of the power output component 13 and is connected to other end of the linkage rod 123 in a transmission way. A support seat is installed between a housing of the hydraulic rod 131 and a top of the machine room floor 2. The pressure-exerting rod piece 12 and the power output component 13 are combined to automatically exert pressure on the inclined pressure-regulating plate 7, and then the inclined pressure-regulating plate 7 synchronously exerts pressure on the capsular cold water component 4, allowing the cooling liquid inside the capsular cold water component 4 to flow in the circulation channel, to assist the closed heat transfer cylinder 3 in direct and targeted cooling of the data center 1 through water circulation.

Operating principles are as below. In the event of sudden failure of large cooling equipment, the hydraulic rod 131 inside the power output component 13 reciprocates, such that the output end of the hydraulic rod 131 drives, through the transition rod 132, the pressure-exerting rod piece 12 to carry out reciprocating rectilinear top pressure movement at the top of the inclined pressure-regulating plate 7, causing the inclined pressure-regulating plate 7 to exert reciprocating extrusion on the capsular cold water component 4.

When the capsular cold water component 4 is subjected to periodic extrusion, the cooling liquid inside the capsular cold water component 4 will incessantly enter the liquid transport composite pipe fitting 10 through the outlet one-way valve tube 8, and then enter the closed heat transfer cylinder 3. Next, internal heat generated by the data center 1 during operation is transferred by means of the closed heat transfer cylinder 3 and the cooling liquid. After internal space of the closed heat transfer cylinder 3 is filled up, the cooling liquid that absorbs a certain amount of heat will flow back to the capsular cold water component 4 through the reflux composite pipe fitting 11 and the reflux one-way valve tube 9. In this way; the direct and targeted cooling of the data center 1 is achieved through water circulation.

Each time when the capsular cold water component 4 is pressed and tiled, the small water chiller is not extruded, and the small water chiller is selected from technical products from Yingshang Toudengcang Technology Development Co., Ltd., and the cooling liquid inside the capsular cold water component 4 contacts the machine room floor 2 at maximum area. Next, the large-area machine room floor 2 and the small water chiller are used to achieve their own cooling, to meet continuous use effects based on water circulation cooling.

An inner side of the heat transfer pipe 18 is fixedly sleeved with a heat transfer sheet 19. Delivery of air inside the annular airbag 16 is achieved by means of extrusion deformation of the annular airbag 16 and the capsular cold water component 4, and synchronous air blast cooling of the cooling liquid inside the capsular cold water component 4 is achieved by means of the air transmission composite pipe fitting 17, the heat transfer pipe 18, and the heat transfer sheet 19, to further optimize the overall performance of the device.

Operating principles are as below. Regardless of whether it is in a manual operation or automatic operation, when the capsular cold water component 4 is extruded and deformed, it squeezes the annular airbag 16, such that the annular airbag 16 is synchronously deformed. Meanwhile, the air inside the annular airbag 16 is transported to the heat transfer pipe 18 through the air transmission composite pipe fitting 17 and achieve air blowing effects, to cool the heat transfer pipe 18. Next, auxiliary heat dissipation of the cooling liquid flowing inside the closed heat transfer cylinder 3 is performed by means of the heat transfer pipe 18 and the heat transfer sheet 19 through heat conduction.
