Description

Technical Field

[0001] The utility model relates to the technical field of cooling, in particular to a cooling device for a deep pit data center. Background Art

[0002] During the use of data centers, a large amount of heat will be generated, so that the heat cannot be dissipated in time, which in turn affects the normal use of the data center. Therefore, cooling devices are needed to cool the data center to maintain the normal operation of the data center. In addition to configuring cooling devices, the site selection of the data center is also particularly important. Some data centers are located in the flat tunnel space on the side wall of the deep pit slope. Due to the low temperature and stability of the flat tunnel space, it can meet the needs of data center construction.

[0003] For example, a heat exchange device for a data center with application number CN220776322U includes a device main body, the condensing mechanism includes a condensing chamber, a second through hole is opened on both sides of the condensing chamber, a baffle is provided inside the condensing chamber, ice cubes are placed at the bottom of the baffle, a liquid nitrogen chamber is provided at the bottom of the condensing chamber wall, and a heat conducting plate is provided inside the liquid nitrogen chamber. The utility model provides a third through hole, ice cubes and heat conducting plates, so that after the ice cubes melt when they come into contact with the external gas with heat, they can be quickly cooled down and re-condensed through the heat conducting plates that are closely attached to the liquid nitrogen chamber. Because the temperature of liquid nitrogen is extremely low, the heat conducting plates that are closely attached to the liquid nitrogen chamber can maintain an extremely low temperature, thereby quickly solidifying the ice cubes. At the same time, due to the provision of the third through hole, there is an obvious temperature difference on both sides of the baffle, and the ice cubes will continuously output low temperature through the third through hole, thereby achieving the initial cooling of the gas with heat.

[0004] In the process of cooling the data center, on the basis of the cooling method proposed in the above-mentioned patent, a fan is added to blow air to increase the uniformity of cooling and maintain a good cooling effect. However, after the fan has been running for a long time, the fan blades are covered with dust, resulting in a decrease in wind force, which in turn affects the uniformity and cooling effect of the cooling.

[0005] Therefore, we propose a cooling device for deep pit data centers to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a cooling device for a deep pit data center to solve the problem raised in the above background technology that after the fan has been running for a long time, the fan blades are covered with dust, resulting in a decrease in wind force, which in turn affects the uniformity and cooling effect of the cooling.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a cooling device for a deep pit data center, comprising a mountain body, a natural water source stored on the mountain body, a cavern space provided inside the mountain body, a machine room provided in the cavern space, a plurality of cabinets placed on the floor of the machine room, a plurality of fans fixedly mounted on the ceiling of the machine room, a heat exchanger fixedly mounted in the gap between the machine room and the cavern space, a controller and a water treatment device fixedly mounted on the outside of the mountain body, a drainage pool provided on the outside of the mountain body, the water treatment device and the heat exchanger being connected via a liquid infusion pipeline, and the heat exchanger and the drainage pool being connected via a liquid drainage pipeline;

[0009] Preferably, the fan blade includes a blade, and a first slide groove is respectively opened on the top surface and the bottom surface of the blade, and the two first slide grooves are arranged in symmetrical positions. A second slide groove is opened on the bottom surface of the blade, and a plurality of third slide grooves are respectively opened on the inner walls on both sides of the second slide groove cavity.

[0010] Preferably, the dust cleaning component includes a scraper embedded and slidably installed in the inner cavity of the first chute, and the scraper is elastically connected to the inner wall of the inner cavity of the first chute via a plurality of first springs.

[0011] Preferably, when the fan rotates at a high speed, the centrifugal force generated by the scraper is greater than the elastic force of the first spring.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Under the action of centrifugal force, the scraper will slide in the direction away from the connecting part, and in the process of sliding, it will scrape off the dust on the surface of the blade to ensure that the fan is always in good working condition, so that the wind blown by the fan is even and powerful, thereby maintaining good cooling uniformity.

[0016] 2. During the flipping process of the fan blades, the T-shaped slide will be driven to slide through the connecting rod. The T-shaped slide will generate continuous vibration during the sliding process. The vibration is transmitted to the fan blades, causing the fan blades to be in a vibrating state.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 9 A cooling device for a deep pit data center includes a mountain 1. A natural water source 2 is stored on the mountain 1, which provides a circulating water source for the cooling device. A horizontal tunnel space 3 is opened inside the mountain 1. After monitoring the underground environment, the horizontal tunnel space 3 is built on the side wall of the deep pit slope of the mine to build a data center. The horizontal tunnel space 3 can meet the needs of data center construction due to its low-temperature and stable characteristics.

[0031] There is a machine room 4 in the adit space 3. Several cabinets 5 are placed on the floor of the machine room 4. The cabinets 5 are used for data processing and are also the source of heat. Several fans 6 are fixedly installed on the top surface of the machine room 4. The setting of the fans 6 is to increase the uniformity of cooling and thus achieve a good cooling effect. A heat exchanger 7 is fixedly installed in the gap between the machine room 4 and the adit space 3. The heat exchanger 7 is mainly used to achieve a heat exchange effect and thus take away the heat generated inside the machine room 4. A controller 9 and a water treatment device 8 are fixedly installed on the outside of the mountain 1. The controller 9 is used to coordinate and control each The components operate stably. A drainage pool 10 is also provided on the outside of the mountain 1. The water treatment equipment 8 and the heat exchanger 7 are connected by a liquid infusion pipe 20. The heat exchanger 7 and the drainage pool 10 are connected by a liquid infusion pipe 30. After the natural water source 2 is treated by the water treatment equipment 8, it enters the interior of the heat exchanger 7 through the liquid infusion pipe 20 and flows inside the heat exchanger 7. During the flow, the heat generated inside the machine room 4 will be taken away, and finally the water with heat will be transported to the drainage pool 10 through the liquid infusion pipe 30 for storage and cooling so that it can be used later.

[0032] The fan 6 includes a mounting frame 61 fixedly mounted on the top surface of the machine room 4 and a turntable 62 rotatably mounted at the lower end of the mounting frame 61. The mounting frame 61 plays the role of installing and fixing the entire fan 6. A plurality of connecting members 63 are fixedly mounted on the edge of the top surface of the turntable 62. The plurality of connecting members 63 are arranged in a circular array on the top surface of the turntable 62. A fan blade 64 is provided on one side of the connecting member 63. The fan blade 64 and the connecting member 63 are rotatably mounted through a hinge 65. A dust cleaning component 66 is slidably mounted on the fan blade 64. When the turntable 62 rotates at high speed, it will drive the fan blade 64 together through the connecting member 63. It rotates at high speed. Since the fan blades 64 and the connecting member 63 are rotatably installed through the hinge 65, during the rotation of the fan 6, under the action of centrifugal force, the fan blades 64 will flip upward until the fan blades 64 and the connecting member 63 are in a parallel state. At this time, the air can be blown normally and will not affect the uniformity of cooling. At the same time, the dust cleaning component 66 will slide in the direction away from the connecting member 63 under the action of centrifugal force, and will scrape off the dust on the surface of the fan blades 64 during the sliding process, ensuring that the fan 6 is always in good working condition, thereby maintaining good cooling uniformity.

[0033] A vibration assembly 67 is provided on the bottom surface of the fan blade 64, and the vibration assembly 67 is movably connected to the connecting piece 63. When the fan 6 stops running, the centrifugal force gradually disappears, and the fan blade 64 begins to flip downward under the action of gravity. During the downward flipping process, the vibration assembly 67 will be driven to operate, so that the fan blade 64 is in a vibrating state. At the same time, the dust cleaning assembly 66 begins to slide in the direction close to the connecting piece 63, and will also scrape off the dust on the surface of the fan blade 64. Since the fan blade 64 is in a vibrating state, it can achieve a better cleaning effect on the fan blade 64, so that the fan 6 is in a better working state, further enhancing the uniformity of cooling. When the stopped fan 6 starts running again, the fan blade 64 flips upward again under the action of centrifugal force, and can still drive the vibration assembly 67 to operate during the flipping process, so that the fan blade 64 is in a vibrating state, and then cooperate with the dust cleaning assembly 66 to achieve a good cleaning effect.

[0034] The fan blade 64 includes a blade 641, and a first slide groove 642 is respectively opened on the top surface and the bottom surface of the blade 641. The two first slide grooves 642 are arranged in symmetrical positions. A second slide groove 643 is opened on the bottom surface of the blade 641, and a plurality of third slide grooves 644 are respectively opened on the inner walls on both sides of the inner cavity of the second slide groove 643.

[0035] The dust cleaning assembly 66 includes a scraper 661 embedded and slidably installed in the inner cavity of the first slide groove 642 , and the scraper 661 is elastically connected to the inner wall of the inner cavity of the first slide groove 642 through a plurality of first springs 662 .

[0036] When the fan 6 rotates at a high speed, the centrifugal force generated by the scraper 661 is greater than the elastic force of the first spring 662 .

[0037] In this embodiment: when the turntable 62 rotates at high speed, the scraper 661 will generate centrifugal force. When the centrifugal force is greater than the elastic force of the first spring 662, the scraper 661 will slide in the direction away from the connecting member 63 under the action of the centrifugal force. During the sliding process, the dust on the surface of the blade 641 will be scraped off, which is used to ensure that the fan 6 is always in good working condition, so that the wind blown out by the fan 6 is uniform and powerful, thereby maintaining good cooling uniformity.

[0038] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 4 - Figure 9The vibration component 67 includes a mounting base 671 fixedly mounted on the bottom surface of the connecting member 63, a T-shaped slide 672 is slidably mounted in the inner cavity of the second slide groove 643, and the T-shaped slide 672 and the mounting base 671 are movably connected through a connecting rod 673. A vibration column 674 is slidably mounted in the inner cavity of the third slide groove 644, and the side wall of the vibration column 674 is elastically connected to the inner wall of the inner cavity of the third slide groove 644 through a second spring 675.

[0039] Arc surfaces are provided on the sidewalls at both ends of the vertical section of the T-shaped sliding piece 672 , and the T-shaped sliding piece 672 is provided in the gap between the two vibration columns 674 .

[0040] In this embodiment: when the fan 6 stops running, the centrifugal force gradually disappears, and the fan blades 64 begin to flip downward under the action of gravity. During the downward flipping process, under the support of the connecting rod 673, the T-shaped slide 672 begins to slide in the inner cavity of the second slide groove 643. When the T-shaped slide 672 passes over the two vibration columns 674, the two vibration columns 674 are respectively ejected toward the middle of the inner cavity of the second slide groove 643 under the elastic force of the second spring 675 until the two vibration columns 674 collide and vibrate. Since there are multiple pairs of vibration columns 674, the T-shaped slide 672 will generate continuous vibration during the sliding process, and the vibration is transmitted to the fan blades 64, so that the fan blades 64 are also in a vibrating state. At the same time, the scraper 661 begins to slide in the direction close to the connecting member 63 to scrape off the dust on the surface of the fan blades 64. Since the fan blades 64 are in a vibrating state, the fan blades 64 can be better cleaned, so that the fan 6 is in a better working state and the uniformity of cooling is further enhanced.

[0041] When the stopped fan 6 starts to run again, the fan blades 64 flip upward again under the action of centrifugal force. During the flipping process, the T-shaped slide 672 can be driven by the connecting rod 673 to start sliding in the opposite direction in the inner cavity of the second slide groove 643, which will also generate continuous vibration and transmit the vibration to the fan blades 64, thereby making the fan blades 64 in a vibrating state, and then cooperate with the cleaning component 66 to achieve a good cleaning effect.

[0042] In addition to the above-mentioned water cooling method, freezing cooling is also an option. The freezing liquid cooling system includes a cooling liquid pool, a circulating cooling liquid pipe, and a supporting machine room 4. By setting up several cooling stations near the mine, burying cooling liquid pipes around the mine slope rock tunnel, and pumping the cooling liquid to circulate in the cooling liquid pipes of the data center tunnel, the data center server storage space can be quickly cooled, providing the data center with efficient and stable cooling functions under extreme conditions, such as Figure 10-11 The specific implementation steps are as follows:

[0043] Step 1: Freezing station construction: Mark an appropriate location near the selected construction site to establish a freezing station. The freezing station should be equipped with appropriate equipment to facilitate the rapid introduction of liquid nitrogen and continuous monitoring of its status during operation.

[0044] Step 2: Cooling pipeline layout: After the construction of the freezing station is completed, the next step is to lay the cooling pipeline. The purpose of laying the cooling pipeline is to achieve effective transportation and circulation of liquid nitrogen to achieve rapid cooling of the designated area. The size and number of required pipes are determined based on actual conditions such as production scale, production capacity, and system layout.

[0045] Step 3: Liquid nitrogen freezing operation; After the cooling station and cooling pipeline are ready, the liquid nitrogen freezing operation can be started. Liquid nitrogen is injected into the cooling pipeline through the freezing station and allowed to circulate in the pipeline to achieve the purpose of freezing the surrounding strata.

[0046] Step 4: Maintenance and inspection: During the construction process, the frozen soil shell should be inspected and maintained regularly.
