Description

Technical Field

[0001] The utility model relates to the technical field of machine room cabinet installation, in particular to a water-cooled machine room. Background Art

[0002] With the rapid development of mobile Internet, the construction of data centers in my country has developed rapidly. From the perspectives of safety, quality, environmental protection and other aspects, data centers are developing in the direction of intensive, large-scale and green.

[0003] The water-cooled computer room in the data center adopts water-cooled row-to-row air-conditioning technology. Water pipes are arranged in the computer room to achieve cooling effect through water circulation. Since chilled water needs to be introduced into the computer room, once the water pipe bursts and leaks, the water will spread to the entire computer room. Once the running equipment is flooded and shut down, it will cause immeasurable economic losses and social impact. Therefore, this type of computer room has very high requirements for waterproofing.

[0004] Traditional waterproofing construction mainly achieves waterproofing effect by fully covering the ground with polyurethane or polymer cement-based waterproof coatings. This approach has high requirements on the on-site environment. Before painting, the base layer must be clean and free of dust and debris. The coating needs to be mixed and matched on-site. The control of the mix ratio will directly affect the quality of later waterproofing. Over time, the surface layer and the waterproof layer will not be firmly bonded, and hollowing and cracking are prone to occur. In addition, the equipment area is not effectively isolated from the water pipe area. Once the water pipe bursts and leaks, it will spread to the equipment area, causing damage to the equipment. In the later stage, it will be affected by the installation of cabinets and equipment, making repair difficult and maintenance cost high.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in this field. Utility Model Content

[0010] Specifically, the water-cooled machine room includes a waterproof layer, which is applied above the base floor of the wet area and turned up to the outer side of the water retaining cofferdam to prevent water from the wet area from reaching the dry area and seeping down to the lower equipment.

[0011] Specifically, the water-cooled machine room comprises a cabinet base for fixing and supporting the cabinet and the water-cooled inter-row air conditioner, and the cabinet base spans across one side wall of the water retaining cofferdam.

[0012] Specifically, the water-cooled machine room includes a concrete foundation and a first chemical anchor, wherein the concrete foundation is located in the wet area; one side of the cabinet base is fixedly connected to the concrete foundation by the first chemical anchor to prevent the cabinet base from damaging the waterproof layer by drilling holes on the ground.

[0013] Specifically, the water-cooled machine room includes a second chemical anchor bolt, and the other side of the cabinet base is fixedly connected to the base floor located in the dry area through the second chemical anchor bolt.

DETAILED DESCRIPTION

[0031] Traditional waterproofing construction mainly achieves waterproofing effect by fully covering the ground with polyurethane or polymer cement-based waterproof coatings. There is no effective isolation between the equipment area and the water pipe area. Once a water pipe bursts and leaks, it will spread to the equipment area and cause damage to the equipment.

[0032] To prevent water leakage from burst pipes from spreading to areas where equipment is installed and causing damage to the equipment, see Figure 1 The utility model discloses a water-cooled machine room, which includes a machine room body, the machine room body includes a base floor 10, a plurality of water retaining cofferdams 2 are arranged above the base floor 10, the base floor 10 is divided by the water retaining cofferdams 2 to form a wet area for installing water pipes and a dry area for installing cabinets, the wet area is provided with a drainage device, the dry area is located inside the water retaining cofferdam 2 and is separated from the wet area by the water retaining cofferdam 2, and the dry area cannot be reached by water from the wet area.

[0033] The utility model utilizes the water retaining cofferdam 2 to physically isolate the wet area from the dry area. Once a water pipe leaks, the water retaining cofferdam will control the water potential in the wet area and will not flow to the dry area for installing the cabinet, thereby protecting the equipment.

[0034] See also Figure 1 , from a top view, the water retaining cofferdam 2 of this embodiment is a rectangle. It should be understood that the water retaining cofferdam 2 of this embodiment is not limited to a rectangle, but can be a polygon.

[0035] Specifically, see Figure 2 The water-cooled machine room includes a waterproof layer 9, and a waterproof layer 9 is arranged on the base floor 10 of the wet area. The waterproof layer 9 is used to prevent water from the wet area from reaching the dry area and seeping down to the lower equipment.

[0036] Specifically, see Figure 1 and Figure 2 The water-cooled machine room includes a cabinet base 4 for fixing and supporting the cabinet and the water-cooled inter-row air conditioner. The cabinet base 4 spans across a side wall of the water retaining cofferdam 2.

[0037] Specifically, see Figure 2 The water-cooled machine room comprises a concrete foundation 1 and a first chemical anchor bolt 31. The concrete foundation 1 is located in a wet area. One side of the cabinet base 4 is fixedly connected to the concrete foundation 1 by the first chemical anchor bolt.

[0038] In this embodiment, a concrete foundation 1 is set in the wet area, and one side of the cabinet base 4 is fixedly connected to the concrete foundation 1 by a first chemical anchor 31. This fixed connection method avoids drilling holes in the ground to damage the waterproof layer, thereby preventing the waterproof layer from being affected by the installation of the cabinet base to form small leakage points to the lower space, thereby protecting the equipment in the lower area.

[0039] Specifically, see Figure 2 The water-cooled machine room includes a second chemical anchor bolt 32, and the other side of the cabinet base 4 is fixedly connected to the base floor 10 located in the dry area through the second chemical anchor bolt.

[0040] Specifically, the drainage device includes a drainage floor drain, which is installed on the base floor 10 of the wet area. The waterproof layer protection layer 81 is sloped to the drainage floor drain. The drainage floor drain is not shown in the figure.

[0041] Specifically, see Figure 4 The water retaining cofferdam 2 is a reinforced concrete structure. The wall of the water retaining cofferdam 2 is wrapped with a steel structure. The steel structure includes four stress-bearing bars 7 and a plurality of annular stirrups 6. The stress-bearing bars 7 are perpendicular to the longitudinal section of the wall of the water retaining cofferdam 2 and are distributed at the four corners of the longitudinal section. The annular stirrups 6 are parallel to the longitudinal section of the wall of the water retaining cofferdam 2 and are distributed at intervals.

[0042] In a specific embodiment, see Figure 5 The concrete foundation 1 is also a reinforced concrete structure, which contains a steel bar structure having stress-bearing bars 7 and annular stirrups 6 .

[0043] If the waterproof layer is exposed, the on-site environment requirements are high, and the base floor must be kept clean before painting, without dust and debris. The paint needs to be mixed and matched on-site. The control of the mix ratio will directly affect the quality of later waterproofing. Over time, the surface layer and the waterproof layer will not be firmly bonded, and hollowing and cracking are likely to occur.

[0044] Therefore, further see Figure 2 The water-cooled machine room also includes a waterproof layer protection layer 81, and a waterproof layer protection layer 81 for anti-seepage and anti-cracking is provided on the waterproof layer 9. The waterproof layer protection layer 81 is made of fine stone concrete, with a two-way steel mesh inside, and cement sand is sprinkled on the surface and smoothed as it is hit, and the slope is laid to the drainage floor drain, and a compartment gap is set at the same time to prevent hollowing caused by concrete extrusion in the later stage.

[0045] In this embodiment, a waterproof layer protective layer 81 for preventing seepage and cracking is provided on the waterproof layer 9 to protect the waterproof layer and avoid hollowing and cracking of the waterproof layer.

[0046] For further information, see Figure 2 The water-cooled machine room also includes a base floor protection layer 82, which is poured on the base floor 10 of the dry area. More specifically, the base floor protection layer 82 is made of fine stone concrete, with a bidirectional steel mesh inside, and cement sand is sprinkled on the surface and smoothed as it is poured. At the same time, compartment gaps are set to prevent hollowing caused by concrete extrusion in the later stage.

[0047] Further, see Figure 2 The water-cooled room also includes a water leakage detection device 5, which is configured to give an alarm and feedback the leakage position when it detects a water leakage, thereby improving the overall safety and reliability of the room. Figure 2 The water leakage detection device 5 includes a water leakage rope arranged along the water pipe.

[0048] In a specific embodiment, the wall of the water retaining cofferdam 2 is 400 mm high and 150 mm wide. The wall of the concrete foundation 1 is 150 mm high and 200 mm wide.

[0049] Below, refer to Figures 1 to 5 , the construction method of the water-cooled machine room of this embodiment is described. The construction method includes the following steps:

[0050] Step 1: Measurement and setting out: Before construction, check the site dimensions according to the design drawings, and mark the elevation and control lines according to the design requirements. Mark the horizontal elevation line on the wall, and the longitudinal and transverse control lines of the concrete foundation 1 and the water retaining cofferdam 2 on the base ground 10. The overall deviation shall not exceed 3mm.

[0051] Step 2: Concrete formwork: After the laser level is used to determine the position according to the drawn control line, plywood is used for formwork to ensure the straightness of the formwork. Square wood is used to support and fix both sides to ensure the bearing capacity and stability of the formwork.

[0052] Step 3: Steel bar binding: Four Φ10 stress bars 7 are used for longitudinal support, annular stirrups 6 are prefabricated with Φ6 steel bars, the binding spacing of the concrete foundation 1 is 200mm, the water retaining cofferdam 2 is bound every 800mm, the steel bar model is HRB400, and the overall binding is firm and reliable.

[0053] Step 4: Concrete pouring and curing: Use C25 commercial concrete and deliver it to the building with a pump truck for pouring. Use a vibrator to vibrate evenly during the pouring process. After pouring, protect the finished product and carry out watering and curing for the specified time to ensure its bearing capacity and stability.

[0054] Step 5: Waterproofing of wet areas: After the concrete curing is completed, clean the base floor 10 of the wet area and apply a 2mm thick polymer cement-based waterproof coating to the floor to form a waterproof layer 9 of the wet area. Apply the coating 400mm on the outer side of the water retaining cofferdam 2, and apply the coating at least twice in the horizontal and vertical directions to ensure that the coating is even and no area is missed.

[0055] Step 6. Water-tightness test: After the waterproof coating has dried, promptly inject water into the wet area in the room. The water storage depth should not be less than 30mm and the water storage time should not be less than 24 hours. In the early stage of the water-tightness test, check downstairs every hour, and in the later stage, check downstairs every 2-3 hours. If leakage is found, stop the test immediately and re-perform the waterproof layer. After qualified treatment, test again until there is no leakage, which is considered qualified.

[0056] Step 7. Pouring of waterproof protective layer concrete: After the closed water test is passed, pour 50mm thick C25 fine stone concrete in the wet area, with φ4@150 bidirectional steel mesh inside, sprinkle 1:1 cement sand on the surface and smooth it as you go, and slope it at 2% to the drainage floor drain. Make 6m×6m partition joints inside the concrete to prevent hollowing caused by concrete extrusion in the later stage.

[0057] Step 8: Drill holes and install the cabinet base: After the overall waterproofing construction of the computer room is completed, the base is measured and positioned according to the cabinet design layout. Each cabinet base 4 spans the wall of one side of the water retaining cofferdam 2, and has two fixing points in the wet area concrete foundation and the dry area. Use a pistol drill to drill holes in the ground at the fixed point. The drilling depth must be strictly controlled according to the bolt length, especially in the wet area. The depth cannot exceed the height of the concrete foundation to avoid damaging the waterproof layer. After drilling, the holes need to be cleaned and chemical anchor bolts installed in time for the later fixing of the cabinet base.

[0058] According to the statistical analysis of the later operation and maintenance costs of the data center computer room that adopts the water retaining cofferdam waterproofing method of the utility model, compared with the traditional method of only setting a waterproof layer, from the perspective of the entire life cycle of the data center, the water retaining cofferdam waterproofing method will save about 150,000 yuan in operation and maintenance costs in the first ten years compared with traditional methods, and the long-term operation and maintenance costs will be saved more.

[0059] The water-retaining cofferdam waterproofing method will be more beneficial for later maintenance. The dry area and the wet area are separated, and the cabinet equipment is installed above the dry area. Water pipes are run in the wet area and a water leakage detection device is installed. Once a water pipe leak occurs, the water-retaining cofferdam can control the water level in the wet area, locate the leak point and issue an alarm in the background, which will not affect the area directly below the cabinet, thereby ensuring that the dry area always remains dry and avoiding damage to the equipment in the cabinet due to pipe bursting and leakage.

[0060] The utility model provides a water-cooled room idea and method. There are many methods and ways to implement the technical solution. The above is only the preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, several improvements and modifications can be made. These improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be implemented by existing technologies.
