Description

Technical Field

[0001] This invention belongs to the field of DC cabin technology, and particularly relates to a DC cabin with fire extinguishing function. Background Technology

[0002] A Data Center Cabin (DC) is a modular data center infrastructure that integrates IT cabinets, cooling, power distribution, fire protection, and monitoring systems. Through factory prefabrication and rapid on-site assembly, it enables rapid deployment and flexible expansion of data centers, and is widely used in cloud computing, AI computing centers, and other scenarios. With its standardized, modular, and intelligent features, the DC has become a key component in modern data center construction.

[0003] Due to the different types of IT equipment, existing data cabinets in DC compartments cannot achieve full modular installation, docking, or disassembly. Moreover, the heat dissipation and cooling of data equipment in the cabinets mostly rely on the air conditioning equipment in the DC compartment to cool the entire space, which results in low heat dissipation efficiency and high energy consumption.

[0004] If the IT equipment in the data cabinet of the DC compartment can be placed in a small, sealed space that can only accommodate its volume, and the IT equipment in the small sealed space can be cooled by targeted heat dissipation, then the space for cooling the air conditioning equipment can be reduced to the small sealed space around the IT equipment, thereby effectively improving the heat dissipation efficiency of the air conditioning equipment for the IT equipment and achieving the goal of effectively reducing the energy consumption required for heat dissipation.

[0005] Meanwhile, the use of inert gas to pre-ignite each IT device located in a small, sealed space can improve the fire suppression of the DC compartment. If the automatic switching between heat dissipation and fire suppression in the small space where each IT device is located can be achieved, it will be more conducive to the targeted fire suppression of IT devices and improve the fire suppression efficiency.

[0006] This invention designs a DC compartment with fire extinguishing function to solve the above problems. Summary of the Invention

[0007] Based on this, it is necessary to address the problems existing in current data center (DC) compartments by providing a DC compartment with fire suppression capabilities. This involves installing IT equipment inside the data cabinet using a housing assembly, creating a small, sealed space around each IT device that can be modularly connected to the heat dissipation and fire suppression structures on the cabinet. Furthermore, the housing assembly can automatically switch between heat dissipation and fire suppression, achieving targeted fire suppression and heat dissipation for IT equipment while improving the efficiency of heat dissipation and fire suppression and reducing the energy consumption of heat dissipation and fire suppression.

[0020] The beneficial effects of this invention are: 1. The data cabinets inside the cabin of the present invention are arranged in a U-shaped channel with the surrounding walls of the cabin to achieve the heat insulation effect between the cabin and the high temperature outside. The air intake and exhaust components at the top of the cabin can exhaust the inert gas discharged into the cabin after the equipment inside the data cabinet has been extinguished, thereby completing the ventilation of the DC cabin and facilitating the normal entry and exit and work of the staff.

[0021] 2. In this invention, the data cabinets arranged within the cabin are not enclosed with cabinet doors, thereby reducing cabinet costs. The IT equipment is vertically installed within the cabinet using modular enclosure assemblies that provide a small, sealed space. These enclosure assemblies can be modularly and synchronously pushed and plugged into the first air supply pipe and return pipe of the air-cooled heat exchanger on the data cabinet, as well as the second air supply pipe and pressure relief pipe for transporting and depressurizing inert gas. This effectively improves the installation efficiency of the IT equipment and the efficiency of the connection between the enclosure assemblies and the fire extinguishing and heat dissipation structures.

[0022] 3. The switching component in the casing assembly of the present invention can cut off the supply of cold air and the return gas recovery from the air-cooled heat exchanger to the interior when the IT equipment inside catches fire, and connect the gas storage tank to supply inert gas to the interior, so that the inert gas can be quickly filled into the casing assembly and achieve efficient fire extinguishing.

[0023] 5. In this invention, the cable winding assembly inside the housing of the casing assembly can keep the data cable and power cable taut and retracted during the process of the IT equipment entering and exiting the housing without interfering with the movement of the IT equipment.

The telescopic rod 345 consists of a rod sleeve 346 fixed to the slide seat 332 and an inner rod 348 sliding within the rod sleeve 346. A third spring 347 is disposed within the rod sleeve 346 to pull the inner rod 348 inward. A wheel seat 349 is disposed at the end of the inner rod 348. A tension wheel 350 is disposed within the wheel seat 349. The data cable 351 or power cable 354, whose two ends are respectively fixed to the rear side of the housing 301 and the rear side of the IT device 327, is connected to the second guide wheel 353 and the second spring 347. Guided by a guide wheel 352, the device is mounted on a tension wheel 350 in a position perpendicular to the housing 301 and the rear side of the IT equipment 327.

[0039] In a further embodiment, such as Figure 23 , Figure 25 As shown, the synchronization component 357 includes two fourteenth gears 358 respectively disposed at the lower end of the fourth pin 356 where the two second baffles 355 are located.

[0040] In this invention, the data cabinets 200 inside the cabin 101 are arranged in a U-shaped channel configuration with the surrounding walls of the cabin 101 to achieve heat insulation from the high-temperature external environment. The air intake assembly 104 and exhaust assembly 105 at the top of the cabin 101 can exhaust the inert gas released into the cabin 101 after the equipment inside the data cabinets extinguishes a fire, thereby completing the ventilation of the DC cabin and facilitating normal entry and exit for personnel. In this invention, the data cabinets 200 arranged inside the cabin 101 are not enclosed with cabinet doors, thus reducing the cost of the cabinets 201. The IT equipment 327 is vertically installed within the cabinet 201 using modular housing assemblies 300 that provide a small, sealed space. The housing assembly 300 allows for modular, synchronous push-and-plug connection with the first air supply pipe 206 and return pipe 205 of the air-cooled heat exchanger 204 on the cabinet 201 of the data cabinet 200, as well as the second air supply pipe 216 and pressure relief pipe 217 for transporting and depressurizing inert gas. This effectively improves the installation efficiency of the IT equipment 327 and the efficiency of the connection between the housing assembly 300 and the fire extinguishing and heat dissipation structures. The switching component 308 in the housing assembly 300 can cut off the supply of cold air and the return air recovery from the air-cooled heat exchanger 204 when a fire occurs within the IT equipment 327, while simultaneously connecting the gas storage tank 111 to supply inert gas. This allows the inert gas to be quickly filled into the housing assembly 300, achieving efficient fire extinguishing. In this invention, the cable retractor 330 inside the housing 301 of the housing assembly 300 can keep the data cable 351 and power cable 354 taut and retracted during the process of the IT device 327 entering and exiting the housing 301 without interfering with the movement of the IT device 327.

[0041] The operation flow of this invention is as follows: In the initial state, the cover assembly 300 is not installed inside the cabinet 201 of the data cabinet 200. The first positioning sleeve 211 in the first connecting assembly 207 protrudes from the end of the first branch pipe 208 under the action of the first spring 212 in a compressed state. The first valve ball 213 closes the first branch pipe 208. The two first baffles 322 on the housing 301 of the cover assembly 300 open the corresponding side first air holes 304. The two third ball valves close the two second connecting pipes 306. The second valve ball 221 in the second connecting assembly 218 closes the second branch pipe 219. The second positioning sleeve 228 in the second connecting assembly 218 protrudes from the end of the second branch pipe 219 under the action of the second spring 229 in a compressed state. The limiting block 227 at the end of the guide rod 226 abuts against the end of the ring sleeve 243. There is a small gap between the ring sleeve 243 and the second positioning sleeve 228. The two third valve balls 311 block the corresponding second connecting pipes 306. IT equipment 327 is installed inside housing 301. Two second baffles 355 in housing assembly 300 close the front opening of housing 301, and locking rod 366 is inserted into locking groove 367 to lock the two closed second baffles 355.

[0042] When the housing assembly 300 is installed into the cabinet 201, the housing 301 is horizontally inserted into the first guide rail 202 inside the cabinet 201. During the insertion of the housing 301 into the first guide rail 202, the two first racks 305 on both sides of the housing 301 simultaneously mesh with the first gears 242 of the corresponding layers of the first connecting assembly 207 on the return air pipe 205 and the first air supply pipe 206, driving the two first gears 242 to rotate. The first gears 242 in the first connecting assembly 207 drive the first valve ball 213 to rotate 90 degrees through the first pin 215. The first through hole 214 on the first valve ball 213 is opposite to the first branch pipe 208, making the first branch pipe 208 conductive. The inclined ends of the first connecting pipes 303 on the left and right sides of the housing 301 interact with the inclined ends of the first positioning sleeves 211 of the corresponding first connecting assembly 207, causing the first positioning sleeves 211 to slide along the first branch pipe 208 and compress the first spring 212. When the first connecting pipe 303 is fully inserted into the first positioning sleeve 211, the first connecting pipe 303 and the first branch pipe 208 are connected and pressurized to seal the first sealing gasket 210. Under the action of the first spring 212, the first positioning sleeve 211 slides back to its original position and is fitted onto the first connecting pipe 303, thereby ensuring that the first connecting pipe 303 and the first branch pipe 208 will not be misaligned due to vibration, and thus ensuring that the first connecting assembly 207 and the first connecting pipe 303 on the side wall of the housing 301 are effectively sealed and connected. The cold air generated by the air-cooled heat exchanger 204 passes through the first air supply pipe 206, the opened first connecting assembly 207, and the first connecting... The air inside the housing 301 enters through the pipe 303, the first vent 304, and the second vent 323 on the first baffle 322 to cool the IT equipment 327 installed inside the housing 301. The air inside the housing 301 returns to the air-cooled heat exchanger 204 through the second vent 323, the first vent 304, the first connecting pipe 303, the opened first connecting component 207, and the return pipe 205 under the negative pressure generated in the return pipe 205 of the air-cooled heat exchanger 204. This achieves air circulation and cooling inside the housing 301 on the one hand, and reduces the cooling efficiency of the air-cooled heat exchanger 204 on the other hand.

[0043] Meanwhile, the two second racks 307 on the rear side of the housing 301 mesh with the fourth gear 237 in the second connecting assembly 218 on the corresponding side of the second branch pipe 219 on the second air supply pipe 216 and the pressure relief pipe 217, and drive the fourth gear 237 to rotate. Under the action of the second racks 307, the fourth gear 237 in the second connecting assembly 218 drives the third gear 231 and the fifth gear 238 to rotate synchronously through the worm 234, the worm wheel 233 and the second rotating shaft 232. The fifth gear 238 drives the sixth gear 239, the third rotating shaft 240, the seventh gear 241 and the fifth gear 238 to rotate synchronously through the sixth gear 239, the third rotating shaft 240, the seventh gear 241 and the fifth gear 238. The second gear 224 and the second pin 223 drive the second valve ball 221 in the second connecting assembly 218 to rotate 90 degrees. The second through hole 222 on the second valve ball 221 communicates with the corresponding second branch pipe 219, thereby opening the second connecting assembly 218. At the same time, the third gear 231 drives the second positioning sleeve 228 to quickly connect with the second connecting pipe 306 via the gear ring 230, the ring sleeve 243, and the guide rod 226. The threading speed of the second positioning sleeve 228 and the second connecting pipe 306 is equal to the relative movement speed of the second connecting pipe 306 relative to the second branch pipe 219. The second sealing gasket 225 at the end of the second connecting pipe 306 and the second branch pipe 219 are pressed together to complete the docking. When the second connecting pipe 306 and the second positioning sleeve 228 begin to contact, if the threads of the second positioning sleeve 228 and the second connecting pipe 306 are not perfectly aligned, the second positioning sleeve 228 will compress the second spring 229, causing a slight axial displacement. When the threads on the rotating second positioning sleeve 228 align with the threads of the second connecting pipe 306, the second positioning sleeve 228 begins to screw into the second connecting pipe 306. When the second connecting pipe 306 and the second sealing gasket 225 at the end of the second branch pipe 219 form a compression fit, the second positioning sleeve 228 ensures that the connection between the second connecting pipe 306 and the second branch pipe 219 will not misalign or leak due to vibration.

[0044] When removing the housing assembly 300, manually move the first positioning sleeves 211 of the two first connecting assemblies 207 towards the first ball housing 209 to disengage them from the first connecting pipe 303. Then, pull the housing 301 outwards towards the first guide rail 202, causing the first connecting pipe 303 to disengage from the first branch pipe 208. During the outward pulling of the housing 301, the second rack 307 on the rear side of the housing 301 drives the second valve ball 221 and the second positioning sleeve 228 to rotate through a series of transmissions, causing the second valve ball 221 to automatically close to the second branch pipe 219 and causing the second positioning sleeve 228 to automatically rotate away from the second connecting pipe 306.

[0045] When a fire occurs in the IT equipment 327 inside the housing 301, the smoke detector 329 at the top of the housing 301 will cause the control system to control the second motor 317 to run. The second motor 317 drives the second valve ball 221 in the two second connecting pipes 306 to rotate 90 degrees through the ninth gear and the two fourth rotating shafts 313, so that the third through hole 312 on the second valve ball 221 is aligned with the second connecting pipe 306, thereby making the two second connecting pipes 306 conductive. At the same time, the two third valve balls 311 drive the two first baffles 322 to rotate 90 degrees through the corresponding third pin 314, the corresponding side first pulley 318, the first synchronous belt 319, the second pulley 320 and the fifth rotating shaft 321, respectively, so that the two first baffles 322 close the first vent 304 at the two first connecting pipes 303, thereby completing the switch of the housing 301 from the cooling and heat dissipation state to the fire extinguishing state. Inert gas in the second gas supply pipe 216 enters the housing 301 through the opened second connecting component 218, second connecting pipe 306, and third through hole 312 to surround the ignition point and isolate oxygen for fire extinguishing. At the same time, excess inert gas in the housing 301 is discharged into the compartment 101 through another second connecting pipe 306, second connecting component 218, and pressure relief pipe 217 to relieve pressure and prevent the housing 301 from exploding due to continuous inert gas filling.

[0046] When maintenance is required on the IT equipment 327 inside the housing 301, the torsion wheel 365 on the second baffle 355 is rotated. The torsion wheel 365 drives the locking rod 366 to disengage from the locking groove 367 through the fifth pin 364. Then, the torsion wheel 365 pulls the second baffle 355 outward. The second baffle 355 drives the other second baffle 355 to open synchronously through the synchronization component 357. Next, the IT device 327 is pulled outward, causing the mounting base 326 connected to it to move outward synchronously. At the same time, the mounting base 326 drives the thirteenth gear 343 in the two cable take-up assemblies 330 to rotate synchronously through the two fourth racks 344 on its lower side. The thirteenth gear 343 drives the tensioning wheel 350 on the slide 332 to move in the direction of loosening the power cable 354 or data cable 351 to adapt to the outward movement of the IT device 327 and keep the data cable 351 or power cable 354 taut. When the IT device 327 is pushed back into the housing 301, the cable retraction assembly 330 moves in the opposite direction to tighten and retract the slack in the power cable 354 or data cable 351 caused by the insertion of the IT device 327, ensuring that the power cable 354 and data cable 351 are not squeezed or interfered with by the movement of the IT device 327.

[0047] After the IT device 327 is pushed back into the housing 301, the second baffle 355 is closed by the torsion wheel 365. The second baffle 355 drives the other second baffle 355 to close synchronously through the synchronization component 357. After the two second baffles 355 are completely closed, the torsion wheel 365 is rotated. The torsion wheel 365 drives the locking rod 366 to insert into the locking groove 367 through the fifth pin 364 to complete the locking of the two second baffles 355.
