Description

Technical Field

[0001] This invention relates to the field of cabinet heat dissipation technology, specifically to an emergency heat dissipation device for data center cabinets. Background Technology

[0002] Patent application CN220755297U includes a housing, an air conditioner, at least two sensors, and a control device. The housing encloses an installation space for mounting a data module and has at least two vents connecting the installation space to the outside. The air conditioner blows air into the housing. A sensor is located at one of the vents and is used to acquire airflow parameters. The control device is electrically connected to the air conditioner and the sensors, and controls the air conditioner to adjust its fan speed based on the airflow parameters obtained from the multiple sensors. Sensors are used to measure relevant parameters of the airflow inside the vents on the housing. The control device adjusts the air conditioner's fan speed by comparing the measured parameters with set values. The air conditioner's fan speed affects the internal airflow velocity of the data cabinet, thereby changing the internal pressure. Maintaining a small-range stable internal pressure within the data cabinet protects the normal operating environment of the equipment.

[0003] In the aforementioned patents, some existing cabinet cooling systems rely on continuous power and the normal operation of the control system. In practical applications, when a data center encounters a sudden power outage, air conditioning system failure, or control device failure, the active cooling function will not be able to start or be maintained. The temperature inside the cabinet will rise sharply due to the continuous operation of the equipment, which may lead to overheating and frequency reduction, downtime, or even hardware damage, resulting in data loss and business interruption. Summary of the Invention

[0004] The purpose of this invention is to provide an emergency cooling device for data center cabinets to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an emergency heat dissipation device for data center cabinets, including a cabinet mechanism and an installation mechanism disposed on the cabinet mechanism. A heat dissipation base mechanism is disposed below the cabinet mechanism. The heat dissipation base mechanism includes a base assembly disposed below the cabinet mechanism. A connecting component is disposed inside the lower part of the base assembly. A fixing component is disposed above the connecting component. A driving component and a guiding component are disposed inside the lower part of the base assembly. The base assembly includes a base housing disposed below the cabinet mechanism, the base housing having first connecting grooves on both sides, a plurality of second connecting holes on the top of the base housing, and a first fixing hole on the top of the base housing.

[0006] Preferably, the connecting assembly includes L-shaped plates that are slidably disposed in two first connecting slots, guide blocks that are fixedly connected to opposite sides of the two L-shaped plates, connecting horizontal plates that are fixedly connected to the lower side of opposite sides of the two L-shaped plates, a limit rod that is fixedly connected to the lower part of the base housing, and a limit groove that corresponds to the limit rod on each of the two connecting horizontal plates.

[0007] Preferably, the drive assembly includes a connecting crossbar disposed within the base housing. A connecting long tube is fixedly connected to the upper end of the connecting crossbar, and the connecting long tube corresponds to the position of the first fixing hole. The connecting long tube is fixedly connected within the first fixing hole. A sliding long groove is formed inside the connecting crossbar, and a fixing plate is fixedly connected inside the sliding long groove. First springs are fixedly connected to both sides of the fixing plate, and connecting slide rods are fixedly connected to the other ends of the two first springs.

[0008] Preferably, the connecting slide rod is slidably disposed in the sliding groove, and the other ends of the two connecting slide rods are respectively fixedly connected to one side of the two guide blocks.

[0009] Preferably, the guide assembly includes a fixed column disposed within the base housing, a sliding cavity being formed within the fixed column, two sliding columns being slidably connected within the sliding cavity of the fixed column, a support rod being fixedly connected to the outside of the fixed column, and the other end of the support rod being fixedly connected to the inner wall of the base housing.

[0010] Preferably, one end of each of the two sliding columns is fixedly connected to one side of the guide block.

[0011] Preferably, the fixing component includes a connecting frame fixedly connected to the upper part of the base housing, two connecting vertical plates fixedly connected below the connecting frame, a second fixing hole corresponding to the connecting long tube on the connecting frame, mounting shells fixedly connected between the two ends of the two connecting vertical plates, and a triangular block fixedly connected between the two connecting vertical plates, the triangular block being located between the two mounting shells.

[0012] Preferably, the cabinet mechanism includes a cabinet, the cabinet having two first connecting holes and a connecting circular hole located between the two first connecting holes, and multiple C-shaped tubes fixedly installed on both sides of the cabinet.

[0013] Preferably, the installation mechanism includes a fixed shell fixedly connected to the upper end of the cabinet. The fixed shell has a second connecting groove and two recesses below it, with the second connecting groove located between the two recesses. The fixed shell has a connecting groove at the top inside, which is connected to the second connecting groove and the recesses. A partition assembly is provided in the recess, and two sliding grooves are provided on both sides of the inner wall of the recess.

[0014] Preferably, the partition assembly includes a sliding partition that is slidably disposed in the groove, with two sliding blocks fixedly connected to each end of the sliding partition, and a second spring fixedly connected above the sliding partition, the other end of which is fixedly connected to the upper part of the communicating groove.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) By setting up an installation mechanism and drive components, this application realizes the effect of automatically opening the heat dissipation channel as the temperature inside the cabinet rises. When the temperature inside the cabinet rises, hot air enters the groove through the first connecting hole, which increases the air pressure inside the groove and overcomes the elastic force of the second spring, pushing the sliding partition upward. The partition compresses the gas in the connecting groove and the groove and enters the sliding groove through the connecting long pipe. Then it pushes the connecting slide rod, guide block and L-shaped plate to slide outward, automatically opening the first connecting groove to form a heat dissipation channel. This method does not require external sensors or electrical control. It relies entirely on the abnormal temperature inside the cabinet to automatically trigger the response. It has a timely response and a low failure rate. Moreover, the channel can be kept closed at room temperature, which can prevent dust from entering the cabinet and affecting the operation of the internal equipment, thus improving the energy efficiency and stability of the equipment. (2) When the hot air inside the cabinet is discharged through the fan assembly installed in the housing, the airflow is guided to the C-shaped tubes on both sides of the cabinet by the guide block, so that the airflow flows upward along the C-shaped tubes and carries away the heat on the outer wall of the cabinet. The heat dissipation fins on the outside of the cabinet increase the heat dissipation area, so that the air carries away more heat when it flows in the C-shaped tubes, achieving the effect of simultaneous heat dissipation inside and outside. In addition, the C-shaped tubes discharge the hot air from the top of the C-shaped tubes, preventing the situation of horizontal exhaust of traditional heat dissipation devices. This can avoid the high temperature airflow from blowing directly to adjacent cabinets or other equipment, and prevent the problem of the working environment of other equipment deteriorating and the temperature rising abnormally due to the hot air entering other equipment. It is particularly suitable for the layout of data center cabinets with high density deployment, and significantly improves the heat dissipation safety and environmental adaptability of the overall system.

[0027] The cabinet mechanism 1 includes a cabinet 11, which has two first connecting holes 12 and a connecting round hole 13 located between the two first connecting holes 12. The second connecting hole 213 is connected to the interior of the cabinet 11. Multiple C-shaped tubes 14 are fixedly installed on both sides of the cabinet 11. The C-shaped tubes 14 and the outside of the cabinet 11 form an air duct. Heat dissipation fins are installed on the outside of the cabinet 11 at positions corresponding to the C-shaped tubes 14.

[0028] The mounting mechanism 3 includes a fixed shell 31 fixedly connected to the upper end of the cabinet 11. A second connecting groove 32 and two grooves 33 are provided below the fixed shell 31, and the second connecting groove 32 is located between the two grooves 33. A connecting groove 34 is provided inside the upper part of the fixed shell 31. The connecting groove 34 is connected to the second connecting groove 32 and the grooves 33. A partition assembly 35 is provided in the groove 33. Two sliding grooves 331 are provided on both sides of the inner wall of the groove 33. The second connecting groove 32 corresponds to the position of the connecting long tube 243 and the connecting round hole 13. The first connecting hole 12 corresponds to the position of the groove 33.

[0029] The partition assembly 35 includes a sliding partition 351 that is slidably disposed in the groove 33. Two sliding blocks 352 are fixedly connected to both ends of the sliding partition 351. A second spring 353 is fixedly connected above the sliding partition 351. The other end of the second spring 353 is fixedly connected to the upper part of the communicating groove 34.

[0030] The working principle of the present invention is as follows: During use, when the cabinet 11 is at room temperature, in the partition assembly 35 of the installation mechanism 3, the sliding partition 351 is located below the groove 33 under the elastic force of the second spring 353. In the drive assembly 24, the connecting slide rod 246 is in a retracted state under the action of the first spring 245. In the connecting assembly 22, the L-shaped plate 221 is located in the first connecting groove 212, the two side sealing plates are in a closed state, the first connecting grooves 212 on both sides of the base housing 211 are blocked by the L-shaped plate 221, and the heat dissipation channel is not opened. When the internal temperature of the cabinet mechanism 1 rises, hot air rises and accumulates above the inside of the cabinet 11. The hot air enters the groove 33 of the mounting mechanism 3 through the first connecting hole 12 on the cabinet 11. The hot air in the groove 33 expands due to heat, increasing the pressure. The increased air pressure overcomes the elastic force of the second spring 353, pushing the sliding partition 351 to slide upward. The sliding blocks 352 at both ends of the sliding partition 351 guide the sliding within the sliding groove 331, ensuring the smooth movement of the sliding partition 351. When the sliding partition 351 slides upward, it compresses the gas in the connecting groove 34 and the second connecting groove 32. The compressed gas enters the connecting long tube 243 through the connecting round hole 13. The compressed gas enters the sliding long groove 242 in the connecting crossbar 241 along the connecting long tube 243. The air pressure in the sliding long groove 242 increases, pushing the connecting slide rods 246 on both sides to slide outward. The connecting slide rods 246 overcome the tension of the first spring 245 and slide along the sliding long groove 242. Extending outward, the connecting slide rod 246 pushes the guide inclined block 222 to move. The guide inclined block 222 drives the L-shaped plate 221 to slide outward along the first connecting groove 212. The sliding of the L-shaped plate 221 is guided and limited by the cooperation of the limiting rod 225 and the limiting slide groove 224 to ensure stable movement. At the same time, the sliding column 253 in the guide assembly 25 slides in the fixed column 251 to ensure the stable displacement of the L-shaped plate 221. At this time, the first connecting grooves 212 on both sides of the base housing 211 are opened to form a heat dissipation channel. When the L-shaped plate 221 is opened, the fan assembly in the fixed assembly 23 starts and draws the airflow in the cabinet 11 into the connecting frame 231 through the second connecting hole 213. Then, the airflow enters the mounting shell 234 from the connecting frame 231. The fan assembly in the mounting shell 234 blows the air toward the guide inclined block 222 and discharges it out of the cabinet 11 through the opened first connecting groove 212, so that the hot air in the cabinet 11 is discharged.

[0031] When the gas is blown from the first connecting groove 212 toward the inclined block 222, the gas is guided by the inclined block 222 to the C-shaped tube 14. The gas passes through the C-shaped tube 14, and at this time the airflow will carry away the heat on the outside of the cabinet 11 and discharge it from the top of the C-shaped tube 14, preventing the horizontally discharged hot air from entering other equipment and causing other equipment to have abnormal high temperature. The heat dissipation fins on the outside of the cabinet 11 increase the heat dissipation area, thereby increasing the heat dissipation effect. When the temperature inside the cabinet 11 drops, the gas temperature in the groove 33 decreases and the pressure decreases. The elastic force of the second spring 353 is greater than the gas pressure, pushing the sliding partition 351 to reset downwards. The pressure in the connecting groove 34 and the second connecting groove 32 decreases. The first spring 245 pulls the connecting slide rod 246 to retract and reset in the sliding long groove 242. The connecting slide rod 246 drives the guide inclined block 222 and the L-shaped plate 221 to slide inwards and reset. The L-shaped plate 221 re-closes the first connecting groove 212, and the heat dissipation channel is closed. At this time, the fan assembly in the mounting shell 234 stops working.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
