Description

Technical Field

[0001] This utility model relates to the field of ventilated floor technology, specifically to a ventilated floor with adjustable ventilation volume for computer rooms. Background Technology

[0002] As locations where high-density electronic equipment operates, computer rooms (such as server rooms or data centers) require strictly controlled physical environments. These environments primarily include temperature, power supply, flooring, and fire protection systems. Existing server rooms typically control temperature and humidity through air conditioning systems. The Refrigeration and Air-Conditioning Engineering Society's "Thermal Guidelines for Data Processing Environments" recommends a temperature range of 20°C-25°C for server rooms. Within a server room, the power supply generates significant heat. If this heat is not dissipated promptly, the temperature will rise rapidly, potentially causing electronic equipment malfunctions. To ensure stable operation, server rooms are typically equipped with ventilated floors. These floors facilitate the delivery of cool air from the air conditioning system into the server room and ensure even airflow distribution.

[0003] However, existing ventilated floors for computer rooms have a fixed airflow rate, which cannot be adjusted according to actual needs. The heat dissipation requirements of different areas within a computer room may vary due to equipment density, operating status, or environmental conditions. A fixed-airflow ventilated floor cannot meet these diverse heat dissipation requirements, leading to either excessive cooling resulting in energy waste or insufficient cooling due to insufficient airflow. Therefore, there is an urgent need for an adjustable-airflow ventilated floor for computer rooms to solve these problems. Utility Model Content

[0004] To address the technical problem that the ventilation volume of existing computer room ventilation floors is fixed, this utility model provides a computer room ventilation floor with adjustable ventilation volume. The overall structure is simple, the sealing plate is easy to operate, and according to the different heat dissipation requirements of electronic equipment in different computer rooms, multiple ventilation holes can be used for ventilation, or only some ventilation holes can be selected for ventilation, ultimately achieving adjustable ventilation volume.

[0005] This utility model provides an adjustable ventilation floor for computer rooms, comprising a support frame, a main ventilation board, and multiple sealing plates. The main ventilation board is fixedly mounted on the support frame, and the multiple sealing plates are slidably mounted on the support frame, arranged sequentially along the length of the support frame. The multiple sealing plates are located below and in contact with the main ventilation board. The main ventilation board has multiple ventilation holes evenly distributed on it, and the sealing plates are located directly below and seal the ventilation holes in the same row. The support frame supports the main ventilation board and the multiple sealing plates.

[0006] Furthermore, two opposing sliding rods are fixedly arranged on both sides of the support frame, and the sliding rods are arranged along the length direction of the support frame. Each sealing plate has a sliding sleeve fixedly arranged at both ends. The two sliding sleeves on each sealing plate are respectively fitted onto the two sliding rods and can slide. The sliding sleeves slide on the sliding rods, and the sealing plate then slides relative to the two sliding rods. When the sealing plate is located directly below and seals the multiple ventilation holes in the same column, the sliding sleeves will no longer slide.

[0007] Furthermore, each of the sliding rods is evenly provided with a plurality of first pin holes, and each of the sliding sleeves is provided with two opposing third pin holes. The pin passes through the first pin holes on the sliding rods and the two first pin holes on the sliding sleeves. The pin keeps the sliding sleeve stable on the sliding rods, thereby stabilizing the sealing plate on the two sliding rods. When it is necessary to adjust the position of the sealing plate, the pin can be removed from the sliding sleeve to allow it to slide on the sliding rods.

[0008] Furthermore, each of the sliding sleeves is fixedly provided with a pull ring on its exterior. A person can pull the sliding sleeve on the sliding rod by pulling the pull ring, which further facilitates manual operation of the sliding sleeve.

[0009] Furthermore, the ventilated floor also includes an air-gathering hood fixedly mounted on the support frame. The air-gathering hood covers the main ventilation board. A partition is fixedly mounted inside the air-gathering hood, dividing the interior into a first and a second interconnected region. The first region communicates with ventilation holes. Inside the air-gathering hood, a guide plate and two arc-shaped plates are fixedly mounted within the second region. The guide plate is located between the two arc-shaped plates, forming a flow channel between the guide plate and each arc-shaped plate. The top of the air-gathering hood has multiple air-distributing holes communicating with the flow channels. When cold air passes through the air-gathering hood, it is first gathered in the flow channels, and then evenly blown out through the air-distributing holes.

[0010] Furthermore, fixing blocks are fixedly installed at the four corners of the top of the support frame, and L-shaped grooves are provided on the fixing blocks. Inverted L-shaped protrusions are fixedly installed at the four corners of the ventilation main board, and the inverted L-shaped protrusions are engaged in the L-shaped grooves. The inverted L-shaped protrusions engaging in the L-shaped grooves fix the ventilation main board on the support frame and keep it stable.

[0011] Furthermore, each of the four corners of the bottom of the support frame is provided with a telescopic support foot. Each telescopic support foot includes a support frame and a support block fixedly mounted on the support frame. A stud is rotatably mounted on the support block, and the stud passes through the support block. A rotating handwheel is fixedly mounted at the bottom of the stud, and the top of the stud is fixedly connected to the end corner of the bottom of the support frame. When the handwheel is manually rotated, the stud rotates, and after the stud rotates, it moves up and down relative to the support block. Moving the stud up or down moves the support frame up or down, thereby adjusting the height of the support frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The ventilated floor provided by this utility model has a simple overall structure and convenient operation of the sealing plate. According to the different heat dissipation requirements of electronic equipment in different computer rooms, all of the multiple ventilation holes can be used for ventilation, or only some ventilation holes can be selected for ventilation, ultimately achieving adjustable ventilation volume.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-5 As shown, a ventilated floor with adjustable ventilation for computer rooms includes a support frame 1, a main ventilation board 2, and multiple sealing plates 3. The main ventilation board 2 is fixedly mounted on the support frame 1. The multiple sealing plates 3 are slidably mounted on the support frame 1 and are arranged sequentially along the length of the support frame 1. The multiple sealing plates 3 are located below and in contact with the main ventilation board 2. The main ventilation board 2 has multiple ventilation holes 21 evenly distributed on it. The sealing plates 3 are located directly below the ventilation holes 21 in the same row and seal them. The support frame 1 supports the main ventilation board 2 and the multiple sealing plates 3. The multiple sealing plates 3 can be completely unused or partially used. Of course, when the sealing plates 3 are unused or partially used, the unused sealing plates 3 will slide and be fixed to one side of the ventilation holes 21, thus not affecting the ventilation of the ventilation holes 21. When all the sealing plates 3 are unused, the ventilation volume of the ventilated floor is at its maximum. Generally, the position of the sealing plates 3 is adjusted before the ventilated floor is used in the computer room; different computer rooms can adjust the position of the sealing plates 3 as needed according to their respective heat dissipation requirements.

[0027] In this embodiment, when the ventilated floor is in use, the cold air from the air conditioning system is delivered to the area below the ventilation main board 2 through external pipes. The cold air passes through multiple ventilation holes 21 on the ventilation main board 2 and is evenly blown into the computer room, thereby cooling and dissipating heat from the electronic equipment in the computer room.

[0028] Electronic devices in different areas of different computer rooms generate varying amounts of heat, thus requiring different ventilation volumes for cooling. To avoid energy waste from excessive cooling or insufficient cooling from insufficient cooling, the position of the sealing plate 3 is manually adjusted according to the cooling needs of the electronic devices. The sealing plate 3 slides on the support frame 1 and is then fixed in place on the support frame 1. The sealing plate 3 is positioned directly below and seals the multiple ventilation holes 21 in the same column. It should be noted that the sealing plate 3 can completely seal the multiple ventilation holes 21 in the same column, or it can partially seal each ventilation hole 21 in the same column, for example, sealing one-third of the area of ​​each ventilation hole 21 in the same column. After the sealing plate 3 seals the multiple ventilation holes 21 in the same column, the cooling air only passes through the unsealed ventilation holes 21 on the main ventilation board 2, ensuring uniform ventilation evenly despite a reduced ventilation volume. See also Figure 2 Only the multiple ventilation holes 21 in the fourth column provide ventilation, at which point the ventilation volume of the ventilated floor is relatively small.

[0029] The ventilation floor in this embodiment has a simple overall structure and the sealing plate 3 is easy to operate. According to the different heat dissipation requirements of electronic equipment in different computer rooms, all of the multiple ventilation holes 21 can be used for ventilation, or only some ventilation holes 21 can be selected for ventilation, thus achieving adjustable ventilation volume.

[0030] In one possible implementation, two opposing sliding rods 11 are fixedly arranged on both sides of the support frame 1, and the sliding rods 11 are arranged along the length direction of the support frame 1. Each sealing plate 3 has a sliding sleeve 31 fixedly arranged at both ends. The two sliding sleeves 31 on each sealing plate 3 are respectively fitted onto the two sliding rods 11 and can slide. When no external force is applied, the sliding sleeves 31 do not slide. According to the heat dissipation requirements of the electronic device, the position of the sealing plate 3 is manually adjusted. Based on the arrangement of multiple sealing plates 3, the sliding sleeves 31 on the sealing plate 3 are manually slid. The sliding sleeves 31 slide on the sliding rods 11, and the sealing plate 3 then slides relative to the two sliding rods 11. When the sealing plate 3 is located directly below multiple ventilation holes 21 in the same column and seals all or part of its area, the sliding sleeves 31 stop sliding. Repeating the above process allows for the adjustment of the position of multiple sealing plates 3 to meet different heat dissipation requirements.

[0031] In one possible implementation, each slide rod 11 is provided with a plurality of first pin holes evenly distributed, and each slide sleeve 31 is provided with two opposing third pin holes. A pin passes through the first pin holes on the slide rod 11 and the two first pin holes on the slide sleeve 31. The pin keeps the slide sleeve 31 stable on the slide rod 11, thereby stabilizing the sealing plate 3 on the two slide rods 11. When the position of the sealing plate 3 needs to be adjusted, the pin is removed, and the slide sleeve 31 can then slide on the slide rod 11.

[0032] As one possible implementation, each of the sliding sleeves 31 is fixedly provided with a pull ring 32 on its exterior. A person can pull the sliding sleeve 31 on the sliding rod 11 by pulling the pull ring 32, which further facilitates the manual operation of the sliding sleeve 31.

[0033] As one possible implementation, the ventilated floor further includes a concentrator hood 4 fixedly mounted on the support frame 1. The concentrator hood 4 has an inverted U-shaped cross-section and covers the main ventilation board 2. A partition 41 is fixedly mounted inside the concentrator hood 4, dividing the interior of the concentrator hood 4 into a first region and a second region that are connected. The two sides of the partition 41 are fixedly connected to the side walls of the concentrator hood 4, and the two ends of the partition 41 form a gap connecting the first region and the second region with the side walls of the concentrator hood 4. The first region is connected to the ventilation hole 21. A guide plate 42 and two arc-shaped plates 43 are fixedly mounted inside the concentrator hood 4 in the second region. The guide plate 42 is located in the middle of the two arc-shaped plates 43, and a flow channel is formed between the guide plate 42 and each arc-shaped plate 43. A plurality of air distribution holes 44 communicating with the flow channels are provided on the top of the concentrator hood 4. After passing through the unsealed ventilation holes 21 or all ventilation holes 21 on the ventilation main board 2, the cold air enters the flow channel of the second area through the first region and the gap. The cold air is then blown out through the flow channel from multiple air distribution holes 44. When the cold air passes through the air concentrator 4, the cold air is first gathered in the flow channel, and then the cold air is blown out evenly through the air distribution holes 44.

[0034] When installing a ventilated floor in a computer room, the air distribution holes 44 are aligned with the part of the electronic equipment that generates the most heat. The air concentrator shroud 4 concentrates and evenly directs cool air towards the part of the electronic equipment that generates the most heat, thereby accelerating the cooling efficiency of the electronic equipment. The ventilated floor not only allows for adjustable ventilation volume but also concentrates and evenly directs cool air towards the part of the electronic equipment that generates the most heat.

[0035] Preferably, the length of the guide plate 42 is less than the length of the arc plate 43, so that the flow rate of the cold air can remain uniform when the cold air enters the flow channel, thereby making the cold air blow out more evenly from the multiple air distribution holes 44.

[0036] In one possible implementation, the support frame 1 is provided with a first fixing hole, and the wind concentrator 4 is provided with a second fixing hole. Bolts pass through the first and second fixing holes and are fixedly connected with nuts. The wind concentrator 4 is fixed to the support frame 1 by bolts and nuts.

[0037] In one possible implementation, fixing blocks 12 are fixedly provided at each of the four corners of the top of the support frame 1. Each fixing block 12 has an L-shaped groove. Inverted L-shaped protrusions 22 are fixedly provided at each of the four corners of the ventilation main board 2. These inverted L-shaped protrusions 22 engage with the L-shaped grooves. The engagement of the inverted L-shaped protrusions 22 with the L-shaped grooves ensures that the ventilation main board 2 is fixed to the support frame 1 and remains stable.

[0038] In one possible implementation, each of the four corners of the bottom of the support frame 1 is provided with a telescopic support foot 5. Each telescopic support foot 5 includes a support frame 51 and a support block 52 fixedly mounted on the support frame 51. A stud 53 is rotatably mounted on the support block 52 and passes through the support block 52. A screw hole is provided through the support block 52, and the stud 53 passes through the screw hole and rotates relative to the screw hole. A rotating handwheel 54 is fixedly mounted at the bottom of the stud 53, and the top of the stud 53 is fixedly connected to the end corner of the bottom of the support frame 1. When the person manually rotates the rotating handwheel 54, the stud 53 rotates. After the stud 53 rotates, it actually moves up and down relative to the support block 52. The stud 53 moves up or down, thereby moving the support frame 1 up or down, thus adjusting the height of the support frame 1. That is, the height of the ventilation main plate 2 and multiple sealing plates 3 on the support frame 1 can be adjusted, ultimately achieving adjustable ventilation height of the ventilated floor. Adjust the ventilation height of the ventilated floor according to the heat dissipation requirements of electronic devices, so that the ventilated floor is positioned closer to the electronic devices, thereby accelerating the heat dissipation efficiency of the electronic devices.

They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of this utility model should be included within the scope of the patent application of this utility model.
