Description

Technical Field

[0001] The utility model belongs to the field of air supply devices, in particular to an air supply device for an air conditioner in a double-cold-source machine room. Background Art

[0002] With the rapid development of information technology, modern electronic equipment rooms are becoming more and more common. These electronic equipment rooms include communication centers, IDC data centers, computer centers, power protection rooms, and inverter rooms. Placing these devices in the room leads to a large number of densely packed electronic devices in the room, and the equipment in the room generates a lot of heat. However, due to the working characteristics of electronic components, there are very strict requirements for the room environment, and a certain temperature needs to be maintained around the clock. That is, the temperature of the electronic equipment room needs to be controlled at a high level to improve the life and reliability of the electronic equipment. Traditional single-cold source rooms are difficult to meet the temperature control requirements in the room. Now dual-cold source air conditioners are often used to adjust the room temperature, such as air cooling, chilled water system or water cooling, chilled water system air conditioners.

[0003] However, when the dual-cold-source air conditioner is supplying air, the wind is blown out directly from the air outlet of the air conditioner under the action of the internal fan, resulting in a large difference in temperature between the area near the air outlet and the area far from the air outlet, making it difficult to maintain a constant temperature in the computer room and to ensure consistent cooling and heating for all equipment in the computer room. One disadvantage of the dual-cold-source air conditioner when supplying air is that when the computer room is large, the air circulation speed of the air delivered is slow in the computer room. Another disadvantage is that the air delivered is not gentle enough. The strong wind blows directly onto the device in the computer room, causing a large temperature change in the device, which will have a negative impact on the electronic components and mechanical structure of the device, such as causing the solder joints of the circuit board to fall off and the aging and cracking of plastic parts. The patent with application number CN202121986348.4 provides a balanced air supply duct in an industrial air-conditioning warehouse. The balanced air supply duct in the industrial air-conditioning warehouse can pass through the tapered air supply tail pipe at the tail end of the air supply duct mechanism, which can increase the pressure of the air supply tail pipe part, thereby increasing the wind force at the air outlet at the air supply tail pipe, and achieving the purpose of balanced air supply. However, in the prior art, the length of the air supply duct is fixed, and it needs to be adjusted according to the actual length of the machine room during installation. After the air supply duct is installed, it is relatively cumbersome to increase or decrease the length of the air supply duct, which requires installation and removal operations, and is time-consuming and labor-intensive.

[0004] In order to solve the deficiencies of the prior art, the present application provides an air-conditioning air supply device that supplies air evenly and can adjust the length of the air supply duct.

[0005] The utility model discloses an air-conditioning air supply device under a double-cold-source machine room, the air-conditioning air supply device comprises an air supply member, a first air supply duct and a second air supply duct, the air supply member comprises an air supply member air outlet and an air supply member air inlet, both ends of the first air supply duct are open, one end of the first air supply duct is connected to the air supply member air outlet, a plurality of vents are arranged on the first air supply duct at intervals, the sizes of the vents increase successively from the air supply member air outlet toward the first air supply duct, a track is arranged on the outer side of the first air supply duct, a second air supply duct, one end of the second air supply duct is open, one end of the opening of the second air supply duct is slidably connected to the first air supply duct through the track, and a plurality of vents are arranged on the second air supply duct at intervals.

[0006] Furthermore, the size of the vent on the second air supply duct is larger than the size of the vent on the first air supply duct.

[0007] Furthermore, a limiting portion for limiting the movement of the second air supply duct is provided on the track.

[0008] Furthermore, the air-conditioning air supply device includes a vent switch, and the vent switch is arranged near the vent.

[0013] Furthermore, the materials of the first air supply duct and the second air supply duct include one or more combinations of polyurethane, rubber-plastic sponge, composite silicate or aluminum silicate.

[0014] The air conditioning air supply device of the present application increases the circulation and ventilation effect of air by accelerating the air flow through the air supply member. When the air-conditioning wind passes through the air supply member, the air supply member will blow the air to a wider area in the first air supply duct and the second air supply duct, thereby increasing the circulation and circulation of the air.

[0021] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the specific implementation manner of the utility model will be clearly and completely described below.

[0022] In order to solve the deficiencies of the prior art, the present application discloses an air conditioning and air supply device 100 under a dual cold source machine room, such as Figure 1As shown, the air-conditioning air supply device 100 includes an air supply member 11, a first air supply duct 12 and a second air supply duct 13. The air supply member 11 includes an air outlet of the air supply member 11 and an air inlet of the air supply member 11. The air supply member 11 is used to supply and guide air to enhance air flow. The air blown out of the air conditioner can enter the air supply member 11 through the air inlet of the air supply member 11. The air supply member 11 can enhance the wind force blown out of the air conditioner and blow the wind to a farther location. Both ends of the first air supply duct 12 are open, and one end of the first air supply duct 12 is connected to the air outlet of the air supply member 11. Figure 2 As shown, a plurality of vents are arranged at intervals on the first air supply duct 12, and the air supply member 11 guides the air from the air outlet of the air supply member 11 into the first air supply duct 12, and discharges the air through the vents on the first air supply duct 12, so that the temperature in the machine room is more uniform. The size of the vents increases in sequence from the air outlet of the air supply member 11 at one end of the air supply member 11 to the first air supply duct 12, and the cold air or hot air is first discharged from the smaller vents, and then discharged from the larger exhaust after advancing one end. Through such an arrangement, the air volume discharged from the vents in the first air supply duct 12 can be similar, further improving the air guide uniformity of the air conditioning air supply device 100. A track is arranged on the outer side of the first air supply duct 12. One end of the second air supply duct 13 is open, and the open end of the second air supply duct 13 is slidably connected to the first air supply duct 12 through a track, and a plurality of vents are arranged at intervals on the second air supply duct 13. The present application sets a track on the outside of the first air supply duct 12, and the second air supply duct 13 is slidably connected to the first air supply duct 12 through the track. The second air supply duct 13 can be slidably adjusted when the air-conditioning air supply device 100 is in use, and the air-conditioned air is discharged through the vents on the second air supply duct 13, thereby increasing the exhaust range of the air-conditioning air supply device 100. The second air supply duct 13 is slidably connected to the first air supply duct 12, and can be adjusted according to the actual use length of the machine room when in use, thereby increasing the exhaust range of the air-conditioning air supply device 100, facilitating installation in machine room spaces of various lengths, and adjusting the length of the air-conditioning air supply device 100 according to the length of the machine room, so as to make the temperature of the machine room uniform to the greatest extent. The second air supply duct 13 may not be completely pulled out of the first air supply duct 12 when in use, and can be set as needed. When the second air supply duct 13 is pulled out, the vents on the second air supply duct 13 are aligned with the vents on the first air supply duct 12, so that the exhaust of the first air supply duct 12 is not affected when the second air supply duct 13 is in use. Figure 3As shown, when the second air supply duct 13 is not in use, the vents on the second air supply duct 13 can be aligned with the vents on the first air supply duct 12. Such an arrangement does not affect the ventilation of the first air supply duct 12 when the air-conditioning air supply device 100 does not use the second air supply duct 13. After the air supply member 11 strengthens the wind in the air conditioner, the wind will move quickly in the air-conditioning air supply device 100 and be discharged through the vents, thereby increasing the uniformity of the air supply of the air conditioner. The air-conditioning air supply device 100 of the present application accelerates the air flow through the air supply member 11 to increase the circulation and ventilation effect of the air, thereby increasing the circulation and circulation of the air. The present application sets a plurality of vents that increase in sequence on the air supply duct, and the cold air or hot air is first discharged from the smaller vents, and then discharged from the larger exhaust air after advancing one end distance, so that the air volume discharged from the vents in the first air supply duct 12 is similar in size, thereby enhancing the uniformity of the temperature in the machine room. The present application sets a first air supply duct 12 and a second air supply duct 13 , and the length of the air conditioning and air supply device 100 can be adjusted through the second air supply duct 13 , so as to adapt to machine rooms with various length settings and increase the applicability of the air conditioning and air supply device 100 .

[0023] As an implementation mode, on the one hand, when the second air supply duct 13 is not in use, the ventilation holes on the second air supply duct 13 need to be aligned with the ventilation holes on the first air supply duct 12, and the size of the ventilation holes on the second air supply duct 13 is set to be larger than the size of the ventilation holes on the first air supply duct to prevent the second air supply duct 13 from affecting the exhaust of the first air supply duct 12. On the other hand, when the second air supply duct 13 is in use, if the ventilation holes on the second air supply duct 13 are smaller than the ventilation holes on the first air supply duct 12, the air conditioning air will be mostly discharged from the ventilation holes on the first air supply duct 12 close to the air conditioning outlet, which will cause the air conditioning air supply device 100 to supply air to the machine room unevenly. By setting the size of the ventilation holes on the second air supply duct 13 to be larger than the size of the ventilation holes on the first air supply duct, the air supply uniformity of the air conditioning air supply device 100 can be ensured when the second air supply duct 13 is in use.

[0024] As an embodiment, the second air supply duct 13 is connected to the first air supply duct 12 by sliding on a track. When the second air supply duct 13 slides on the first air supply duct 12, on the one hand, when the second air supply duct 13 is close to the air supply member 11, it is necessary to ensure that the vents on the second air supply duct 13 are aligned with the vents on the first air supply duct 12. On the other hand, when the second air supply duct 13 is away from the air supply member 11, it is necessary to prevent the second air supply duct 13 from falling off from the first air supply duct 12. The present application provides a limiting portion 121 on the track to limit the movement of the second air supply duct 13, thereby preventing the second air supply duct 13 from falling off from the first air supply duct 12 and ensuring that the vents on the second air supply duct 13 are aligned with the vents on the first air supply duct 12 when the second air supply duct 13 is close to the air supply member 11. The portability and reliability of the air-conditioning air supply device 100 are increased.

[0025] As an implementation mode, the first air supply duct 12 and the second air supply duct 13 respectively include a plurality of vents, and the air enhanced by the air supply member 11 is discharged through the vents. When the air conditioning and air supply device 100 is used to adjust the temperature in the machine room, some locations may require stronger air conditioning air for temperature adjustment, and some locations may not require air conditioning air to blow all the time. A vent switch 14 is provided on the vent. After the air conditioning and air supply device 100 adjusts the temperature in the machine room to be consistent, the vent switch 14 can be used to reduce or completely close the vents that are not wanted.

[0026] As an implementation method, a filter is provided at the vent. The filter can filter out dust and bacteria in the air and improve the air quality of the machine room. The filter can prevent dust and impurities from entering the air-conditioning air supply device 100, protect the internal parts of the air-conditioning air supply device 100, and extend the service life of the air-conditioning air supply device 100. The filter can reduce the noise during air flow and improve the comfort of using the air-conditioning air supply device 100.

[0027] As an implementation method, Figure 4 and Figure 5 As shown, the air-conditioning and air-supplying device 100 can be arranged in the upper part of the machine room in order to prevent it from occupying too much space when in use. The air-conditioning and air-supplying device 100 is provided with a plurality of recessed fixing parts 1515 on the outer sides of the first air supply duct 12 and the second air supply duct 13. The air-conditioning and air-supplying device 100 can be hung and fixed in the upper part of the machine room by the plurality of recessed fixing parts 15 on the outer sides of the first air supply duct 12 and the second air supply duct 13.

[0028] As an implementation method, the air outlet of the air supply member 11 is used to guide the air enhanced by the air supply member 11, and the enhanced air is discharged through the vents on the first air supply duct 12 and the second air supply duct 13. In order to ensure timely cooling in the machine room, it is necessary to ensure that the air outlet of the air supply member 11 has a certain air supply volume, and the air outlet of the air supply member 11 needs to have a certain size. In order to ensure that the wind is not all discharged from the front vent, the size of the vent cannot be too large. In summary, the area of ​​the air outlet of the air supply member 11 is greater than or equal to 800cm 2 , the area of ​​the ventilation opening is greater than or equal to 100cm 2 And less than or equal to 700cm 2 Furthermore, the area of ​​the vent is greater than or equal to 150 cm 2 And less than or equal to 650cm 2 Furthermore, the area of ​​the vent is greater than or equal to 200 cm 2 And less than or equal to 600cm 2 .

[0029] As an implementation method, the spacing between the vents on the first air supply duct 12 and the second air supply duct 13 is greater than or equal to 0.8m. The vents are used to exhaust air on the one hand, and on the other hand, in order to make the air supply of the air-conditioning air supply device 100 uniform, a certain distance is required between the vents to prevent the air-conditioning air from being discharged from the air-conditioning exhaust port when the distance is too close.

[0030] As an embodiment, the material of the first air supply duct 12 and the second air supply duct 13 includes one or more combinations of polyurethane, rubber and plastic sponge, composite silicate or aluminum silicate. The air conditioning duct is used to guide the air, and the temperature of the air conditioning air needs to be guaranteed. The air conditioning air also generates noise. The material of the first air supply duct 12 and the second air supply duct 13 includes one or more combinations of polyurethane, rubber and plastic sponge, composite silicate or aluminum silicate, which can ensure the thermal insulation performance and sound insulation performance of the first air supply duct 12 and the second air supply duct 13.
