Description

Technical Field

[0001] The present invention relates to cooling of electronic devices, and more particularly to an environmental control system for uninterruptible power supplies and power distribution devices. Background Art

[0002] In the prior art, the storage rooms of uninterruptible power supplies and power distribution devices generally use air conditioning hoods or ducts to supply air for cooling. The indoor equipment blocks the air, resulting in uneven air supply. Usually, methods such as installing air ducts and increasing the air supply volume are used to maintain the indoor temperature. However, the temperature cannot be accurately controlled, and local air supply problems may still occur indoors, causing the operating temperature of some uninterruptible power supply equipment to rise, thereby reducing the capacity margin of the power distribution equipment and increasing the failure rate of power electronic components. In order to ensure that the indoor temperature is within the allowable range of the equipment, the only method is to reduce the air supply temperature of the air conditioner to maintain the indoor temperature.

[0003] Since the air supply system such as air ducts usually installed indoors takes up a lot of indoor space, it seriously affects the layout of indoor distribution bridges and other pipelines, further worsens the indoor air flow organization and is not easy for subsequent maintenance personnel to maintain.

[0004] Especially with the increasingly stringent requirements for data center power usage effectiveness (PUE), improving the cooling efficiency of storage rooms for uninterruptible power supplies and power distribution devices has become a key part of improving the overall power usage efficiency of data centers. Utility Model Content

[0005] In response to the shortcomings of the existing technology, this new model proposes an environmental control system for uninterruptible power supplies and distribution devices, which can solve the problems of low environmental cooling efficiency, unbalanced airflow organization, mixing of cold and hot air flows, and high air inlet temperature of local equipment in the existing technology. It can effectively increase the air supply temperature of air-conditioning equipment and thus improve the cooling efficiency of the system.

[0006] To achieve the above objectives, the present invention discloses an environmental control system for an uninterruptible power supply and a power distribution device, which includes a first chamber in which an uninterruptible power supply device and a power distribution device are placed, and further includes:

[0007] a channel isolation assembly that divides the space of the first chamber into a front channel enclosed area and a rear channel enclosed area; wherein the front of the uninterruptible power supply device and the power distribution device are located in the front channel enclosed area, and the back and top of the uninterruptible power supply device and the power distribution device are located in the rear channel enclosed area;

[0008] An airflow containment component, together with the channel isolation component, forms a sealing structure between the front channel enclosed area and the rear channel enclosed area, preventing hot air from flowing back from the rear channel enclosed area to the front channel enclosed area.

[0009] In one embodiment, the channel isolation component includes:

[0010] A thermal insulation and sealing ceiling is provided above the indoor space where the front of the uninterruptible power supply device and the power distribution device are located;

[0011] A vertical isolation assembly is flush with the front of the uninterruptible power supply device and the power distribution device, and is connected to the thermal insulation and sealed ceiling.

[0012] In one embodiment, the thermal insulation and sealing ceiling is detachable;

[0013] A detachable sealing strip is provided at the end of the vertical isolation assembly.

[0014] In one embodiment, the airflow containment assembly comprises:

[0015] a first airflow containment baffle, mounted on top of the uninterruptible power supply device and the power distribution device, and in contact with the thermally insulated and sealed ceiling;

[0016] The second airflow containment baffle is installed at the bottom of the uninterruptible power supply device and the power distribution device.

[0017] In one embodiment, an elastic member is provided at one end of the first airflow containment baffle and is connected to the uninterruptible power supply and the power distribution device.

[0018] In one embodiment, the uninterruptible power supply device is equipped with a cooling fan, the air intake direction of the cooling fan is located at the front of the device, and the hot air exhaust direction is located at the back or top of the device.

[0019] In one embodiment, a cooling fan is provided on the front of the power distribution device, and a ventilation louver with a check valve is provided on the back.

[0020] In one embodiment, the device further comprises a second chamber, wherein an air-conditioning device is placed in the second chamber;

[0021] An air inlet of the second chamber is connected to the closed area of the front channel through a first air duct formed by air supply louvers or a second air duct formed by a raised floor;

[0022] A return air port of the second chamber is communicated with the closed area of the rear channel through an air duct.

[0023] In one embodiment, the row front channel enclosed area and the row rear channel enclosed area are both provided with an air supply temperature sensor and a pressure difference sensor.

[0024] In one embodiment, a bottom-level monitoring system is further included, which is connected to the uninterruptible power supply, power distribution device, and air-conditioning equipment, and is connected to the upper-level monitoring system of the building through a network interface, so as to collect the working status of the uninterruptible power supply equipment, power distribution device and air-conditioning equipment, as well as the ambient temperature and pressure difference data in the closed area of the front channel of the row and the closed area of the rear channel of the row, so as to adjust the speed of the fan of the air-conditioning equipment to maintain a positive pressure in the closed area of the front channel of the row relative to the closed area of the rear channel of the row.

[0025] From the above scheme, it can be seen that the advantages of this new method are:

[0026] The environmental control system for an uninterruptible power supply and a power distribution device disclosed in the present invention isolates the front-row channel enclosed area from the rear-row channel enclosed area through a physical isolation component formed by an airflow containment component and the channel isolation component, so that air flows from the rear-row channel enclosed area to the rear-row channel enclosed area, preventing hot air from flowing back from the rear-row channel enclosed area to the front-row channel enclosed area.

[0054] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and illustration and are not intended to limit the present invention.

[0055] This disclosure discloses numerous specific details, such as components, elements, structures, and methods, to facilitate a thorough understanding of the embodiments of the disclosure. However, one skilled in the art will appreciate that the disclosure can still be practiced without omitting one or more specific details. In other instances, well-known details are not shown or described to avoid obscuring the scope of the disclosure.

[0056] See Figure 1-Figure 5 As shown, Figure 1 A schematic structural diagram of an environmental control system for an uninterruptible power supply and a power distribution device disclosed in one embodiment is shown; Figure 2 A schematic structural diagram of an environmental control system for an uninterruptible power supply and a power distribution device disclosed in another embodiment of the present invention is shown; Figure 3 is a schematic diagram of a power distribution device; Figure 4 is a schematic diagram of an uninterruptible power supply; Figure 5 This is a structural diagram of the first airflow containment baffle at the top.

[0057] See also Figure 1 、 Figure 2 As shown in FIG, the environmental control system 10 for an uninterruptible power supply and power distribution device comprises a first chamber 11 and a second chamber 12. The first chamber 11 houses an uninterruptible power supply 201 and a power distribution device 202, while the second chamber 12 houses an air conditioning unit 206. In one embodiment, the uninterruptible power supply 201 and the power distribution device 202 may be arranged in a single row or in a double row facing each other within the first chamber, but the present invention is not limited thereto.

[0058] The channel isolation assembly 203 divides the space of the first chamber 11 into a front-row channel enclosed area 11A and a rear-row channel enclosed area 11B. The front faces of the uninterruptible power supply 201 and the power distribution device 202 are located within the front-row channel enclosed area 11A, while the backs and tops of the uninterruptible power supply 201 and the power distribution device 202 are located within the rear-row channel enclosed area 11B. Furthermore, in this embodiment, an airflow containment assembly 204 and the channel isolation assembly 203 jointly form a sealing structure between the front-row channel enclosed area 11A and the rear-row channel enclosed area 11B, making the front-row channel enclosed area 11A a cold aisle enclosed area and the rear-row channel enclosed area 11B a hot aisle enclosed area. The sealing structure formed by the airflow containment assembly 204 and the channel isolation assembly 203 ensures the isolation of the front and rear channels of the equipment, allowing airflow from the rear-row channel enclosed area to the rear-row channel enclosed area, while preventing hot air from flowing back from the rear-row channel enclosed area 11B to the front-row channel enclosed area 11A.

[0059] Further reading Figure 1 、 Figure 2 As shown in , specifically, the channel isolation component 203 specifically includes: a thermal insulation and sealing ceiling 2031 and a vertical isolation component 2032. The thermal insulation and sealing ceiling 2031 is arranged above the indoor space where the front of the uninterruptible power supply device 201 and the power distribution device 202 are located; and the vertical isolation component 2032 is flush with the front of the uninterruptible power supply device 201 and the power distribution device 202, and is connected to the thermal insulation and sealing ceiling 2031.

[0060] In some embodiments, the thermal insulation and sealing ceiling 2031 is detachable, usually in the form of a gusset plate, which can ensure the insulation and sealing of the ceiling, and can also be dismantled and restored when the ceiling needs to be repaired.

[0061] In some embodiments, vertical insulation assembly 2032 can be constructed from gypsum board and rock wool, or can be constructed from insulated color-coated steel sandwich panels or other fire-resistant and heat-insulating wall materials. The top is connected to the insulated and sealed ceiling 2031 to ensure airtightness. In one embodiment, a removable sealing strip is provided at the end of vertical insulation assembly 2032 to further enhance the sealing effect.

[0062] Further reading Figure 1 、 Figure 2 As shown in , in one embodiment, the airflow containment assembly 204 includes: a first airflow containment baffle 2041 and a second airflow containment baffle 2042 .

[0063] The first airflow containment baffle 2041 is a movable baffle installed on the top of the uninterruptible power supply device 201 and the power distribution device 202, and in contact with the thermal insulation and sealing ceiling 2031. Figure 5 As shown in FIG, in one embodiment, a detachable elastic member 20411 is provided at one end of the first airflow containment baffle 2041 and is connected to the uninterruptible power supply 201 and the power distribution device 202, so that the uninterruptible power supply 201 or the power distribution device 202 can be easily removed when maintenance is required. In one embodiment, the elastic member can be a brush or an elastic strip.

[0064] The second airflow containment baffle 2042 is installed at the bottom of the uninterruptible power supply device 201 and the power distribution device 202. In some embodiments, further Figure 3 As shown, specifically, a heat dissipation baffle 205 is further configured at the bottom of the front of the uninterruptible power supply device 201 and the power distribution device 202, and a second airflow containment baffle 2042 is configured at the bottom of the back of the uninterruptible power supply device 201 and the power distribution device 202. The heat dissipation baffle 205 arranged on the front assists the heat dissipation of the equipment, while the second airflow containment baffle 2042 arranged on the back prevents the airflow from leaking into the closed area of the rear channel behind the equipment, forcing the airflow upward through the inside of the uninterruptible power supply device 201 and the power distribution device 202, so that the air acts on the temperature control inside the equipment.

[0065] In addition, see further Figure 3 As shown in FIG, the uninterruptible power supply device 201 has a cooling fan 2011, the air intake direction of the cooling fan is located at the front of the device, and the hot air exhaust direction is located at the back or top of the device.

[0066] In addition, see further Figure 4As shown in the figure, the power distribution device 202 is provided with a cooling fan 2021 on the front and a ventilation louver with a check valve (not shown in the figure) on the back to ensure that the inside of the power distribution device maintains a positive pressure in the closed area of the rear channel behind the equipment, and further prevents the air in the closed area 11B of the rear channel from flowing back into the inside of the power distribution device 202 and the closed area 11A of the front channel.

[0067] In addition, see further Figure 1 As shown in FIG, in one embodiment, an air conditioning device 206 is placed within the second chamber 12. This air conditioning device may be a constant temperature and humidity air conditioner, or a modular air conditioner or other air conditioning terminal. An air inlet of the second chamber 12 communicates with the pre-row channel enclosed area 11A via a first air duct formed by air supply louvers 121. The air conditioning device acts as a static pressure box to stabilize the air supply pressure, ensuring that the treated air is evenly delivered from the first air duct to the pre-row channel enclosed area 11A. Simultaneously, a return air outlet of the second chamber 12 communicates with the post-row channel enclosed area 11B via an air duct.

[0068] In addition, see Figure 2 As shown in Figure 1 Unlike the embodiment, in another embodiment, an air inlet of the second chamber 12 communicates with the enclosed area 11A of the pre-row passageway via a second air duct 122 formed by a raised floor. The underfloor space or a mezzanine serves as the second air duct. Furthermore, an air supply vent 1221 is provided in the floor. The air conditioning equipment uses the underfloor space as a static pressure chamber, ensuring that the treated air is evenly delivered from the second air duct to the enclosed area 11A of the pre-row passageway. Furthermore, in this embodiment, a return air vent of the second chamber 12 communicates with the enclosed area 11B of the post-row passageway via an air duct.

[0069] In addition, in some embodiments, air supply temperature sensors and pressure difference sensors are provided in the closed area of the front channel and the closed area of the rear channel to collect the ambient temperature and pressure difference in the closed area of the front channel and the closed area of the rear channel in real time.

[0070] In addition, some embodiments further include a bottom-level monitoring system connected to the uninterruptible power supply, power distribution device, air conditioning equipment, supply air temperature sensor, and pressure differential sensor, and connected to the building's upper-level monitoring system via a network interface. The bottom-level monitoring system monitors the operating status of the uninterruptible power supply, power distribution device, and air conditioning equipment in real time, as well as changes in ambient temperature and pressure differential within the pre-row channel enclosed area and the post-row channel enclosed area, and transmits these changes to the upper-level monitoring system. The cooling output of the air conditioner is adjusted based on the ambient temperature of the pre-row channel enclosed area to maintain the ambient temperature within the pre-row channel enclosed area. The air conditioner fan speed is adjusted based on the pressure differential data between the pre-row channel enclosed area and the post-row channel enclosed area to ensure a positive pressure within the pre-row channel enclosed area relative to the post-row channel enclosed area, further preventing airflow within the post-row channel enclosed area from backflowing into the pre-row channel enclosed area, thereby reducing air conditioning cooling efficiency.

[0071] The environmental control system for an uninterruptible power supply and power distribution device disclosed herein, on the one hand, utilizes a physical isolation assembly formed by the airflow containment assembly 204 and the channel isolation assembly 203 to isolate the front-row channel enclosed area from the rear-row channel enclosed area 11B. This allows airflow from the rear-row channel enclosed area to the rear-row channel enclosed area, preventing hot air from flowing back from the rear-row channel enclosed area 11B to the front-row channel enclosed area 11A. Secondly, by adjusting the speed of the air conditioning fan, a positive pressure is maintained within the front-row channel enclosed area relative to the rear-row channel enclosed area, further preventing airflow within the rear-row channel enclosed area from flowing back into the front-row channel enclosed area. This environmental control system for an uninterruptible power supply and power distribution device maintains the operating temperature of indoor equipment, increases the air conditioning supply temperature, reduces the air conditioning supply volume, and reduces air conditioning energy consumption in the uninterruptible power supply and power distribution device room. Furthermore, by installing an integrated bottom-level monitoring device indoors, integrated monitoring of the indoor air conditioning and electrical equipment is performed, further improving the reliability and safety of the indoor equipment without affecting its normal maintenance and use.
