Fig. 2 is a schematic perspective view of an integrated energy-saving cabinet according to a first embodiment of the invention. As shown in fig. 2, the integrated energy-saving cabinet 2 shown in fig. 2 is substantially the same as the integrated cabinet 1 shown in fig. 1, that is, the integrated energy-saving cabinet 2 is also a rectangular frame structure, and includes a cabinet body 21, a cabinet door 22 mounted on the cabinet body 21 and capable of being opened and closed relative to the cabinet body 21, wherein the cabinet body 21 includes a bottom plate 211 and a top plate 212 which are oppositely arranged, a side plate 213 and a side plate 214 which are oppositely arranged, a back plate 215 which is oppositely arranged relative to the cabinet door 22, and an air conditioner 23 located on the bottom plate 211 of the cabinet body 21, wherein an air outlet 231 of the air conditioner 23 is close to the cabinet door 22, and a flow direction of blown cold air is directed from the air outlet 231 to the top plate 212 and parallel to the cabinet door 22, and a plurality of modular electronic devices 24 such as an uninterruptible power supply.
The integrated energy-saving cabinet 2 further includes an air intake device 25, an air exhaust device 26, a temperature sensor 271, a humidity sensor 272, and a monitoring device (described below with reference to fig. 3) located inside the cabinet body 21. Wherein the air intake device 25 is embedded on the cabinet door 22 and close to the bottom plate 211, the air intake device 25 allows air outside the cabinet 21 to enter the inside of the cabinet 21, and simultaneously prevents air inside the cabinet 21 from circulating to the outside. The air exhausting device 26 is embedded in the top plate 212 and is close to the back plate 215, and the air exhausting device 26 is used for exhausting air inside the cabinet 21 when in operation. A temperature sensor 271 and a humidity sensor 272 are fixed on the cabinet 21, and are respectively used for measuring a temperature value and a relative humidity value outside the cabinet 21. The monitoring device is used for controlling the working state of the air exhaust device 26 and the air conditioner 23.
Fig. 3 is a block diagram of a monitoring device in the integrated energy saving cabinet shown in fig. 2. As shown in fig. 3, the monitoring device 29 includes a first analog-to-digital converter 291, a second analog-to-digital converter 292, a first numerical comparator 293, a second numerical comparator 294, and a control unit 295.
The temperature sensor 271 measures a temperature value outside the cabinet 21 and outputs a temperature signal Vt corresponding to the measured temperature value to the first analog-to-digital converter 291, and the first analog-to-digital converter 291 converts the temperature signal Vt into a corresponding temperature digital signal Dt. The first numerical comparator 293 receives the temperature digital signal Dt and compares it with a first threshold temperature T1 and a second threshold temperature T2, thereby outputting a first comparison signal C11, wherein the first threshold temperature T1 to the second threshold temperature T2 are the allowable operating temperature range or the safe operating temperature range of the integrated energy-saving cabinet 2, and the second threshold temperature T2 is greater than the first threshold temperature T1.

Fig. 4 is a control flow chart of the monitoring device shown in fig. 3. As shown in fig. 4, in step S1, the monitoring device 29 obtains the temperature value T and the relative humidity value RH outside the cabinet 21, which are respectively measured by the temperature sensor 271 and the humidity sensor 272. Step S2, the measured RH value RH is compared with the predetermined RH value Href, and the measured temperature value T is compared with the first threshold temperature T1 and the second threshold temperature T2. When the first threshold temperature T1 < the measured temperature value T ≦ the second threshold temperature T2 and the measured relative humidity value RH ≦ the predetermined relative humidity value Href, the following step S31 is performed: controlling the air exhaust device 26 to work and controlling the air conditioner 23 to stop working; when the measured temperature value T > the second threshold temperature T2, or the measured relative humidity value RH > the predetermined relative humidity value Href, the following step S32 is performed: the exhaust device 26 is controlled to stop working, and the air conditioner 23 is controlled to refrigerate to blow out cold air; when the measured temperature value T is less than or equal to the first threshold temperature T1, the following step S33 is executed: the operation of the air exhausting device 26 is controlled to be stopped, and the operation of the heating device built in the air conditioner 23 is controlled to blow out the hot air, that is, the heating of the air conditioner 23 is controlled.
The function of the monitoring device 29 is explained below by way of example. Assuming that the first threshold temperature T1 is 15 degrees celsius, the second threshold temperature T2 is 27 degrees celsius, and the predetermined relative humidity value Href is 80%.
(1) It is assumed that the temperature value T measured by the temperature sensor 271 is 20 degrees celsius, i.e., between 15 degrees celsius and 27 degrees celsius, and the relative humidity value RH measured by the humidity sensor 272 is 50%, i.e., not more than 80%. The first analog-to-digital converter 291 outputs a temperature digital signal Dt corresponding to the measured temperature value T, and the first numerical comparator 293 outputs a first comparison signal C11 of a first level (e.g., a high level). The second analog-to-digital converter 292 outputs a humidity digital signal Dh corresponding to the measured relative humidity value RH, and the second numerical comparator 294 outputs a second comparison signal C12 of a first level (e.g., a high level). The control unit 295 outputs a first control signal CS to control the operation of the air exhausting device 26 and to control the operation of the air conditioner 23.
The air flow formed inside the cabinet 21 is as follows: first, the air exhausting device 26 exhausts the air inside the cabinet 21 to form a negative pressure inside the cabinet 21, the air outside the cabinet 21 passes through the air intake device 25 and enters the inside of the cabinet 21, and then moves in a direction from the bottom plate 211 to the top plate 212 in the closed cold channel, and flows through the surface of the stacked panels of the electronic device 24, the air is sucked by a suction fan (not shown in the drawing) installed on the panel of the electronic device 24, the air flows from the panel of the electronic device 24 to the direction of the back plate 215, and becomes hot air after exchanging heat with the electronic device 24 and blows towards the back plate 215, and the air exhausting device 26 exhausts the hot air inside the cabinet 21 and exhausts the hot air outside the cabinet 21.
(2) The relative humidity value RH measured by the humidity sensor 272 is assumed to be 90%, i.e. greater than 80%. The second analog-to-digital converter 292 outputs a humidity digital signal Dh corresponding to the measured relative humidity value RH, and the second numerical comparator 294 outputs a second comparison signal C12 of a second level (e.g., a low level). The control unit 295 outputs a second control signal CS to control the exhaust device 26 not to operate and the air conditioner 23 to cool.
The air flow formed inside the cabinet 21 is as follows: the air conditioner 23 blows out cold air from the air outlet 231, the cold air flows in the direction from the air outlet 231 to the top plate 212 in the closed cold channel and sequentially flows through the stacked panels of the electronic equipment 24, the air suction fan mounted on the panels of the electronic equipment 24 sucks in the cold air, the cold air flows from the panels of the electronic equipment 24 to the direction of the back plate 215, the cold air is changed into hot air after being subjected to heat exchange with the electronic equipment 24 and blows towards the back plate 215, and finally flows towards the air inlet of the air conditioner 23, and the compressor of the air conditioner 23 cools and blows out the cold air from the air outlet 231.
(3) It is assumed that the temperature value T measured by the temperature sensor 271 is 40 degrees celsius, i.e., greater than 27 degrees celsius. The first analog-to-digital converter 291 outputs a temperature digital signal Dt corresponding to the measured temperature value T, and the first numerical comparator 293 outputs a first comparison signal C11 of a second level (e.g., a low level). The control unit 295 outputs a second control signal CS to control the exhaust device 26 not to operate and the air conditioner 23 to cool.
The flow direction of the air formed inside the cabinet 21 is the same as that in the case (2) above, and will not be described again.
(4) It is assumed that the temperature value T measured by the temperature sensor 271 is 10 degrees celsius, i.e., not more than 15 degrees celsius. The first analog-to-digital converter 291 outputs a temperature digital signal Dt corresponding to the measured temperature value T, and the first numerical comparator 293 outputs a first comparison signal C11 of a second level (e.g., a low level). The control unit 295 outputs a third control signal CS to control the exhaust device 26 not to operate and to control the heating device built in the air conditioner 23 to operate.
The air flow formed inside the cabinet 21 is as follows: the hot air is blown out from the air outlet 231 of the air conditioner 23, the hot air flows in the direction from the air outlet 231 to the top plate 212 in the closed cold channel and sequentially flows through the stacked panels of the electronic equipment 24, the hot air is sucked in by the suction fan installed on the panel of the electronic equipment 24, the hot air flows from the panel of the electronic equipment 24 to the direction of the back plate 215, the hot air is changed into cold air after heat exchange with the electronic equipment 24, the cold air is blown to the back plate 215 and finally flows to the air inlet of the air conditioner 23, and the cold air is heated by the built-in heating device of the air conditioner 23 and is blown out from the air outlet 231 thereof.
An air inlet device 25 and an air exhaust device 26 are installed on a cabinet body 21 of the invention, a monitoring device 29 acquires a temperature value and a relative humidity value outside the cabinet body 21, when the temperature value and the relative humidity value are respectively in a preset temperature range and a preset relative humidity range, the monitoring device 29 controls the air exhaust device 26 to work and controls an air conditioner 23 to not work, and the air exhaust device 26 sucks air outside the cabinet body 21 into the cabinet body 21 and flows in the cabinet body 21, thereby radiating heat of electronic equipment 24. Because the power consumption of the air exhaust device 26 is far lower than that of the air conditioner 23, energy conservation and emission reduction can be realized, and the heat dissipation cost is reduced.
The temperature sensor 271 and the humidity sensor 272 are arranged on the outer side wall of the cabinet body 21 and used for measuring the temperature value and the relative humidity value outside the cabinet body 21, on one hand, the ambient temperature value and the relative humidity value where the cabinet body 21 is located are accurately measured, and when the ambient temperature value and the relative humidity value meet the heat dissipation requirement of the electronic equipment 24, the air exhaust device 26 is controlled to work so as to fully utilize the air of the environment where the cabinet body 21 is located to dissipate heat, so that the cooling efficiency is further improved, and the heat dissipation cost is reduced. On the other hand, since the air conditioner 23 has a lower temperature at the air outlet 231 and a higher temperature near the back panel 15 during cooling, the temperature inside the cabinet 21 is not uniformly distributed, and the temperature sensor 271 and the humidity sensor 272 are disposed outside the cabinet 21, so as to avoid the monitoring device 29 from erroneously controlling the air exhausting device 26 and the air conditioner 23.
The air conditioner 23 is installed on the bottom plate of the cabinet body, and the air conditioner 23 is convenient to install and fix. The flow direction of the cool air blown out from the air outlet 231 of the air conditioner 23 is parallel to the cabinet door 22 and directed from the air outlet 231 toward the ceiling plate 212, so that the cool air can be blown onto all the panels of the electronic equipment 24.
The air intake means 25 is embedded in the cabinet door 22 near the bottom plate 211, and air entering from the air intake means will flow through all the panels of the electronic device 24. The proximity of the air exhaust 26 to the back panel 215 facilitates the discharge of cool air through the air exhaust 26 after sufficient heat exchange with the electronic device 24. After the cold air exchanges heat with the electronic equipment 24 to become hot air, the hot air naturally moves upward, and at this time, the air exhausting device 26 is mounted on the top plate 212, the hot air moves toward the air exhausting device 26, and the hot air can be completely exhausted from the cabinet 21 by using the air exhausting device 26 with small power.
Fig. 5 is a perspective view of an integrated energy-saving cabinet according to a second embodiment of the invention. The integrated energy saving cabinet 3 shown in fig. 5 is substantially the same as the integrated energy saving cabinet 2 shown in fig. 2, except that the integrated energy saving cabinet 3 further includes a mixing box 381 fixed on the cabinet body 31 and a heat discharging pipe 382 communicated with the mixing box. The mixing box 381 is fixed on the top plate 312 and covers the air exhausting device 36, and its air inlet is coupled with the air outlet of the air exhausting device 36. In which the mixing box 381 shown in fig. 5 is a transparent rectangular parallelepiped, the shape of the mixing box 381 and its material are not intended to be limited in the present invention, but only to clearly show the exhaust device 36 covered by the mixing box 381 and its relative position.
When the exhaust device 36 is operated, the hot air exhausted from the exhaust device 36 is blown out from the top plate 312, and the mixing tank 381 is used for collecting the hot air exhausted from the exhaust device 36 and guiding the hot air to a desired place, for example, a place far away from the cabinet 31 through the heat exhaust pipe 382, so as to prevent the temperature in the vicinity of the cabinet 31 from rising.
In other embodiments of the present invention, when the integrated energy saving cabinet does not have a requirement for the relative humidity of the application environment, the integrated energy saving cabinet of the present invention may also not have a humidity sensor, and accordingly, the monitoring device does not have the second analog-to-digital converter 292 and the second digital comparator 294, or the second comparing device, and then the monitoring device outputs a control signal to control the working states of the air exhausting device and the air conditioner according to the temperature value measured by the temperature sensor.
The invention is not intended to be limited to the exhaust device being mounted on the top panel of the cabinet, and in another embodiment of the invention, the exhaust device may also be mounted on the side panels or the back panel of the cabinet. Also, the present invention is not limited to the air conditioner being mounted on the bottom plate, and in another embodiment, the air conditioner may be mounted near the top plate, and the direction of the cool air blown out of the outlet is directed from the outlet thereof toward the bottom plate.
The cabinet door can be made of metal materials, can also be made of transparent materials such as glass, and the transparent cabinet door is convenient for observing the running state of the modularized electronic equipment such as a server, power distribution and an uninterrupted power supply in the cabinet body.
Although the present invention has been described by way of preferred embodiments, the present invention is not limited to the embodiments described herein, and various changes and modifications may be made without departing from the scope of the present invention.
