Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Referring to fig. 1 to 5, an embodiment of the present invention provides an energy-saving communication cabinet, which may include a cabinet body 1, a plurality of clamping plates 2, an air suction pipe 3, and an air pump 4. Wherein:

a plurality of heat dissipation holes 101 are formed in one side of the cabinet body 1. For example, the side portion provided with the heat dissipation hole 101 may be a side portion opposite to the cabinet door of the cabinet. The plurality of clamping plates 2 are distributed in the cabinet body 1 along the vertical direction, the clamping plates 2 horizontally extend, and a constant-pressure cavity 201 with an opening facing to two sides of the cabinet body 1 is formed between each two clamping plates 2 and the cabinet body 1. In an example, the first opening of the constant pressure chamber 201 may face a side portion of the cabinet 1 opposite to the cabinet door, and the second opening of the constant pressure chamber 201 faces the cabinet door. Wherein, a plurality of splint 2 from top to bottom, can be that first splint 2 and second splint 2 form a constant voltage chamber 201, and third splint 2 and fourth splint 2 form a constant voltage chamber 201. The clamping plates 2 are connected with the side parts of the cabinet body 1, and the clamping plate 2 positioned at the top (such as the first clamping plate 2), the clamping plate 2 positioned between the two constant pressure cavities 201 (such as the second clamping plate 2 and the third clamping plate 2) and the clamping plate 2 positioned at the bottom can be fixed through the partition plates, so that the connection firmness of the clamping plates 2 in the cabinet body 1 can be improved.

The communication server 10 is accommodated in the constant voltage cavity 201, and the first opening of the constant voltage cavity 201 is communicated with the heat dissipation hole 101. The air suction pipe 3 is communicated with a second opening of the constant pressure cavity 201 to input cold source air into the constant pressure cavity 201. When the cabinet works, the cabinet body 1 is sealed through the cabinet door, cold source air is input into the cabinet body 1 through the air suction pipe 3, and enters the constant pressure cavity 201 from the second opening of the constant pressure cavity 201, so that the communication server 10 accommodated in the constant pressure cavity 201 is cooled. The cold source air is air which has a low temperature and can cool the communication server 10. The cold source air after heat exchange flows out of the constant pressure cavity 201 through the first opening of the constant pressure cavity 201, and the cold source air after heat exchange is guided out of the cabinet body 1 through the heat dissipation holes 101. The air pump 4 is in air path communication with the air suction pipe 3 to adjust the pressure in the constant pressure cavity 201. The air pump 4 can adjust the air quantity of cold source air entering the cabinet body 1, so that the air pump 4 of each cabinet can be adjusted according to the running power of the communication server 10 in each cabinet in a communication machine room comprising a plurality of cabinets. Therefore, the utilization rate of cold source air can be improved, more accurate temperature control can be realized, and the effect of saving energy is achieved.

In an alternative embodiment of the invention, as shown in fig. 1, 3 and 4, the cabinet may further include a telescopic unit 5 and a baffle 6. In an embodiment, the telescopic unit 5 may be an electric telescopic rod, an electric cylinder, or the like. The telescopic unit 5 is fixed in the outside of the cabinet body 1, the baffle 6 with the telescopic shaft of the telescopic unit 5 is fixed, the baffle 6 runs through the cabinet body 1, and with 1 sliding connection of the cabinet body, wherein, the baffle 6 is located the second opening part of the constant pressure chamber 201, and with the cooperation of the communication server 10 is right the second opening of the constant pressure chamber 201 seals, drive when the telescopic unit 5 is flexible the baffle 6 slides to through adjusting the amount of wind of second open-ended opening area accuse refrigeration source wind. In one embodiment, the clamping plate 2 is further provided with a sliding groove, and the baffle 6 is embedded in the sliding groove.

Referring to fig. 3, the cross-sectional shape of the baffle 6 may be L-shaped or U-shaped. The telescopic unit 5 is located between the baffle 6 and the cabinet 1, so that the communication server 10 and the baffle 6 form a complete seal for the second opening of the constant pressure cavity 201 when the telescopic unit 5 is in a fully telescopic state. For example, the shutter 6 in this state abuts against the side portion of the communication server 10, thereby completely closing the second opening of the constant-pressure chamber 201. In an embodiment, the communication server 10 may be accommodated in the middle of the second opening of the constant voltage cavity 201, the number of the baffles 6 located at the second opening of each constant voltage cavity 201 may be 2, and the 2 baffles 6 are symmetrically arranged about the middle of the second opening of the constant voltage cavity 201. Under the condition that the second opening is completely closed, cold source air in the cabinet body 1 cannot complete air cooling circulation, and the communication server 10 cannot perform cooling and heat dissipation.

Referring to fig. 4, under the condition that the telescopic unit 5 is in the extended state, the telescopic unit 5 drives the baffle 6 to do the linear motion away from the communication server 10, that is, drives the baffle 6 to move toward the outside of the cabinet 1, so that the opening area of the second opening of the constant-pressure cavity 201 is enlarged, the air volume of the cold source air entering the constant-pressure cavity 201 through the second opening in unit time is enlarged, and the heat dissipation efficiency of the communication server 10 can be improved.

In an alternative embodiment of the invention, referring to fig. 2, the cabinet may further include a solenoid valve 7, and the solenoid valve 7 is in air path communication with the air suction pipe 3 to control on/off of the air suction pipe 3. When detecting that the operation power of the communication server 10 in the corresponding cabinet is low or in the standby mode, the electromagnetic valve 7 may be operated to close the air path of the air suction pipe 3. Thereby reducing unnecessary cold source consumption and achieving the purpose of saving energy.

In an optional embodiment of the invention, the cabinet may further include a temperature sensing element 8, a temperature measuring circuit, and a control module, where the temperature sensing element 8 is located in the constant voltage cavity 201, and the temperature sensing element 8 is a temperature sensor or a thermistor. The temperature measuring circuit is coupled with the temperature sensing element 8, the control module is coupled with the temperature measuring circuit and coupled with the air pump 4, and the control module controls the air pump 4 to act according to the temperature sensing signal collected by the temperature sensing element 8. For example, the temperature sensing element 8 is configured to detect the temperature of the communication server 10, the temperature sensing circuit converts the temperature sensing signal collected by the temperature sensing element 8 into an electrical signal corresponding to the temperature sensing signal, and the electrical signal is input to the control module, and the control module may determine the temperature of the communication server 10 according to the electrical signal, and thereby control the operation of the air pump 4. In another embodiment, the control module may be further coupled to the solenoid valve 7 and the telescopic unit 5, respectively, so that the solenoid valve 7 and the telescopic unit 5 may be controlled by the control module to operate.

For example, when it is detected that the temperature (which may be an average value of the temperatures of the plurality of communication servers 10) in a certain cabinet is a first temperature value, the power of the air pump 4 is adjusted to a first power value, so that the pressure in the constant pressure chamber 201 is a first pressure value. Wherein the first temperature value, the first power value and the first pressure value may be preset. For another example, when the temperature in a certain cabinet is detected to be greater than the first temperature value, the power of the air pump 4 may be increased, for example, the power of the air pump 4 may be increased in proportion to the first power value. For example, the power of the air pump 4 after being increased may be 1.2 times, 1.5 times, 1.8 times, 2 times, etc. of the first power value, and is not limited herein. For another example, when the temperature in a certain cabinet is detected to be lower than the first temperature value, the power of the air pump 4 may be reduced, for example, the power of the air pump 4 may be reduced proportionally to the first power value. For example, the power of the air pump 4 after the reduction can be 0.8 times, 0.5 times, 0.3 times, etc. of the first power value, and is not limited herein.

Referring to fig. 5, in an embodiment, when the temperature sensing element 8 is a thermistor, it can be embedded in the splint 2, and the temperature sensing element 8 can be located above the communication server 10 and can be attached to the CPU of the communication server 10, so as to improve the accuracy of temperature detection.

In the operation process of the machine room, the communication servers 10 in the same cabinet have different functions, so that the different communication servers 10 in the same cabinet have different demands for cold source air, and the temperatures of the different communication servers 10 can be determined by the temperature sensing elements 8 arranged in each constant-pressure cavity 201. So that the opening area of the second opening of the corresponding constant-pressure chamber 201 can be adjusted according to the temperature of each communication server 10. For example, when the temperature of the corresponding communication server 10 is greater than or equal to the second temperature value, the expansion unit 5 may drive the baffle 6 to extend outward for a certain length, so as to increase the amount of cold source air passing through the constant pressure cavity 201, and improve the heat dissipation efficiency of the communication server 10. For another example, when the temperature of the corresponding communication server 10 is lower than the second temperature value, the retractable unit 5 may drive the baffle 6 to retract inward, so that the volume of the cold source air passing through the constant pressure cavity 201 is reduced. Therefore, more cold source air can be provided for the communication server 10 with higher temperature in the same cabinet in a targeted manner, the utilization rate of the cold source air is improved, and fine control of the cold source air is facilitated.

In addition, the access frequency of the communication server 10 in the same cabinet can be monitored through the control module. Wherein, the access frequency of the communication server 10 and the temperature of the communication server 10 have a direct proportion relation. When the access frequency of a communication server 10 is higher, more cold source wind can be provided to the corresponding communication server 10. For example, by controlling the air volume and speed of the cold source air, the requirement of the cold source air of each communication server 10 is precisely controlled, and the utilization rate of the cold source air is improved.

In an optional embodiment of the invention, the cabinet further includes a protective cover 9 fixed outside the cabinet body 1, and the protective cover 9 wraps the telescopic unit 5 and the baffle 6 located outside the cabinet body 1. The protective cover 9 can protect the telescopic unit 5 and the baffle 6, so that the service life of the telescopic unit 5 and the baffle 6 can be prolonged. And the product performance of the cabinet is further optimized.
