As shown in fig. 1, fig. 1 is a schematic structural diagram of an outdoor communication cabinet according to an embodiment of the present application. The outdoor communication cabinet 100 comprises a cabinet 1, wherein the cabinet 1 is provided with a mounting cavity 10, and further, an air inlet 11 and an air outlet 12 are formed in the cabinet 1. The air inlet 11 and the air outlet 12 are communicated with the installation cavity 10. The air inlet 11 can enable external cold air to enter the installation cavity 10 of the cabinet 1, and further cool communication equipment arranged in the installation cavity 10. And the air outlet 12 can ensure that the hot air in the installation cavity 10 can be discharged to the outside.

With continued reference to fig. 1, the outdoor communication cabinet 100 provided herein further includes a heat exchange conduit 2, at least a portion of the heat exchange conduit 2 being buried under the ground. The heat exchange pipeline 2 is provided with an air outlet end 22 and an air inlet end 21, the air outlet end 22 is communicated with the air inlet end 21, and the air inlet end 21 and the air outlet end 22 are arranged on the ground surface. Wherein the air outlet end 22 is communicated with the air inlet 11 of the cabinet 1.

Thus, air near the surface of the earth can enter the interior of the heat exchange tube 2 from the air inlet end 21 of the heat exchange tube 2 and flow along the heat exchange tube. When surface air flows from the inlet end 21 to the heat exchange tube to the portion 2 buried in the ground, it is easily understood that the ground temperature is far lower than the surface temperature. Therefore, when the surface air flows through the part of the heat exchange pipeline 2 buried underground, the surface air is cooled by the natural cold source underground, and then the air with lower temperature (cold air for short) is obtained. This portion of the cool air will continue to flow along the heat exchange tubes 2 and out the outlet end 22. Further, the cold air enters the installation cavity 10 of the cabinet 1 through the air inlet 11 of the cabinet 1, and then the communication equipment in the installation cavity 10 is cooled.

In addition, in order to enable the surface air entering the heat exchange pipe 2 to exchange heat with the natural cold source in the ground sufficiently, it is necessary to lengthen the residence time of the surface air in the heat exchange pipe 2 as much as possible. To achieve this, in some embodiments of the present application, as shown in fig. 2, the heat exchange tube 2 is spirally buried in the ground to extend the flow path of the surface air in the heat exchange tube 2 after entering the heat exchange tube 2, thereby extending the residence time of the surface air in the ground.

As can be seen from the above description, the outdoor communication cabinet 100 provided by the present application can utilize the underground natural cold source to prepare cold air, and convey the cold air into the installation cavity 10 of the cabinet 1 to cool the communication equipment. In this way, the work load of the air conditioner (the air conditioner is not shown in the figure) can be reduced to some extent, and the work time of the air conditioner can be reduced. And further solves the problems of high electricity consumption and short service life of the air conditioner.

As shown in fig. 1, the outdoor communication cabinet 100 provided herein further includes a filter assembly disposed outside the installation cavity 10. The filtering component can filter cold air flowing out of the air outlet end 22 of the heat exchange pipeline 2, and further impurities such as dust are prevented from entering the installation cavity 10 of the cabinet 1 along with the cold air, so that the cleaning of the working environment of communication equipment in the installation cavity 10 is ensured, the impurities such as dust cannot be invaded in communication, and the service life of the communication equipment is prolonged.

Next, the structure of the above filter assembly is further described, and as shown in fig. 1, the filter assembly includes a bellows 31, and a first filter screen 32 disposed in the bellows 31. The bellows 31 is arranged outside the installation cavity 10, one side of the bellows 31 is communicated with the air inlet 11 of the cabinet 1, and the other side of the bellows 31 is communicated with the air outlet end 22 of the heat exchange pipeline 2.

Based on this, the first filter screen 32 disposed in the bellows 31 is also disposed adjacent to the air intake 11 of the cabinet 1. To ensure that the cool air exiting the air outlet end 22 can be filtered before entering the installation cavity 10 to remove dust or other debris entrained in the cool air and thereby ensure the safety of the communication equipment disposed within the installation cavity 10.

In some embodiments of the present application, as shown in fig. 1, the outdoor communication cabinet 100 provided in the present application further includes a second filter screen 320, where the second filter screen 320 is disposed at the air inlet end 21 of the heat exchange tube 2. The second filter screen 320 is used for preventing sundries from falling into the heat exchange pipeline 2 and preventing small animals from entering the heat exchange pipeline 2, so that the heat exchange pipeline 2 is prevented from being blocked, and cold air can be prepared by using a natural cold source.

In some embodiments, the filter assembly further comprises a first fan 33, the first fan 33 being disposed inside the bellows 31, and the first fan 33 being disposed adjacent to the air intake 11 of the cabinet 1.

Thus, when the first fan 33 works, air in the bellows 31 can be discharged into the installation cavity 10 through the air inlet 11, and the bellows 31 is in a negative pressure state. In this case, the cold air in the heat exchange pipeline 2 can enter the bellows 31 from the air outlet end 22 more quickly, and enter the installation cavity 10 through the air inlet 11 under the action of the first fan 33, so that the temperature of the communication equipment in the installation cavity 10 is reduced.

In the process of cooling the communication equipment in the cabinet 1 by using the natural cold source, air outside the cabinet 1 continuously enters the cabinet 1. In this process, the moisture in the external air also enters the cabinet 1 along with the cold air, which causes the humidity of the air in the cabinet 1 to rise, and affects the normal operation of the communication equipment in the cabinet 1.

In order to solve the problem of high air humidity in the cabinet 1, as shown in fig. 1, the outdoor communication cabinet 100 provided in the application further includes a dehumidifying assembly 4, where the dehumidifying assembly 4 is disposed in the installation cavity 10 and is used for reducing the humidity of the air in the installation cavity 10. The dehumidification assembly 4 includes a heat exchanger 41 and a communication tube 42. Wherein the heat exchanger 41 is located within the mounting cavity 10. As further shown in fig. 3, the heat exchanger 41 has a hot air duct 411 and a cold air duct 412, and the hot air duct 411 and the cold air duct 412 are disposed at intervals. And one end of the cold air duct 412 is communicated with the air inlet 11, and the other end is communicated with the installation cavity 10.

In some embodiments, the hot air duct 411 extends along a first direction X, the cold air duct 412 extends along a second direction Y, and the first direction X and the second direction Y are perpendicular (see fig. 1). In this way, the arrangement of the dehumidifying component 4, the filtering component and the communication pipeline can be facilitated.

Further, the communicating pipe 42 is located in the installation cavity 10, and one end of the communicating pipe 42 is communicated with the hot air duct 411, and the other end is disposed near the top of the cabinet 1.

In this case, the cold air produced by the underground natural cold source enters the cold air duct 412 of the heat exchanger 41 through the air inlet 11, and then flows into the installation cavity 10, and the hot air at the top of the cabinet 1 enters the hot air duct 411 through the communicating pipe 42. Since the hot air duct 411 and the cold air duct 412 are disposed at a distance, the hot air and the cold air flowing in the hot air duct 411 and the cold air duct 412 exchange heat. During the heat exchange process, the hot air flowing in the hot air duct 411 is cooled by the cold air in the cold air duct 412, so that the water vapor in the hot air is condensed into condensed water, and the humidity of the air in the cabinet 1 can be reduced.

In some embodiments of the present application, as shown in fig. 3, the above-mentioned dehumidification assembly 4 further includes a second fan 43, where the second fan 43 is disposed in the communicating pipe 42 and is disposed at one end of the communicating pipe 42 near the top of the cabinet 1, so that when the second fan 43 works, air at the top of the cabinet 1 can be sucked into the communicating pipe 42 and then into the hot air duct 411 of the heat exchanger 41. The second fan can enable hot air at the top of the cabinet 1 to enter the heat exchanger 41 more efficiently to exchange heat with cold air, so that water vapor in air in the cabinet 1 is condensed into condensed water more rapidly and is discharged out of the cabinet 1, and the purpose of reducing the air humidity in the cabinet 1 is achieved.

On this basis, in some embodiments of the present application, as shown in fig. 3, the above-mentioned dehumidification assembly 4 further includes a water receiving tray 44 and a drain pipe 45. The water pan 44 is disposed at a side of the heat exchanger 41 away from the communicating tube 42, that is, the water pan 44 is disposed below the heat exchanger 41 to receive condensed water dropping from the hot air duct 411. Based on this, one end of the drain pipe 45 communicates with the water receiving tray 44, and the other end extends out of the cabinet 1 to drain the condensed water, thereby avoiding damage to the communication device caused by overflow of the condensed water from the water receiving tray 44.

In addition, in order to enable the cool air flowing out of the cool air duct 412 of the heat exchanger 41 to cool the communication equipment in the installation cavity 10 better, as shown in fig. 1, the outdoor communication cabinet 100 provided in the application further includes an air deflector 46, the air deflector 46 is disposed in the installation cavity 10 and connected with the heat exchanger 41, and the air deflector 46 is disposed at the other end of the cool air duct 412, that is, the air deflector 46 is disposed at the end of the cool air duct 412 away from the air inlet 11 of the cabinet 1. The direction of extension of the deflector 46 is directed towards the top of the cabinet 1.

In this way, when the cool air flows out from the cool air duct 412 of the heat exchanger 41, the cool air flows in the direction toward the top of the cabinet 1 under the guiding action of the air deflector 46, and the density of the cool air is greater than that of the air with higher temperature. Thus, the cool air will flow downwards from the top of the cabinet 1, thereby enabling better cooling of the communication equipment within the cabinet 1.

In addition, there is a tendency for precipitation to increase in summer, and in order to prevent damage to communication equipment caused by rainwater flowing backward into the interior of the cabinet 1 through the drain pipe 45. In some embodiments, the drain 45 may also include a one-way valve disposed within the drain 45. The one-way valve ensures that the condensate in the drip tray 44 is drained through the drain 45, while preventing water outside the cabinet from entering the interior of the cabinet 1 through the drain 45.

On the basis, in other embodiments of the present application, as shown in fig. 1, the outdoor communication cabinet 100 provided in the present application further includes a water baffle 5, where the water baffle 5 is disposed adjacent to the air outlet 12 of the cabinet 1 and is connected to the cabinet 1. Furthermore, it should be noted that the projection of the air outlet 12 onto the water baffle 5 is located within the outline of the water baffle 5, so as to ensure that the water baffle 5 can completely block the air outlet 12.

In addition, it should be noted that a space is provided between the water baffle 5 and the air outlet 12 of the cabinet 1, so as to ensure that the air in the cabinet 1 can be exhausted through the air outlet 12.

In this way, the water baffle 5 can prevent rainwater from entering the cabinet 1, and ensure that the communication equipment installed in the installation cavity 10 works normally. Meanwhile, as the space is reserved between the water baffle 5 and the air outlet 12, the water baffle 5 can not influence the air discharge in the cabinet 1.

In some embodiments of the present application, as shown in fig. 1, the outdoor communication cabinet 100 provided in the present application further includes a controller 6, where the controller 6 is disposed in the bellows 31 and connected with the bellows 31. Further, the first fan 33 and the second fan 43 are each electrically connected to the controller 6. Further, the outdoor communication cabinet 100 further includes a temperature sensor 7, the temperature sensor 7 is disposed in the heat exchange tube 2, and is disposed adjacent to the air outlet end 22 of the heat exchange tube 2, and the temperature sensor 7 is further electrically connected to the controller 6.

The temperature sensor 7 is used for detecting the temperature of cold air discharged from the air outlet end 22 of the heat exchange pipeline 2, when the temperature is lower than a temperature preset value, the temperature sensor 7 sends an electric signal to the controller 6 to enable the controller 6 to control the second fan 43 to blow air in the air box 31 into the cabinet 1, so that the cold air at the air outlet end 22 can enter the air box 31, then enters the cabinet 1 through the air inlet 11 on the cabinet 1 and cools communication equipment in the cabinet 1.

When the temperature of the cool air discharged from the air outlet end 22 is higher than the preset temperature value, the temperature sensor 7 does not want the controller 6 to send an electrical signal, and the controller 6 does not control the second fan 43 to work. In this way, air with unqualified temperature can be prevented from entering the cabinet 1, and the communication equipment is cooled only by the air conditioner arranged in the cabinet 1. On the one hand, the second fan 43 does not work, so that electric energy can be saved to a certain extent, and on the other hand, air with temperature not reaching the standard can be prevented from entering the cabinet 1, and then the load of the air conditioner is prevented from increasing.

In other embodiments of the present application, as shown in fig. 1, the outdoor communication cabinet 100 provided herein further includes a humidity sensor 8. The humidity sensor 8 is disposed within the mounting cavity 10 of the cabinet 1, and the humidity sensor 8 is disposed adjacent the top of the cabinet 1 and is electrically connected to the controller 6.

Based on this, the humidity of the air at the top of the cabinet 1 can be detected by the above-described humidity sensor 8. When the humidity sensor 8 detects that the humidity of the air at the top of the cabinet 1 is greater than the humidity preset value, the humidity sensor 8 sends an electrical signal to the controller 6, and the controller 6 further controls the first fan 33 to operate, so that the air at the top of the cabinet 1 enters the communicating pipe 42 and enters the hot air duct 411 of the heat exchanger 41 along the communicating pipe 42. And exchanges heat with the cold air in the cold air duct 412, and during the heat exchange process, the water vapor in the air in the hot air duct 411 condenses into condensed water and drops into the water pan 44.

When the humidity of the air at the top of the cabinet 1 does not exceed the preset humidity value, the humidity sensor 8 does not send an electrical signal to the controller 6, and the first fan 33 is not operated.

In this way, on the one hand, when the humidity of the air at the top of the cabinet 1 does not exceed the preset humidity value, the controller 6 does not control the first fan 33 to work, so that the effects of saving electric energy and prolonging the service life of the first fan 33 can be achieved. On the other hand, when the air in the cabinet 1 is dehumidified, the temperature of the cold air in the cold air duct 412 will be raised to a certain extent by the cold air heat exchange in the heat exchanger 41, and the cooling effect on the communication equipment will be affected when the dehumidification is performed. Therefore, the first fan 33 is not controlled to operate when dehumidification is not required, and a good cooling effect can be ensured.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
