The first embodiment is as follows:
the embodiment provides an outdoor cabinet for 5G mobile communication, which comprises a casing 200, a fan assembly 300, a driving assembly 100 and a filter screen 410:
the casing 200 is a substantially rectangular casing, the casing 200 has a first window and a second window respectively formed on an upper surface and a lower surface, and the casing 200 is a relatively sealed casing and can exchange air with the outside only through the first window and the second window. The inside of the cabinet 200 is used to house 5G communication equipment, and the 5G communication equipment generates a large amount of heat during operation, and since the cabinet 200 is relatively sealed, the heat is accumulated inside the cabinet 200 to raise the temperature inside the cabinet 200.
The fan assembly 300 includes a first fan 320 at a first window and a second fan 400 at a second window. The blades on the first fan 320 are deflectable and have respective first and second states before and after deflection; the blades on the second fan 400 are deflectable and have respective third and fourth states before and after deflection.
In the first state, the blades of the first fan 320 are in a horizontal state (the first direction is a vertical direction), and at this time, the first fan 320 completely blocks the first window, and no matter whether the first fan 320 rotates, the air in the enclosure 200 cannot be exhausted from the first window.
In the second state, the blades of the first fan 320 are in the inclined state, and at this time, the first fan 320 rotates to drive the air in the casing 200 to be discharged outwards.
In the third state, the blades of the second fan 400 are in the inclined state, and the second fan 400 rotates to drive the external air into the interior of the casing 200.
In the fourth state, the blades of the second fan 400 are in a vertical state, and if the second fan 400 does not rotate, the second fan 400 does not affect the exchange of air between the cabinet 200 and the outside at all; if the second fan 400 rotates, the second fan 400 obstructs the exchange of air between the cabinet 200 and the outside to some extent, but the influence is limited, and for example, when there is a large pressure difference between the inside and the outside of the cabinet 200, even if the second fan 400 rotates, the exchange of air between the cabinet 200 and the outside can be weakened to only a limited extent.
Unlike the first fan 320, the second fan 400 does not have a state in which the second window can be completely closed. Accordingly, the first fan 320 does not have a state of not affecting the exchange of air between the cabinet 200 and the outside at all.
The driving assembly 100 includes a first shaft 510 and a second shaft 530 disposed along a first direction, the first shaft 510 and the second shaft 530 synchronously rotate and can relatively slide along the first direction, the first shaft 510 and the second shaft 530 respectively pass through the first window and the second window, the first fan 320 is disposed on the first shaft 510 and synchronously rotates with the first shaft 510, and the second fan 400 is disposed on the second shaft 530 and synchronously rotates with the second shaft 530. It should be noted that the sliding of the first shaft 510 along the first direction does not drive the first fan 320 to slide along the first direction; the sliding of the second shaft 530 along the first direction can drive the second fan 400 to slide along the first direction.
Specifically, a first rotating ring 330 is further disposed outside the first shaft 510, a second rotating ring 450 is further disposed outside the second shaft 530, and a sleeve is disposed at one end of the second shaft 530 close to the first shaft 510. The first rotating ring 330 is connected with the sleeve as a whole by a plurality of connecting rods 550 along the first direction, the second rotating ring 450 is rotatably disposed at the second window, and the second rotating ring 450 does not move along the first direction. The first shaft 510 is disposed within the sleeve at an end thereof adjacent to the second shaft 530 and forms an expansion chamber 540 with the sleeve, and the expansion chamber 540 is filled with an expansion medium, which may be a liquid having a relatively high boiling point.
The first fan 320 and the second fan 400 have similar blade structures, and each of the blades has an outward protrusion formed at the root and the tip of the blade.
The first shaft 510 is provided with a first groove body along a first direction, and the root of the first fan 320 is protruded and located in the first groove body. The first rotating ring 330 is provided with a through hole, and the top protrusion of the fan blade of the first fan 320 is located in the through hole. Therefore, the blades of the first fan 320 can rotate, and when the first rotating ring 330 slides along the first direction, the first fan 320 can be driven to slide along the first direction. In addition, a first rack is also arranged in the first groove body, a first gear is arranged on the root protrusion of the fan blade of the first fan 320, and the first rack is meshed with the first gear; when the first shaft 510 slides along the first direction, the first rack drives the blades of the first fan 320 to rotate.
The second shaft 530 is provided with a mounting hole, and a root protrusion of the fan blade of the second fan 400 is located in the mounting hole. The second rotating ring 450 is provided with a second groove, and the top of the second fan 400 is protruded and located in the second groove. Thus, the blades of the second fan 400 can rotate, and when the second shaft 530 slides in the first direction, the second fan 400 can be driven to slide in the first direction. In addition, a second rack 451 and a limit groove 454 are further arranged in the second groove, correspondingly, a second gear 440 and a rotatable limit block 430 are arranged on a top projection of the fan blade of the second fan 400, the second gear 440 is engaged with the second rack 451, a first elastic member is arranged between the limit block 430 and the top projection, and the first elastic member always enables the second fan 400 to be in a third state; a second elastic member 460 is further disposed in the mounting hole, and the second elastic member 460 always keeps the second fan 400 in the fourth state; the elastic force of the second elastic member 460 is smaller than that of the first elastic member. The first and second elastic members 460 may be common elastic members such as coil springs.
A limiting rod 520 is disposed outside the sleeve, and the limiting rod 520 defines a lower limit position such that the second shaft 530 cannot pass the lower limit position when sliding in the first direction without limiting the upward movement of the second shaft 530. Thereby, it is ensured that the first shaft 510 is moved upwards instead of the second shaft 530 being moved downwards when the swelling medium swells.
A third elastic member 470310 is further disposed between the first rotating ring 330 and the housing 200, and the third elastic member 470310 always moves the first rotating ring 330 in a direction approaching the second rotating ring 450.
The driving assembly 100 always drives the first shaft 510 and the second shaft 530 to rotate.
When the 5G communication device is in the working state, in the initial state, the first fan 320 is in the first state, and the second fan 400 is in the third state. At this time, the second fan 400 rotates so that the external air enters the cabinet 200, but the air inside the cabinet 200 cannot be discharged through the first window, so that the air is accumulated in the cabinet 200.
After operating for a certain period of time, the 5G communication equipment generates a large amount of heat, which is accumulated inside the cabinet 200 to increase the temperature inside the cabinet 200. The expansion medium expands under the influence of temperature, driving the first shaft 510 to move upward, and the second shaft 530 does not move up and down. The first shaft 510 moves upward, and the first rack drives the blades of the first fan 320 to rotate, so that the first fan 320 enters the second state. At this time, the first fan 320 rotates to discharge the high temperature gas inside the cabinet 200, and the second fan 400 rotates to discharge the relatively cool gas outside the cabinet 200 into the cabinet 200, thereby achieving a cooling of the inside of the cabinet 200.
When the 5G communication device is in a standby state, the temperature inside the device is always low, the volume of the expansion medium is not changed, and the expansion cavity 540 is a closed cavity, and in this state, the first shaft 510 and the second shaft 530 move synchronously along the first direction.
In the initial state, the first fan 320 is in the first state, and the second fan 400 is in the third state. At this time, the second fan 400 rotates so that the external air enters the cabinet 200, but the air inside the cabinet 200 cannot be discharged through the first window, so that the air is accumulated in the cabinet 200. After a certain time, the pressure inside the casing 200 rises, and since the first fan 320 is in the first state, the air pressure inside the casing 200 pushes the first fan 320 to overcome the elastic force of the third elastic member 470310, and moves upward together with the first rotating ring 330 and the second shaft 530.
It should be noted that, although the first shaft 510 moves upward, the upward movement of the first shaft 510 is driven by the upward movement of the first rotating ring 330, and the amounts of the upward movement of the first rotating ring 330 and the first shaft 510 are the same, and the blades of the first fan 320 and the first rotating ring 330 do not move relatively along the first direction, so that the blades of the first fan 320 do not move relatively to the first shaft 510, and the blades of the first fan 320 do not deflect, that is, the first fan 320 is always in the first state.
The second shaft 530 moves upward to drive the second fan 400 to move upward. In the earlier stage of the movement, the limiting block 430 on the top protrusion of the fan blade of the second fan 400 is still located in the limiting groove 454, the second rack 451 drives the second gear 440 to rotate, so that the deflection angle of the fan blade of the second fan 400 is gradually increased, and further the capability of the second fan 400 to exhaust gas into the casing 200 is gradually enhanced, so that the second fan 400 can continuously exhaust gas into the casing 200 under the condition that the pressure inside the casing 200 is gradually increased.
At the later stage of the movement, the limiting block 430 is disengaged from the limiting groove 454, at this time, the first elastic member between the limiting block 430 and the fan blades of the second fan 400 is released, the limiting block 430 no longer limits the deflection of the fan blades of the second fan 400, the fan blades of the second fan 400 are rapidly deflected to the vertical state under the action of the second elastic member 460, that is, the second fan 400 enters the fourth state, and even if the second fan 400 rotates, the air exchange between the casing 200 and the outside can be weakened only to a limited extent. Since the second fan 400 enters the fourth state from the third state as an abrupt change process, the air inside the casing 200 is discharged at a high speed through the second window under the action of high pressure, and impacts the filter screen 410, so as to clean the filter screen 410.
After the inside of the cabinet 200 is released, the pressure is reduced, and the first shaft 510 and the second shaft 530 move downward by the self weight of the third elastic member 470310 and the plurality of members. In the downward movement process, the two sides of the limiting groove 454 are provided with limiting surfaces with different heights, and the limiting block 430 firstly abuts against the higher limiting surface and rotates, and then falls into the limiting groove 454, so that the force storage of the first elastic part is realized, and the limiting block 430 can be restored to the initial state.
It should be noted that, when the 5G communication device is always in the working state, after the cooling process is completed, since the temperature inside the casing 200 rises more slowly, the fan assembly 300 can also perform one or more dust removal processes after the cooling process. And because the amount of gas discharged during the dust removal process is not enough to take away all the heat inside the cabinet 200, the temperature inside the cabinet 200 is still continuously raised until the temperature inside the cabinet 200 reaches the level that needs to enter the cooling process.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
