Some embodiments of the present disclosure provide a temperature control device, as shown in fig. 1, the temperature control device 20 includes a partition 30, a first fan 401, a second fan 402, an evaporator 50, a compressor 60, a condenser 70, and an air valve 80. Illustratively, the temperature control device 20 is mounted on the cabinet 10 of the base station.

The partition 30 divides the internal space of the temperature control device 20 into a first space 201 and a second space 202. The baffle 30 is provided with a hole 301, and for example, as shown in fig. 1 and fig. 2, the hole 301 is disposed at a position far away from the second fan 402. For example, as shown in fig. 3, the hole 301 may also be disposed near the second fan 402. The present disclosure is not limited to a specific arrangement position of the hole 301 on the partition plate 30.

The first fan 401 and the evaporator 50 are disposed in the first space 201, and an air outlet 4011 of the first fan 401 is disposed on the temperature control device 20 and near the cabinet 10. The second fan 402, the compressor 60, and the condenser 70 are disposed in the second space, and the air inlet 4021 of the second fan 402 is disposed on the temperature control device 20 at a position far from the cabinet 10. As shown in fig. 5, the first fan 401 and the second fan 402 are both coupled to the battery V2, and the battery V2 is configured to supply power to the first fan 401 and the second fan 402 when the utility power source V1 is powered off. As shown in fig. 5, the compressor 60 is configured to be coupled to the mains supply V1, and the compressor 60 is configured to operate at a fixed frequency when the mains supply V1 is powered.

In some embodiments, the first fan 401 and the second fan 402 are further configured to be coupled to a mains supply V1, and when the mains supply V1 supplies power, the first fan 401 and the second fan 402 are powered by the mains supply; when the commercial power supply V1 is powered off, the first fan 401 and the second fan 402 are powered by the storage battery V2.

The air valve 80 is disposed on the partition plate 30 near the hole 301, and the air valve 80 is rotatably connected to the partition plate 30. When the commercial power source V1 supplies power, the air valve 80 is closed, the air valve 80 blocks the hole 301, and the air in the first space 401 and the air in the second space 402 cannot circulate. When the utility power supply V1 is powered off, the damper 80 is opened, and the air in the first space 401 and the air in the second space 402 circulate through the holes 301.

In some embodiments, as shown in fig. 5, the temperature control device 20 further includes a damper controller 802. The damper controller 802 is coupled to the damper 80 and the battery V2. In some embodiments, as shown in fig. 2, the air valve 80 is fixedly connected to the rotating shaft 801, the rotating shaft 801 is rotatably connected to the partition 30, and the rotating shaft 801 is coupled to the air valve controller 802, and the air valve controller 802 controls the air valve 80 to open or close by controlling the rotating shaft 801. For example, the direction of rotation of the damper 80 may be in the direction of the arrow shown in FIG. 1. The present disclosure is not limited to the specific manner of rotationally connecting the air valve 80 and the partition plate 30, and for example, the air valve 80 may also be rotationally connected with the partition plate 30 by a pin or a hinge.

For example, as shown in fig. 4, when the damper controller 802 controls the damper 80 to rotate to the first position, the damper 80 is closed, and the damper 80 blocks the hole 301, so that the air in the first space 401 and the air in the second space 402 cannot flow through. As shown in fig. 1 or fig. 3, when the damper controller 802 controls the damper 80 to rotate to the second position, the damper 80 is opened, and the air in the first space 401 is communicated with the air in the second space 402 through the hole 301, for example, the air may flow in the direction of the arrow shown in fig. 3. It is understood that the second position of the air valve 80 can be a position where the air valve 80 does not block the hole 301, and the included angle between the air valve 80 and the partition plate 30 can be different, such as 30 °, such as 90 °.

In some embodiments, the damper controller 802 may be a relay. The relay comprises a coil and a first contact, wherein the coil is coupled to a storage battery V2, when a mains supply V1 supplies power, the coil loses power, the first contact is in a first state, an air valve 80 is located in a second position, when the mains supply V1 loses power, the coil gets power, the first contact is in a second state, and the air valve 80 is located in the first position. If the first contact is a normally closed contact, the first state of the first contact is closed, and the second state of the first contact is open. Or, if the first contact is a normally open contact, the first state of the first contact is open, and the second state of the first contact is closed.

For example, as shown in fig. 1 to 5, the evaporator 50 is coupled to the compressor 60, the condenser 70 and the commercial power source V1, and the condenser 70 is coupled to the compressor 60 and the commercial power source V1.

In the above embodiment, when the commercial power source V1 supplies power, the first fan 401, the second fan 402, the evaporator 50, the compressor 60, and the condenser 70 can all operate normally to reduce the temperature in the cabinet 10 of the base station, and the principle is similar to that of conventional air-conditioning refrigeration. For example, the evaporator 50, the compressor 60, and the condenser 70 may be set to automatically operate, for example, when the return air temperature T is greater than or equal to Tc, the evaporator 50, the compressor 60, and the condenser 70 are turned on, and when the return air temperature T is less than or equal to Tc-Td, the operation of the evaporator 50, the compressor 60, and the condenser 70 is stopped. Wherein Tc is a set temperature, td is a refrigeration return difference, and both the set temperature Tc and the refrigeration return difference Td can be set by a user, for example, the user can set Tc to 30 ℃ and Td to 5 ℃.

Meanwhile, the air valve 80 is controlled by the air valve controller 802 to rotate to the first position as shown in fig. 4, so that the air valve 80 can block the hole 301, and further, gas exchange between the first space 201 and the second space 202 cannot be performed. At this time, as shown by an arrow in fig. 4, hot air in the cabinet 10 flows into the first space 201 through the air outlet 4011 of the first fan 401, in the process of heat absorption and evaporation of the refrigerant in the evaporator 50, cold energy is continuously released into the cabinet 10 of the base station along the arrow direction around the evaporator 50 shown in fig. 4, at this time, the air valve 80 is closed, air with higher temperature in the second space 202 cannot enter the first space 201 through the holes 301, and cold energy cannot enter the second space 202 through the holes 301, thereby avoiding unnecessary loss of cold air. After the refrigerant is compressed by the compressor 60, heat is released to the outside of the condenser 70 in the direction of the arrows around the condenser 70 shown in fig. 4 in the process of condensing the compressed refrigerant into a liquid phase by the condenser 70. Because the air valve 80 is closed at this time, air with a higher temperature in the second space 202 cannot enter the first space 201 through the hole 301, and further cannot enter the cabinet 10 of the base station, so that a better cooling effect can be ensured.

When the utility power supply V1 is powered off, the power supplies of the evaporator 50, the compressor 60 and the condenser 70 are interrupted, and the first fan 401, the second fan 402 and the air valve controller 802 can normally operate due to the power supply of the storage battery V2, at this time, as shown in the arrow direction in fig. 3, the air outside the temperature control device 20 can sequentially enter the second space 202 through the air opening 4021 of the second fan 402, then enter the first space 201 through the hole 301, and then reach the inside of the cabinet 10 through the air opening 4011 of the first fan 401, thereby reducing the temperature inside the cabinet 10.

In some embodiments, when the power supply V1 is initially powered off, a part of the cool air is stored in the cabinet 10, and the first fan 401, the second fan 402 and the air valve controller 802 may be temporarily deactivated to prevent the cool air from flowing out of the cabinet 10 as much as possible. Instead, the first fan 401, the second fan 402 and the air valve controller 802 are activated when the return air temperature of the cabinet 10 is within a certain range, and when the return air temperature reaches the temperature within the certain range, the first fan 401 and the second fan 402 are activated, and the air valve 80 is controlled by the air valve controller 802 to rotate to the second position, so as to open the air valve 80, so that the air outside the temperature control device 20 enters the cabinet 10 of the base station in the direction of the arrow shown in fig. 3. The air entering the base station cabinet 10 can be exhausted through the air outlet of the cabinet 10, so as to reduce the temperature in the base station cabinet 10. For example, the return air temperature may be a temperature measured at the air outlet 4011 of the first fan 401, or may be a temperature measured at the air outlet of the cabinet 10, and may be measured by a temperature sensor.

Illustratively, when T < (Tv- Δ Tv 2) or (T-Ta) < 1 deg.C, the rotation of the damper 80 to the first position may be controlled by the damper controller 802. T < (Tv- Δ Tv 2), which means that the return air temperature T is lower than the ventilation start temperature Tv, (T-Ta) < 1 ℃, which means that the return air temperature is closer to the ambient temperature, and the air in the cabinet 10 does not need to be cooled, so the first fan 401, the second fan 402 and the air valve controller 802 may not be started. For example, the temperature Tv of the start of ventilation, the difference Δ Tv1 of the start of ventilation, and the difference Δ Tv2 of the stop of ventilation may be set by the user, for example, the temperature Tv of the start of ventilation may be set to 25 ℃, and the difference Δ Tv1 of the start of ventilation and the difference Δ Tv2 of the stop of ventilation may be set to 5 ℃.

Illustratively, the air valve 80 may be controlled by the air valve controller 802 to rotate to the second position when Tv ≦ T < Tc, and (T-Ta) ≧ Δ Tv1, where Tv is the temperature at which ventilation starts, ta is the actual temperature of the environment, Δ Tv1 is the second fan start return difference, and Δ Tv2 is the second fan stop return difference. Tv is less than or equal to T and less than Tc, which indicates that the return air temperature reaches higher temperature, (T-Ta) is more than or equal to delta Tv1, which indicates that the temperature difference between the return air temperature and the actual temperature of the environment is larger, and when the return air temperature T meets the two conditions, the air temperature in the cabinet 10 is higher and needs to be cooled. At this time, the damper 80 is controlled by the damper controller 802 to rotate to the second position, so that the environment outside the cabinet 10 can be used to exchange air with the cabinet 10 to cool down.

In some embodiments, as shown in fig. 5, the air outlet 4021 of the second fan 402 is provided with a filter screen (not shown) and a self-cleaning device 4022 for cleaning the filter screen, and the self-cleaning device 4022 is coupled to the mains V1. The filter screen may filter air entering the inside of the cabinet 10 from the tuyere 4021 of the second fan 402 to prevent dust from entering the inside of the cabinet 10. The self-cleaning device 4022 is used to clean the filter net, and for example, a timed cleaning may be set to the self-cleaning device 4022. The self-cleaning device 4022 is powered only by the mains supply V1, so that unnecessary loss of the storage battery V2 when the mains supply V1 is powered off can be avoided.

Some embodiments of the present disclosure further provide a base station, as shown in fig. 1 to 6, the base station includes a cabinet 10, a communication device 100 disposed in the cabinet 10, and a temperature control device 20 as described in any of the above embodiments. The communication device 100 is coupled to the mains supply V1 and the battery V2.

When the utility power supply V1 supplies power, the communication device 100, the evaporator 50, the compressor 60, and the condenser 70 may operate under the voltage provided by the utility power supply V1, the communication device 100 ensures a normal communication function, and the evaporator 50, the compressor 60, and the condenser 70 control the temperature in the base station cabinet 10 together. When the utility power supply V1 is powered off, the communication device 100, the first fan 401, the second fan 402 and the air valve controller 802 may operate under the voltage provided by the storage battery V2, the communication device 100 ensures a normal communication function, and the first fan 401, the second fan 402 and the air valve controller 802 control the temperature in the base station cabinet 10 together.

In some embodiments, as shown in fig. 5 and 6, the communication device 100 includes a master device 101 and a transmitting device 102. The first fan 401, the second fan 402, the blast gate controller 802 and the main device 101 are coupled to the first power down breaker S1, and the transmission device 102 is coupled to the second power down breaker S2. The primary power down breaker S1 and the secondary power down breaker S2 are coupled to the battery V2. When the utility power supply V1 is powered off, the primary power-off breaker S1 and the secondary power-off breaker S2 are both closed to supply power to the main device 101, the transmission device 102, the first fan 401, the second fan 402, and the damper controller 802. In order to ensure the basic function of the base station as a transmission station, the operation time of the transmission equipment 102 needs to be prolonged as much as possible, so that when the electric quantity of the storage battery V2 is low, the primary power-off breaker S1 is controlled to be switched from the closed state to the open state, and the secondary power-off breaker S2 is controlled to be kept in the closed state. For example, when the remaining 10% of the electric quantity of the storage battery V2 is, the one-time power-off circuit breaker S1 is controlled to be switched from the closed state to the open state, and at this time, the main device 101, the first fan 401, the second fan 402, and the damper controller 802 do not work any more, and only the transmission device 102 is kept operating.

In some embodiments, the base station further includes a lightning protection sheet 90, the lightning protection sheet 90 being coupled to the compressor 60. Since the compressor 60 is powered by the commercial power source V1, and the commercial power source V1 is an ac power source, the lightning protection plate 90 can prevent the compressor 60 from being damaged by lightning.

The above description is only for the specific embodiments of the present disclosure, but the scope of the present disclosure is not limited thereto, and any person skilled in the art will appreciate that changes or substitutions within the technical scope of the present disclosure are included in the scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
