Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation, and in particular to an outdoor cabinet with a heat dissipation energy-saving circulation system. Background Art

[0002] At present, outdoor communication equipment cabinets generally use customized precision air conditioners to dissipate heat from the communication equipment in the cabinets. The energy consumption of refrigeration equipment accounts for half of the energy consumption of the entire outdoor communication equipment cabinet. Reducing the energy consumption of refrigeration equipment is an urgent problem to be solved. At present, there are precision air conditioners, direct ventilation, heat exchangers and other methods for temperature control of outdoor communication equipment cabinets. Saving energy and protecting the environment have become a consensus of the whole society. These methods will consume a lot of energy and are not energy-saving and environmentally friendly.

[0003] As the external environment changes with the climate, wind often blows in all directions, which can be used to naturally dissipate heat inside the outdoor cabinet. However, there may be no wind in the external environment for a long time, so it is still necessary to dissipate heat during the time when there is no natural wind to better protect the electronic components. Moreover, when the humidity of the outside air is high, the introduced outside wind can easily cause excessive humidity inside the outdoor cabinet. Dehumidification is required in time to better protect the electronic components inside the outdoor cabinet.

[0004] In response to the above technical problems, Chinese patent application number: CN202120125908.0, an outdoor cabinet that is easy to dissipate heat, by adjusting the angle of the blades in the heat dissipation window, the ventilation volume of the heat dissipation window can be adjusted, and the ventilation volume can be adjusted from maximum to minimum. When adjusted to the minimum, the heat dissipation window is closed, and dust or other magazines can be prevented from entering. When adjusted to the maximum, the heat dissipation effect of the heat dissipation window in conjunction with the heat dissipation fan is the best.

[0034] See also Figures 1 to 8 The present invention provides a technical solution: an outdoor cabinet with a heat dissipation and energy-saving circulation system, wherein the front end of the cabinet shell 1 of the outdoor cabinet is hinged with an outer cover 2 for closing the cabinet shell 1, the cabinet shell 1 comprises a heat dissipation mechanism and a sealing mechanism, the heat dissipation mechanism comprises an energy-saving air intake module, a compensation air intake module and a circulation dehumidification module, the energy-saving air intake module can use natural wind power to dissipate heat for electronic components inside the cabinet shell 1, and has high energy saving efficiency, the compensation air intake module is used to compensate for wind power for heat dissipation when the wind power is insufficient, and the circulation dehumidification module is used to evaporate and discharge the filtered moisture, so as to continuously filter the air entering and exiting with the wind, and reduce the humidity in the cabinet shell 1, such as Figure 2 and Figure 3 as well as Figure 5As shown, as the external environment changes with the climate, winds often blow in all directions, which can be used naturally for heat dissipation. The energy-saving air inlet module includes an air inlet tube 3 arranged at the upper end of the cabinet shell 1, and a plurality of wind collecting buckets 4 are evenly arranged on the outside of the air inlet tube 3. The air inlet inside the wind collecting bucket 4 is provided with a first non-return valve 5, and the bottom end of the first non-return valve 5 is connected with an air inlet channel 6 opened inside the cabinet shell 1. One end of the air inlet channel 6 is connected with a plurality of groups of nozzles 9 through an air distribution cavity 7 and an exhaust channel 8. A heat dissipation hole 11 is opened on the side of the cabinet shell 1 away from the nozzle 9, and a second non-return valve 15 is arranged in the other end of the air inlet channel 6. The wind collecting bucket 4 is arranged in a truncated cone shape, and a bellows 10 is arranged on the connecting pipe of the nozzle 9. The outer end of the heat dissipation hole 11 is arranged to tilt downward. When in use, one or two of the wind collecting buckets 4 are used to dissipate the heat from all directions. The natural wind is collected, the first one-way valve 5 can prevent the wind from flowing back, avoid mutual interference between the wind collecting buckets 4, and ensure the air intake effect of the wind collecting bucket 4. Then the natural wind enters the air inlet channel 6 through the air inlet tube 3. The air inlet channel 6 evenly distributes the wind to each nozzle 9 through the air distribution cavity 7. The nozzle 9 can select the spray angle through the bellows 10, which is convenient for precise alignment of the various electronic components inside the cabinet shell 1. Finally, the natural wind takes away the heat of each electronic component and discharges it from the heat dissipation hole 11, which is conducive to introducing natural wind in nature to accurately dissipate the heat of each electronic component inside the cabinet shell 1, which can not only save the energy required for heat dissipation, but also can be reused. By tilting the heat dissipation hole 11, not only can the hot air be discharged normally, but also the external rainwater can be prevented from flowing into the cabinet shell 1, thereby causing the electronic components inside the cabinet shell 1 to get damp.

[0035] As an embodiment of the present invention, Figure 1 and Figure 2 as well as Figure 4 As shown, because the external environment may also be without natural wind for a long time, it is still necessary to dissipate heat during the time when there is no natural wind in order to better protect the electronic components. The compensation air inlet module includes a fan chamber 12 opened on one side of the air inlet channel 6 inside the cabinet shell 1, an axial flow fan 13 is arranged on the inner wall of one side of the fan chamber 12, and an air inlet hole 14 is arranged on the inner wall of the other side of the fan chamber 12. A temperature sensor 16 is arranged on the top of the inner part of the cabinet shell 1, and a controller 23 is arranged on the front end of the cabinet shell 1. When in use, the temperature sensor 16 senses the temperature inside the cabinet shell 1 in real time and The temperature information is transmitted to the controller 23. When the controller 23 analyzes and obtains a high temperature result, it instructs the axial flow fan 13 to start. The axial flow fan 13 introduces the external wind force into the air inlet channel 6 through the fan cavity 12 through the air inlet hole 14, so that the nozzle 9 can dissipate heat for the electronic components inside the cabinet shell 1, which is beneficial for real-time monitoring of the temperature inside the cabinet shell 1 and makes up for the defect when the natural wind is insufficient. In addition, by setting the second one-way valve 15, it is convenient for the axial flow fan 13 to quickly introduce wind force through the air inlet hole 14, and it can also prevent the waste caused by the exhaust of natural wind through the air inlet hole 14.

[0036] As an embodiment of the present invention, Figure 3 and Figure 4 as well as Figure 7 As shown, with the change of climate, when the humidity of the outside air is high, the introduction of outside wind can easily lead to excessive humidity inside the cabinet shell 1. The circulating dehumidification module includes a stepper motor 17 arranged inside the cabinet shell 1. The output shaft of the stepper motor 17 is fixedly connected to a rotating rod 18. Four groups of silica gel drying filter layers 19 are evenly arranged around the rotating rod 18. One group of the four groups of silica gel drying filter layers 19 is stuck in the air inlet channel 6. One group of the four groups of silica gel drying filter layers 19 is stuck in a drying chamber 20. The drying chamber 20 is opened inside the cabinet shell 1. The inner wall of the drying chamber 20 is provided with a dryer 21 for drying the silica gel drying filter layer 19. An evaporation hole 22 is provided at the front end of the cavity 20. When in use, wind can filter out most of the moisture through the silica gel drying filter layer 19, effectively reducing the humidity of the air entering the cabinet shell 1. Then the stepper motor 17 drives the silica gel drying filter layer 19 to rotate intermittently through the rotating rod 18, and continuously replaces the silica gel drying filter layer 19 to ensure the filtering effect of the silica gel drying filter layer 19. Then the filtered silica gel drying filter layer 19 enters the drying cavity 20, and the dryer 21 in the drying cavity 20 evaporates the moisture in the silica gel drying filter layer 19 and discharges it from the evaporation hole 22, which is convenient for the cyclic use of the silica gel drying filter layer 19 to ensure the dehumidification effect.

[0037] As an embodiment of the present invention, Figure 5 and Figure 6 as well as Figure 8As shown, when the outer cover 2 is opened or the gap between the outer cover 2 and the cabinet shell 1 is too large, the air flow is large, which makes it easy for the temperature sensor 16 to detect wrong information, causing the axial flow fan 13 to start incorrectly, thereby wasting energy. The sealing mechanism includes an air sealing module and a starting module. The air sealing module includes a groove 24 opened at the front end of the cabinet shell 1, and the inner wall of the groove 24 is rotatably connected to one end of a screw rod 25, and the other end of the screw rod 25 is fixedly connected to a knob 26.

The expansion airbag 32 is annular The starting module is set up to include a first electrode spring 29 fixed on the inner wall of one side of the telescopic airbag 28, and a second electrode spring 30 is fixedly installed on the other side of the inner wall of the first electrode spring 29. When in use, the knob 26 is turned, and the knob 26 drives the movable plate 27 to move through the screw rod 25, and the movable plate 27 drives the telescopic airbag 28 to contract. The gas in the telescopic airbag 28 enters the expansion airbag 32 through the gas pipe 31, and the expansion airbag 32 expands to seal the gap between the cabinet shell 1 and the outer cover 2. Then the first electrode spring 29 inside the telescopic airbag 28 contacts the second electrode spring 30 to connect the temperature sensor 16, and the temperature sensor 16 starts to detect the internal temperature of the cabinet shell 1, which is conducive to opening and closing the temperature sensor 16 to avoid the temperature sensor 16 from monitoring erroneous information, and can seal the gap between the cabinet shell 1 and the outer cover 2 to avoid a large amount of external rain and moisture from entering.
