Description

Technical Field

[0001] The utility model relates to the technical field of circulating dehumidification equipment, in particular to a circulating dehumidification device for an outdoor cabinet. Background Art

[0002] An outdoor cabinet is a terminal control and power distribution device used in power systems. It is usually installed in building scenes or industrial construction scenes to regulate the terminal output of the power system. Due to the large number of electronic components installed in the outdoor cabinet, it often generates a lot of heat during operation, which causes the temperature of its inner cavity space to continue to rise and gradually affect the normal operation of the electronic components. Therefore, in order to ensure the effective operation of the electronic components installed inside, it is usually necessary to set up an internally and externally connected heat dissipation structure to continuously transfer the heat in the inner cavity space, so as to reduce the working environment temperature of the electronic components and ensure their stable operation state, thereby improving the service life to a certain extent.

[0003] However, in southwest my country, there is a common problem of high humidity in the outside air. In the process of achieving air replacement, the heat dissipation structure is usually affected by the quality of the outside air and introduces more moisture into the cabinet, causing the humidity in the cabinet to rise sharply. When electronic components are in a high humidity environment for a long time, it is very easy to cause the electronic components to be corroded and damaged, resulting in faults such as short circuits, which reduces the service life of the electronic components. In addition, short circuits are also prone to overheating of wiring and pin positions. If not handled in time, it is very easy to spontaneously combust and cause fires, increasing the safety hazards during actual use. In addition, although some existing technologies have begun to set up dehumidification structures in the air intake channel to reduce the moisture contained in the heat dissipation airflow, due to the high humidity of the outside air in some areas, the existing dehumidification structure will be saturated after absorbing a certain amount of moisture and cannot continue to dehumidify effectively. It cannot be adapted to the cabinets that work for a long time, and the staff needs to regularly replace and maintain the dehumidification structure, which increases the workload and continuous dehumidification efficiency.

The cabinet shell 1 is provided with a mounting plate 5 capable of separating the first through-hole 11 for installing the air intake component 2 and the second through-hole 12 for installing the exhaust component 3 to define a flow guide path. Preferably, a plurality of electronic components are detachably mounted on the mounting plate 5, so that the airflow flowing directionally along the surface of the mounting plate 5 can effectively take away the heat generated when the electronic components are working. The top of the cabinet housing 1 is provided with a shielding top 6, and the shielding top 6 is inlaid with a solar panel 7. The circulating dehumidification component 4 provided in the present application can adjust the working position of its different drying frames 44 according to the weight of water absorption, so that the drying frame 44 that is saturated with water absorption can be rotated to swap the working position with the drying frame 44 that has not absorbed water or has completed secondary dehumidification and drying, so that the drying frame 44 of the circulating dehumidification component 4 in the air intake component 2 always remains in an unsaturated state and continues to dry and dehumidify the external air entering the cabinet housing 1 from the air intake channel defined by the air intake component 2, ensuring that the heat dissipation airflow entering the cabinet housing 1 has a certain degree of dryness, so as to avoid the formation of a high humidity environment in the cabinet housing 1 and affect the normal operation of the electronic components, and provide a guarantee for the maintenance of the long-term working life of the electronic components.

In addition, the exhaust component 3 can also perform secondary heating on the heat-absorbing and heated heat-dissipating airflow to ensure that the airflow can efficiently and fully take away the moisture in the drying frame 44, ensuring the efficiency and quality of secondary drying, so that the dried drying frame 44 can be moved to the air intake component 2 for secondary drying and dehumidification. The circulating dehumidification component 4 provided in the present application can periodically adjust the positions of different drying frames 44 according to the changes in its own water absorption and weight gain, so as to ensure that it can continuously and effectively dry the heat-dissipating airflow input by the air intake component 2.

The double-position air intake drive structure provided in the present application can ensure the effectiveness of the air intake and the adequacy of the drying, so as to ensure the dryness of the heat dissipation airflow. The present application avoids the disadvantage of the initial temperature of the airflow being too high due to the intersection of the introduced airflow and the discharged high-temperature airflow by providing an air intake elbow 23, thereby improving the heat dissipation efficiency.

Preferably, the lifting spherical shell 35 refers to a hemispherical mesh structure, which can lift up and move to the drying frame 44 in the second filling slot 311 to achieve the disconnection of the relevant closed circuit. The lifting ball shell 35 provided in the present application can lift up the drying frame 44 when the drying frame 44 is screwed into the second tube body 31 to disconnect the pressure touch switch 45, so that the water-saturated drying frame 44 can be effectively dried in the exhaust assembly 3. The exhaust assembly 3 provided in the present application can utilize the heat-dissipating airflow after absorbing heat and the secondary heating of the heat-dissipating airflow after absorbing heat by the heating net 34 to increase the temperature of the external exhaust airflow, thereby improving the drying efficiency and quality of the drying frame 44, so that the drying frame 44 still has strong performance and efficiency when performing secondary drying and dehumidification treatment in the air intake assembly 2.

Further preferably, a soft spring 433 capable of supporting the drying frame 44 is detachably installed in the positioning installation hole 432, so that when the drying frame 44 absorbs moisture and increases weight, it is further compressed to make the drying frame 44 descend relative to the positioning connection shell 43, so that the pressure touch switch 45 provided between the positioning connection shell 43 and the drying frame 44 is closed, and then the rotating motor 41 is powered on to drive the positioning connection shell 43 and the drying frame 44 in the first filling slot 211 to move to the second filling slot 311.

Preferably, the circumferential length of the lower end frame of the drying frame 44 with a small diameter cross section is greater than the height of the limiting step constructed by the through hole 431, so that the drying frame 44 decreases to a certain extent when the mass increases due to dehumidification and water absorption, so that at least part of the lower end frame of the drying frame 44 moves to the outside of the through hole 431. When the drying frame 44 that absorbs moisture and gains weight moves to the second filling groove 311, the drying frame 44 rises under the support of the lifting ball shell 35, thereby disconnecting the pressure touch switch 45 that is driven to close by the drying frame 44 downstream of the weight gain, so that the drying frame 44 that absorbs moisture and gains weight can use the hot air flow transported to the outside to dry and dehumidify.
