Description

Technical Field

[0001] This utility model relates to the field of UPS uninterruptible power supply technology, and in particular to a dustproof and moisture-proof UPS uninterruptible power supply. Background Technology

[0002] A UPS (Uninterruptible Power Supply) is an uninterruptible power supply containing an energy storage device. It is a system device that converts DC power from a battery into AC power through modules such as the main unit inverter. It is mainly used for equipment with high power stability requirements. When the AC power is normal, the UPS can act as a voltage regulator to protect the electrical equipment and charge the battery at the same time. When the AC power is interrupted, the UPS will switch to backup power to supply power to the equipment.

[0003] Because UPS power supplies generate a lot of heat during operation, they need to be designed with heat dissipation holes. However, external dust, moisture, and other impurities can enter the UPS power supply through these holes, which will seriously affect its lifespan over time, especially when operating in harsh environments. Therefore, there is a need for a dustproof and moisture-proof UPS power supply to adapt to complex working environments. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof and moisture-proof UPS (Uninterruptible Power Supply) to solve the problem of external dust and moisture entering the UPS power supply and affecting its service life.

[0005] To achieve the above objectives, this utility model provides a dustproof and moisture-proof UPS uninterruptible power supply, including a housing, a frame and a back plate arranged in the housing, and a cavity formed by the frame, housing and back plate, in which power supply components and dustproof and moisture-proof components are arranged.

[0006] The power supply assembly includes a power battery, a control circuit board, and an inverter. The power battery, control circuit board, and inverter are all mounted on a rack, and the power battery and inverter are electrically connected to the control circuit board.

[0007] The dust and moisture protection components include an air inlet chamber, an air guide chamber, a cooling fan, a dustproof grille, and a dehumidifier block. The air inlet chamber is detachably installed on the back panel, and the air guide chamber is detachably installed in the casing. The air inlet chamber and the air guide chamber are connected. An exhaust vent is provided on the air guide chamber, and the cooling fan is installed at the exhaust vent and electrically connected to the control circuit board. The dustproof grille is installed in the air inlet chamber, and the dehumidifier block is installed in the air guide chamber. An exhaust vent is provided at the bottom of the casing. External airflow enters the air guide chamber through the air inlet chamber. During this process, the external airflow passes through the dustproof grille and the dehumidifier block in sequence, and then the cooling fan blows the external airflow into the chamber. The airflow in the chamber is then discharged through the exhaust vent.

[0008] Furthermore, multiple adsorption plates are interspersed in the dustproof grille, and the adsorption plates are electrically connected to the control circuit board. Ribbons are provided on the dehumidification block.

[0009] Furthermore, the air inlet cavity is equipped with an opening and closing assembly, which includes a flipping drive and multiple sets of flaps. The multiple sets of flaps are sequentially installed and cover each other in the air inlet cavity. The external airflow must pass through the flaps and then through the dustproof grille. The flipping drive is installed on the air inlet cavity and is used to drive the flaps to flip.

[0010] Furthermore, a handle cavity is provided on the air inlet cavity. The handle cavity is not connected to the chamber. A detachable handle that can slide in the handle cavity is provided.

[0011] Furthermore, an internal circulation exhaust is installed near the dehumidification block in the air guide cavity; a transparent block is also installed on the air guide cavity, and the transparent block penetrates the casing.

[0012] Furthermore, an isolation plate is provided at the air outlet, and a disassembly part is provided on the isolation plate, and a groove is provided on the housing to fit the disassembly part.

[0013] Furthermore, a main switch, a charging port, and multiple power sockets are provided on the back panel, all of which are electrically connected to the control circuit board.

[0014] Furthermore, an operation panel is installed on the frame, and the operation panel is electrically connected to the control circuit board.

[0015] Furthermore, feet are provided at the bottom of the casing, and a handle is provided at the top of the casing.

[0016] This utility model provides a dustproof and moisture-proof UPS uninterruptible power supply. When heat dissipation is required, a flip-up drive controls the flap to open, allowing external airflow to enter. The airflow passes sequentially through a dustproof grille and a dehumidifying block. The dustproof grille adsorbs dust from the air, and the dehumidifying block adsorbs water vapor. The filtered airflow is then blown into the chamber by a cooling fan to dissipate heat from the electronic components, and then blown out from the exhaust vent. The dustproof grille and dehumidifying block effectively prevent dust and moisture from entering the chamber and affecting the service life of the electronic components, effectively protecting the UPS uninterruptible power supply.

[0038] The present invention will be described in detail below with reference to specific embodiments.

[0039] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0040] like Figures 1 to 13 As shown, this utility model provides a dustproof and moisture-proof UPS uninterruptible power supply, including a housing 1, a frame 2 and a back plate 3 are arranged in the housing 1, and a cavity is formed between the frame 2, the housing 1 and the back plate 3, and a power supply component 4 and a dustproof and moisture-proof component 5 are arranged in the cavity.

[0041] Power supply assembly 4 includes power battery 40, control circuit board 41 and inverter 42. Power battery 40, control circuit board 41 and inverter 42 are all mounted on rack 2. Power battery 40 and inverter 42 are electrically connected to control circuit board 41 respectively.

[0042] The dustproof and moisture-proof component 5 includes an air inlet chamber 50, an air guide chamber 51, a cooling fan 53, a dustproof grille 55, and a dehumidifier block 52. The air inlet chamber 50 is detachably installed on the back panel 3, and the air guide chamber 51 is detachably installed in the housing 1. The air inlet chamber 50 and the air guide chamber 51 are connected. An exhaust port is provided on the air guide chamber 51. The cooling fan 53 is installed at the exhaust port and is electrically connected to the control circuit board 41. The dustproof grille 55 is installed in the air inlet chamber 50, and the dehumidifier block 52 is installed in the air guide chamber 51. An exhaust vent 10 is provided at the bottom of the housing 1. External airflow enters the air guide chamber 51 through the air inlet chamber 50. During this process, the external airflow passes through the dustproof grille 55 and the dehumidifier block 52 in sequence, and is then blown into the chamber by the cooling fan 53. The airflow in the chamber is then discharged through the exhaust vent 10.

[0043] The dehumidifier block 52 and the dustproof grille 55 can effectively filter out dust and moisture in the air, making the air entering the chamber clean and dry enough.

[0044] In this embodiment, multiple sets of adsorption plates 550 are staggered in the dustproof grille 55, the adsorption plates 550 are electrically connected to the control circuit board 41, and a ribbon 520 is provided on the dehumidification block 52.

[0045] With the above design, during heat dissipation, the control circuit board 41 can supply a weak current to the adsorption plate 550, thereby creating a weak electrostatic field between the multiple adsorption plates 550. The electrostatic adsorption effect causes dust passing through the adsorption plates 550 to automatically adhere to them. The ribbon 520 on the dehumidifier block 52 allows for easy removal of the dehumidifier block 52 from the air guide cavity 51 during replacement.

[0046] In this embodiment, an opening and closing assembly 6 is provided on the air inlet cavity 50. The opening and closing assembly 6 includes a flipping drive 60 and multiple sets of flaps 61. The multiple sets of flaps 61 are sequentially installed and covered in the air inlet cavity 50. The external airflow needs to pass through the flaps 61 and then through the dustproof grille 55. The flipping drive 60 is installed on the air inlet cavity 50 and is used to drive the flaps 61 to flip.

[0047] When multiple sets of flaps 61 cover the air inlet cavity 50 in sequence, the air inlet cavity 50 will be blocked. At this time, impurities in the outside air will have difficulty entering the air inlet cavity 50, thus avoiding the workload of the dustproof grille 55 and dehumidification block 52 when stationary, and improving the service life of the dustproof grille 55 and dehumidification block 52. When heat dissipation is required, the flipping drive 60 drives the flaps 61 to rotate at a certain angle (e.g., Figure 13 As shown in the figure, the air inlet chamber 50 is in the open state, at which time outside air can freely enter the air inlet chamber 50.

[0048] In this embodiment, a handle cavity 500 is provided on the air inlet cavity 50. The handle cavity 500 is not connected to the chamber. A detachable handle 501 that can slide in the handle cavity 500 is provided in the handle cavity 500.

[0049] In this embodiment, the air inlet cavity 50 is fixedly installed on the back plate 3 with screws, and sealing rings are provided at the connection points between the air inlet cavity 50 and the back plate 3, and between the air inlet cavity 50 and the air guide cavity 51. After long-term operation, the dust accumulated in the dustproof grille 55 will affect the air intake efficiency and adsorption effect, and the increased moisture in the dehumidification block 52 will also affect the dehumidification effect. At this time, it is necessary to replace the dustproof grille 55 and the dehumidification block 52. When performing the replacement operation, the operator can first remove the screws, and then tilt the UPS uninterruptible power supply to slide the disassembly handle 501 out of the handle cavity 500. With the help of the disassembly handle 501, the operator can easily remove the entire air inlet cavity 50 from the back plate 3, which facilitates the replacement of the flip drive component 60 or the dustproof grille 55 installed on the air inlet cavity 50. After removing the air inlet cavity 50, a large opening will appear on the back panel 3. At this time, the staff can directly put their hand into the opening and pull the ribbon 520 on the dehumidifier 52 to remove the dehumidifier 52, and then replace it with a new dehumidifier 52.

[0050] In this embodiment, a power contact is provided on the air inlet cavity 50, and a corresponding power contact is also provided on the back plate 3. When the air inlet cavity 50 is installed in place, the two power contacts come into contact to connect the circuit, and the flip drive 60 and the dustproof grille 55 are electrically connected to the control circuit board 41 respectively.

[0051] In this embodiment, an internal circulation exhaust 510 is provided in the air guide cavity 51 near the dehumidifier block 52; a transparent block 54 is also provided on the air guide cavity 51, and the transparent block 54 penetrates the casing 1. In this embodiment, the dehumidifier block 52 is composed of silica gel desiccant. After absorbing water, the silica gel desiccant will undergo a color reaction and change its color. The user can observe the color of the dehumidifier through the transparent block 54 to determine whether it needs to be replaced. The internal circulation exhaust 510 is used for internal circulation dehumidification. When internal dehumidification is required, the flip drive 60 controls the flap 61 to close, blocking the air inlet cavity 50. Then the cooling fan 53 starts. Since the outside airflow can no longer enter from the air inlet cavity 50, a negative pressure area is generated in the air guide cavity 51 under the action of the cooling fan 53. Under the traction of the negative pressure area, the air in the chamber will enter the air guide cavity 51 from the internal circulation exhaust 510. The airflow entering from the internal circulation exhaust 510 will pass through the dehumidification block 52 and then be blown out by the cooling fan 53. The purpose of internal dehumidification is achieved by circulating the internal airflow through the dehumidification block 52.

[0052] In this embodiment, an isolation plate 13 is provided at the air outlet 10, and a disassembly part 14 is provided on the isolation plate 13. A groove is provided on the housing 1 to fit the disassembly part 14. The isolation plate 13 at the air outlet 10 can prevent dust from entering the cavity from the air outlet 10 when the unit is stationary. When the isolation plate 13 needs to be replaced, the user can directly pull the disassembly part 14 to remove the isolation plate 13 from the air outlet 10.

[0053] In this embodiment, a main switch 30, a charging port 31, and multiple power sockets 32 are provided on the back plate 3. The main switch 30, the charging port 31, and the power sockets 32 are all electrically connected to the control circuit board 41.

[0054] In this embodiment, an operation panel 43 is provided on the frame 2, and the operation panel 43 is electrically connected to the control circuit board 41.

[0055] In this embodiment, a foot 12 is provided at the bottom of the housing 1, and a handle is provided at the top of the housing 1.

[0056] Since the main switch 30, charging port 31, multiple power sockets 32, control panel 43, foot pad 12 and handle are all existing technologies and not the focus of this embodiment, they are not described in detail in this embodiment.

[0057] The dustproof and moisture-proof UPS provided by this utility model allows for the opening of the flap 61 by the flip drive 60 when heat dissipation is required, allowing external airflow to enter. The airflow passes sequentially through the dustproof grille 55 and the dehumidifier block 52. The dustproof grille 55 adsorbs dust from the air, and the dehumidifier block 52 adsorbs water vapor from the air. The filtered airflow is then blown into the chamber by the cooling fan 53 to dissipate heat for the electronic components, and then blown out from the exhaust 10. The dustproof grille 55 and the dehumidifier block 52 effectively prevent dust and moisture from entering the chamber and affecting the service life of the electronic components, effectively protecting the UPS.

[0058] Where there is no conflict, the above embodiments and features can be combined with each other.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
