Description

Technical Field

[0001] This application relates to the field of inverter drying technology, specifically to a drying device for an inverter. Background Technology

[0002] An inverter is a converter that transforms direct current (DC) power into alternating current (AC) power of fixed frequency and voltage or variable frequency and voltage. It consists of an inverter bridge, control logic, and filter circuits. In this "mobile" era, with its mobile offices, mobile communications, and mobile leisure and entertainment, not only is low-voltage DC power supplied by batteries required, but also the indispensable 220V AC power of everyday life. Inverters can meet these needs. Due to the special environment in which inverters are used, a drying device needs to be installed on the outside of the inverter to prevent moisture in the air from easily penetrating the interior and damaging the internal electrical components.

[0003] Patent CN221009996U discloses a drying device for an inverter. This device features mounting cavities on both sides of the inverter chassis, with a drying cylinder inside each cavity. Air passes through the drying cylinder before entering the inverter chassis, where the extended contact time between the air and the desiccant enhances the removal of moisture, ensuring a dry interior and solving the moisture removal problem in existing technologies. The concealed design protects the drying cylinder, and opening and closing the cavity cover facilitates its removal and securing, making replacement and installation convenient. While maintaining dryness within the inverter chassis, the device also provides some heat dissipation, making it user-friendly. However, the inverter in this device is not constantly running. When the inverter stops operating, the cooling fan also stops, allowing external air to enter the inverter through the exhaust vent. This open environment reduces the effectiveness of the drying components, while continuous operation of the cooling fan increases the inverter's operating costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a drying device for an inverter, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: a drying device for an inverter, comprising an outer casing, a drying mechanism for maintaining the humidity inside the outer casing, and a heat dissipation mechanism for preventing excessively high temperatures inside the outer casing. The right side of the outer casing is provided with a sealing mechanism to prevent external warm and humid gases from entering the outer casing when the inverter is not in use. The sealing mechanism includes a baffle and a silicone plate. The baffle is positioned in front of the heat dissipation mechanism, and the side of the silicone plate is fixedly connected to the side of the baffle. The drying mechanism is positioned on the left side of the outer casing, and the bottom of the heat dissipation mechanism is fixedly connected to the bottom of the inner wall of the outer casing.

[0008] By adopting the above technical solution, the silicone plate connected to the baffle can be used to fit the air outlet, thus preventing external moisture-containing gas from entering the outer casing when the inverter is not running.

[0009] Preferably, the sealing mechanism further includes a movable cavity and an electric push rod. The movable cavity is located on the right side of the outer casing, and the electric push rod is fixedly connected to the front side of the movable cavity. One end of the electric push rod is fixedly connected to the front side of the baffle.

[0010] By adopting the above technical solution, the movable cavity can be used to provide space for the movement of the baffle, and the extension and retraction of the electric actuator can be used to provide power support for the movement of the baffle.

[0011] Preferably, the drying mechanism includes an air inlet and a drying box containing a desiccant. The air inlet is located on the left side of the outer casing, and a placement groove is provided at the bottom of the air inlet. The drying box is located inside the placement groove, and a rubber plate is fixedly connected to the side of the drying box. The side of the rubber plate is in contact with the inner wall of the placement groove.

[0012] By adopting the above technical solution, the air outlet can facilitate the entry of external gas, and the drying box placed in the placement slot can absorb the moisture in the gas. At the same time, the fit between the rubber plate and the placement slot prevents the entry of undried gas into the outer casing.

[0013] Preferably, the drying mechanism further includes a telescopic groove and a retaining rod. The telescopic groove is located on the upper left side of the outer box, and a retaining hole is provided on the right side of the telescopic groove and the upper left side of the drying box. The retaining rod is slidably connected to the retaining hole.

[0014] By adopting the above technical solution, the position of the drying box can be fixed by utilizing the sliding connection between the fixing hole on the right side of the telescopic groove and the fixing rod, thereby improving the convenience of replacing the drying box.

[0015] Preferably, the drying mechanism further includes a retaining spring and a control plate. The right side of the retaining spring is fixedly connected to the right side of the inner wall of the telescopic groove. The retaining spring is disposed on the outside of the retaining rod. The control plate is fixedly connected to one end of the retaining rod. The right side of the control plate is fixedly connected to the left side of the retaining spring.

[0016] By adopting the above technical solution, the position of the retaining rod connected to the control board can be fixed by the retaining spring, preventing the retaining plate from shifting due to external collisions and ensuring the stability of the drying box.

[0017] Preferably, the heat dissipation mechanism includes a damping column and an inverter body. The bottom of the damping column is fixedly connected to the bottom of the inner wall of the outer casing, the bottom of the inverter body is fixedly connected to the top of the damping column, a shock-absorbing spring is fixedly connected to the bottom of the inverter body, the bottom of the shock-absorbing spring is fixedly connected to the bottom of the inner wall of the outer casing, and the shock-absorbing spring is disposed on the outside of the damping column.

[0018] By adopting the above technical solution, the possibility of vibration being transmitted to the inverter body can be reduced by using damping columns and shock-absorbing springs, thus ensuring the stability of the inverter body.

[0019] Preferably, the heat dissipation mechanism further includes an air outlet and a fan. The air outlet is located on the left and right sides of the movable cavity, and the fan is fixedly connected to the left side of the inner wall of the air outlet.

[0020] By adopting the above technical solution, the fan in the air outlet can drive the circulation of gas inside the outer casing and the outside air, thereby achieving the purpose of reducing the temperature inside the outer casing and dissipating heat.

[0021] Preferably, the heat dissipation mechanism further includes a heat sink and a dustproof plate, wherein the heat sink is fixedly connected to the surface of the inverter body, and the side of the dustproof plate is fixedly connected to the right side of the inner wall of the air outlet.

[0022] By adopting the above technical solution, the heat generated by the inverter body can be dissipated using heat sinks, thus accelerating the heat dissipation process. Furthermore, dustproof plates can be used to prevent dust and other contaminants from entering the outer casing and damaging the inverter.

[0023] (III) Beneficial Effects

[0024] This application provides a drying device for an inverter, which has the following beneficial effects:

[0025] 1. The drying device of this inverter, by setting a closed mechanism, the electric push rod in the active chamber extends and drives the baffle to move backward. The baffle moves until the silicone plate is in contact with the air outlet, which prevents the external undried gas from entering the outer box. This prevents the open environment from reducing the drying box's effectiveness, reduces the inverter's operating cost, extends the inverter's service life, and improves the cost-effectiveness of the drying device.

[0026] 2. The inverter's drying device, through the setting of a heat dissipation mechanism, damping columns and shock-absorbing springs reduce the upward transmission of vibrations, heat sinks conduct heat generated by the inverter body during operation, and a fan drives the air in the outer casing to carry the heat out through the air outlet connected to the dustproof plate, which shortens the retention time of heat generated by the inverter during operation, reduces the possibility of overheating causing short circuits in the inverter, extends the usable time of the inverter, and reduces the cost of using heat conduction components.
