The invention discloses an internal dehumidification device for a high frequency switching power supply. The device comprises a device body; the device body is composed of a mounting plate and a filler box, the filler box is composed of a shell, a filler chamber, a feeding port and a discharging port, and the filler chamber is formed in the inner side of the filler box; the shell is located at theouter side of the filler chamber, the filler chamber is filled with water absorption filler, and the feeding port is formed in the upper side of the filler box; a feeding port sealing cover is arranged at the upper side of the feeding port, the discharging port is formed in one side of the bottom of the filler box, and a discharging port sealing cover is arranged at one side of the discharging port; an observation window is formed in one end of the filler box and embedded in the upper side of the shell, tempered glass is arranged at the upper side of the observation window, and a partition net is arranged on the portion, located at one side of the mounting plate, of the filler box. According to the internal dehumidification device, air nearby the power supply is dried through the water absorption filler, the water content in the air is reduced, and vapor condensation is reduced during hot and cold alternation.
Description
technical field [0001] The invention relates to the technical field of electric power accessories, in particular to an internal dehumidification device for a high-frequency switching power supply. Background technique [0002] Power supply is an indispensable part of various electronic equipment, and its performance is directly related to the technical indicators of electronic equipment and whether it can work safely and reliably. Since the key components inside the high-frequency switching power supply work in the high-frequency switching state, the power consumption is small, the conversion rate is high, and the volume and weight are only 20% to 30% of the linear power supply, so it has become the mainstream product of the regulated power supply at present. It has a very wide range of applications in the industrial field. When the power supply is in use, it is generally in direct contact with the air. When the weather is humid, there will be a lot of steam surrounding the ...
