Description

Technical Field

[0001] The invention relates to the technical field of direct current screens, and in particular to a condensation-eliminating direct current screen. Background Art

[0002] DC screens are mainly used to supply DC power. During the use of DC screens, due to the temperature difference between the inside and outside, condensation will adhere to both sides of the DC screen, which will easily affect the service life of the DC screen. Therefore, a DC screen needs to be designed.

[0003] The patent application number CN217720332U discloses a moisture-proof DC screen, through which staff can connect the lines through the wire holes, and then interactively control them through the interactive panel. When the DC screen body is used in an environment with relatively humid air, the humid air needs to pass through the filter before entering the DC screen body through the heat dissipation port, and then contact with the desiccant, so that the desiccant can absorb moisture in the air and dehumidify the air, so that the dehumidified air enters the DC screen body through the heat dissipation port. The DC screen absorbs moisture in the air through the desiccant, but the filter is located on the lower side, and condensation will adhere to the left and right sides of the upper part of the DC screen. There is a lack of operation to process the condensation attached to both sides of the DC screen during use.

[0004] We have designed a decondensation DC screen that can handle attached condensation, so as to overcome the problem that the existing DC screen is difficult to handle attached condensation by drying the humid air with a desiccant during use. Summary of the invention
