Normal temperature moisture separator for electrical cubicle

Abstract

The normal temperature moisture separator of regulator cubicle provides good dehumidifying effect at normal temperature. The moisture separator includes shell body, air inlet, air outlet, fan blower, heater, moisture absorption element, and mechanism for controlling inlet air and outlet air. The shell body includes front cover, back cover, and protect shield cover. The front cover and the back cover are connected fixedly, and the back cover and the protect shield cover are also connected fixedly. The front cover is positioned inside the cubicle. The back cover and protect shield cover are positioned outside the cubicle. The said controlling mechanism is located between the front cover and the back cover. Fan blower is positioned between the back cover and the protect shield cover. Air inlet and air outlet are located at faceplate of the front cover, and floor plate of the back cover. Air outlet is at end part of the protect shield cover.

Description

technical field [0001] The invention relates to a normal temperature dehumidifier for an electric cabinet. Background technique [0002] There are two main dehumidification methods in the existing fully enclosed electrical cabinets: one is to use heating to dehumidify, that is, to use an electric heater to heat the air in the electrical cabinet, because the air temperature in the electrical cabinet increases and the saturated humidity increases, so the relative humidity However, since the electrical cabinet is closed, the moisture cannot be discharged, so the absolute humidity does not change, and the electrical cabinet actually becomes a high-temperature and high-humidity environment, which is not good for the operation of electrical components; the other is to use refrigeration and dehumidification, which will The evaporator is installed in the electrical cabinet, and when the refrigerant evaporates, it absorbs heat, reduces the temperature in t...

[0002] There are two main dehumidification methods in the existing fully enclosed electrical cabinets: one is to use heating to dehumidify, that is, to use an electric heater to heat the air in the electrical cabinet, because the air temperature in the electrical cabinet increases and the saturated humidity increases, so the relative humidity However, since the electrical cabinet is closed, the moisture cannot be discharged, so the absolute humidity does not change, and the electrical cabinet actually becomes a high-temperature and high-humidity environment, which is not good for the operation of electrical components; the other is to use refrigeration and dehumidification, which will The evaporator is installed in the electrical cabinet, and when the refrigerant evaporates, it absorbs heat, reduces the temperature in the electrical cabinet, and reduces the saturated humidity, so that the moisture in the air in the electrical cabinet is condensed and precipitated, and the condensed water is discharged out of the cabinet through the condensation pipe In addition, however, when the outdoor temperature is low, especially in the northern winter, the condensed water will freeze, resulting in the failure of dehumidification

[0003] Therefore, the existing technology has the following disadvantages: it can only operate at high or low temperature, and cannot dehumidify at room temperature, and the dehumidification effect is poor
