A semiconductor dehumidifier

Abstract

The invention discloses a semiconductor dehumidification device. The device comprises a cold-side radiator, a semiconductor refrigeration sheet, a partition plate, a water tank, a fan, a hot-side radiator and a shell; the partition plate dives the shell from a horizontal direction into a condensation zone and a heat dissipation zone; and the condensation zone and the heat dissipation zone are communicated with each other through ventilation holes formed in the partition plate; an air inlet located in the condensation zone is formed in the upper part of the shell; an air outlet located in the heat dissipation zone is formed in the top of the shell; the semiconductor refrigeration sheet is arranged in the partition plate; the cold end of the semiconductor refrigeration sheet is connected with the cold-end radiator; the hot end of the semiconductor refrigeration sheet is connected with the hot-end radiator; the cold-end radiator and the hot-end radiator are fixed at two sides of the partition plate; the fan is located between the upper part of the hot-end radiator and the air outlet; the water tank is disposed below the cold-end radiator; and an atomization and water draining device is disposed in the water tank. With the semiconductor dehumidification device of the invention, the technical problems of low dehumidification efficiency, complicated structure and difficulty in waterdrainage of an existing semiconductor dehumidification device can be solved. The semiconductor dehumidification device of the invention has the advantages of high dehumidification efficiency and simple structure, and can realize intelligent water drainage.

Description

technical field [0001] The invention relates to the field of dehumidification equipment, in particular to a semiconductor dehumidification device for frequency converters used in humid and hot environments such as ships. Background technique [0002] The long-term operation of IGBTs, capacitors, and reactors in marine inverters will generate a lot of heat, and the air humidity inside the ship is relatively high. High humidity is one of the most important factors that cause power electronic devices to fail. When the ambient temperature changes, condensation may occur in the inverter, causing short circuits in components such as circuit boards and terminal blocks, and endangering the safe operation of the equipment. The existing semiconductor dehumidification devices for ships are mainly based on the installation of heaters, which use heating sheets to heat the air in the cabinet, and install heaters to increase the temperature in the cabinet and reduce the relative humidity i...
