Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, in particular to an industrial dehumidifier. Background Art

[0002] Dehumidifiers are also called dehumidifiers and dryers. They can be generally divided into two categories: civil dehumidifiers and industrial dehumidifiers. They are a member of the air-conditioning family. Usually, a conventional dehumidifier consists of a compressor, a heat exchanger, a fan, a water container, a casing and a controller. Its working principle is that the fan draws humid air into the machine, passes through the heat exchanger, and the water molecules in the air condense into water droplets. The treated dry air is discharged from the machine. This cycle keeps the room dry.

[0003] The working environment of industrial dehumidifiers is relatively harsh, with more dust, and higher requirements for filtration and regular cleaning of equipment. However, existing dehumidifiers generally have filters installed at the air inlet for filtration, which require regular shutdown for cleaning or replacement. In addition, the heat exchanger is generally fixed in the chassis by bolts, and the heat exchanger is connected to the compressor by a hose or metal pipe. There is refrigerant inside, which is not convenient to disassemble and clean. If maintenance is not timely, it will cause problems such as poor heat dissipation and shortened service life.
