Countercurrent plate type dew-point indirect evaporative cooler with internal dividing structure, and channel clapboard

Abstract

The invention discloses a countercurrent plate type dew-point indirect evaporative cooler with an internal dividing structure. The cooler comprises a dew-point indirect evaporative cooler core body arranged in a casing, wherein a wind inlet and a secondary air exhaust opening are formed in the top of the casing, and a primary air supply opening is formed in the bottom of the casing; the dew-point indirect evaporative cooler core body is composed of multiple side-by-side dry channels and wet channels spaced in parallel; a clapboard is arranged between each dry channel and the corresponding wet channel; the surfaces of the clapboards, on the dry channels, are hydrophobic surfaces, and the surfaces of the clapboard, on the wet channels, are hydrophilic surfaces; a dividing hole is formed in the lower part of each clapboard, and part of air in the dry channels enters the corresponding wet channels through the dividing holes and runs in the wet channels as secondary air, and primary air and the secondary air flow reversely; meanwhile, each channel clapboard of the cooler core body comprises a plastic base plate; and one surface of each base plate is flocked by adopting an electrostatic flocking process to obtain the clapboard with the hydrophobic surface and the hydrophilic surface, and the thickness of the clapboard is 0.1-0.4mm.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to an improved dew point indirect evaporative cooler in the form of a counterflow plate cooler. Background technique [0002] The indirect evaporative cooler is a new type of air-conditioning refrigeration equipment. It uses the difference between the dry bulb temperature and the wet bulb temperature in the natural ambient air to obtain enthalpy and humidity energy through the heat and moisture exchange between water and air. It is an environmentally friendly, efficient and economical cooling method. Without the use of compressors and refrigerants, the gas can be cooled to close to the wet bulb temperature of the air without increasing the moisture content of the produced air. Fresh air can be used in the evaporative cooling process, and the air quality is good. [0003] As an improvement to indirect evaporative cooling technology, ...

Problems solved by technology

The performance of a single material is single, and it cannot have the condition that one side is hydrophilic and the other side is hydrophobic and the stiffness is sufficient. The composite sheet is affected by the composite process, and the hydrophilic effect is not good, and the thick channel partition is not conducive to heat exchange, so it needs to be replaced. an ideal alternative material
