Abstract
The present invention relates to the field of an air conditioner, particularly to a manufacturing method of fins of an air conditioner heat exchanger and the air conditioner heat exchanger. The present invention has the manufacturing method that a nanometer phhotocatalyst colloidal sol is used for dipping and coating the aluminum fins of the heat exchanger, the fins are dried and baked to form a macroscopic, continuous and firm nanometer inorganic oxide film layer, and the aluminum fins are manufactured into the air conditioner heat exchanger according to a normal mode. The hydrophile performance of the fins reaches or exceeds the performance of an organic precoating aluminum foil. Water can not form water drops on an aluminum sheet, and completely spreads on the surface of the aluminum sheet to form a uniform water film. Therefore, a water bridge can not be generated, heat exchange quantity and heat exchange speed rate between the aluminum foil and the flowing air are improved. Because the film layer of the surface of the aluminum foil of the heat exchanger is a high activity photocatalyst, air flowing through the heat exchanger can be purified, and formaldehyde, benzene, oil fume and other organic harmful gases in the air are oxidized and decomposed into harmless water and harmless carbon dioxide.
Description
Technical field
The present invention relates to the conditioner field, be specifically related to a kind ofly, the invention still further relates to a kind of air-condition heat exchanger that adopts above-mentioned fin to make by obtaining having the fin of Superhydrophilic and photocatalysis Decomposition obnoxious flavour after the surface of fin in the air-condition heat exchanger is handled.
Background technology
In the prior art, small-sized, multi-functional and high energy efficiency is than the developing direction that is domestic air conditioner.Interchanger is one of core component of conditioner, and its heat exchange performance directly influences the serviceability of conditioner.Air-condition heat exchanger is made of with the parallel aluminous fin that is through on this copper pipe copper pipe.The heat transfer process of conditioner comprises two heat exchange steps between refrigerant and interchanger, interchanger and the fluidizing air.Heat exchange between refrigerant and the interchanger is finished by copper pipe, and the heat exchange between interchanger and the fluidizing air is finished by aluminous fin.Last process generally adopts inner screw thread copper pipe to increase heat interchanging area raising heat-exchange capacity; The back one process relative complex some, reduce spacing of fin increase number of fins and help increasing heat interchanging area, improve heat exchange efficiency, but when spacing of fin reduces, water of condensation can be because wicking action forms " water bridge " between fin, this not only can make the windage of conditioner and noise increase, but also can make air-conditioning " blowing water " phenomenon occur, and the people is done not feel like oneself.In order to solve this a pair of contradiction, conditioner manufacturer now extensively adopts the aluminium foil of precoating hydrophilic layer to make interchanger, but because this class hydrophilic film mostly is high molecular polymer, heat conductivility is bad, and the result is that wetting ability has improved, and thermal conductivity has but descended.Obviously, adopt the aluminium foil of organic precoated hydrophilic film can not farthest improve the heat exchange efficiency of interchanger.
Another development trend of domestic air conditioning is to realize multifunction.Conditioner uses in closed environment, and indoor air is more and more dirty, causes the people to produce uncomfortable sensation, and promptly so-called " air conditioning disease " has a strong impact on the healthy of people.In order to address this problem, a lot of manufacturers are provided with the filtering net that adopts various sorbent materials to make on the wind path of conditioner, adsorb and remove harmful substances in air.Though this method has the improvement of certain effect to air quality because the restriction of loading capacity, exist adsorptive capacity little, saturated, the problem such as can't regenerate of absorption is arranged, and make the adsorbed contaminants desorption easily, cause secondary pollution.
