Brief description of the drawings
Fig. 1 is the schematic cross-section of evaporator of refrigerating device antifrost structure of the present invention.
Specific embodiment
Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
The present invention provides a kind of antifrost structure of evaporator of refrigerating device, evaporimeter frosting for preventing refrigerating plant, Fig. 1 is the schematic cross-section of the antifrost structure, as shown in the figure, the antifrost structure is made up of the hydrophobic film 11 containing polytetrafluoroethylene (PTFE) and Ludox, and the hydrophobic film 11 is formed on the metal surface 12 of evaporator or is pasted onto on the case courage inner surface 12 ' of refrigerating plant.
In one embodiment, above-mentioned refrigerating plant is derect refrigerated refrigerator, and evaporator is wire-and-tube evaporator, then hydrophobic film 11 can be formed on the metal surface 12 of wire-and-tube evaporator by infiltrating treatment and being heating and curing.Specifically, the wire-and-tube evaporator commonly used for derect refrigerated refrigerator, can immerse hydrophober after wire-and-tube evaporator completes " dusting " technique by evaporator（The Water-based Water-repellent of component generally based on polytetrafluoroethylene (PTFE) and Ludox）For a period of time, being heating and curing in the baking oven of uniform temperature after taking-up makes it form fine and close super hydrophobic film in evaporator plate pipe surface.
In one embodiment, above-mentioned refrigerating plant is derect refrigerated refrigerator, and evaporator is adhesive type evaporator, then the Pasting of hydrophobic film 11 is on the interior case courage inner surface 12 ' with above-mentioned adhesive type evaporator.Specifically, for the adhesive type evaporator that direct cooling refrigerator is used, because evaporator is pasted onto inside case courage, hydrophobic effect is not had if directly carrying out hydrophobic treatment in evaporator and forming hydrophobic film, therefore hydrophobic film 11 first can be made with hydrophober, hydrophobic film then is pasted onto into inside is stained with the case courage inner surface 12 ' of evaporator.
In one embodiment, above-mentioned refrigerating plant is air-cooling electric refrigerator, and evaporator is finned evaporator, then hydrophobic film 11 can be formed on the metal surface 12 of finned evaporator by infiltrating treatment and being heating and curing.Specifically, the finned evaporator commonly used for air-cooling electric refrigerator, can immerse hydrophober by the finned evaporator after general assembly, and being then placed in baking oven heating makes the hydrophober of its evaporator coil and fin surface solidify to form hydrophobic film 11.
In one embodiment, above-mentioned refrigerating plant is refrigerator, and evaporator is pipe-coil type evaporator, then the Pasting of hydrophobic film 11 is on the inner bag surface 12 of refrigerator " on.Specifically, for refrigerator, because its evaporator is usually to be affixed directly to inside the metal inner tube of refrigerator using evaporator coil, it is thus similar with the adhesive type evaporator of derect refrigerated refrigerator, may be otherwise and first produce hydrophobic film 11 with hydrophober, be then affixed to freezer liner surface 12 " on.
In one embodiment, the metal surface 12 of above-mentioned evaporator of refrigerating device relative to refrigerating plant inner bag surface into an inclination angle, so that the moisture condensed on hydrophobic film 11 can slide when certain along inclined surface, the frosting of evaporator surface is so further prevented.
Understood in the above, in order to solve traditional easy frosting of refrigerator and refrigerator evaporator surface, and cause the increase of refrigerator power consumption, storage food moisture to be lost in, the problems such as so as to be unfavorable for food fresh-keeping and perishable evaporator, the present invention makes evaporator surface form hydrophobic film using hydrophobic treatment technology（Direct cooling refrigerator or the refrigerator case courage at evaporator paste the hydrophobic film of pre-production）, evaporator surface no longer frosting or frosting degree be considerably less, so as to solve above-mentioned problems.
For body, the hydrophobicity of material is that, due to the effect of hydrophobic group, general hydrophobic group is c h bond, such as oil substances.In other occasion, hydrophobicity is also referred to as wettability, by composite insulator external insulation（Silicon rubber）Surface
Tension force decision, characterizes wetting power of the moisture to composite insulator external insulation.Hydrophober essence is exactly waterproofing agent, simply in name
There is difference in face, and usual waterproofing agent is a kind of auxiliary agent with hydrophobic effect." hydrophobic " broadly refers to product resistance Environmental Water and produces dysgenic ability to its main performance.International " Test method for hydrophobic nature of thermal insulation " " term is fixed
In justice ", it is stipulated that to reflect a performance indications of material resistant to water penetration, after being sprayed through the current of prescribed manner, certain flow
The percentage by volume of not permeable part is represented in sample.Current modified organic silicon class hydrophober is a kind of more general efficient hydrophobic agent of insulation material, its hydrophobic mechanism is using chemical affinity stronger between organo-silicon compound and inorganic silicate material, carry out the effective surface characteristic for changing silicate material, make up to hydrophobic effect, it have good stability, low cost, apply process is simple the features such as.
The Water-based Water-repellent of invention component based on polytetrafluoroethylene (PTFE) and Ludox; hydrophobic film is formed in metal surface; its hydrophobic angle is up to 147 ° to 156 °; it has strong repellency; Environmental Water can effectively be slowed down to threaten the micro-cell corrosion that piece surface is constituted; this film layer can also form good mechanical masking to metal simultaneously, so as to improve the protectiveness to part.
Upper described, the antifrost structure that technical solution of the present invention is provided forms hydrophobic film by the formation directly on a surface in evaporator of refrigerating device or stickup, can effectively prevent evaporimeter frosting such that it is able to reduce energy consumption of refrigerator, and be conducive to food fresh-keeping.More specifically, the antifrost structure for being provided by technical solution of the present invention can bring following beneficial effect.
1. the work of highest heat transfer efficiency, for refrigerator, derect refrigerated refrigerator and air-cooling electric refrigerator, all greatly reduces the electric energy consumed because compressor works long hours；
2. for air-cooling electric refrigerator, it is possible to reduce the time of defrost electrical heating work even cancels defrost electrical heating, on the one hand can reduce energy consumption of refrigerator, on the other hand can also reduce the manufacturing cost of air-cooling electric refrigerator；
3. make to remain steam-laden state in refrigerator or refrigerator case, reduce storage food（Fruits and vegetables etc.）Water loss, be conducive to food fresh-keeping；
4. because evaporator surface forms hydrophobic film（Direct cooling refrigerator or the refrigerator case courage at evaporator paste the hydrophobic film of pre-production）, condensed water is attached to evaporator coil or fin surface, the surface that certain volume can slide and leave evaporator coil or fin reached when having certain angle of inclination or the globule in globule form（Such as the globule on lotus leaf）, reduce the risk of evaporator metal tubing electrochemical corrosion.
It is above preferred forms of the invention, according to present disclosure, one of ordinary skill in the art can be apparent from some identical, alternative solutions, all should fall into the scope of protection of the invention.
