Detailed description of the invention
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples for illustration of the present invention, but can not be used for limiting the scope of the invention.
In describing the invention, it should be noted that, term " " center ", " edge ", " on ", the orientation of the instruction such as D score or position relationship be based on orientation shown in the drawings or position relationship; be only the present invention for convenience of description and simplified characterization; instead of instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.In addition, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance.
Refrigerator wire-tube evaporator 2 of the present invention, the metal coil pipe 21 being included in coiling in plane and the wire 22 be laid on described coil pipe.Wherein, the closeness of described wire 22 on the border area of metal coil pipe 21, the closeness of described wire 22 on the central area being greater than described metal coil pipe 21.Adopt the refrigerating chamber 1 of this wire-tube evaporator 2, its border area heat exchange efficiency is high, refrigerating capacity is strong, effectively can eliminate the shortcoming that refrigerating chamber 1 space ambient temperature is higher, its temperature is made to keep consistent with central area, improve the uniformity of refrigerating chamber 1 space temperature, ensure food storage quality, and reduce the power consumption of product.
In the present embodiment, on preferable alloy coil pipe 21, the closeness of described wire 22 increases progressively from central area toward border area, thus the refrigerating capacity of wire-tube evaporator 2 is increased progressively from central area toward border area, and reach the object improving refrigerating chamber 1 space temperature uniformity further.
Refer to Fig. 2 and Fig. 3, in this figure, metal coil pipe 21 is bent by single piece of metal pipe and forms, and metal tube comprises multistage straight line pipeline section parallel to each other, and for connecting the bending tube section of adjacent described straight line pipeline section.In figure, straight line pipeline section is uniformly distributed thus distance between adjacent straight spool section is all equal.In addition, wire 22 to be welded on described straight line pipeline section and vertical with straight line pipeline section.
It should be noted that the metal coil pipe 21 of the present embodiment and wire 22 by the restriction of accompanying drawing, it can be adopt any known form in prior art.
In the present embodiment, metal coil pipe 21 can be steel pipe, copper pipe or aluminum pipe.Preferable alloy dish is steel pipe, and correspondence, wire 22 is chosen as steel wire, thus makes wire-tube evaporator 2 have better heat conduction refrigeration on the basis ensureing manufacturing cost.
In order to improve the refrigerating capacity of wire-tube evaporator 2 under the prerequisite ensureing refrigerating chamber 1 space temperature uniformity, the wire 22 of the present embodiment is distributed in the both sides up and down of described coil pipe, and forms 22 layers, the first wire and 22 layers, the second wire.Both sides due to metal coil pipe 21 are respectively arranged with one metal wire layer 22, thus when metal coil pipe 21 surface area is certain, increase the heat transfer area of wire-tube evaporator 2, make wire-tube evaporator 2 and air exchange more abundant, and then further increase the refrigerating capacity of the refrigerator being provided with this wire-tube evaporator 2, and reduce the energy consumption of refrigerator.
It is worth mentioning that, existing wire-tube evaporator 2 adopts the method for coating of dusting to realize antiseptic effect, but the thickness being sprayed on the powder bed on metal coil pipe 21 and wire 22 reaches 0.5mm, and the heat conductivility of powder bed is very poor, thus has had a strong impact on the heat-transfer effect of wire-tube evaporator 2.Electrodeposited coating is adopted to replace powder bed in the present embodiment.Particularly, coil pipe is provided with the first electrodeposited coating, wire 22 is provided with the second electrodeposited coating.Wherein, electrodeposited coating not only has antiseptic effect, and has good heat conductivility.Thus, the cold of metal coil pipe 21 inside effectively outwards can be passed to by the first electrodeposited coating and the second electrodeposited coating, and then ensures the refrigeration of wire-tube evaporator 2.
Wherein, the first electrodeposited coating and the second electrodeposited coating can adopt different plating materials according to specific needs.Further, because the electrodeposited coating of unlike material often has different colours, thus can decorate freezer compartment of refrigerator 1, make refrigerating chamber 1 have better visual effect.
In addition, due to wire-tube evaporator 2 very easily frosting in process of refrigerastion, and frost is unfavorable for heat conduction.Thus, in order to reduce the frost be attached on wire-tube evaporator 2, preferably on the first electrodeposited coating, be provided with the first hydrophobic layer, the second electrodeposited coating is provided with the second hydrophobic layer.By the setting of above-mentioned hydrophobic layer, wire-tube evaporator 2 surface not easily solidifying water can be made, and then prevent the formation of frost.It is emphasized that the existence of frost also can affect refrigerator inside to the visual experience of people, therefore arranging of above-mentioned hydrophobic layer can also reach aesthetic.
Wherein, the first hydrophobic layer and the second hydrophobic layer material can but must not select curable liquid resin.
Above embodiment is only for illustration of the present invention, but not limitation of the present invention.Although with reference to embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, various combination, amendment or equivalent replacement are carried out to technical scheme of the present invention, do not depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
