Abstract

The utility model discloses a refrigerator cold room equipped with a surface-mounted evaporator, comprising a cold room and an evaporator, wherein the evaporator is arranged at the inner surface of the cold room in a surface-mounted way, so that the evaporator can directly conduct heat exchange with air in the cold room, and temperature reduction speed in the cold room can be accelerated, thus effectively saving energy consumption; the evaporator is formed by continuous U-shaped pipes which are normally U-shaped aluminium pipes, and simultaneously, a metal wire or a metal layer is paved on the surface of the evaporator, thus effectively enlarging the heat exchange area; a cladding layer is arranged on the surface of the U-shaped aluminium pipe of the evaporator, thus avoiding contact of the aluminium pipe with condensed water, retarding the oxidation rate of the U-shaped aluminium pipe, and further greatly prolonging the service life of the refrigerator; as the evaporator is arranged on the inner surface of the cold room in a surface-mounted way, when leakage fault occurs to the refrigerator, leakage detection can be quickly conducted on the evaporator, the evaporator can be replaced very conveniently, and the whole appearance and the use effect can not be influenced.

Description

A kind of cold compartment of refrigerator of being furnished with bright dress evaporimeter

Technical field

The utility model relates to the refrigerator technical field, relates in particular to a kind of cold compartment of refrigerator of being furnished with bright dress evaporimeter.

Background technology

Have rime ice case refrigerator evaporator all to be contained in the refrigerator interlayer now, promptly plastics inner bag outside is near the plastics inner bag, and from the consideration of practicing thrift cost, evaporator of refrigerator all adopts aluminium matter pipeline to make and is not wire or the metallic plate that strengthens cold and hot exchange area.

The shortcoming of previous design aspect energy consumption shows: (1) passes cold difficulty because evaporator pipeline (circumference) appearance major part is wrapped in the insulating foam material to refrigerating chamber; (2) because evaporimeter generally all is in low-temperature condition, reside in steam in the insulation material and meet cold meeting and around evaporator pipeline, tie water, because foamed material is very close,, be difficult for flowing away around being trapped among pipeline because of the water that the capillarity principle is formed always.Refrigerator inside will be freezed and must be lowered the temperature of this part water of tying in the foam around the evaporator pipeline earlier, and refrigerator inside just can cool down then; (3) in the heat-insulation layer water is arranged after, reduced heat insulation effect, outside heat is easier to import into refrigerator inside; (4) inner container of icebox generally all is made of plastic, and cold transmits poor-performing to refrigerating chamber, makes energy consumption increase.Refrigerator service life has also been shortened in original design to a certain extent, because the aluminum pipe long period of soaking is easy to oxidation in water, perforation causes the leakage of cold-producing medium at last then.

Also there is shortcoming in previous design aspect repairing, show: (1) need be transported to repair shop to refrigerator and repair if refrigeration system breaks down, and there is traffic expense twice in repair cost; (2) the leak detection time long because pipeline is in interlayer, leak detection can only be adopted the pressurize mode, needs 24 hours usually; (3) maintenance is complicated, after confirming leakage, if amending the law of emphasis outward appearance is to pry open refrigerator back, digs up the insulation material in the interlayer, changes evaporimeter, foams, restores shell again.Because foaming the time does not have special mould, interlayer foaming packing can not get ensureing that heat insulation effect descends and causes energy consumption to increase, and also has the refrigerator cold to reach the possibility of knot water after the appearance.Generally can only the recopper pipe evaporator during repairing, such maintenance penalty is bigger.Also can adopt partial cut to open back, excavate insulation material, weld copper pipe again, bright being layered in the refrigerating chamber, but that this repair method has a strong impact on is attractive in appearance, and exist and newly change the cold and hot exchange area of evaporimeter defective less than normal.

The utility model content

In order to solve the problem of above-mentioned existence, the purpose of the utility model is to provide a kind of energy consumption, long service life and cold compartment of refrigerator of being furnished with bright dress evaporimeter easy to maintenance saved.

To achieve these goals, the utility model adopts following technical scheme:

A kind of cold compartment of refrigerator of being furnished with bright dress evaporimeter comprises refrigerating chamber and evaporimeter, the bright inner surface that is loaded on refrigerating chamber of wherein said evaporimeter.

Preferably, said evaporimeter is made up of continuous U-shaped pipeline, and the flexible distortion of certain-length is left at U-shaped pipeline two ends, and U-shaped pipeline two ends are left certain-length for exporting and inlet in outlet and porch, guarantees to produce, has when keeping in repair certain operating space.

Preferably, the surface of said U-shaped pipeline is provided with covering.

Preferably, said evaporimeter is connected with other pipelines through the mode of welding, is provided with 15-20 centimetre of copper pipe at nearly pad place, the weld job when guaranteeing to change evaporimeter.

Preferably, the surface of said evaporimeter is covered with wire.

Preferably, the surface of said evaporimeter is pasted with metal level.

The utility model has the advantages that: the bright inner surface that is loaded on refrigerating chamber of evaporimeter, like this evaporimeter just can be directly and refrigerating chamber in air carry out heat exchange, can accelerate the cooling rate in the refrigerating chamber; Thereby can save energy consumption effectively, evaporimeter is made up of continuous U-shaped pipeline, and the U-shaped pipeline is generally the U-shaped aluminum pipe; Lay wire or attach metal level on the surface of evaporimeter simultaneously, can effectively strengthen the area of heat exchange, the while is provided with covering on the surface of the U-shaped aluminum pipe of evaporimeter; Can avoid the U-shaped aluminum pipe to contact, slow down the oxidation rate of U-shaped aluminum pipe, thereby prolong refrigerator service life greatly with condensed water; The bright inner surface that is contained in refrigerating chamber of evaporimeter; In the time of refrigerator generation leakage failure, can adopt the method for soapsuds leak detection, rapidly evaporimeter is hunted leak; And can change easily, can not have influence on the whole outward appearance and the effect of use.
