Abstract
The invention discloses a roll-bond silent evaporator which comprises an evaporation plate and a refrigerating pipeline, wherein the refrigerating pipeline is arranged on the evaporation plate and formed in a roll-bond type. The silent evaporator is characterized in that the refrigerating pipeline is divided into a liquid return area and a two-pass pipeline, wherein the two-pass pipeline is formed by serially connecting two groups or more than two groups of evaporation pipelines which are respectively formed by two parallel pipelines; and refrigerant enters the two-pass pipeline, and leaves off the evaporator through the liquid return area. The invention solves the problem that the roll-bond evaporator of the prior art has large refrigerant flowing sound and large integral noise, and achieves the effects of reasonably controlling the flowing rate of the refrigerant and decreasing the flowing noise of the refrigerant by the pipeline design of the roll-bond evaporator.
Description
Technical field
The present invention relates to household electrical appliances refrigeration system component technical fields such as refrigerator, wine cabinet, particularly relate to a kind of roll-bond silent evaporator.
Background technology
The evaporimeter of refrigerating appliances such as traditional refrigerator, refrigerator, wine cabinet mainly contains finned evaporator, tube-in-sheet evaporator and inflation type evaporimeter.Finned evaporator is more common in the wind cooling refrigerator, its main deficiency be volume big, take up space, reduced the dischargeable capacity of refrigerator, and there is the big shortcoming of frosting degree usually in finned evaporator, usually need evaporimeter regularly to be heated defrosting, less employing in small refrigeration systems at present.The tube-sheet type evaporimeter is many to be used on direct cooling refrigerator, as be attached on the back of box liner with case in the air heat exchange, its shortcoming is not attractive in appearance, so many uses are in cabinets cavity.The inflation type evaporimeter is the evaporimeter that adopts double-deck aluminium sheet to be composited, after normally the surface of aluminum plate of certain specification being handled, on the aluminium sheet involutory surface, stamp the pattern of evaporation tubes, composite panel is welded according to pattern, after Technologies for Heating Processing such as hot rolling, carry out inflation with nitrogen at last.The inflation type evaporimeter is common on small-sized refrigerating box, the wine cabinet.At present, the inflation type evaporimeter that uses in the refrigeration industry, the big problem of ubiquity refrigeration noise, cold-producing medium flows in the inflation pipeline, often sends the sound of flow of refrigerant spine, big multi-user is very discontented to this, for the user who refrigerator is placed on the bedroom, its problem to noise is responsive more, sounds because cold-producing medium flows in pipeline, the user in use often complains noise problem to enterprise, and noise brings great discomfort to user's life.
Summary of the invention
The present invention is intended to solve the mobile higher big problem of complete machine noise that causes of noise of inflation type evaporator refrigerant of the prior art, provides a kind of simple in structure, rational roll-bond silent evaporator of layout, to overcome the deficiencies in the prior art.
The scheme that solves the problems of the technologies described above is such:
A kind of roll-bond silent evaporator, comprise evaporation plate and on the refrigeration pipe that forms by the inflation mode, described refrigeration pipe layout is divided into back liquid zone and double-current Cheng Guanlu, described double-current Cheng Guanlu be by two side by side pipeline be that one group two groups or more evaporation pipeline serial connection forms, cold-producing medium enters double-current Cheng Guanlu and leaves evaporimeter after go back to the liquid zone.
Above-mentioned roll-bond silent evaporator, described two groups or more evaporation pipeline is horizontally disposed.
Above-mentioned roll-bond silent evaporator, the serial connection place of described every group of evaporation pipeline is provided with the approximate back-shaped cold-producing medium mouth that crosses.
Above-mentioned roll-bond silent evaporator, described time the liquid zone is located at double-current Cheng Guanlu top.
Above-mentioned roll-bond silent evaporator, described time the liquid zone is provided with the pipeline that multiway intersection converges mutually.
The present invention compared with prior art has the following advantages and beneficial effect:
1) the technical program is rationally controlled the flow velocity of cold-producing medium by the circuit design of inflation evaporimeter, has reduced the mobile noise of cold-producing medium.
2) double-current Cheng Guanlu can make full use of the area of evaporimeter, significantly improves the heat exchange effect, and high refrigeration is renderd a service, and makes refrigerator more energy-conservation.
3) technology is made convenient simpler than existing inflation type evaporator pipeline.
Description of drawings
Fig. 1 is an inflation type evaporation structure schematic diagram of the present invention.
The specific embodiment
Among Fig. 1, each label is represented:
4 times liquid zones of 1 evaporation plate 2 capillaries, 3 double-current Cheng Guanlu
The present invention reduces noise, effectively utilizes disengagement area to improve evaporability by the structure that changes refrigerant tubing, makes refrigerator more energy-conservation.Referring to Fig. 1, roll-bond silent evaporator of the present invention is made of evaporation plate 1 and evaporation pipeline, and layout roughly is go back to liquid zone 4, parallel pipeline district from top to bottom.Evaporation plate 1 connects the muffler and the capillary of opposite course each other, walk a segment distance under the single tube road direction of connection capillary 2, enter double-current Cheng Guanlu 3 after crossing go back to liquid zone 4, double fluid Cheng Guanlu 3 be with two side by side pipeline be one group many groups of horizontally disposed evaporation pipelines side by side: after coming out from the single tube that erects away, cross after two arranged side by side horizontal branches are laterally walked to the left from the right side of evaporation plate earlier, be divided into again to two parallel branch arranged side by side and enter down one deck pipeline, cross after laterally walking to the right from the left side of evaporation plate.Treat away to the evaporation pipeline arranged side by side of the bottom, upwards to enter go back to the liquid zone, leave evaporimeter from going back to the liquid zone.
The pipeline multiway intersection that goes back to liquid zone 4 converges mutually, and this structure reduces flow velocity by the resistance and the cold-producing medium gravity of evaporator pipeline inwall once more; Cold-producing medium return liquid zone 4 flow of refrigerant directions by evaporation plate on to down, again from the bottom to top, enter the return-air part, the pipeline that intersects can better be stored cold-producing medium, at the cold-producing medium that goes back to the liquid zone is flooded type, be equivalent to the reservoir effect, so also the flow velocity to cold-producing medium plays very big control action.
Roll-bond silent evaporator of the present invention mainly is to distribute to double-current Cheng Guanlu equably after entering evaporimeter by the cold-producing medium after capillary-compensated, the step-down, cold-producing medium is flowed in pipeline produce drag losses, the flow velocity of control cold-producing medium in pipe is in rational flow rates, to reduce the sharp-pointed sound that cold-producing medium flows and produced rapidly thereby speed descends.
Simultaneously,, significantly improved the heat exchange effect of cold-producing medium and evaporation plate, obtained the higher heat transfer coefficient and the area of evaporimeter, thereby cut down the consumption of energy owing to used the cloth tubular construction of apportion two-way.
