Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
Specific embodiment is as shown in figures 1 and 3, and parallel-flow evaporator includes inflation plate 4, is printed with not on the inflation plate
Microchannel tubing 1 greater than 1mm, and rolling inflation is carried out, the passage tube hydraulic diameter after inflation is not more than 1mm, and inflation
At least two layers of microchannel tubing plate afterwards, on the micro-channel tubes road in inflation unit volume entrance and exit confluence after and with
2 phase of interface on the inflation plate end is converged, and the interface of inflation plate end is connected with connecting tube 6, the connecting tube with
Piping connection on refrigerator or refrigerator-freezer.
Microchannel tubing inflation plate after the inflation is parallel or bending, bending be by the flex area 3 of inflation plate into
Row is converted into U-shaped, S type or W type, and fin 5 is fixed between two layers of inflation plate after bending, and fixed form can be crimping and fix,
Certainly rivet or weld, which can also be used, fixes (as shown in Figure 5).
The inflation plate selects two-sided inflation, the two-sided inflation of single-side blowing-up or part single side part.
It is entirely micro-channel tubes of the hydraulic diameter no more than 1mm that the pipeline of micro-channel tubes road after the inflation, which is selected,
Road, or selection part is microchannel tubing or part is conventional conduit.
The parallel-flow evaporator and its manufacturing method that use on refrigerator/freezer are through the following steps that realize: in plate
On required according to the pipeline of refrigeration for refrigerator, be printed as no more than the required amount of microchannel tubing of 1mm, then inflation hot rolling obtains
Inflation plate hydraulic diameter is not more than 1mm inflation plate.The inflation plate with microchannel tubing is bent into finally by bending technique
Required shape, such as U-shaped, S type, W type, can not also bending, direct flat plate use.
The pipeline of the utility model is not more than the microchannel tubing of 1mm using hydraulic diameter, since the size of small pipeline is imitated
It answers, so that convection transfer rate increases, can play and improve heat exchanger effectiveness as parallel flow heat exchanger in the prior art
Effect；It, can be according to refrigerator or refrigerator-freezer not again since its all pipeline is to roll inflation after printing by plate to form
Same pipeline shape and structure requires to be printed, and can also carry out bending according to the requirement of structure, and do not need in pipeline
Between increase solder joint, the processing is simple, and heat transfer efficiency is high.
Further, the inflation plate can be two layers of aluminum plate hot rolling, then be blown into the pipeline of single layer；It can also be by three
The aluminum plate hot rolling of layer or more, is then blown into the inflation plate being superimposed with two or more layers microchannel tubing.
Can there are more heat exchange microchannels, further raising heat exchanger effectiveness in unit volume in this way.
Further, there is the inflation plate of microchannel tubing can be plate can also be with bending, for example, U can be converted into
Type is curved, S type is curved, W type is curved or other shapes, to reduce the volume of evaporator, in the condition for not increasing refrigerator or refrigerator-freezer total volume
The lower internal volume for improving refrigerator or refrigerator-freezer.
Further, when inflation plate uses bending shape, rivet, weld between two layers of inflation plate of two bendings,
Crimp fin；
Has the inflation plate micro-channel parallel flow evaporator of above structure, the presence for being not only due to microchannel to quickly complete
The heat exchange of refrigerant and evaporator body, and due to the presence of fin, increase the cooling surface area of evaporator body, energy
The heat exchange of evaporator body and refrigerator or refrigerator-freezer internal environment is quickly completed, so as to avoid evaporator surface and refrigerator or ice
Circumstance of temperature difference frosting caused greatly, improves refrigerator or refrigerator-freezer entirety heat exchanger effectiveness in cabinet.
Certainly, evaporator obtained above needs as needed, then welds aluminium adapter tube or copper-aluminium joint, to facilitate and ice
The connection of case or the other pipelines of refrigerator-freezer.
Microtubule due to pipeline using hydraulic diameter no more than 1mm, the dimensional effect of small pipeline make heat convection
Coefficient increases, and improves heat exchanger effectiveness.It can require to carry out according to the different pipeline shape and structure of refrigerator or refrigerator-freezer again simultaneously
Inflation is rolled after printing to form, and does not need to weld among pipeline, the processing is simple.
Inflation plate micro-channel parallel flow evaporator with this structure, the presence for being not only due to minim channel make rapidly
The heat exchange of refrigerant and evaporator body is completed, and due to the presence of fin 5, increases the heat-delivery surface of evaporator body
Product can quickly complete the heat exchange of evaporator body and refrigerator or refrigerator-freezer internal environment, so as to avoid evaporator surface and ice
Circumstance of temperature difference frosting caused greatly, improves refrigerator or refrigerator-freezer entirety heat exchanger effectiveness in case or refrigerator-freezer.
In the utility model unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " fixation "
Equal terms shall be understood in a broad sense, for example, it may be fixedly connected, may be a detachable connection or integrally connected, can be two
Connection inside a element.For those skilled in the art, above-mentioned term can be understood in this reality as the case may be
With novel concrete meaning.
