Embodiment
With reference to specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention, after the present invention has been read, various equivalences of the those skilled in the art to the present invention
The modification of form falls within the application appended claims limited range.
A kind of heavy duty detergent double-coil heat-exchanging device disclosed in the embodiment of the present invention, including fin, mutually redundant first heat exchange
Coil pipe and the second heat exchange coil, wherein the first heat exchange coil and the second heat exchange coil include multiple rows of heat exchanging pipe, often row's heat exchange
Pipeline includes multiple U-shaped bending tubes of positive and negative alternate bending, and the first heat exchange coil and the second heat exchange coil are covered with whole fin,
During one of heat exchange coil work, the heat exchange area of wind side can cover whole fin.The pipeline of two heat exchange coils exists
Whole fin is occupied on width, can be arranged at intervals in the height direction.The flow of two heat exchange coils be it is separate, can
Identical or different cooling cycle system is connected to, for refrigerant or refrigerating medium circulation line.If two heat exchange coils are complete
Equity, flow scheme design can be that one of heat exchange coil occupies odd-numbered line heat exchanging pipe, separately by the system for being connected to same low-temperature receiver
One heat exchange coil occupies even number line heat exchanging pipe.In double low-temperature receiver type systems, not reciprocity design can be also used, according to actual conditions
Reasonable adjustment.Corresponding to the holes of two heat exchange coils on fin can also stagger setting in row to (width), be easy to the row in hole
The differentiation of cloth and various heat exchange coil pipe.
The heavy duty detergent double-coil heat-exchanging device of the present embodiment can be used for plate-type exchanger, V-type heat exchanger or the heat exchange of A types
Device, below by taking V-type heat exchanger as shown in Figure 1 as an example, describes the dual coil pipes design cycle and existing design stream of the present invention in detail
The difference of journey and effect.
A kind of heavy duty detergent double-coil heat-exchanging device as shown in Figure 1, mainly by two sets of independent water inlet pipe and water outlet pipe components 4,5, wing
Piece 6, heat exchange coil 3 (the first heat exchange coil and the second heat exchange coil) composition, are protected by tube sheet 1, set square 2, top backplate 7, bottom
Plate 8 is fixed, and forms V-type heat exchanger.Fin 6 and heat exchange coil 3 are used for air and refrigerant (or refrigerating medium), heat exchanger Inlet and outlet water
Tube assembly is connected with the main pipe rail of air-conditioning, for conveying refrigerant (or refrigerating medium).The refrigerant (or refrigerating medium) of low temperature passes through
Water inlet pipe component 5, which enters heat exchanger tube and neutralized, to be flowed through the air of fin 6 and is exchanged heat, and refrigerant (or refrigerating medium) passes through heat exchanger
Heat exchange take away in heat in air, refrigerant (or refrigerating medium) absorption air by heat exchange after heat, become temperature compared with
High refrigerant (or refrigerating medium), is flowed into main frame by outlet pipe component 4, after main frame cools, becomes the system of low temperature
Cryogen (or refrigerating medium), so as to form a set of refrigeration cycle.
Fig. 2 is that the pore on traditional dual coil pipes design flow diagram that above-mentioned V-type heat exchanger is used, fin uses triangular form etc.
Spacing arrangement, such as schemes, and has 8 row, and the first heat exchange coil (being referred to as system A) occupies 1,2,3,4 row of coil pipe, and second changes
Hot coil (being referred to as system B) occupies 5,6,7,8 row of coil pipe, and system A and two coil pipes of system B are separate, and operation is wherein
During one system, another system does not work, and the utilization ratio to whole fin is low.Fig. 3 is the design after present invention improvement
Flow chart, system A occupies 2,4,6,8 row respectively, and system B occupies 1,3,5,7 row, 4 original row fins are exchanged heat respectively
Area increases to 7 row heat exchange areas, has substantially covered whole fin.From structure it can be seen that, no matter runtime A or
Person's runtime B, whole fin can be all participated in heat transfer process, compared with traditional dual coil pipes design, newly-designed stream
Journey scheme can heat exchange efficiency it is higher.Table 1 is tested for the properties of product done under equal size of heat exchanger and heat exchanger tube number
Obtained performance test.
The present invention of table 1 and traditional scheme performance test
From contrast form above, it can be seen that whether the first heat exchange coil or the second heat exchange coil, refrigerating capacity and
Aobvious cold has lifting, and its same air quantity also has lifting.Under equal size of heat exchanger, the exchange capability of heat of present invention heat exchanger will
Exchange capability of heat than traditional heat exchangers lifts 12% or so.Under equal refrigeration capacity requirement, the present invention can reduce heat exchanger chi
Very little, structure design can be compacter.
