Specific embodiment
As illustrated in the accompanying drawings from 1 to 3, a kind of coach air conditioner variable flow evaporation core body, including core body side plate 1 and U-shaped heat-transfer pipe 2,
Evaporation core body is fixed on air-conditioner housing by core body side plate 1, and the rim of a cup of U-shaped heat-transfer pipe 2 is towards same direction；U-shaped heat transfer
Pipe 2 is divided into some groups, and per group is a stream, is arranged in parallel between different streams, and the length of evaporation core body bottom stream 9 is big
In the length of top stream 10；Described each bottom stream includes two air inlets or outlet rim of a cup 3 and one goes out liquid or feed liquor cup
Mouthfuls 4, remaining 2 rim of a cup of U-shaped heat-transfer pipe of each bottom stream is connected with three-way elbow 6 by half round elbow 5, air inlet rim of a cup 3 and collection
Trachea component 7 is connected, and is gone out liquid rim of a cup 4 and is connected with dispenser component 8.
For the stream that coolant when heating is passed through, three-way elbow 6 are located at 3/4ths of each bottom stream, that is, work as system
When cold, for the stream that coolant is passed through, three-way elbow 6 is located at a quarter of each bottom stream.
Core body side plate 1 is turnup structure.
Due to distribution and the structure arrangement of air conditioning system of blower fan, the windage at evaporation core body position on the lower is big, heat transfer effect
It is poor, therefore, the pipeline operation length of evaporation core body bottom is changed using three-way elbow so that per coolant flow resistance all the way
Substantially similar, heat transfer effect is consistent as far as possible, lifts the heat exchange amount of whole evaporation core body.
When air-conditioning heating, after gas enters stream, liquid is typically all condensed at 3/4ths of stream, and gas
Body is condensed into volume-diminished after liquid, so three-way elbow 6 is arranged at 3/4ths of each bottom stream, realizes each
The double flow processs entered singly to go out, change bottom stream of bottom stream, the actually uneven face velocity of Proper Match, realization are efficiently changed
Heat.
The course of work of the present utility model is as follows：During refrigerating operaton, through the gas-liquid mixture coolant of expansion valve
Into dispenser component 8, Jing dispenser components 8 are entered in the U-shaped heat-transfer pipe 2 of each point of liquid stream, and gas-liquid mixture coolant exists
Evaporation fan effect is lower constantly to gasify, and becomes gaseous coolant, and Jing collecting pipe components 7 flow out evaporation core body, into compressor air suction
Pipeline.Length of the length of bottom stream 9 more than top stream 10, bottom stream 9 has two liquid outlets, when liquid evaporation is into gas
After body, volume increase, three-way elbow 6 is divided into two branch roads a branch road of stream, realize bottom stream 9 singly enter it is double go out, have
Effect utilizes heat exchange area, reduces the upper and lower temperature difference of evaporation core body.
In heating process, the high-pressure gaseous refrigerant that compressor is discharged enters collecting pipe component 7, and Jing discharges are entered
In each branch line, in the presence of evaporation fan, constantly cooling, liquefaction, becomes the coolant of gas-liquid mixture, Jing liquor separators
Component 8 flows out, and enters into expansion valve.Length of the length of bottom stream 9 more than top stream 10, bottom stream have two gases
Import, after gas is condensed into liquid, three-way elbow 6 is merged into a branch road two branch roads of stream, realizes bottom stream
Double to enter singly to go out, effectively utilizes heat exchange area reduces the upper and lower temperature difference of evaporation core body.
As shown in figure 4, the top view for a bottom stream from terms of rim of a cup direction, including 7 single u-shaped heat-transfer pipes, wherein, a
With the rim of a cup that b is the first U-shaped heat-transfer pipe, c and d is the rim of a cup of the second U-shaped heat-transfer pipe, and e and f is the rim of a cup of the 3rd U-shaped heat-transfer pipe,
G and h are the rim of a cup of the 4th U-shaped heat-transfer pipe, and i and j is the rim of a cup of the 5th U-shaped heat-transfer pipe, and k and l is the cup of the 6th U-shaped heat-transfer pipe
Mouthful, m and n is the rim of a cup of the 7th U-shaped heat-transfer pipe；Rim of a cup b is connected by half round elbow with rim of a cup f, and rim of a cup e and rim of a cup i is by partly

Pipe, after the 5th U-shaped heat-transfer pipe heat exchange, the most of condensation of gas to be condensed becomes liquid, and volume diminishes；Gas to be condensed is from cup
Mouthful d enters the second U-shaped heat-transfer pipe, after being exchanged heat along the second U-shaped heat-transfer pipe, enters the 4th U-shaped heat-transfer pipe from rim of a cup g, along the
After four U-shaped heat-transfer pipes are exchanged heat, the 6th U row heat-transfer pipes are entered from rim of a cup l, after being exchanged heat along the 6th U-shaped heat-transfer pipe, treat cold
The most of condensation of solidifying gas becomes liquid, and volume diminishes；Liquids and gases in 5th U-shaped heat-transfer pipe and the 6th U-shaped heat-transfer pipe
By being merged into after the collecting of three-way elbow all the way, the 7th U-shaped heat-transfer pipe is entered from rim of a cup m, along the 7th U-shaped heat-transfer pipe heat exchange
Afterwards, dispenser component 8 is entered by rim of a cup n, and evaporation core body is flowed out along dispenser component 8, realize that bottom stream is double and enter singly to go out.
When cooling, gas-liquid mixture enters the 7th U-shaped heat-transfer pipe from rim of a cup n, is exchanged heat along the 7th U-shaped heat-transfer pipe
Afterwards, the 5th U-shaped heat-transfer pipe and the 6th U-shaped heat-transfer pipe are entered from rim of a cup m, the gas-liquid mixture coolant in the 7th U-shaped heat-transfer pipe leads to
Two branch roads are separated into after crossing three-way elbow：
Into the 5th U-shaped heat-transfer pipe coolant exchanged heat along the 5th U-shaped heat-transfer pipe after, from rim of a cup e enter the 3rd U-shaped biography
Heat pipe, after being exchanged heat along the 3rd U-shaped heat-transfer pipe, enters the first U-shaped heat-transfer pipe from rim of a cup b, is changed along the first U-shaped heat-transfer pipe
After heat, gas-liquid mixture coolant major part flashes to gaseous state, and volume becomes big；
Into the 6th U-shaped heat-transfer pipe coolant exchanged heat along the 6th U-shaped heat-transfer pipe after, from rim of a cup l enter the 4th U-shaped biography
Heat pipe, after being exchanged heat along the 4th U-shaped heat-transfer pipe, enters the second U-shaped heat-transfer pipe from rim of a cup g, is changed along the second U-shaped heat-transfer pipe
After heat, gas-liquid mixture coolant major part flashes to gaseous state, and volume becomes big；
Gaseous coolant in first U-shaped heat-transfer pipe and the second U-shaped heat-transfer pipe enters collecting pipe component 7, and along discharge
Component 7 flows out evaporation core body, realize bottom stream list enter it is double go out.
