Design, if the optimal cold target for not reaching design in the case of optimal still with flow path designs of system configuration or need to increase cold
During amount, typically area and the interior of heat exchanger can be increased by the physical dimension for expanding indoor set and the length for increasing heat exchanger
The air circulation of machine reaches the performance objective compared with High cooling power, therefore, if to develop cold be twice or higher cold
The product of amount, then the size of indoor set is accomplished by adjustment, and can thus increased die cost and related cost, while
The increase of size, also influences the attractive in appearance of room and occupies indoor more spaces.
At present, it is existing increase air-conditioning cold flow scheme be, by improve the heat exchange efficiency of heat exchanger to realize chilling requirement,
Evaporator stream enters three and goes out scheme using One In and Two Out or three, and One In and Two Out evaporator refrigerant Pressure Loss Ratio is larger, causes heat exchange
Efficiency comparison is low, and especially refrigerating capacity is relatively low, and stream is more long, and flow resistance is bigger, causes to lead with the reduction of velocity in pipes and changes
Heating rate reduction, also easily produces refrigerant bias current, causes and is difficult to effectively heat exchange, three enter three go out the Pressure Loss Ratio of stream evaporator compared with
Small, heat exchange efficiency is higher, but if the design of stream uniformity is unreasonable, the refrigerant between each road of heat exchanger occurs distribution not
Uniform situation, shunting inequality causes the shunting temperature difference big, influences overall performance.
In addition to above scheme, also have using the scheme of penstock to solve, for example with evaporator back or the preceding back of the body
The scheme of pipe carries out increase heat exchange area, and the windage of penstock side, meeting can be increased to reach corresponding cold requirement, but after penstock
The air circulation of indoor set is caused to diminish, so that influence to reduce the heat exchange efficiency of evaporator, meanwhile, if shunted not after penstock
There is also the associated reliability problems such as condensation or leak.

The evaporator flow passage structure 1 that example is provided, or such as whole beneficial effects of the evaporator that above-mentioned any embodiment is provided, differ herein
One enumerates.
Embodiment according to the fourth aspect of the invention, the present invention proposes a kind of air-conditioner, including：Any implementation as described above
The evaporator flow passage structure 1 that example is provided；Or such as the evaporator of above-mentioned any embodiment offer；Or as above-mentioned any embodiment is provided
Air conditioner room unit.
The air-conditioner that the present invention is provided, because of the evaporator flow passage structure 1 provided including such as above-mentioned any embodiment；Or as above
The evaporator of any embodiment offer is provided；Or the air conditioner room unit that such as above-mentioned any embodiment is provided, therefore, the present invention is provided
Air conditioner room unit there is the evaporator flow passage structure 1 that any of the above-described embodiment provides, or as above-mentioned any embodiment is provided
Evaporator, or such as whole beneficial effects of the air conditioner room unit that above-mentioned any embodiment is provided, it is numerous to list herein.
The evaporator flow passage structure 1 that the present invention is provided is improved to correlation technique, due to cold and the heat exchange of air-conditioner
The length of device is heat exchange area and follows air quantity and have difference, and the actually size of air conditioner room unit and space is limited, if do not changed
Become the internal structure of heat exchanger to increase heat exchange area can only be the size by penstock or lengthening broadening air conditioner room unit
Solved, and the present invention is the internal structure by changing heat exchanger, that is, between improving the hole of fin 14 of evaporator flow passage structure 1
Increase heat exchange area away from the tube pitch with front and rear steaming, while the design of the heat exchanger flow of air conditioner room unit and air conditioner chamber
The incoming air area of interior machine and air channel are relevant, and the design of heat exchanger flow can influence the shunting conditions of heat exchanger, then can also influence
The production of the heat exchange amount of heat exchanger, whole function effect and condensation；As shown in Figures 1 to 5, due to air conditioner room unit heat exchanger
It is not smooth arc evaporator, each folding evaporator wind speed profile is simultaneously uneven, and refrigerant is entering evaporator flow passage structure 1
Vapour-liquid layering is likely to occur before each stream or vehicle repair major mixing is uneven, so that can not be evenly into evaporator stream knot
In each stream of structure 1, cause partial flowpafh liquid refrigerant on the high side, evaporation is incomplete, and another part stream vaporized refrigerant is inclined
Many, evaporation problems of excessive heat is serious.Easily cause evaporator outlet bias current excessive if each flow passage structure is unreasonable, whole machine can be influenceed
The reliability of system.As shown in Figure 6：By changing between the pitch of holes of fin 14 of heat exchanger and the pipe of front and rear steaming, conventional fin
14 pitchs of holes are in 21mm, and the present invention is configured pitch of holes and changes increasing using the spacing range between 18mm to 21mm
The area of hot device, while the refrigerant crushing of heat exchanger is reduced, and it is uneven according to the air quantity of air conditioner room unit heat exchanger
Situation, enters four schemes for going out to lift efficiency of heat exchanger using four, also, using etc. journey carry out group with the stream of the journey such as not
Close, be conducive to the stream stabilization of variable working condition, be not in that evaporator occur because secondary refrigerant leakage problem causes liquid supply rate few each
Individual stream goes out the larger generation condensation of the head piece temperature difference and blows the relevant issues such as water.
The evaporator flow passage structure 1 or the air-conditioner point liquid of evaporator or air conditioner room unit provided using the present invention are reached
Best effects, ability is optimal, and the air-conditioning internal machine size of meets the performance indications of two, rational pipeline cloth
The condensation problem for blowing water that it also avoid when this type evaporator works under high humidity conditions is put, through actual measurement, using the present invention
The evaporator flow passage structure 1 or evaporator or the air-conditioner of air conditioner room unit of offer, refrigerating capacity are obviously improved, refrigerating capacity
By ability originally with One In and Two Out 3500W, the ability level of 5000W is arrived in lifting, meanwhile, the ability point of other operating modes also reaches
To the performance requirement of 2.
In sum, the present invention is provided evaporator flow passage structure 1, evaporator, air conditioner room unit and air-conditioner, pass through
U pipes 10 are connected with semicircle connecting tube 12, and be arranged on fin 14 and form four road streams, and then refrigerant will enter four and goes out by four
Stream is exchanged heat, and reduces the stroke of refrigerant, and then improves heat exchange efficiency, simultaneously as the air quantity of heat exchanger cannot do
To substantially uniformity, and four road streams can be configured according to the difference of heat exchanger air quantity everywhere, and then can further be lifted
Heat exchange efficiency, and then air-conditioner heat exchange efficiency is improved, it is thereby achieved that in the case where air-conditioner compact is ensured, carrying
The performance of air-conditioner has been risen, the experience of user has been improved.
In the present invention, term " multiple " then refers to two or more, unless otherwise clearly restriction.Term " peace
