Condensation, can also be evaporated as evaporator to refrigerant.
As described in Figure 1, parallel-flow heat exchanger 100 according to embodiments of the present invention includes：First header 1, the first pipe 2,
Second pipe 3, the second header 4, multiple flat tubes 5 and allocation component 6.
Two the first upper chamber 111 spaced apart and the first lower chambers are separated into by first partition 11 in first header 1
112, " the first upper chamber 111 and the first lower chambers 112 are spaced apart " refers between the first upper chamber 111 and the first lower chambers 112
Do not connect.First pipe 2 connects with the first upper chamber 111, and the second pipe 3 connects with the first lower chambers 112, wherein the first pipe 2 and
Input pipe or efferent duct of two pipes 3 respectively as refrigerant.
Second header 4 be arranged in parallel with the first header 1, alternatively, parallel-flow heat exchanger 100 is being installed into refrigeration
When in equipment, the first header 1 and the second header 4 can be with vertically extending, positioned at intervals installation in left-right direction, examples
Direction as shown in Figure 1.Wherein, multiple sub-chamber 41, more sub- chambers are separated into by multiple partition components in the second header 4
Room 41 is connected by the passage formed on partition component, that is to say, that refrigerant can mutually flow in multiple sub-chamber 41
Dynamic, mixing.
In the example depicted in fig. 1, partition component is second partition 71, and wherein passage is to be formed on second partition 71
Bulkhead through-hole 711, that is to say, that multiple sub-chamber 41 are interconnected by the bulkhead through-hole 711 on second partition 71 respectively, system

The both ends of setting fin (not shown) between 5, the first header 1 and the second header 4 are provided with blanking cover 42, close to play
Envelope acts on.
Need exist for explain, when parallel-flow heat exchanger 100 as condenser when, because refrigerant condensation when refrigerant
Pressure ratio it is higher, when the Sizes of the bulkhead through-hole 711 of second partition 71, refrigerant is produced by bulkhead through-hole 711
Raw pressure drop accounts for the proportion very little of whole refrigerant condensing pressure, and the volume of unit mass refrigerant can shrink when condensing,
Therefore refrigerant side condensation side passes through the no too big problem of bulkhead through-hole 711；But when parallel-flow heat exchanger 100 is used as evaporator
When, its situation is then changed, and when refrigerant evaporates, the refrigerant in the second header 4 is gas-liquid two-phase state, very aobvious
The refrigerant of right second header 4 will make a reasonable distribution in each sub-chamber 41, but when evaporating refrigerant pressure ratio
Rise condensation when it is much lower, therefore refrigerant the second header 4 have gas-liquid layering, because fluid density is bigger than gas,
Therefore the lower liquid of the second header 4 is more, and upper liquid is few, so as to cause the refrigerant point in superposed sub-chamber 41
With unbalanced, and the refrigeration by adjusting the size of the bulkhead through-hole 711 on second partition 71 to adjust in corresponding sub-chamber 41
Agent sendout, be also only applicable to top the demand of sub-chamber 41 refrigerant amount less than bottom sub-chamber 41 situation；On and
The refrigerant amount of the demand of sub-chamber 41 in portion is more than the situation of bottom sub-chamber 41, is just difficult to reach.
Thus the present inventor just proposes sets allocation component 6 to solve the problem on the second header 4, has
Body, as shown in figure 1, allocation component 6 includes the distributor disk 61 with distribution cavity and the entrance pipe connected respectively with distribution cavity
62 and at least one export pipeline 63, entrance pipe 62 connects with being located at the sub-chamber 41 of bottom in multiple sub-chamber 41, extremely
Few one outlet pipeline 63 connects with remaining sub-chamber 41 respectively.That is, the quantity of entrance pipe 62 and export pipeline 63
Sum is identical with the quantity of sub-chamber 41 and corresponds, such as sub-chamber 41 includes two, then export pipeline 63 includes one；
Such as sub-chamber 41 includes three, then export pipeline 63 include two and two export pipelines 63 respectively with positioned at the top and in
Between sub-chamber 41 connect；Such as in the example shown in Fig. 1, partition component includes three, three partition components are by the second afflux
Four sub-chamber 41 are separated into pipe 4, the export pipeline 63 of allocation component 6 is three, and three export pipelines 63 correspond to four respectively
The sub- chamber 41 of its excess-three of the sub-chamber 41 of removing bottom in individual sub-chamber 41；For example partition component includes four again,
Four partition components will be separated into five sub-chamber 41 in the second header 4, the export pipeline 63 of allocation component 6 is four, and four
Individual export pipeline 63 corresponds to remaining four sub-chamber 41 of the sub-chamber 41 of the removing bottom in five sub-chamber 41 respectively.Its
In, above-mentioned example can be effectively distributed entering the refrigerant in the second header 4, avoid refrigerant air-liquid
Layering is excessively serious, improves heat transfer effect.
Alternatively, a hole, entrance pipe 62 are provided with the bottom sides of the sub-chamber 41 of the bottom of the second header 4
It is inserted into by the hole in the sub-chamber 41 of bottom, the other end of entrance pipe 62 connects with the distribution cavity in distributor disk 61.
In example as shown in Figure 1, one end of three export pipelines 63 can pass through the hole on the corresponding upper side wall of sub-chamber 41 respectively
It is inserted into corresponding sub-chamber 41, the other end of three export pipelines 63 connects with the distribution cavity in distributor disk 61.
Advantageously, the partition component in multiple partition components positioned at bottom is located at same level height with first partition 11
On, the flat tube 5 so connected with the first lower chambers 112 is also while the sub-chamber 41 positioned at bottom only with the second header 4
Connection, can so make the structure of parallel-flow heat exchanger 100 more reasonable, the utilization rate highest of flat tube 5, not have the quilt of flat tube 5
Short-circuit (i.e. refrigerant can flow through all flat tubes 5).
Below with reference to Fig. 1, the stream of refrigerant when description parallel-flow heat exchanger 100 is respectively as condenser and evaporator
To.
When parallel-flow heat exchanger 100 is as condenser, its refrigerant flow direction is as shown in the filled arrows in Fig. 1, high temperature
The refrigerant of high pressure enters in the first upper chamber 111 of the first header 1 from the first pipe 2, is then dispensed for and the first upper chamber
Condensed in the flat tube 5 of 111 connections, refrigerant enters in the sub-chamber 41 of the second header 4 after being come out from flat tube 5, passes through
The aperture of rational bulkhead through-hole 711 is set, it is ensured that most of refrigerants pass through from the bulkhead through-hole 711 of second partition 71
And enter in the sub-chamber 41 of bottom, then refrigerant is redistributed to what is be connected with the sub-chamber of the bottom 41
Continue to condense in flat tube 5.After the completion of condensation, refrigerant is collected in the first lower chambers 112 of the first header 1, most afterwards through
Two pipes 3 flow out.
When parallel-flow heat exchanger 100 is as evaporator, its refrigerant flow direction is as shown in the hollow arrow in Fig. 1, low pressure
The refrigerant of gas-liquid two-phase by the second pipe 3 enter the first header 1 the first lower chambers 112 in, then refrigerant be assigned to
It is evaporated in the flat tube 5 that first lower chambers 112 are connected, after flowing through corresponding flat tube 5, refrigerant has been evaporated after a part again
Enter in the sub-chamber 41 positioned at bottom of the second header 4, the refrigerant being now placed in the sub-chamber 41 of bottom
It can be layered, the larger liquid refrigerant of density is largely sunken to the bottom of the sub-chamber 41, therefore liquid refrigerant can be from distribution
The entrance pipe 62 of component 6 flows into, and is assigned in distributor disk 61 in each export pipeline 63, through corresponding export pipeline 63
Guiding have respectively entered in the corresponding sub-chamber 41 of the second header 4, the refrigerant in corresponding sub-chamber 41 separately flows into
In the flat tube 5 connected with each sub-chamber 41, in corresponding flat tube 5, each road refrigerant continues to flow and evaporated, until refrigerant
Collect in the first upper chamber 111 of the first header 1, most flow out parallel-flow heat exchanger 100 through the first pipe 2 afterwards.
By in above description as can be seen that parallel-flow heat exchanger 100 according to embodiments of the present invention, kind of refrigeration cycle and
What heating circulating refrigerant was sidled in the second header 4 is different passages, especially when parallel-flow heat exchanger 100 is used as evaporator
When, refrigerant can be allocated by allocation component 6, the mistake for avoiding the refrigerant air-liquid in superposed flat tube 5 from being layered
In serious, by adjusting the length or internal diameter of export pipeline 63, evaporation process is tended to be optimal, finally solve heating substantially and follow
The refrigerant air-liquid layering of ring and distribution non-uniform phenomenon, substantially increase the changing in different modes of parallel-flow heat exchanger 100
The thermal efficiency.
To sum up, by setting allocation component 6, the problem of refrigerant distribution is uneven can be efficiently solved, is improved parallel
The heat exchange efficiency of heat exchanger 100 is flowed, and the structure of allocation component 6 is reliable, therefore can be applied to produce in enormous quantities.
Parallel-flow heat exchanger 100 according to embodiments of the present invention, due to being formed on the second partition 71 in the second header 4
There is bulkhead through-hole 711, each sub-chamber 41 is connected by bulkhead through-hole 711, so when outlet distributes refrigerant, adjacent son
Have a small amount of refrigerant between chamber 41 to swap by bulkhead through-hole 711, therefore the parallel-flow heat exchanger 100 is being steamed
It can also be influenceed to a certain extent by bulkhead through-hole 711 when sending out device.
Thus the present inventor is further improved partition component, and root is described below with reference to Fig. 2-Fig. 6
According to the partition component of different embodiments of the invention.
As shown in Fig. 2-Fig. 6, device in one-way on state 72 can also be according to the partition component of the present embodiment, that is to say, that
Above-mentioned second partition 71 can be replaced by device in one-way on state 72.Device in one-way on state 72 is configured to unidirectionally lead from top to bottom
Logical, wherein above-below direction is the direction marked in Fig. 1, i.e. the device in one-way on state 72 can allow refrigerant to flow from the top down
It is dynamic, and prevent refrigerant from flowing from bottom to top.So when parallel-flow heat exchanger 100 is as condenser, in the second header 4
Middle refrigerant can be flowed in the sub-chamber 41 of lower section by device in one-way on state 72 from the sub-chamber 41 of top；When concurrent flow changes
When hot device 100 is as evaporator, refrigerant flows from bottom to top in the second header 4, because device in one-way on state 72 prevents
The flowing of refrigerant from bottom to top, thus the refrigerant in the second header 4 separated by device in one-way on state 72 and can not be
Circulated in each sub-chamber 41, now refrigerant is assigned to each sub-chamber 41 by can only by allocation component 6
In, it is possible thereby to avoid the influence that the bulkhead through-hole 711 of second partition 71 as shown in Figure 1 is distributed refrigerant.
In one embodiment of the invention, as shown in Fig. 2-Fig. 3, device in one-way on state 72 includes：Cylinder 721 and partition
722, cylinder 721 is adapted to fit in the second header 4, and the external diameter of cylinder 721 is preferably equivalent to or slightly smaller than the second header 4
Internal diameter so that cylinder 721 can stably, be conveniently provided in the second header 4.Wherein, the open at its lower end of cylinder 721 and
Upper end has apical pore 7211, and apical pore 7211 runs through the roof of cylinder 721, and partition 722 is movably arranged in cylinder 721, partition
722 external diameter is slightly smaller than the internal diameter of cylinder 721.Wherein, partition 722 is configured to block when it is bonded with the upper end of cylinder 721
Apical pore 7211 and liquid positioned at partition 722 above can discharge cylinder 721 downwards by it when it departs from 721 upper end of cylinder,
That is, apical pore 7211 and the position when it departs from the roof of cylinder 721 are blocked when partition 722 is bonded with the roof of cylinder 721
Liquid above partition 722 can discharge cylinder 721 downwards by it.
Thus,, can be with when refrigerant flows from top to bottom when device in one-way on state 72 is installed in the second header 4
Entered by apical pore 7211 in cylinder 721, due to the flowing pressure of refrigerant, partition 722 is pulled to the bottom of cylinder 721,
Now partition 722 can go out for cold-producing medium stream, so as to which refrigerant can discharge cylinder 721, can so utilize one-way conduction to fill
Put the adjacent sub-chamber 41 of 72 connections；When refrigerant flows from bottom to top, partition 722 is made in the flowing pressure of refrigerant first
Moved up under, when partition 722 is pulled to the top of cylinder 721, partition 722 just blocks apical pore 7211, now freezes
Agent will not be entered in adjacent sub-chamber 41 by cylinder 721.To sum up, it is single when parallel-flow heat exchanger 100 is as condenser
Adjacent sub-chamber 41 can be connected to conducting device 72；When parallel-flow heat exchanger 100 is as evaporator, device in one-way on state
72 can block adjacent sub-chamber 41.The height of its middle cylinder body 721 is less than 30mm, because the structure of the second header 4 limits,
By the way that the height of cylinder 721 is controlled in the range of less than 30mm, after being located at so as to cylinder 721 in the second header 4
Excessive interference will not be produced, so as to so that there is provided the structure of the second header 4 of cylinder 721 is unaffected.
In the specific example of the present invention, as shown in Fig. 2 having multiple partition holes through it on partition 722
7221, projection of the apical pore 7211 on partition 722 is spaced apart with multiple partition holes 7221, i.e. apical pore 7211 and partition hole 7221
It will not overlap, so when partition 722, which is moved to, to be contacted with the roof of cylinder 721, partition 722 will block apical pore 7211, with
Refrigerant is prevented to pass through.When partition 722 is moved to the bottom of cylinder 721, due to the bottom-open of cylinder 721, partition hole
7221 will not be blocked completely, therefore refrigerant can be entered by apical pore 7211 and partition hole 7221 respectively, outflow tube
721.Preferably, multiple partition holes 7221 set and are uniformly distributed circumferentially adjacent to the edge of partition 722, thus make partition 722
Structure it is simple and rationally.In the example of the present invention, partition hole 7221 is four.
In another specific example of the present invention, shown example, different from the example shown in Fig. 2 as shown in Figure 3
It is that there is at least one groove 7222 inwardly concaved on the edge of partition 722.In projection in the vertical direction, groove
7222 are not overlapped with apical pore 7211, and the through hole for refrigerant flowing is limited between the inwall of groove 7222 and cylinder 721.It is optional
Ground, groove 7222 are formed as square groove, dovetail groove or deep-slotted chip breaker, can so make the shape of groove 7222 more diversified, recessed
Groove 7222 is adapted to the use of more industrial situations.Alternatively, groove 7222 is 3-8.
In another embodiment of the present invention, as Figure 4-Figure 6, device in one-way on state 72 includes：It is adapted to fit in
Body 723 and closed plate 724 in second header 4.Body 723 is formed as tabular, has on body 723 and runs through its body
Hole 7231, closed plate 724 are connected on the lower surface of body 723, and closed plate 724 is opening the open position of body apertures 7231
It is movable between the closed position of closing body apertures 7231.Specifically, when refrigerant flows from the top down, closing can be forced
Plate 724 opens body apertures 7231；When refrigerant flows from bottom to top, closed plate 724 can be forced to close body apertures 7231.
In the specific example of the present invention, as shown in figure 4, closed plate 724 is pivotably coupled under body 723
On surface.That is one end of closed plate 724 is connected on the lower surface of body 723, and the other end is free end, can be around body 723
Carry out the pivot of certain angle.Specifically, there is the first upwardly recessed recess 7232 on the lower surface of body 723, wherein
Body apertures 7231 are formed at the first recess 7232, and closed plate 724 is as pivotally connected to the side wall of the first recess 7232
On, the lower surface of closed plate 724 is concordant with the lower surface of body 723 when closed plate 724 closes body apertures 7231.It is possible thereby to make
Body 723 is simple and reasonable for structure with closed plate 724, and because closed plate 724 is at enclosed body hole 7231, closed plate
724 lower surface is concordant with the lower surface of body 723, is produced thus without the flowing to the refrigerant in the second header 4 dry
Disturb.Alternatively, the first recess 7232 is formed as rectangular area, and thus the structure of body 723 is simpler.
In another specific example of the present invention, have as shown in Figure 5 and Figure 6, on the lower surface of body 723 concave up
