In operation, which passes through the distributor.The distributor, which includes, i) is configured for the liquid
The upstream portion and ii of the entrance of refrigerant) be configured for the liquid refrigerant outlet downstream part.These fins exist
Extend between the upstream portion and the downstream part.
Variant according to the present invention, each access have flat parallelepiped form.Since each access is with flat
Flat shape, so the distance between two continuous slabs is small compared with the length and width of each continuous slab.Preferably,
The all or some of these fins extend to next plate from a plate.In other words, these fins are contacted with two plates.It is this
Construction allows in these fin brazeds to two plates, and which increase the mechanical strengths of the distributor.
In this application, term " ... direction on " refer to it is substantially parallel or basic with another direction or plane
Upper conllinear direction.
According to one embodiment of present invention, the volume of corresponding assignment channel be total volume less than 15%, it is preferably small
In 10%, which is delimited by following item:
- i) fin with overflow openings,
- ii) it is fixed to the plate on the low portion of the fin with overflow openings, and
- iii) be located at the fin with overflow openings fast upstream fin.
Therefore, because the volume of the assignment channel, these fins with overflow openings cannot cause too big load to be damaged
It loses.Low-load loss avoids the flowing for reducing the liquid refrigerant by these fins with overflow openings, this allows this
The optimum apjustment of flowing.Therefore, these have the function of that the fin of overflow openings is completed to distribute the liquid refrigerant, only generate low
Load loss.Each assignment channel is by least one low portion and by being fixed at least one described low portion
Plate limits.
According to an embodiment of the invention, these overflow openings are evenly distributed on fin in the transverse direction.
Therefore, equally distributed overflow openings allow the maximum distributing uniformity of the liquid refrigerant.Alternatively, certain
A little overflow openings can be unevenly distributed in the transverse direction.
According to one embodiment of present invention, aperture opening ratio, the aperture opening ratio include
It is located at the gross area of the overflow openings in the fin with overflow openings as molecule, and
The gross area in the face of the fin with overflow openings as denominator,
It is between 10% and 50%, preferably between 20% and 40%.
Therefore, the load loss that such aperture opening ratio helps to make the fin by these with overflow openings to generate is minimum
Change, while ensuring enough flowings in the distributor.
According to one embodiment of present invention, each overflow openings have in 1.5mm2With 10.0mm2Between, preferably exist
2.0mm2With 5.0mm2Between area.
Therefore, such area avoids floods each overflow openings completely, this helps not reduce through each fin
The flowing of liquid refrigerant.
Variant according to the present invention, some overflow openings have for example circular form of ellipse.Therefore, such shape mentions
Progressively increased overflow openings width is supplied, when the flowing of liquid refrigerant increases, which has limited the liquid refrigerants
Highly.
Variant according to the present invention, some overflow openings have the triangle shape for being directed toward at least one low portion
Formula.Therefore, such shape provides progressively increased overflow openings width, when the flowing of liquid refrigerant increases, this limit
The height of the liquid refrigerant is made.
According to one embodiment of present invention, between being measured in the transverse direction between two continuous overflow openings
Every being between 1mm and 6mm.
Therefore, such interval assists in ensuring that liquid refrigerant evenly distributing in the transverse direction, while making to pass through this
The load loss that a little fins with overflow openings generate minimizes.
Variant according to the present invention, the interval is constant for the overflow openings of at least one fin.
Therefore, such interval facilitates the distributing uniformity for making the liquid refrigerant in transverse direction maximization.
In one embodiment of the invention, in i) overflow openings and ii) it is fixed at least one described low portion
On plate between minimum range between 1mm and 4mm, for corresponding fin overflow openings it is most of or all, should
Minimum range is preferably identical.
Therefore, such minimum range allows assignment channel to have relatively large volume, this allows to limit in the distributor
The fin with overflow openings quantity.
According to one embodiment of present invention, several fins are with the corresponding upper part with overflow openings.
In other words, there are several allocated phases of the liquid refrigerant, this help keeps the uniformity of this distribution maximum
Change.
According to one embodiment of present invention, these overflow openings being present in fin are relative to being present in adjacent fins
In these overflow openings in the transverse direction offset orientation.
Therefore, such offset between overflow openings helps to increase point of the liquid refrigerant in the transverse direction
With uniformity.

Offset accounts between the 40% and 60% of the length at the interval.
In other words, the overflow openings of the continuous fin of two be arranged in being substantially offset from one another on the longitudinal direction.
Therefore, the value of such offset between overflow openings helps point for making the liquid refrigerant in the transverse direction
It is maximized with uniformity.
According to one embodiment of present invention, at least one fin has flat pattern and extends until described two
Continuous slab and each of described two continuous slabs are obliquely run out to, so as to vertical with these plates and the transverse direction
Plane in section in form closed bevel, the oblique angle preferably between 30 ° and 60 °, further preferably at 40 ° and
Between 50 °.
Therefore, such flat inclined fin occupies relatively small space and is readily attached on these plates.

Length, and each fin has the width for being parallel to the transverse direction between 4mm and 10mm, and each fin being capable of example
Such as there is equal length and width.
Therefore, such length and width allows a large amount of fin to be incorporated in the distributor, and which increase the liquid systems
The distributing uniformity of cryogen.
Variant according to the present invention, each fin have for example by being brazed the fixed part being fixed on plate.
Therefore, such fixed part allows each fin to be attached on these plates in a simple manner.
Variant according to the present invention, one and preferably each overflow openings are by openings (through orifice)
It limits.Alternatively, at least one overflow openings can be by extending until the recess at the edge of corresponding fin limits.
According to one embodiment of present invention, which includes at least one fin, which has
Aperture and the upstream for being placed on fin of the one or more with overflow openings, these apertures are distributed in the transverse direction
On, the quantity of the overflow openings of each fin is 3 times bigger than the quantity in the aperture of each fin, preferably 5 times big.
Therefore, these fins with aperture can complete control into the distributor by generating high load loss
The function of the flowing of liquid refrigerant, and these have the fin for overflowing opening complete while generating only low-load loss on the contrary
At distribution function.Which has limited the quantity for the component being mounted in the distributor, because due to the fin with aperture,
It does not need to provide perforation stick (such as in WO-A-2011110782) to generate high load loss.
Variant according to the present invention, at least two fins have aperture, and the quantity in the aperture of each fin is being from upstream to
Increase on the direction in downstream.
Therefore, these fins with aperture allow access into the best control of the flowing of the liquid refrigerant of the distributor
System.
Variant according to the present invention, be located at most upstream the fin with aperture transverse direction on measure, two
Being located at interval between 40mm and 60mm between a continuous aperture, and in the transverse direction for the fin with aperture for being located at most downstream
Measured on direction, being located at interval between 6mm and 20mm between two continuous apertures.
Therefore, fin with aperture positioned at most upstream has least aperture, and has hole positioned at most downstream
The fin of mouth has most apertures, these fins with overflow openings are in the fin with aperture positioned at most downstream
Downstream.
Therefore, the load loss that the fin by these with aperture generates is from upstream to downstream and reduces, and the liquid refrigerating
The distributing uniformity of agent increases.
Variant according to the present invention, at least one fin, other than these overflow openings, can have at least one
The purge hole arranged at the bottom of the low portion.Then, the assignment channel is by several part shapes being split into two halves by purge hole
At the liquid refrigerant can flow through the purge hole.Such purge hole allows the emptying of the assignment channel.Advantageously, should
Or the area of each purge hole is less than the area of overflow openings.Therefore, there is relatively low flow velocity by the flowing of the purge hole,
This avoidance breakout passes through the flowing of each overflow openings close to the purge hole.
Variant according to the present invention, for giving these openings of fin or the gross area of these overflow openings in the longitudinal direction
Increase on direction, is preferably increased by increasing quantity and/or the area that these are open.
In this way, the liquid decline in the distributor is remoter, and the spacing between these openings is smaller.Start
When, if liquid poorly distributes, it is forced laterally to recycle the adjacent apertures until same fin.It is open at two
Between distance it is bigger, reallocation on the width is more effective.
Secondly, the purpose of the present invention is a kind of for distributing the distribution method of liquid refrigerant, this point in a heat exchanger
Method of completing the square the following steps are included:
Implement distributor according to the present invention,
Liquid refrigerant is transmitted in each access and generally in a longitudinal direction,
Allow liquid refrigerant via the fin with aperture orifice flow,
Each assignment channel is filled, so that liquid refrigerant is flowed via these overflow openings.
