The fin generally extended in a lateral direction in one of the First Series or each path, the horizontal direction
It is orthogonal and parallel with these plates with the longitudinal direction, each passageways houses of First Series phase each other on the longitudinal direction
After several fins, each fin have is configured as allow liquid refrigerant flow aperture；
At least one fin has upper part and low portion, when the distributor is in operation and the longitudinal direction
When extending on the vertical direction, the height of the upper part is more than the height of the low portion,
At least one described low portion and the plate being fixed at least one described low portion are limited at least
One be arranged to the conduction liquid cryogen on the horizontal direction assignment channel,
The aperture of at least one fin is formed by the overflow openings at least one described upper part, these
Overflow openings are configured such that the liquid refrigerant is via this when at least one described assignment channel hydraulically full refrigerant
A little overflow openings flowings.
In other words, the or each assignment channel forms a type of groove, and the groove is in these overflow openings and the bottom
Extend between part and the crosspoint for the plate being fixed on this low portion.When the distributor operation when, should or
Each assignment channel is generally horizontal.
Therefore, the or each assignment channel allows in the transverse direction side with cooperating for the overflow openings of one or more fins
The liquid refrigerant is distributed as homogeneously as possible upwards, and the solid deposits of impurity in the heat exchanger are restricted or prevented in this
Risk.
Extend on two dimensions (length and width) of these plates respectively on the longitudinal direction and the horizontal direction.Every
In individual path, these fins have elongated form and extended on the width (horizontal direction) of two continuous slabs.
When the distributor is in operation, the longitudinal direction is vertical.The liquid refrigerant is under gravity generally
Flowed on the longitudinal direction.Therefore, the liquid refrigerant generally vertically flows on descent direction.
According to the variant of the present invention, the distributor can include the plate quantity more than 20 or even greater than 100.Therefore,
These plate shapes are folded into sheetpile, and the path for the liquid refrigerant is defined between the plates, in some cases with for
The conduit alternating of the heat production fluid.The distributor can have the liquid refrigerant number of vias more than 10 or even greater than 50

In operation, the liquid refrigerant passes through the distributor.The distributor has：I) it is arranged to the liquid
The upstream portion of the entrance of refrigerant, and ii) be arranged to the liquid refrigerant outlet downstream part.These fins exist
Extend between the upstream portion and the downstream part.
According to the variant of the present invention, each path has flat parallelepiped form.Due to each path have it is flat
Flat shape shape, so the distance between two continuous slabs is small compared with the length and width of each continuous slab.Preferably,
These fins all or some extend to next plate from a plate.In other words, these fins are contacted with two plates.It is this
Construction allows these fin brazeds to two plates, and which increase the mechanical strength 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 cumulative volume be less than 15%, it is preferably small
In 10%, the cumulative volume is delimited by following item：
- i) there is the fin of overflow openings,
- ii) plate on the low portion of the fin with overflow openings is fixed to, and
- iii) fin of the fast upstream of the fin with overflow openings described in.
Consequently, because the volume of the assignment channel, there is the fin of overflow openings too big load can not be caused to damage for these
Lose.Low-load loss avoids the flowing for reducing the liquid refrigerant by these fins with overflow openings, and this allows this
The optimum apjustment of flowing.Therefore, there is the fin of overflow openings to complete to distribute the function of the liquid refrigerant for these, only produce low
Load loss.Each assignment channel is by least one low portion and by being fixed at least one described low portion
Plate is limited.
Embodiments in accordance with the present invention, these overflow openings are evenly distributed on fin on the horizontal direction.
Therefore, equally distributed overflow openings allow the maximum distributing uniformity of the liquid refrigerant.Alternately, certain
A little overflow openings can unevenly be distributed on the horizontal direction.
According to one embodiment of present invention, aperture opening ratio, the aperture opening ratio has：
- be located at overflow openings fin in overflow openings the gross area as molecule, and
The gross area in the face of-fin with overflow openings as denominator,
It is between 10% and 50%, preferably between 20% and 40%.
Therefore, such a aperture opening ratio contributes to the load loss for producing the fin for having overflow openings by these 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 a area is avoided floods each overflow openings completely, and this helps not reduce by each fin
The flowing of liquid refrigerant.
According to the variant of the present invention, some overflow openings have the form of ellipse such as circle.Therefore, such a shape is carried
Progressively increased overflow openings width is supplied, when the flowing increase of liquid refrigerant, which has limited the liquid refrigerant
Highly.
According to the variant of the present invention, some overflow openings have the triangle shape for pointing at least one low portion
Formula.Therefore, such a shape provides progressively increased overflow openings width, when the flowing increase of liquid refrigerant, this limit
The height of the liquid refrigerant is made.
According to one embodiment of present invention, between being measured between two continuous overflow openings on the horizontal direction
Every being between 1mm and 6mm.
Therefore, such a interval assists in ensuring that liquid refrigerant evenly distributing on the horizontal direction, while making by this
The load loss that a little fins with overflow openings are produced is minimized.
According to the variant of the present invention, the interval is constant for the overflow openings of at least one fin.
Therefore, such a interval contributes to the distributing uniformity for making the liquid refrigerant on the horizontal direction to maximize.
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 be located between 1mm and 4mm, for corresponding fin overflow openings it is most of or all, should
Minimum range is preferably identical.
Therefore, such a minimum range allows assignment channel to have relatively large volume, and this allows to limit in the distributor
The fin with overflow openings quantity.
According to one embodiment of present invention, several fins have the corresponding upper part with overflow openings.
In other words, there are several allocated phases of the liquid refrigerant, this help makes the uniformity of this distribution maximum
Change.
According to one embodiment of present invention, it is present in these overflow openings in fin relative to being present in adjacent fins
In these overflow openings on the horizontal direction offset orientation.
Therefore, such a skew between overflow openings helps to increase point of the liquid refrigerant on the horizontal direction
With uniformity.

Skew is accounted between the 40% and 60% of the length at the interval.
In other words, the overflow openings for two continuous fins being arranged in being substantially offset from one another on the longitudinal direction.
Therefore, the value of such a skew between overflow openings helps point for making the liquid refrigerant on the horizontal direction
Maximized with uniformity.
According to one embodiment of present invention, at least one fin has flat pattern and extended until described two
Continuous slab and each in described two continuous slabs is obliquely run out to, so as to vertical with these plates and the horizontal 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 a flat inclined fin occupies relatively small space and is readily attached on these plates.
According to one embodiment of present invention, each fin have between 4mm and 10mm parallel to the longitudinal direction
Length, and each fin has the width parallel to the horizontal direction between 4mm and 10mm, and each fin being capable of example
Such as there is equal length and width.
Therefore, such a length and width allows substantial amounts of fin to combine in the distributor, and which increase the liquid system
The distributing uniformity of cryogen.
According to the variant of the present invention, each fin has for example is fixed to the fixed part on plate by soldering.
Therefore, such a fixed part allows each fin to be attached in a straightforward manner on these plates.
According to the variant of the present invention, one and preferably each overflow openings are by openings (through orifice)
Limit.Alternately, at least one overflow openings can be by extending until the recess at the edge of corresponding fin is limited.
According to one embodiment of present invention, the distributor includes at least one fin, and at least one fin has
Aperture and the upstream for being placed on one or more fins with overflow openings, these apertures are distributed in the horizontal direction
On, the quantity in aperture of the quantity than each fin of the overflow openings of each fin is big 3 times, preferably big 5 times.
Therefore, there is the fin in aperture can complete control into the distributor by producing high capacity loss for these
The function of the flowing of liquid refrigerant, and these have the fin for overflowing opening conversely complete while generation only low-load is lost
Into distribution function.Which has limited the quantity for the part being mounted in the distributor, because due to the fin with aperture,
Perforation rod (as in WO-A-2011110782) need not be provided to produce high capacity loss.
According to the variant of 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 have the fin in aperture allow access into the distributor liquid refrigerant flowing optimal control
System.
It is being measured on the horizontal direction positioned at the fin with aperture of most upstream, two according to the variant of the present invention
Being located at interval between 40mm and 60mm between individual continuous aperture, and in the transverse direction of the fin with aperture positioned 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 minimum aperture, and has hole positioned at most downstream
The fin of mouth has most apertures, and there is the fin of overflow openings to be in the fin with aperture positioned at most downstream for these
Downstream.
Therefore, downstream is from upstream to by these load losses that there is the fin in aperture to produce to reduce, and the liquid refrigerating
The distributing uniformity increase of agent.
According to the present invention variant, at least one fin, in addition to 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
Into the liquid refrigerant can flow through the purge hole.Such a 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,
The flowing that this avoidance breakout passes through each overflow openings close to the purge hole.
According to the variant of the present invention, for giving these openings of fin or the gross area of these overflow openings in the longitudinal direction
Increase on direction, preferably increased by increasing the quantity and/or area of these openings.
By this way, the liquid decline in the distributor is more remote, and the spacing between these openings is smaller.Start
When, if liquid is poorly distributed, it is forced laterally to circulate the adjacent apertures until same fin.It is open at two
Between distance it is bigger, the reallocation on width is more effective.
Secondly, the purpose of the present invention is a kind of distribution method for being used to distribute liquid refrigerant in a heat exchanger, this point
Method of completing the square comprises the following steps：
- implement according to distributor of the invention,
- liquid refrigerant is transmitted in each path and generally in a longitudinal direction,
- allow liquid refrigerant via the orifice flow of the fin with aperture,
The each assignment channel of-filling so that liquid refrigerant flows via these overflow openings.
The invention further relates to a kind of heat exchanger, the heat exchanger is configured as heat from least one heat production fluid
(such as nitrous oxide) is delivered at least one cryogenic fluid (such as oxygen), and the heat exchanger includes at least one heat exchange list
Member, at least one liquid refrigerant entrance, the heat exchanger are characterised by including according to any one of preceding claims institute
