250 can have symmetrical shape.The partition 250 includes the ground for being defined as the reference line A1 and the outer peripheral surface 252 and meeting
The datum mark 256 of point.
Multiple inner tubes 240 can be multistage in the internal arrangement of the supercooling main body 210.As an example, multiple
The inner tube 240 includes: first row with pipe portion 241, and when using the flow direction of first refrigerant as benchmark, this first
Column are arranged in the lower part of the inside of the supercooling main body 210 with pipe portion 241;Secondary series matches pipe portion 243, and Xiang Suoshu first row is matched
The upside of pipe portion 241 separates arrangement;Third column match pipe portion 245, and Xiang Suoshu secondary series separates arrangement with the upside of pipe portion 243.
As an example, match multiple pipings of pipe portion 241 as shown in figure 8, constituting the first row, constitute secondary series with pipe portion
243 multiple pipings and the composition third column match multiple pipings of pipe portion 245, are arranged separately on identical height.Wherein,
Height can be regarded as: when regarding the datum mark 256 as origin, the reference line A1 extend direction on, away from for
At a distance from the datum mark 256 first reference line l1 tangent with the outer peripheral surface 252.

At the 4th reference line l4 at the center of multiple pipings of the third column with pipe portion 245.
The first row with pipe portion 241 and secondary series at a distance from being spaced apart of pipe portion 243, with the secondary series with pipe portion
243 with third column with pipe portion 245 be spaced apart at a distance from it is roughly the same.Also, for constituting each column with pipe portion 241,243,245
The distance between piping it is roughly the same.Therefore, multiple inner tubes 240 can be configured equably in the supercooling main body
210 inside.
The height of the partition 250, i.e., the height of the slot interconnecting piece 254 be formed as, the supercooling main body 210
Diameter 1/2 or more.If the height of the partition 250 be the supercooling main body 210 diameter 1/2 hereinafter, if it is more
The support force of a inner tube 240, especially secondary series weaken with the support force of pipe portion 243, therefore are preventing the inner tube
It is restricted in terms of 240 vibration.
Therefore, in order to prevent this situation, the height of the partition 250 of the present embodiment, i.e., the height H of slot interconnecting piece 254 can
Be formed as, 1/2 height H1 of the diameter than being equivalent to the supercooling main body 210 is big.
In addition, the partition 250 supports the first row with pipe portion 241 and secondary series with pipe portion 243, and with described the
Three column are spaced with pipe portion 245.That is, the height of the partition 250 is formed in, not inner tube of the support arrangements in highest position
240, i.e., third column with pipe portion 245 multiple pipings height.
As described above, the partition 250 plays the effect for limiting the cutting portion of the flowing of the second refrigerant, because
This, no matter in the case where being configured to divide the inner space of the supercooling main body 210 completely, or is being configured to
In the case that sectional area is excessive, the mobile performance of second refrigerant can all be caused to decline.
As an example, the case where forming partition 250 with the height for the multiple pipings for supporting the third column to match pipe portion 245
Under, in fact it could happen that the too small problem in flowing space portion 218.The flowing space portion 218 is it is understood that in the inner tube 240
Outer space in, the spatial portion of second refrigerant do not cut off by the partition 250, described flowing.
In particular, partition 250 needs to be located at third column piping in order to effectively support the third column with pipe portion 245
More than the height of the central part in portion 245, but in this case, the flowing space portion 218 is too small, leads to second refrigerant
Mobile performance decline.Therefore, in the present embodiment, the height H-shaped of the partition 250 becomes, and is equivalent to the third column and matches
The height H3 or less of the lower end of pipe portion 245.
In addition, the height H of the partition 250 is formed as, it is equivalent to the height of upper end of the secondary series with pipe portion 243
Spend H2 or less.If the height H-shaped of the partition 250 becomes the height H2 or more, the upper-end part of driving of the partition 250 in
Very close third column match the position of pipe portion 245, thus, it is possible to create following problem, that is, in second refrigerant flowing
In the process, the shaking that third column match pipe portion 245 occurs, is thus connect with pipe portion 245 with the partition 250 because of third column
It touches and generates noise.
It also, is the upper end of the partition 250 in the height H of the partition 250 situation identical as the height H2
The case where being formed in the secondary series with the tangent position of pipe portion 243.At this moment, occur being difficult to the partition 250 or
The problem of support slot 253.
Therefore, the height H-shaped of the partition 250 of the present embodiment becomes smaller than the height H2.To sum up, the partition
250 height H is formed as, bigger and smaller than the height H2 than the height H1.For ease of description, the height H1 is known as
The height H2 is known as " the second height " by " the first height ".
In addition, the slot interconnecting piece 254 can be configured such that with third column separated with pipe portion 245 at a distance from be, and it is adjacent
Inner tube 240 between the corresponding value of distance d1 that is separated it is so much.Specifically, it arranges when from the third with pipe portion 245
Match tube hub, with the radius r of setting, define for tangent imaginary concentric of the piping with the secondary series with pipe portion 243
When circle P1, the slot interconnecting piece 254 is configurable on the position tangent with the imaginary concentric circles P1.
Certainly, the height H of the partition 250 or slot interconnecting piece 254 at this moment is formed as, than the first height H1
It is big and smaller than the second height H2.
In other words, the height H-shaped of the partition 250 or slot interconnecting piece 254 becomes, the supercooling main body 210 it is straight
1/2 height H1 or more of diameter, also, the inner tube 240 i.e. secondary series than being supported by the support slot 253 is with pipe portion 243
The height H2 of upper end is small.
According to structure as above, the partition 250 effectively supports multiple inner tubes 240, to have the following advantages that, that is,
The noise that can be prevented the vibration of inner tube 240 and generate by the vibration, can improve the flowing of second refrigerant
Performance and heat exchanger effectiveness.
