Refrigerant tube 142 can cool down the cold-producing medium of the 1st refrigerant pipe 141 in advance, then again by cooling cold-producing medium to expansion tube 130 row
Go out.
After Filter dryer 130 filters moisture or foreign matter from the cold-producing medium that freezing machine 120 is discharged, then cold-producing medium is provided
The 1st refrigerant pipe 141 to sleeve pipe 140.
Here, the 1st refrigerant pipe 141 in sleeve pipe 140 makes cold-producing medium flow to expansion tube 150 from Filter dryer 130
Dynamic, the 2nd refrigerant pipe 142 makes cold-producing medium flow to compressor 110 from rapid steamer 160.That is, flow in the 1st refrigerant pipe 141
Cold-producing medium and in the 2nd refrigerant pipe 142 flowing cold-producing medium mutually inversely move, by this reverse movement, Ke Yiyou
Effect execution the 1st refrigerant pipe 141 and the heat exchange of the 2nd refrigerant pipe 142.
This sleeve pipe 140 configures behind the back side of shell 103, is molded (molding) by polyurathamc.Foam poly- ammonia
Ester is the resin that a kind of inside carries countless air layers, is coated between refrigerating chamber 101 and body 103, can make according to enforcement

With polyurathamc shaping, on the premise of the thickness that will not make body 103 increases too much, can also be become by polyurathamc
Type is at the back side of body 103.This will describe in detail below.
The cold-producing medium discharged from Filter dryer 130 passes through the 2nd refrigerant pipe in the 1st refrigerant pipe 141 of sleeve pipe 140
After 142 carry out adding cooling, then provide to decompressor 150.In this case, permissible to the cold-producing medium of decompressor 150 applying
It is in by the state of sufficiently over cooling.Supercooled cold-producing medium expands in expansion tube 150, becomes low temperature/low pressure
The cold-producing medium of gaseous state, when it flows into refrigerating chamber 101, it just can drop to sufficiently low temperature.
The latent heat of rapid steamer 160 absorption refrigerating 101 makes cold-producing medium be converted to liquid condition from gas phase.In this situation
Under, rapid steamer 160 has an evaporation tube form in vaporization chamber 101 within for the configuration, the volume of sleeve pipe 140 and the volume of evaporation tube it
Than 1:In the range of 1 or 70%~130%.
Here,
1) volume of evaporation tube refers to the volume calculating on the basis of the internal diameter of evaporation tube;
2) volume of sleeve pipe 140 refers to [volume of volume-the 1 refrigerant pipe 141 of the 2nd refrigerant pipe 142].Below,
[volume of volume-the 1 refrigerant pipe 141 of the 2nd refrigerant pipe 142] is defined as " difference volume ".
In this case, the volume of the 2nd refrigerant pipe 142 corresponds on the basis of the internal diameter of the 2nd refrigerant pipe 142
Volume, and the volume of the 1st refrigerant pipe 141 corresponds to the volume on the basis of the external diameter of the 1st refrigerant pipe 141.
Here, the volume of the 2nd refrigerant pipe 142 purely refers to that cold-producing medium can flow in the inside of the 2nd refrigerant pipe 142
Dynamic internal volume.
When allosome of being on duty amasss=evaporate pipe volume, the cold-producing medium discharged to compressor 110 from evaporation tube will be from filtration drying
Device 130 flows to the liquid refrigerant cooling of expansion tube 150, is flowed to from Filter dryer 130 by the 1st refrigerant pipe 141 and expands

Calculate, you can be calculated according to " 12.25 Π x h ".
In this case, the volume of the 1st refrigerant pipe 141 is " 4 Π x h ", and the volume of the 2nd refrigerant pipe 142 is permissible
Calculated according to " 16 Π x h ", difference volume can be calculated according to " 16 Π x h " " 4 Π x h "=" 12 Π x h ".
If it is assumed that the equal length of the length of evaporation tube and the 2nd refrigerant pipe 142, then with respect to the 2nd cold-producing medium of evaporation pipe volume
The volume ratio of pipe 142 (or the 1st refrigerant pipe 141) is calculated as 12/12.5=96%.
In addition, when the evaporation pipe volume being determined by described volume ratio and the 2nd refrigerant pipe 142 (or the 1st refrigerant pipe 141)
Volume close when, to expansion tube 150 flow into refrigerant temperature rise in the presence of the 1st refrigerant pipe 141, by the 2nd
Refrigerant pipe 142 declines to the refrigerant temperature that compressor 110 flows from evaporation tube.In this course, with expansion tube 150
The expansion temperature difference (Δ T) of the temperature difference definition between the outside air temperature of the refrigerant temperature of interior expansion and refrigerating chamber 101 declines.
Expand the temperature difference (Δ T) decline make the refrigerant temperature in evaporation Bottomhole pressure be unlikely to be reduced to -100 DEG C with
Under, the temperature of cold-producing medium can be made to reach -70 DEG C~-80 DEG C.That is, can be rapidly reached according to the superfreeze storehouse of embodiment
