Send out pasting position and being adjusted according to actual needs of pipe 40, in addition described second evaporation tube 40 can be configured as being embedded in
The inflation type of described freezing inner bag 20 rear wall 23 upside.
At present, heat transfer has 3 kinds of basic modes: heat conduction, heat convection, radiation heat transfer.Wherein capacity of heat transmission heat conductivity
To weigh, and heat conductivity itself and the relating to parameters such as material, density, water capacity, temperature.The described freezing inner bag 20 of the present invention
On be provided with heat exchange zone, and in described heat exchange zone, include at least two heat transfer coefficients.Described heat exchange in the present invention
Area has two kinds of embodiments, below this two kinds of embodiments will be described in detail respectively.
Embodiment one, described first evaporation tube 30 and described second evaporation tube 40 are arranged in described heat exchange zone,
And described second evaporation tube 40 has the material of high thermal conductivity coefficient, so that the heat transfer coefficient of described second evaporation tube 40 is higher than institute
State the heat transfer coefficient of freezing other positions indoor (including described freezing inner bag 20 and described first evaporation tube 30), thus described the
The temperature on two evaporation tube 40 surface can be less than the temperature at described freezing other positions indoor and then damp and hot within described refrigerating chamber
Air can be in the preferential frosting in position of corresponding described second evaporation tube 40.Specifically, the material of described first evaporation tube 30 is
Aluminum, described second evaporation tube 40 includes aluminum pipe and is formed at the copper coating of aluminum tube surfaces, thus the biography of described second evaporation tube 40
Hot coefficient is higher than the heat transfer coefficient of described first evaporation tube 30.
Embodiment two, described second evaporation tube 40 are arranged in described heat exchange zone, and described second evaporation tube 40 wraps
Include the first evaporation part and the second evaporation part being connected with described first evaporation part.Described second evaporation part has high thermal conductivity coefficient
Material so that the heat transfer coefficient of described second evaporation part be higher than described first evaporation part and described freezing interior other positions
The heat transfer coefficient of (including described freezing inner bag 20 and described first evaporation tube 30), thus the temperature on described second evaporation part surface
Can be less than the temperature at described freezing other positions indoor, and then the damp-heat air within described refrigerating chamber can be corresponding described second
The preferential frosting in position of evaporation part.Specifically, the material of described first evaporation part is aluminum, and described second evaporation part includes aluminum pipe
With the copper coating being formed at aluminum tube surfaces, thus the heat transfer coefficient of described second evaporation part be higher than described first evaporation part heat transfer
Coefficient.
And then, in refrigeration, it is right that the damp-heat air within described refrigerating chamber can be preferentially accumulated in the direct cooling refrigerator of the present invention
Should the higher position of heat transfer coefficient in this position frosting in described heat exchange zone, decrease described freezing other positions indoor
Frosting degree, has reached the effect luring frost, has also reached the purpose of energy-conservation.
Described cold room includes being arranged on the cold preservation inner bag (not shown) of described cooling compartment and in described cold preservation
The 3rd evaporation tube 11 and the 4th evaporation tube 12 that gallbladder is freezed.In present embodiment, described 3rd evaporation tube 11 and described
Four evaporation tubes 12 are aluminum pipe, and described 3rd evaporation tube 11 and described 4th evaporation tube 12 be all covered in band-tube type described cold
Hide on inner bag；And in other embodiments, described 3rd evaporation tube 11 and described 4th evaporation tube 12 can be configured as embedding
Inflation type in described cold preservation inner bag.
Described first evaporation tube 30, described second evaporation tube 40, described 3rd evaporation tube 11, described 4th evaporation tube 12 and
Described energy-conservation part 4 jointly connects combination and forms an evaporation tube group.
Described 3rd evaporation tube 11 is arranged between described compressor and described second evaporation tube 40 so that cold-producing medium from
Compressor outlet first flows through described 3rd evaporation tube 11 and flows to described second evaporation tube 40 again.
It is additionally provided with muffler 50, so that cold-producing medium is from the first steaming between described first evaporation tube 30 and described compressor
Send out pipe 30 outlet 31 first to flow through described muffler 50 and flow to described compressor again.In present embodiment, described muffler 50 is in s type
It is arranged on the side of described freezing inner bag 20, and in other embodiments, described muffler 50 also can linear or spiral
Shape or other shapes are arranged on the described side freezing inner bag 20.
Described 4th evaporation tube 12 is arranged between described first evaporation tube 30 and described muffler 50, so that cold-producing medium
First flow through described 4th evaporation tube 12 from the first evaporation tube 30 outlet 31 and flow to described muffler 50 again.
So, when cooling cycle system normally runs, cold-producing medium is from compressor outlet first for the direct cooling refrigerator of the present invention
Flow out and flow into described 3rd evaporation tube 11, then flow into described second evaporation tube 40 again, then flow into described first evaporation again
Pipe 30, followed by cold-producing medium first flows into described 4th evaporation tube 12 after described first evaporation tube 30 outlet 31 is flowed out and passes through
Described muffler 50, finally flows back in described compressor, so that next time recycles.
Define in the direct cooling refrigerator casing of the present invention one from back to front, top-down temperature field, hence into arriving
Damp-heat air within described refrigerator body can be in Automatic Cycle in the presence of said temperature field to corresponding described heat exchange zone
The higher position of heat transfer coefficient and preferential in this position frosting, with further such that indoor its in addition to this position of described freezing
The frosting degree at his position reduces, and then controls the position of the indoor frosting of described direct cooling refrigerator freezing, serves the effect of energy-conservation.
In sum, the direct cooling refrigerator of the present invention passes through setting heat exchange zone and evaporation tube on described freezing inner bag 20
Group, and in described heat exchange zone, described evaporation tube group has at least two heat transfer coefficients, thus wet within described refrigerating chamber
Hot-air can arrive the higher position of heat transfer coefficient in this portion in the described heat exchange zone of correspondence with the vortex preferential build in temperature field
Position frosting, thus the frosting degree not only achieving while cooling system performance reaches requirement within refrigerating chamber significantly reduces,
Frosting position has obtained effective control, also acts the effect of energy-conservation simultaneously.
Above example only in order to technical scheme to be described and unrestricted, although with reference to preferred embodiment to this
Bright be described in detail, it will be understood by those within the art that, technical scheme can be modified
Or equivalent, without deviating from the spirit and scope of technical solution of the present invention.
