Specific implementation mode
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Refering to fig. 1 shown in -4, the cold chain transportation refrigerating box of the invention based on freezing by change of state comprising：
Refrigerated cabinet 1, lower part are equipped with metal partion (metp) 2, and the lower section of metal partion (metp) 2 is equipped with spare interlayer 3, in spare interlayer 3
Equipped with spare hold-over plate 4, the top and bottom of spare interlayer 3 are additionally provided with top placing groove 31 and bottom placing groove 32；
Case lid 5, lid close on refrigerated cabinet 1, and case lid 5 is also connected by lock 6 with refrigerated cabinet 1；And refrigerating box
It is additionally provided with sealing ring between body 1 and case lid 5.Lock 6 and sealing ring can guarantee that case lid 5 is closely connect with refrigerated cabinet 1, close case
When lid 5, lock 6 is closed under external force, and control case lid 5 will not bounce, at this point, sealing ring fills up the gap of junction,
Play adiabatic effect.
Main hold-over plate 7 is arranged in the lower surface of case lid 5, and main hold-over plate 7 includes that cold-storage material fills box 71 and refrigerant 72,
The bottom that cold-storage material fills box 71 is equipped with multiple outwardly projecting cold-storage lattice 73, the inside of cold-storage lattice 73 and cold-storage material filling box 71
It is connected, refrigerant 72 is placed in cold-storage material filling box 71 and cold-storage lattice 73；First, the ice tray shape of cold-storage lattice 73 and tradition
Flat panel contours compare, the charging amount of phase-change material greatly improves, since the cold source of single freezing by change of state only has material
Itself, therefore, the raising of charging amount means that the raising of insulating power；Secondly, the bottom surface area of cold-storage lattice 73 is very big, single
The cold discharged into refrigerated cabinet 1 in the time of position also increases, to make rapid drop in temperature in refrigerated cabinet 1.
Adiabatic pull plate 8 is matched with top placing groove 31 or bottom placing groove 32；
Plug 9 is connected through connecting plate 10 with adiabatic pull plate 8, and plug 9 is also placed with top placing groove 31 or bottom
Slot 32 matches.When that need not use the cold of spare hold-over plate 4, adiabatic pull plate 8 is threaded through in the placing groove 31 of top, is blocked up
First 9 are threaded through in bottom placing groove 32, and spare interlayer 3 is made to be in sealing state, and the cold of spare hold-over plate 4 is avoided to reveal.And
When the temperature in refrigerated cabinet 1, which increases, needs the cold using spare hold-over plate 4, adiabatic pull plate 8 and plug can be extracted out
9, then adiabatic pull plate 8 is worn into bottom placing groove 32, plug 9 is worn into top placing groove 31, makes spare cold-storage
The cold of plate 4 is conducted through metal partion (metp) 2 to refrigerated cabinet 1.
Specifically, refrigerant is the mixed liquor of lauryl alcohol solution and sad solution, the matter of lauryl alcohol solution and sad solution
Amount is than being 35：65.Preferably, refrigerated cabinet 1 and case lid 5 are all made of vacuum heat-insulating plate and are made, the outside of vacuum heat-insulating plate
It is also wrapped on polyurethane material.Vacuum heat-insulating plate has small, light-weight, thermal coefficient low (being less than 0.004w/mk)
Advantage, extraordinary heat insulating function can be played by being combined with polyurethane material, this composite construction and traditional single polyurethane
Material is compared, and heat-insulating property greatly improves, and incubator weight is reduced, free space increases.
As shown in fig.3, when being filled in order to prevent from one end, the special construction of main hold-over plate 7 causes filling incomplete, stores
Cryogen filling box 71 is respectively arranged on the left side and the right side fill port 74, and refrigerant 72 is filled to cold-storage material through fill port 74 and filled in box.
When filling, filled the both ends fill port 74 for filling box 71 since cold-storage material respectively, it is ensured that the charging amount of phase-change material reaches main
The 90% of 7 volume of hold-over plate prevents the volume expansion in freezing of main hold-over plate 7 from causing unnecessary loss.
Preferably, case lid 5 is equipped with handle 11, lifting case lid 5, the outside of connecting plate 10 is facilitated to be additionally provided with draw ring 12, side
Just pull connecting plate 10.
The invention also includes temperature detector and display 13, temperature detector is arranged in the inside of refrigerated cabinet 1, display
Device 13 is arranged in the outer surface of refrigerated cabinet 1, and temperature detector is also connected with display 13.Specifically, temperature detector is real
When refrigerated cabinet 1 in temperature, and be transmitted on display 13, facilitate personnel from external observation.And when temperature in refrigerated cabinet 1
Rise too fast, that is, when being up to limit value, alarm equipment alarm can be triggered, at this moment can extract adiabatic pull plate 8 out, allows spare cold-storage
The cold of plate 4 passes to article by metal partion (metp) 2.
The present invention fills box by being arranged main hold-over plate 7 in the lower surface of case lid 5, and by the cold-storage material of main hold-over plate 7
71 bottom setting is in multiple outwardly projecting cold-storage lattice 73, is freezed to the article in refrigerated cabinet 1 using cold-storage lattice 73
It is refrigerated, and the ice grating texture of cold-storage lattice 73 increases compared to slab construction heat dissipation area, is released in the unit interval
Cold also increases, therefore the temperature in refrigerated cabinet 1 can comparatively fast be reduced to target temperature, and space occupancy rate is low.Meanwhile
When long-distance transport needs to extend the cold preservation time of article, by extracting connecting plate 10 and adiabatic pull plate 8 out, then thermal insulation is taken out
Pulling plate 8 is placed into 32 in the bottom placing groove of spare interlayer 3, and spare hold-over plate 4 continues to discharge enough colds, for continuing to drop
Temperature in low refrigerated cabinet 1 extends cold preservation time.
More than, specific implementation mode only of the invention, but scope of protection of the present invention is not limited thereto, it is any without
The change or replacement that creative work is expected are crossed, should be covered by the protection scope of the present invention.Therefore, protection of the invention
Range should be determined by the scope of protection defined in the claims.
