Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: ice chest 1, certainly pressurization liquid nitrogen container 2, cold nitrogen supply (NS) unit 3, defrosting system 4, solenoid valve 5, the first thermometer
6.1, second temperature meter 6.2, heating sheet 7.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments:
As shown in Figure 1, the cold-chain box based on liquid nitrogen cold-storage and spray cooling of the utility model, including ice chest 1, pressurization certainly
Liquid nitrogen container 2, multiple cold nitrogen supply (NS) units 3, multiple defrosting systems 4 and control system 8.The ice chest 1 uses thermal insulation material, tool
There is good insulation capacity.The multiple cold nitrogen supply (NS) unit 3 further includes solenoid valve 5, the first thermometer 6.1, component
Between pass through pipeline be welded to connect；Wherein the first thermometer 6.1 is placed in corresponding magazine for detecting cargo temperature；It is described
Multiple defrosting systems 4 further include heating sheet 7 and second temperature meter 6.2；Wherein second temperature meter 6.2 and heating sheet 7 are installed in
Nozzle.
Certainly the pressurization liquid nitrogen container 2, which can be connected through a screw thread to be fixedly placed in or beyond ice chest 1, to be hung on outside ice chest 1；From increasing
Pressure liquid nitrogen container 2 is connected to injection general pipeline, and injection general pipeline is divided into multiple cold nitrogen supply (NS) units 3 being connected in parallel；Each cold nitrogen supplies
Unit 3 is answered to use piping connection spout, spout can adjust direction position；Wherein, the line end of each cold nitrogen supply (NS) unit 3
