290 airflow connections that other regions of space 230 are cooled down with goods and materials.The temperature insulating material plate 270 of low-temperature space 290 can not only be consolidated
It is scheduled on the inwall of refrigerator carriage 210, it is also possible to be arranged to mobilizable, dismountable temperature insulating material plate 270.
The hybrid power cold chain transportation car 10 provided by the present invention, can be cooled down by medium cooler 170 and nitrogen
While device 130 freezes to external world, power is exported to vehicle.Can be generated electricity by expansion power generation unit 180 simultaneously, be sent
The electric power equipment that is used directly on automobile, it is also possible to carry out storage for emergency processing.By the He of nitrogen cooler 130
Medium cooler 170 extends cooling flow, can make full use of the low temperature of liquid nitrogen.And the setting of two cooling lines also causes power
Output and electric power output do not interfere with each other.The speed and temperature of refrigeration are can control by the aperture for adjusting valve 111, very just
It is prompt.The discarded object that this liquid nitrogen power output system 100 discharged after power output and electric power output is nitrogen, not to air
Any pollution is caused, meets the requirement of sustainable development.Liquid nitrogen storage tank 110 is arranged on the lower section of refrigerator carriage 210, can be reduced
The center of gravity of hybrid power cold chain transportation car 10, so as to improve the stability of cold chain transportation car.By setting low-temperature space 290, can be with
For special materials provide lower region, the preservation demand of special materials is met.With reference to the law of thermodynamics first, second, from energy
Amount conservation angle analysis, in the entire system, cold is directly or indirectly transfer and increases and decreases, but the electricity that system is obtained
Can be produced with the heat energy that kinetic energy is the goods and materials cooling space 230 absorbed by refrigeration, done using environment thermal energy while refrigeration
Work(, has reached the effect of energy-saving and environmental protection.
The preferred embodiment of the present invention is the foregoing is only, is not intended to limit the invention, for this area
For technical staff, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made it is any
Modification, equivalent, improvement etc., should be included within the scope of the present invention.
