Abstract
The invention discloses a refrigerating transport box with the cold recovering function. Cold steam exhausted from a refrigerating compartment can be made to circulate outside the compartment, the heat directly absorbed by the compartment from the outside is reduced, energy sources are saved, and time for refrigeration is long. A refrigerant storing space is reserved at the top of the refrigerating compartment. A refrigerant outlet is formed in the refrigerant storing space. Outer compartment plates are arranged on the outer periphery and the top of the refrigerating compartment. A cold air channel with the periphery and the top communicated is formed between the outer compartment plates and the refrigerating compartment. A bottom air inlet communicated with the cold air channel is formed in the bottom of the refrigerating compartment. A top exhaust port is formed in the top of the cold air channel to form the chimney effect. The cold steam generated in the refrigerating compartment enters the cold air channel of the periphery of the refrigerating compartment through the bottom air inlet from the bottom of the refrigerating compartment, absorbs the heat of the outer compartment plates and then is exhausted from the top exhaust port. The heat absorbed by the refrigerating compartment from the outside is reduced, the amount of adopted low-temperature liquid or solid can be reduced, energy sources are saved, and the time for refrigerating is long.

Utilize the refrigerating transport vehicle of cryogenic liquid or solid evaporation in transportation, produce steam after cryogenic liquid or Solid endothermic evaporation, the temperature of this steam is identical with the temperature in envelope, belongs to low temperature cold steam.Along with the prolongation of haulage time, the increasing pressure in transport envelope is high.If exceed safe pressure, then accident can be produced.If the cold steam that these temperature are lower is directly discharged, also result in waste.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of refrigerated transport case with cold recovery function is provided, the cold steam of discharging in refrigeration envelope can be made in envelope outer loop, decrease the heat that envelope directly absorbs from outside, the energy-conservation energy, the cold insulation time is long.
The technical scheme adopted for realizing object of the present invention is:
Have a refrigerated transport case for cold recovery function, comprise refrigeration envelope, the top of described refrigeration envelope is provided with refrigerant storage space, and described refrigerant storage space is provided with refrigerant exit; Described refrigerating carriage external body surrounding and top are provided with external carriage board, the cold air channel that surrounding and top are communicated with is formed between described external carriage board with described refrigeration envelope, the bottom air inlet be communicated with described cold air channel is provided with bottom described refrigeration envelope, the top of described cold air channel is provided with top exhausr port, forms chimney effect; The cold steam that described refrigeration envelope inside produces by bottom described refrigeration envelope in the cold air channel that described bottom air inlet enters described refrigeration envelope surrounding, absorb the heat of described external carriage board, then discharged by top exhausr port.
Described external carriage board is reflector.
Distance between described external carriage board and described refrigeration envelope is 1-3cm.
Described refrigerant is cryogenic liquid or solid, as liquid nitrogen or dry ice.
Described bottom air inlet is arranged at the rear portion of the described refrigeration envelope away from cabin door, and described top exhausr port is arranged at the top near described cabin door.
Compared with prior art, the invention has the beneficial effects as follows:
1, the low temperature cold steam that refrigerated transport case of the present invention produces after utilizing cryogenic liquid or Solid endothermic evaporation plays insulation effect to refrigeration envelope, decrease the caloric receptivity of refrigeration envelope from the external world, thus the use amount of cryogenic liquid or solid can be reduced, saved the energy, the cold insulation time is long.Meanwhile, to avoid refrigerating in envelope because cold steam increases the phenomenon that build-up of pressure raises, ensured the safety of transport.
2, in refrigerated transport case of the present invention, the discharge of cold steam make use of chimney effect, does not need blower fan, decreases energy consumption.
3, the external carriage board of refrigerated transport case of the present invention adopts reflector, can reduce the radiant heat that refrigerating carriage is external.
4, refrigerated transport case cryogenic liquid of the present invention or solid storage space are in refrigerated transport box top, improve the utilization ratio of refrigerated transport case.
5, in refrigerated transport case of the present invention, the distance between external carriage board and refrigeration envelope is 1-3cm, and also namely the distance of cold air channel, between 1 to 3cm, prevents the air-flow velocity that air is larger.
Accompanying drawing explanation
Figure 1 shows that the present invention has the structural representation of the refrigerated transport case of cold recovery function.
In figure: 1. external carriage board, 2. cold air channel, 3. refrigerate envelope, 4. bottom air inlet, 5. refrigerant storage space, 6. refrigerant exit, 7. push up exhausr port, 8. cabin door.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The present invention has the schematic diagram of the refrigerated transport case of cold recovery function as shown in Figure 1, and comprise refrigeration envelope 3, the top of described refrigeration envelope 3 is provided with refrigerant storage space 5, and described refrigerant storage space 5 is provided with refrigerant exit 6.The outside surrounding of described refrigeration envelope 3 and top are provided with external carriage board 1, the cold air channel 2 that surrounding and top are communicated with is formed between described external carriage board 1 with described refrigeration envelope 3, the bottom air inlet 4 be communicated with described cold air channel 2 is provided with bottom described refrigeration envelope 3, the top of described cold air channel 2 is provided with top exhausr port 7, forms chimney effect.In the present embodiment, described bottom air inlet 4 is arranged at the rear portion of the described refrigeration envelope 3 away from cabin door 8, and described top exhausr port 7 is arranged at the top near described cabin door 8.The cold steam that described refrigeration envelope 3 inside produces by bottom described refrigeration envelope in the cold air channel 2 that described bottom air inlet 4 enters described refrigeration envelope surrounding, absorb the heat of described external carriage board 1, then discharged by top exhausr port 7.
