Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Embodiment of the present utility model provides a kind of integral type layering Cold Chain Logistics mobile refrigerating case, such as Fig. 1 to Fig. 3 institutes
Show, it includes heat insulation module 10 and cooling assembly 20.
As depicted in figs. 1 and 2, the heat insulation module 10 includes cabinet exterior 101, cabinet wall 102, is arranged at outside casing
Heat-insulation layer 103 between wall 101 and cabinet wall 102 and the insulation separate layer 104 for being arranged on casing stage casing.The insulation point
The casing is divided into top thermal-insulating body 11 and bottom thermal-insulating body 12 by interlayer 104, and the top thermal-insulating body 11 is with
Portion's thermal-insulating body 12 passes through the sealed set of foaming doors 40.
The cooling assembly 20 includes evaporator coil 21, agent for storage of coldness ice chest 22, compressor 23, condenser 24 and fan
25, the evaporator coil 21 turns round from top thermal-insulating body 11 to the Vertical Curve of bottom thermal-insulating body 12 and is fixedly installed on casing
On inwall;The agent for storage of coldness ice chest 22 from top to bottom spiral-lock in the outside of the evaporator coil 21;Wherein, the bottom incubator
The freezing point of agent for storage of coldness ice chest 222 is less than the freezing point of agent for storage of coldness ice chest 221 in the thermal-insulating body of top in body.Preferably, it is described
The freezing point of agent for storage of coldness ice chest 221 is -2 DEG C in the thermal-insulating body of top, the freezing point of agent for storage of coldness ice chest 222 in the thermal-insulating body of bottom
For -25 DEG C.
Specifically, the evaporator coil 21 is fixedly installed on cabinet exterior 101 by fixed fastener 21;The cold-storage
The spiral-lock face of agent ice chest 22 is provided with multiple strip grooves being correspondingly arranged with the evaporator coil 21, the agent for storage of coldness ice chest
22 coordinate spiral-lock on the outside of the evaporator coil 21 by the strip groove, and the evaporator coil 21 and agent for storage of coldness ice
Spacing between box 22 is 0.4-0.6mm, it is preferred that as shown in Fig. 2 being also equipped with being used to protect outside the agent for storage of coldness ice chest 22
The ice chest cover plate 30 of agent for storage of coldness ice chest 22 is protected, avoids agent for storage of coldness ice chest 22 from receiving external force extruding and causes to crush, leak agent for storage of coldness.
The compressor 23, condenser 24 and fan 25 are arranged on bottom half, and are electrically connected with vehicle-mounted computer,
The evaporator coil 21 connects with the compression chamber of compressor 23, the circulation connection of the condensation chamber of condenser 24, and the fan 25 leans on
Nearly condenser 24 is set, for accelerating the radiating efficiency of condenser 24.As shown in figure 1, the both ends of the evaporator coil 21 to
Under extend through tank floor setting, wherein one end is connected by transmission pipeline with the compression chamber of compressor 23, and the other end passes through
Transmission pipeline connects with the condensation chamber of condenser 24.
When needing to freeze to agent for storage of coldness, start compressor 23 and start working, refrigerating medium is freezed, the load
Cryogen is flowed into evaporator coil 21 by kind of refrigeration cycle path, and the agent for storage of coldness in agent for storage of coldness ice chest 22 is freezed, until
The temperature of agent for storage of coldness drops to design temperature.Because the freezing point of agent for storage of coldness ice chest 222 in the thermal-insulating body of bottom is incubated less than top
The freezing point of agent for storage of coldness ice chest 221 in casing, therefore, the temperature of agent for storage of coldness ice chest 221 enters one in the upper back thermal-insulating body that freezes
Step is reduced to -5 DEG C, and the temperature of agent for storage of coldness ice chest 222 is further reduced to -30 DEG C in the thermal-insulating body of bottom.The cooling assembly
20 pairs of agent for storage of coldness ice chests 221 are once freezed, and can make the temperature of top thermal-insulating body in 0 DEG C~5 DEG C sections, the guarantor of bottom
The temperature of incubator body keeps 5-8 hours in -20 DEG C~-18 DEG C sections.
Meanwhile as shown in figure 3, the first temperature is respectively equipped with top thermal-insulating body 11 and bottom thermal-insulating body 12
Spend sensor 111 and second temperature sensor 121, first temperature sensor 111 and second temperature sensor 121 are and car
Computer 50 is carried to communicate to connect.User is set to monitor the temperature in refrigerating box in real time by vehicle-mounted computer, so as to find
When temperature is less than normal temperature, starts cooling assembly 20 in time, the agent for storage of coldness in agent for storage of coldness ice chest 22 is freezed.When first
The temperature that temperature sensor 111 or second temperature sensor 121 sense is higher than threshold temperature, then sends early warning to vehicle-mounted computer
Signal, the vehicle-mounted computer starts compressor 23, condenser 24 and fan 25 after receiving pre-warning signal, to agent for storage of coldness ice chest 22
In agent for storage of coldness freezed, until the temperature that the first temperature sensor 111 or second temperature sensor 121 sense is not higher than
Threshold temperature.
Integral type described in the utility model is layered Cold Chain Logistics mobile refrigerating case, and it is by setting independently sealed set
Top thermal-insulating body 11 and bottom thermal-insulating body 12, and set respectively in top thermal-insulating body 11 and bottom thermal-insulating body 12
The agent for storage of coldness ice chest of different freezing points, realize that upper strata preserves refrigerated item, lower floor preserves the purpose of frozen goods, so as to expand refrigerating box
Preserve food scope, break through existing mounted refrigerating case can only single preservation refrigerated item the defects of, meanwhile, by by cooling assembly 20
It is wholely set with heat insulation module 10, so that the Cold Chain Logistics mobile refrigerating case is being transported for long-distance, can be voluntarily to agent for storage of coldness
Agent for storage of coldness in ice chest 22 is freezed, it is not necessary to which midway, which is stopped, finds external refrigeration unit.
Specific embodiment of the present utility model described above, the restriction to scope of protection of the utility model is not formed.
Any various other corresponding changes and deformation made according to technical concept of the present utility model, should be included in this practicality
