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.
Fig. 1 is according to the split type blood plasma quick freezer schematic diagram constructed by the utility model, as shown in figure 1, instant freezer is adopted
With split-type design, including two parts of indoor set and outdoor unit, outdoor unit includes double-stage compressor 1, condenser 2, reservoir
2nd, cooler 5, drier 4, filter 6, choke valve 7, gas-liquid separator 16, pressure-regulating valve 17, indoor set steam including flat board
Device 9, expansion valve 8, flexible steel in flat section tubing 10, temperature-sensitive bag 13 are sent out, indoor set is connected with outdoor unit by connection valve 15 with pipeline 14.
The course of work of component above will be illustrated below：
Power-on, system starts, low-temperature low-pressure refrigerant go out from the upper and lower cold drawing 11,12 of plate evaporator
Come, after piping 14, connection valve 15, gas-liquid separator 16 and pressure-regulating valve 17, into low-pressure stage compresser cylinder 18
Interior, refrigerant pressure temperature raises after compression, subsequently into second compression, pressure enter one with temperature again in high pressure stage compressor 19
Step rise turns into high-temperature high-pressure refrigerant steam, subsequently enters in condenser 2, the refrigerant vapour of HTHP is relative with temperature
Refrigerant temperature reduces after relatively low air carries out heat exchange, so as to be condensed into high pressure liquid refrigerant, then by liquid storage
After device 3 adjusts the amount of refrigerant, dried in drier 4, now refrigerant is divided into two parts, is partly into cooler 5
Interior conduit, another part refrigerant throttle decrease temperature and pressure after the filtering of filter 6, then through choke valve 7, turn into the system of medium temperature and medium pressure
Cryogen, then enter back into the Outer Tube of cooler 5, the medium temperature and medium pressure refrigerant in Outer Tube and the HTHP in interior conduit
Refrigerant vapour carries out heat exchange, and so as to reduce the refrigerant temperature in interior conduit, then the refrigerant in Outer Tube is from cold
But compressor 1 is flowed out in device 5, and is mixed with the refrigerant in low-pressure stage compressor 18, the refrigerant in interior conduit is from cooling
After device 5 comes out, reach expansion valve 8 by connection valve 15, the decrease temperature and pressure that throttled in expansion valve 8 turns into low-temp low-pressure liquid refrigeration
Agent, the heat absorbed in plate evaporator 11,12 in blood plasma is finally entered, so that blood plasma is frozen.
The sound sent when because of the noise main source of instant freezer being compressor operation, and the utility model is using split type
Design, when system works, because compressor is installed outdoors, therefore room noise very little, so as to greatly improve blood station personnel
Working environment.And condenser is also mounted at outdoor by split-type design so that the main heat sink of equipment is in outdoor, so that not
The temperature of interior can be influenceed, and does not also interfere with the normal operation of the indoor miscellaneous equipment more sensitive to temperature.General speed
The working environment of jelly machine is -20 DEG C~45 DEG C, if when all-in-one indoor environment is more than 35 DEG C, in order to ensure that it can be good
Run on ground, it is necessary to air-conditioning is opened, and the utility model is installed outdoors by condenser using split-type design, runtime system production
Raw heat discharges in time so that indoor quantity of heat production is less and heat will not also be accumulated indoors, and indoor temperature will not
It is continuous to rise, therefore air-conditioning can need not be opened, so as to reduce energy consumption, improve efficiency.Split-type design is divided into indoor set and room
Outer machine, outdoor unit is installed outdoors, only indoor set installation is placed indoors, reduces the interior room space-consuming of equipment.
In addition, the upper cold drawing 11 of flat-plate evaporators is connected with the lower cold drawing 12 of flat-plate evaporators by flexible steel in flat section tubing 10
And upper and lower cold drawing may move.During frozen plasma, using the direct thermal contact conductance of compression type, upper and lower cold drawing clamps plasma bags, this
The design of sample reduces thermal resistance, increases heat transfer contact area, so as to accelerate plasma freezing speed.
As it will be easily appreciated by one skilled in the art that preferred embodiment of the present utility model is the foregoing is only, not
To limit the utility model, any modification of all made within spirit of the present utility model and principle, equivalent substitution and change
Enter, should be included within the scope of protection of the utility model.
