The compressor is connected with condenser, and condenser is connected with device for drying and filtering, and device for drying and filtering is connected with throttling dress
It sets, throttling set is connected with evaporator, and evaporator is connected with gas-liquid separator, and gas-liquid separator is connected with compressor.
Preferably, insulating layer is provided on the outer cover.
Preferably, the refrigerating medium is the mixture of water, alcohol and ethylene glycol, and the freezing point of refrigerating medium is lower than -40 DEG C.
Preferably, outer cover is connected with heat exchanger in case by thermo-insulating pipe line, and cover is outer in or beyond outer cover is provided with circulating pump,
Circulating pump can be sent the refrigerating medium in outer cover into heat exchanger in case by thermo-insulating pipe line.
Preferably, the condenser arrangement has condensation fan.
Preferably, further include circulating fan in case, in case in circulating fan energy accelerating chamber heat exchanger heat exchange efficiency.
There is provided a kind of refrigerating boxes for the second object of the present invention.
A kind of refrigerating box, including cabinet are provided with above-described indirect type refrigeration system on cabinet.
The invention has the advantages that:
Indirect type refrigeration system provided by the invention, cooling capacity caused by evaporator do not enter in refrigerating box, but first
The refrigerating medium that can be circulated is passed to, cooling capacity is transported to heat exchanger in case again by refrigerating medium, by heat exchanger in case to refrigerating box
Cooling, above-mentioned this special structure limit the refrigeration system by production technology when installing, do not need to install in advance
On cabinet, can evacuation, the processes such as be perfused, freeze after the completion of be installed on cabinet body again, refrigeration system may be mounted at cabinet
Bottom, top or other suitable positions, it is in the event of a failure, independently detachable, facilitate maintenance replace.
In addition, the refrigeration system also has unique cool storage function, by circulation pump, compressor operating can make to store
Refrigerant temperature in outer cover persistently reduces, and when opening circulating pump, the low temperature refrigerating medium of storage, which will be transported in case, to be changed
Hot device, cooling effect are more preferable.

Specific embodiment
A specific embodiment of the invention is described further in the following with reference to the drawings and specific embodiments:
Embodiment 1
In conjunction with Fig. 1 to Fig. 2,
Heat exchanger 3 in a kind of indirect type refrigeration system, including compressor 1, refrigerated heat exchanger 2 and case.
Wherein, refrigerated heat exchanger 2 includes outer cover 4, is provided with insulating layer on outer cover.Evaporator 5, outer cover are provided in outer cover
Inside also filled with refrigerating medium 6, evaporator is placed in refrigerating medium.
Evaporator exchanges heat with refrigerating medium, and refrigerating medium is the mixture or other low freezing point liquid of water, alcohol and ethylene glycol
The freezing point of body, refrigerating medium is lower than -40 DEG C.
Heat exchanger is connected with outer cover in case, and the refrigerating medium in outer cover can enter in case in heat exchanger.
Specifically: outer cover is connected with heat exchanger in case by thermo-insulating pipe line, and cover is outer in or beyond outer cover is provided with circulating pump
7, circulating pump can be sent the refrigerating medium in outer cover into heat exchanger in case by thermo-insulating pipe line.
Compressor 1 is connected with condenser 8, and condenser is connected with device for drying and filtering 9, and device for drying and filtering is connected with throttling set
10, throttling set is connected with evaporator 5, and evaporator is connected with gas-liquid separator 11, and gas-liquid separator is connected with compressor.
Specifically, condenser arrangement has condensation fan 12.
There is the refrigerant constantly recycled in these devices, cyclic process is substantially are as follows: the refrigerant of liquid is inhaled in evaporator 5
After the heat for recording cryogen, the steam that part vaporizes journey low-temp low-pressure is sucked by compressor, the liquid refrigerant not vaporized
It is stored in gas-liquid separator 11；It is compressed into after the steam of high pressure-temperature by the gaseous refrigerant that compressor sucks and is discharged into condensation
Device 8 is condensed into highly pressurised liquid within the condenser to air heat release, is the liquid of low-pressure low-temperature through the throttling of throttling set 10, again
The heat vaporization that refrigerating medium is absorbed into evaporator, so recycles.
