Summary of the invention
The purpose of this utility model provides the multistage thermoelectric refrigerator of a kind of split.It had both kept the effective advantage of integral structure by the split structure, and it is little to have taken into account the use partial volume again, and the restrictive conditions such as no dry sound of working make final step obtain lower cold junction temperature and big refrigerating capacity.
In order to solve the problem of above-mentioned technology, the utility model is achieved through the following technical solutions: the multistage thermoelectric refrigerator of split, each thermoelectric refrigerator has cold junction and hot junction, it is made of the thermoelectric refrigerator of multi-stage separation, each grade has the refrigeration unit of an independent completion of one's own, for dividing body structure, each unit is connected in series by pipeline between previous stage thermoelectric refrigerator and the back one-level; The previous stage low-temperature receiver communicates with back one-level thermal source.
The utility model also can be achieved through the following technical solutions: the cold of described previous stage thermoelectric cooling unit flows to the hot junction of one-level thermoelectric cooling unit, back by pipeline, working medium by metal medium or power set.
The utility model also can be achieved through the following technical solutions: described power set are liquid pump.
The utility model also can be achieved through the following technical solutions: hot junction one side of described first order thermoelectric refrigerator fits in the cold junction of heat transmission gas; This hot junction side in addition is attached on the cooling box of metal medium or interior dress working medium, and the liquid box of fitting in later thermoelectric refrigerators at different levels hot junction communicates by working medium with the previous stage cooling box.Also can be that each cold and hot end links to each other by metal medium.
The utility model also can be achieved through the following technical solutions: the cold junction of described terminal temperature difference electricity refrigerator connects cold cap.
The utility model also can be achieved through the following technical solutions: the cold junction of described terminal temperature difference electricity refrigerator connects cold blanket.
Compared with prior art, the beneficial effects of the utility model are: the multistage thermoelectric refrigerator of the split of this refrigerator, owing to adopt to divide a body structure, so can in main part, use blower fan to force heat radiation to reach freezing capacity height, purpose that refrigerating capacity is big.Because adopting, main part and use part divide body structure, only depend on pipeline to connect, so the dry sound that can make blower fan generation in the main part is away from using part, and owing to use part actual what adopt is the liquid cools mode, therefore can will use partial design become that volume is little, the thermoelectric cooling device of no dry sound, aforesaid the deficiencies in the prior art have well been solved, for the new world has been opened up in the application of thermoelectric refrigerator again.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: please refer to Fig. 1, the utility model is a kind of split thermoelectric cooling device, the multistage thermoelectric refrigerator of a kind of split, each thermoelectric refrigerator has cold junction and hot junction, it is made of the thermoelectric refrigerator of multi-stage separation, each grade has the refrigeration unit of an independent completion of one's own, and for dividing body structure, each unit is connected in series by pipeline between previous stage thermoelectric refrigerator and the back one-level; Previous stage low-temperature receiver and back one-level thermal source communicate.The cold of previous stage thermoelectric (al) cooling unit flows to the hot junction of one-level thermoelectric cooling unit, back by pipeline, working medium by metal medium or power set.Power set are liquid pump.Hot junction one side of first order thermoelectric refrigerator 3 fits in the cold junction of radiator 2, this hot junction side in addition is attached on the cooling box 4 of metal medium or interior dress working medium, the liquid box of fitting in later thermoelectric refrigerators at different levels hot junction and previous stage cooling box 4 communicate by working medium, also can be that each cold and hot end is continuous by metal medium.
In the described embodiment of Fig. 2, the cold junction of described terminal temperature difference electricity refrigerator connects cold cap.
In the described embodiment of Fig. 3, the cold junction of described terminal temperature difference electricity refrigerator connects cold blanket.
In the described embodiment of Fig. 1, its technical scheme mainly comprises: by main body thermoelectric cooling multistage independent one or that split constitutes part (contain radiator 2, thermoelectric refrigerator 3. liquid storage box 4, circulating line 5, power circulating device 6, metal medium 8 and control system 9) and by thermoelectric refrigerator 3. the terminal use part that liquid storage box 4, circulating line 5, cooled object 7 are formed.Two parts connect by pipeline, its operation principle is as follows: main part adopts the integrated high-efficiency refrigerator of prior art, radiator 2 can be heat pipe or fin, needle-like, finger-inserting type, riveting formula radiator expands, owing to adopt the split design, so can in main part, use blower fan to force heat radiation to reach refrigerating efficiency height, purpose that refrigerating capacity is big.Main part also can be taked multi-stag multi-disc thermoelectric cooling mode, progression is determined according to specific requirement, the thermoelectric refrigerator cool and heat ends is connected as a single entity by metal medium or working medium circulating line in the multistage mode, the cold that previous stage thermoelectric refrigerator cooler produces is used for back one-level thermoelectric refrigerator cooler hot-side heat dissipation, by control circuit control thermoelectric refrigerator cooler duty, guarantee cold and back one-level heat exchange heat coupling that previous stage produces.The cold that main part produces is transferred to the liquid box that links to each other with its use part hot junction by working medium in the circulating line 5 and liquid pump 6, finishes exchange heat at this, thereby meets design requirement.Because main part and use part adopt the split design, only depend on pipeline to connect, so the dry sound that can make blower fan generation in the main part is away from using part, and owing to use part actual what adopt is the liquid cools mode, therefore use portion can be designed to that volume is little, the thermoelectric cooling device of no dry sound, well solved the deficiency of aforementioned prior art, for new scope has been opened up in the application of thermoelectric refrigerator.
