Description
Technical field:
The utility model relates to a kind of Portable low-temp cold storage plant, be refrigerated transport and the low tempertaure storage device of reagent, medicine box and the vaccine required for biomedicine, clinical medicine, inspection and quarantine, vaccination and scientific research, belong to biomedical, clinical medicine and scientific research equipment technical field.
Background technology:
So-called low temperature, refers to that ambient air temperature is boundary lower than 10 DEG C.Reagent and vaccine are the important materials of biomedicine, clinical medicine, prevention and health care and inspection and quarantine, and the storage of science is the key link of guaranteeing reagent and vaccine quality safety.Within the scope of temperature-5 DEG C～10 DEG C, histocyte metabolism, in dormant state, is the key point that maintains cellular morphology structure " virgin state ".Because water is the density maximum of 4 DEG C, some titers, as the storage temperature of sulfate standard solution, nitrite standard solution, nitrate standard solution, fluorine standard solution, chlorine standard solution, phosphorus standard solution, copper, iron, calcium, magnesium, sodium standard solution is made as 5 DEG C of conditions, otherwise affect " normal concentration " of standard solution.The technique of refrigeration adopting at present mainly comprises:
1. freon refrigeration: while adopting freon refrigeration, both can cause atmospheric pollution to have the human health of being unfavorable for owing to discharging chemical substance in process of refrigerastion.
2. tetrafluoro hexane (R-134a) refrigeration: being also referred to as floride-free refrigeration, is a kind of refrigeration mode with R-134a or R600A replacement fluorine Leon, can not produce the objectionable impurities of atmosphere pollution.But because needing compressor, floride-free refrigeration mode could work.Relatively other refrigerant, that the technical matters of R600a refrigeration requires is high, investment is large, cost is high.
3. carbon dioxide dry ice refrigeration: adopting refrigeration reagent or the medicine box of carbon dioxide dry ice, is current the most frequently used method.But because carbon dioxide dry ice is volatile, be unfavorable for effective preservation of reagent or medicine box.
4. semiconductor refrigerating: semiconductor refrigerating is also thermoelectric cooling is the Peltier effect of utilizing semi-conducting material.In the time of galvanic couple that direct current (DC) is connected into by two kinds of different semi-conducting materials, can absorb respectively heat at the two ends of galvanic couple and emit heat the object that has reached refrigeration.Be characterized in movement-less part, reliability is high.There is very high practical value.
The deficiency that lacks low tempertaure storage equipment for overcoming reagent or vaccine low tempertaure storage inconvenience transport or basic health mechanism, improves the safe and effective of reagent and vaccine quality, and the utility model is provided.By literature search, have no the open report identical with the utility model.
Summary of the invention:
The purpose of this utility model is overcoming the deficiency of prior art, and provides a kind of for improving the Portable low-temp cold storage plant of reagent or vaccine low tempertaure storage quality.
Portable low-temp cold storage plant of the present utility model, is made up of casing and refrigeration parts; Wherein: refrigeration parts are by reefer (6), be placed in source of AC and the storage battery (1) of reefer (6) one end, be placed in the aluminum alloy heat radiation layer (2) of reefer (6) outside face, be placed in aluminum alloy heat radiation layer (2) outside face radiating gill (3) and radiator (4), be placed in reefer (6) other end aluminum alloy heat-conducting layer (7), be placed in secondary semiconductor chilling plate (5) on aluminum alloy heat-conducting layer (7) composition; On one side of casing, have the interface that has power lead (9) on exhaust outlet (8), another side.
The material that parts of the present utility model adopt market to buy product or market purchase is prepared according to a conventional method.
The utility model has the advantage of:
1, rational in infrastructure, volume is little, lightweight, pollution-free, consume energy little, refrigeration cost lower.
2, adopt secondary refrigeration can improve refrigerating speed and refrigeration, be conducive to reagent or medicine box and enter fast frozen state, thereby the reliability of guaranteeing medical experiment or clinical detection result, reduces testing cost simultaneously, improve the science of medical research, clinical examination and scientific experiment
3, range of use is wide, is not only applicable to all kinds of colleges and universities, scientific research institution and basic health mechanism transport reagent or vaccine, is particularly useful for basic health mechanism storage vaccine.

Fig. 1 is refrigeration block construction schematic diagram of the present utility model.
Fig. 2 is the structural representation of the utility model embodiment.
Detailed description of the invention:
Portable low-temp cold storage plant of the present utility model, is made up of casing and refrigeration parts; Wherein: refrigeration parts are by reefer 6, be placed in source of AC and the storage battery 1 of reefer 6 one end, be placed in the aluminum alloy heat radiation layer 2 of reefer 6 outside faces, be placed in radiating gill 3 and the radiator 4 of aluminum alloy heat radiation layer 2 outside faces, the aluminum alloy heat-conducting layer 7 that is placed in reefer 6 other ends, the secondary semiconductor chilling plate 5 being placed on aluminum alloy heat-conducting layer 7 and form; On one side of casing, have the interface that has power lead 9 on exhaust outlet 8, another side.
The material that parts of the present utility model adopt market to buy product or market purchase is prepared according to a conventional method.
When use: open Box Cover, the object of needs refrigeration is put into casing, put down Box Cover, this device that switches on power is started working.When use, note: the direct supply voltage and current of use must not exceed the rated current of assembly; Must not moment when refrigeration work logical reverse voltage (must after 5 minutes).
Practical application shows, the utility model reaches designing requirement completely.
