Abstract

The utility model relates to a small refrigerator which is characterized in that the refrigerator comprises a box body and a box lid, the box body and the box lid have a double-layer structure respectively, wherein the outer layer is a protective layer, and the inner layer is an insulating layer; partition boards are arranged in the box body, the partition boards are closed in a circle and separate the space inside the box body into an outer cavity and an inner cavity, and the partition boards are provided with a plurality of riser vents. The small refrigerator has the advantages of simple structure, convenient and practical use and good heat insulation effect. When the refrigerator is used, dry ice is placed in the outer cavity of the box body, the things to be refrigerated are placed inthe inner cavity, the dry ice gasifies and absorbs heat to lower the box temperature, and the riser vents on the partition boards result in basically consistent temperature between the inner cavity and the outer cavity. The small refrigerator can maintain inside temperature lower than -20 DEG C within 24 hours even in summer heat, so as to basically meet the needs of general enterprises for the transport of biological products. The small refrigerator can save a lot of transportation cost compared with the existing mode of transport.

Description

Small-sized refrigeration insulation can

Technical field:

The utility model relates to a kind of insulation can, particularly a kind of small-sized refrigeration insulation can that is used for temporarily depositing biopreparate.

Background technology:

At present, some biopreparates or its raw materials for production all need to keep low temperature in transportation, as are used for the raw blood plasma that blood product is produced, and the elementary centrifugalization product-cryoprecipitate of raw blood plasma, the temperature in its transportation all must not be higher than-20 ℃.At present, all there is extremely exacting requirements in state food Surveillance Authority to the transportation of these article, usually, all is to use the van cooler that has the automatic temperature-adjusting recording device to transport.But because the tonnage of present this van cooler is bigger,, can cause very big waste, cost of product is raise for a spot of transportation.

Summary of the invention:

The purpose of this utility model is a kind of small-sized deep freezer of design, is used for article in the guard box to keep the low temperature stipulated in the regular hour.

The realization the technical solution of the utility model is, a kind of small-sized refrigeration insulation can is characterized in that insulation can comprises casing and case lid, and casing and case lid are double-decker, and skin is a protective layer, and internal layer is a heat-insulation layer; Be provided with dividing plate in the described casing, dividing plate forms a circle and is closure state, and the space in the casing is divided into exocoel and inner chamber, has several breather holes on the dividing plate.

The utility model has the advantages that, simple in structure, convenient and practical, high insulating effect during use, is placed dry ice in the exocoel of casing, place the article that need refrigeration in the inner chamber, the setting of dividing plate makes not direct contact chilled goods of dry ice, guarantees that the temperature of chilled goods is more even, does not have local undercooling point.The dry ice gasification absorbs heat and reduces the temperature inside the box, and the breather hole on the dividing plate is consistent the temperature of inner chamber and exocoel substantially.Even the temperature that the utility model in the heat in summer, also can be kept in the case was lower than-20 ℃ in 24 hours, can satisfy the requirement of general enterprise transportation biological products basically.Compare with existing transportation mode, can save the mass transportation expense.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Number in the figure: 1 casing, 2 case lids, 3 inner chambers, 4 exocoels, 5 steps, 6 heat-insulation layers, 7 breather holes, 8 dividing plates.

The specific embodiment:

Referring to Fig. 1, Fig. 2, the junction of described casing 1 and case lid 2 is the step 5 formula combinations that concave, convex interlaces, and makes casing 1 and case lid 2 airtight and better heat preservation; The material of described heat-insulation layer 6 is a polyurethane foam plastics, and the material of described dividing plate 8 is a common plastics, and the breather hole 7 on the dividing plate is a through hole, and the air of inner chamber 3 and exocoel 4 is communicated, and guarantees the consistent as far as possible of the temperature inside the box; Casing 1 and case lid 2 are separate type, by snap close the two are fixed together during use; Usually, being placed on the interior dry ice of deep freezer and the ratio of chilled goods is 1: 1, under this ratio, when ambient temperature is 37 ℃,-20 ℃ temperature can be kept more than 24 hours in the case, different according to ambient temperature, haulage time and conveying objects can suitably be adjusted dry ice and chilled goods and place what ratio.
