Description

Portable refrigeration, freshness protection package

The utility model belongs to life appliance, particularly a kind ofly is used to refrigerate, fresh-keeping portable refrigeration, freshness protection package.

At present, it is all the fashion abroad that a kind of small portable is iced hot dual-purpose case, the refrigerator of icing hot dual-purpose case and refrigeration is completely different, adopt conductor refrigeration and pyrogenicity to substitute the compressor freon refrigeration, reduce environmental pollution, good reliability, but the hot dual-purpose case refrigeration of this ice, two kinds of functional structure complexity of pyrogenicity, and be case structure, be not easy to carry.

The purpose that this practicality is newly opened is to overcome above technical deficiency, and a kind of portable refrigeration simple in structure, easy to carry, freshness protection package are provided.

Task of the present utility model is, portable refrigeration, freshness protection package are made up of conductor refrigeration module, regenerator, the temperature controller installed in the complex heat-preservation bag, by the complex heat-preservation bag top that fibre structure and heat-insulation layer are formed installation conductor refrigeration module in handle, the inside and outside carrying plate hole is installed, regenerator, temperature controller and socket, control temperature and grafting transformation rectifier power source.Cooling fluid is housed in the regenerator, and liquid injection port is encapsulated by end cap, in order to avoid excessive.

Portable refrigeration, freshness protection package refrigerating system adopt NP type semiconductor cooling element and connect and form, and non-environmental-pollution is simple in structure; Its two insulated bag adopts multilayer hollow fiber and heat-insulation layer to separate the interlayer setting, has good insulation effect and certain intensity, prevents radiation, conduction.

Embodiment below in conjunction with accompanying drawing specifically describes.

Among Fig. 1,2,3,4,5, portable refrigeration, freshness protection package is made up of semiconductor refrigerating module (4), regenerator (8), the temperature controller (10) installed in the complex heat-preservation bag (3), handle (1) is installed on complex heat-preservation bag (3) top, both sides are installed in inside and outside loading plate (6), (7) hole conductor refrigeration module (4) are installed, and connect regenerator (8), temperature controller (10) and socket (11).Complex heat-preservation bag (3) is made up of 4 layers of doughnut and 3 layers of heat-insulation layer, and the doughnut layer is (17), (19), (21) in proper order, and heat-insulation layer is (16), (18), (20), (3) in proper order.Dress cooling fluid (9) in the regenerator (3).

During use, cooling fluid (9) is packed in (8) regenerator by temperature control mouth (22), reach 4/5 volume number, in order to avoid cooling fluid is freezed, bad regenerator (8) expands.Cooling fluid (9) can be lower than-5 ℃ liquid by ammoniacal liquor, ethanol or other freezing point and make.Cooling fluid (9) and regenerator (8) constitute cold-storage part of the present utility model, constantly absorb heat, keep a bag interior low temperature, refrigeration or fresh-keeping article.

With conductor refrigeration module (4) and temperature controller (10), switch (11), Switching Power Supply (13) order are linked in sequence with lead (12).Conductor refrigeration module (4) adopts high-quality bismuth-antimony-tellurium-selenium solid solution oriented crystal to use the bonding regenerator of heat-conducting silicone grease (8), utilize the thermoelectric cooling principle of (4), select suitable conductor refrigeration module (4), 65 ℃ of the cold and hot surface temperature difference, when environment temperature was 25 ℃, temperature can be reduced to about-10 ℃ in the bag.NP conductor refrigeration module working life can reach hundreds thousand of hours, and temperature controller is chosen in-20 ℃ to the 5 ℃ scopes, has different range shelves, can realize two formula break-make controls to controlled device, realizes refrigeration or fresh-keeping.The required direct current of conductor refrigeration module (4) is provided by (13), and (13) are Switching Power Supply or alternating current-direct current vertoro.(13) go up 2 indicator lamps of installation, demonstration work and halted state.Switch (11) is a plug, in that the time spent is not taken away weight reduction at any time.

Regenerator (8) weight is born in inside and outside loading plate (6), (7), prevents the excessive damage of complex heat-preservation bag (3) local pressure.Inside and outside loading plate is fixing with adiabatic screw (5).

The heat-insulation layer of complex heat-preservation bag is knitted with 3 layers of heat-insulation layer by 4 layers of doughnut and is constituted.(16), (18), (20) are that compound rubber cloth constitutes, and are soft, airtight, high insulating effect.(17), the low doughnut of thermal conductivity or natural fiber-filled is used in (19), (21).Outermost heat-insulation layer (3), the glass or other fiber that use surface vacuum to aluminize are made into radiations heat energy, heat-insulation and heat-preservation.

The utlity model has following features:

1. in light weight, easy to carry, can realize refrigeration, fresh-keeping;
