Abstract

The utility model relates to a novel food freshness keeping box. The novel food freshness keeping box comprises an outer box body, a thermal insulation and heat preservation layer, a thermal insulation vacuum layer, a plurality of heat pipes and an inner box body. The inner box body is arranged in the middle of the outer box body. The thermal insulation and heat preservation layer, the thermal insulation vacuum layer and the heat pipes are sequentially arranged between the outer box body and the inner box body. The heat pipes are arranged on the periphery of the inner box body, and each heat pipe penetrates out of the upper portion of the inner box body, is firmly attached to the outer side of the inner box body in an air-tight mode and is perpendicular to the bottom of the inner box body. A heat pipe technology is introduced, one end of each heat pipe is an evaporation end, the other end of each heat pipe is a refrigeration end, and when the heat pipes are placed in the freshness keeping box, the refrigeration ends can play a role in lowering temperatures due to the unique refrigeration effect of the pipes. The novel food freshness keeping box saves electricity and is environmentally friendly when compared with a traditional refrigeration and freshness keeping mode.

Description

A kind of novel foodstuff antistaling box

Technical field

The utility model relates to a kind of novel foodstuff antistaling box, belongs to food fresh-keeping field.

Background technology

At present, existing food fresh-keeping device is to utilize compressor compresses refrigeration mostly, thereby need to expend a large amount of electric energy.Meanwhile, utilize compressor cooling, can discharge waste heat, aggravated greenhouse effects.In order to make food fresh-keeping, and do not need to consume electric energy, develop this kind of device and have great importance for alleviation greenhouse effects, the saving energy.

Hot pipe technique is the heat transfer element of a kind of being called " heat pipe " of George Ge Luofo (George Grover) invention of U.S. Los Alamos (Los Alamos) National Laboratory in 1963, it takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, see through heat pipe the heat of thermal objects is delivered to rapidly outside thermal source, its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.

General heat pipe is comprised of shell, liquid-sucking core and end cap.Inside heat pipe is to be pumped into negative pressure state, is filled with suitable liquid, and this boiling point of liquid is low, easily volatilization.Tube wall has liquid-sucking core, and it consists of capillary porous material.Heat pipe one end is evaporation ends, one end is condensation end in addition, when heat pipe one end is heated, liquid in capillary evaporates rapidly, and steam flows to other one end under small pressure differential, and releases heat, regelation becomes liquid, liquid flows back to evaporation ends along porous material by the effect of capillary force again, and so circulation is more than, and heat reaches other one end by heat pipe one end.This circulation is carried out fast, and heat can be come by conduction continuously.

The main parts size of heat pipe is shell, end cap (end socket), liquid-sucking core, back (connection sealing element) four parts.At present existing heat pipe production technology, the heat pipe of producing can be directly used in daily life, is very easy to people's life.

Utility model content

Based on above-mentioned situation, the utility model is to provide a kind of device of simple environmental protection that the temperature in antistaling box is reduced, thereby reaches the object of food fresh keeping, and heat pipe is arranged in antistaling box, without utilizing electric energy, can't cause the pollution to environment.

To achieve these goals, the technical solution of the utility model is as follows.An antistaling box, comprises outer case, insulating, heat insulation vacuum layer, heat pipe and internal box, and wherein, internal box is placed in the middle of outer case, is disposed with insulating, heat insulation vacuum layer, heat pipe between outer case and internal box.

Preferably, heat pipe is many and is placed in internal box surrounding, and every heat pipe passes from internal box top, and the airtight internal box outside that is firmly attached to.

Preferably, every heat pipe is placed perpendicular to internal box bottom.

Preferably, insulating adopts insulation material.

Advantage of the present utility model is, has introduced hot pipe technique, and heat pipe one end is evaporation ends, the other end is refrigeration end, utilizes the refrigeration of heat pipe uniqueness, is placed in antistaling box, refrigeration end can play cooling effect, compares not only power saving but also environmental protection with traditional refrigerating fresh-keeping mode.

The beneficial effects of the utility model are: efficiently solve the problem that conventional antistaling box need to utilize machinery equipment refrigeration, saved the energy, also solved the larger problem of equipment occupation space, and can recycle.

In figure, 1, outer case, 2, insulating, 3, heat insulation vacuum layer, 4, heat pipe, 5, internal box.

The specific embodiment

In order to further describe the utility model, below in conjunction with accompanying drawing, further set forth the specific embodiment of this utility model.

Novel foodstuff antistaling box as shown in Figure 1, comprise outer case 1, insulating 2, heat insulation vacuum layer 3, heat pipe 4 and internal box 5, wherein, internal box 5 is placed in the middle of outer case 1, is disposed with insulating 2, heat insulation vacuum layer 3, heat pipe 4 between outer case 1 and internal box 5.

Wherein, heat pipe 4 quantity are many and are placed in internal box 5 surroundings, and every heat pipe 4 passes from internal box 5 tops, and airtight internal box 5 outsides that are firmly attached to.Every heat pipe 4 is placed perpendicular to internal box 5 bottoms.

Wherein, insulating 2 adopts insulation material.

The utility model in use, only need to be put into internal box 5 by the fresh-keeping food of needs, utilizes hot pipe technique to freeze.

The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
