Abstract

The invention relates to a passive constant temperature system applied to a thermal-insulating container. The passive constant temperature system comprises an outer shell, an inner wall and a cover, and is characterized in that a heat pipe and a phase-change material layer are arranged between the outer shell and the inner wall in turn; a vacuum chamber is also arranged between the outer shell and the inner wall; a handle is arranged on the outer shell; and a separating plate is arranged in the interior of the shell. Compared with a traditional thermal-insulating container, the passive constant temperature system applied to the thermal-insulating container according to the technical scheme has the advantages that a thermal-insulating function, energy conservation and environmental protection are realized without the usage of an external heat source because a phase-change material and the heat pipe are used together; articles in the container are subjected to uniform thermal-insulation due to the combined usage of the phase-change material and the heat pipe; selected materials are simple and common and are low in manufacturing cost; a thermal-insulating effect is excellent; a thermal-insulating time is long; the manufacturing is convenient and the use is simple; and the defects of the thermal-insulating container of the prior art that heat is quickly lost, the thermal-insulating effect is undesirable and the thermal-insulating effect is often realized by switching in the external heat source are overcome.

Description

A kind of passive constant temperature system that is applied to cool-bag
Technical field the present invention relates to a kind of insulation utensil.
Cool-bag kind and quantity that the background technology existing market is sold are many, but in default of effective technical means, it is very fast to make that heat scatters and disappears, and heat insulation effect is undesirable.Under many situation, be to realize heat insulation effect through inserting extraneous thermal source.
The technical matters that summary of the invention the present invention will solve is, increases substantially the heat insulation effect of cool-bag through a kind of technological means, need not the external energy.For solving the problems of the technologies described above, the present invention proposes following technical scheme: a kind of passive constant temperature system that is applied to cool-bag, comprise shell, and inwall, lid, its feature is: between shell and inwall, be sequentially with heat pipe and phase-change material layers.Between shell and inwall, also can be provided with vacuum chamber.Phase-change material layers is organic phase change material or inorganic phase-changing material, composite phase-change material.The tube wall material of heat pipe is metal or non-metal.Be designed to centreless in the heat pipe pipe or core is arranged.The heat pipe intraductal working medium is water or cmpd.The heat pipe cross section is circular or square.Shell is provided with handle.Inside is provided with dividing plate.
Adopted the passive constant temperature system that is applied to cool-bag of above technical scheme, compared, had following advantage:, do not used extraneous thermal source just can realize heat insulation function, energy-conserving and environment-protective because phase-change material and heat pipe are united use with traditional cool-bag.Phase-change material and heat pipe are united use, can also realize the even insulation of article in the container.The material of being selected for use is simply common, and is cheap.High insulating effect, temperature retention time is long.Easy to make, use simple.
Description of drawings Fig. 1 is a structural representation of the present invention
The specific embodiment explains further details to the present invention below in conjunction with accompanying drawing.As can be seen from Figure 1, the same shell 1 that is provided with of the present invention, inwall 5, lid 7 with common insulation utensil.The present invention is with generally normal
The different part of insulation utensil of seeing is: between shell 1 and inwall 5, be sequentially with heat pipe 3 and phase-change material layers 4.Heat pipe 3 is close to placement with phase-change material layers 4.
Shell 1 of the present invention can also be made interlayer, forms inner chamber 2, vacuumizes, and many again settings are incubated measure between inwall 5 like this.The equal available metal of material, corrosion-resistant steel or the plastic production of shell 1 and inwall 5, shape can be the open circles cylindricality, opening multi-edge column-shaped etc.Phase-change material 4 can be selected according to the temperature of the required maintenance that is incubated object, comprises organic phase change material, inorganic phase-changing material and composite phase-change material;
Heat pipe 3 can adopt any one in general heat pipe, separate heat pipe, capillary pump loop heat pipe, micro heat pipe, pulsating heat pipe, flat-plate heat pipe, the radial heat pipe.The internal structure of heat pipe 3: the form that can adopt centreless.The individual layer and the multilayer web-roll core of tube wall is close in employing.Adopt the sintered powder tube core, axial slot formula tube core, combined die etc.
The material of heat pipe 3: can adopt copper, aluminium, carbon steel, corrosion-resistant steel, alloy steel and other metals, also can adopt non-metallic materials such as pottery, glass or plastics.The working medium of heat pipe 3: can be water, also can be cmpds such as alcohol, acetone, methyl alcohol, fluorhydrocarbon.The cross-sectional plane of heat pipe 3 can be a standard circular, also can be oval, and square, rectangle, pancake, corrugated etc.The installation form of heat pipe 3: can be single tube and also can be multitube, is the radial of center with cool-bag bottom, with inwall 5 be the external world around shape etc.For being convenient for carrying generally mounting knob 6 on shell 1.On inwall 5, establish step to place shelf 8, so that food or article are shelved in layering.
During use, earlier temperature in the container is reached the phase transition temperature of phase-change material, can realize through pouring the hot water that is higher than phase transition temperature into.The article that will be incubated again (like food) are directly put into container, can realize insulation, no longer need add extraneous thermal source.High insulating effect, temperature retention time is long, uses simple and convenient.
