Can colouring agent be dripped in described phase-change material 3, hyperchromic to phase-change material, with prevent because of certain can not antigen because of the phenomenon eaten by mistake of consumer when the heat-insulation layer that causes absorbing heat is revealed.
Described colouring agent is natural colorant or Prof. Du Yucang colouring agent.
Described natural colorant is the one in capsanthin, beet red, Monascus color, alkermes, chrysanthemum, chlorophyll copper sodium, turmeric, Gardenia Yellow, carrotene, algocyan, cacao color or caramel colorant.
One in described Prof. Du Yucang colouring agent famille rose, amaranth, sunset yellow, erythrosine, lemon yellow, newly red, indigo or light blue.
The volume fraction of the colouring agent of described dropping is 0.001% ~ 20%.
Described inwall 1 material is the one in aluminium, copper, stainless steel, pottery or glass.
Described outer wall 5 material is the one in polyethylene, polypropylene, Merlon or polymethyl methacrylate.
The monolithic fin of described thermofin group is the one in rectangular structure, wavy shaped configuration or helical structure.
During use, pour in container by high-temp liquid 5, the thermofin absorbed heat in container in heat-insulation layer 2 groups transfers heat to rapidly phase-change material 3, and phase-change material 3 is endothermic melting, the cooling-down effect of the liquid 5 that reaches a high temperature.When cooling to the freezing point of phase-change material 3, phase-change material 3 solidifies heat release, realizes heat insulation function, and namely container can make liquid 5 temperature temperature remain near the transformation temperature of phase-change material for a long time.
One heat absorption cool-bag tool described in the utility model has the following advantages:
(1) thermofin in this container can adopt close-fitting or welding procedure to fix with container inner wall, and various structures, the contact area of heat transfer is very large, reduces thermal contact resistance, improves heat exchange efficiency further.
(2) structure of this container has taken into full account the impact that the expansion of phase-change material may bring, and thermofin thermal conductivity is higher, and the latent heat of phase change of phase-change material is comparatively large, and both are combined, and substantially increase cooling and the heat-insulating property of container.
(3) this container use phase-change material and thermofin be extensively easy to get, with low cost, applicable crowd is more extensive.
(4) this container can be used for the articles for daily use such as water tumbler cup, body of vacuum cup, vacuum cup cover (cup is incubated, and bowl cover is lowered the temperature), foot washing basin, baby bottles, and the scope of application is more extensive.
