CN2063115U - Multi-layer composite container of thermal insulation - Google Patents

Abstract

The utility model discloses a multi-layer composite container of thermal insulation, comprising an inner wall, an outer shell and a heating element. The utility model is characterized in that multilayer of the composite thermal insulation layers are additionally arranged between the inner wall and the outer shell, and the inner wall can be made from the aluminium thin sheet. The utility model has the advantages of portable, anti-pulling, anti-pressure and anti-collision, the thermal insulation property is good, and the material is saved. The utility model can be manufactured to the containers of thermal insulation with various shapes and different specifications, such as the wall hanging type, because the shape and the specification of the inner wall and the outer shell are not restricted; the utility model is suitable for the thermal insulation, and can be used as an electric water heater, a rice steaming cabinet and a vehicle for transporting the food with thermal insulation for a family, an enterprise and unit, a hotel, a restaurant and a hospital.

Description

Multi-layer composite container of thermal insulation

The utility model relates to a kind of container that is used to be incubated.

Existing cool-bag is many to be made of inner bag and shell, inner bag adopts bilayer and centre to be evacuated and realizes insulation, or between inner bag and shell, set up a heat-insulation layer, these cool-bags not only heat insulation effect are not good enough, and take material, perishable, if its volume of increase then weight will greatly increase, be not easy to carry, carry or make other shape.

The purpose of this utility model is to provide a kind of light, multilayer composite heat insulating container of economizing material, durable, high insulating effect.

The utility model is realized by following scheme, described cool-bag is made of inwall (1), shell (4) and heater element (5), one insulating composite layer (2) (3) is set between inwall and shell, and this composite bed is composited by inorganic heat insulation material (2) and organic foam plastic.Thin and the ceramic of the available aluminium of inwall (1) gets, and the aluminium of the most handy 0.05～0.5mm is thin; Shell (4) can adopt wood materials, plastics or iron sheet to make, and can be made into difformity, not shell in specie; Inorganic heat insulation material (2) can be super glass wool (felt) or litaflex, or rock wool heat-preservation felt etc. is by smearing, paste or simple and easy tying up wraps up inwall is smooth, process sprays such as the available polyvinyl chloride of organic foam plastic (3) or polyurethane or expandability GPPS or mold pressing make it to combine closely with above-mentioned warm material (2), in order to reduce glass felt (cotton), litaflex, the hygroscopic character of inorganic material such as rock wool heat-preservation felt, increase the mechanical strength and the solid shape property of composite bed, tackle this composite bed and push, make it to reach optimum capacity.This cool-bag also is provided with cooling water inlet (6) and hot water outlet (7).

Below in conjunction with accompanying drawing the utility model is further described, content of the present utility model is not limited thereto.

Fig. 1 is the section-drawing of the embodiment of the utility model; (1) is the thin inwall of aluminium of 0.1mm among the figure, and (2) are superfine glass felt heat-insulation layer, and (3) are the damp proof heat-insulation layer of polyurethane foam plastic, and (4) are iron sheet outer casing, and (5) are heat element, and (6) are cooling water inlet, and (7) are hot water outlet.

Because inwall of the present utility model is to adopt thermal conductivity factor little (0.065 kilocalorie/meter time ℃) aluminium that wall is thin to make, as electric heater with or other cool-bag can save 46～85% aluminium when using; In addition the heat-insulation layer of this container is owing to select thermal conductivity factor little (0.027～0.047 kilocalorie/meter time ℃), good (1.5～2 kilograms/cm of compression strength of mechanical strength²) inorganic heat insulation material and organic foam plastic combine closely and be squeezed into composite bed, therefore make this two classes material pluses and minuses separately obtain abundant complementation, thereby it is light that this cool-bag is had, anti-drawing, withstand voltage, anti-collision, the characteristics such as heat-insulating property is good, moreover the inwall of this cool-bag and shell shape are unrestricted, can be made into various shapes, the container of specification, as wall-hanging etc., so be applicable to home-use warmer, the institutional settings electric heater, the canteen, the hotel, the restaurant, hospital's steam-cooking cabinet, vehicle for transporting foods with ability of keepings etc. are a kind of light, attractive in appearance, durable Novel heat insulating container.

Claims (5)

1, a kind of multilayer composite heat insulating container is made of heater element (5), inwall (1) and shell (4), and it is characterized in that: the composite heat-insulating layer of setting up between inwall and the shell is composited by inorganic heat insulation material (2) and organic foam plastic (3).

2, cool-bag according to claim 1 is characterized in that described inorganic heat insulation material (2) can be super glass wool (felt), litaflex goods, rock wool heat-preservation felt, cement pearl rock product.

3, cool-bag according to claim 1 is characterized in that: described organic foam plastic (3) can be polyurethane, polyvinyl chloride, the expandability GPPS.

4, cool-bag according to claim 1 is characterized in that: the available aluminium of inwall (1) approaches or stupalith is made.

5, cool-bag according to claim 1 is characterized in that: available wood materials of shell (4) or plastics or sheet tin are made.
