Abstract
The utility model relates to a thermal insulation box which comprises a box cover (1) and a box body (2). The box cover (1) and the box body (2) are both of three-layer structures. The box cover (1) comprises an upper cover (11) and a lower cover (12), and a box cover thermal insulation layer (13) is arranged between the upper cover (11) and the lower cover (12). The box body (2) comprises a box body outer layer (21) and a box body inner layer (22), a box body thermal insulation layer (23) is arranged between the box body outer layer (21) and the box body inner layer (22), the box cover thermal insulation layer (13) is formed by a first foamed plastic layer (14) and a first vacuum thermal insulation plate (15), and the box body thermal insulation layer (23) is formed by a second foamed plastic layer (24) and a second vacuum thermal insulation plate (25). The vacuum thermal insulation plates are used as thermal insulation materials, and thermal insulation effect is achieved well without increasing of thickness of the thermal insulation layers.
Description
Technical field
The utility model relates to a kind of insulation can, particularly a kind of high-efficiency insulated case that uses vacuum heat-insulating plate.
Background technology
In daily life, the warm material that common insulation can is commonly used comprises Polyurethane foam, phenolic resin foam plastics and polystyrene foam etc., and thermal conductivity value is relatively high, wants to obtain good heat insulation effect, needs larger insulation layer thickness.But consider the practicality of insulation can, the normal conditions heat-insulation layer is thick in 5-6 centimetre at the most, and therefore causing on the market, existing insulation can not reach best heat insulation effect.
Vacuum heat-insulating plate is comparatively advanced in the market warm material.For the warm material of same thickness, vacuum heat-insulating plate has the impayable heat insulation effect of other material, the minimum 0.003w/m.k that reaches of thermal conductivity, its thermal conduction rating be only same thickness the polystyrene thermal insulating material 1/10.But there is defective equally in vacuum heat-insulating plate, and namely its profile is comparatively single and can not cut.
The utility model content
The technical problems to be solved in the utility model is to provide the insulation can that a kind of heat-insulation layer is thinner, heat-insulating property is outstanding.
A kind of insulation can comprises case lid and casing, and described case lid and casing are three-decker, and case lid comprises upper cover and lower cover, is the case lid heat-insulation layer between upper cover and lower cover; Casing comprises casing skin and casing internal layer, be the cabinet insulation layer between casing skin and casing internal layer, it is characterized in that described case lid heat-insulation layer is made of the first foam layer and the first vacuum heat-insulating plate, the cabinet insulation layer is made of the second foam layer and the second vacuum heat-insulating plate.
Preferably, described the first vacuum heat-insulating plate is close to upper cover, is the first foam layer between the first vacuum heat-insulating plate and lower cover; The second vacuum heat-insulating plate is close to the casing skin, is the second foam layer between the second vacuum heat-insulating plate and casing internal layer.Preferred, the first vacuum heat-insulating plate is fixed in upper cover by stickup, and the second vacuum heat-insulating plate is fixed in the casing skin by stickup.
Preferably, described casing internal layer is reserved with fills mouthful, and is furnished with the upper cover of can open and close filling mouthful; The foamed plastic that casing internal layer and vacuum heat-insulating plate interlayer are filled, form that can particle mouthful is filled into heat-insulation layer by filling, and foam grain is filled than direct placement foam plastics slab, can avoid the generation in space, reaches better heat insulation effect.
Preferably, the foamed plastic in heat-insulation layer comprises Polyurethane foam, phenolic resin foam plastics or polystyrene foam.
The beneficial effects of the utility model are: under the prerequisite that does not increase insulation layer thickness, realized better heat insulation effect.
Description of drawings
Fig. 1 is the cutaway view of the utility model insulation can the first embodiment.
In figure: 1. case lid; 11. case lid is outer; 12. case lid internal layer; 13. case lid heat-insulation layer; 14. case lid vacuum heat-insulating plate; 15. case lid foam layer; 2. casing; 21 casings are outer; 22 casing internal layers; 23 cabinet insulation layers; 24 casing vacuum heat-insulating plates; 25 casing foam layers; 26 fill mouth; 27 upper covers

Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1
As shown in Figure 1, a kind of insulation can comprises case lid 1 and casing 2, described case lid 1 and casing 2 are three-decker, case lid 1 comprises upper cover 11 and lower cover 12, is case lid heat-insulation layer 13 between upper cover 11 and lower cover 12, and the case lid heat-insulation layer is made of Polyurethane foam plate and vacuum heat-insulating plate; Casing 2 comprises casing outer 21 and casing internal layer 22, be cabinet insulation layer 23 between casing outer 21 and casing internal layer 22, cabinet insulation layer 23 consists of by Polyurethane foam chip and vacuum heat-insulating plate, vacuum heat-insulating plate is close to casing outer 21 and is placed, polyurethane-foam particles is packed between vacuum heat-insulating plate and casing internal layer 22 by filling mouth 26, fill complete rear covering with lid 27 and fill mouth 26, lid 27 is screwed on casing internal layer 22.In the present embodiment, the thermal-insulating body gross thickness is 5cm, and wherein the casing foam layer is 3cm.
Embodiment 2
The casing foam layer 25 of embodiment 2 is made of polystyrol plastic foam plate, no longer needs the filling foamed plastics particle, so fill mouth 26 and lid 27, all the other are with embodiment 1.
Principal character of the present utility model and inventive point have only been described in above demonstration.Those skilled in the art should understand, and the utility model is not restricted to the described embodiments.Under the prerequisite that does not break away from inventive point and protection domain, the utility model also has various variations, and these changes and improvements all will fall in the claimed scope of the utility model.
