Fig. 3 is the temperature versus time curve figure in cold chain heat insulation box in the preferred embodiment of the present invention 2；
Embodiment
This case is described in further detail with reference to the accompanying drawings and detailed description.
With reference to Fig. 1, a kind of cold chain heat insulation box, including：Cover plate 1 and casing 2；The cover plate 1 is foamed by VIP cover plates and EPP
Layer 3 is integrally composited, and the casing 2 is integrally composited by VIP casings and in the EPP foaming layers 3 of VIP box outer surfaces.
In the present embodiment, with one piece of VIP as the VIP cover plates, the VIP casings are bonded by five pieces of VIP4 and formed
Top end face is the cuboid of opening surface；Wherein 4 pieces VIP4 are bonded as the side of cuboid, one piece of VIP4 as cuboid bottom surface
Bonded with the bottom face of the side.
In order to further increase protection of the EPP foaming layers 3 to VIP4, the top end face of the VIP casings circumferentially has
One circle and the integrally formed EPP foaming rings of the EPP foaming layers 3.By the foaming ring, four pieces are located at the VIP4 of side top
End face carries out covering protection with EPP foaming rings.Likewise, the side of the VIP cover plates circumferentially has a circle EPP foaming
Circle, is protected by the foaming ring to a circle side of VIP cover plates.
In the present embodiment, an inner bag 5, the outer surface of inner bag 5 and the inner surface top of VIP casings are also set up in the casing 2
