Embodiment 2
[0059] The difference between this embodiment and embodiment 1 is that the EPP material is replaced by EPS (polystyrene foam) material. Correspondingly, in step 6 of the production process, the temperature of the steam used for foaming the EPS particles is 90-110° C., and the steam pressure is 0.1 MPa-0.4 MPa. All the other parts are the same as in Embodiment 1, and the structure of the cold chain incubator is also the same as in Embodiment 1, so no further details are given.
[0060] further reference image 3 , the EPS and VIP integrally molded cold-chain incubator provided in this example has a size of 420mm*350mm*240mm, and the thickness of VIP is 10mm. The cold-chain incubator is placed in 6.15kg of cooling agent at an ambient temperature of 37°C. The change of the temperature in the center of the box is as follows: image 3 As shown, the time for maintaining the temperature in the center of the box below 8°C is 87.2 hours, and the time for maintaining the temperature i...
