Cold insulation member

Abstract

The present invention is aimed at providing a cold insulation member capable of cooling a cold insulation target to a predetermined temperature zone. A cold insulation member 10 includes a rapid-cooling layer 1, which includes a rapid-cooling heat-storage material 1 a for rapidly cooling the cold insulation target to the predetermined temperature zone in a predetermined time and a rapid-cooling heat-storage material accommodation portion 1 b for accommodating the rapid-cooling heat-storage material 1 a, and a temperature maintenance layer 2 which includes a temperature maintenance heat-storage material 2 a for maintaining the cold insulation target in the predetermined temperature zone for the predetermined time or longer and a temperature maintenance heat-storage material accommodation portion 2 b for accommodating the temperature maintenance heat-storage material 2 a and which is arranged beyond the rapid-cooling layer 1.

1 . A cold insulation member comprising:

         2 . The cold insulation member according to  claim 1 ,
 wherein the temperature maintenance heat-storage material has a phase change temperature higher than the phase change temperature of the rapid-cooling heat-storage material.   
     
     
         3 . The cold insulation member according to  claim 1 ,
 wherein the rapid-cooling heat-storage material has a phase change temperature lower than the predetermined temperature zone.   
     
     
         4 . The cold insulation member according to  claim 1 ,
 wherein the temperature maintenance heat-storage material has a phase change temperature lower than the predetermined temperature zone.   
     
     
         5 . The cold insulation member according to  claim 1 ,
 wherein part of the rapid-cooling heat-storage material is in a solid phase state and another part is in a liquid phase state in the temperature zone in which the cold insulation target is rapidly cooled.   
     
     
         6 . The cold insulation member according to  claim 1 ,
 wherein part of the temperature maintenance heat-storage material is in a solid phase state and another part is in a liquid phase state in the temperature zone maintained at a predetermined temperature of the cold insulation target.   
     
     
         7 . The cold insulation member according to  claim 1 , comprising:
 a heat-insulating layer which is arranged beyond the temperature maintenance layer and which includes a heat-insulating material.   
     
     
         8 . The cold insulation member according to  claim 1 ,
 wherein a total value of the amount of latent heat and the amount of sensible heat of the rapid-cooling heat-storage material is larger than the amount of cooling required for cooling the cold insulation target to the predetermined temperature zone, and   the temperature maintenance heat-storage material has an amount of latent heat required for maintaining the cold insulation target in the predetermined temperature zone for the predetermined time or longer.   
     
     
         9 . The cold insulation member according to  claim 1 ,
 wherein the rapid-cooling layer has flexibility at the phase change temperature of the rapid-cooling heat-storage material.   
     
     
         10 . The cold insulation member according to  claim 1 , comprising:
 a plurality of rapid-cooling layers,   wherein the plurality of rapid-cooling layers are connected to each other.
