title: [Design and manufacture of medical shipping refrigerated box].
abstract: OBJECTIVE
  To develop a set of low temperature medical shipping refrigerated box for storage and shipping for biologicals in field environment.
  
  
  METHODS
  Semiconductor cooling device (SCD) and phase change energy storage materials (PCESM) were adopted as the means for refrigeration and coolness storage, coolness was produced by SCD and stored by PCESM while power source present, and low temperature state for biologicals was keep by PCESM.
  
  
  RESULTS
  The problem for biologicals storage and shipping in low temperature state for medical experiment and clinic was resolved.
  
  
  CONCLUSIONS
  Medical shipping refrigerated box can be used not only in medical, but also in other field such as food storage and shipping, etc.
