Vaccine cold boxes are used for storing as well as transporting vaccine at precisely controlled temperature range. The aim of this paper is to define a design methodology in selecting a thermoelectric module (TEM) for a portable vaccine cold box that maintainsan internal temperature between 2-7oC. A Cold box is designed based on the principle of thermoelectric effects (i.e. Peltier effect) wherethe cold side of the TEM is attached to the cold box for extracting the heat load and maintain the required temperature range inside it. The heat from the hot side is ejected to surrounding with the help of heat sinks and fans for the enhancement of thermoelectric performance. The study provides the methodology for the selection of available Peltier’s and usage of these Peltier’s in the design of cold box. Based on the study it is observed that the minimum temperature in the vaccine box can be reached to 5oC which indicates that the vaccine cold box can be maintained at desired temperature.
