In this paper, We describe the way to manufacture Cooler Pack using peltier element. The goal of this is to replenish Vaccines in a good condition for children who living in low vaccine coverage areas. 12V DC 18AH battery supply a power and peltier element makes cool a box until the set temperature by digital temperature controller. But when peltier element operate, heat of the element increase and the heat makes the element breakdown. So we place a fan in order to cool a heated surface of peltier element. We expect to be applied for motor cooling, cooling of electronic components, and mountaineering bags.
