Automated car safety seat cooling system using thermoelectric cooler

An increasing number of deaths and injuries are reported in recent years for small children and physically challenged persons left in unattended parked vehicles when the surrounding air temperatures are warmer. Thermal abatement measures such as tinted windows and circulation fans have generally proved insufficient in reducing peak temperatures to a safe level. Due to prolonged time periods, the body temperature gets elevated so that injuries and deaths occurs for the children left alone in the vehicles . The solution for the problem is the design of a car safety seat using thermoelectric cooler that offers protection to the occupant temporarily. To maintain the temperature of the body for a limited time within acceptable range, thermoelectric cooling and forced air convection are featured by thermoelectric cooled seat. Thermoelectric cooling systems have been developed for the temperature control of sensitive electronic equipment, green applications and it is used to heat rejection. A seat occupant sensor and thermistor will detect an unsafe temperature rise for small child and activate the alarms and cooling systems. Thermoelectric coolers maintain the cabin air temperature up to 2hrs below the threshold in parked vehicles.
