Studying a local thermoelectric cooling device for automobiles

This article discusses how the TEMs are working to create a cool air environment and cool the car's cooling process. Particular attention is paid to the structure and operation of TEMs. The cold side temperature TEM is based on a special air cooler, which is fixed to the cooling air. The flow of air passing through the cooling radiators from the series was generated by a separate propeller. All in all, the analysis of the results shows that the thermoelectric cooling devices based on the Pelte module can be used for cooling the environment and move the cooled air to the interior of a car to improve microclimate in local conditions. A fan sits adjacent to the core to blow the cold outside air over it. As the cold air travels over the core, it heats up, and then it enters the cabin through heater vents. The air conditioning system relies on Freon, a compressed gas, to keep cool. The fan speed that generates the fan is controlled by the voltage value. The voltage to the fan was changed to 8–12 V, and the results were obtained. Temperatures of the cooled air, hot TEM radiators and cooling fan radiators were measured.
