Summary:

This technical report studies the development of a thermoelectric cooler based steering cooling system. Automotive vehicles are subjected to varied climatic conditions based on location and season. The Indian sub-continent withstands severe heat during summer, a vehicle parked in sun on a summer afternoon experiences greenhouse heating and its internals heat up. The part of heated car cabin which creates discomfort include seat, steering, gear knob and other touch points. Thermoelectrics have found wider acceptance amongst automotive industry and many articles have been published investigating implementation of thermoelectrics in automotive system. The paper deals with different 3D concepts', transient formulation of a 1D mathematical model in' and a prototype tested with the predefined boundary conditions of the 1D model in transient'. Thermoelectric cooler' performance maps obtained from the supplier and were used for creating a COP based thermal model to induce the Peltier effect. To have a constant temperature interface on the hot side of TEC, Phase Change Material was carefully selected for constant temperature heat sink. Initial 1D model was built from the data obtained through multi domain CFD simulation. Concept was iteratively refined in a 1D thermal model, and the prototype was tested for validation of the proposed 1D model. The model and testing was done in transient condition assuming an initial steady state temperature of 55°C to measure the fall in average surface temperature of the vehicle steering within the first 20 seconds of the driver's entry
