The objective of this study is enhanced thermal performance of the high voltage PTC heater for using a heat source of the electric vehicle or fuel-cell electric vehicle. To optimize performance, design for six sigma(DFSS) Technique was used in this paper. Optimization is made by changing the shape and size of the heater fin. In conclusion, the new high voltage PTC heater is technically superior to its previous PTC heater. Thermal performance and pressure drop is approximately 17% improved.
