| Abstract | The air-cooled motor controller has been widely used in electric aircraft due to its simple heat dissipation structure and maintenance-free features. Being the main heating component of the electric propulsion system of electric aircraft, the weight and the volume of the air-cooled motor controller need to be strictly controlled. Due to the short power running time of the electric motor controller, there is a large weight and volume allowance margin for the air-cooled radiator-based on the rated power and heat dissipation requirements of the motor controller.This paper proposes an air-cooled radiator design method that can reduce its volume and weight by optimizing its structure based on the operating conditions of the electric aircraft under the heat dissipation requirements.The structure of the air-cooled motor can be optimized by optimizing the structure the minimum structure of the motor controller radiator constrained by the maximum temperature of the Insulated Gate Bipolar Transistor (IGBT) module,which can be determined using an algorithm called the motor controller thermal resistance network model. Experimental results obtained from a prototype test on a two-seat electric aircraft demonstrate the effectiveness of the optimization method. The air-cooled radiator designed using the proposed method can be reduced by 5% in weight while meeting the heat dissipation requirements of the motor controller of the electric aircraft. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
