Design and simulation of heat dissipation exhaust of GM Isotta floating engine for generating electrical power in flexible thermal actuators

In this paper, a new method was presented for recovering dissipated heat in the exhaust of GM Isota floating engine and converting it to electricity using a flexible thermal anchor. The flexure uses three parallel arms including the hot and cold arms to control temperature and generate electrical power. Also, three dimples were used in the shortest arm for thermal stability in order to control the core temperatures. In other words, the purpose of the present paper was developing a passive heat transfer method and a heat generating system was employed for recovering dissipated heat to generate electrical power. Size of proposed design was equal to 40µm × 250µm, and it was implemented and simulated in COMSOL software 2018. Simulation results for proposed design with the voltage of 5V and maximum temperature of 550K presented acceptable FOM compared to similar work such that it showed the value of 2.3 times relative to the best design ,and it was 2700 times better compared to the worst design.
