“…Table 3 lists the potential materials with their respective thermal conductivity values. Among these materials, the heat pipe is an efficient type of heat transfer device that has been adopted in the design of electrical machines in some studies and inventions [26,27]. The thermal conductivity of heat pipes can reach 10 4 W/mK, far exceeding that of the common thermal conductive materials.…”

Equipped with a distributed electric propulsion system, eVTOL is the primary vehicle for future urban air mobility. The electrical machine determines the weight of the distributed electric propulsion system, and the cooling capability determines the electrical machine’s weight. The electrical machine with air cooling is preferred for eVTOL due to its simplicity and light weight. This paper presents a new air-cooling system for an electrical machine in an electric ducted fan propulsion system. The novel cooling system consists of a cooling guide vane with a heat pipe (CGVHP), which is located downstream of the ducted fan rotating blade. The heated end of the heat pipe is inserted into the stator end windings and the cold end is inserted into the cooling guide vane. The heat generated in the windings is transmitted to the cooling guide vane by the heat pipe and dissipated by the forced convection using low-temperature air passing through the ducted fan. The cooling performance of the cooling guide vane with the heat pipe was numerically simulated, considering several critical design factors. The simulation results showed that the proposed CGVHP can be helpful for reducing the winding temperature of the electrical machine by over 25.5 °C at the peak power condition of 15.7 kW.

“…One novel electric machine heat extraction idea patented is the use of heat pipes in [19]. [20] and [21] investigate using heat pipes in end windings and stator back iron respectively while [22] explores implementing heat pipes within the stator slot. At Marquette University, a unique motor plus TMS design has been proposed in [23] to achieve the demanding specifications in Fig.…”
