|1. (WO2018201812) DUCTED FAN|
|Applicants:||SHEN ZHEN KUANG-CHI HEZHONG TECHNOLOGY LTD.
A ducted fan (100) comprises: a duct (10), having a central axis; a duct support (20), disposed inside of the duct, and a central axis thereof being coincident to that of the duct; a fan (30), disposed adjacent to an air intake of the duct, and being rotatable about the central axis of the duct support; a heat sink (23), embedded in the duct support, and part of air flow in the duct being flowing therethrough; and a power driving device; connected to the fan to drive the fan to rotate, wherein the power driving device is connected to the heat sink to form a loop for liquid coolants and the heat is dissipated by means of the heat sink. By embedding a heat sink in a duct support and using a fan to create high-speed air flow in the duct, the present invention enables high efficiency of heat dissipation performance of the heat sink and increases the cooling efficiency of an aircraft engine using a liquid-cooled engine as a power system, thereby decreasing the size of a heat sink and the weight of the aircraft, and also saving space for the aircraft.
