Title:
ELECTRONIC SPEED CONTROLLER ASSEMBLY, POWER SYSTEM, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/041241
Kind Code:
A1
Abstract:
An electronic speed controller assembly comprises a first electronic speed controller (101) for driving a first motor (202), a second electronic speed controller (102) for driving a second motor (203), and a radiator assembly (103) provided between the first electronic speed controller (101) and the second electronic speed controller (102). The first motor (202) and the second motor (203) are used to respectively drive an upper propeller (2011) and a lower propeller (2012) to generate lifting forces. The first electronic speed controller (101) and the second electronic speed controller (102) are arranged in an inverted manner. The radiator assembly (103) comprises a radiator main body (1031), a heat-conducting metallic member (1032), and a heat dissipation pipe (1033). The heat-conducting metallic member (1032) and the heat dissipation pipe (1033) are mutually connected and provided at the radiator main body (1031). The first electronic speed controller (101) and the second electronic speed controller (102) are respectively in contact with the heat-conducting metallic member (1032) to transfer generated heat to the heat-conducting metallic member (1032), thereby solving problems in which prior art electronic speed controllers havepoor heat dissipation performance, low maintainability and excessively large sizes. Also disclosed are a power system and an unmanned aerial vehicle.
