The present invention relates to a radiator for a transmission of an unmanned aerial vehicle (UAV), wherein a connection member to couple a motor to an arm of the UAV is formed in a sealed container type, the transmission is disposed in the connection member, and insulating oil is filled in the connection member to radiate heat of the transmission, such that a heat radiating plate integrally formed in the transmission is not required, such that the volume and weight of the transmission are reduced. To this end, the radiator for a transmission of an UAV comprises a plurality of arms protruding from a fuselage in four directions, a connection member having a transmission, which is an electric speed controller (ECS), embedded therein and installed in the front end of each arm, and a motor having a blade, and mounted on the upper, or the upper and lower surfaces of the connection member, such that revolutions per minute (RPM) are controlled through the transmission. Accordingly, a heat radiating plate is removed from the transmission and thus the volume of the transmission is reduced. The connection member is installed in a sealed state and is filled with the insulating oil to immerse the transmission therein, and thus heat of the transmission is radiated to the outside of the connection member through the insulating oil.

    본 발명은 비행기의 아암에 모터를 결합시키는 연결부재가 밀폐용기 형태로 구성되고, 상기 연결부재에 변속기를 넣고 절연유체를 채워서 상기 변속기의 방열이 이뤄지도록 함으로써, 상기 변속기에 일체형으로 구비되는 방열판이 불필요하므로 부피가 줄어들고 무게가 경감되는 무인비행기의 변속기 방열장치에 관한 것이다. 이를 위하여 본 발명은 기체에서 사방으로 돌출되는 다수의 아암이 구비되고, 각 아암의 선단에는 전자식 속도제어장치(ESC)인 변속기를 내장한 연결부재가 구비되고, 상기 연결부재의 윗면 또는 윗면과 아랫면에는 날개를 갖는 모터가 장착되어서 상기 변속기를 통하여 회전수가 제어되는 무인비행기의 변속기 방열장치에 있어서, 상기 변속기는 방열판이 제거되어 부피가 감소되고; 상기 연결부재는 밀폐상태로 구비되며; 상기 연결부재는 상기 변속기가 잠기는 절연유체가 충진되어서 상기 변속기의 열기가 절연유체를 통하여 상기 연결부재의 외부로 방열되도록 한 특징이 있다.
