FIG. 2 is an enlarged view of a structure of a motor boom, Fig. 3 is an exploded perspective view showing the heat dissipating unit of Fig. 1 as disassembled from the motor boom. Fig.

As shown in these drawings, a motor boom having a heat dissipating unit according to an embodiment of the present invention is provided with a motor 2 and a propeller 3 at an end portion extending from the main body 1 of the multi- A motor boom 100 of a multi-copter for moving the main body 1 of the multi-copter to a desired position in a floating state; An electronic transmission 200 provided to control the motor 2 and a heat dissipation unit 300 disposed in contact with the electronic transmission 200 and discharging heat generated in the electronic transmission 200 to the outside, .

The motor boom 100 is disposed symmetrically on the outer surface of the multi-coperator body 1 and includes a propeller 3 capable of lifting a multi-copter at an end thereof and a motor 2 for rotating the propeller 3 Is a member to be installed.

The motor boom 100, which is extended from a side of the multi-copier main body 1 to a predetermined length, is detachably provided in the main body 1 of the multi-copter, which is preferable from the viewpoint of carrying and carrying the multi-copter.

When the motor boom 100 is attached to the main body 1 of the multi-copter, the vertical length of the longitudinal section of the motor boom 100 is formed to be longer than the longitudinal width of the vertical section so that the motor boom 100 can cope with bending, twisting and shearing stress .

Here, in the case of the torsion and shearing stress, the vertical width of the motor boom is increased as compared with the conventional case, and the total cross-sectional area is increased, so that the torsion and shearing stress are increased.

In the case of bending, the load is applied to the motor boom due to components such as a motor and a propeller installed at the end of the motor boom 100. [

This bending stress is proportional to the acting bending moment and the distance from the neutral axis of the longitudinal section so that the vertical width of the longitudinal section of the motor boom 100 is formed to be longer than the lateral width and the vertical width is increased so that the bending moment and the longitudinal moment from the neutral axis As the distance increases, the size increases.

A receiving groove 110 capable of receiving the electronic transmission 200 is formed at a predetermined depth on one side of the outer surface of the motor boom 100 and the electronic transmission 200 is accommodated in the receiving groove 110.

The size of the receiving groove 110 is formed to have the same width and length as the size of the circuit board of the electronic transmission 200 so that when the electronic transmission 200 is inserted into the receiving groove 110, To be in close contact with the side surface of the circuit board 210 to prevent the electronic transmission 200 from flowing.
