Heat dissipation device for mechanical joint motor and mechanical exoskeleton device

The utility model provides a heat dissipation device for a mechanical joint motor and a mechanical exoskeleton device. Comprising an air guide cylinder sleeving a cooling fin of the mechanical joint motor; a first channel is formed in the air guide cylinder, an annular cylinder is arranged in the first channel, the annular cylinder is provided with a second channel with the aperture smaller than that of the first channel, and the first channel, the second channel and a channel area between the first channel and the second channel allow air blown out of the cooling fins to pass through; an air blowing assembly is arranged in the second channel and is configured to rotate under the driving of air blown out by the cooling fins and blow air to the air outlet of the air guide cylinder; the size of an air blowing area of the air blowing assembly is matched with the size of the hole diameter of the second channel. The utility model aims to solve the problem that the joint motor is overheated and even damaged due to
