Abstract: This application provides a photographing device. The photographing device includes a housing, configured to carry an electronic component of the photographing device, such as a lens module and an expansion module. A lens cavity and an expansion cavity isolated from each other are disposed in the housing. The lens module is disposed in the lens cavity, a heat dissipation apparatus is disposed in the expansion cavity, and the expansion module is disposed on the heat dissipation apparatus and is thermally connected to the heat dissipation apparatus. In addition, the disposed heat dissipation apparatus is further thermally connected to the lens module. A heat dissipation channel isolated from the expansion cavity is disposed in the heat dissipation apparatus. Therefore, an effect of dissipating heat from the expansion module and the lens module may be improved through air flowing in the heat dissipation channel.
