The ventilation pipe 203 and the heat dissipation fin 204 are made of materials with good heat conductivity. When the hot air passes through the ventilation pipe 203, it exchanges heat with the outside through the multiple slender ventilation pipes 203, thereby accelerating the heat dissipation of the hot air. The heat dissipation fin 204 further increases the heat dissipation area of the ventilation pipe 203, thereby further accelerating the heat dissipation of the hot air, so that the hot air is better cooled. The cooled air is introduced into the optical cable terminal box shell 1, thereby better dissipating heat inside the optical cable terminal box shell 1.
