A projection device includes a housing, a projection module, a fan, and at least one stopper wall structure. The housing has an air inlet, a first air outlet, and at least one second air outlet. The fan has a wind outlet facing the first air outlet. One part of the projection module is located between the wind outlet and the first air outlet, and one part of a heat dissipating airflow provided by the fan flows from the wind outlet to the first air outlet. The stopper wall structure is connected to the fan, and the stopper wall structure and one part of the housing define at least one air guiding channel. The other part of the projection module is located in the air guiding channel, and the other part of the heat dissipating airflow is guided by the air guiding channel to flow toward the second air outlet.
