Projecting apparatus

A projecting apparatus comprising:

• a chassis comprising:
• at least four side walls, wherein a first side wall is opposite to a third side wall and a second side wall is opposite to a fourth side wall, a first corner is formed by the first side wall and the second side wall, a second corner is formed by the second side wall and the third side wall, a third corner is formed by the third side wall and the fourth side wall, and a fourth corner is formed by the fourth side wall and the first side wall;
• a first air outlet located on the first side wall and close to the fourth corner;
• a second air outlet located on the second side wall and close to the second corner;
• and
• a first air inlet close to the third corner;
• an optical engine disposed within the chassis and close to the first corner, wherein the optical engine further comprises a light source module and an imaging module, the imaging module further comprises a light valve and a projection lens, and the projection lens is disposed on the first side wall;
• a first fan set disposed in the chassis and close to the first air outlet, wherein the first fan set is configured to drive exterior air to flow into the chassis to form a first air flow via the first air inlet, and the first air flow flows out of the chassis via the first air outlet;
• and
• a second fan set disposed within the chassis and close to the second air outlet, wherein the second fan set is configured to drive exterior air to flow into the chassis to form a second air flow via the first air inlet, the second air flow flows out of the chassis via the second air outlet, and a flow direction of the first air flow at the first air outlet is perpendicular to a flow direction of the second air flow at the second air outlet.
