An image projection apparatus includes: a light source (160); an exhaust fan (7) configured to discharge air in the apparatus to outside of the apparatus; and a plurality of wind guiding walls (82a, 82b, 82c, and 82d) extending in a direction perpendicular to an exhaust direction of the exhaust fan (7), and configured to guide air that has cooled the light source (160). The wind guiding walls (82a, 82b, 82c, and 82d) are arranged side by side in a rotation axis direction of the exhaust fan (7). At least a downstream portion of each of the wind guiding walls (82a, 82b, 82c, and 82d) in an air flowing direction after cooling the light source (160), is gradually inclined so as to move away from the exhaust fan (7) in the rotation axis direction of the exhaust fan (7), toward downstream in the air flowing direction.

An image projector (1) includes a first housing (4), a second housing (5), a power transmitter (7), and a heat transporter (6a, 6b). The first housing (4) includes a light source (13) to emit light, an image display (29) to form an image with the light, an illumination optical device (50) to direct the light to the image display (29), and a projection optical device (3) to project the image. The second housing (5) includes a power source (8) to supply power, a heat dissipator (10) to dissipate heat, and a cooler (11) to exhaust the heat. The power transmitter (7) and the heat transporter (6a, 6b) couples the first housing (4) and the second housing (5) to each other to transmit the power from the second housing (5) to the first housing (4), and to transport heat from the first housing (4) to the second housing (5), respectively.
