A filter device which may include first and second filter elements allowing air to pass therethrough, and first and second filter holding members holding the first and second filter elements such that they are linearly connected side by side. The holding members being connected to be foldable in the position where the filter elements are connected.

Projector apparatus having a foldable filter device

A projector apparatus includes: an air intake port taking external air into the body of the apparatus; a duct guiding the external air taken in through the air intake port; a filter horizontally disposed in the duct; and a fan supplying the external air to a heat-generating part from underneath after the external air passes through the filter.

Projector apparatus having a cooling arrangement which enables the apparatus to have a low profile

A projection display apparatus includes an axial fan and a louver. The axial fan includes blades which are rotated to generate an airflow in an axial direction so that air is exhausted from a housing. The louver includes inclined plate portions which are inclined with respect to the axial direction, the inclined plate portions being arranged in a direction perpendicular to the axial direction at an airflow exit side of the axial fan, the louver being divided into a first area and a second area by a straight line which passes through an axial center of the blades, the inclined plate portions being inclined in different directions between the first area and the second area such that the inclined plate portions are inclined along the direction in which the blades are rotated.

Projection display apparatus comprising a louver with inclined and non-inclined portions

A blower for an electronic device includes a fan frame having an opening through which air passes for cooling the electronic device; a blade arranged in the opening of the fan frame; a motor configured to rotationally drive the blade; an attachment portion provided outside the opening of the fan frame, the attachment portion causing the fan frame to be attached to the electronic device; and a holder fixed to the electronic device and holding the attachment portion in a direction perpendicular to a rotational axis of the blade.
