Embodiment Construction

[0016] Hereinafter, a projector according to an embodiment of the present invention will be described with reference to the drawings. In addition, the scope of the present invention is not limited to the following embodiments, and can be arbitrarily changed within the scope of the technical idea of ​​the present invention. In addition, in the following drawings, in order to make each structure easy to understand, the scale, number, etc. in each structure may differ from the scale, number, etc. in an actual structure.

[0017] The Z-axis direction appropriately shown in each figure is an up-down direction in which the +Z direction (first direction) is on the upper side and the −Z direction is on the lower side. The X-axis direction and the Y-axis direction are horizontal directions perpendicular to the Z-axis direction, and are directions perpendicular to each other. In the following description, the direction parallel to the Z-axis direction is called the vertical direction Z...

Abstract

Provided is a projector which solves the problem that in a structure in which air is taken into an exterior housing from the bottom of the exterior housing, the distance from a fan to an object to be cooled is likely to become longer, and sometimes it is difficult to appropriately cool the object to be cooled. One aspect of a projector according to the present disclosure includes an exterior housing, a first fan, and a first circulator. The exterior housing has a first wall portion, a second wall portion located in a direction opposite to a first direction with respect to the first wall portion, and a third wall portion facing a second direction. The second wall portion has an introduction port, and the third wall portion has a discharge port. The first circulator connects the introduction port and a first suction port of the first fan to each other. A cooling target is located in the first circulator in a direction intersecting with a direction in which air flows from the introduction port to the first suction port.

Description

technical field [0001] The present invention relates to projectors. Background technique [0002] For example, as disclosed in Patent Document 1, there is known a projector having a projection optical device having a reflection member for reflecting light. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2013-041134 [0004] In the above-mentioned projector, in order to cool the cooling object arranged inside the exterior case of the projector, it is conceivable to install a fan at the bottom of the exterior case and take in air from the bottom of the exterior case into the interior of the exterior case. Structure. However, in this structure, the distance from the fan to the object to be cooled tends to be long, and it may be difficult to properly cool the object to be cooled. Contents of the invention [0005] One aspect of the projector of the present invention provides a projector having a cooling object, characterized in that the projector includes: a light...
