Light source cooling device including holding part located on surface of a case and projection type display device

摘要

Provided is a light source cooling device that includes: a case in which exhaust port (112) is formed; ventilation device (102) that has a blowing port blowing air and that is located in the case; flow path component (301); light source (101); and holding part (121) disposed in an inner surface of case (108). Flow path component (301) constitutes flow path (403) for guiding air from ventilation device (102) to exhaust port (112) in the case. Light source (101) is located in flow path (403). Flow path component (301) includes a first opening and a second opening. The first opening is connected to exhaust port (112), while the second opening is connected to the blowing port of ventilation device (102). An outer surface of flow path component (301) is held by holding part (121).

主权项

1. A light source cooling device, comprising:
a case in which an exhaust port is formed; a ventilation device that includes a blowing port for blowing air and that is located in the case; a flow path component constituting a flow path guiding the air from the ventilation device to the exhaust port in the case; a light source located in the flow path; a holding part located on an inner surface of the case,
wherein the case includes an opening for accessing the light source, the opening being aligned with a position in the case where the light source is located,wherein a first cover for covering the opening for accessing the light source is provided,wherein the flow path component includes a first opening and a second opening,wherein the first opening is connected to the exhaust port of the case while the second opening is connected to the blowing port of the ventilation device, andwherein an outer surface of the flow path component is held by the holding part provided in a different region from a region in which the first cover is provided; and a space formed by the outer surface of the flow path component, the inner surface of the case, and the holding part, wherein the holding part is formed in a frame shape for surrounding the space.
