Abstract
A method for cooling a display assembly includes forcibly circulating gas about an airflow pathway extending within a housing and surrounding an image assembly. Forcibly ingesting ambient air into the housing through an intake, passing the ingested ambient air within the housing in a manner which provides thermal interaction with the circulating gas in said airflow pathway, and exhausting the ingested ambient air from the housing through an exhaust to cool the circulating gas.
Claims20
A method for cooling a display assembly comprising the steps of:
- forcibly circulating gas about an airflow pathway extending within a housing, wherein said airflow pathway surrounds an image assembly;
- and
- forcibly ingesting ambient air into said housing through an intake, passing said ingested ambient air within said housing in a manner which provides thermal interaction with said circulating gas in said airflow pathway, and exhausting said ingested ambient air from said housing through an exhaust in said housing to cool the circulating gas.
A method for cooling a display assembly comprising the steps of:
- forcibly circulating gas about an airflow pathway extending within a housing, wherein said airflow pathway surrounds an image assembly and comprises:
- a channel located between a forward surface of the image assembly and an inner surface of a front display surface;
- and
- a rear chamber located behind the backlight assembly and forward of an interior, rear surface of said housing;
- forcibly ingesting ambient air into said housing through an intake, passing said ingested ambient air through a second airflow pathway extending within the housing adjacent to, and separate from, said rear chamber of said airflow pathway to provide thermal interaction with said circulating gas in said rear chamber of said airflow pathway and said ambient air in said second airflow pathway, and exhausting said ingested ambient air from said housing through an exhaust in said housing to cool the circulating gas;
- and
- providing a filter at said housing to prevent contaminants and dust within said ambient air from entering at least said front chamber of said airflow pathway.
A method for cooling a display assembly comprising the steps of:
- activating a first set of one or more fans to forcibly circulate gas about an airflow pathway extending within a housing, wherein said airflow pathway surrounds an image assembly and comprises:
- a channel located between a forward surface of the image assembly and an inner surface of a front display surface;
- and
- a rear chamber located behind the backlight assembly and forward of a rear surface of said housing;
- activating a second set of one or more fans to forcibly ingest ambient air into said housing through a filtered intake, pass said ingested ambient air through a second airflow pathway extending within the housing separate from said airflow pathway and in thermal communication with said rear chamber of said airflow pathway, and exhaust said ingested ambient air from said housing through an exhaust in said housing.
