Abstract
Official abstract text for this publication.
A video display device includes: a video processing unit including a light source and optical components, which generates and displaying video signals; and a cooling mechanism unit cooling the light source and the optical components, wherein the cooling mechanism unit includes an air cooling fan generating cooling air for cooling the optical components to be circulated in the device, a heat exchanger arranged in a flow path of the circulating cooling air, performing heat exchange of the cooling air obtained after the cooling of the optical components from a high temperature to a low temperature, a cooler cooling heat generated in the light source and heat generated in the heat exchanger by a cooling liquid, and a circulating thermal regulator circulating the cooling liquid with respect to the cooler while managing a liquid temperature of the cooling liquid so as to be a constant temperature.
First claim
Opening claim text (preview).
What is claimed is: 1. A video display device comprising: a video processing unit including a light source, an illumination unit and an optical block; and a cooling mechanism unit configured to cool the light source, the illumination unit and the optical block, wherein the cooling mechanism unit includes an air circulating system that does not use outside air for cooling, including at least one air cooling fan configured to circulate cooling air in the device for cooling the…
