PROBLEM TO BE SOLVED: To reduce the number of man-hours for maintenance and inspection, and perform stable cooling.SOLUTION: A video display device includes: a video processing unit for generating and displaying video signals; and a cooling mechanism for cooling object components to be cooled in the video processing unit. Also, the cooling mechanism includes heat receiving plates, heat conduction members, a cooler, and a circulation temperature controller. The heat receiving plates are attached on the object components to be cooled and receive heat generated in the object components to be cooled. The heat conduction members conduct the heat of the heat receiving plates. The cooler cools the heat conducted by the heat conduction members through a cooling liquid. The circulation temperature controller circulates the cooling liquid between the cooler and itself while performing control so as to keep the temperature of the cooling liquid at a constant temperature. |
