Abstract
An apparatus for mounting and cooling a flat screen during operation comprises a housing for accommodating the flat screen and further heat generating electric and electronic units, moreover thermal bridges for conducting the heat generated by at least the flat screen to a heat conductive rear wall of the housing. The rear wall is provided with at least one profile in a manner that a plurality of chimney-like cavities are formed on the rear side of the housing, which comprise in their lower end portion at least one opening for supplying cool air into each cavity, and at least one outlet opening in the upper end portion of each cavity for discharging heated air into the atmosphere.
Claims10
An apparatus for mounting and cooling a flat screen during operation, comprising a housing for accommodating the flat screen and heat generating electric and electronic units, and at least one thermal bridge for conducting the heat generated by these units to a heat conductive plate arranged at a rear side of the housing, said plate being provided with a profile for faster cooling of the plate, wherein
- the plate forms a rear wall of the housing, the profile forms a plurality of chimney-like cavities on the rear side of the housing, said cavities each comprising a lower end portion and an upper end portion, wherein in the lower end portion at least one opening for supplying cool air into the respective cavity is formed and in the upper end portion at least one outlet opening for discharging heated air from the cavity to the atmosphere is formed, and
- the rear wall of the housing comprises a plurality of through holes arranged adjacent to said cavities, said through holes serving for supplying air from said cavities into a space arranged between the heat generating units and the rear wall and for discharging heated air from said coats into said cavities, respectively.
An apparatus for mounting and cooling a flat screen during operation, comprising a housing for accommodating the flat screen, and comprising heat-generating electric and electronic units, and at least one thermal bridge for conducting the heat generated by these units to a heat conductive plate arranged at a rear side of the housing, said plate being provided with a profile for faster cooling of the plate, wherein
- the plate forms a rear wall of the housing, the profile is attached on the rear wall of the housing by means of screws and together with the rear wall forms a plurality of chimney-like cavities, which are arranged at mutual distance and have a substantially cartridge-like cross section with a rounded apex directed to the outside and each comprise a lower end portion and an upper end portion, wherein the lower end portion at least one opening Is formed for supplying cool air into the respective cavity and in the upper end portion at least one outlet opening is formed for discharging heated air from the cavity to the atmosphere,
- the rear wall of the housing comprises a plurality of through holes arranged in the area of the cavities, said through hales serving for supplying and discharging air into and from a space arranged between the heat generating units and the rear wall,
- the housing comprises a housing frame, and a thermal bridge of a heat-conductive material is formed on at least one position of a printed circuit board attached at the housing frame, with a plurality of heat generating components of the flat screen being arranged on the printed circuit board, and said thermal bridge being oriented towards the rear wall of the housing and contacting the rear wall in the operative condition, and
- the air located between the printed circuit board and a final front glass plate of the flat screen heated during operation of the screen is introduced via at least one channel into the space between the printed circuit board and the rear wall.
