SYSTEM OF HEAT CONTROL FOR ELECTRONIC DISPLAY Russian patent published in 2014 - IPC G12B15/02 G03B21/16 H05K7/20 

FIELD: heating.

SUBSTANCE: invention relates to cooling systems, and, in particular, to cooling systems for electronic displays. In a cooling unit for an electronic image unit and a display unit that comprises it, in some versions of realisation they use ambient gas for cooling of power supply modules and/or the image unit (sometimes back lighting). In other versions they use a closed circuit of circulating gas, which passes along the front surface of the image unit and via a heat exchanger. The open circuit passes via the heat exchanger and extracts heat from the circulating gas. Atmospheric air may be used as ambient gas. For cooling of the rear section of the image unit or back lighting with the help of ambient gas they may use a non-obligatory additional channel. In some versions of realisation they also use heat-conducting plates and ribs to distribute heat and to exclude hot points in the display.

EFFECT: improved working characteristics of components of electronic displays and their increased service life due to prevention of high oscillations of temperature in use of electronic displays in external environments under conditions of direct sunlight or under other heavy thermal conditions.
