ABSTRACT:
To improve the heat protection of an electronic device (7) in the case of heat radiation coming from the outside, for example solar rays, lateral radiation reflectors (12, 13; 16, 17) of 1 mm-thick aluminium plate polished on both sides and degreased are arranged between the electronic device and the walk (20, 21) of a heat protection casing (1) which laterally surrounds the electronic device. In addition, upper radiation reflectors (14, 15) are provided between the coverplate of the electronic device (7) and a coverplate (4) of the heat protection casing (1), a ventilation opening (18) remaining to the lateral radiation reflectors. In the sidewall of the heat protection casing (1), lower and upper ventilation slots (5,6) are arranged by means of which a chimney effect is achieved in the interior of the heat protection casing. In addition, a bottom plate (2) of the heat protection casing (1) can exhibit cooling openings (3).
