HEAT RADIATION APPARATUS OF A TV SET TOP BOX CAPABLE OF EFFICIENTLY RELEASING HEAT OF A HEAT GENERATION ELEMENT TO OUTSIDE

摘要

PURPOSE: A heat radiation apparatus of a TV set top box is provided to improve radiation speed of heat transferred to a middle cover by spreading heat radiation materials on the upper side of the middle cover.;CONSTITUTION: A heat radiation apparatus of a TV set top box comprises a lower case(110), an upper cover(120) covering the upper side of the lower case, a middle cover(130) contacting with the outside, and a heat sink(140). A first contact surface(141a) contacts with a heat generation element(1) mounted on a substrate. A second contact surface(141b) contacts with the middle cover. A conductive plate(141c) is connected between the first contact surface and the second contact surface. The first contact surface and the second contact surface respectively comprise thermal conduction parts(142a, 142b). The heat sink is directly combined to the middle cover.;COPYRIGHT KIPO 2012
