Patent ID: 7817425

Claim:
A heat dissipating apparatus for a flat display panel device, the heat dissipating apparatus comprising: a chip contact plate formed at a surface of an IC chip and having heat conductivity, wherein the IC chip is configured to generate heat while driving a flat display panel, wherein the surface faces away from a chassis base which supports the flat display panel, and wherein a plurality of grooves are formed on the chip contact plate; and a heat discharging plate including a plurality of heat dissipating portions formed on the chip contact plate, wherein each of the heat dissipating portions includes i) a top which does not contact the chip contact plate and ii) two spaced sides, wherein each side comprises first and second ends opposing each other, wherein the first ends of each side extends from the top, wherein the second ends of each side contact the chip contact plate, wherein the top and the sides of each heat dissipating portion are configured to form a tapered heat dissipating portion, wherein each of the heat dissipating portions defines, in conjunction with a portion of the chip contact plate, a partially covered air passage, and wherein the heat discharging plate is configured to dissipate the generated heat at least via the partially covered air passage, wherein the heat discharging plate comprises a plurality of joining portions which contact the chip contact plate, wherein at least one of the plurality of joining portions interconnects adjacent heat dissipating portions, and wherein the plurality of grooves of the chip contact plate are configured such that the plurality of joining portions are pressed and snapped into the respective grooves in order to firmly couple the chip contact plate and the heat discharging plate, wherein at least one hole is defined on the top of each heat dissipating portion so that the heat discharging plate is further configured to dissipate the generated heat via the hole, and wherein the apparatus further comprises a heat conducting medium formed between the IC chip and the chip contact plate.
