Claim:
A heat-dissipating structure of a housing of a projection device, the housing comprising a surface, the surface defining an opening therein, the heat-dissipating structure being embedded within the opening, the heat-dissipating structure comprising: a plurality of metal slats equidistantly spaced to form a plurality of air channels therebetween; a plurality of strip-shaped connection members, the alternating two adjacent slats being bridged by two strip-shaped connection members at a same side edge thereof; and a supporting frame comprising two strips, the two strips being configured for maintaining the connection members adjacent thereto, the metal slats being angled with respect to the supporting frame so that the metal slats are substantially parallel to each other and the air channels are substantially aligned to the flow direction of air flow generated with the projection device, wherein the height of each of the plurality of metal slats ranges from about 11.5 to about 12.5 mm, the thickness of the metal slats ranges from about 0.45 to about 0.55 mm, and the included angles between each of the plurality of metal slats and the supporting frame is in the range of about 48 to about 57 degrees.
