Abstract
Disclosed is a cooling structure for a projection television, which keeps the inside of the projection television clean and effectively cools the heated projection television. The cooling structure for the projection television comprises a heat blocking unit for separating a lamp system generating superheat from the sealed inner space, a cooling fan for forcibly cooling the heat generated by the synthesis system within the sealed inner space, the cooling fan being formed adjacent to the synthesis system, and a radiating unit for exhausting the heat of the inner space to the outside, the radiating unit being formed on the upper part of the housing.
Claims10
A cooling structure for a projection television, said cooling structure comprising:
- an optical engine assembly including a lamp system, a synthesis system, and a lens system;
- a screen, a housing, and a back cover, said three elements being assembled, thereby forming an inner space;
- a heat-blocking unit including heat blocking ribs and heat blocking plates, said heat-blocking ribs and said heat-blocking plates contacting the perimeter of the lamp system, thereby separating the lamp system from the inner space;
- a sealing frame connected to the heat blocking unit, thereby forming a diaphragm for sealing the inner space in combination with the heat blocking unit;
- and
- a radiating unit including radiating holes for exhausting the heat of the inner space to the outside and a heat sink for covering the radiating holes and for contacting the air of inner space, said radiating holes being formed on the housing and said heat sink being thermal conductive.
A cooling structure for a projection television, said cooling structure comprising:
- an optical engine assembly including a lamp system, a synthesis system, and a lens system;
- a screen, a housing, and a back cover, said three elements being assembled, thereby forming an inner space;
- a sealing structure for radiating the heat generated by the lamp system to the outside and for sealing the inner space except for the lamp system;
- and
- a radiating unit including radiating holes for exhausting the heat of the inner space to the outside and a heat sink for covering the radiating holes and for contacting the air of inner space, said radiating holes being formed on the housing and said heat sink being thermal conductive.
A cooling structure for a projection television, said cooling structure comprising:
- a screen, a housing, and a back cover, said three elements being assembled, thereby hermetically sealing an inner space;
- a heat-blocking unit for separating a lamp system generating superheat from the sealed inner space;
- a cooling fan for forcibly cooling the heat generated by the synthesis system within the sealed inner space, said cooling fan being formed adjacent to the synthesis system;
- and
- a radiating unit for exhausting the heat of the inner space to the outside, said radiating unit being formed on the upper part of the housing.
