Abstract
The present invention discloses a heat radiating device of an LCD projector, and the LCD projector has a fully sealed optical machine. The heat radiating device comprises an LED light source radiator, an efficient heat exchanger, external fans and an air guide cover. A window used for installing the efficient heat exchanger is formed in the bottom of a shell of the fully sealed optical machine. The efficient heat exchanger comprises a buckled Fin at a high temperature heat absorption side, a partition plate and sunflower sectional materials at a low temperature heat release side; and the buckled Fin, the partition plate and the sunflower sectional materials are sequentially pasted. The buckled Fin is located on an internal heat radiating air channel of the fully sealed optical machine; and the partition plate is formed in the bottom of the shell of the fully sealed optical machine.
