    摘要: A heat-dissipating device used in a projection display apparatus with an air outlet includes a fence module, at least one resilient member, and a shape memory alloy module. The fence module is disposed at the air outlet and includes at least one guiding plate with a pivot. The resilient member exerts a first force on the guiding plate to enable the guiding plate to rotate on the pivot, and the shape memory alloy module deforms when heated to exert a second force on the guiding plate to enable the guiding plate to rotate on the pivot.
