Beschreibung
Zusammenfassung:	A light source device with a heat dissipation function applied to a projector includes a light source, a heat conduction plate, a flow guide member, and a fluid driving device. The heat conduction plate is disposed on the light source and has a hole structure corresponding to a hot spot region of the light source. The flow guide member has a guide channel corresponding to the hole structure. The guide channel has wide inlet and a narrow outlet. The flow guide member is disposed on the heat conduction plate to make the narrow inlet aligned with the hole structure. The fluid driving device is disposed on the flow guide member and communicated with the wide inlet. The fluid driving device drives fluid to flow from the wide inlet into the guide channel and then pass through the narrow inlet for generating an impact flow toward the hole structure.
