Kind Code:
A
Abstract:
To provide a light source device, a projector, and a cooling plate that can improve cooling efficiency.SOLUTION: A light source device comprises: a light source module; a plurality of heat receiving plates that is connected with the light source module; and a cooling plate that is connected with the plurality of heat receiving plates and has cooling liquid circulating therein. The cooling plate includes an inflow part, an outflow part, an upstream side circulation part in which the cooling liquid flowing in from the inflow part circulates in a second direction orthogonal to a first direction, a downstream side circulation part in which the cooling liquid circulating in the upstream side circulation part circulates in a direction opposite to the second direction, and a plurality of heat transfer parts that is provided in at least one of the upstream side circulation part and the downstream side circulation part and is arranged side by side in the second direction. The plurality of heat transfer parts has a plurality of fins that extends in the second direction and is arranged in the first direction, and a plurality of channels that is provided between the plurality of fins. The plurality of heat receiving plates is arranged along the second direction. The plurality of heat transfer parts is separated from each other between the plurality of heat receiving plates in the second direction.SELECTED DRAWING: Figure 8
