Abstract:
1. A projector comprising: an optical element holding member configured to allow a flow of a cooling liquid therein and to hold the optical element so as to transfer heat to the cooling liquid; a liquid pumping unit configured to circulate the cooling liquid; a plurality of liquid circulation members configured to connect the optical element holding member and the liquid pumping unit and to define a flow channel of the cooling liquid; a heat-receiving jacket disposed in the flow channel and having a plurality of flow channels which allow flow of the cooling liquid therein; a heat transfer member; a thermoelectric conversion element having a heat-absorbing surface connected to the heat-receiving jacket and a heat-radiating surface connected to the heat transfer member; a supporting member configured to fix the heat-receiving jacket and the heat transfer member; a baffle member configured to define an internal space with the supporting member and to house the heat transfer member in the internal space; and a first cooling fan configured to provide cooling air to the heat transfer member disposed in the internal space, wherein the supporting member includes an opening to fit the thermoelectric conversion element.
