Abstract
In at least one embodiment of the disclosure, a liquid-cooling device to cool an optical element in a projector includes 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 is configured to circulate the cooling liquid. Liquid circulation members are configured to connect the optical element holding member and the liquid pumping unit and to define a flow channel of the cooling liquid. A thermoelectric conversion element has a heat-absorbing surface and a heat-radiating surface. The thermoelectric conversion element is connected to the liquid-cooling device to transfer the heat from the cooling liquid to the heat-absorbing surface.
