Title:
PROJECTOR
Document Type and Number:
WIPO Patent Application WO/2017/122409
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a projector capable of reducing mechanical stress to an optical panel, said mechanical stress being caused by vibration of a cooling liquid tube in which a cooling liquid for cooling the optical panel is circulated.
This projector is provided with: optical panels (60R, 60G, 60B); heat receiving plates (30a, 30b, 30c), each of which has a cooling liquid path inside, and receives heat generated by each of the optical panels; flexible cooling liquid tubes (21a, 23a, 23b, 25a, 25b, 27a) which are connected to the heat receiving plates; and a supporting section, to which the cooling liquid tubes extending from the heat receiving plates are connected. In the cooling liquid tubes, at least connecting portions to the heat receiving plates, and connecting portions to the supporting section are disposed in the disposition direction of a flat surface of each of the heat receiving plates.
