The evaporator includes a housing having a reservoir configured to retain a working fluid in a liquid phase flowing inside, a wick disposed in the housing, and transporting the working fluid in the liquid phase, and a groove member having a plurality of flow channels through which the working fluid changed in phase from the liquid phase to the gas phase flows, the groove member being coupled to the wick. The wick has a plurality of through holes which penetrate the wick along a first direction from the reservoir toward the groove member, the through holes being configured to transport the working fluid in the liquid phase retained in the reservoir in the first direction. | 2020-09-17 |
20200292927 | PROJECTOR - A projector includes a light source, a light modulator, a projection optical apparatus, a cooler configured to cool a cooling target based on transformation of a refrigerant into a gas, and a dustproof enclosure accommodating the cooling target. The cooler includes a refrigerant generator configured to generate the refrigerant and a refrigerant sender configured to send the generated refrigerant toward the cooling target. Part of a wall part that forms the dustproof enclosure is a refrigerant transmissive section that maintains dust resistance of the dustproof enclosure and allows transmission of the refrigerant into the interior of the dustproof enclosure from the exterior thereof. | 2020-09-17 |
20200292928 | LIGHT EMITTING APPARATUS AND PROJECTOR - A light emitting apparatus including a base, a light source, and a plurality of columnar sections that are provided at the base and each include a first phosphor that emits light when irradiated with light emitted from the light source, in which the light source radiates the light to the columnar sections obliquely with respect thereto. | 2020-09-17 |
