SOLUTION: The light source device 100 comprises a light source of a lamp 50, a heat transporting device 60 of phase change coolant type, a jet flow generator 20 which generates a combination of jet flows. Heat generated by the lamp 50 is transported by the heat transporting device 60 up to the position distant from the lamp 50, the combination of jet flows is supplied by the jet flow generator 20, and heat is radiated at that position. Especially, since the jet flow generator 20 is used, cooling performance can be improved. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To restrain vibration of flickering in all areas of an image plane by providing a vibration control effect to the whole surface of an aperture grill. SOLUTION: This vibration control device 41 comprising a band-shaped metal thin plate 29 is brought contact with a protrusively curved surface side of an aperture grill 25 in the direction orthogonal to the longitudinal direction of the portions. The aperture grill 25 is formed of a plurality of slits and the tape portions parallel to each other that are formed alternately, and is stretched between protrusively curved sides of curved members 23, 23 so that tension is given to the longitudinal direction of the tape parts. In this device 41, both longitudinal end sides of the band-shaped metal thin sheet 29 are contacted with the aperture grill 25 in an area larger than that of its central portion in the longitudinal direction.

PROBLEM TO BE SOLVED: To provide a method of manufacturing an inexpensive thermal transport device which is efficiently manufactured in the small number of processes. SOLUTION: In the method of manufacturing the thermal transport device, a capillary member 5 with its thickness thicker than that of a frame member 2 is placed on an inner surface 11 of a lower plate member 1. Then, the frame member 2 is placed on the inner surface 11 of the lower plate member 1, and an upper plate member 3 is placed on the capillary member 5. A crushing amount G is provided between the frame member 2 and the upper plate member 3 based on difference between thickness of the capillary member 5 and thickness of the frame member 2. The lower plate member 1 is diffusion-joined to the frame member 2, and the upper plate member 3 is diffusion-joined to the frame member 2. Then, the capillary member 5 is compressed by the crushing amount G. As the capillary member 5 has elasticity, a part of pressure P is absorbed, and pressure P' smaller than the pressure P is applied on the lower plate member 1 from the capillary member 5. The inner surface 11 of the lower plate member 1 and the capillary member 5 are diffusion-joined by the pressure P'. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a heat spreader attaining high condensing efficiency without increasing a size, electronic equipment with the heat spreader, and a method of manufacturing the heat spreader. SOLUTION: A pillar 60 is formed on a condensation side plate 41. A nano material such as a carbon nano-tube is generated on a surface of the condensation side plate 41 with the pillar 60 formed and surfaces (a side face and an end 61) of the pillar 60 so that its leading end directs downward. The nano material formed at the end 61 of the pillar 60 is removed. The remaining nano material forms a condensation part 20. The end 61 of the pillar 60 is joined with an area of an evaporation side plate 42 on which no evaporation part 70 is formed to manufacture the heat spreader 10 with the condensation part 20 formed on the condensation side plate 41 and side faces of the pillar 60. The nano material is not formed on joined part of the pillar 60 with the condensation side plate 41 and the evaporation side plate 42, so that the adhesiveness of these parts is increased to increase the strength of the heat spreader 10.

Abstract:
PROBLEM TO BE SOLVED: To provide a heat spreader can improve flow efficiency of a working fluid from a condenser portion to an evaporation portion, and to provide an electronic apparatus equipped with the heat spreader. SOLUTION: The working fluid in a liquid phase is distributed through a liquid phase flow path 40 by gravity from a condenser portion 30 to an evaporation portion 20, arranged at a position lower than the condenser portion 30. The liquid phase flow path 40 is made of a nanomaterial, having hydrophobicity on the surface. Thus, the contact angle of a liquid refrigerant is kept large and flow path resistance is kept low. As a result, the flow efficiency of the working fluid in the liquid phase, from the condenser portion 30 to the evaporation portion 20, is improved without causing biasing in the distribution of the working fluid in the liquid phase. Accordingly, since the supplied amount of the liquid refrigerant to the evaporation portion 20 is not decreased, circulation of the refrigerant is not interfered, and stability of the operation is obtained.

PROBLEM TO BE SOLVED: To provide a heat transfer device capable of reducing a manufacturing cost, electronic equipment loading the heat transfer device, and a manufacturing method for the heat transfer device. SOLUTION: The heat transfer device 10 is constituted by laminating a central plate material 3, spacers 2 and 4, side plate materials 1 and 5, and a clad material 6 configuring a heat absorber and the clad material 7 configuring a heat dissipator. Openings 2a and 4a formed to the spacers 2 and 4 respectively are used as flow paths for a working fluid. Accordingly, since the heat transfer device can be formed without depending upon a fine working technique such as a photolithography as seen in conventional devices, the manufacturing cost can be held down.
