Abstract: Provided is a sheet-type heat pipe that has a sufficient heat transport capability and can be effortlessly installed in a thin chassis. The sheet-type heat pipe is made of a sealed container formed by stacking and joining together at least two etched sheet bodies formed as metal foil sheets. Particularly, etching or pressing is performed on the surface of the sheet bodies to join at least two sheet bodies such that fine concavities and convexities can be formed on the inner surface of the container and the sheet-type heat pipe with a sufficient heat transport capability can thus be obtained even when the sealed container is thinly formed with its thickness not larger than, e.g. 0.5 mm. More particularly, since the thickness of the container is thinly formed, the sheet-type heat pipe of the present invention can be effortlessly installed in a thin chassis of a mobile terminal.

Abstract: Provided is a mobile terminal capable of allowing a heat generating component such as a CPU to make best use of its capabilities. The sheet-shaped heat pipe, according to the present invention, is provided either between the rear surface of the touch panel and motherboard, or between the one and the battery pack. In this case, since the sheet-shaped heat pipe is arranged opposite to the rear surface of the touch panel which is a part of the chassis of the mobile terminal, a favorable heat diffusion from the heat generating components such as the CPU to a large area on the chassis can be achieved through these sheet-shaped heat pipe, thus allowing the heat generating component such as the CPU to make best use of its capabilities.

Abstract: Provided is a sheet-type heat pipe that has a sufficient heat transport capability and can be effortlessly installed in a thin chassis. The sheet-type heat pipe is made of a sealed container having a thickness of not larger than 0.5 mm. This container is formed by stacking and diffusion-joining together etched sheet bodies. Particularly, etching is performed on one side surface of each of the sheet bodies such that fine concavities and convexities can be formed on the inner surface of the container and the sheet-type heat pipe with a sufficient heat transport capability can thus be obtained even when the thickness of the container is not larger than 0.5 mm. More particularly, since the thickness of the container is formed to not larger than 0.5 mm, the sheet-type heat pipe can be effortlessly installed in a thin chassis such as that of a mobile terminal.

Abstract: There is provided a cooling device not affected by gravity by exerting a strong capillary attraction to be hard to deteriorate in transportation function. Unidirectionally-aligned copper fiber assembly 8 is mounted, by a sintering process, on an inner wall of a heat pipe 3 along the longitudinal direction of the heat pipe 3. Therefore, by a strong capillary attraction caused by fine copper fiber assembly 8, purified water can be transported without being affected by gravity. A flow volume just enough for the purified water to be prevented from drying out by its evaporation can be maintained, thus making it hard for a function in the transportation of the purified water to be deactivated. Further, the unidirectionally-aligned copper fiber assembly 8 is mounted along the longitudinal direction of heat pipe 3 and hence the purified water smoothly flows in the longitudinal direction of heat pipe 3.

Abstract: A fan motor with an increased amount of air drawn in toward fan blades so as to obtain a desirable airflow characteristic. A fan motor includes a rotor and a plurality of fan blades provided radially therefrom. Each fan blade is provided with an air intake part on a proximal side and a radial part on a distal side, including a first front surface on the former side and a second front surface on the latter side. The first and second front surfaces have different curvatures. Thus, air F can be impelled out toward a perimetric direction, and at the same time the intake of air toward the fan blades is promoted. Accordingly, the amount of air to be drawn in toward the fan blades is increased, thereby obtaining desirable airflow characteristic.

Abstract: A spatula heating apparatus with excellent usability which overcomes drawbacks inherent to conventional gas burner type and electro-thermal type apparatuses. A spatula heating apparatus for heating spatulas 9, 9a for wax molding includes a heating coil 8 for induction-heating of spatulas 9, 9a, a heating amount setting switch 5, and an inverter control circuit 21 for supplying high frequency current to the heating coil 8 to perform heating at a preset heating amount. When high frequency current is applied to the heating coil 8, the spatulas 9, 9a are heated at the preset heating amount through electromagnetic induction.

Abstract: A fan motor with an improved inhaling structure so as to enhance ventilation efficiency and performance, as well as cooling performance. An outer housing member 7 has a respective face opposite to a drive unit 11. An intake hole 13 of an arbitrary diameter is provided in a first face of the outer housing member 7, while another intake hole 15 of an arbitrary diameter is provided in a second face thereof. Both intake holes 13 and 15, however, are formed to have a larger diameter than the diameter of a rotor 4 defined by the peripheral side face thereof, thus enabling air to be drawn in directly to the respective faces of the fan blades 3, without being hindered by the rotor 4. Moreover, the intake holes 13 and 15 are formed to define a certain portion in which the air is drawn in from one side of a fan 5 only.

Abstract: A cooling unit having a heat-receiving portion and a heat-exchanging portion. The heat-receiving portion is thermally connected to a heat-generating component. The heat-exchanging portion receives heat from the heat-receiving portion, at a position different from the position where the heat-generating component is provided. A part of the heat generated by the heat-generating component and transmitted to the heat-receiving portion is transferred to the heat-exchanging portion through a heat pipe. A fan device is provided between the heat-receiving portion and the heat-exchanging portion.

Abstract: A fan motor with an improved inhaling structure so as to enhance ventilation efficiency and performance, as well as cooling performance. An outer housing member 7 has a respective face opposite to a drive unit 11. An intake hole 13 of an arbitrary diameter is provided in a first face of the outer housing member 7, while another intake hole 15 of an arbitrary diameter is provided in a second face thereof. Thus, a substantial amount of air is taken in from the two faces of the outer housing member 7, thereby drastically improving the ventilation efficiency. Even though an inhaling passage is not ensured substantially on a top face of the outer housing member 7, the air is able to be inhaled even through a slight clearance due to the other intake hole 15, thus improving the cooling performance. The air taken in from the intake holes 13 and 15 of the outer housing member 7 is smoothly discharged toward the exhaust direction of a fan 5, without striking on walls of a casing 1 and a cover 12.
