A rotary gyroscope includes a base plate, an intermediate structure, including a driven element floating over the base plate and supported by a driving supporter radially extending therefrom, the driven element performing an oscillating motion with respect to a first axis, which is normal to a center plane thereof, a driving electrode driving the driven element, and a sensing element disposed in the driven element and connected to the driven element by a sensing connector to oscillate together with the driven element and concurrently to perform a sensing motion with respect to a third axis, which is normal to the first axis and any second axis, which is parallel to a center plane, due to a Coriolis force when an angular velocity is inputted from the second axis, and a cover covering the intermediate structure and having a sensing electrode to detect the sensing motion of the sensing element.

An evaporator of a capillary pumped loop (CPL) cooling apparatus having a fine wick structure is provided. The evaporator having a flat board shape, of a capillary pumped loop (CPL) cooling apparatus includes a coolant storing part for storing in-flowing coolant from the condenser and collecting a uncondensed gas contained in the in-flowing coolant in an upper space, a cooling part for cooling the heating body through vaporization of the coolant, and superstructure and substructure combined with each other, for defining a channel region in which the coolant flows from the coolant storing part to the cooling part by a capillary action. In this case, the substructure includes a first substructure used as a substrate and a second substructure formed along a border of the substrate, or includes first through third segments equal to the first and second substructures. The channel region is formed between the second segment and the superstructure, and a pumping means formed of patterns that are formed so that the capillary action is generated in the coolant, or a porous material is included in the channel region.

Evaporator of CPL cooling apparatus having fine wick structure

A flat evaporator is provided. In the evaporator, a common chamber formed on a substrate with a predetermined diameter and depth for containing a coolant is divided into a vaporization cavity region, a capillary region surrounding the vaporization cavity region, and a manifold region surrounding the capillary region. The capillary region has a capillarity generator capable of generating capillary action, and a top plate is configured to include an exhaust unit including a gas collector to exhaust a gas coolant generated in the vaporization cavity region. The evaporator can be implemented as a small and thin cooling device for performing cooling without external power. Furthermore, the evaporator can effectively prevent degradation of fluid flow force due to coexistence of gas and liquid by isolating a liquid coolant from a vaporized coolant by a capillary region, thereby significantly improving heat exchange characteristics.

Furthermore, the evaporator can effectively prevent degradation of fluid flow force due to coexistence of gas and liquid by isolating a liquid coolant from a vaporized coolant by a capillary region, thereby significantly improving heat exchange characteristics.

A plate type condenser used in a cooling system is provided. The plate type condenser includes a casing for defining an upper space into which a gaseous refrigerant flows and is cooled, a lower space for accommodating a liquid refrigerant into which the gaseous refrigerant is condensed, and a connecting portion through which the upper and lower spaces communicate with each other. The casing substantially has a plate shape. A refrigerant inlet is installed at an upper portion of the casing to communicate with the upper space. A refrigerant outlet is installed at a lower portion of the casing to communicate with the lower space. A first adiabatic slit for separating the walls of the casing is formed between the upper space and the lower space except at the connecting portion. Accordingly, since the first adiabatic slit prevents heat in the upper space from being conducted to the lower space through the walls of the casing, a liquid refrigerant in the lower space can be satisfactorily cooled without using an additional subcooler.
