Patent ID: 7481263

Claim:
A cooling apparatus having a cooling structure comprising: at least one surface area for introducing heat, and a cooling member that is connected to the cooling structure in a heat-conducting manner, wherein the cooling member is moveable so as to generate an air flow by means of the movement of the cooling member, the air flow supporting heat emission from the cooling member to the environment, wherein the cooling member is fixedly connected to a shaft and the shaft is rotatably supported in the cooling structure, the cooling structure comprises a container that is filled with a high heat-conducting medium, the shaft extends into the container and is fixedly connected to a rotating member within the container; and an air guiding device to direct the air flow, wherein the air guiding device comprises a cover plate that separates an air suction side and an air release side, the cover plate coaxially enclosing the shaft and providing a central aperture to define a flow channel in the vicinity of the shaft.
