Said cooler thermally connected with said electronic component. Each of said heatsinks comprises inflow and outflow openings, and thermally connected heat exchanging means and a base. Said double inlet centrifugal blower is located between said heatsinks thus each of said outflow openings is coincided with said closest inlet, so cooling air flows through said inflow openings, said heat exchanging means, said outflow openings and said inlets of said blower in a series way. Said base of at least one of said heatsinks is thermally connected with said electronic component.

Abstract: An at least partially moveable motor-vehicle outer skin is already known per se. An actuator formed of a polymer and/or ion-exchanging and/or other material exhibiting various conformations is provided so that the outer skin can be moved. This material is moveable as a result of physical or chemical effects. The novel outer skin of a motor vehicle requires no expensive tools for the production thereof. The flat section of the outer skin of the bodywork of a motor vehicle is made of a flexible material. A flexible material such as material for convertible top covers is easily moveable yet the surface thereof cannot be increased. This material is tensed at least over one part of the rib of the motor vehicle, e.g. over a space frame. At least one mechanically moveable adjusting element is provided beneath or on top of the edge of the section enabling the outer skin to be deformed. The adjusting element is normally connected to the rib of the motor vehicle.

The heatsink comprises a base and heat exchanging means made as flat disks, fins or flat plates. The base provides thermal contact with the electronic device and the heat exchanging means. The cross flow blower comprises a drum type impeller with an axis of rotation substantially normal to the base. The flat disks substantially perpendicular to the axis of rotation and located inside of the drum type impeller. The fins or flat plates substantially perpendicular to the axis of rotation and located outside of said drum type impeller. The heatsink further comprises heat-spreading means that provide thermal contact between the base and the flat disks and flat plates. The heat-spreading means may be heat-pipes.

Abstract: A multiple impeller flow inducing device in which driver coils are intermittently energized in timed relation to rotation of the impellers to interact with permanently magnetized portions of the impeller to rotate the same. The impellers can be rotated in opposite directions or in the same direction. A two section impeller construction allows each section to be magnetized in opposite pole orientation and when assembled creating alternate pole orientations of successive portions, arcuate segments forming a shroud or the type of blades can be magnetized to provide the impeller magnetized portions. Stator guide vanes can be interposed between successive impellers.
