Abstract: A fan for generating a cooling air flow has a fan wheel which is rotatably held on a support body. A fastening component having fastening openings for fastening the fan is connected to the support body. An elastic damping element is provided for damping the transmission of vibrations generated during rotation of the fan wheel. The elastic damping element is guided along a guiding device, which is formed between the support body and the fastening component. The elastic damping element and the guiding device are designed to be circumferential. Alternatively, the elastic damping element is designed as a plug-in element which is inserted through passage openings in the support body and the fastening component, as a result of which the support body and the fastening component are held at a distance from one another.

Abstract: Microstructure water cooling unit for cooling of an electrical or electronic component that already includes a flow diverter and a flow distributor which change the water flow from the inlet to the water chamber and create a harmonized water output in the injection plate which improves the cooling capability of the whole water cooling unit.

Abstract: Electro motor unit that consists of a rotor and a stator with an included electronic control unit which enables the electromotor to be reduced in the maximum rotation speed manually by the user, but still is controllable by the PWM-Signal from zero rotation to the manually set maximum rotation speed.

Abstract: Reverse flow microstructure water cooling unit for cooling of an electrical or electronic component which already includes an electrical pump which is placed above the middle of the bottom plate sucking the water out of the bottom micro fin cross structure and thereby generates micro turbulences which improve the cooling capability of the whole water cooling unit.
