Patent number: 8128359Abstract: An air fan module and a flow directing blade assembly thereof aim to reduce noises generated during operation of the air fan caused by friction between blades and air and improve cooling efficiency. The air fan module includes a fan frame which has an air inlet, an air outlet and a housing space formed between them to hold a flow directing blade assembly. The flow directing blade assembly has an axis and a plurality of blades mounted onto the axis. Each blade has a first end surface and a second end surface. The first and second end surfaces have respectively a plurality of first flow directing portions and second flow directing portions that are respectively spaced from each other and formed in an asymmetrical manner. Air can form steady airflow by channeling of the first flow directing portions and the second flow directing portions of two neighboring blades.Type: GrantFiled: March 12, 2009Date of Patent: March 6, 2012Assignees: Listan Asia Inc., Listan GmbH & Co., KGInventor: Chi-An Chen

Patent number: 8043049Abstract: An air fan damping structure is installed on an air fan which has a fan frame. The fan frame has an air inlet, an air outlet and a housing space between them to hold a fan blade assembly. The damping structure includes a first buffer and a holding member located on the fan frame. The first buffer is hollow and has a through hole, and a first anchor portion to form an anchor relationship with a second anchor portion formed on the fan frame. The holding member has an inserting portion to run through the through hole and a depressing portion connecting to the inserting portion to receive a force to allow the inserting portion to run through the through hole. The inserting portion and the through hole have respectively a first retaining portion and a second retaining portion to form a retaining relationship.Type: GrantFiled: March 12, 2009Date of Patent: October 25, 2011Assignees: Listan Asia Inc., Listan GmbH & Co.Inventor: Chi-An Chen

Publication number: 20100243822Abstract: A power supply cable outlet angle adjustment structure aims to overcome shortcomings of the conventional power supply that cannot adjust cable outlet angle to mate connecting electronic devices. The power supply has an opening on a body to allow a power cable to be threaded through and a pivotal turnable adjustment member connected to the opening. The adjustment member has a cable outlet to allow the power cable to be drawn out. The power cable can be pivotally turned synchronously with the adjustment member at a selected outlet angle to mate different installing locations of the electronic devices to facilitate connection between them.Type: ApplicationFiled: March 25, 2009Publication date: September 30, 2010Applicants: LISTAN ASIA INC., LISTAN GMBH & CO.
