Abstract: A power supply includes a bottom case, a top cover, a circuit board and a heat-dissipating fan. In this case, the bottom case and the top cover are fitted together to delimit an accommodating space. The circuit board is mounted on the bottom case and located within the accommodating space. The heat-dissipating fan includes a supporting frame, a driving module provided on the supporting frame, and a fan blade set covering the driving module and being driven by the driving module to rotate. The supporting frame is provided with a main body for the driving module and the fan blade set to be installed, as well as a plurality of supporting posts respectively connected to the main body and fixed on the circuit board, and the heat-dissipating fan is not provided with a barrier wall around the fan blade set.

In this case, the bottom case and the top cover are fitted together to delimit an accommodating space. The circuit board is mounted on the bottom case and located within the accommodating space. The circuit board is provided thereon with a plurality of electronic components and a plurality of heat-dissipating elements, each heat-dissipating element being provided correspondingly to one of the electronic components and allowed to conduct heat, respectively. Each of the heat-dissipating elements is provided with a mounting hole. The heat-dissipating fan includes a supporting frame, a driving module provided on the supporting frame, and a fan blade set covering the driving module and being driven by the driving module to rotate. Moreover, the heat-dissipating fan is not provided with a barrier wall around the fan blade set.

Abstract: 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.

Abstract: 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.

Abstract: 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.
