Embodiment Construction

[0036] Please also refer to Figure 1 to Figure 4 , the fan 1 of the present invention can be an axial fan, including an impeller 11 , a motor 12 , a flow guide structure 13 and a guide ring 14 .

[0037] The impeller 11 has a hub 111 and a plurality of fan blades 112 disposed on the outer ring surface of the hub 11 , and the motor 12 is connected with the impeller 11 to drive the impeller 11 to rotate. Furthermore, the upper surface of the hub 111 has a plurality of balance holes 113, so that when the impeller 11 of the fan 1 runs unbalanced, appropriate balance materials can be filled in the above-mentioned balance holes 113 according to the shaking state of the impeller 11, so that The impeller 11 of the fan 1 can rotate in a balanced manner without shaking.

[0038] Again, the hub 111 center of the fan 1 has an air inlet groove 114, the inner wall surface of this inlet groove 114 is hollowed out, and communicates with the space where the motor 12 and the second circuit de...

Abstract

The invention discloses a fan and a guide structure thereof. The fan comprises a guide structure, an impeller and a motor, wherein the external diameter of the guide structure gradually expands to the bottom of the guide structure from the top of the guide structure. When the impeller rotates, airflow flows in from an air intake, flows along the outer ring surface of the guide structure and flows out from an air outlet, and the direction from which the airflow flows out from the air outlet is different from the direction from which the airflow flows in from the air intake. In addition, the guide structure consists of a plurality of heat dissipation fins.

Description

technical field [0001] The invention relates to a fan, in particular to a fan capable of changing the direction of air flow and improving the heat dissipation effect and its flow guiding structure. Background technique [0002] With the continuous improvement of the performance of electronic devices, cooling devices or cooling systems have become one of the indispensable equipment in current electronic devices, because if the heat energy generated by electronic devices is not dissipated properly, the performance will deteriorate at least, and the serious It may cause burning of the electronic device. Heat dissipation devices are even more important for microelectronic components (such as integrated circuits, ICs), because with the increase in integration and the advancement of packaging technology, the area of ​​integrated circuits is continuously shrinking, and the heat energy accumulated per unit area It will also be relatively higher, so heat dissipation devices with hig...
