Description

Technical Field

[0001] The utility model relates to the field of fans, in particular to a heat dissipation device with a rectification mechanism and a fan structure thereof. Background Art

[0002] With the advancement of technology, the functions of 3C products such as computers are becoming more and more diverse, and the heat generated by the electronic components inside them is also more considerable. Therefore, most electronic components require cooling fans and cooling fins to help dissipate heat to ensure that the electronic components can operate normally.

[0003] However, the conventional fan mainly includes a hub and a plurality of blades disposed on the hub. The outer surface of each blade is smooth, so that each blade does not generate airflow specifically blowing toward the heat sink fins when rotating, and thus the functions of the heat sink fan and the heat sink fins do not have an additive effect. Therefore, how to make the heat sink fan generate airflow blowing toward the heat sink fins is the key point that the heat sink device industry is eager to improve.

[0004] In view of this, the applicant has devoted himself to the above-mentioned prior art and has made scientific efforts to solve the above-mentioned problems. This is the purpose of the applicant. Utility Model Content
