THERMAL MODULE AND ELECTRONIC ASSEMBLY INCORPORATING THE SAME

摘要

An electronic assembly includes a casing ( 10 ) of an electronic product, and a thermal module disposed in the casing. The casing has a sidewall ( 102 ) defining a plurality of slots ( 1011 ) therein. The thermal module includes a centrifugal blower ( 50 ), a fin assembly ( 40 ) and a plurality of sub-fins ( 701 ). The centrifugal blower defines an air outlet ( 502 ) therein. The fin assembly is disposed at the air outlet of the centrifugal blower and includes a plurality of fins ( 401 ) and has a plurality of air passages ( 402 ) formed between adjacent fins. The sub-fins are located between the fin assembly and the sidewall of the casing, and forming a plurality of air channels ( 702 ) therebetween. The air channels of the sub-fins communicate the air passages of the fin assembly with the slots of the sidewall of the casing.
