An electronic device includes a first housing with a first air inlet and outlet, a heat dissipation assembly, and a filter structure between the first housing and the heat dissipation assembly. The heat dissipation assembly defines a second air inlet and outlet. The first air inlet, the second air inlet, the second air outlet and the first air outlet communicate with each other. The heat dissipation assembly draws air across itself from the two air inlets, and expels the air from the two air outlets. The filter structure covers the second air inlet and defines a plurality of very small holes which function to filter dust out from the incoming air.

Electronic device

A heat dissipation device includes a conductive plate and a fastener. The fastener includes a fastening element and an elastic element coiled around the fastening element. The fastening element includes a pole portion and a head portion formed at one end of the pole portion. The conductive plate defines a supporting portion through the conductive plate. The supporting portion defines a hole, an upper groove and a lower groove communicating with one another. The upper groove and the lower groove are coaxial with each other. A flange protrudes from a circumference of the pole portion. The pole portion enters the upper groove. The flange abuts a bottom of the conductive plate and is received in the lower groove. The elastic element elastically abuts the top of the conductive plate.

Heat dissipation device with fastener

A heat dissipation device includes a heat pipe and a fin set. The fin set includes a plurality of fins. Each of the fins includes a body, a first flange vertically extending from a top side of the body, and a second flange vertically extending from a bottom side of the body. The first flange has a first edge abutting a front neighboring fin and a second edge spaced to the first edge to define a slit. The first flange forms an extending portion extending from the second edge to define a gap between the extending portion and the body of the front neighboring fin. Each of the extending portions is soldered to the body of the front neighboring fin by solder filled in the gap between the extending portion and the body of the front neighboring fin from the slit.

Heat dissipation device with fin set

An exemplary electronic device includes a container, a fan assembly and a duct received in the container. The fan assembly includes a centrifugal fan and a fin group thermally contacting an electronic component in the container. An air passage is defined between each adjacent fins of the fin group. An inner side of the fin group is mounted on an outlet of the centrifugal fan. A bottom surface of the fin group and an inner surface of the container cooperatively define a first channel therebetween. The duct includes an inlet and a first outlet. Airflow guided by the centrifugal fan flows through the duct and the first channel to cool a bottom end of the fin group, then is absorbed into the centrifugal fan from an inlet of the centrifugal fan, and then flow through the air passages of the fin group to cool a central portion the fin group.

An electronic device includes a casing, a fan, and a heat sink. The casing defines a plurality of through holes therein. The fan defines air outlet at one side thereof facing the through holes of the casing. The air outlet includes a first portion and a second portion. Air pressure in the first portion is larger than air pressure of the second portion. The heat sink includes a first fin set arranged on the first portion and a second fin set arranged on the second portion. A first passage is defined between each two neighboring first fins. A second passage is defined between each two neighboring second fins. A width of the second passage is less than that of the first passage.

Electronic device with heat dissipation module

An LED lamp includes a heat sink, a reflecting cup, a heat pipe and an LED. The heat sink includes fins cooperatively defining a receiving space therein. Each of the fins includes a plate-shaped main body and a flange extending rearward from a periphery side of the main body. The flanges are connected to each other to cooperatively form an annular supporting surface. The reflecting cup is received in the receiving space of the heat sink. The heat pipe includes an evaporating section located above the reflecting cup and a condensing section thermally connecting with the annular supporting surface of the heat sink. The LED is directly mounted on the evaporating section with a light emitting surface facing downwardly towards the reflecting cup.

LED lamp

An exemplary light fixture includes a holder, an envelope and a lamp body. The lamp body includes a heat dissipation portion, a light source and a shield. The heat dissipation portion has top and bottom ends connecting to the holder and the envelope, respectively. The light source is mounted on the bottom end of the heat dissipation portion and covered by the envelope. The heat dissipation portion includes a plurality of fins extending from the top end to the bottom end of the heat dissipation portion. A passage is defined between every two adjacent fins. The shield surrounds the fins and defines a plurality of windows therein, communicating with the passages.
