A heat sink clip () includes a spring member (), a moveable locking member () and an actuating member (). The spring member includes an elongated main body () and a first locking leg () connecting at one end of the main body. The locking member is coupled at the other end of the main body, including an engaging plate () and a second locking leg () extending from the engaging plate. The actuating member includes a handle () and an extension portion () formed at one end of the handle. The handle and the extension portion form an angle therebetween. The extension portion is operatively engageable with the engaging plate of the locking member.

Clip for heat sink

A fastening device for a heat sink includes a one-piece shaft. The shaft includes a head at one end thereof, an engaging section at an opposite end thereof, a connecting section between the head and the engaging section, and a tray extending above the engaging section. A spring surrounds the connecting section between the head and the tray of the shaft. A gasket engages with the connecting section of the shaft and is retained between the spring and the tray of the shaft. In this way the shaft, the spring and the gasket are assembled. The gasket extends a downward, annular sidewall for engaging in the heat sink, by which the fastening device can be stably fixed to the heat sink. A back plate extends a nut toward the shaft for engaging with the engaging section of the shaft.

Fastening device for heat sink

A heat sink clip for securing a heat sink to a heat generating electronic component includes a spring member including an elongated main body. A connecting portion is formed at one end of the main body and a first locking leg extends from the other end thereof. A second locking leg is coupled to the connecting portion of the spring member. An actuating member connects pivotally with the second locking leg. An assisting member, which is located between the actuating member and the connecting portion, includes a wedged main body. When the actuating member is rotated from a first orientation to a second orientation, the assisting member horizontally moves a distance thereby moving the actuating member to a raised level. The actuating member has teeth engaging with teeth formed on an inclined face of the wedged main body.

Heat sink clip

A heat sink includes first and second fin sets. The first fin set includes a plurality of fins each having a flange extending perpendicularly from an edge thereof and oriented in a same first direction. The flanges engage with each other in succession through locking parts formed thereon. The second fin set includes a plurality of fins each having a flange extending perpendicularly from an edge thereof and oriented in a same second direction toward the first direction. The flanges engage of the second fins with each other in succession through locking parts formed thereon. One of the flanges of an outmost one of the fins of the first fin set and one of the flanges of an outmost one of the fins of the second fin set are extended toward to and engaged with each other.

Heat sink

A heat-pipe type heat sink () includes a plurality of fins (), at least a heat pipe () extending through the fins, and soldering material () disposed between the heat pipe and the fins. Each of the fins defines therein a through hole () and a cutout () adjacent to the through hole. A sidewall of the through hole forms a collar () contacting with the heat pipe, whilst a sidewall of the cutout forms at least a fringe () connecting with the collar. The fringe guides the soldering material in molten state to flow from the cutout towards the collar to fill in a gap formed between the heat pipe and the fins to bond the heat pipe and the fins together after the molten soldering material is cooled.

Heat-pipe type heat sink

A retention module () for securing a heat sink () to a printed circuit board () includes a pair of carriage arms () separated by a space and a connecting wall () interconnecting opposite rear free ends of the carriage arms. Each of the carriage arms integrally forms a lock catch () thereon to clasp the heat sink. A pair of opposite positioning ears () extend upwardly from corners where the carriage arms are connected with the connecting wall. The retention module and the heat sink are preassembled together via the lock catches clasping the heat sink before the retention module is mounted on the printed circuit board.

Retention module for a heat sink

A heat dissipating apparatus () includes a base (), a plurality of stacked fins (), and at least a heat pipe (). The base absorbs heat from a heat-generating component. Each of the fins includes a main body (), and a plurality of projection members () extending from the main body. The projection members of a first fin connect the projection members of a second fin. The projection members form a first heat transfer path for transferring heat from the base to the fins. The heat pipe includes a heat-absorbing portion () thermally contacting with the base, and a heat-dissipating portion () contacting with the fins. The heat pipe forms a second heat transfer path for transferring the heat from the base toward the fins.

Heat dissipating apparatus

A heat dissipation device includes a heat sink with a plurality of fins, a fan mounted on a side of the heat sink with a space formed between the heat sink and the fan, and at least one airflow guiding board formed by one end of at least one of the fins. The airflow guiding board extends through the space to connect with the fan. The airflow guiding board can guide the airflow generated by the fan to the heat sink, so as to reduce the loss of the airflow from the edge of the heat sink, and enhance the effect of heat dissipation. Alternatively, the airflow guide board can also function to guide the airflow to cool other heat sinks.

Heat dissipation device

A grease cover () for protecting grease spread on a bottom surface of a heat sink () includes a base wall (), a plurality of sidewalls (), a protecting space () between the base wall and the sidewalls, a holding space in an upper portion of the protecting space, and two projections (). The protecting space is for accommodating the grease. The holding space is for receiving the heat sink therein. The projections extend from two opposite sidewalls of the grease cover. A top surface of each of the projections spaces a distance from the base wall, for supporting the bottom surface of the heat sink to enable the grease away from the base wall, when the heat sink is received in the holding space.

Grease cover for heat dissipating apparatus

A heat dissipation device () includes at least a heat pipe () and a plurality of metal fins () thermally connected to the heat pipe. Each of the metal fins defines therein an aperture (). An extension flange () extends outwardly from the metal fin and surrounds the aperture. The extension flange defines therein a plurality of slits (). The apertures and extension flanges of the metal fins are aligned together. The heat pipe is received in the aligned apertures and soldered by a thermal medium material to the metal fins via the aligned extension flanges. During the soldering process, rosin content contained in the thermal medium material can be discharged away via the slits formed in the extension flange.
