Abstract
A combination includes an extruded heat sink and a fan secured to the heat sink. The heat sink includes a planar fin and an L-shaped fin. The planar fin and the L-shaped fin commonly define a channel and an entrance to the channel. The fan includes lead wires packed together. The lead wires are allowed to pass through the entrance one by one and to be received in the channel side by side after being turned 90 degrees.
Claims18
A combination comprising:
- a fan comprising a hub, a plurality of blades extending outwardly from the hub and lead wires packed side by side;
- and
- a heat sink comprising a core, a planar fin and an L-shaped fin integrally extruded with the core, a channel defined between the L-shaped fin and the planar fin for receiving the lead wires therein side by side along a circumferential periphery of the core, an entrance defined between the L-shaped fin and the planar fin and allowing the lead wires to enter the channel one by one, the entrance having a width which is larger than a diameter of each of the lead wires, but smaller than a sum of the diameters of the lead wires.
A combination comprising:
- an extruded heat sink comprising a planar fin and an L-shaped fin, the planar fin and the L-shaped fin commonly defining a channel and an entrance to the channel;
- and
- a fan secured to the heat sink and comprising lead wires, the lead wires being packed together and being allowed to pass through the entrance one by one to be finally received in the channel side by side after being turned 90 degrees.
A combination comprising:
- a heat sink having a round core and a plurality of fins extending radially outwardly and upwardly from a periphery of the core, the fins cooperatively define a recess above the core, one of the fins cooperating with an adjacent fin to define a channel and an entrance of the channel, the entrance being located outside the channel and having a width smaller than a width of the channel along a circumferential direction of the core;
- and
- a fan received in the recess, the fan having lead wires collected in the channel by passing through the entrance, a diameter of each of the lead wires being smaller than the width of the entrance, a sum of the diameters of the lead wires being larger than the width of the entrance but smaller than the width of the channel.
