Heat sink vent

1. Equipment, comprising:

a speaker enclosure comprising a chamber, a loudspeaker, and a vent;

an electronic component; and

a heat sink device arranged to dissipate the heat generated by the electronic component and comprising both the vent and also a thermally conductive element that extends from an end of the vent and that is thermally coupled with the electronic component, the vent comprising fins projecting from an inside surface of the vent and extending parallel to a longitudinal axis of the vent, the equipment being characterized in that it comprises a cable passage formed on or in a fin or between two adjacent fins, the cable passage extending along the length of said fin(s).

2. The equipment according to claim 1 , wherein the thermally conductive element comprises a plate lying in a plane perpendicular to the longitudinal axis of the vent, and wherein the vent flares at said end and opens out in said plate.

3. The equipment according to claim 2 , wherein the electronic component is mounted on a circuit card that lies between the plate and a face of the chamber, extending parallel to said plate and to said face.

4. The equipment according to claim 1 , wherein when seen in section on a plane perpendicular to its longitudinal axis, the vent presents a shape that is oblong.

5. The equipment according to claim 1 , wherein two adjacent fins are spaced apart by a distance e such that:

e> 2* h

where his a height of said fins.

6. The equipment according to claim 1 , wherein each fin is of a height that decreases on approaching the ends of the vent.

7. The equipment according to claim 1 , wherein the cable passage comprises a groove formed in a surface of a fin, which surface is remote from the inside surface of the vent from which said fin projects.

8. The equipment according to claim 7 , wherein the cable is inserted in the groove along the entire length of the vent, the groove holding the cable by pinching.

9. The equipment according to claim 1 , including a plurality of vents having respective longitudinal axes that are parallel.

10. The equipment according to claim 9 , wherein the plurality of vents includes at least two vents, each having a wall in contact with or coinciding with a wall of the other vent.

11. The equipment according to claim 1 , wherein the thermally conductive element comprises a plate forming an entire face of the chamber, or a portion thereof.

12. The equipment according to claim 1 , wherein the thermal coupling between the thermally conductive element and the electronic component is provided by thermal connection means positioned between the thermally conductive element and the electronic component.

13. The equipment according to claim 1 , he equipment being a set-top.
