Abstract
An apparatus for guiding air through electronic components is disclosed. The apparatus has an intake, a transition portion, and a focused egress. The transition portion is connected to the intake and defines a channel. The channel has a generally ‘u’ shaped cross-section and a first edge and a second edge configured to be positioned substantially opposing a surface. The focused egress is connected to the transition portion.
Claims23
An apparatus for guiding air to electronic components comprising:
- an intake having a vertically extending cross-section;
- a transition portion connected at a first end to the intake and defining a channel having a generally ‘u’ shaped cross-section, an open side of the channel having a first edge and a second edge configured to be positioned substantially opposing a surface, wherein at least the first edge is positioned a distance away from the surface forming a gap between the first edge and the surface, such that air flow is directed towards secondary electronic components;
- and
- a focused egress having a vertically extending cross-section and connected to a second, opposed end of the transition portion such that air flow is directed substantially horizontally towards a primary electronic component;
- wherein the gap extends from the intake to the focused egress along a length of the transition portion.
A system for guiding air to electronic components comprising:
- a housing having a base and a removable side;
- a circuit board attached to base of the housing;
- at least one fan attached to the housing;
- an intake having a vertically extending cross-section, and located adjacent to the at least one fan;
- an air guide attached to the removable side and having a generally ‘u ’shaped cross-section, an open side of the generally ‘u ’shaped air guide having a first edge and a second edge configured to be positioned substantially opposing a surface, wherein at least the first edge is positioned a distance away from the surface forming a secondary air flow between the first edge and the surface;
- an electronic chip attached to the circuit board;
- a heat sink attached to the electronic chip, wherein the air guide directs a primary air flow substantially horizontally toward the heat sink via a focused egress having a vertically extending cross-section;
- and
- secondary components positioned in the secondary air flow;
- wherein the secondary air flow extends from the at least one fan to the heat sink along a length of the air guide.
An apparatus for guiding air to electronic components comprising:
- an intake having a vertically extending cross-section configured to receive air flow from at least one fan;
- a transition portion attached at a first end to the intake;
- a focused egress having a vertically extending cross-section and attached to a second opposed end of the transition portion;
- and
- wherein the transition portion is configured to direct most of the air flow substantially horizontally from the intake to the focused egress, and the transition portion allows a secondary electronic portion of the air flow to escape from the main air flow and flow over a secondary electronic component, wherein the transition portion directs most air flow down a generally ‘u ’shaped channel, and allows a secondary portion of the air flow to escape between a first edge of the channel and a surface, the secondary air flow extending from the intake to the focused egress along a length of the transition portion.
