Abstract
A system for cooling a heat producing device is provided. The system can include an air mover (110) wherein at least a portion of the discharge airflow (115) is directed radially outward. The system can also include a thermal conduit (120) and a thermal member (130). The thermal member can have a first surface (135), a second surface (140) and at least one integrally formed heat exchange surface (150). At least a portion of the heat exchange surface (150) can be at least partially disposed in the air mover discharge airflow (115). At least a portion of the first surface (135) can be disposed proximate the thermal conduit (120). At least a portion of the second surface (140) can be disposed proximate the air mover (110).
Claims20
A heat exchange system comprising:
- an air mover wherein at least a portion of the air mover discharge airflow is directed radially outward;
- a thermal conduit;
- a thermal member having a first surface, a second surface and at least one integrally formed heat exchange surface integrally formed as a single unitary body with the first surface and the second surface;
- wherein at least a portion of the heat exchange surface is at least partially disposed in the air mover discharge airflow;
- wherein at least a portion of the first surface is disposed proximate the thermal conduit;
- and
- wherein at least a portion of the second surface is disposed proximate the air mover.
A method for cooling a heat producing device (910), comprising:
- conveying heat from the heat producing device via a thermal conduit having a first end and a second end;
- transferring at least a portion of the conveyed heat from the thermal conduit to a thermal member comprising a metallic member having a first surface, a second surface, at least one exterior edge, and at least one integral heat exchange surface integrally formed as part of a single unitary body with the first surface and the second surface;
- wherein at least a portion of the first surface is disposed proximate the thermal conduit;
- and
- directing at least a portion of an air mover radial discharge airflow across at least a portion of the heat exchange surface;
- wherein at least a portion of the heat exchange surface is disposed in the air mover radial discharge airflow;
- and
- wherein the heat exchange surface comprises a plurality of parallel fins folded about a transverse axis of the thermal member, the fins having minor dimension edges and major dimension faces, the faces extending in a single plane perpendicular to air mover discharge airflow;
- and
- wherein the folded parallel fins form an arc of at least 60° as measured between a longitudinal axis of the thermal member and a longitudinal axis of each of the plurality of folded parallel fins.
A system comprising:
- an air mover adapted to discharge at least a portion of the discharge airflow in a radial outward direction;
- a thermal conduit;
- a planar thermal member having a first surface, a second surface and at least one integral heat exchange surface integrally formed as part of a single unitary body with the first surface and the second surface;
- wherein at least a portion of the at least one integral heat exchange surface is at least partially disposed in the air mover discharge airflow;
- wherein at least a portion of the thermal member forms at least a portion of a housing about the air mover;
- and
- wherein at least a portion of the first surface is disposed proximate the thermal conduit;
- wherein the heat exchange surface comprises a plurality of parallel fins folded at an angle of at least 30° measured with respect to an axis perpendicular to a plane of the thermal member.
