Abstract

A heat dissipation device for a heat-generating component includes at least one helically-shaped air tube having a length. The at least one air tube is thermally coupled to the heat-generating component to dissipate heat from the heat-generating component. Other embodiments of the heat dissipation device and methods for dissipating heat from a heat-generating component are further disclosed.

First claim

The invention claimed is:

1. A heat dissipation device for a heat-generating component, the heat dissipation device comprising:
a first sheet formed with spaced-apart grooves on a surface of the first sheet, the grooves being stretched diagonally from one side of the first sheet to the other and containing one or more curvatures along the length of the grooves, the grooves forming helically-shaped air channels, the first sheet integrally forming a first base plate secured to the heat-generating component, a first helically-shaped air tube, and a first wall positioned between the first base plate and the first helically-shaped air tube; and
a second sheet formed with spaced-apart grooves on a surface of the second sheet, the grooves being stretched diagonally from one side of the second sheet to the other and containing one or more curvatures along the length of the grooves, the grooves forming helically-shaped air channels, the second sheet integrally forming a second base plate secured to the heat-generating component, a second helically-shaped air tube, and a second wall positioned between the second base plate and the second helically-shaped air tube,
wherein the first wall and the second wall form a passage that defines a third helically-shaped air tube, and
wherein the first, second and third air tubes have a length with the helix shape being formed by the air channels that extend along the length of the air tubes, the first, second and third air tubes being thermally coupled to the heat-generating component by the first and second base plates to dissipate heat from the heat-generating component.

2. The heat dissipation device of claim 1 , wherein the third helically-shaped tube is disposed proximate to the heat-generating component.

3. The heat dissipation device of claim 1 , wherein each of the helically-shaped air tubes include an inlet provided on one end of the at least one air tube and an outlet provided on an opposite end of the air tube, wherein heated air produced by the heat-generating component flows from the inlet to the outlet.

4. The heat dissipation device of claim 3 , further comprising a fan configured to propel air from the inlets to the outlets of the helically-shaped air tubes.

5. The heat dissipation device of claim 1 , wherein each of the helically-shaped air tube includes an inner surface, wherein heated air produced by the heat-generating component flows along the inner surface.

6. The heat dissipation device of claim 1 , further comprising a housing configured to enclose the heat dissipation device.
