HEAT TRANSFER DEVICE AND METHOD OF MAKING SAME
A heat pipe is provided having an enclosed vapor chamber and a wick disposed within the vapor chamber. The wick comprises a plurality of lands having a thickness and a plurality of vents formed between the lands, wherein each vent includes a layer of wick having a thickness that is less than the thickness of the lands.
1 . A heat pipe comprising:
an enclosed vapor chamber; and
a wick disposed within the vapor chamber, the wick comprising a plurality of lands having a thickness and a plurality of vents formed between the lands, wherein each vent includes a layer of wick having a thickness that is less than the thickness of the lands.
2 . The heat pipe of claim 1 , wherein the thicknesses of each of the plurality of the lands are the same and the thickness of the wick in each of the vents is the same.
3 . The heat pipe of claim 1 , wherein the lands and the vents are localized to a portion of the wick.
4 . The heat pipe of claim 1 , wherein the lands are equally spaced apart by the vents.
5 . The heat pipe of claim 1 , wherein each of the vents is the same size and shape.
6 . The heat pipe of claim 1 , wherein at least some of the plurality of lands are shaped as ridges.
7 . The heat pipe of claim 1 , wherein the plurality of lands of the wick forms an orthogonal pattern.
8 . The heat pipe of claim 1 , wherein the wick in each of the vents is continuous between the lands.
9 . A heat pipe comprising:
a first wall and a second wall, the second wall spaced apart and opposite from the first wall, the first and second walls defining a vapor chamber therebetween; and
a wick associated with the second wall, the wick having a plurality of vents, wherein each vent comprises a layer of wick which is adjacent to the second wall and which has a thickness that is less than the thickness of the wick.
10 . The heat pipe of claim 9 , wherein the thickness of each vent is the same.
11 . The heat pipe of claim 9 , wherein the vents are localized to a portion of the wick.
12 . The heat pipe of claim 9 , wherein the vents are equally spaced apart.
13 . The heat pipe of claim 9 , wherein each of the vents is the same size and shape.
14 . The heat pipe of claim 9 , wherein the wick includes a plurality of ridges between the vents.
15 . The heat pipe of claim 9 , wherein the wick between the vents forms an orthogonal pattern.
16 . The heat pipe of claim 9 , wherein the wick in each of the vents is continuous between the lands.
17 . A heat pipe comprising:
a top wall and a bottom wall defining a vapor chamber therebetween; and
a wick associated with the bottom wall, the wick having a plurality of vents, wherein each vent has a layer of wick at a bottom thereof comprising a vent wick.
18 . The heat pipe of claim 17 , wherein the thickness of each vent wick is the same.
19 . The heat pipe of claim 17 , wherein the vents are localized to a portion of the wick.
20 . The heat pipe of claim 17 , wherein the vents are equally spaced apart.
21 . The heat pipe of claim 17 , wherein each of the vents is the same size and shape.
22 . The heat pipe of claim 17 , wherein the wick includes a plurality of ridges between the vents.
23 . The heat pipe of claim 17 , wherein the wick between the vents forms an orthogonal pattern.
24 . The heat pipe of claim 17 , wherein the vent wick is continuous between the lands.
