Abstract

A heat dissipation apparatus having a base, a heat dissipater, and a plurality of fin arrays. The base has at least one horizontal portion disposed in the base and at least one vertical portion extending therefrom. At least one of the plurality of fin arrays coupled with the at least one horizontal portion of the heat dissipater and at least one of the plurality of fin arrays coupled with the at least one vertical portion of the heat dissipater.

First claim

1 . A heat dissipation apparatus comprising:
a base; two vertical portions, the two vertical portions connected to the base and dividing base into three sections, a first section, a second section and a third section; three vertical fin arrays directly connected to the base, the three vertical fin arrays comprising a first vertical fin array, a second vertical fin array, and a third vertical fin array, wherein the first vertical fin array is located in the first section, the second vertical fin array is located in the second section, and the third vertical fin array is located in the third section; and three horizontal fin arrays, each of the three horizontal fin arrays being directly connected to a corresponding one of the two vertical portions, wherein the first horizontal fin array is located in the first section and coupled to the first vertical fin array, wherein the second horizontal fin array is located in the second section and coupled to the second vertical fin array, and wherein the third horizontal fin array is located in the third section and coupled to the third vertical fin array.

2 . The heat dissipation apparatus of claim 1 , wherein the at least one vertical portion is two vertically extending portions.

3 . The heat dissipation apparatus of claim 2 , wherein the two vertically extending portions are evenly spaced along the base, thus forming a substantially twin “T” shape.

4 . The heat dissipation apparatus of claim 1 , wherein the at least one vertical portion is three vertically extending portions.

5 . The heat dissipation apparatus of claim 1 , wherein the heat dissipater is a vapor chamber.

6 . The heat dissipation apparatus of claim 1 , wherein the heat dissipater has a base plate coupled with one or more heat pipes, the base plate forming the bottom surface of the base.

7 . The heat dissipation apparatus of claim 6 , wherein the one or more heat pipes are a plurality of heat pipes, at least one heat pipe disposed in the at least one horizontal portion and at least one heat pipe disposed in the vertical portion.

8 . The heat dissipation apparatus of claim 6 , wherein the base plate is a vapor chamber.

9 . The heat dissipation apparatus of claim 1 , wherein the at least one fin array coupled with the at least one horizontal portion of the heat dissipater is substantially perpendicular to the horizontal portion and the at least one fin array coupled with the at least one vertical portion of the heat dissipater is substantially perpendicular to the vertical portion.

10 . The heat dissipation apparatus of claim 1 , wherein the at least one fin array coupled with the at least one horizontal portion of the heat dissipater outwardly extends relative to the horizontal portion and the at least one fin array coupled with the at least one vertical portion of the heat dissipater outwardly extends relative to the vertical portion.

11 . A heat dissipation apparatus comprising:
a base; at least two vertical portions, the at least two vertical portions connected to the base and dividing base into three sections, a first section, a second section and a third section, the at least two vertical portions evening spaced along the base forming a substantially twin “T” shape; three vertical fin arrays directly connected to the base, the three vertical fin arrays comprising a first vertical fin array, a second vertical fin array, and a third vertical fin array, wherein the first vertical fin array is located in the first section, the second vertical fin array is located in the second section, and the third vertical fin array is located in the third section; and three horizontal fin arrays, each of the three horizontal fin arrays being directly connected to a corresponding one of the at least two vertical portions, wherein the first horizontal fin array is located in the first section and coupled to the first vertical fin array, wherein the second horizontal fin array is located in the second section and coupled to the second vertical fin array, and wherein the third horizontal fin array is located in the third section and coupled to the third vertical fin array.

12 . The heat dissipation apparatus of claim 11 , wherein the at least one vertical portion is three vertically extending portions.

13 . The heat dissipation apparatus of claim 11 , wherein the heat dissipater is a vapor chamber.

14 . The heat dissipation apparatus of claim 11 , wherein the heat dissipater has a base plate coupled with one or more heat pipes, the base plate forming the bottom surface of the base.

15 . The heat dissipation apparatus of claim 14 , wherein the one or more heat pipes are a plurality of heat pipes, at least one heat pipe disposed in the at least one horizontal portion and at least one heat pipe disposed in the vertical portion.

16 . The heat dissipation apparatus of claim 14 , wherein the base plate is a vapor chamber.

17 . The heat dissipation apparatus of claim 11 , wherein the at least one fin array coupled with the at least one horizontal portion of the heat dissipater is substantially perpendicular to the horizontal portion and the at least one fin array coupled with the at least one vertical portion of the heat dissipater is substantially perpendicular to the vertical portion.

18 . The heat dissipation apparatus of claim 11 , wherein the at least one fin array coupled with the at least one horizontal portion of the heat dissipater outwardly extends relative to the horizontal portion and the at least one fin array coupled with the at least one vertical portion of the heat dissipater outwardly extends relative to the vertical portion.

19 . (canceled)

20 . The heat dissipation apparatus of claim 11 , wherein the at least one portion extending away from the upper surface is two portions extending away from the upper surface.
