Abstract

An apparatus for enclosing an electronic component to a base comprising, an enclosure attached to a base and surrounding an electronic component. The enclosure divided into a first portion and a second portion along a first plane substantially parallel to the base. The second portion of the enclosure is attached to the base. The first portion of the enclosure is attached to the second portion of the enclosure. The enclosure including one or more extruding elements on an exterior surface of the enclosure. The one or more extruding elements on the exterior surface of the enclosure increases an exterior surface area of the enclosure facilitating dissipation of heat from the electronic component.

Claims (31)

1. An apparatus for enclosing an electronic component to a base, comprising:

an enclosure attached to a base and surrounding an electronic component;

the enclosure divided into a first portion and a second portion along a first plane substantially parallel to the base such that the first portion of the enclosure includes an exterior top surface of the enclosure, and the second portion includes a plurality of exterior side surfaces of the enclosure;

wherein the second portion of the enclosure is attached to the base;

wherein the first portion of the enclosure is attached to the second portion of the enclosure;

the enclosure including one or more extruding elements having a triangular cross-sectional shape along a length of each of at least two of the exterior side surfaces of the second portion of the enclosure; and

wherein the one or more extruding elements on the exterior side surfaces of the second portion of the enclosure increases an exterior surface area of the enclosure facilitating dissipation of heat from the electronic component.

2. The apparatus of claim 1 , wherein the exterior top surface of the first portion includes at least two extruding elements, wherein the at least two extruding elements are uniform in height.

3. The apparatus of claim 2 wherein the at least two extruding elements are symmetrically aligned with one and other.

4. The apparatus of claim 2 , wherein each of the at least two extruding elements have a triangular cross-sectional shape along the length thereof.

5. The apparatus of claim 2 , wherein each of the at least two extruding elements have a rectangular cross-sectional shape along the length thereof.

6. The apparatus of claim 1 , wherein each of the at least two of the exterior side surfaces of the second portion of the enclosure includes at least two extruding elements, wherein the at least two extruding elements are uniform in height.

7. The apparatus of claim 6 , wherein the at least two extruding elements are symmetrically aligned with one and other.

8. The apparatus of claim 6 , wherein each of the at least two extruding elements have a triangular cross-sectional shape along the length thereof.

9. The apparatus of claim 1 , further comprising:

a heat sink divided into a first portion and a second portion along a second plane, wherein the second plane is substantially parallel to the base; and

wherein the second portion of the heat sink is attached to the first portion of the enclosure.

10. The apparatus of claim 9 , wherein the second portion of the heat sink is attached to the exterior top surface of the first portion of the enclosure.

11. The apparatus of claim 10 , wherein a surface of the second portion of the heat sink attached to the exterior top surface of the first portion of the enclosure includes one or more elements.

12. The apparatus of claim 11 , wherein the one or more elements of the heat sink have a triangular cross-sectional shape along the length thereof.

13. The apparatus of claim 11 , wherein the one or more elements of the heat sink have a rectangular cross-sectional shape along the length thereof.

14. The apparatus of claim 11 , wherein a thermal adhesive detachably attaches the one or more elements of the heat sink to the exterior top surface of the first portion of the enclosure.

15. The apparatus of claim 11 , wherein at least two elements of the heat sink are symmetrical to one and other.

16. The apparatus of claim 11 , wherein the one or more elements of the heat sink are substantially aligned in parallel with one or more extruding elements of the exterior top surface of the first portion of the enclosure.

17. The apparatus of claim 4 , further comprising:

a heat sink divided into a first portion and a second portion along a second plane, wherein the second plane is substantially parallel to the base;

wherein the second portion of the heat sink is attached to the exterior top surface of the first portion of the enclosure;

wherein a surface of the second portion of the heat sink attached to the exterior top surface of the first portion of the enclosure includes one or more elements; and

wherein the one or more elements of the heat sink have a triangular cross-sectional shape along the length thereof.

18. The apparatus of claim 10 , wherein the exterior top surface of the first portion of the enclosure includes rows of extruding angular elements.

19. The apparatus of claim 18 , wherein a surface of the second portion of the heat sink includes rows of extruding angular elements coupled with the rows of extruding angular elements of the exterior top surface of the first portion of the enclosure.
