Abstract

A temperature management apparatus, including a heat sink, including a base; a plurality of fins extending from the base in a first direction, the plurality of fins forming a first interface having a first angle with respect to a plane that is perpendicular to the first direction; and a fan including a second interface, the fan thermally coupled to the heat sink such that the second interface has a second angle with respect to the plane, the second angle the same as the first angle.

Claims (25)

1 . A temperature management apparatus, including:

a heat sink, including:

a base;

a plurality of fins extending from the base in a first direction, the plurality of fins forming a first interface having a first angle with respect to a plane that is perpendicular to the first direction;

a fan including a second interface, the fan thermally coupled to the heat sink such that the second interface has a second angle with respect to the plane, the second angle being the same as the first angle, and

wherein the plurality of fins are provided and exposed to an outer ambient environment between the base and the fan when the fan is aligned with the heat sink.

2 . The temperature management apparatus of claim 1 , wherein the fan is thermally coupled to the heat sink such that the first interface of the heat sink is proximate to the second interface of the fan.

3 . The temperature management apparatus of claim 2 , wherein the fan is thermally coupled to the heat sink such that the first interface of the heat sink is aligned with the second interface of the fan.

4 . The temperature management apparatus of claim 1 , wherein the heat sink includes a first side and a second side positioned opposite to the first side, wherein a first length of a first fin of the plurality of fins at the first side of the heat sink is less than a second length of a second fin of the plurality of fins at the second side of the heat sink.

5 . The temperature management apparatus of claim 4 , wherein a length of the remaining fins between the first fin and the second fin increase from the first side of the heat sink to the second side of the heat sink.

6 . The temperature management apparatus of claim 4 , wherein the fan includes a first end and a second end positioned opposite to the first end, wherein the fan is thermally coupled to the heat sink such that the first end of the fan is positioned proximate to the first side of the heat sink and the second end of the fan is positioned proximate to the second side of the heat sink, wherein a first velocity of air output by the fan at the second interface at the first end of the fan is less than a second velocity of air output by the fan at the second interface at the second end of the fan.

7 . The temperature management apparatus of claim 4 , further including a first and a second heat pipe in thermal communication with the heat sink, wherein the first heat pipe has a first length between the first side and the second side of the heat sink and the second heat pipe has a second length between the first side and the second side of the heat sink, wherein the first length is greater than the second length.

8 . An information handling system, comprising:

a temperature management apparatus, including:

a heat sink, including:

a base;

wherein the plurality of fins are provided and exposed to an outer ambient environment between the base and the fan when the fan is aligned with the heat sink.

9 . The information handling system of claim 8 , wherein the fan is thermally coupled to the heat sink such that the first interface of the heat sink is proximate to the second interface of the fan.

10 . The information handling system of claim 9 , wherein the fan is thermally coupled to the heat sink such that the first interface of the heat sink is aligned with the second interface of the fan.

11 . The information handling system of claim 8 , wherein the heat sink includes a first side and a second side positioned opposite to the first side, wherein a first length of a first fin of the plurality of fins at the first side of the heat sink is less than a second length of a second fin of the plurality of fins at the second side of the heat sink.

12 . The information handling system of claim 11 , wherein a length of the remaining fins between the first fin and the second fin increase from the first side of the heat sink to the second side of the heat sink.

13 . The information handling system of claim 12 , wherein the fan includes a first end and a second end positioned opposite to the first end, wherein the fan is thermally coupled to the heat sink such that the first end of the fan is positioned proximate to the first side of the heat sink and the second end of the fan is positioned proximate to the second side of the heat sink, wherein a first velocity of air output by the fan at the second interface at the first end of the fan is less than a second velocity of air output by the fan at the second interface at the second end of the fan.

14 . The information handling system of claim 11 , further including a first and a second heat pipe in thermal communication with the heat sink, wherein the first heat pipe has a first length between the first side and the second side of the heat sink and the second heat pipe has a second length between the first side and the second side of the heat sink, wherein the first length is greater than the second length.
