Abstract
A heat sink includes a plurality of fins arrayed in a first direction, and a heat pipe having a first extension extending in the first direction. A second direction extends perpendicularly to the first direction, a third direction extends perpendicularly to the first direction and the second direction, and when the heat pipe is viewed in the third direction, the heat pipe has a second extension spaced from the first extension in the second direction and extending in the first direction, and a joint which interconnects the first extension and the second extension and which is curved. The fins include a plurality of first fins arrayed along the first extension and the second extension and a second fin disposed around a position of the joint.
Claims11
An electronic device comprising:
- a cooling fan;
- a first air flow path formed around the cooling fan and includes a most downstream portion thereof;
- a second air flow path connected to, and spreading from a most downstream portion of the first air flow path;
- and
- a heat sink disposed in the second air flow path, the heat sink including:
- a first plurality of fins arrayed in a first direction;
- a second plurality of fins arrayed in the first direction
- a first heat pipe including a first extension and a second extension, each extending in the first direction, and a curved joint which interconnects the first extension and the second extension,
- wherein:
- a second direction extends perpendicularly to the first direction, and a third direction extends perpendicularly to the first direction and the second direction, and when the first heat pipe is viewed in the third direction, the second extension is spaced from the first extension in the second direction,
- the first plurality of fins are arrayed along the first extension and the second extension, and the second plurality of fins are arrayed along and disposed around the joint,
- the plurality of first fins are contacted with the first heat pipe and the plurality of second fins are not contacted with the first heat pipe,
- the second air flow path has a first flow area and a second flow area, adjacent to one another, the first flow area is located in the direction of the air flow from the most downstream portion of the first air flow path, the second flow area is located obliquely to the direction of the air flow from the most downstream portion of the first air flow path, a first air flow rate of an air flow generated in the first flow area is greater than a second air flow rate of an air flow generated in the second flow area,
- the heat sink is disposed in the second air flow path such that:
- (i) the joint is located in the second flow area, (ii) other portions of the first extension and the second extension are located in the first flow area, and (iii) the plurality of first fins are located in the first area and the plurality of second fins are located in the second area.
