Abstract
A heat sink includes a main body and multiple circular pipes. The main body is in contact with at least one heat emitter. The circular pipes are disposed inside the main body. The circular pipes extend in a shape of helices and are configured to convey refrigerant. The circular pipes are arranged such that the central axes of the helices are adjacent. Each two of the circular pipes of which the central axes of the helices are adjacent to each other are intertwined with each other.
Claims21
A heat sink comprising:
- a main body in contact with at least one heat emitter;
- and
- a plurality of flow paths disposed inside the main body and extending in a shape of helices, the plurality of flow paths being configured to covey refrigerant, wherein
- the plurality of flow paths are arranged such that central axes of the helices are adjacent, and
- each two of the plurality of flow paths of which the central axes of the helices are adjacent to each other are intertwined with each other.
A method of manufacturing a heat sink, the method comprising:
- forming a plurality of flow paths for conveying refrigerant by fabricating a plurality of pipes winding in a shape of helices, the plurality of pipes being arranged such that central axes of the helices are adjacent, each two of the plurality of pipes of which the central axes of the helices are adjacent to each other being intertwined with each other;
- and
- inserting, in a first metal material through casting, the plurality of pipes fabricated in the forming.
(canceled)
A method of manufacturing a heat sink, the heat sink including a block and a plurality of flow paths, the plurality of flow paths being disposed inside the block and extending in a shape of helices, the plurality of flow paths being arranged such that central axes of the helices are adjacent, each two of the plurality of flow paths of which the central axes of the helices are adjacent to each other are intertwined with each other, the method comprising:
- fabricating a plurality of plate-like members each having a plate surface perpendicular to the central axes of the helices and provided with parts of the plurality of flow paths;
- and
- configuring a block comprising the plurality of flow paths by stacking the plurality of plate-like members on each other.
