Abstract
A heat sink having a very high heat transfer capability may be made from a plurality of unit elements. Each unit element includes a series of inlet tubes having a range of diameters and a series of outlet tubes also having a range of diameters. At least one inlet tube having a minimum inlet tube diameter may be in flow communication with at least one outlet tube having a minimum outlet tube diameter.
Claims13
A unit element for a heat sink, comprising:
- a series of inlet tubes having a range of diameters, the range of diameters including a maximum inlet tube diameter and a minimum inlet tube diameter;
- a series of outlet tubes having a range of diameters, the range of outlet tube diameters including a maximum outlet tube diameter and a minimum outlet tube diameter;
- a plurality of flow branch points, each having an incoming flow and a plurality of outgoing flows and each formed by the intersection of two or more of the inlet or outlet tubes;
- at least one inlet tube having the minimum inlet tube diameter being in flow communication with at least one outlet tube having the minimum outlet tube diameter,
- wherein each of the intersections is defined by an incoming flow, a first outgoing flow perpendicular to the incoming flow, and a second outgoing flow orthogonal to the first outgoing flow.
2 more elements
A heat sink comprising:
- a plurality of tubes in fluid communication with one another through a plurality of respective intersections, each intersection formed by an incoming tube and a plurality of outgoing tubes, each of the tubes having a radius that is essentially governed by the following relationship:
- r03=r13+r23+r33+ . . . +rn3
- where r0 is the radius of the incoming tube, and rl, r2, . . . , rn are the radii of the outgoing tubes,
- wherein, for each of a plurality of intersections, a first outgoing tube is perpendicular to the incoming tube and a second outgoing tube is orthogonal to the first outgoing tube.
