Abstract
A vapor chamber for spreading heat includes a housing having spaced-apart first and second plates, the first and second plates defining a hollow chamber. At least one opening is defined through the first and second plates, the opening being isolated from the hollow chamber. At least one insert is fitted into each opening. The insert may be a snap-in insert or may be stamped into the opening.
Claims20
A heat spreader comprising:
- a housing having first and second plates defining a hollow chamber therebetween,
- at least one opening defined through each of said first and second plates of said housing, said housing having a surface defining at least one passage connecting the openings of the first and second plates, wherein said passage is isolated from said chamber, and
- at least one insert adapted for receiving a fastener, the at least one insert being mounted directly into said at least one passage.
A heat spreader comprising:
- a housing including first and second plates that define a hollow vapor chamber therebetween;
- at least one depression formed in one of said plates which projects into said vapor chamber and is bonded to the other of said plates;
- said housing having an opening that penetrates through said depression and the other of said plates;
- and
- an insert adapted to receive a fastener, wherein said insert is mounted directly into said opening.

A heat sink comprising:
- a housing including first and second plates with an enclosed vapor chamber therebetween;
- at least one depression formed in one of said plates which projects into said vapor chamber and is bonded to the other of said plates;
- said depression having an opening defined therethrough, so as to define an isolated passage through said vapor chamber;
- an insert directly mounted into said opening and shaped to receive a fastener;
- and
- at least one fin directly attached to one of the plates of said housing.
3 more elements
A method for forming a heat spreader comprising the steps of:
- joining first and second plates to define a hollow vapor chamber therebetween;
- forming at least one depression in one of said plates, so that the depression projects into said vapor chamber and is bonded to the other of said plates;
- penetrating said depression and the other of said plates to form an passage through the vapor chamber;
- and
- mounting an insert directly into said opening, said insert being adapted to receive a fastener.
