Abstract
A pulsating vapor chamber has an inner board, a first outer board, a second outer board, an asymmetric loop, and a working fluid. The inner board has a first surface and a second surface. The first and second outer boards are mounted on the first surface and the second surface of the inner board respectively. The asymmetric loop is located between the first and second outer boards and has multiple channels communicating with each other in sequence. A part of the channels are formed between the first outer board and the inner board, and the remaining channels are formed between the second outer board and the inner board. With the asymmetric loop, even if the vapor chamber is disposed horizontally, pressure may be changed by different amount in the channels so that the working fluid is still able to oscillate or circulate.
Claims15
A pulsating vapor chamber comprising:
- an inner board having
- a first surface, and
- a second surface opposite the first surface;
- a first outer board mounted on the first surface of the inner board;
- a second outer board mounted on the second surface of the inner board;
- a path formed between the first outer board and the second outer board, the path comprising a first end and a second end, the path extending between the first end and the second end;
- a communicating channel formed between the first outer board and the second outer board, the communicating channel comprising a third end and a fourth end, the communicating channel extending between the third end and the fourth end;
- a first hole formed through the first surface and the second surface of the inner board, the first hole communicating with the first end of the path;
- a second hole formed through the first surface and the second surface of the inner board, the second hole communicating with the second end of the path;
- and
- a working fluid in the path,
- wherein the third end of the communicating channel communicates with the first end of the path, and the fourth end of the communicating channel communicates with the second end of the path.
