| Category | Description |
|---|---|
| Theory | 2-Phase heat transfer |
| Application | 2-D heat distribution. Spreading heat by a single vapor chamber. Suitable for large heat flux and high power. |
| Shape | Complex shape in X and Y direction with pedestal. |
| Fixtures | Mounted with through-holes in vapor chamber. |
| Heat Source Contact | Direct contact. Mounting pressure up to 90 PSI. |
| Qmax | T=5mm > 400W; T=3mm > 200W; T=1mm > 60W |
| Cost | Vapor chamber has higher tooling cost, but high-volume production can reduce cost to about ~2× heat pipe. One vapor chamber may replace multiple heat pipes and fixture/base plates. |
| Category | Description |
|---|---|
| Theory | 2-Phase heat transfer |
| Application | 1-D heat distribution. Using one or more heat pipes to spread heat. Suitable for long distances between heat source and heat exchanger. |
| Shape | Round, flattened, or bent in any direction. |
| Fixtures | Additional fixture plates required to mount heat pipes. |
| Heat Source Contact | A base plate is required to contact the heat source unless flattened or machined. |
| Qmax | Ø5 > 20W; Ø6 > 40W; Ø8 > 60W |
| Cost | Lower cost for a single heat pipe, but additional tooling may be required for bending or flattening. |
