Circumferential flow foam heat exchanger
| DWPI Title: Circumferential flow high temperature foam heat exchanger for transferring heat from one fluid to another fluid, has fluid distribution and collection slots and foam material that are configured to fluid distribution slots |
| Abstract: A heat exchanger is disclosed that includes a cold heat exchange zone including a foam material having an annular geometry and having fluid distribution and collection slots configured to distribute a cooling fluid circumferentially through the foam material. |
| Use: Heat exchanger, such as a high temperature foam heat exchanger, for transferring heat from one fluid to another fluid for a desired purpose. |
| Advantage: The heat exchanger minimizes the leakage and maximizes the amount of heat transfer surface area at a high thermal efficiency and low pressure drop. It is easily fabricated, reduces the risk of leakage operates at high temperature with low pressure, and improves heat transfer between hot/cold fluids. It confines the hottest fluid stream inside the cold stream and reduces the radiation losses to the outside environment. It may be easily constructed of all very high melting point materials. |
| Novelty: The heat exchanger has a foam material surrounding a hot fluid transfer passage, and an outer shell (102) surrounding the foam material. The foam material has fluid distribution slots (310) extending across the material from a manifold in an axial direction towards another manifold, and fluid collection slots extending from the latter manifold towards the former manifold. The fluid distribution and collection slots and the material are provided such that a fluid distributed to the fluid distribution slot enters the material to flow radially to be collected by the fluid collection slot, where the slots are tapered away from the manifolds. |
