Abstract
Embodiments of the invention provide systems and methods for heat transfer systems at temperatures in the range of 20 C to 800 C. The systems consist of heat pipes configured such that they fit inside conventional heat exchangers, and more effectively transfer or recover heat from hot fluids, and that operate without user intervention over long periods of time.
Claims12
A system, comprising:
- a first heat source;
- a heating vessel containing a saline solution having a first salinity;
- a first plurality of heat pipes, wherein a first portion of each heat pipe is in thermal communication with the first heat source and a second portion of each heat pipe is in thermal communication with the saline solution in the heating vessel;
- a forward osmosis vessel containing a semipermeable membrane;
- a draw solution vessel containing a draw solution having a second salinity, wherein the second salinity is higher than the first salinity;
- and
- a draw solution recovery system.
4 more elements
A Multi-Effect Distillation (MED) system, comprising:
- a condensation vessel, the condensation vessel comprising an inlet configured to allow steam to enter the condensation vessel;
- an evaporation vessel adjacent to the condensation vessel;
- a plurality of heat pipes, wherein each heat pipe comprises a first portion within the condensation vessel and a second portion within the evaporation vessel;
- and
- a plurality of spray nozzles configured to spray a saline solution into the evaporation vessel and onto the second portion of the heat pipes.
2 more elements
A system, comprising:
- a heat source;
- a pre-heating vessel containing a saline solution;
- a plurality of heat pipes, wherein a first portion of each heat pipe is in thermal communication with the heat source and a second portion of each heat pipe is in thermal communication with the saline solution in the pre-heating vessel;
- a high-pressure pump;
- and
- a reverse osmosis vessel containing a reverse osmosis membrane.
3 more elements
A vapor compression distillation system, comprising:
- a heat pipe, wherein a first portion of the heat pipe is located in a first portion of the vapor compression distillation system, and a second portion of the heat pipe is located in a second portion of the vapor compression distillation system;
- wherein the heat pipe is configured to transfer heat from the first portion of the vapor compression distillation system to the second portion of the vapor compression distillation system.
