Abstract
A first portion of each of a plurality of Qu-type heat pipes is disposed in a hot gas path, and a second portion of each of the plurality of Qu-type heat pipes disposed away from the hot gas path. Also, the first portion of each of the plurality of Qu-type heat pipes extracts heat from the hot gas path and wherein the second portion of each of the plurality of Qu-type heat pipes creates a vapor that exits each second portion of the plurality of Qu-type heat pipes and away from the hot gas path.
Claims14
An apparatus for delivering heat to an Organic Rankine Cycle, comprising:
- a plurality of Qu-type heat pipes including a first portion disposed in a hot gas path of a heat source, the plurality of Qu-type heat pipes configured to extract heat from the hot gas path;
- an evaporator disposed away from the heat source and including a plurality of Qu-type heat pipes, the evaporator being part of an Organic Rankine Cycle system;
- and
- a connector Qu-type heat pipe that connects the plurality of Qu-type heat pipes at the heat source with the second plurality of Qu-type heat pipes at the evaporator of the Organic Rankine Cycle system, wherein the connector Qu-type heat pipe transfers the extracted heat from the heat source to the evaporator of the Organic Rankine cycle system.
A heat pipe evaporator, comprising:
- a Qu-type heat pipe;
- a first portion of the Qu-type heat pipe disposed in a hot gas path;
- and
- a second portion of a Qu-type heat pipe disposed away from the hot gas path, the second portion of the Qu-type heat pipe including a plurality of fins connected with the second portion of the Qu-type heat pipe;
- and
- a cover having holes formed therein, each hole including an extension region;
- wherein the Qu-type heat pipe extracts heat from the hot gas path and creates a vapor at the second portion of the Qu-type heat pipe away from the hot gas path;
- wherein an outer portion of each fin is disposed next to the cover having corresponding holes wherein each hole receives a portion of each corresponding outer portion of each fin, wherein the extension region of each corresponding hole is not occupied by the corresponding fin through which a working fluid passes and becomes the vapor as it is heated by the second portion of the Qu-type heat pipe.
Apparatus for extracting heat, comprising
- a heat source having a plurality of Qu-type heat pipes arranged in a hot gas path of a waste heat source, wherein a first portion of each of the plurality of Qu-type heat pipes extracts heat from the hot gas path;
- an evaporator disposed apart from the heat source, wherein the evaporator comprises a plurality of Qu-type heat pipes;
- and
- a connector Qu-type heat pipe that connects the plurality of Qu-type heat pipes at the heat source with the plurality of Qu-type heat pipes at the evaporator, wherein the connector Qu-type heat pipe transfers the extracted heat from the heat source to the evaporator for evaporation thereby.
