Heat transfer device
View Patent ↗A refrigeration and/or heat transfer device includes a heating section and cooling section, a release member, and a one-way check valve affixed together in a continuous loop so working fluid may flow in one direction therein. The heating section absorbs heat and transfers such heat to the working fluid, thereby heating, expanding and increasing pressure upon the working fluid therein. The pressurized working fluid is released in a regulated manner from the heating section to the cooling section, thereby carrying the heat away. The released working fluid cools and transfers its heat to the surroundings within the cooling section. As released working fluid enters the cooling section, such fluid displaces already cooled working fluid, pushing such fluid through the one-way check valve back into the heating section to absorb heat. The working fluid may undergo a phase change or remain in a single phase throughout to enhance heat transfer.
1. A heat transfer device comprising:
a heating section having an inlet and outlet, wherein a working fluid absorbs heat from a heat source and is pressurized in said heating section without an electro-mechanical compressor;
a cooling section having an inlet and outlet;
a one-way check valve in fluid communication with said cooling section inlet and said heating section outlet to restrict the flow of said working fluid through said device to a single direction;
a vaporization expansion evaporation section wherein the pressurized, heated working fluid is allowed to expand without altering the chemical composition of said working fluid, thus absorbing ambient heat from a space surrounding said vaporization expansion evaporation section; and
wherein said working fluid is pressurized and flows within said device without requiring gravity or an electro-mechanical pump without altering said chemical composition of said working fluid.
2. The heat transfer device of claim 1 , wherein said working fluid in said cooling section transfers heat into an area adjacent a portion of said cooling section.
3. The heat transfer device of claim 1 , wherein said working fluid in said cooling section absorbs heat from an area adjacent a portion of said cooling section.
4. The heat transfer device of claim 1 , wherein said heating section comprises a segment of uninsulated conduit.
5. The heat transfer device of claim 4 , wherein said conduit comprises capillary tubing.
6. The heat transfer device of claim 1 , wherein said heating section comprises a vessel.
7. The heat transfer device of claim 1 , wherein said heating section comprises a heat exchange device in thermal contact with said heat source.
8. The heat transfer device of claim 1 , wherein said cooling section comprises a segment of uninsulated conduit.
9. The heat transfer device of claim 8 , wherein said conduit comprises capillary tubing.
10. The heat transfer device of claim 1 , wherein said cooling section comprises a vessel.
11. The heat transfer device of claim 1 , wherein said cooling section comprises a heat exchange device in thermal contact with an area adjacent said cooling section.
12. The heat transfer device of claim 1 , wherein said working fluid vaporizes after release from said heating section into said cooling section and condenses in said cooling section.
13. The heat transfer device of claim 1 , wherein said working fluid within said heating and cooling sections comprises a gas.
14. The heat transfer device of claim 1 , wherein said working fluid within said heating and cooling sections comprises a liquid.
15. The heat transfer device of claim 1 , wherein said heat source is selected from the group consisting of solar radiation, waste heat, body heat, geothermal heat, and ambient heat.
16. The heat transfer device of claim 1 , further comprising a condensed moisture collector to collect moisture forming on the outside of said device.
17. The heat transfer device of claim 16 , further comprising a purification mechanism for said condensed moisture collected from said device.
18. The heat transfer device of claim 1 , further comprising a release member in fluid communication with said heating section outlet and said cooling section inlet to regulate the release of heated working fluid therefrom.
