Abstract

Embodiments of the present disclosure generally relate to heat transferring apparatuses and methods. The apparatus and methods utilize the Joule-Thomson effect to remove heat from a heat source to facilitate cooling of the heat source. In one example, an apparatus receives heat from an object to be cooled. The received heat is used to pressurize a fluid. The pressurized fluid is depressurized through a venturi using vapor pressure as a driving force, thus cooling the fluid.

First claim

What is claimed is:

1. A heat transfer device, comprising:
a body;
a lid assembly positioned on the body and defining an internal volume of the body;
an internal container located within the body, an outer wall of the internal container spaced apart from an inner wall of the body, the internal container including a bowl having an internal volume therein, the internal volume of the bowl separated from the internal volume of the body by a sealing member positioned over an opening formed through a sidewall of the bowl, the opening including a venturi; and
a puncturing device positioned to rupture the sealing member.

2. The heat transfer device of claim 1 , further comprising a plurality of heat sinks extending between the bowl and the body.

3. The heat transfer device of claim 1 , further comprising a recirculation system, the recirculation system having a first end coupled to the body and a second end coupled to the lid assembly.

4. The heat transfer device of claim 3 , wherein the recirculation system includes a plurality of recirculation paths.

5. The heat transfer device of claim 1 , wherein the puncturing device includes a spring-loaded needle.

6. The heat transfer device of claim 5 , wherein the puncturing device includes a stop plate coupled to the spring-loaded needle, the stop plate configured to engage the bowl of the internal container.

7. The heat transfer device of claim 1 , wherein the sealing member seals the opening formed through a sidewall of the bowl.

8. The heat transfer device of claim 7 , wherein the opening is in fluid communication with a venturi.

9. The heat transfer device of claim 1 , wherein the puncturing device includes a plurality of puncturing devices radially spaced about the internal container.

10. The heat transfer device of claim 9 , wherein each of the plurality of puncturing devices is aligned with an opening formed through a sidewall of the bowl.

11. The heat transfer device of claim 10 , wherein the internal volume of the bowl is partitioned into wedge-shaped compartments.

12. The heat transfer device of claim 1 , wherein the internal container is positioned concentrically with respect to the body.

13. A heat transfer device, comprising:
a body;
a lid assembly positioned on the body and defining an internal volume of the body;
an internal container located within the body, the internal container including a bowl having an internal volume therein, the internal volume of the bowl separated from the internal volume of the body by a plurality of sealing members positioned over openings formed through a sidewall of the bowl, the openings each including a venturi; and
a plurality of puncturing devices radially disposed around the body and aligned with each opening to rupture respective sealing members.

14. The heat transfer device of claim 1 , further comprising a venturi in fluid communication with the opening formed in the bowl when the sealing member is in a ruptured state.

15. A method of cooling an object, comprising:
positioning a heat transfer device adjacent to the object, the heat transfer device including, a body, a lid disposed on the body, and an internal container located within the body, the internal container including a sidewall opening comprising a venturi;
transferring heat from the object to fluid housed in the heat transfer device, thereby increasing a temperature and a pressure of the fluid;
rupturing a sealing member formed over the sidewall opening of the internal container with a puncturing device to release the heated fluid and allowing the fluid to expand and cool.

16. The method of claim 15 , wherein the heated fluid is released through the venturi.

17. The method of claim 15 , wherein the puncturing device is a needle.

18. The method of claim 15 , wherein the released fluid is recirculated within the heat transfer device.

19. The method of claim 15 , wherein the internal container includes a bowl, and the opening is formed in the bowl.
