Abstract

A body heating/cooling apparatus comprising an enclosure (10) for raising or lowering the temperature of a fluid (22) prior to circulating the fluid (22) through a vest (55). The enclosure (10) has a first chamber (13) where the fluid (22) returning from the vest (55) is picked up by a pump (25) and recirculated through a second chamber (16). The vest (55) has an integrally formed channel (67) that passes through the vest (55) in serpentine fashion. The enclosure (10) may also be equipped with a module for also providing helmet cooling for racing car applications.

Claims

1. A body heating/cooling apparatus, comprising:

a) an enclosure;

b) a first chamber disposed inside the enclosure and containing a fluid;

c) a pump disposed inside the first chamber and having an outlet for conveying the fluid;

d) a second chamber disposed inside the enclosure and containing a heat transfer medium;

e) a first tube extending from the outlet of the pump and capable of conveying the fluid from the pump through the second chamber such that heat transfer between the fluid and the heat transfer medium occurs while the fluid passes through the second chamber;

f) a vest having a having an inlet and an outlet and a cavity disposed therebetween, the inlet connected to the first tube such that fluid is capable of flowing from the inlet in the vest to the outlet in the vest through the cavity;

g) a return tube extending from the outlet of the vest to the first chamber such that the fluid returns to the first chamber after passing through the vest;

h) a third chamber having a heat transfer medium therein, the third chamber disposed inside the enclosure and having an inlet and an outlet;

i) a blower having an outlet capable of engaging with the inlet to the third chamber;

j) a fourth chamber disposed inside the enclosure adjacent to the third chamber and having a heat transfer medium disposed therein;

k) a filter disposed between the third chamber and the fourth chamber;

l) a fifth chamber disposed adjacent to the fourth chamber;

m) a pressure equalization tube extending from the fourth chamber to the fifth chamber;

n) at least one filter covering an opening between the fourth chamber and the fifth chamber;

o) a sixth chamber disposed adjacent to the fifth chamber and having an outlet with an opening extending to the outside of the enclosure; and

,

p) a dividing wall having a plurality of apertures and disposed between the fifth and sixth chamber.

2. The apparatus of claim 1, wherein the enclosure is formed of an insulating material.

3. The apparatus of claim 2, wherein the enclosure is coated.

4. The apparatus of claim 3, wherein the enclosure is coated with a plastic material.

5. The apparatus of claim 1, wherein the pump is electrically operated.

6. The apparatus of claim 5, wherein the pump is capable of being supplied operating power from an automobile battery.

7. The apparatus of claim 1, wherein the first tube has a section formed out of copper.

8. The apparatus of claim 1, wherein the cavity in the vest is formed into a channel.

9. The apparatus of claim 8, wherein the channel is formed out of a plurality of lengths of a continuous channel disposed in serpentine fashion throughout the vest, the plurality of lengths of channel being connected to one another by a short passageway disposed between the ends of the length of channel.

10. The apparatus of claim 9, wherein the channel is formed between two layers of heat sealed plastic material.

11. A body heating/cooling apparatus, comprising:

a) an enclosure;

b) a first chamber disposed inside the enclosure and containing a fluid;

c) a pump disposed inside the first chamber and having an outlet for conveying the fluid;

d) a second chamber disposed inside the enclosure and containing a heat transfer medium;

e) a first tube extending from the outlet of the pump and capable of conveying the fluid from the pump through the second chamber such that heat transfer between the fluid and the heat transfer medium occurs while the fluid passes through the second chamber;

f) a vest having an inlet, an outlet, and a cavity disposed therebetween, the cavity created by a plurality of lengths of a continuous integrally formed channel disposed in serpentine fashion throughout the vest, the plurality of lengths of channel being connected to one another by short passageways disposed between the ends of the lengths of channel, the inlet connected to the first tube such that fluid is capable of flowing from the inlet of the vest to the outlet of the vest through the cavity; and

,

g) a return tube extending from the outlet of the vest to the first chamber such that the fluid returns to the first chamber after passing through the vest.

12. The apparatus of claim 11, wherein the enclosure is coated with a plastic material.

13. The apparatus of claim 11, wherein the channel is formed between two layers of heat-sealed plastic material.

14. A body heating/cooling apparatus, comprising:

a) an enclosure capable of containing a fluid;

b) a pump disposed inside the enclosure for conveying the fluid, the pump having an inlet and an outlet;

c) a first tube extending from the outlet of the pump;

d) a vest having an inlet, an outlet, and a cavity disposed therebetween, the cavity created by a plurality of lengths of a continuous integrally formed channel disposed in serpentine fashion throughout the vest, the plurality of lengths of channel being connected to one another by short passageways disposed between the ends of the lengths of channel, the inlet of the vest connected to the first tube such that fluid is capable of flowing from the inlet of the vest through the cavity and through the outlet of the vest; and

e) a return tube extending from the outlet of the vest to the inlet of the pump.

15. The apparatus of claim 14, wherein the enclosure is formed of an insulating material.

16. The apparatus of claim 15, wherein the enclosure is coated.

17. The apparatus of claim 16, wherein the enclosure is coated with a plastic material.

18. The apparatus of claim 14, wherein the pump is electrically operated.

19. The apparatus of claim 18, wherein the pump is capable of being supplied operating power from an automobile battery.

20. The apparatus of claim 14, wherein the first tube has a section formed out of copper.

21. The apparatus of claim 14, wherein the channel is formed between two layers of heat-sealed plastic material.
