Abstract

Abstract A controlled temperature garment using the counter flow heat exchanger principle to maintain an equal temperature distribution along the inner surface of the garment. Three layers of material are bonded together in such a manner as to provide flow channels along the garment. The garment comprises distribution, turning and collection chambers at each end of the channels; and a fluid discharge and collecting manifold to control the flow of the temperature controlling fluid.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 109 words
A controlled temperature garment including a temperature control flow distribution means and pumping means with a temperature controlling fluid, said garment comprising in combination: a. first arm section; b. second arm seCtion; c. first leg section; d. second leg section; e. body section each of said sections (a) through (e) having a plurality of vertically stacked channels, one on top of one another and side by side each other; f. said flow distribution means directing said temperature controlling fluid to each channel of said plurality of vertically stacked channels of said sections; and g. said fluid being independently controllable to each of said sections by said flow distribution means.
Claim 2
Dependent Claim 109 words
A controlled temperature garment including a temperature control flow distribution means and pumping means with a temperature controlling fluid, said garment comprising in combination: a. first arm section; b. second arm seCtion; c. first leg section; d. second leg section; e. body section each of said sections (a) through (e) having a plurality of vertically stacked channels, one on top of one another and side by side each other; f. said flow distribution means directing said temperature controlling fluid to each channel of said plurality of vertically stacked channels of said sections; and g. said fluid being independently controllable to each of said sections by said flow distribution means.
Claim 3
Dependent Claim 50 words
The device recited in claim 1 wherein each of said sections comprises a plurality of longitudinally extending channels formed by a plurality of intermittently spaced bonded flow dividing seams to form a fluid flow directing chamber to direct said fluid from said fluid distribution means to each of said sections.
Claim 4
Dependent Claim 107 words
The device recited in claim 2 wherein each of said chambers comprises: a. distribution chamber; b. an outer flow channel; c. turning chamber; d. inner flow channel; e. collecting chamber; f. discharge means; and g. said fluid being directed into said distribution chamber from distribution means wherein said distribution chamber opens onto a plurality of said outer flow channels in each of said sections wherein said fluid is directed from said outer flow channel into said turning chamber; wherein said fluid is further directed from said chamber through a plurality of said inner flow channels to said collecting chamber; wherein said fluid is discharged into discharge means.
Claim 5
Dependent Claim 193 words
The device recited in claim 3 wherein each of a plurality of said fluid conducting chambers for each of said sections is formed by three vertically stacked layers of material comprising: a. inner layer; b. middle layer; c. outer layer; d. said inner layer, middle layer, and outer layer being partially bonded together longitudinally to form a plurality of said chambers and a plurality intermittently spaced longitudinally extending seams wherein the unbonded portion of said middle layer and said outer layer between said seams define said outer flow channel; wherein the unbonded portion of said middle layer and said inner layer between said seams define said inner flow channel; wherein said middle layer material is shorter in the longitudinal direction at one end of said middle material than said outer layer and said inner layer; wherein said outer layer and inner layer are bonded together at said one end to form said turning chamber; wherein the three layers are unbonded together at the end opposite said bonded end to form a distribution chamber between said outer layer and said middle layer and a collecting chamber between said middle layer and said inner layer.
Claim 6
Dependent Claim 97 words
The device recited in claim 4 wherein said fluid enters at an extreme temperature and is guided from said distribution chamber to the plurality of said outer flow chambers in each section either giving up or gathering more heat depending upon the environment outside said first layer as it passes along the outer layer and is further directed into said inner flow channel by route of said turning chamber and depending upon the environment said fluid picks up or gives up heat to said inner layer of said material and is thereby discharged into a discharge means.
Claim 7
Dependent Claim 126 words
The device recited in claim 3 wherein said flow distribution means includes a supply means, distribution lines and pump means said distribution means comprising: a. fluid supply control means connected to said supply means; b. supply manifold operatively connected to supply control means to control the amount of fluid flow into said manifold; c. plurality of distribution tubes operatively connected to said supply manifold; d. plurality of distribution flow control means operatively connected to said distribution tubes to distribute the fluid to said distribution tubes; and e. said distribution tubes being operatively connected to each of said sections through said distribution lines theReby directing said fluid to each of said section being dependent upon the setting of said distribution control means and said supply control means.
Claim 8
Dependent Claim 26 words
The device recited in claim 6 wherein said distribution control means and supply control means are needle valves extending into said distribution means and said manifold.
Claim 9
Dependent Claim 64 words
The device recited in claim 5 wherein said discharge means includes a plurality of discharge lines and discharge tubing, said discharge means comprising: a. discharge manifold; b. plurality of discharge flow channels operatively connected to said manifold; c. said channels being operatively connected to said garment by a plurality of discharge lines; and d. said discharge manifold being operatively connected to said discharge tube.
Claim 10
Dependent Claim 17 words
The device recited in claim 8 wherein said discharge tube is connected as a closed loop system.
Claim 11
Dependent Claim 19 words
The device recited in claim 8 wherein said discharge tube discharges a temperature controlling fluid into the outside environment.
