Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
81 words
An apparatus for cooling an electronic device comprising: a vessel having upper and lower regions; inlet means for delivering a flow of cooling fluid to said upper region; means for positioning said device within said lower region and above the bottom of said vessel; divider means within said vessel disposed between said flow and said device; and overflow means transferring fluid from said upper to said lower region such that the overflow means prevents fluid from directly contacting the electronic device.
Claim 2
Independent Claim
81 words
An apparatus for cooling an electronic device comprising: a vessel having upper and lower regions; inlet means for delivering a flow of cooling fluid to said upper region; means for positioning said device within said lower region and above the bottom of said vessel; divider means within said vessel disposed between said flow and said device; and overflow means transferring fluid from said upper to said lower region such that the overflow means prevents fluid from directly contacting the electronic device.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 wherein said divider means is located between said upper and lower regions.
Claim 4
Dependent Claim
18 words
The apparatus of claim 2 wherein said divider means is shaped to capture a portion of said fluid.
Claim 5
Dependent Claim
12 words
The apparatus of claim 3 wherein said divider means is conically shaped.
Claim 6
Dependent Claim
27 words
The apparatus of claim 1 wherein said overflow means includes a plurality of first tubes extending through said divider means from said upper to said lower region.
Claim 7
Dependent Claim
19 words
The apparatus of claim 5 wherein said first tubes are located generally on the periphery of said divider means.
Claim 8
Dependent Claim
37 words
The apparatus of claim 1 further comprising: relief means for the transfer of evaporated fluid from said lower to said upper region; wherein said inlet means includes means for removing said evaporated fluid from said upper region.
Claim 9
Dependent Claim
27 words
The apparatus of claim 7 wherein said relief means includes a plurality of second tubes extending through said divider means from said lower to said upper region.
Claim 10
Dependent Claim
32 words
The apparatus of claim 7 wherein said inlet means comprises two concentrically positioned inner and outer tubes with the inner tube delivering said fluid and the outer tube removing said evaporated fluid.
Claim 11
Dependent Claim
28 words
The apparatus of claim 1 further comprising: a valve for controlling the rate at which said inlet means delivers said flow of cooling fluid to said upper region.
Claim 12
Dependent Claim
37 words
The apparatus of claim 9 further comprising: a valve for controlling the rate at which said inlet means delivers said flow of cooling fluid to said upper region, wherein said valve is positioned within said inner tube.
Claim 13
Independent Claim
137 words
An apparatus for cooling an electronic device comprising: a vessel having upper and lower regions; inlet means for delivering a flow of cooling fluid to said upper region and for removing evaporated fluid therefrom; means for positioning said device within said lower region and above the bottom of said vessel; divider means within said vessel located between said first and second regions and disposed between said flow means and said device; overflow means for transferring fluid from said upper to said lower region, wherein said overflow means includes a plurality of first tubes extending through said divider means from said upper to said lower region and oriented so that the flow of fluid passing therethrough is directed away from said device; and relief means for the transfer of evaporated fluid from said lower to said upper region.
Claim 14
Independent Claim
137 words
An apparatus for cooling an electronic device comprising: a vessel having upper and lower regions; inlet means for delivering a flow of cooling fluid to said upper region and for removing evaporated fluid therefrom; means for positioning said device within said lower region and above the bottom of said vessel; divider means within said vessel located between said first and second regions and disposed between said flow means and said device; overflow means for transferring fluid from said upper to said lower region, wherein said overflow means includes a plurality of first tubes extending through said divider means from said upper to said lower region and oriented so that the flow of fluid passing therethrough is directed away from said device; and relief means for the transfer of evaporated fluid from said lower to said upper region.
Claim 15
Dependent Claim
19 words
The apparatus of claim 12 wherein said divider means is conically shaped to capture a portion of said fluid.
Claim 16
Dependent Claim
42 words
The apparatus of claim 13 wherein said first tubes are located generally on the periphery of said divider means, and wherein said relief means includes a plurality of second tubes extending through said divider means from said lower to said upper region.
Claim 17
Dependent Claim
32 words
The apparatus of claim 14 wherein said inlet means comprises two concentrically positioned inner and outer tubes with the inner tube delivering said fluid and the outer tube removing said evaporated fluid.
Claim 18
Dependent Claim
28 words
The apparatus of claim 15 further comprising: a valve for controlling the rate at which said inlet means delivers said flow of cooling fluid to said upper region.
Claim 19
Dependent Claim
19 words
The apparatus of claim 1 further comprising: support means positioning said divider means between said upper and lower regions.
Claim 20
Dependent Claim
70 words
The apparatus of claim 17 wherein said divider means is shaped to capture a portion of said fluid and wherein said support means includes a wall surrounding said electronic device and extending from said bottom of said vessel into said upper region and being attached to the periphery of said divider means, wherein said wall is spaced inwardly from the side wall of said vessel thereby forming a channel therebetween.
Claim 21
Dependent Claim
36 words
The apparatus of claim 18 wherein said wall includes a plurality of spaced apart lower openings proximate said bottom of said vessel and a plurality of spaced apart upper openings proximate but below said divider means.
Claim 22
Independent Claim
72 words
A method for gradually cooling an electronic device comprising: providing a vessel with first, second and third regions; providing inlet means for delivering cooling fluid to said first region; positioning said device within said third region above the bottom of the vessel; providing divider means within said vessel between said inlet means and said device; and sequentially delivering cooling fluid to, and holding said fluid in, said first, second and third regions.
Claim 23
Independent Claim
72 words
A method for gradually cooling an electronic device comprising: providing a vessel with first, second and third regions; providing inlet means for delivering cooling fluid to said first region; positioning said device within said third region above the bottom of the vessel; providing divider means within said vessel between said inlet means and said device; and sequentially delivering cooling fluid to, and holding said fluid in, said first, second and third regions.
