Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
68 words
A mounting for effecting transfer of heat between an electronic device and a heat sink, comprising a substantially flat and thin layer consisting essentially of expanded graphite, and a relatively much thinner coating of bonding-and-filling material adhering to said layer and having qualities allowing it to fill interstitial spaces between abutted surfaces of said layer and a heat sink and to bond said layer to the heat sink.
Claim 2
Dependent Claim
68 words
A mounting for effecting transfer of heat between an electronic device and a heat sink, comprising a substantially flat and thin layer consisting essentially of expanded graphite, and a relatively much thinner coating of bonding-and-filling material adhering to said layer and having qualities allowing it to fill interstitial spaces between abutted surfaces of said layer and a heat sink and to bond said layer to the heat sink.
Claim 3
Dependent Claim
55 words
A mounting as set forth in claim 1 wherein said layer is a dense flexible and pliable material in which elongated expanded-graphite particles are partially compressed to a layer thickness of up to about thirty thousandths of an inch, and wherein said coating is of the order of about one ten-thousandth of an inch thick.
Claim 4
Dependent Claim
36 words
A mounting as set forth in claim 2 wherein said layer thickness is about five to ten thousandths of an inch, and wherein the material of said coating is bondable with surfaces of the heat sink.
Claim 5
Dependent Claim
41 words
A mounting as set forth in claim 3 wherein said material of said coating is meltable at relatively low temperature so as to flow onto and then solidify and bond with surfaces of the heat sink against which it is abutted.
Claim 6
Dependent Claim
23 words
A mounting as set forth in claim 4 wherein said material is paraffin solidified after application as said coating in a liquified state.
Claim 7
Dependent Claim
34 words
A mounting as set forth in claim 3 wherein said material of said coating is a plastic curable after being applied to said layer and being abutted with the surfaces of the heat sink.
Claim 8
Dependent Claim
29 words
A mounting as set forth in claim 3 wherein said material of said coating is an adhesive which is self-bonding with the surfaces of said heat sink under pressure.
Claim 9
Dependent Claim
47 words
A mounting as set forth in claim 3 further comprising a thin film of electrically-insulating material overlying said layer and bonded therewith by a second thin coating of bonding-and-filling material adhering both to said layer and to said film and filling interstitial spaces between abutted surfaces thereof.
Claim 10
Dependent Claim
50 words
A mounting as set forth in claim 8 further comprising a second flat and thin layer consisting essentially of expanded graphite, overlying said film, and a third thin coating of bonding-and-filling material adhering to both said second layer and to said film and filling interstitial spaces between abutted surfaces thereof.
Claim 11
Dependent Claim
68 words
A heat sink and mounting assembly for an electronic device, comprising a heat sink having surfaces disposed to confront and communicate heat from complementary surfaces of an electronic device, a thin layer consisting essentially of expanded graphite overlying said heat sink surfaces, and a relatively much thinner coating of bonding-and-filling material adhering to both said heat sink surfaces and to said layer and substantially filling interstitial spaces therebetween.
Claim 12
Dependent Claim
68 words
A heat sink and mounting assembly for an electronic device, comprising a heat sink having surfaces disposed to confront and communicate heat from complementary surfaces of an electronic device, a thin layer consisting essentially of expanded graphite overlying said heat sink surfaces, and a relatively much thinner coating of bonding-and-filling material adhering to both said heat sink surfaces and to said layer and substantially filling interstitial spaces therebetween.
Claim 13
Dependent Claim
49 words
A heat sink and mounting assembly as set forth in claim 10 wherein said layer comprises elongated expanded-graphite particles compressed from a much larger thickness to up to about thirty thousandths of an inch, and wherein said coating is of the order of about one ten-thousandth of an inch.
Claim 14
Dependent Claim
32 words
A heat sink and mounting assembly as set forth in claim 11 wherein said layer is about five to ten thousandths of an inch, and wherein said coating also overlies said layer.
Claim 15
Dependent Claim
34 words
A heat sink and mounting assembly as set forth in claim 11 wherein said material of said coating is cured after being applied to said layer and to said surfaces of said heat sink.
Claim 16
Dependent Claim
26 words
A heat sink and mounting assembly as set forth in claim 13 wherein said heat sink surfaces carry an activator material for curing said coating material.
