Abstract
Abstract In a circuit board installation in which circuit boards 24 are slidably mounted in opposed guide rails 22 of a rack 21 in a cabinet 20, an efficient and relatively inexpensive flat cooling module 1 is slidably mounted in opposed guide rails between two circuit boards. The cooling module 1 comprises a pair of flat side walls 2 spaced apart and sealed together around their edges to form a sealed chamber 6, an inlet port (not shown) connected to a source of pressurised cooling fluid and, in each of the side walls, mutually spaced orifices 12, in which nipples 14 may be fitted, through which pressurised cooling fluid is directed towards components 25 of the adjacent circuit boards 24.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
A circuit board installation comprising a cabinet or other enclosure including at least one rack accommodating circuit boards, wherein at least one substantially flat cooling module is slidably mounted in opposed guide rails of the rack adjacent a circuit board or circuit boards, which cooling module comprises a pair of substantially flat side walls spaced apart and sealed together around their peripheral edges to form a sealed chamber, at least one inlet port connected or adapted to be connected to a source of pressurised cooling fluid and, in one or each of the side walls, a plurality of orifices through which pressurised cooling fluid is directed towards components of an adjacent circuit board of the installation.
Claim 2
Dependent Claim
116 words
A circuit board installation comprising a cabinet or other enclosure including at least one rack accommodating circuit boards, wherein at least one substantially flat cooling module is slidably mounted in opposed guide rails of the rack adjacent a circuit board or circuit boards, which cooling module comprises a pair of substantially flat side walls spaced apart and sealed together around their peripheral edges to form a sealed chamber, at least one inlet port connected or adapted to be connected to a source of pressurised cooling fluid and, in one or each of the side walls, a plurality of orifices through which pressurised cooling fluid is directed towards components of an adjacent circuit board of the installation.
Claim 3
Dependent Claim
43 words
A circuit board installation as claimed in Claim 1, wherein the positions of at least some of the plurality of orifices in one or each side wall of the cooling module substantially correspond to the positions of components on an adjacent circuit board.
Claim 4
Dependent Claim
49 words
A circuit board installation as claimed in Claim 1 or 2, wherein, in each of at least some of the orifices in one or each side wall of the cooling module, a nipple is inserted for directing a jet or spray of pressurised cooling fluid in a particular direction.
Claim 5
Dependent Claim
29 words
A circuit board installation as claimed in any one of the preceding Claims, wherein the or each inlet port is located at the rear edge of the cooling module.
Claim 6
Dependent Claim
25 words
A circuit board installation as claimed in any one of the preceding Claims, wherein a self-sealing connector is secured in the or each inlet port.
Claim 7
Dependent Claim
29 words
A circuit board installation as claimed in any one of the preceding Claims, wherein the source of pressurised cooling fluid is housed externally of the cabinet or other enclosure.
Claim 8
Dependent Claim
40 words
A circuit board installation as claimed in any one of the preceding Claims, wherein the cooling fluid is compressed air or any other gas that will not have any deleterious effect on the components and materials of the circuit boards.
Claim 9
Dependent Claim
41 words
A circuit board installation as claimed in any one of the preceding Claims, wherein the chamber of the cooling module is sub-divided by internal barrier walls into a plurality of inter-connecting passages through which pressurised cooling fluid is caused to flow.
Claim 10
Dependent Claim
50 words
A circuit board installation as claimed in Claim 8, wherein, in the region of each of at least some of the orifices in one or each side wall, the cross-sectional area of the associated passage reduces gradually so that cooling fluid is directed from the orifice at a substantial pressure.
Claim 11
Dependent Claim
91 words
For use in a circuit board installation as claimed in any one of the preceding Claims, a substantially flat cooling module comprising a pair of substantially flat side walls spaced apart and sealed together around their peripheral edges to form a sealed chamber, at least one inlet port in the cooling module adapted to be connected to a source of pressurised cooling fluid and, in one or each of the side walls, a plurality of orifices through which pressurised cooling fluid can be directed towards components of an adjacent circuit board.
