Abstract
Abstract A cooling system for cooling electrical components in a personal computer is provided. The cooling system provides filtered air under a positive air pressure to such components in the computer, as the electrical power supply and microprocessor, as well as other components in the computer. The filtered air cools the components and prevents dust from collecting on the components. In a second embodiment, the cooling system includes a tower style case for supporting the personal computer. The case houses an air filter and induction fans, for providing copious cooling air flow through ducts in the computer. Air vents are placed in optimal areas in the computer, such as near the microprocessor and power supply, to provide increased air circulation for the components in these areas. A switch panel is additionally provided that enables energizing peripheral devices when desired.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
284 words
A cooling system in a personal computer, said personal computer including an electrical power supply and at least one microprocessor retained in a computer housing, said cooling system comprising: a cooling system housing having a top and a bottom, said cooling system housing supporting said computer housing on the top thereof; at least one air blower means located in said cooling system housing, said blower means inducing a positive air pressure within said computer housing; at least one air filter element in a serial arrangement with said blower means and located in said cooling system housing, said air filter element located upstream of said computer housing, such that said blower means delivers a stream of filtered air to said computer housing; means for directing said stream of filtered air from said at least one air blower means in said cooling system housing to said computer housing, said stream of filtered air directing means comprising an air outlet port formed through the top of said cooling system housing in fluid connection with an air inlet port disposed in the bottom of said computer housing; and means for dividing said stream of filtered air into at least two flow paths, including a first flow path and a second flow path, said dividing means comprising an air duct within said computer housing and in fluid connection with said air inlet port, said air duct having a first branch directing filtered air from said blower means, along said first flow path, to said electrical power supply and a second branch directing filtered air from said blower means, along said second flow path, to said at least one microprocessor and to other electrical components retained within said computer housing.
Claim 2
Dependent Claim
284 words
A cooling system in a personal computer, said personal computer including an electrical power supply and at least one microprocessor retained in a computer housing, said cooling system comprising: a cooling system housing having a top and a bottom, said cooling system housing supporting said computer housing on the top thereof; at least one air blower means located in said cooling system housing, said blower means inducing a positive air pressure within said computer housing; at least one air filter element in a serial arrangement with said blower means and located in said cooling system housing, said air filter element located upstream of said computer housing, such that said blower means delivers a stream of filtered air to said computer housing; means for directing said stream of filtered air from said at least one air blower means in said cooling system housing to said computer housing, said stream of filtered air directing means comprising an air outlet port formed through the top of said cooling system housing in fluid connection with an air inlet port disposed in the bottom of said computer housing; and means for dividing said stream of filtered air into at least two flow paths, including a first flow path and a second flow path, said dividing means comprising an air duct within said computer housing and in fluid connection with said air inlet port, said air duct having a first branch directing filtered air from said blower means, along said first flow path, to said electrical power supply and a second branch directing filtered air from said blower means, along said second flow path, to said at least one microprocessor and to other electrical components retained within said computer housing.
Claim 3
Dependent Claim
22 words
The cooling system of claim 1 wherein said at least one filter element has a surface area of approximately 1613 square centimeters.
Claim 4
Dependent Claim
20 words
The cooling system of claim 1 wherein said at least one filter element comprises a concertia or zig-zag type filter.
Claim 5
Dependent Claim
32 words
The cooling system of claim 1 further comprising a second air blower means within said first flow path for inducing an air flow past said electrical power supply within said computer housing.
Claim 6
Dependent Claim
48 words
The cooling system of claim 1 further comprising at least one air outlet vent formed through said computer housing, said at least one air outlet vent being located proximate said at least one microprocessor so as to induce a flow of air past said at least one microprocessor.
Claim 7
Dependent Claim
79 words
The cooling system of claim 5 wherein said at least one air outlet vent through said computer housing further comprises a flapper valve means for allowing air to flow through said at least one air outlet vent from the interior of said computer housing to the exterior of said computer housing and for preventing air from flowing through said at least one air outlet vent from the exterior of said computer housing to the interior of said computer housing.
Claim 8
Dependent Claim
45 words
The cooling system of claim 1 further comprising a switch means for simultaneously supplying electrical power to said personal computer and said at least once air blower means, such that said at least one air blower means will always operate whenever said personal computer operates.
