Abstract

A computer housing which includes a chassis that has a first compartment and a second compartment. The first compartment includes a first electronic assembly and a first fan that creates a flow of air through the compartment to create a compartment pressure that is less than an ambient pressure. The second compartment contains a second electronic assembly and a second fan which produces a flow of air that creates pressure within the compartment that is greater than the ambient pressure. The housing also contains an inner wall which separates the first compartment from the second compartment to inhibit air flow between the compartments.

Claims

1. A computer housing, comprising:

a chassis which has an outer wall and a first inner wall which define a first compartment and a second compartment, said chassis further having a second inner wall that is separated from said first inner wall by a third compartment;

a first electronic assembly within said first compartment;

a second electronic assembly within said second compartment;

a third electronic assembly within said third compartment;

a power supply located within said first compartment and is electrically coupled to said first, second and third assemblies;

a pair of first fans that are within said first compartment and induce a first flow of air through said first compartment;

a second fan that is attached to said chassis and induces a second flow of air through said second compartment; and

,

a third fan that is attached to said chassis and induces a third flow of air through said third compartment.

2. The housing as recited in claim 1, wherein said first fan creates a pressure within said first compartment that is less than an ambient pressure.

3. The housing as recited in claim 2, wherein said second fan creates a pressure within said second compartment that is greater than an ambient pressure.

4. The housing as recited in claim 3, wherein said third fan creates a pressure within said third compartment that is greater than an ambient pressure.

5. The housing as recited in claim 1, further comprising an ambient temperature sensor that senses an ambient temperature and is coupled to a controller of said first fan, said controller varies a speed of said first fan in response to a change of the ambient temperature.

6. The housing as recited in claim 1, further comprising a temperature sensor that senses a temperature of said third electronic assembly and is coupled to a controller of said third fan, said controller varies a speed of said third fan in response to a change of the temperature.

7. The housing as recited in claim 1, wherein said second electronic assembly includes an electronic card, and said chassis includes a cover that encloses said second compartment and which has an outwardly tapered wall that extends toward said second electronic assembly so that the second air flow flows directly across said electronic card.

8. The housing as recited in claim 7, wherein said third electronic assembly includes a shroud that is attached to an electronic card, said shroud has an opening which directs the third air flow across said electronic card.

9. A computer housing, comprising:

a chassis which has an outer wall and a first inner wall which define a first compartment and a second compartment, said chassis further having a second inner wall that is separated from said first inner wall by a third compartment;

a first electronic assembly within the first compartment;

a second electronic assembly within the second compartment;

a third electronic assembly within the third compartment;

wherein said third electronic assembly includes a shroud that is attached to an electronic card;

a pair of first fans that are within said first compartment and induce a first flow of air through said first compartment;

a second fan that is attached to said chassis and induces a second flow of air through said second compartment; and

,

a third fan that is attached to said chassis and induces a third flow of air through said third compartment.
