Abstract

A computer apparatus comprising a computer chassis, a baseboard component disposed within the computer chassis and a computer module electronically coupled to the baseboard component is disclosed. A heat sink assembly is attached to the computer module to form a computer module heat sink assembly, wherein the heat sink assembly forms part of an integral exterior structure of the computer chassis. The chassis may comprise a compartment disposed through an exterior surface of the chassis for receiving the computer module heat sink assembly in mated fashion. The computer module heat sink assembly forms a water and air tight seal with the internal compartment of the chassis in mated fashion.

Claims

1. A computer apparatus comprising:

a computer chassis;

a computer module, said computer module supporting a computer-on-module (COM) format and including a plurality of electrical components, a bus for input/output peripherals, and computer module connectors;

a baseboard disposed in said computer chassis, said baseboard including baseboard connectors that are coupled to the computer module connectors, said baseboard breaking out said bus of said computer module to peripheral connectors for said input/output peripherals;

a heat sink assembly attached to said computer module to form a computer module-heat sink assembly, said heat sink assembly being disposed on a first side of said computer module-heat sink assembly and said computer module being disposed on a second side of said computer module-heat sink assembly, said second side being opposite said first side, said electrical components and said computer module connectors of said computer module facing outwardly from said second side, each of said electrical components being removable from said computer module without detaching said computer module from said heat sink assembly, and said computer module connectors extending from said second side into the coupling with the baseboard connectors,

wherein said computer module-heat sink assembly is configured to be alternately removed or attached to said computer chassis, and when said computer module-heat sink assembly is attached to said computer chassis, said heat sink assembly forms part of an integral exterior structure of said computer chassis.

2. The apparatus of claim 1, wherein the heat sink assembly is attached to said computer chassis via one or more fasteners.

3. The apparatus of claim 1, wherein the computer module supports COMExpress format.

4. The apparatus of claim 1, further comprising a computer bus interface for connecting host bus adapters to mass storage devices.

5. The apparatus of claim 4, wherein the computer bus interface includes Serial Advanced Technology Attachment (SATA) technology.

6. The apparatus of claim 1, wherein the heat sink assembly is directly attached to the computer module.

7. The apparatus of claim 1, wherein the apparatus is configured to dissipate heat through the computer module heat sink assembly and exterior to the apparatus.

8. The apparatus of claim 1, wherein the apparatus is configured to dissipate heat through the computer module into the heat sink assembly and exterior to the apparatus.

9. The apparatus of claim 1, wherein said computer module includes a circuit board, and said plurality of electronic components are coupled to said circuit board.

10. The apparatus of claim 1, further comprising an internal compartment extending inwardly from said an exterior surface of said chassis for receiving said computer module heat sink assembly in mated fashion, said baseboard connectors being disposed in said internal compartment.

12. The apparatus of claim 10, wherein the computer module heat sink assembly comprises a plurality of fins integrated on a surface thereon, and the exterior of the chassis comprises a plurality of integrated fins, wherein the fins of the computer module heat sink assembly and the fins of the chassis form an integrated fin structure when the computer module heat sink assembly is mated with the compartment of the chassis.

11. The apparatus of clam 10, wherein the computer module heat sink assembly forms a water and air tight seal with the internal compartment of the chassis in mated fashion.

13. A method of manufacturing an electronic device, comprising:

providing a computer chassis, a computer module, a baseboard, and a heat sink assembly, said computer module supporting a computer-on-module (COM) format and including a plurality of electrical components, a bus for input/output peripherals, and computer module connectors, said baseboard disposed in said computer chassis and including baseboard connectors;

attaching said heat sink assembly to said computer module to form a computer module-heat sink assembly, said heat sink assembly being disposed on a first side of said computer module-heat sink assembly and said computer module being disposed on a second side of said computer module-heat sink assembly, said second side being opposite said first side, said electrical components and said computer module connectors of said computer module facing outwardly from said second side, each of said electrical components being removable from said computer module without detaching said computer module from said heat sink assembly, and said computer module connectors extending from said second side; and

removably attaching said computer module-heat sink assembly to said computer chassis so that said heat sink assembly forms part of an integral exterior structure of said computer chassis and so that said computer module connectors are coupled with said baseboard connectors, said baseboard being coupled to said computer module to break out said bus of said computer module to peripheral connectors for said input/output peripherals.

14. The method of claim 13, wherein said computer module includes a circuit board, and said plurality of electronic components are coupled to said circuit board.

15. The method of claim 13, further comprising:

positioning, in mated fashion, said computer module-heat sink assembly in an internal compartment extending inwardly from an exterior surface of said chassis, said baseboard connectors being disposed in said internal compartment.

17. The method of claim 15, further comprising:

forming a plurality of fins integrated on a surface of the computer module-heat sink assembly;

forming a plurality of fins integrated on the exterior of the chassis; and

forming an integrated exterior fin structure formed by the fins of the computer module-heat sink assembly and the fins of the chassis when the computer module-heat sink assembly is mated with the compartment of the chassis.

16. The method of clam 15, further comprising:

forming a water and air tight seal with the internal compartment of the chassis via the computer module heat sink assembly.
