Cooling computer components

1. In a computer system in which a central processing unit generates heat while in operation, said processing unit is mounted on a motherboard and said processing unit communicates with a storage device, an apparatus for cooling said motherboard, comprising:

a substantially airtight container comprising a lid, the container being configured to enclose said motherboard, the motherboard being suspended from the lid so as to avoid contact with the sides of the container;

a liquid contained within said container and surrounding said motherboard such that said motherboard is immersed in said liquid so as to remove heat from said processing unit;

a cooling system configured to cool the interior of the container; and

a serial data connection extending from said container to provide serial communication between said processing unit and said storage device.

2. The apparatus according to claim 1 , wherein said substantially airtight container has an opening that is closed by the application of the lid, each provided with a lip such that a seal is formed when said lips are brought into contact.

3. The apparatus according to claim 1 , wherein said liquid is oil.

4. The apparatus according to claim 1 , wherein said cooling system comprises an evaporator coil within the liquid, a pump connected to said coil by pipes and a condenser connected to the pump and the coil by pipes, wherein said cooling system includes a coolant to provide a working fluid.

5. The apparatus according to claim 1 , including a peltier element in thermal contact with the processing unit.

6. The apparatus according to claim 5 , wherein a heatsink is in thermal contact with the peltier element.

7. The apparatus according to claim 1 , including an agitator arranged to agitate the liquid contained within the container.

8. The apparatus according to claim 1 , wherein a desiccant material is contained within the container.

9. A computer system, comprising:

a motherboard having at least one processing unit mounted thereon that generates heat while in operation;

at least one storage device separate from said motherboard;

a substantially airtight container, comprising a lid, the container containing a liquid into which said motherboard is immersed so as to remove heat from said motherboard, and the motherboard being suspended from the lid so as to avoid contact with the sides of the container;

a serial communication cable extending through an airtight hole in said container to provide serial communication between said processing unit and said storage device; and

a cooling system configured to cool the interior of the container; and

a serial data connection extending from said container to provide serial communication between said processing unit and said storage device.

10. The computer system according to claim 9 , wherein the container is surrounded by insulating material to prevent heat taken outside the container from re-entering the container.

11. The computer system according to claim 10 , in which the insulated container and the data storage device are housed in a case and a second cooling unit is provided for removing heat from said container.

12. A method of cooling heat generating electrical components arranged on a board, comprising the steps of:

forming a substantially airtight container with a lid, said lid being removed;

connecting said board via a serial cable to an external storage device via a substantially airtight hole in said container;

pouring a liquid into the container such that the board is immersed in said liquid when the board is inserted into the container;

placing a cooling system inside said container so as to remove heat from the inside of said container;

suspending the board from the lid such that when the lid is applied, the board will avoid contact with the sides of the container;

applying said substantially airtight lid, such that the board is inserted into the container; and

activating said cooling system.

13. The method according to claim 12 wherein a substantial proportion of said heat is generated by one or more integrated processing units.

14. The method according to claim 13 , wherein said processing units have a recommended clock speed for operation in ambient conditions, wherein said processing units are arranged to operate at a faster clock speed than the recommended clock speed.

15. The method according to claim 13 , wherein additional cooling devices are applied directly to said processing units in the container.

16. The method according to claim 12 , wherein the liquid in the container is agitated.

17. The method according to claim 12 , wherein insulation is applied to the outside of said container.

18. The method according to claim 17 , wherein the insulated container and the storage device are placed in a case and an additional cooling system is arranged to remove heat from said case.
