Patent ID: 7483471

Claim:
A cooling device for use in a high temperature environment comprising: a first cooling cavity having a first cross sectional area, a first end, a second end, and a central axis between the first end and the second end of the first cooling cavity; a first cooling tube having a second cross sectional area, a first end, a second end, and a central axis between the first and second end of the first cooling tube, the first cooling tube being inserted through the first end of the first cooling cavity; the first cooling tube being adapted to eject a cooling fluid through the second end of the first cooling tube; the first cooling cavity and the first cooling tube aligned substantially coaxially; a second cooling cavity having a third cross sectional area substantially equal to the first cross sectional area, a first end, a second end, and a central axis between the first end and the second end of the second cooling cavity; a second cooling tube having a fourth cross sectional area, a first end, a second end, and a central axis between the first and second end of the second cooling tube, the second cooling tube being inserted through the open end of the second cooling cavity; the second cooling cavity and the second cooling tube aligned substantially coaxially; the second cooling tube being adapted to eject a cooling fluid through the second end; and a cooling fluid distribution section adapted to distribute cooling fluid to the first cooling tube and the second cooling tube.
