Cooled electric assembly
View Patent ↗A cooled electric assembly includes a box that defines an interior space. An electrical conductor is located within the interior space. A cooling tube is attached to the box. A thermal conductor is located at least partially within the interior space and is in thermal contact with the electrical conductor and in thermal contact with the cooling tube.
1. A cooled electric assembly comprising:
a box that defines an interior space;
an electrical conductor located within the interior space of the box;
a cooling tube having at least a portion that is located within the interior space of the box; and
a thermal conductor in thermal contact with both the electrical conductor and the cooling tube;
characterized in that a resistor included in an electric circuit is disposed within the interior space of the box and is attached to the portion of the cooling tube that is located within the interior space of the box, and wherein
the cooling tube extends between a pipe inlet that is located outside the interior space of the box and a pipe outlet that is located outside the interior space of the box.
2. The cooled electric assembly of claim 1 , wherein the thermal conductor is in thermal contact with limited, discrete positions of the cooling tube.
3. The cooled electric assembly of claim 1 , further comprising a second electrical conductor located within the interior space of the box; and a second thermal conductor in thermal contact with both the second electrical conductor and the cooling tube.
4. The cooled electric assembly of claim 1 , wherein the box is connected to a portion of the cooling tube.
5. The cooled electric assembly of claim 1 , wherein the cooling tube is adapted to pass a liquid coolant therethrough.
6. The cooled electric assembly of claim 1 , wherein the cooling tube is a seamless tube between the pipe inlet and the pipe outlet.
7. The cooled electric assembly of claim 6 , wherein the cooling tube has a relatively constant-cross-section between the pipe inlet and the pipe outlet.
8. The cooled electric assembly of claim 6 , wherein the box is connected to portions of the cooling tube.
9. The cooled electric assembly of claim 6 , wherein the thermal conductor is in thermal contact with the cooling tube at limited, discrete positions thereof.
10. A cooled electric assembly comprising:
a box that defines an interior space;
an electrical conductor located within the interior space of the box;
a seamless cooling tube located within the interior space of the box and extending between a pipe inlet that is located outside the interior space of the box and a pipe outlet that is located outside the interior space of the box, wherein at least a portion of the cooling tube is located within the interior space of the box;
a thermal conductor in thermal contact with both electrical conductor and the cooling tube; and
a resistor within the interior space of the box and attached to the cooling tube, the resistor included in an electric circuit.
