Abstract
A steam generator is located downhole in a well for generating steam to cause viscous crudes to flow out adjacent walls. A packer is mounted above the steam generator. A connector box is located between the packer and the steam generator. An electrical cable extends alongside tubing into the well and into a window in the tubing located just above the packer. The cable extends through a passage in the packer and into the connector box. Feedthrough connectors in the connector box connect the power cable with lead wires extending upward from the steam generator. Heat pipes extend from the connector box upward through the packer. The heat pipes contain gas which circulates to aid in dissipating heat from the connector box.
