Abstract
A well tool can include a well tool housing and a cooling section positioned within the well tool housing, the cooling section including a helical cooling fluid flow path, and the flow path having a reversal of direction proximate an end of the cooling section. Another well tool can include a cooling fluid which flows through the helical flow path toward the end of the cooling section in one direction, and which flows through the helical flow path away from the end of the cooling section in an opposite direction. Another well tool can include the cooling fluid which flows through the helical flow path, and which makes multiple passes longitudinally through the cooling section proximate a heat-sensitive device.
